An illuminating tilt-sensing golf ball having an illuminating component for emitting light at a predetermined frequency, a tilt sensor coupled to a control module, and upon the control module receiving a tilt detection signal, the control module being adapted to control the illuminating component to emit light at a second predetermined frequency if the tilt ball tilts more than a predetermined angle. The ball can also include a motion sensor, recording medium and transceiver for storing and transmitting motion sensor readings.
The embodiments described herein relate to illuminating and/or laser-emitting golf balls.
INTRODUCTIONFor each shot in a game of golf, a player strikes their golf ball with a golf club, with the ultimate goal of having their golf ball drop into a target golf hole in the lowest number of successive shots possible. Precise aiming is important to successful play. Golf balls often include alignment markings to help players aim their shots. Before taking a shot, a player may choose to reposition their ball so that the alignment markings point towards their intended target, particularly when training or when taking their first shot for a given hole. The player may then attempt to position their body and club square to the alignment markings, hopefully aligning their shot with their intended target.
The art teaches golf training devices with laser aiming means to provide improved aiming. The art teaches attaching a laser emitter to a golf club, such that the laser emitter points outwardly from the golf club, guiding a player's shot. Further, the art teaches golf training devices wherein laser emitters are housed in golf-ball-shaped enclosures. See for example, U.S. Pat. No. 6,871,250, U.S. Pat. No. 6,579,191, U.S. Patent Publication No. 2004/0137997 A1. In one embodiment, U.S. Pat. No. 6,872,150 teaches a putting practice kit comprising a laser golf ball having a laser emitter positioned within a central bore of the ball. In use, the player places the laser ball on a stand behind their play ball, and activates the laser ball such that it emits a planar laser beam over their play ball.
When training for golf, a player may wish to know whether or not they tend to hit their ball squarely, such that it rolls straight forward on a flat surface, or whether their ball spins or tilts to either side after being struck. The art teaches some embodiments of illuminated golf balls. See, for example, U.S. Pat. No. 6,257,995 B1. The art does not appear to teach golf balls which provide a means of alerting a player as to whether the ball they have hit has tilted after being hit.

In use, when preparing to strike the ball 100 before a golf shot, a user activates activation switch 114, causing laser emitter 108 to emit coherent light outwardly from the ball in an outwardly extending direction 104 through the transparent body 110. To line up their shot, the user (i.e. a golf player) can reposition the ball 100 on tee 125, or on the ground, so that the coherent light emitted along the outwardly extending direction 104, as well as the alignment stripe 116, both indicate the user's desired direction of travel for the ball. In the illustrated embodiment shown in
As shown more clearly in
In alternate embodiments, it is contemplated that the circumferential alignment stripe 116 (or the illuminated alignment stripe described below) is otherwise shaped and may not extend around the entire circumference of the ball. It is merely important that the alignment stripe provides a visual reference to the user to align their ball with an intended direction of travel for the ball along the target alignment plane.
In some embodiments, the ball's body is made so that the ball 100 emulates as closely as possible the characteristics of a regulation ball, i.e. the look and feel, as well as strength, weight (maximum of 45.93 g of mass), and flight characteristics of a regulation golf ball. In some alternate embodiments, the look and feel, mass, strength, weight and/or flight characteristics of the ball 100 do not all emulate a regulation ball.
A person of ordinary skill in the art will comprehend materials suitable for making the ball's body such that it emulates the characteristics of a regulation golf ball. In some embodiments the ball's body may be made of rubber, metal, iron, steel, polyurethane, ionomer resin and/or other materials known to those of skill in the art. In some embodiments, the ball's body comprises multiple layers of materials. For example, in some embodiments the ball's core may be made of a different material than the ball's outer shell. It will be understood that the ball's materials may also be selected to meet a particular application. For example, where the ball 100 is intended to be struck by a metal golf club, the ball may be at least partially made of material chosen to approximately match the properties of the driver's metal. Further, for example, where the ball is only intended to be used for training and it is not desired that the balls travels for a long distance when struck, the ball's body may be made of a lighter material.
