Apparatus for Improving the Noticeability of a Hat
An apparatus is presented for improving the noticeability of a hat. The apparatus includes a light source configured to produce light upon receiving electrical energy. The apparatus also includes a mount coupled to the light source and configured to selectively attach to and detach from the hat. The mount, when attached to the hat, orients the light source to project light onto an exterior surface of the hat. The apparatus additionally includes a battery receptacle electrically-coupled to the light source and having electrical contacts for coupling to one or more batteries. Hats having improved noticeability and methods for improving the noticeability of a hat are also presented.
The present disclosure relates generally to hats, and more particularly, to apparatus that improve the noticeability of a hat.
2. BACKGROUNDHats are commonly used to cover a portion of a head, which typically includes a crown of the head. Hats may provide protective functionality, and due to their prominent position, may also serve as aesthetic attire that complements an overall appearance of a wearer. Moreover, hats may serve to communicate information, such as status (e.g., social, military, professional, etc.) or affiliation (e.g., religious, political, corporate, sports, etc.). As such, the usefulness of a hat may be influenced by its ability to be seen.
The noticeability of a hat typically depends on lighting conditions within its ambient environment, which affects the hat's visibility to an observer. Such dependency requires that light directly illuminate one or more surfaces of the hat. A hat entering an ambient environment of little or no illumination may thus be unnoticed by an observer, resulting in a loss of usefulness to the wearer. Such loss may include an inability of the observer to discern decorative patterns, ornamental features, textures, text, logos, and so forth, of the hat. Such loss may also involve an inability of the observer to locate the wearer, which may be relevant in situations where safety is of concern. Hats having improved noticeability are therefore desirable, especially in dim or dark environments.
BRIEF SUMMARYIn one aspect, the disclosure is directed to an apparatus for improving the noticeability of a hat. The apparatus includes a light source configured to produce light upon receiving electrical energy. The light source may include at least one of a refractive element, a reflective element, a diffractive element, and an optically-transmissive element. The apparatus also includes a mount coupled to the light source and configured to selectively attach to and detach from the hat. The mount, when attached to the hat, orients the light source to project light onto an exterior surface of the hat. The mount may include a clip configured to insert into an orifice of the hat. The apparatus additionally includes a battery receptacle electrically coupled to the light source and having electrical contacts for coupling to one or more batteries. In some embodiments, the apparatus includes a switch configured to regulate a flow of electrical energy from the battery receptacle to the light source. In some embodiments, a charging circuit is electrically-coupled to the battery receptacle and configured to regulate at least one of a charging voltage and a charging current supplied thereto.
In another aspect, the disclosure is directed to a hat having improved noticeability. The hat includes an exterior surface that is visible when the hat is worn. The hat also includes a light source coupled to the hat and configured to illuminate the exterior surface upon receiving electrical energy. The hat additionally includes a battery receptacle having electrical contacts for coupling to one or more batteries. The battery receptacle is electrically-coupled to the light source, and in some embodiments, is configured to selectively attach to and detach from the hat. In some embodiments, the hat includes a mount coupling the light source to the hat and configured to selectively attach to and detach from the hat. The mount, when attached to the hat, orients the light source to project light onto the exterior surface of the hat. The hat may include an orifice for receiving a clip of the mount. In some embodiments, a charging circuit is electrically-coupled to the battery receptacle and configured to regulate at least one of a charging voltage and a charging current supplied thereto.
In yet another aspect, the disclosure is directed to a method for improving the noticeability of a hat. The method includes producing light from a light source coupled to the hat. The light source is configured to produce light upon receiving electrical energy. The method also includes orienting the light source such that light therefrom illuminates an exterior surface of the hat. While orienting the light source, the method may optionally involve distributing light across the exterior surface using at least one of a refractive element, a reflective element, a diffractive element, and an optically-transmissive element. In some embodiments, the method includes altering an amount of electrical energy received by the light source to alter an intensity of light produced therefrom. In further embodiments, altering the amount of electrical energy includes altering the amount of electrical energy in response to an intensity of ambient light measured by a photosensor.
Illustrative embodiments of the present disclosure are described in detail below with reference to the attached drawing figures, which are incorporated by reference herein.
The figures described above are only exemplary and their illustration is not intended to assert or imply any limitation with regard to the environment, architecture, design, configuration, method, or process in which different embodiments may be implemented.
DETAILED DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTSIn the following detailed description of the illustrative embodiments, reference is made to the accompanying drawings that form a part hereof. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention, and it is understood that other embodiments may be utilized and that logical structural, mechanical, electrical, and chemical changes may be made without departing from the scope of the invention. To avoid detail not necessary to enable those skilled in the art to practice the embodiments described herein, the description may omit certain information known to those skilled in the art. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the illustrative embodiments is defined only by the appended claims.
In the drawings and description that follow, like parts are typically marked throughout the specification and drawings with the same reference numerals or coordinated numerals. The drawings (or figures) are not necessarily to scale. Certain features of the illustrative embodiments may be shown exaggerated in scale or in somewhat schematic form and some details of conventional elements may not be shown in the interest of clarity and conciseness.
Workers in many industries commonly wear impact-resistant hats or helmets adapted for tasks and environments within those specific industries. For example, and without limitation, workers in the construction industry may wear “hard” hats to protect against head injuries (e.g., from falling debris, loss of balance, etc.). In another example, workers in the firefighting industry may wear “hard” hats that, in addition to protecting against head injuries, are augmented with breathing systems to avoid inhalation of smoke and hazardous gases. In yet another example, workers in the steel industry may wear “hard” hats formed of heat-resistant materials (e.g., fiberglass) that both protect against heat injuries and shield against high temperatures associated with molten steels.
Current hats for industrial use, however, are poorly-suited to provide noticeability for a wearer in environments of little to no illumination, e.g., at night, during foggy or rainy weather, in unlit rooms, behind large equipment, underwater, and so forth. Such noticeability may involve visibility to an observer (e.g., other workers), visibility to an optical system (e.g., a camera), or both. To the extent that these hats even address noticeability, the hats may incorporate passive optical elements that require an external light source for illumination (e.g., reflective tape or paint). However, the use of such elements requires an unobscured line of sight between the hats and their corresponding external light sources. Smoke, airborne dust, fog, rain, and so forth may reduce a performance of the elements by attenuating an intensity of light along the line of sight. But even if the intensity of light is unattenuated, external light sources may be directed to illuminate objects and areas other than a hat. Thus, light reaching the hat may be indirect and reduced in intensity.
