DETAILED DESCRIPTION

[Θ14] In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative examples described in the detailed description, drawings, and claims are not meant to be limiting. Other examples may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented herein, it will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the Figures, can be arranged, substituted, combined, separated, and designed in a wide variety of different configurations, all of which are implicitly contemplated herein.

[015] Examples of mobility devices described herein may provide a wide array of functionalities. Generally, numerous embodiments of a multi-functional smart and connected mobility aid device are described herein where the device may have any combination of features as described herein. Such devices may help users to be more independent. Smart mobility aid devices descried herein may have sensors to collect, monitor, analyze and/or represent data including but not limited to activity tracking, biometrics and safety and emergency features. The activity tracking may include tracking a number of steps, distance (e.g. miles), and/or activity speed, user applied pressure on a smart cane or other mobility device, activity types and/or analysis The biometrics data may include but is not limited to blood work, blood pressure, blood sugar, heart rate, oxygen level/rate, ECG, EMG, muscle strain, humidity, UV, and/or body temperature. In some embodiments, the safety and emergency features may include an emergency button, fall detection and warning, and/or user activity pattern collection and analysis of activity pattern changes. In some embodiments, sensors may^¬ be placed on strap connected to a mobility device to collect and monitor data automatically. Also, there are smart mobility aid embodiments that include a medication management system that reminds and monitors a user medication schedule. The mobility device data may be represented in the form of visuals, sound/voice, and/or vibrations. The mobility device may be connected to other devices and/or the Internet using for example, Bluetooth, Wi-Fi, and or/and SIM card. In addition, mobility devices may analyze how a user walks using the device and advise a user to improve his walking pattern, for example.

[016] Any of a variety of mobility devices may be used to implement mobility devices described herein, including but not limited to, a wheelchair, a cane, a walker, a cmtch, a scooter, a shoe, or combinations thereof.

[017] In some embodiments, a strap may be provided that may be coupled to the mobility device. Multiple touch sensors may be arranged on the strap (e.g. on the interior of the strap), and the multiple touch sensors may be fuiiher coupled to a processor. The processor may be integrated with the mobility device (e.g. attached to and/or positioned within some portion of the mobility device, e.g. in the handle, seat, and'Or other member of the mobility device). The processor may be coupled to (e.g. in electronic communication with) multiple touch sensors and a position sensor. The position sensor may be implemented, for example, using one or more gyroscopes, accelerometers, GPS devices, or combinations thereof. The processor may receive signals from the position sensor indicative of a fall of the mobility device. An alarm may be provided in response to the position signals indicative of the fall . In some examples, it may, however, be advantageous to improve fall detection by discerning whether or not a user has fallen together with the mobility device. For example, if a position sensor of the mobility device indicates a fall, it may be in some examples that the mobility device has simply fallen and then user may or may not have actually fallen. Accordingly, in some examples a fall alarm may only be provide when an indication is present that the user is still attached to the mobility device. [018] In some examples, mobility devices described herein may include a lock mechanism for interchanging tips on the mobility device - e.g. tips on a cane, for example. A variety of tips may be used for different situations - e.g. smgle-tip, dual- tip, tri-tip, quad-tip. Locking mechanisms described herein may have one or more guide grooves and one or more convex guide portions. Tips may have one or more buttons that are coupled to one or more locking hooks, and an extending shaft having one or more mating guide grooves.

[019] In some examples, wall mounts for mobility devices may be provided. The wall mount may include a horizontal member coupled to a vertical member. The horizontal member may have a shaped end configured to receive a portion of the mobility device to stabilize the mobility device in when the device is not in use. A holder having a convex portion coupled to the horizontal member may receive a charging cable and the shaped end of the horizontal member may provide stability to the mobility' device while the mobility device is being charged.

[020] FIG. 1 illustrates a system 100 including a processor 102 coupled to an alarm

