BACKGROUNDRecent consumer interest in personal health has led to a variety of personal health monitoring devices being offered on the market. Such devices, until recently, tended to be complicate to use and were typically designed for use with one activity, e.g., bicycle trip computers.
Recent advances in sensor, electronics, and power source miniaturization have allowed the size of personal health monitoring devices, also referred to herein as “biometric tracking” or “biometric monitoring” devices, to be shrunk to extremely small sizes. For example, the Fitbit Ultra is a biometric tracking device that is approximately 2″ long, 0.75″ wide, and 0.5″ deep; it has a display, battery, sensors, wireless communications capability, power source, and interface button, as well as an integrated clip, packaged within this small volume.

In some implementations, a band configured to be worn on a person's limb may be provided. The band may include a pocket region having a pocket. The pocket may be formed between a first layer of flexible material and a second layer of flexible material and sized to allow a biometric tracking device associated with the band to be fully inserted within the pocket. The band may also include a slit in an exterior textile layer of the band. The slit may extend in a direction substantially parallel to the person's limb when the band is worn on the person's limb, may be shorter in length than a longest dimension of the associated biometric tracking device, and may permit the biometric tracking device to be fully inserted into the pocket.

In some implementations, the band may also include a first end and a second end, the first end located opposite the second end. The pocket region may be located between the first end and the second end.
In some implementations the band may include a torsional flat spring element spanning between the first end and the second end. The torsional flat spring element may have a first mechanically stable configuration that causes the band to maintain a circular shape.
In some implementations, the torsional flat spring element may be mechanically bistable and may have a second mechanically stable configuration that causes the band to maintain a substantially flat shape.
In some implementations, the band may also include a first fastening region adjacent to the first end and a second fastening region adjacent to the second end and configured to engage with at least a portion of the first fastening region in a disengageable manner to allow the band to be placed around the person's limb and the first end and the second end to be connected to one another.

In some implementations, the exterior textile layer may have an opening substantially corresponding in size to the pocket, and the first layer of flexible material may be interposed between the exterior textile layer and the second layer of flexible material.

In some implementations, the wearable case may further include a lanyard threaded through the hole, the lanyard sized so as to be wearable around a person's neck. In some other implementations of the wearable case, the wearable case may also include a keyring threaded through the hole. In some implementations, the compliant material may have a Young's modulus between about 1 MPa and 690 MPa. In some implementations, the compliant material may be a thermoplastic polyurethane, a thermoplastic elastomer, a thermoplastic vulcanizate, a polyurethane, a silicone, or a combination thereof.
These and other implementations are described in further detail with reference to the Figures and the detailed description below.
The various implementations disclosed herein are illustrated by way of example, and not by way of limitation, in the figures of the accompanying drawings, in which like reference numerals refer to similar elements.
The present disclosure relates to wearable biometric monitoring devices (also referred to herein as “biometric tracking devices” or “biometric tracking modules”) such as those, for example, illustrated in
The portable biometric monitoring device (also referred to herein as “the device”) may collect one or more types of biometric data, e.g., data pertaining to physical characteristics of the human body (such as heartbeat, perspiration levels, etc.) and/or data relating to the physical interaction of that body with the environment (such as accelerometer readings, gyroscope readings, etc.), from the one or more biometric sensors 110 and/or external devices (such as an external heart rate monitor, e.g., a chest-strap heart rate monitor) and may then store such information for later use, e.g., for communication to another device via the I/O 112, e.g., a smartphone or to a server over a wide-area network such as the Internet. The processing unit 106 may also perform an analysis on the stored data and may initiate various actions depending on the analysis. For example, the processing unit 106 may determine that the data stored in the memory 108 indicates that a goal threshold has been reached and may then display content on a display of the portable biometric tracking device celebrating the achievement of the goal. The display may be part of the operator interface 104 (as may be a button or other control, not pictured, that may be used to control a functional aspect of the portable biometric monitoring device).