To illustrate a representative example of such a situation,
The embodiments described herein relate to apparatus for improving the noticeability of a hat by illuminating an exterior surface of the hat. In one aspect, an apparatus for improving the noticeability of a hat includes a light source configured to produce light upon receiving electrical energy. The apparatus also includes a mount coupled to the light source and configured to selectively attach to and detach from the hat. The mount, when attached to the hat, orients the light source to project light onto an exterior surface of the hat. The apparatus additionally includes a battery receptacle electrically-coupled to the light source that includes electrical contacts for coupling to one or more batteries.
The embodiments described herein also relate to hats having improved noticeability by including a light source to illuminate an exterior surface of the hats. In one aspect, a hat having improved noticeability includes an exterior surface that is visible when the hat is worn. The hat also includes a light source coupled to the hat and configured to illuminate the exterior surface upon receiving electrical energy. A battery receptacle is electrically-coupled to the light source and includes electrical contacts for coupling to one or more batteries. In some embodiments, the battery receptacle is configured to selectively attach to and detach from the hat.
The embodiments described herein additionally relate to methods for illuminating an exterior surface of a hat, thereby improving the noticeability of the hat. In one aspect, a method for improving the noticeability of a hat includes producing light from a light source coupled to the hat. The light source is configured to produce light upon receiving electrical energy. The method also includes orienting the light source such that light therefrom illuminates an exterior surface of the hat.
It will be understood that the apparatus, hats, and methods described herein may be applicable to any type of environment, including those associated with construction sites, refineries, oil and natural gas exploration, chemical processing plants, mining, fire prevention and rescue, manufacturing, metal foundries, ports and docks, and harbors. The apparatus, hats, and methods are also applicable in non-industrial settings such in casual and formal dress settings. As such, the apparatus, hats, and methods may be directed towards improving the noticeability of decorative patterns, ornamental features, textures, reflective elements, text, logos, and so forth present on an exterior surface of a hat.
As used herein, the term “hat” refers to any type of covering for a head that includes at least a crown of the head. Non-limiting examples of a “hat” include a beanie, a top hat, a beret, a sombrero, a hard hat, a helmet, a baseball cap, a boater, a knit cap, a fedora, a cowboy hat, a balaclava, a bowler, a garrison hat, a bucket hat, a fruit hat, a Fulani hat, a kepi, an umbrella hat, a flat cap, a fez, a deerstalker, a conical hat, an eight-point cap, and an aviator hat. Other types of “hats” are possible. As used herein, the terms “front”, “left”, “right”, and “rear”—when describing sides of the “hat” and surfaces thereof—refer to sides of the “hat” that align with respective sides of a wearer when the “hat” is worn.
The “hat” may formed of any type of material including biologically-derived materials, plastics, epoxies, metals, and ceramics. Such materials may be solid, woven into fabrics, or combined into composite structures (e.g., a plurality of layers, fibers in a matrix, etc.). Non-limiting examples of biologically-derived materials include leather, silk, wool, jute, cotton, linen, hemp, fleece, rayon, and cashmere. Non-limiting examples of plastics include aramid, polyester, nylon, polypropylene, polyethylene, polycarbonate, acrylonitrile butadiene styrene, phenol formaldehydes, and poly(methyl methacrylate). Non-limiting examples of epoxies include cured resins based on bisphenol A resin, bisphenol F resin, glycidylamine resin, aliphatic resin, and novolac resin. Non-limiting examples of metals include aluminum and aluminum alloys, steel, titanium and titanium alloys, and magnesium and magnesium alloys. Non-limiting examples of ceramics include graphite, silicon oxide, aluminum oxide, zirconium oxide, silicon carbide, silicon nitride, SiAlON, A-glass, C-glass, D-glass, E-glass, E-CR-glass, R-glass, and S-glass. The “hat” may also be formed of natural materials, including blends of natural materials with synthetic materials.
Unless otherwise specified, any use of any form of the terms “connect,” “engage,” “couple,” “attach,” or any other term describing an interaction between elements is not meant to limit the interaction to direct interaction between the elements and may also include indirect interaction between the elements described. In the following discussion and in the claims, the terms “including” and “comprising” are used in an open-ended fashion, and thus should be interpreted to mean “including, but not limited to”. Unless otherwise indicated, as used throughout this document, “or” does not require mutual exclusivity.
The various characteristics mentioned above, as well as other features and characteristics described in more detail below, will be readily apparent to those skilled in the art with the aid of this disclosure upon reading the following detailed description of the embodiments, and by referring to the accompanying drawings. Other means may be used as well.
Now referring to
The one or more light-emitting elements 204 may include individual elements having an emission of light narrowly distributed around a central wavelength, i.e., a narrow-band emission of light. The narrow-band emission of light may have a full-width half maximum (FWHM) of up to 50 nm. In many embodiments, the FWHM is at least 20 nm but no greater than 30 nm. Non-limiting examples of the narrow-band emission of light include a red emission (i.e., 620 nm≤λcentral≤750 nm), a green emission (i.e., 495 nm≤λcentral≤570 nm), and a blue emission (i.e., 450 nm≤λcentral≤495 nm). Other types of emissions are also possible (e.g., an orange emission, a yellow emission, a violet emission, etc.). For example, and without limitation, the one or more light-emitting elements 204 may include a light-emitting diode having a narrow-band emission of green light centered at 555 nm with a FWHM of about 25 nm.
The one or more light-emitting elements 204 may also include individual elements having an emission of light broadly distributed across a spectrum, i.e., a broad-band emission of light. Non-limiting examples of the broad-band emission of light include a “soft” white light (i.e., 2500 K≤Tcolor≤3000 K), a “warm” white light (i.e., 3500 K≤Tcolor≤4100 K), and a “daylight” white light (i.e., 5000 K≤Tcolor≤6500 K). Other types of broad-band emissions are possible. For example, and without limitation, the one or more light-emitting elements 204 may include an incandescent lamp having a broad-band emission of “warm” white light corresponding to a color temperature of 2700K.