112 and a strap 1 10 according to the present disclosure. The processor 102 may receive signals from a position sensor 104, touch sensor(s) 106, and an accelerometer 108. The processor 102, alarm 112, position sensor 104, touch sensor(s) 106, and accelerometer 108 may be attached to, positioned on, and/or integrated in a mobility device (e.g. a cane, walker, wheelchair, crutch, shoes, etc). The position sensor 104 may sense a position of the mobility device. The accelerometer 108, for example, may be used to implement, wholly or partially, the position sensor 104. The accelerometer 108 may measure a speed or an acceleration of the mobility device, for example, when it is falling. A strap 110 may be used to determine a user's proximity to the mobility device. For example, the strap 110 may include one or more touch or other sensors which may determine a presence and/or proximity of a user. The strap 1 10 may sends signals to the processor 102 using the touch sensors 106. The processor 102 may send a signal to an alarm 112 when a fall is detected and the user is still attached to the mobility device (e.g. when the touch sensors indicate the user is touching and/or proximate the strap 1 10). The processor 102, the position sensor 104, and the accelerometer 108 may be integrated in a handle of the mobility device in some examples. While not shown in Figure 1, the system 100 may include computer readable media (e.g. memory, storage) encoded with executable instructions. The computer readable media may be in electronic communication with the processor 102 and, when executed by the processor 102, the executable instructions may cause the system 100 and/or the processor 102 to perform functions described herein. Accordingly, the mobility device may in some examples include software and may be programmed to perform functionality described herein. While a processor 102 is discussed, it is to be understood that any number of processing units may be used, and custom circuitry may be used in lieu of or in addition to processor 102 in some examples.

[021] The strap 110 may be physically attached to the mobility device in a detachable or un-detachable manner in various examples. The strap 1 10 may in some examples detach from the mobility device when a sufficient force is applied (e.g. when the mobility device falls away from the user, the user moves away from the mobility device, or combinations thereof). The touch sensors 106 may be arranged on the strap 1 10 (e.g. on an interior of the strap 1 10). The touch sensors 106 may periodically send touch signals to the 102. The processor 102 may determine that the user is not touching the strap when the user is detached from the mobility device if touch sensors 106 send signals indicative of the user not being attached to the mobility device (e.g. an absence of signals from the touch sensors 106 in some examples).

[022] The alarm 112 may communicate with another system (not shown). The another system may include a system that is remotely located from the mobility device. For example, the alarm 1 12 may initiate communication with a care provider, emergency contact, the mobility device user, or some other entity. The alarm 1 12 may initiate communication using, for example, messaging, Internet communication, email, phone, text, auditory, visual, and/or other signals.

[023] In some examples, the user of the mobility device may carry a wireless connector (not shown), for example, a pendant or a receiver unit. Wireless signals from the wireless connector may be provided to the processor 102, e.g. through a receiver which may be included in system 100 in some examples. The receiver may be attached to and/or integrated with the mobility device. The wireless signals from the wireless connector may provide proximity information regarding a user, in some examples, proximity information may be inferred via wireless signals, for example, Wi-Fi and Bluetooth, between the strap 1 10 and the mobility device. The strap 1 10 and the wireless connector may assess motion and orientation of the user and/or the mobility device and communicate this information to the processor 102. The system may include a battery or other power source (not shown) to store energy and power some or all of the components described. The batter}^' or other power source may be attached to and/or integrated with the mobility device. Power harvesting circuitry may in some examples be used to implement all or portions of the power source - for example solar, wind, thermal, vibrational, or other power harvesting from an environment may be used.

[024] The strap 102 with touch sensors may be used to provide a variety of functionality. For example, signals from the touch sensors may be used to determine when to turn on and/or off various functionality of the mobility device (e.g. a display screen, voice command functionality, etc.), because the touch sensors may indicate that a user is using the device and/or is proximate the device.

[025] FIG. 2 is a flowchart illustrating an example method in which an alarm is provided responsive to received signals according to the present disclosure. In block 202, one or more position signals indicative of a fall is received from the position sensor 104. For example, accelerometer, gyroscope, and/or GPS signal may be received from the position sensor 104 which may indicate a fall. The processor 102 may analyze the signals and identify the fall (e.g. utilizing fall detection aigorithm(s) programmed in the mobility device and/or in a system in communication with the mobility device). In block 204 the processor may evaluate whether the user is still touching the strap after the fall, for example, by analyzing signals received (e.g. the presence and/or absence of signals) from touch sensors on the strap. If it is determined that the user is still touching the strap after the fall in block 204, then the alarm is provided in block 206. The aiarm may be sent to, for example, an emergency operator, a registered family member, or a registered care taker. If it is determined that the user is not touching the strap after the fail in block 204, then the aiarm will not be provided as illustrated in block 208.