In various embodiments described in more detail below, the ball body may comprise a variety of different sections alone or in combination, such as transparent body 110, light inhibiting section 124, transparent section 122, transparent section 138, partial transparent section 130. These different sections are described in more detail with respect to particular embodiments below. In the illustrated embodiment in
The at least partially transparent sections of the various embodiments of the ball's body, such as transparent body 110 in the illustrated embodiment of
In some alternate embodiments, the diameter 106 of the ball 100 may be larger than the diameter of a regulation golf ball. Regulation balls have a diameter of 1.680″ or larger, often approximately 1.680″. The increased diameter of the ball 100 may enhance the ball's usefulness as a training aid because it may encourage the user to swing through the ball, improving the user's aim. In some embodiments, the ball 100 may have a diameter 5% to 20%, and as much as 100%, larger than 1.680″.
In some embodiments, the ball 100 comprises dimples 113. Dimples 113 may be added to the ball where it is desired that the ball has the look, feel and flight characteristics of a regulation ball. Dimples may be arranged in different patterns on the surface of the ball, as known to those of skill in the art. Dimples have been omitted from
Light-emitting module 112 is positioned at least in part within the approximately spherical body of the ball. In the illustrated embodiment, light-emitting module 112 is positioned at least partly within transparent body 110. In some embodiments, light-emitting module 112 is positioned within a bore of the ball's body. In some embodiments the ball's body is shaped to receive the components of light-emitting module 112.
In most contemplated embodiments, the ball is balanced such that its center of gravity is centered. Balancing the ball involves a comparison of the mass and volume of the components of module 112, with the mass of the remaining volume of the ball surrounding the components of module 112 (for a given volume of the ball)—i.e. the ball's body, such that the weighted relative position of the distributed mass sums to zero at the center of the ball's approximately spherical body. Balancing the ball can be accomplished mathematically or using experimentation. Where the ball is balanced such that its center of gravity is centered, when it is struck it behaves similarly to a regulation golf ball.
In some embodiments, the laser emitter 108 is a laser diode outputting coherent light at a wavelength in the visible spectrum of light. In most embodiments the laser emitter 108 is a laser diode having an output wavelength of about 390 to 700 nm, typically in the range of 630 nm to 680 nm. A person of ordinary skill in the art would contemplate that other suitable emitters for emitting coherent light could be used. As conventionally known, laser diodes are electrically pumped semiconductor lasers which emit coherent light when current biased in the forward direction. Laser diodes are more rugged than equivalent gas lasers, and are well suited for use in articles that may experience sudden impacts from being bounced or shaken, such as a golf ball. In some embodiments laser emitter 108 comprises optical elements to provide increased beam coherence. In some embodiments, emitter 108 comprises a collimating lens, aperture and/or anamorphic prisms. In some embodiments, laser emitter 108 is connected in series with a load resistor which limits the current passing through the laser emitter. In some embodiments, the laser emitter 108 has an output power of between 1 mW to 5W. In some embodiments, the laser emitter 108 has an output power of between 3 mW to 25 mW. It will be understood that the laser emitter output power may be selected based on the desired operating condition. Where it is desired that coherent light output from the laser emitter 108 is visible during daylight, the output power may be selected to be higher than if it is only desired that coherent light output from the laser emitter is visible at night or otherwise where there is diminished ambient light where the ball is used.
Power module 102 comprises a power source, such as at least one battery cell (battery), for powering the components of module 112. In some embodiments power module 102 comprises at least one battery cell, suitable for placement in the ball 100 to power the components of module 112, such as laser emitter 108. It should be understood that a plurality of battery cells can be positioned in series to increase the voltage to the components of module 112, such as emitter 108. However, a plurality of batteries can be positioned in parallel to provide for longer battery life. Power module 102 preferably comprises two to four batteries, such as the CR 2325 series lithium batteries manufactured by Renata™ of Switzerland, connected in parallel. Without limitation, the preferred range of operation for the power source is between 1V and 12V DC. In some embodiments, the batteries are electrically connected to metal leads of laser emitter 108.
In some embodiments, the ball is only useful as a light-emitting ball for a single charge of power module 102, such that when power module 102 runs out of power, emitter 108 is no longer operable to emit coherent light.