In some embodiments, the one or more light-emitting elements 204 include groups of light-emitting elements 204, each configured to produce a specific narrow-band or broad-band emission. In these embodiments, the groups of light-emitting elements 204 may be selectively energized to allow the light source 202 to produce a specific emission (or emissions) of light. For example, and without limitation, the one or more light-emitting elements 204 may include a first group of light-emitting elements 204 configured to emit a red light and a second group of light-emitting elements 204 configured to emit a “soft” white light of 3000K color temperature. The first and second groups may be energized separately such that the light source 202 produces, respectively, the red light or the “soft” white light. The first and second groups may also be energized together to produce a “soft” white light having a strong red component.
In some embodiments, the light source 202 includes at least one of a refractive element (e.g., a lens), a reflective element (e.g., a mirrored surface, a light-scattering surface, etc.), a diffractive element (e.g., a Fresnel lens, a diffractive optic, etc.), and an optically-transmissive element (e.g., a transparent plate, a light pipe, etc.). In
Optical elements, such as those disclosed above, may allow the light source 202 define a distribution of light projected from the one of more light-emitting elements 204. The distribution of light may be any spatial distribution of light and may involve intensity distributions within the spatial distributions of light. Non-limiting examples of the distribution of light include a uniform distribution, a gradient distribution, and a patterned distribution. For the patterned distribution, the optical elements may include a stencil with apertures corresponding to a pattern (e.g., text). In defining the distribution of light, the optical elements may correct for a curvature of one or more surfaces of the hat. This correction may reduce deviations from a desired illumination of the hat, such as a uniform illumination.
The apparatus 200 also includes a mount 210 coupled to the light source 202 and configured to selectively attach to and detach from the hat. The mount 210 may be formed of any type of structural material including metals, plastics, ceramics, and composites. The mount 210 is operable to secure the light source 202, and in many embodiments, also serves as a housing for components of the apparatus 200. Non-limiting examples of such components include the light-emitting elements and optical elements; batteries and compartments therefor; electrical circuitry, printed circuit boards, and wiring; and electrical-power connectors, indicator lights, informational displays, and user-operated switches. The mount 210 may be matched to a curvature of the hat to keep a distance between the light source 202 and surfaces of the hat constant (or approximately constant). Such matching may also reduce a protrusion of the mount 210 from the hat.
To selectively attach to and detach from the hat, the mount 210 may employ any type of reversible coupling. Non-limiting examples of such reversible couplings include those based on chemical adhesives, magnetic attraction, and mechanical fasteners. For example, and without limitation, the mechanical fasteners can include straps, ties, belts, clips, clasps, buckles, snaps, press studs, screws, draw latches, tension latches, toggle latches, hook and loop fasteners (e.g., Velcro®), brads, pins, and so forth. The mechanical fasteners can also involve elastic elements, such as straps, bands, or cords, capable of wrapping around or conforming to a shape of the hat. In some embodiments, such as shown
It will be appreciated that the mount 210, when attached to the hat 218, orients the light source 202 to project light onto an exterior surface of the hat 218. In
The mount 210 controls a direction of illumination from the light source 202, which involves controlling a position and orientation of individual light-emitting elements 204 (and respective optical elements if present). For example, and without limitation, the mount 210 shown in
The apparatus 200 additionally includes a battery receptacle 222 electrically coupled to the light source 202 and having electrical contacts for coupling to one or more batteries. The battery receptacle 222 may be disposed within the mount 210, such as depicted in
The battery receptacle 222 may be configured for any size battery, including custom-sized batteries and standard-sized batteries (e.g., AA, AAA, AAAA, C, D, A23, 9 Volt, CR2032, LR44, etc.). Custom-sized batteries may reduce a bulk of the battery receptacle 222, which in turn, may reduce a volume occupied by the apparatus 200. The battery receptacle 222 may be configured for any type of battery, including primary (or non-rechargeable) and secondary (or rechargeable) batteries. Non-limiting examples of primary batteries include alkaline batteries and zinc-carbon batteries. Non-limiting examples of secondary batteries include silver-zinc batteries, nickel-cadmium batteries, and lithium-ion batteries. In some embodiments, the battery receptacle 222 includes the one or more batteries.
In some embodiments, the battery receptacle 222 allows the one or more batteries to be selectively inserted into and removed from the apparatus 200. For example, and without limitation, the battery receptacle 222 may include a detachable wall 224 covering an opening of a cavity (e.g., a slideable door). The detachable wall 224 facilitates removal of the one or more batteries from the apparatus 200 (e.g., for replacement or recharging). In other embodiments, the battery receptacle 222 is sealed such that the one or more batteries are non-removable. In these embodiments, the one or more batteries may have a limited number of charge-discharge cycles before the apparatus 200 becomes inoperable. For example, and without limitation, the one or more batteries may include secondary batteries that degrade rapidly after 100 charge-discharge cycles. This degradation may prevent the secondary batteries from supplying sufficient electrical energy to the apparatus 200 after 100 charge-discharge cycles. In another non-limiting example, the one or more batteries may correspond to primary batteries that irreversibly deplete after one charge-discharge cycle. It will be appreciated that, in embodiments where the battery receptacle 222 cannot be replaced and includes batteries limited to less than 20 charge-discharge cycles, the apparatus 200 may correspond to a “disposable” apparatus.
Electrical coupling of the battery receptacle 222 to the light source 202 may occur through an electrical circuit, which includes the electrical contacts of the battery receptacle 222. The electrical circuit is configured for voltages and currents of the one or more batteries. Moreover, the electrical circuit may electrically arrange the one or more batteries in a series configuration, a parallel configuration, or some combination thereof. In certain embodiments, the electrical circuit is configured such that the battery receptacle 222 can accept both primary and secondary batteries, but not in intermixed groups.
In many embodiments, the apparatus 200 includes a switch 226 configured to regulate a flow of electrical energy from the battery receptacle 222 to the light source 202. The switch 226 serves as part of the electrical circuit and regulates a voltage, a current, or both, received by the light source 202. The switch 226 may be a binary-type switch capable of transitioning between an “on” state, where electrical energy flows to the light source 202, and an “off” state, where no electrical energy flows to the light source 202. Non-limiting examples of the binary-type switch include toggle switches, push-button switches, and knife switches. Alternatively, the switch 226 may be a dimmer-type switch that, upon transitioning from an “on” state and an “off” state, progressively decreases (or increases) a magnitude of electrical energy flowing to the light source 202. Non-limiting examples of the dimmer-type switch include rotary switches and sliding switches. In some embodiments, the switch 226—whether a binary-type switch or a dimmer-type switch—is configured to selectively activate groups of light-emitting elements 204. Such groups may be associated with a characteristic, such as a location on the mount 218, an orientation on the mount 218, an emission type, a color of emission, and so forth. Groups of light-emitting elements 204 based on other characteristics are possible.