[026] FIG. 3 illustrates an embodiment of a lock mechanism 300 of a mobility device according to the present disclosure. The lock mechanism 300 may include an extending shaft 302, guide grooves 304 and 306, locking hooks 308 and 310, buttons 312 and 314, and a base 316. The base 316 may include an upper base 318 and a lower base 320. The extending shaft 302 houses the guide grooves 304 and 306. The mobility device houses mating guide grooves (not shown) configured to mate with the guide grooves 304 and 306. The extending shaft 302 is attached to the base 316. The base 316 houses buttons 312 and 314. The buttons 312 and 314 may activate the locking hooks 308 and 310. The buttons 312 and 314 are disposed on the exterior of the base 316. The locking hooks 308 and 310 may hook onto the matching receiving portion on the mobility device (e.g. an interior of a cane shaft), such that when the extending shaft 302 inserts into the mobility⁷ device along the mating groove, the mobility device is locked onto the base 316.

[027] The base 316 may turn clockwise or counter-clockwise. The base 316 may attach to the mobility device, for example, a cane. The lock mechanism 300 may generally attach to any of a variety of mobility devices and/or also attach to devices or products that need easy lock-unlock mechanism, for example, a camera tripod. The mechanisms may be used to interchange base portions of a walker, for example (e.g. to change to/from a tennis/baseball base portion). The lock mechanism 300 may attach to and detach from the mobility device. The base 31 may house two or more locking hooks and buttons to provide additional safety features.

[028] In this manner, a bottom end of example mobility device bodies may be designed in a way that allows an easy replacement process of the mobility device base. The base tip may be replaced based on user preference, the condition of the user and/or the environment that it will be used on for example. Any of a variety of tips may be used, including basic base, tripod base to make the mobility device self-standing, flexible, ice tip, etc.

[029] FIG. 4a illustrates one embodiment of a wail mount 400 according to the present disclosure which may be used to support and/or charge a mobility device. The wall mount 400 may include a vertical member 402, a horizontal member 404, a convex portion 406, and a holder 410. The vertical member 402 may be coupled to the horizontal member 404. The horizontal member 404 may have a shaped end portion 408, and the shaped end portion 408 may receive a portion of the mobility device to stabilize the mobility device when the device is not in use. The holder 410 may be coupled to the horizontal member 404 and may further receive a charging cable (not shown). The shaped end portion 408 stabilizes the mobility device such that a charging port of the mobility device may be aligned with the convex portion 406 to connect the charging cable.

[030] The vertical member 402 may attach to a surface, such as using one or more nails, screws, adhesives, and/or Velcro®. The surface may, for example, be a wall. The vertical member 402 may have a dimple (not shown) to further provide support for the mobility device (e.g. into which a portion of a cane handle may rest).

[031] FIG. 4b illustrates a perspective view of the wall mount 400 with the shaped end portion 408 receiving a mobility device, for example a cane, according to the present disclosure. The shaped end portion 408 is receiving a narrow portion of the cane and an indent (not shown) on the vertical member 402 may further provide support for the mobility device. In some embodiment, the holder 410 is coupled to the charging cable such that the convex portion 406 and the charging cable are aligned with the charging port of the mobilit ' device.

[Θ32] FIG. 5 illustrates one embodiment of a strap 500 according to the present disclosure. The strap 500 may include a plurality of sensors 502 and an attachment portion 504. The attachment portion 504 may attach to the mobility device at one end (e.g. at a handle of a cane or walker). The plurality of sensors 502 may connect to a user's body, for example, wrist, ankle, neck, and/or hand and collect user data. The strap 500 may be used to determine whether the strap 500 is connected to the user or not connected to the user (or proximate or not proximate the user). The strap 500 may- detach itself from the mobility device when a sufficient force is applied. When a processor of the mobility device no longer receives signals indicative of user touch or a proximate user, the processor may determine that the user is no longer physically tethered to the mobility device.

[033] The strap 500 may attach to the mobility device using non-physical connections, such as a wireless connector (not shown). Proximity of the user to the mobility device may be communicated from the strap 500 to the mobility device through wireless signals in some examples (e.g. using a transmitter on the strap and a receiver on the mobility device). The strap 500 may include a battery and/or other power source to store energy (not shown). When detachment of the strap 500 from the mobility device, or separation between the strap 500 and a wireless unit is detected, the strap 500 may activate a voice command feature or initiate a 2-way voice communication. The strap 500 may be used to detect user motions and, for example, confirm an increased likelihood that a user fell.

[Θ34] FIG. 6 illustrates one embodiment of a mobility device, for example, a cane 600 according to the present disclosure.

For example, there may be an open API for developers to include additional features for mobility devices described herein.