In alternate embodiments the ball is adapted to allow the power source of power module 102—such as batteries—to be replaced or recharged. In such embodiments, the ball comprises an access port (not shown) providing access to the power source, such that the user can replace or recharge the power source. In embodiments where the power source is rechargeable, the access port may provide access to an electrical port electrically connected to the power source. In some embodiments, the access port comprises a bore in the ball's body with a suitable cover or plug. The cover or plug may be sized to fit into the bore, such that the access port is flush with the ball's surface when the cover or plug is inserted into the bore.
In some alternate embodiments, the power source in power module 102 can be recharged by placing the ball in a wireless recharging unit (not shown) that does not require a wired connection to the power module 102 to recharge the power source. In such embodiments, the ball and wireless recharging unit comprise hardware to provide wireless recharging when the ball is placed in the recharging unit. It will be understood that various embodiments of the recharging unit are contemplated. In some embodiments the wireless recharging unit charges the power module 102 via inductive charging. In such embodiments, the ball 100 and wireless recharging unit may comprise induction coils to permit inductive charging from the wireless recharging unit to at least one rechargeable battery in the power module.
The ball comprises an activation switch for activating light emission from the ball. In the illustrated embodiment, the ball comprises activation switch 114. As described in relation to other figures below, in some embodiments the ball may also or alternatively comprise motion activated switch 114′ and/or a wireless activation switch. In some embodiments, as illustrated in
As illustrated, in some embodiments activation switch 114 is located perpendicularly to the outwardly extending direction 104 at or near the surface of the ball. It is contemplated that activation switch 114 could be otherwise positioned. Positioning of the switch will depend on the type of switch used. For example, a touch-activated switch is positioned at or near the surface of the ball. In most embodiments, activation switch 114 is not located on the side of the ball opposite to the outwardly extending direction 104, because this may lead to damage to the activation switch when the ball is struck by the user.
In some embodiments, switch 114 is a membrane switch, flush with the outer surface of the ball when not depressed. In other embodiments, the switch is a capacitance touch switch, which can be activated by the body capacitance of a user. Other embodiments of the activation switch 114 are reasonably contemplated.
In some embodiments, visual or tactile indicia (not shown) are provided on the surface of the ball above the activation switch 114, so that the user can readily locate the activation switch 114. In some embodiments, the visual indicium is a coloured area on the ball's surface. In some embodiments, the visual indicium is text or an icon to make it clear to the user that it provides the location of the activation switch 114. In some embodiments, the tactile indicium is raised from the surface of the ball.

In the illustrated embodiment, the ball comprises transparent section 122. Transparent section 122 is made of similar materials as transparent body 110 and permits at least partial transmission of light therethrough. Transparent section 122 is aligned with emitter 108, such that when activated, emitter 108 emits coherent light through at least part of transparent section 122 in the outwardly extending direction 104. In some embodiments, as described above, transparent section 122 at least partially comprises a bore running through light-inhibiting section 124 to the emitter 108.

In use, as further described below, according to a particular embodiment, when the user activates the motion activation switch 114′ by shaking or striking the ball—such as by tapping the ball 100 against a club head—control module 128 controls the laser emitter 108 to emit coherent light for a predetermined period of time, and controls the illuminating component 126 to emit light outwardly through transparent body 110 for a second predetermined period of time.
In the illustrated embodiment, the ball 100 comprises at least one illuminating component 126 for emitting visible light outwardly from the ball through transparent body 110 at a predetermined frequency (i.e. colour), such that illuminating component 126 illuminates the ball. In some embodiments, illuminating component is at least one LED. It will be understood that in various embodiments, the illuminating component may be other types of activatable light emitters than LEDs. In some embodiments, the light emitting component may be a removable chemiluminescent light-emitter. As conventionally known, LEDs are semiconductor diodes that emit visible light when current biased in the forward direction. Unlike standard bulb type lamps, LEDs are immune to failure conditions such as filament breakage due to sudden shocks or bumps and are well suited for use in articles that may experience sudden impacts from being bounced or shaken such as a golf ball 100.
In addition LEDs are relatively energy efficient as they only require a relatively small amount of energy to generate significant amounts of light. For example, a typical incandescent lamp operates on 5 volts and uses a current of 115 milliamps while a LED can operate on 3 volts and draw current on the order of 5 milliamps. Accordingly, LEDs are a particularly desirable lighting source in applications involving small and lightweight devices where the desired size and weight limits the strength of power sources available thereby making energy efficiency important.