In embodiments where the battery receptacle 222 is capable of accepting secondary batteries, the apparatus 200 may optionally include a charging circuit electrically-coupled to the battery receptacle 222 and configured to regulate at least one of a charging voltage and a charging current supplied thereto. The charging circuit may reside within the mount 210, the battery receptacle 222, or some combination thereof. The charging circuit may also have a portion external to the apparatus 200 (e.g., an external AC-to-DC power converter). In some embodiments, the charging circuit is entirely external to the apparatus 200. The charging circuit is operable to recharge secondary batteries disposed within the battery receptacle 222, and may be capable of determining a state-of-charge of the secondary batteries, i.e., a percentage of full charge. Such determination may allow the charging circuit to cease supplying electrical energy to the secondary batteries when the state-of-charge reaches about 100%. In some embodiments, the charging circuit includes an indicator (e.g., a series of light-emitting diodes) or informational display (e.g., a liquid crystal display) to indicate the state-of-charge of the secondary batteries.
The charging circuit may include a connector 228 for coupling to an external power source. The connector 228 may correspond to an outer (or “female”) connector. Non-limiting examples of the connector 228 include a USB port (e.g., Micro, Mini, Type-C, etc.), a two-pin connector, and a barrel connector. The connector 228 may be protected via a cover 230 from dust, dirt, and contact with exterior objects. In
The charging circuit may be configured to electrically-couple the apparatus 200 to an AC power source, a DC power source, or both. Such coupling may occur through a physical connection (e.g., mating connectors) or wirelessly (e.g., magnetic coupling, capacitive coupling, etc.). Non-limiting examples of the AC power source include wall outlets associated with 120 VAC and 240 VAC “mains” power lines. Non-limiting examples of the DC power source include USB ports (e.g., in cars, computers, etc.), receptacles for lighting cigarettes, and portable solar panels. In some embodiments, the charging circuit is configured to be a DC circuit. In further embodiments, the connector 228 allows the charging circuit to selectively couple to and de-couple from an external AC-to-DC power converter, such as a switching-mode power supply. The external AC-to-DC power converter may be portable so that a user can easily transport and store the external AC-to-DC power converter. It will be appreciated that, by keeping circuitry associated with the external AC-to-DC power converter separate from the apparatus 200, the charging circuit may occupy less volume in the apparatus 200. The charging circuit may also add less weight to the apparatus 200.
In some embodiments, the apparatus 200 includes a photovoltaic device coupled to the mount 210. The photovoltaic device may be any type of electric device configured to receive light and convert such light into electrical energy. In many embodiments, the photovoltaic device includes one or more photovoltaic elements electrically-coupled in series, in parallel, or some combination thereof. Non-limiting examples of such photovoltaic elements include amorphous silicon photodiodes, polycrystalline silicon photodiodes, monocrystalline silicon photodiodes, cadmium telluride photodiodes, and copper indium gallium arsenide (CIGS) photodiodes. The photovoltaic device may be electrically-coupled to the light source 202, the battery receptacle 222, or both. In some embodiments, the photovoltaic device is electrically-coupled to the battery receptacle 222 through the charging circuit (i.e., electrically-coupled to the charging circuit). In some embodiments, the photovoltaic device includes a control switch to selectively activate and deactivate the photovoltaic device.
During deployment, a user of the apparatus 200 attaches the mount 210 to the hat 218, which may involve inserting the clip 212 into the orifice 216 of the hat 218. The clip 212 may lock to the hat 218 via the flexible detents 214. If the hat 218 has multiple orifices, the user may attach one instance of the apparatus 200 per orifice in any combination as desired. For example, and without limitation, one instance of the apparatus 200 may be attached to each of a left side and a right side of the hat 218. After attachment, the user of the apparatus 200 may don the hat 218, becoming a wearer of the hat 218 with the apparatus 200 coupled thereto.
Upon entering an area of little to no illumination, the user (or wearer) may choose to energize the light source 202. To energize the light source 202, the user actuates the switch 226 to the “on” state, which allows electrical energy to flow from the battery receptacle 222 to the light source 202. In response, the light source 202 produces light. If the switch 226 is a dimmer-type switch, the user may adjust an intensity of light produced by the light source 202. The mount 210 orients the light source 202 such that light therefrom projects onto the exterior surface of the hat 218. Projection of light onto the exterior surface of the hat 218 illuminates the hat 218, thereby improving its noticeability and that of the wearer.
When illumination of the hat 218 no longer desired, the user may de-energize the light source 202 by actuating the switch 226 to the “off” state. In this state, the user may choose to leave the apparatus 200 attached to the hat 218. However, in certain situations, such as those associated with battery replacement or recharging, the user may desire to detach the apparatus 200 from the hat 218. In these situations, the flexible detents 214 of the clip 212 may be displaced inward to unlock the mount 210 from the orifice 216 of the hat 218. The apparatus 200 may then be detached from the hat 218 by lifting the clip 212 out of the orifice 216.
During use of the apparatus 200, the light source 202 may deplete the one or more batteries such that insufficient electrical energy is stored therein (e.g., insufficient to energize the light source 202). Replacement of the one or more batteries is facilitated by removing the detachable wall 224 from the mount 210, which provides access to the battery receptacle 222 and the one or more batteries therein. However, if the one or more batteries correspond to secondary batteries, the user may choose instead to recharge the one or more batteries by energizing the charging circuit. Energizing the charging circuit may involve opening the cover 230 to expose the connector 228. The connector 228 is then coupled to a source of electrical energy. For example, and without limitation, the connector 228 may be coupled to an AC-to-DC power converter, which in turn, is plugged into a wall outlet supplying 120 VAC electrical power. In another non-limiting example, the connector 228 may be coupled to a DC-to-DC power converter, which in turn, is plugged into a cigarette-lighting receptacle of a vehicle. Once the one or more batteries are recharged to a level desired by the user, the charging circuit is de-energized by de-coupling the source of electrical energy from the connector 228 and closing the cover 230.