[063] In some examples, mobility devices described herein may be responsive to voice commands. Mobility devices may house a receiver that is capable of receiving and responding to voice commands. In some examples, voice command functionality may be kept dormant, by default, for battery savings. However, it may be activated in a variety of situations. By employing the built-in sensors and algorithms, the receiver may be able to detect when it or the user falls down. Once a fall is triggered, the voice commands feature may be activated.

[064] In some examples, the voice command features may allow mobility devices described herein to detect certain pre-programmed and non-preprogrammed instructions. These may include both emergency instructions, such as, "Help", "I'm hurt", "I can't get up", "Call my daughter", "Get 9 1 ", "I need a doctor", etc, as well as non-emergency instructions, "I'm okay", "Turn on the lights", etc.

[065] In the event of an emergency situation, the receiver may be able to automatically initiate 2-way voice communication with a pre-designated contact, e.g., family member, neighbor, caregiver, help-line, emergency services. The receiver may also be able to send location information, to provide the contact with their geographical location.

[Θ66] In some examples, mobility devices described herein may detect when a fall (device and/or user) occurs and may analyze the sequence of events leading up to a fall. Mobility devices described herein may detect imbalances in the user and even when a fall sequence is triggered. Additionally, mobility devices may determine when falls may have been avoided; that is, when a likely fall is triggered but does not occur. This information is collected and included in the user's fail risk assessment. An increasing number of falls avoided may suggest that the individual is becoming increasingly unstable and might need to modify their diet, medication, physical activity, or mobility- aid devices.

[067] To detect when falls are triggered and occur or triggered and avoided, mobility devices described herein may utilize a combination of sensors, including load/force, grip, inertia, motion, position, slip, and/or orientation sensors.

[068] in some examples, mobility devices described herein include an indicator light system. One or more indicator lights may provide qualitative and/or quantitative feedback about the user's physical activity and/or goals. In some examples, the lighting system may change colors based on the progression towards the user's personal or preprogrammed goals. The goals might be, for example, overall activity duration or distance traveled.

[069] The indicator light system may include a single LED, or other type of light, or a series of lights. The system may emit a single color or be capable of multiple colors. As the user tracks towards their goals, the system might provide feedback through lighting intensity, color, or frequency.

[070] This system might be used concurrently or independently from other quantitative feedback system(s). The lighting system, might adjust periodically to compensate for user's activity and/or their goals.

[071] In some examples, mobility devices may have a modular design where parts can be interchanged for similar or different parts. For example, in the case of a cane, the tips might be interchangeable (e.g., mono-tip, tri-tip, quad-tip). The interchangeable parts could communicate with other components described herein, so that the device is aware of the components connected. For example, a tip may store an identification of a type and/or function of the tip in, for example, a memory of the tip. When connected to the mobility device, the tip may provide the identification to one or more processors) of the mobility device, and'or the mobility device may queiy the memory of the tip to determine the identification.

[072] The smart box is able to make recommendations to the user about what parts to use. Factors influencing this include extrinsic factors such as environmental conditions (e.g., rain, snow, ice, etc.) as well as intrinsic factors such as user's gait and balance. This recommendation may help the user maintain the optimal balance between security, stability, and mobility.

[073] Example mobility devices described herein may include an image sensor and/or camera which may allow the mobility devices to observe the environment nearby the user. The imaging components may be able to detect obstacles and provide warnings to the user. Warnings may be provided of potential hazards - e.g. steps, changes in elevation, cracks or holes, rug edges, door slips, common areas that users might encounter that increase their risk of falling, etc.

[074] The imaging technology might operate in the visible light range (e.g. traditional camera), or infrared spectrum (e.g. thermographic camera). [075] Example proximity detectors might also use sonar, infrared, and/or another type of distance system. Proximity detectors may be capable of detecting distance and also other properties, such as temperature and/or density.

[076] Example mobility devices described herein may also include an augmented/enhanced reality projection system. The mobility devices may utilize lighting to highlight potential hazards on the augmented/enhanced reality system directly. The augmented/enhanced reality system may also provide audio and tactile feedback to alert the user of one or more hazards.

[077] Examples of cameras described herein may be accessed by third parties to see the environment around the user and have the ability to monitor or/and to give the user instructions, explanations, and/or turn by turn navigation (e.g. by voice or/and vibration) when desired - e.g. in case the device user is blind.

[078] In some examples, mobility devices described herein may be battery operated and thus may have sensors and systems that may be inactive at times to save power. However, when charging, these systems may be fully activated. This may allow the mobility device to be responsive to voice commands from the user, as well as detect general safety alarms including, fire, carbon monoxide, burglary, etc. Example motion/proximity sensors may also be active when charging and could, for example, turn on the lights of the mobility device to help the user identify its location.