In general, biometric monitoring device may incorporate one or more types of user interfaces including but not limited to visual, auditory, touch/vibration, or combinations thereof. The biometric monitoring device may, for example, display the state of one or more of the data types available and/or being tracked by the biometric monitoring device through, for example, a graphical display or through the intensity and/or color of one or more LEDs. The user interface may also be used to display data from other devices or internet sources. The device may also provide haptic feedback through, for instance, the vibration of a motor or a change in texture or shape of the device. In some implementations, the biometric sensors themselves may be used as part of the user interface, e.g., accelerometer sensors may be used to detect when a person taps the housing of the biometric monitoring unit with a finger or other object and may then interpret such data as a user input for the purposes of controlling the biometric monitoring device. For example, double-tapping the housing of the biometric monitoring device may be recognized by the biometric monitoring device as a user input that will cause the display of the biometric monitoring device to turn on from an off state or that will cause the biometric monitoring device to transition between different monitoring states, e.g., from a state where the biometric monitoring device may interpret data according to rules established for an “active” person to a state where the biometric monitoring device may interpret data according to rules established for a “sleeping” person.
In another example, while the user is wearing the biometric monitoring device 102, the biometric monitoring device 102 may calculate and store a user's step count while the user is wearing the biometric monitoring device 102 and then subsequently transmit data representative of step count to the user's account on a web service like www.fitbit.com, to a mobile phone paired with the portable biometric monitoring unit, and/or to a standalone computer where the data may be stored, processed, and visualized by the user. Indeed, the device may measure, calculate, or use a plurality of other physiological metrics in addition to, or in place of, the user's step count. These include, but are not limited to, caloric energy expenditure, floors climbed or descended, heart rate, heart rate variability, heart rate recovery, location and/or heading (e.g., through GPS), elevation, ambulatory speed and/or distance traveled, swimming lap count, bicycle distance and/or speed, blood pressure, blood glucose, skin conduction, skin and/or body temperature, electromyography data, electroencephalographic data, weight, body fat, and respiration rate. Some of this data may be provided to the biometric monitoring device from an external source, e.g., the user may input their height, weight, and stride in a user profile on a fitness-tracking website and such information may then be communicated to the biometric tracking device and used to evaluate, in tandem with data measured by the biometric sensors 110, the distance traveled or calories burned of the user. The device may also measure or calculate metrics related to the environment around the user such as barometric pressure, weather conditions, light exposure, noise exposure, and magnetic field.
As mentioned previously, collected data from the biometric monitoring device may be communicated to external devices through the communications interface. The communications interface may include wireless communication functionality so that when the biometric monitoring device comes within range of a wireless base station or access point, the stored data automatically uploads to an Internet-viewable source such as a website, e.g., www.fitbit.com. The wireless communications functionality may be provided using one or more communications technologies known in the art, e.g., Bluetooth, RFID, Near-Field Communications (NFC), Zigbee, Ant, optical data transmission, etc. The biometric monitoring device may also contain wired communication capability, e.g., USB.
Other implementations regarding the use of short range wireless communication are described in U.S. patent application Ser. No. 13/785,904, titled “Near Field Communication System, and Method of Operating Same” filed Mar. 5, 2013 which is hereby incorporated herein by reference in its entirety.
It is to be understood that
Moreover, it is to be understood that in addition to storing program code for execution by the processing unit to effect the various methods and techniques of the implementations described herein, the memory 108 may also store configuration data or other information used during the execution of various programs or instruction sets or used to configure the biometric monitoring device. It is to be further understood that the processing unit may be implemented by a general or special purpose processor (or set of processing cores) and thus may execute sequences of programmed instructions to effectuate the various operations associated with sensor device syncing, as well as interaction with a user, system operator or other system components. In some implementations, the processing unit may be an application-specific integrated circuit.