The LED(s) of illuminating component 126 may be a 5 mm high intensity wide dispersion LED. Since the rated lifetime of an LED is approximately 15 years, illuminating component 126 provides an extremely energy efficient, long lasting, light-weight and durable light source. In some embodiments, illuminating component 126 is connected in series with a load resistor which limits the current passing through the illuminating component.
Motion activation switch 114′ is a switch or sensor known to those of skill in the art, operable to activate components of the light-emitting module 112, specifically control module 128, when the ball is shaken vigorously, struck or bounced (referred to hereafter as “motion-triggered”). In various embodiments, when the ball is motion-triggered, activation switch 114′ is activated, activating control module 128, and control module sleep timer 170. In some embodiments, activation switch 114′ comprises an element for generating electricity from kinetic energy imparted to the ball 100—such as a piezoelectric element—which then activates a switch to activate control module 128. In other embodiments, activation switch 114′ comprises a spring switch, wherein when the ball is bounced or shaken, a spring comes into contact with a lead, closing the switch. In some embodiments, motion activation switch 114′ is calibrated so that it will only activate when the ball's acceleration exceeds a certain threshold, such as 0.5 m/s2. In some embodiments, the motion activation switch 114′ is calibrated so that it will activate when the ball is tapped against a user's putter. This avoids unintentional activation during handling.
Control module 128 controls illuminating component 126, emitter 108 and other components of the light-emitting module 112 in various embodiments. Control module 128 may comprise a hardware controller containing logic circuitry that controls the output of emitter 108 and illuminating component 126. The control module 128 may comprise a processor, an ASIC, a hardware controller and the like, which can be programmed or otherwise configured to provide control signals to control components of light-emitting module 112. The control module 128 may be provided with software instructions to implement certain functionality. Accordingly, the control module 128 may be provided with software instructions to implement certain functionality depending on its implementation.
When activated by switch 114′, control module 128 activates emitter 108 and illuminating component 126 for a first predetermined time and a second predetermined time, respectively. In an example embodiment, control module 128 activates emitter 108 for fifteen seconds and activates illuminating component for fifteen minutes after the activation switch 114′ is activated.
Though the functionality of control module 128 was described above in relation to activation switch 114′, the inventor contemplates that the same functionality and timed activation of the emitters is achieved with alternate or additional activation switches. Accordingly, in some embodiments, the ball comprises activation switch 114, and control module 128 activates emitter 108 and illuminating component 126 for a first and second predetermined time when switch 114 is activated.
In some alternate embodiments, the ball 100 comprises one of emitter 108 or illuminating component 126.
Alternately, in some embodiments, the ball 100 comprises an activation switch 114 and an activation switch 114′, and each switch is connected to one of the illuminating component 126 or the laser emitter 108. In some embodiments comprising both switch 114 and 114′, the laser emitter 108 may be coupled to the activation switch 114, such that the laser emitter is only activated when the activation switch 114 is depressed, and the illuminating component 126 may be coupled to the activation switch 114′, such that the illuminating component 126 is only initially activated when the activation switch 114′ is activated.
In alternate embodiments, a wireless activation switch (not shown) may be used instead of or in addition to motion activate switch 114′ and/or switch 114. In such embodiments, the wireless activation switch is operable to activate components of the light-emitting module 112, specifically the control module 128, in response to a wireless activation signal. The wireless activation signal may be sent, for example, from a wireless communication device or a remote. The wireless communication device or remote could be configured with hardware controller circuitry and components, such as a transceiver operable to output a wireless activation signal to activate the ball. It will be understood that in such embodiments control module 128 may comprise a hardware controller containing logic circuitry that controls the output of emitter 108 and/or illuminating component 126 in response to receiving a wireless activation signal. The control module 128 may comprise a processor, an ASIC, a hardware controller and the like, which can be programmed or otherwise configured to provide control signals to control components of light-emitting module 112 in response to wireless activation signals. The control module 128 may further comprise a transceiver to receive wireless activation signals.