If the photovoltaic device 232 is present, the photovoltaic device 232 may be used to convert light from an ambient environment of the apparatus 200 into electrical energy. The ambient environment may correspond to that when the apparatus 200 is attached to the hat 218, or alternatively, to that when the apparatus 200 is detached from the hat 218. It will be appreciated that the photovoltaic device 232 may be used to recharge the one or more batteries when such batteries are secondary batteries. This recharging may postpone or eliminate a need to receive electrical energy from a direct source (e.g., a wall outlet, a portable solar panel, a cigarette-lighting receptacle, etc.). The photovoltaic device 232 may operate collectively with the charging circuit to recharge the one of more batteries. For example, and without limitation, the user may walk around in sunlight with the hat 218 donned and the apparatus 200 coupled thereto. Light received by the photovoltaic device 232 is converted into electrical energy, which in turn, is received by the charging circuit. The charging circuit manipulates the received electrical energy to produce an output voltage, an output current, or both, suitable for recharging the one or more batteries. Thus, during walking, the one or more batteries may charge sufficiently that use of the apparatus 200 can continue into nightfall without requiring recharging by a direct source of electrical energy.

Now turning back to
The mount 308, when attached to the hat 316, orients the plurality of light sources 302 to project light onto an exterior surface of the hat 316. Due to circumferential placement of the plurality of light sources 302, the exterior surface includes a band encircling the hat 316. The plurality of light sources 302, when energized, may illuminate the band continuously along its circumference. Such continuous illumination is aided by the curved, hemispherical lenses 306, which broaden a distribution of light produced by each strip light-emitting diode 304. It will be understood, however, that the plurality of light sources 302 is not restricted to continuous illumination of the band. The plurality of light sources 302 may be configured such that the band is illuminated discontinuously, i.e., illuminated portions separated by unilluminated or poorly-illuminated portions. For example, and without limitation, the plurality of light sources 302 could correspond to three light sources, one disposed adjacent each of a front-side exterior surface, a left-side exterior surface, and a right-side exterior surface. Portions of the band centered between the three light sources, especially at a rear-side exterior surface, would receive reduced (or no) illumination relative to portions immediate adjacent to the three light sources.
The apparatus 300 additionally includes a battery receptacle 320 electrically-coupled to the plurality of light sources 302 and having electrical contacts for coupling to one or more batteries. Electrical coupling of the battery receptacle 320 to the plurality of light sources 302 may occur through an electrical circuit, which includes the electrical contacts of the battery receptacle 320. In
Unlike battery receptacle 222 of
The apparatus 300 includes a switch 322 configured to regulate a flow of electrical energy from the battery receptacle 320 to the plurality of light sources 302. The apparatus 300 also includes a photosensor 324 configured to measure an intensity of light in an ambient environment of the apparatus 300 (or the hat 316). The photosensor 324 is operable to regulate the flow of electrical energy from the battery receptacle 320 to the plurality of light sources 302 in response to the measured intensity of light. The photosensor 324 may serve as part of the electrical circuit and may be disposed on any outward-facing surface of the apparatus 300. Non-limiting examples of the photosensor 324 include a photodiode, a photoresistor, and a phototransistor. Although
In embodiments where both the switch 322 and the photosensor 324 are present, the photosensor 324 may regulate the flow of electrical energy within bounds set by the switch 322. For example, and without limitation, the switch 322 may be a binary-type switch having an “on” state and an “off” state. In the “on” state, the switch 322 allows the battery receptacle 320 to produce a flow of electrical energy corresponding to a maximum possible flow given an instant state-of-charge in the one or more batteries. The photosensor 324 then regulates this flow of electrical energy in response to measuring the intensity of light. In the “off” state, the switch 322 blocks the flow of electrical energy to the plurality of light sources 302 and the photosensor 324 is disabled. In another non-limiting example, the switch 322 may be a dimmer-type switch that selectively sets a “cap” on the flow of electrical energy. The “cap” represents an upper limit that is equal to or less than the maximum possible flow given the instant state-of-charge in the one or more batteries. The photosensor 324 regulates the flow of electrical energy, but within a bound from zero up to and including the “cap” set by the switch 322. In the “off” state, the switch 322 blocks the flow of electrical energy to the plurality of light sources 302 and the photosensor 324 is disabled.
In some embodiments, the photosensor 324 includes a sensitivity selector 326 to alter a sensitivity of the photosensor 324 to light. Non-limiting examples of the sensitivity selector 326 include a rotary dial, a multi-position toggle, and a slide. The sensitivity selector 326 may set a lower limit, an upper limit, or both, of light intensity that the photosensor 324 responds to. In some embodiments, the photosensor 324 includes a control switch 328 to activate or deactivate the photosensor 324. In these embodiments, the control switch 328 may be operable to bypass the photosensor 324 on the electrical circuit.
During operation, the photosensor 324 may dynamically alter an illumination of the exterior surface (e.g., the band) in response to measurements of ambient light. Such alteration can occur without intervention of the wearer and may ensure that the plurality of light sources 302 illuminates the exterior surface with an intensity of light commensurate to the ambient light. For example, and without limitation, if the apparatus 300 leaves a brighter environment and enters a darker environment, the photosensor 324 may increase the flow of electrical energy to the plurality of light sources 302, thereby increasing an intensity of light produced therefrom. Conversely, if the apparatus 300 leaves a darker environment and enters a brighter environment, the photosensor 324 may decrease the flow of electrical energy to the plurality of light sources 302, thereby decreasing an intensity of light produced therefrom. Such dynamic alteration may reduce an unnecessary consumption of electrical energy by the plurality of light sources 302, especially if ambient lighting conditions change frequently.
In
As used herein, the term “indirect”, when describing illumination, refers to illumination by a light source whose position, orientation, or both, precludes a direct line-of-sight to a desired exterior surface of a hat. Optical elements may be used to guide light from the light source to the exterior surface, which may involve a change in direction of the light. Non-limiting examples of such optical elements include a refractive element (e.g., a lens), a reflective element (e.g., a mirrored surface, a light-scattering surface, etc.), a diffractive element (e.g., a Fresnel lens, a diffractive optic, etc.), and an optically-transmissive element (e.g., a transparent plate, a light pipe, etc.). Other types of optical elements are possible.
A mount 410 is coupled to the light source 402 and configured to selectively attach to and detach from a hat. The optically-transmissive element 404 is seated within a circumferential member 412 of the mount 410 and the light-emitting elements 406 are disposed adjacent ends 408 of the optically-transmissive element 404 on the circumferential member 412.