Though not shown, numerous other functional blocks may be provided as part of the biometric monitoring device 102 according to other functions it may be required to perform, e.g., environmental sensing functionality, etc. Other functional blocks may provide wireless telephony operations with respect to a smartphone and/or wireless network access to a mobile computing device, e.g., a smartphone, tablet computer, laptop computer, etc. The functional blocks of the biometric tracking device 102 are depicted as being coupled by the communication path 114 which may include any number of shared or dedicated buses or signaling links. More generally, however, the functional blocks shown may be interconnected using a variety of different architectures and may be implemented using a variety of different underlying technologies and architectures. With regard to the memory architecture, for example, multiple different classes of storage may be provided within the memory 108 to store different classes of data. For example, the memory 108 may include non-volatile storage media such as fixed or removable magnetic, optical, or semiconductor-based media to store executable code and related data and/or volatile storage media such as static or dynamic RAM to store more transient information and other variable data.
The various methods and techniques disclosed herein may be implemented through execution of one or more a sequences of instructions, e.g., software programs, by the processing unit 106 or by a custom-built hardware ASIC (application-specific integrated circuit) or programmed into a programmable hardware device such as an FPGA (field-programmable gate array), or any combination thereof within or external to the processing unit 106.
Further implementations and implementations of portable biometric monitoring devices can be found in U.S. patent application Ser. No. 13/156,304, titled “Portable Biometric Monitoring Devices and Methods of Operating Same” filed Jun. 8, 2011, which is hereby incorporated herein by reference in its entirety.
In some implementations, the biometric monitoring device may include computer-executable instructions for controlling one or more processors of the biometric monitoring device to obtain biometric data from one or more biometric sensors. The instructions may also control the one or more processors to receive a request, e.g., an input from a button or touch interface on the biometric monitoring device, a particular pattern of biometric sensor data (e.g., a double-tap reading), etc., to display an aspect of the obtained biometric data on a display of the biometric monitoring device. The aspect may be a numerical quantity, a graphic, or simply an indicator (a goal progress indicator, for example). In some implementations, the display may be an illuminable display so as to be visible when displaying data but otherwise invisible to a casual observer. The instructions may also cause the one or more processors to cause the display to turn on from an off state in order to display the aspect of the biometric data.
The depicted biometric monitoring device in
The biometric monitoring device 202 may include a PCB 228, a battery 232, and various other components that are housed within the front housing 222 and the back housing 224. Among these other components may be one or more biometric sensors selected from a variety of different types of biometric sensors, e.g., accelerometers, gyroscopes, etc. One type of biometric sensor that may be included is a barometric altimeter. In order to allow such a barometric altimeter to measure ambient atmospheric conditions while preventing liquid, e.g., rain or sweat, from entering and damaging electronics in the interior of a portable biometric monitoring device, a gas permeable, liquid-impermeable (or liquid-resistant) membrane such as a Gore™ vent may be used. Such a membrane may be placed over a hole in the device body, allowing the pressure from the exterior of the case to equalize with the pressure sensor on the interior.
Alternatively, or in addition, to the use of a Gore™ vent, a gasket 234 located in the interior of the biometric monitoring device may be used. In one implementation, the barometric altimeter/pressure sensor may be mounted to the PCB 228. A thin, flexible water impermeable membrane may cover the barometric altimeter/pressure sensor in a manner that allows the barometric altimeter/pressure sensor to still detect the local pressure on the opposite side of the membrane while preventing any water or moisture that may be present from crossing over the membrane. The membrane may, for example, be adhered to the PCB 228. Other features of the biometric monitoring device, e.g., altimeter gasket 234, may seal against the membrane and front housing 222 or the back housing 224 when the biometric monitoring device is fully assembled to create a water-tight pressure measurement chamber that is sealed off from the electronics of the biometric monitoring device but that nonetheless permits pressure measurements of the conditions within the pressure measurement chamber by the barometric altimeter/pressure sensor through the membrane. Such a feature may prevent water or other liquids from entering the biometric monitoring device except within the pressure measurement volume bounded by the altimeter gasket 234, membrane, and interior surface of the front housing 222 or the back housing 224 (or other housing equivalent). Such a segregated pressure measurement volume may also prevent pressure changes from the interior of the biometric monitoring device from being detected by the barometric altimeter/pressure sensor. For example, if deformation of the biometric monitoring device case causes a pressure change within the housing, isolating the pressure sensor from the rest of the biometric monitoring device housing may eliminate or reduce the pressure change detected by the barometric altimeter/pressure sensor due to such deformation.