In alternate embodiments, the ball comprises activation switch 114′, power module 102, and comprises emitter 108 and/or illuminating component 126; and, activation switch 114′ is operable to selectively activate the power emitter 108 and/or illuminating component 126, without first activating control module 128. In such embodiments, control module 128 may not be included in the ball. In such embodiments, when the ball is motion-triggered, activation switch 114′ is activated, activating emitter 108 and/or illuminating component 126. In such embodiments, the emitter 108 and/or illuminating component 126 may remain activated until the ball is motion-triggered again. In some embodiments, the activation switch 114′ is calibrated such that if the ball is motion-triggered with an acceleration that is too high or too low—the activation switch will not be activated. Accordingly, the activation switch 114′ may be calibrated so that only a specific user action within a given threshold would activate activation switch 114′—such as tapping the ball against a user's putter. This would prevent accidental activation during regular handling, and also may prevent deactivation when the ball is struck by a golf club. Accordingly, in some embodiments, the activation switch 114′ is only activated when the ball is motion-triggered resulting in acceleration above a certain amount, and in some cases below a certain amount.
In alternate embodiments, wireless activation switch or activation switch 114 are operable to selectively activate the power emitter 108 and/or illuminating component 126 without first activating control module 128, as described above.

In use, in the illustrated embodiment, when the user activates activation switch 114, control module 128 controls the laser emitter 108 to emit coherent light in the outwardly extending direction 104 for a predetermined period of time, and control module 128 controls the illuminating component 126 to emit light outwardly through transparent section 138 for a second predetermined time at a predetermined frequency (i.e. colour). Further, the control module 128 activates tilt sensor 134 and motion sensor 132. When illuminating component 126 is illuminated, if tilt sensor 134 senses that the ball tilts such that the target alignment plane has tilted more than a predetermined angle from vertical, the control module 128 controls the illuminating component 126 to emit light at a second predetermined frequency (i.e. the light emitted from the illuminated component 126 changes colour). In some embodiments, when illuminating component 126 is illuminated, if motion sensor 132 detects that the ball has stopped moving, the control module 128 deactivates the illuminating component 126 and other active components of light-emitting module 112 after a predetermined time.
In the illustrated embodiment, ball 100 comprises a light-inhibiting section 124 and a transparent section 138 coplanar with the outwardly extending direction 104. When illuminating component 126 is illuminated, transparent section 138 provides an illuminated circumferential alignment stripe coplanar with the outwardly extending direction 104 (i.e. coplanar with the target alignment plane).
It is contemplated that various embodiments of the ball 100 that comprise both an illuminating component 126 and a light-inhibiting section 124 could have a transparent section 138 coplanar to the outwardly extending direction 104 for providing an illuminating alignment stripe. In some embodiments, further described below in relation to
Motion sensor 132 comprises at least one sensor for sensing motion of ball 100 and outputting a digital or analog signal indicative of the sensed motion. The output signal is a motion sensor reading. When active, motion sensor 132 generates motion sensor readings and outputs them to control module 128. In some embodiments, motion sensor 132 comprises at least one accelerometer for measuring acceleration. In some embodiments, a plurality of accelerometers or a single multiple-axis accelerometer is mounted in order to sense motion along multiple axes, such as two or three axes, representing two or three dimensions.
As described above, control module 128 activates illuminating component 126 when activation switch 114 is activated. In some embodiments, when control module 128 receives signals from motion sensor 132 indicating that the ball has come to a rest, control module 128 disables the illuminating component 126 and laser emitter 108 (if it is still active) after a predetermined time. In some embodiments, the control module 128 disables the illuminating component 126 and laser emitter 108 immediately after the ball comes to a rest. In some embodiments, the motion sensor readings may indicate that the ball has come to a rest after they stop changing in amplitude for a predetermined period of time.
Tilt sensor 134 comprises a sensor mounted to sense if the target alignment plane tilts more than a predetermined angle from vertical, where vertical is defined as the direction of gravity. It will be understood that a multitude of different sensors operable to detect tilting are contemplated. In some embodiments, the tilt sensor 134 comprises at least one accelerometer. In some embodiments, when active, tilt sensor 134 outputs tilt sensor readings to control module 128. In some embodiments, tilt sensor readings indicate how much the target alignment plane has tilted from vertical.