The mount 410, when attached to the hat, orients the light source 402 to project light onto an exterior surface of the hat.
Now turning back to
The apparatus 400 includes the battery receptacle 430, which is electrically-coupled to the light source 402 and has electrical contacts for coupling to one or more batteries. Electrical coupling of the battery receptacle 430 to the light source 402 may occur through an electrical circuit, which includes the electrical contacts of the battery receptacle 430. In some embodiments, the battery receptacle 430 allows the one or more batteries to be selectively inserted into and removed from the apparatus 400. For example, and without limitation, the battery receptacle 430 may include a detachable wall 432 covering an opening of a cavity (e.g., a slideable door). The detachable wall 432 facilitates removal of the one or more batteries from the apparatus 400 (e.g., for replacement or recharging).
In some embodiments, such as shown in
In many embodiments, the apparatus 400 includes a switch 434 configured to regulate a flow of electrical energy from the battery receptacle 430 to the light source 402. The switch 434 serves as part of the electrical circuit and regulates a voltage, a current, or both, received by the light source 402. In
During deployment, a user of the apparatus 400 attaches the mount 410 to the hat 420, which involves manipulating the pins 426 and clasps 428. To do so, the user presses the pins 426 through material of the hat 420, such as a layer of woven fabric or leather, thus puncturing the hat 420. Individual clasps 428 are then slipped over portions of individual shafts protruding through the hat 420. A friction fit between orifices of the clasps 428 and their respective shafts maintains coupling between each pair of pins 426 and clasps 428. In such coupling, the hat 420 has material sandwiched between each pair of pins 426 and clasps 428. After attachment of the mount 410, the user of the apparatus 400 may don the hat 420, becoming a wearer of the hat 420 with the apparatus 400 attached thereto.
Upon entering an area of little to no illumination, the user (or wearer) may choose to energize the light source 402. To energize the light source 402, the user actuates the switch 434 to the “on” state, thereby allowing electrical energy to flow from the battery receptacle 430 to the light source 402. In response, the light source 402 produces light. The user may adjust an intensity of light produced by the light source 402 by turning the rotary-dial switch 434. Light generated by the light-emitting elements 406 travels along the longitudinal axis of the optically-transmissive element 404, eventually exiting through the second surface 416 to illuminate the exterior surface of the hat 420.
While traversing the optically-transmissive element 404, light from the light-emitting elements 406 may be guided by internal reflection. But to exit through the second surface 416, such light must experience a change in direction. In embodiments having the plurality of light-scattering centers, light interacts with the plurality of light-scattering centers to change direction (i.e., to scatter). Moreover, in embodiments having the reflective element 418, light reaching the first surface 414 is redirected away from the mount 410. Such redirection occurs back into the optically-transmissive element 404, and due to a cross-sectional shape of the reflective element 418, is strongly biased towards the second surface 416. Scattering and redirection of light within the optically-transmissive element 404 may increase an intensity of light exiting the second surface 416, and may also improve a uniformity of exiting light along the longitudinal axis of the optically-transmissive element 404.
It will be appreciated that the light source 402 is particularly effective in creating a broad distribution of light from a light-emitting element 406 that produces highly-concentrated light, such as a light-emitting diode. As such, a lower number of light-emitting elements 406 may be used to illuminate the exterior surface of the hat 420, thus reducing a consumption of electrical energy from the one or more batteries. Such reduced consumption may increase an operational lifetime of the one or more batteries. Such reduced consumption may also decrease a frequency at which the one or more batteries need replacement or recharging.
When attached to the hat 420, the mount 410 orients the light source 402 such that light therefrom projects onto the exterior surface of the hat 420, and in particular, the band 422. Projection of light onto the exterior surface illuminates the hat 420, thereby improving its noticeability and that of the wearer. Projection of the light also highlights features such as decorative patterns, ornamental features, textures, reflective elements, text, logos, and so forth. In

In some embodiments, the apparatus 500 includes a switch 526 configured to regulate the first and second flows of electrical energy.

It will be understood that the mount 610, when attached to the hat, orients the plurality of first light sources 602 to project light onto an exterior surface of the hat and orients the second light source 652 to project light outward from the hat into an ambient environment thereof. Due to circumferential placement of the plurality of first light sources 602, the exterior surface includes a band encircling the hat. The second light source 652, by virtue of its front-side position, is operable to illuminate the ambient environment in front of the hat. Such illumination may improve a vision of a wearer under conditions of otherwise poor or no ambient lighting.
The plurality of first light sources 602 and the second light source 652 are electrically-coupled to a battery receptacle 620, such as via an electrical circuit. During operation, the electrical circuit may distribute separate flows of electrical energy to the plurality of first light sources 602 and second light source 652, i.e., a first flow of electrical energy to the plurality of first light sources 602 and a second flow of electrical energy to the second light source 652.

Now referring to
The hat 700 additionally includes a battery receptacle 706 electrically-coupled to the light source 704 and having electrical contacts for coupling to one or more batteries. Such electrical coupling may occur through an electrical circuit, which includes the electrical contacts of the battery receptacle 706. In some embodiments, the battery receptacle 706 is configured to selectively attach to and detach from the hat 700. In these embodiments, the battery receptacle 706 may be replaceable (e.g., due to damage, degraded batteries therein, etc.). In
The pair of electrical connectors 710, 712 includes a first electrical connector 710 configured to mate with a second electrical connector 712.
For recharging secondary batteries, the hat 700 may optionally include a charging circuit electrically-coupled to the battery receptacle 706 and configured to regulate at least one of a charging voltage and a charging current supplied thereto. The charging circuit may be capable of determining a state-of-charge of the secondary batteries, i.e., a percentage of full charge. Such determination may allow the charging circuit to cease supplying electrical energy to the secondary batteries when the state-of-charge reaches about 100%. In some embodiments, the charging circuit includes an indicator (e.g., a series of light-emitting diodes) or informational display (e.g., a liquid crystal display) to indicate the state-of-charge of the secondary batteries. The charging circuit may include a connector for coupling to an external power source, which in some embodiments, is integral to the battery receptacle 706. The connector may correspond to an outer (or “female”) connector.