The biometric monitoring device of
In
In the implementation shown, e.g., in
The biometric monitoring device 402 shown in
Biometric monitoring devices and cases such as those discussed above may be designed to allow the biometric monitoring device to be easily attached/inserted and removed from any of a suite of different wearable attachments. The biometric monitoring device may be attached to all of the cases using the same attachment method or through different attachment methods for one or more different cases. Additionally, a combination of attachment methods may be used to create a more secure connection of the biometric monitoring device to the case.
In one example of an additional attachment technique, the biometric monitoring device may be secured to the case though the use of a permanent magnet or electromagnet. There may be a magnet in the device and the case may contain a ferrous metal. Alternatively, the case may contain a permanent magnet while the device or device body contains ferrous metal. In another example, the case and the device may both contain magnets. In such a case, the magnets may be installed to force the device to be secured to the case with a specific orientation due to the force created by the interaction of the two magnets. Permanent magnets or electromagnets may be used in place of or in addition to mechanical retention techniques.
A clip case 544 may allow the biometric monitoring device 502 to be clipped to a belt, pocket, or other portion of a wearer's clothing. If the biometric monitoring device 502 is inserted into a keychain case 546, the keychain case 546/biometric monitoring device 502 may be used to carry the wearer's keys, or may be securely clipped to a belt loop, zipper pull, or other feature of the wearer's clothing. A necklace case 548 may allow the biometric monitoring device 502 to be worn around the wearer's neck as a pendant. In some implementations, the pendant of the necklace case 548 and the fob of the keychain case 546 may be provided by the same structure, i.e., the “ring” of the keychain may be exchanged for the “chain” or “lanyard” of the necklace without removing the biometric monitoring device 502 from the pendant/fob structure.
Each of the clip case 544, the keychain case 546, and the necklace case 548 may be constructed out of one or more materials including but not limited to metals and/or flexible/compliant viscoelastic materials. Flexible compliant viscoelastic materials (herein referred to as viscoelastics) may include, but are not limited to thermoset elastomers (rubber), thermoplastic elastomers (TPE), thermoplastic vulcanizates, silicones, and/or polyurethanes (including thermoplastic polyurethanes (TPU)). For example, the bulk of such cases may be made from a viscoelastic material and may be formed around a metal or other more rigid material that forms a semi-rigid structural backbone or that may be used to provide additional stiffness for components that require it, e.g., for the clip on a clip case. Generally speaking, flexible materials suitable for manufacturing a clip case, a keychain case, a necklace case, or a wristband case may include materials having elastic moduli of 15 to 60 MPa, 3.6 to 120 MPa, 69 to 690 MPa, 1 to 50 MPa, or combinations of such elastic moduli.
In addition to the viscoelastic cases represented by the clip case 544, the keychain case 546, and the necklace case 548, another type of case that is envisioned is a textile-based wristband case 550. Such a textile-based wristband case 550 is also discussed in further detail later in this disclosure.
Returning to the clip case 544, the keychain case 546, and the necklace case 548, certain observations may be made. The biometric monitoring device 502 may have a generally smooth and rounded exterior that permits it to be easily slid into a silicone or other flexible viscoelastic case, e.g., such as the clip case 544, the keychain case 546, and/or the necklace case 548. Each such case may be designed and constructed so as to balance the degree of retention of the device with the ability of a wearer to easily remove and reinsert the biometric monitoring device 502 into the case. The biometric monitoring device may be inserted into an opening in the viscoelastic material of the case that is smaller than one or more dimensions of the device, e.g., smaller than a maximum dimension of the biometric monitoring device (as measured along a diagonal or along one of three mutually-orthogonal axes aligned with standard top/front/side views of the biometric monitoring device 502). By stretching the viscoelastic opening, the opening can be expanded enough to allow the biometric monitoring device 502 to be inserted into the case. The elasticity of the viscoelastic causes it to return to its original size, preventing the device from accidentally falling out of the case.