As described above, control module 128 activates illuminating component 126 to emit light at a predetermined frequency (i.e. colour) when activation switch 114 is activated. If the control module 128 receives a tilt sensor reading that indicates that the ball has tilted such that the target alignment plane is more than a predetermined degree from vertical, control module 128 controls illuminating component 126 to emit light at a second predetermined frequency (i.e. a second colour). Accordingly, if tilt sensor 134 detects that the ball has tilted more than a predetermined angle, control module 128 controls illuminating component 126 to emit light of a different colour. In some embodiments, if tilt sensor 134 detects that the ball has tilted more than a predetermined angle, the illuminating component 126 emits red light.
In an alternate embodiment, the control module 128 only receives a tilt sensor reading from tilt sensor 134 when the sensor detects that the ball has tilted beyond a predetermined angle. Accordingly, the control module 128 controls illuminating component 126 to emit light at a second predetermined frequency if it detects a tilt sensor reading. In such embodiments, for example, tilt sensor 134 may be, for example, a rolling ball tilt sensor.
It will be understood that in order for control module 128 to analyze motion sensor readings or tilt sensor readings to determine if the ball has come to a rest or has tilted from the vertical, the control module 128 may comprise a processor, memory, an ASIC, application program instructions and the like, which can be programmed or otherwise configured to interpret motion sensor readings and tilt sensor readings.

In the illustrated embodiment, light-emitting module 112 comprises motion sensor 132 for outputting motion sensor readings, a recording medium 136 for receiving and storing motion sensor readings and a transceiver 133 for outputting motion readings to a user device (not shown). Motion sensor 132, recording medium 136 and transceiver 133 are electrically connected to control module 128.
In the illustrated embodiment, control module 128 comprises circuitry, hardware and software instructions for communicating with nearby a user device. For example, control module 128 may comprise a processor, an ASIC, a hardware controller and the like, which can be programmed or otherwise configured to provide control signals and communicate with a user device. The control module 128 may be provided with software instructions to implement the specified functionality. In some embodiments, the processor receives motion sensor readings, analyzes them in conjunction with the stored software instructions and writes them to the recording medium 136. Further, the processor processes software instructions to allow communication with a user device using transceiver 133.
In use, when activation switch 114′ is activated, control module 128 activates motion sensor 132, recording medium 136 and transceiver 133. When activated, motion sensor 132 outputs motion sensor readings to control module 128. Control module 128 writes motion sensor readings to recording medium 136 for storage. In some embodiments, a user can retrieve the motion sensor readings from control module 128 after pairing a user device with control module 128 by sending a request from a paired user device to control module 128. Transceiver 133 allows for wireless communication between control module 128 and user device. In some embodiments, control module 128 also records tilt sensor readings to recording medium 136 and can communicate tilt sensor readings to a user device.
The embodiment of light-emitting ball 100 illustrated in
In alternate embodiments, the transparent sections (130, 138, 122) can be otherwise shaped. Further, more than one transparent section may be included having different shapes—such as arrows or a plurality of parallel transparent sections. It will be understood that it is merely important that an included transparent section provides a visual reference that can be illuminated by illuminating component 126 for use by a user in aligning the ball with an intended direction of travel for the ball—i.e. providing an illuminated alignment stripe. Accordingly, the transparent section provides a visual reference along the target alignment plane. Additionally, where a laser emitter 108 is included, at least a transparent section is disposed to allow transmission of coherent light from the laser emitter along the outwardly extending direction 104.

In some embodiments, mounting core 142 comprises mounting supports 140, 140′ for mounting the components of module 112 in the ball. Mounting supports 140, 140′ comprise means of mounting the components of module 112 at least partially within the mounting core 142. It will be understood that as many mounting supports as needed may be included in mounting core. In some embodiments the mounting supports may be rigid, in order to rigidly support the components of module 112. In some embodiments the mounting supports 140, 140′ may be flexible, such that the mounting supports flex when the ball compresses after impact with a club. In some embodiments, the mounting supports 140 may be hardening foam, adhesive or mechanical mounting means.