The hat 700 further includes a mount 724 coupling the light source 704 to the hat 700 and configured to selectively attach to and detach from the hat 700. The mount 724 may be formed of any type of structural material including metals, plastics, ceramics, and composites. In some embodiments, such as shown in
The mount 724, when attached to the hat 700, orients the light source 704 to project light onto the exterior surface 702. The mount 724 controls a direction of illumination from the light source 704, which may involve controlling a position and orientation of individual light-emitting elements (and respective optical elements if present).
In
In many embodiments, the hat 700 includes a switch 742 configured to regulate a flow of electrical energy from the battery receptacle 706 to the light source 704. The switch 742 may be a binary-type switch capable of progressively cycling through an “off” state” for the light source 704, a first “on” state for the first plurality of light-emitting elements 734, a second “on” state for the second plurality of light-emitting elements 736, and back to the “off” state for the light source 704. For example, and without limitation, the first plurality of light-emitting elements 734 may have a broad-band emission of light (e.g., a white light) and the second plurality of light-emitting elements 736 may have a narrow-band emission of light (e.g., a green light). In this configuration, the switch 742 allows a user to selectively illuminate the hat 700 as desired (e.g., no light, white light, or green light). Such selective illumination may allow the user to communicate information to one or more observers in addition to improving the noticeability of the hat 700.
Although
The light source 804 is coupled to the hat 800 and configured to illuminate the exterior surface 802 upon receiving electrical energy. The light source 804 corresponds to a plurality of light sources 804 disposed around a perimeter of the hat 800. As such, the exterior surface 802 includes a band encircling the hat 800. Each of the plurality of light sources 804 may include one or more light-emitting elements and one or more optical elements. Such elements are analogous to the light-emitting elements and optical elements described in relation to
The hat 800 includes a battery receptacle 808 electrically-coupled to the plurality of light sources 804 and having electrical contacts for coupling to one or more batteries. Such electrical coupling may occur through an electrical circuit, which includes the electrical contacts of the battery receptacle 808 and may include conductive wiring (e.g., an electrical wiring harness, a flexible printed circuit board, etc.).

In some embodiments, such as shown in
In some embodiments, such as shown in
In some embodiments, the hat 800 includes a photosensor 818 configured to regulate the first flow of electrical energy, the second flow of electrical energy, or both, in response to an intensity of light measured in the ambient environment of the hat 800. The photosensor 818 may disposed at any position on the hat 800 capable of receiving light from the ambient environment. Accordingly, the hat 800 may include a plurality of photosensors 818. In
In embodiments having the plurality of photosensors 818, the flows of electrical energy may be altered in response to a controlling intensity of light. The controlling intensity of light may correspond to that measured by an individual photosensor or a plurality of photosensors. Non-limiting examples of the controlling intensity of light include a minimum intensity of light, a maximum intensity of light, and an average intensity of light. For example, and without limitation, the photosensor 818 on the left side may experience a temporary increase in ambient light conditions (e.g., light from headlights of an oncoming car). The photosensor 818 on the left side therefore measures an intensity of light higher than the photosensor 818 on the right side. If the controlling intensity corresponds to a maximum intensity of light, the photosensor 818 on the left side governs any alteration in the flow of electrical energy. Conversely, if the controlling intensity corresponds to a minimum intensity of light, the photosensor 818 on the right side governs any alteration in the flow of electrical energy. If the controlling intensity corresponds to an average intensity of light, both photosensors 818 govern the alteration of the flow of electrical energy, i.e., an average of the measured intensities of light is used in any alteration of the flow of electrical energy. It will be appreciated that the controlling intensity of light may allow the hat 800 to improve its noticeability despite different or changing light sources within the ambient environment.

In some embodiments, the battery receptacle 904 (or the electrical circuit 900) includes a pair of electrical connectors 912 for selectively attaching to and detaching from the electrical circuit 900.
In many embodiments, the electrical circuit 900 includes a switch 918 configured to regulate a flow of electrical energy from the battery receptacle 904 to the light source 902. The switch 918 is disposed on a segment 920 of the electrical circuit 900 between the battery receptacle 904 and the light source 902. The switch 918 may be a binary-type switch or a dimmer-type switch as described in relation to the switches 226, 322 of
In some embodiments, the light source 902 may require voltages, currents, or both different than those supplied by the battery receptacle 904. In these embodiments, a DC-to-DC power converter 922 may be optionally disposed on the segment 920 between the battery receptacle 904 and the switch 918. The DC-to-DC power converter 922 is operable to alter at least one of a voltage, a current, or both, supplied by the battery receptacle 904. Non-limiting examples of DC-to-DC power converter 922 include a step-up DC-DC regulator, a DC boost converter, a step-down DC-DC regulator, and a DC buck converter. In some embodiments, the DC-to-DC power converter 922 is integral to the battery receptacle 904.
In some embodiments, the electrical circuit 900 includes a photosensor 924 configured to measure an intensity of light in an ambient environment of the electrical circuit 900 and, in response, regulate the flow of electrical energy from the battery receptacle 904 to the light source 902. The ambient environment of the electrical circuit 900 may correspond to an ambient environment of an apparatus or hat as described in relation to
In some embodiments, the electrical circuit 900 includes a charging circuit 926 electrically-coupled to the battery receptacle 904 and configured to regulate at least one of a charging voltage and a charging current supplied thereto. The charging circuit 926 allows the electrical circuit 900 to recharge secondary batteries disposed in the battery receptacle 904. Electrical coupling between the charging circuit 926 and the battery receptacle 904 may involve a pair of electrical connectors 912, as shown in
In some embodiments, the charging circuit 926 is configured to be a DC circuit. In further embodiments, the electrical circuit 900 includes an external AC-to-DC power converter 932, such as a switching-mode power supply. The external AC-to-DC power converter 932 may be portable so that a user can easily transport and store the external AC-to-DC power converter 932. It will be appreciated that, by keeping circuitry associated with the external AC-to-DC power converter 932 separate from an upstream portion of the electrical circuit 900, the upstream portion may have a reduced volume, a lower weight, or both. As such, the upstream portion of the electrical circuit 900 may be more easily integrated into an apparatus or hat.