For example,
In some implementations, the opening in the viscoelastic material of the case may also act as a window to the display of the device (as seen in
In some implementations, one or more channels, tubes, and/or holes may connect the pressure sensor of the device to the exterior of the case as seen with ventilation holes 652 in
In another implementation, the case may be designed to transfer pressure from the exterior of the case to a pressure sensor in the device through the use of a pressure-transmissive membrane or material. In another example, a window in the case could be used to allow optical light sources and sensors to interact with the environment outside of the case effectively. In yet another implementation, the viscoelastic of the case may be transparent either in one area, multiple areas, or everywhere so as to allow visual indicators or displays to be seen through the case and/or to give optical sensors an optical path to the exterior of the case. Case transparency may be achieved by making or more areas of the case thin (for example by molding). Thin case areas made out of semitransparent material (e.g. viscoelastic) can be transparent enough for visual indicators such as displays and LEDs to be seen and light sensors to be able to measure light from the exterior of the case, but may otherwise mask the appearance of the components behind the thin sections. Thus, the case may present an unbroken surface in the area over the display, but the display may still be visible through the unbroken surface when displaying content. When the display is off, then the case may present a largely featureless surface over the display.
In the pictured implementation, the opening 660 may also serve as a window through which a display 618 of the biometric monitoring device 602 may be observed, as well as a window through which a button 616 of the biometric monitoring device 602 may be accessed.
The clip case 644 may also have a retention clip 658 that is configured to press against a side of the clip case 644 opposite the opening 660. The clip case 644 may be worn in any location where the clip can grasp a portion of what the user is wearing, where clothing or other material may be slid in between the retention clip 658 and the remainder of the clip case 644. These locations may include, but are not limited to, clipping the case to the user's pocket, belt, belt loop, waistband, shirt sleeve, shirt collar, shoe, shoelaces, hat, bra, tie, sock, underwear, coin pocket, or other articles of clothing, as well as to accessories such as a purse, backpack, belt pack, fanny pack, goggles, swim cap, glasses, sunglasses, necklace, pendant, pin, hair accessory, or earring. The retention clip 658 may be made out of a material such as polyurethane molded in such a form so as to accept a piece of spring steel that increases the spring force exerted by the retention clip 658 on the remainder of the clip case 644 such that the friction exerted on any material inserted between the retention clip 658 and the clip case 644 is higher than may be attained were the spring steel to be omitted. This may promote retention of the clip case 644 on the wearer's person. In other implementations, the retention clip may include a bare metal retention clip 658 (without being embedded within a polyurethane or other material), or may include a material other than polyurethane that surrounds a metal retention clip. In some implementations, the retention clip may not include any spring steel (or other metal) and may be made from plastic, e.g., molded polyurethane. In some implementations, the clip case 644 may also include one or more protrusions 656 or nubs on the side of the clip case 644 that faces the retention clip 658. The protrusions 656 may act to provide the retention clip 658 and clip case 644 with additional grip when attached to a wearer's clothing.

The wristband case 950 may be sized such that the wristband case 950 may be wrapped around a wearer's forearm such that a hook region 964 of the wristband case 950 may overlap with a loop region 962 on the opposite end of the wristband case 950. The hook region 964 and the loop region 962 may feature hooks and loops, respectively, of a hook-and-loop fastener system. Of course, other techniques for closing the wristband case 950 about a person's forearm may also be used, e.g., magnetic clasps, buttons, ties, elastic loops or ties, etc. In some implementations, the wristband case 950 may be a continuous loop of material that may stretch so as to be able to be pulled over a wearer's hand and worn on the wearer's forearm.
The depicted variant is similar to a wristband sold with the Fitbit One™, which measures approximately 9.5″ in length when laid flat, 2.5″ in width, and approximately 0.06″ in thickness. The loop region of this wristband measures approximately 4″ in length, and the hook region measures approximately 0.625″ in length.