In alternate embodiments, mounting supports 140, 140′ may be used to mount the components of module 112 within the ball 100 even if the ball 100 does not comprise a discrete mounting core 142.

It will be understood that in the various embodiments of the invention described below (or above) activation switch 114 can be replaced or supplemented by motion activation switch 114′ and/or a wireless activation switch.
When activation switch 114 is activated, the control module 128 is activated, and the control module 128 activates emitter 108, illuminating component 126 and starts a sleep timer 170. In some embodiments, the emitter 108 is only activated while the activation switch 114 is depressed. In other embodiments, control module 128 activates emitter 108 for a first predetermined time when activation switch 114 is activated. In some embodiments, the first predetermined time is five seconds to fifteen minutes, particularly five seconds to sixty seconds, such that the user has time to align their shot while emitter 108 remains active.
Control module 128 activates illuminating component 126 for a second predetermined time after the activation switch 114 is activated. In some embodiments, the second predetermined time is ten seconds to eight hours, and in particular about 15 minutes. The second predetermined time may be longer than 15 minutes, for example, where it is desired that the illuminated component remains illuminated for an entire round of golf. The second predetermined time is shorter when the ball is only intended to remain illuminated for the length of a single shot. The control module 128 receives timing signals from timer 170 to determine whether the predetermined times have elapsed.
In some embodiments, it is contemplated that the light-emitting module 112 as illustrated in
In the illustrated embodiment, the functionality of light-emitting module 112 is similar to the embodiment described above in relation to
While illuminating component is illuminated, if tilt sensor 134 senses that the ball tilts such that the target alignment plane tilts more than a predetermined angle from vertical, the control module 128 controls the illuminating component to emit light at a second predetermined frequency. In some embodiments, the light emitted at the second predetermined frequency is red light. Accordingly, while the illuminating component 126 is active, if the tilt sensor 134 detects that the ball tilts more than a predetermined angle, the illuminated component emits a different colour of light. In some embodiments, the predetermined angle is between five to ninety degrees and in particular forty-five degrees.
In the illustrated embodiment, when activation switch 114 is activated, the control module 128 activates motion sensor 132, recording medium 136 and transceiver 133 for a predetermined time or until motion sensor 132 stops sensing motion.
While motion sensor 132 is activated it takes motion sensor readings and outputs them to control module 128. As discussed above in relation to
In some embodiments comprising a motion sensor 132, as in
It will be appreciated that while the light-emitting module 112 has been described in the context of a golf ball in order to provide an application-specific illustration, it should be understood that the light-emitting module 112 could also be applied to any other sports balls, which would benefit from illuminating, such as tennis balls or soccer balls.
In alternate embodiments, the components of module 112 are positioned at or near the surface of the light-emitting ball instead of near its center, such that the body of the ball would not need to have transparent sections or bores in line with the laser emitter 108 or illuminating component 126 to permit emission of light outwardly from the ball. The ball would still have to be balanced such that its center of gravity is at its center.
It will be appreciated that the illustrated embodiments shown to provide some example embodiments of the invention. The invention is not limited to the above-described embodiments, but contemplates reasonable variations therefrom. Various combinations of the illustrated embodiments and elements are contemplated. For example, in some embodiments the light-emitting ball has an illuminating component and/or a laser emitter, and may have a transparent body or may have a light-inhibiting body with appropriate transparent sections. Further, in the various embodiments the transparent sections can extend circumferentially such that the ball has an illuminated circumferential alignment stripe, or may extend only partially around the circumference of the ball, such that the ball has a partial circumferential alignment stripe. Further, any of the embodiments can have a motion sensor, recording medium and transceiver. Further, it will be understood that electrical and mechanical connections and couplings described above are described for illustration only. Other electrical and mechanical connections and couplings are contemplated to achieve the desired functionality.
Numerous specific details are set forth herein in order to provide a thorough understanding of the example embodiments described herein. However, it will be understood by those of ordinary skill in the art that these embodiments may be practiced without these specific details. In other instances, well-known methods, procedures and components have not been described in detail so as not to obscure the description of the embodiments. Furthermore, this description is not to be considered as limiting the scope of these embodiments in any way, but rather as merely describing the implementation of these various embodiments.