[079] Examples of mobility' devices described herein may contain an electronics board hosting the various sensors, processors, batteries, and/or other electronic devices. This electronic board may be strong enough to support the user's weight in some examples, or a portion of the user's weight. The board may be connected to the shell, which acts as a casing for cosmetic purposes and also for protection. The board might also be arranged in an orientation that allows it to maximize its strength based on directionality and alignment of the fibers in the board.

[080] Example mobility devices described herein may include one or more smart buttons able to read biometrics directly from the user (e.g. from the user's fingers). Biometrics/vitals may be read non-mvasively through skin contact of the user (e.g. finger). Biometrics which may be gathered include but are not limited to, heart rate, blood pressure, body temperature, respiratory rate, glucose, and/or perspiration. This information may be displayed directly to the user and/or uploaded to the cloud or other remote system for access by the user and/or third parties (e.g. caregivers). The smart button may be used in any device including but not limited to, mobility device, smart phone, watch, and/or laptop.

[081] In some examples, mobility devices described herein may be able to confirm the user through various identity detection methods. Mobility devices may include user- recognition technology, such as a fingerprint reader, facial recognition, voice recognition, etc. These systems may distinguish fingerprints and/or vocal patterns. The fingerprint recognition system and/or voice recognition system may be embedded in the smart button and-'or voice command system, respectively in some examples.

[082] In some examples, mobility devices described herein may include a smart clock that could be viewed in the mobility device or any electronic device. The clock may update itself based on the location e.g. when traveling of the user or at any specific time of the year e.g. time saving in the US. The clock may be powered from the power source used to power the electronic device, an independent battery including but not limited to RTC butteries, solar ceil or/and power generated by physical movement, for example, walking with the cane, walker or a shoe. The clock could be presented in different formats, in numbers, dots, shapes or voice. In some examples, the clock may be positioned such that the user could see the time while holding the mobility device or it could be hidden while the device is held.

[083] Example mobility devices described herein may differentiate between pressing a button after a fall or not. Example mobility⁷ devices may determine a fall using one or more metrics including but not limited to device orientation, device shock, device acceleration, device rotation, etc. One of the methods to identify that is by first identifying a device drop (fall) or not. If the device detects that it was dropped, then the user press a button while being in the same position or a slightly different one, the help request or the notification will be treated as a fail. That could result on initiating a phone call, calling 91 1, testing, sending data, email, over-data call massage or notification, turning on an alarm, etc. If the user presses the button and the device has not been dropped (e.g. no fail has been detected), the button could initiate, for example, a non-emergency phone call to a family member, sending a non-emergency text, email, or cause a control signal to be transmitted to another device (e.g. turn lights on/of turn television on/off). In this manner, the button may cause one action after a fall event (e.g. cause an emergency alert) and another action when no fail event is detected (e.g., non-emergency communication or control of another device). This method could be implemented in any mobility device - e.g. a cane, a walker, a watch, a shoe, a wheelchair or any other devices. This method could be implemented using any kind of triggers including but not limited to pressing a physical button, pulling a cord, waving, voice, saying words, e.g. help , changing in ambient light, noise or temperature or any other input.

In some examples, mobility devices described herein may be adjustable. Mobility devices may be adjusted manually using a height adjustment mechanism or automated using motors. Mobility devices, e.g. canes, may adjust to the height of the user based on user height automatically by measuring the height of the user and changing itself to the optimal height. The mobility device may measure user metrics such as height, using one or more sensors such as radar, lesser, etc., and changing the height to fit the user. The adjustability could be done mechanically, e.g. by a button release mechanism. The one or more buttons could be located on a cane handle, on the shaft, or on the tip. The user can change the height of the cane in some examples by pressing one or more buttons that releases a pressure element one of shafts. The buttons could trigger a small motor to pressure or release the pressure to accomplish locking or unlocking the height adjustment mechanism.

In some examples, mobility devices described herein may locate themselves indoors accurately, such as, by communicating to one or more beacons (e.g. .transceivers) placed in one or more predefined locations using different wireless and/or radio technology such as Bluetooth®, ZigBee®, Wi-Fi, etc. In this manner, the mobility device may identify if the user in a specific room, or a specific table, or even a specific chair. This may advantageously be used inside malls, airports, hospitals, houses, or senior communities.