As can be further seen in
The area surrounding the opening 960 may be impregnated with an elastomeric material 968 that may prevent fraying of the fabric through which the opening 960 passes and that may also serve to locally reinforce the fabric to prevent the opening 960 from opening too much. Stress relief holes 966 may be provided at either end of the slit that forms the opening 960 to mitigate the effects of flexure of the opening 960 due to repeated insertions and removal of a biometric monitoring device 902 (as shown in
While the opening 950 may be stretched to some degree, excessive stretching, e.g., sufficient to expand the opening 950 to a degree allowing the biometric monitoring device 902 to be inserted through the opening.
Alternatively, the device may be placed in the case by orienting it in a way which its dimensions are smaller or comparable to the opening. Once in the case, the device may be reoriented so that its dimensions along the opening are larger than the opening.
In the Fitbit One™ wristband case, the opening is approximately 1.25″ in length (as compared with the approximately 1.9″ length of the Fitbit One™) and the display window is approximately 2″ by 1.25″ in size.
It is to be understood that other implementations of a wristband case such as that shown in
One feature shared by such alternative implementations of a textile-based wristband case, however, is that the opening may be provided by a slit in a textile layer that is oriented such that the slit is aligned with the forearm on which the wristband case is to be worn. The present inventors have realized that this is advantageous over alternative orientations, e.g., perpendicular to the forearm, since such a location makes it more difficult for a biometric monitoring device that is inserted into the pocket to accidentally work its way out of the pocket and through the opening.
Cases similar to the textile-based case of
The design of the wristband cases may allow the user to change the closed circumference of the wristband cases by using an indexed clasp mechanism (similar to a watch buckle) or a hook-and-loop mechanism. Such wristband cases may use techniques similar to those already discussed herein to retain the biometric monitoring device in the wristband case, e.g., a stretchable undersized opening for insertion and removal of the biometric monitoring device. Similarly, the wristband case may use this opening, other openings, or case transparency to allow the user to see any displays or indicators of the biometric monitoring device.
Other cases, referred to herein as “band cases,” similar to the wristband cases discussed herein may be designed so that they may be worn in one or multiple locations including, but not limited to, the wrist, forearm, bicep, chest, stomach, waist, ankle, calf, quadriceps, neck, forehead, and finger. A wristband case may, for example, be worn on a person's forearm, but may also, depending on the size of the person's ankle, be worn on their lower leg. There may be multiple band cases that are specific to one or a set of these locations, allowing the user to choose which one is most appropriate for an anticipated activity. In some other implementations, band cases may have a main body that receives the biometric monitoring device and may have multiple interchangeable bands that have different characteristics including but not limited to color, width, length, material, and clasp type. In some implementations, the band clasp (an example of which is the peg component discussed in this disclosure) may be removable, allowing the user to use the same clasp with multiple bands. For example, the user may have one clasp that may be used with multiple bands of varying colors.
In some implementations, the wearer would have the ability to use a band case reminiscent of that of a watch including metal clasp mechanism as seen in
In some implementations, band cases may use an elastic band that does not require a closure mechanism. For example, a band case may have a metal band forming a C-shape that is elastic enough for the wearer to flex the opening of the metal band such that they may place the band case over their forearm. Once released by the wearer, the metal band may return to its un-flexed state, the elasticity of the metal band may provide a force around the wrist that prevents the band from falling off (without the use of a clasp).

The wristband case 1150 shown has a translucent window portion that is co-molded with the rest of the wristband case 1150 that serves as a display window 1172. The translucent window portion may completely encircle the wristband case 1102, as shown in the pictured variant, or may be located only in an area directly overlaying a display of the biometric monitoring device 1102. In the pictured implementation, the translucent window portion is made from a smoked or tinted plastic so that a wearer of the biometric monitoring device 1102/wristband case 1150 may be effectively unable to see the display of the biometric monitoring device 1150 through the display window 1172 unless the display is actually displaying content, e.g., illuminating pixels on a display or discrete LEDs.