In some embodiments, a photovoltaic device 934 is electrically-coupled to the charging circuit 926. The photovoltaic device 934 is configured to receive light from the ambient environment of the electrical circuit 900 and convert such light into electrical energy. This electrical energy is supplied to the charging circuit 926 and may flow to at least one of the battery receptacle 904 or the light source 902. In some embodiments, a wireless charging device 936 is electrically coupled to the charging circuit. The wireless charging device 936 may be configured to receive electrical energy via magnetic coupling, capacitive coupling, or both. Such electrical energy is supplied to the charging circuit 926 and may flow to at least one of the battery receptacle 904 or the light source 902. It will be appreciated that the photovoltaic device 934 and the wireless charging device 936 may be used to recharge the one or more batteries 910 when such batteries are secondary batteries. Such recharging may postpone or eliminate a need to receive electrical energy from a direct source that is external to the electrical circuit 900.
The electrical circuit 900 may include other components for communicating with a user of an apparatus or a hat, an observer of the apparatus or the hat, other electronic devices or systems, or a combination thereof.
The control circuit 938 includes a processor 944 for sending electrical signals to a digital regulator 946. In many embodiments, the processor 944 includes a memory to assist in generating electrical signals. The digital regulator 946 controls a driving voltage, a driving current, or both, experienced by the light-emitting elements 906 of the light source 902. Such control may occur at a resolution that corresponds to individual light-emitting elements 906, groups of light-emitting elements 906, or the light source 902 as a whole.
During operation, the digital regulator 946 receives electrical signals from the processor 944, and in response, alters driving voltages, the driving currents, or both, for the light-emitting elements 906. Such alteration may allow the control circuit 938 to selectively increase or decrease an intensity of light produced by each light-emitting element 906, groups of light-emitting elements 906, or the light source 902 as a whole. The digital regulator 946 may have an electrical interface that matches an electrical configuration of the light-emitting elements 906 (e.g., a series electrical configuration, a parallel electrical configuration, or some combination thereof). Although the digital regulator 946 is depicted in
The photosensor 924 may operate collectively with the control circuit 938 to increase or decrease an intensity of light produced the light source 902. In
During operation, the photosensor 924 measures an intensity of light in the ambient environment of the electrical circuit 900 (or apparatus or hat), and in response, alters a voltage, a current, or both, on the second main segment 948. This alteration signals the processor 944 of the control circuit 938 to instruct the digital regulator 946 to alter the driving voltage, the driving current, or both, experienced by the light source 902 (or light-emitting elements 906). For example, and without limitation, the photosensor 924 may decrease a voltage on the second main segment 948, which signals the processor 944, in turn, to instruct the digital regulator 946 to decrease the driving current. The processor 944 thus assists the photosensor 924 in dynamically altering an illumination of the exterior surface of the hat in response to measurements of ambient light conditions.
It will be appreciated that the control circuit 938 and the digital regulator 946 may allow the light source 902 to produce patterns of light, such as flashing lights, changes in emitted color, and so forth. Such patterns may depend on a location, an orientation, a group affiliation, and an emission-type of the light-emitting elements 906. A specific pattern may be determined by the processor 944 based on signals received by the control circuit 938. Patterns of light may be used to communicate with a user of an apparatus or a hat, an observer of the apparatus or the hat, or both. For example, and without limitation, the electric circuit 900 may energize only a portion of the light-emitting elements 906 (i.e., a group) to indicate a state-of-charge of the one or more batteries 910 (e.g., a percent state of charge, impending depletion, etc.). In another non-limiting example, the electronic circuit 900 may include a “panic” button that, when activated, causes the light source 902 to change a color of light emitted therefrom (e.g., from green to red). Such change may alert an observer that the user requires immediate attention (e.g., due to injury). In yet another non-limiting example, the electronic circuit 900 may rapidly cycle an intensity of light on and off. Such cycling may be based on the user entering a controlled location (e.g., an area of operation for equipment) and alert an observer (e.g., an equipment operator) that the user is present in the controlled location. The observer may otherwise be unware of the user's presence.
In some embodiments, the control circuit 938 includes a wireless transceiver 950 electrically-coupled to the processor 944 and configured to convert wireless signals into electrical signals for the processor 944. The wireless signals may be any type of electromagnetic radiation capable of being received by or broadcast from an antenna. For example, and without limitation, the electromagnetic radiation may have one or more frequencies within a wavelength range from 1 kHz to 15 GHz. In some embodiments, the wireless signals conform to a wireless protocol, such as Bluetooth, IEEE 802.15.1, Wi-Fi, IEEE 802.11, WiGig™, Z-Wave, IEEE 802.15.4, and Zigbee protocols. However, other types of wireless protocols are possible. The wireless transceiver 950 may exchange wireless signals with any electronic device or system having a suitably-configured wireless transceiver. Non-limiting examples of such electronic devices or systems include mobile phones, tablets, laptops, desktop computers, base stations, routers, repeaters, gateways, and embedded controllers. It will be appreciated that the wireless signals may include information instructing the control circuit 938 to produce a pattern of light with the light source 902 (or light-emitting elements 906).
In some embodiments, the control circuit 938 includes a Global Positioning System receiver 952 (or GPS receiver) electrically-coupled to the processor 944. The GPS receiver 952 is configured to convert a GPS signal from a GPS satellite into electrical signals for the processor 944 that represent positional information, such as a latitude, a longitude, and an altitude of the GPS receiver 952. Other information may also be present, e.g., a time the GPS signal was sent, a name of the GPS satellite, an authentication of the GPS satellite, and so forth. The processor 944 may communicate such information via the wireless transceiver 950 to an electronic device or system, and in return, receive instructions to produce patterns of light. In some embodiments, the electrical circuit 900 also includes a speaker 954 (or buzzer). The speaker 954 (or buzzer) may allow audible information to be communicated to the user, which may also be heard by an observer. For example, if the user enters a controlled location, an audible warning may sound in addition to a pattern of light being produced. In some embodiments, the electrical circuit 900 includes a vibration motor 956. The vibration motor 956 may allow the electrical circuit 900 to alert the user using vibrations or patterns of vibrations (e.g., on-off sequences, alterations in vibration intensity, alterations in vibration frequency, etc.).
According to an illustrative embodiment, a method for improving the noticeability of a hat includes producing light from a light source coupled to the hat. The light source is configured to produce light upon receiving electrical energy. The method additionally includes orienting the light source such that light therefrom illuminates an exterior surface of the hat. The exterior surface may include a front-side exterior surface, a left-side exterior surface, a right-side exterior surface, a rear-side exterior surface, or any combination thereof. In some embodiments, the exterior surface includes at least one of a left-side exterior surface and a right-side exterior surface.