The pegs may be molded plastic or metal in construction, and may generally be made from a much harder and/or stiffer material than the wristband case is (or at least the band portions of the wristband case). The pegs may be engaged with the peg holes by elastically stretching the hole openings to conform with the wider head of the protrusions. Once the peg or pegs are pushed through the band holes, the peg holes may contract again around the thinner portion of the peg geometry, thus holding the two band portions of the wristband case together at the desired circumference.
In another implementation, the pegs may be made out of a flexible material that can conform to harder and/or stiffer material in the wristband case. Alternatively, the pegs and the wristband case may both be flexible and may conform to each other to allow the head portion of the peg to be inserted through the peg hole.
The pegs 1186 may have bases that are embedded within the band portion of the wristband case 1150, or may, as in the depicted example, protrude from a base portion that is separate from the band portion (but that may be inserted into holes similar to the peg holes 1190 but are located on the band portion having the pegs 1186).
In addition to the head portion 1192, the peg 1186 may have a peg rib 1188 that is located between the head portion 1192 and the peg component 1184 base. The peg rib 1188 may act to secure the peg 1186 in a hole similar to the peg holes 1190 but located on the band portion opposing the band portion having the peg holes 1190. The peg ribs 1188 may be flared, e.g., have a 90° shoulder on the side facing the peg component 1184 base, and a 45° slope on the side facing the head portion 1192. This may facilitate retention of the peg component 1184 in the band portion when the wristband case 1102 is unclasped.

Since a person's arm and forearm are organic structures with widely-varying appearances from person to person, it may be useful to utilize a common reference framework when discussing such a limb or when discussing items that may be worn on such a limb. For example, despite the wide variation in shape and size of forearms in the general population, every forearm will have a forearm axis 1257 that is substantially aligned with the longest direction of the forearm. Another way of thinking of the forearm axis 1257 is as the axis that passes through the nominal centers of rotation of the wrist joint and the elbow joint. In addition to a forearm axis, it may be useful to refer to an elbow axis 1259 and a wrist axis 1253. The elbow axis 1259 may generally define the pivot axis of the forearm about the elbow joint during flexion and extension of the forearm, and the wrist axis 12 53 may generally define the pivot axis of the hand about the wrist joint during flexion and extension of the hand. An arm axis 1261 may be generally aligned with the long dimension of the arm and may pass through the center of rotation of the elbow joint and the center of rotation of the shoulder joint (not pictured). A hand axis 1255 may pass through the center of the wrist joint and generally in a direction aligned with the middle finger of the hand when at full extension.
As can be seen, the wristband case 1250 shown may encircle the forearm near the wrist and may generally define a wristband plane 1251 that is substantially perpendicular to the forearm axis 1257.
When the biometric monitoring device 1202 is worn in a wristband case such as wristband case 1250, the opening 1260 that is located in the “rear” of the wristband case may be blocked by the wearer's forearm, thus preventing the biometric monitoring device 1202 from being able to slip out of the wristband case 1250. In other implementations, however, the wristband case may be configured such that the opening is located in the “front” of the wristband case, e.g., facing away from the wearer's forearm.
It is to be understood that variations on the wristband cases discussed herein are also considered to be within the scope of this disclosure, e.g., band cases that are sized to be worn on other limb locations on a person. For example, a band case may be sized so as to be worn on a person's leg near the ankle joint, or on a person's arm, i.e., between the shoulder joint and the elbow joint. In some implementations, a band case may be sized so as to be worn by animals, e.g., pets such as cats and dogs. Such band cases may be worn by the pets as collars, e.g., around the pet's neck. In such implementations, the band case may generally define a band plane (similar to the wristband plane 1251) that is substantially perpendicular to the longitudinal axis of the limb or the spinal axis of the neck (depending on the location where the band case is intended to be worn). Generally speaking, a band case that is configured to be worn on an organism may refer to a band case that is configured to be worn on either a human or an animal.
In the implementation pictured in
The two-piece nature of the wristband case 1350 may be more fully understood with reference to
In general, it may be desirable that the band portions 1499 of a wristband case remain flexible enough to conform to the wearer's body in order to be as comfortable as possible. One way of achieving such flexibility and comfort is to use a sufficiently soft elastomeric material to construct all or part of the band portions 1499 of a wristband case. One problem that arises, however, is that as the material hardness is decreased, e.g., as measured by a durometer, there is a corresponding decrease in the holding force that the band portions 1499 may exert on the pegs of a peg component that are inserted into peg holes in one of the band portions 1499, i.e., it is easier to pull the pegs back through softer material and out of the peg holes.
One technique for addressing such possible issues is to include a second component (herein referred to as the “spine”) made from a harder material, e.g., a harder elastomer, than the rest of the band portion 1499. The spine may be either separately molded and then insert-molded inside the strap portion or molded sequentially in a double-injection type injection molding machine. The geometry of the spine may be such that the portions of the spine that may engaged with the pegs of the opposing band portion 1499 may be sized to be larger than the cross-sectional area of the peg stem and the peg head portion. Such geometry may result in the peg primarily contacting the harder spine material rather than the softer material of the band portion 1499. For example, if the pegs have a cross-section with a nominal stadium (or discorectangular) shape, i.e., a rectangle capped on two opposing sides by semicircles, the spine may, in each region around a peg hole, have a similar shape that allows the peg head portion to be inserted through the peg hole (and spine) and then rest on the spine material. Each region of the spine that surrounds a peg hole may be joined to adjacent similar regions by a smaller-width (as measured cross-wise to the band portion 1499) region of spine material so as to not greatly reduce the flexibility of the band portion 1499 while still providing for enhanced peg grip by the peg holes.
In other implementations, a band portion 1499 may contain two or more parallel spine components made from a harder elastomer than the rest of the band portion 1499. Each of these spine components may engage one or more pegs, for example, two parallel pegs. By varying the number of pegs, the force required to insert or remove the pegs can be varied by the designer.
In some implementations, harder and/or stiffer material may be incorporated into regions of the band portions 1499 other than where pegs holes are located in order to improve usability or cosmetic appearance. For example, the region of the band portion 1499 through which a peg component may be inserted (the band portion 1499 opposite the band portion 1499 with the peg holes) may be surrounded by harder, stiffer material to facilitate the insertion of the pegs into peg holes without needing to press directly on the peg component.
This construction allows the designer to tune the material characteristics of the band portion 1499 and the mechanics of peg/peg hole insertion separately without unduly compromising the cosmetic appearance and/or comfort of the strap assembly.
In
In the various implementations described herein, the case may have a feature which identifies itself to the biometric monitoring device or a secondary device, e.g., a smartphone paired with the biometric monitoring device. For example a wristband case may have an NFC tag which can be read by an NFC communications interface of the biometric monitoring device (or smartphone paired with such a device). Other identifying features may include an RFID tag, other wireless communications technologies (passive or active), a magnet, or circuitry electrically connected to the device. The biometric monitoring device may change its functionality depending on the case identifier. For example, a wristband case identifier may cause data obtained by the biometric monitoring device to be interpreted with respect to a framework based on the assumption that the biometric monitoring device is located on a person's forearm near their wrist. This change in functionality could include a change in algorithm of counting steps if the device were to include a pedometer and/or the display of the time. In another implementation, the wristband may contain a magnet on one side of the band whose position can be measured by a magnetometer in the device and used correct the orientation of the display.
Other implementations regarding the use of short range wireless communication are described in U.S. patent application Ser. No. 13/785,904, titled “Near Field Communication System, and Method of Operating Same” filed Mar. 5, 2013 which is entirely incorporated herein by reference.
Generally speaking, the above-discussed cases may have channels, vents, and/or windows in them to allow a pressure transducer or altimeter in or on the device housing to be exposed to the ambient pressure, e.g., water or air pressure, in the vicinity of the biometric monitoring device. Examples of such channels, vents, or windows may be found in ventilation holes 652 of
