The present disclosure relates in general to the field of computer systems, and more specifically, to a recharger for wearable devices and other smart textile-based devices.
Computing devices such as personal computers, laptop computers, tablet computers, cellular phones, and countless types of Internet-capable devices are increasingly prevalent in numerous aspects of modern life. Over time, the manner in which these devices are providing information to users is becoming more intelligent, more efficient, more intuitive, and/or less obtrusive. The trend toward miniaturization of computing hardware, peripherals, as well as of sensors, detectors, and image and audio processors, among other technologies, has helped open up a field sometimes referred to as “wearable computing.” A variety of wearable computing devices are being developed allowing electronic components to be carried on human and animal users.
Like reference numbers and designations in the various drawings indicate like elements.
In one example, a clothes hanger device is provided that includes modules, which may wirelessly transfer power and/or data to/from electronics integrated in a garment. In some instances, a smart garment may be powered by rechargeable batteries and the clothes hanger may provide inductive, capacitive, or radiative charging of batteries included in garments equipped with electronics to enhance the garment. Indeed, “wireless” power or energy transfer, as used herein, may refer to inductive, capacitive, or radiative energy transfer. Further, the clothes hanger may include an antenna and communication module to enable the uni- or bi-directional transfer or receipt of data to/from the garment, for example to receive system data, data log, or reprogram the firmware in the garment. For instance, the garment (e.g., through sensors integrated on the garment) may collect and record data over a period of time (e.g., hours, days, months, etc.) and “dump” it on the hanger unit when recharging (for example, on a memory stick integrated with or connectable to the hanger). Further, data may be uploaded to or otherwise provided on the hanger, which the hanger can share with the garment (e.g., for use in upgrading or reprogramming logic of the garment (e.g., firmware update)) and data from the garment can be used for log transfer, or to transmit malfunction signals, among other possible examples
In one example, a charging clothes hanger (or simply “charging hanger” may include a power source, such as a battery or a connection to an external source (i.e. via a cable), from which power may be transferred to a charger of battery unit(s) in a garment. The charging hanger may additional include (e.g., contain) one or more electromagnetic radiators/receivers, resonators, or other electromagnetic component capable of transferring power and/or transmitting and/or receiving data to electronics in garments via coupling with one or more radiators/receivers or resonators provided on the garment (e.g., integrated into the fabric of the garment, or otherwise attached to the garment). It should be appreciated that, while the disclosure discusses “resonators”, this term, as used herein, refers both to elements which are resonant as well as those that are sub-resonant. Further, in implementations utilizing radiative or capacitive charging, other circuitry and elements may be provided to implement the corresponding power transmitter and receiver (e.g., other than resonators). For instance, for an implementation utilizing capacitive charging, an electrode charge plate may be provided within each of the charging hanger and the textile device to be charged using the hanger. Similarly, in implementations utilizing radiative charging, or power beaming, the charging hanger may be provided with an antenna, laser aperture, or other element to transfer energy from its power source to the receiver on the smart garment, or other textile device, among other examples.
In accordance with the foregoing, an example charging hanger may serve as a wireless charger for power sources powering electronics integrated into clothing, such as lighting, speakers, sensors (i.e. electrodes or optics for a heart rate monitoring device, stretchable fibers serving as piezoelectric sensing elements for applications such as a respiration sensor, etc.), or any other medical or consumer electronic device that is built into a piece of clothing. This charging/recharging of the battery-equipped garment may thus take place while the garment is being hung (e.g. in a closet) using the charging hanger. In some cases, the unit embedded in the hanger can be removed from the hanger, thus enabling a stand-alone charging system which may be suitable, for example, for travel. In some implementations, the charging hanger device may provide wireless charging in accordance with one or more defined charging standards. Such standards may include, as examples, the Wireless Power Consortium's Qi standard, standard provided or endorsed by the AirFuel Alliance, among other examples.
Turning to the particular example of
Additional circuitry may be provided within the body of or otherwise contained within the clothes-hanger-shaped device 100. For instance, in addition to the power transfer element 105, circuitry 110 may be provided to detect when other devices have been brought into contact with or sufficient proximity of the power transfer element 105 to be charged by the power transfer element 105. Additionally, charge monitoring circuitry 110, such as a microcontroller or battery charger integrated chip, may be provided in the hanger device 100 to detect the charging status of a battery or other energy store of the other device charged by the hanger device 100. For instance, the charge monitoring circuitry may identify when charging of the other device is being performed by the power transfer element, as well as, in some instances, detecting when the subject other device is fully charged. In some implementations, the device being charged by the hanger device may include a battery charge detection circuitry and may send a wireless signal to the hanger device, which may be received by an antenna of the hanger device to determine that charging has been completed, thereby causing the hanger device to cease charging (e.g., to conserve energy), among other example features.
In some implementations, a visual or audio indicator may be provided in or on the hanger device 100 to indicate the detected charging status to a user. In one implementation, one or more light emitting diodes (LEDs) may be provided in the hanger device to present various colors or patterns of light to indicate charging status of an electronic article of clothing hanging on the hanger device. For instance, the hanger device may be composed of hollow plastic, which is at least partially transparent to allow light emitted from LEDs within the hollow hanger body to illuminate the hanger body so as to indicate to a user that an electronic garment hanging on the hanger device is charging or charged, among other examples. Indeed, in some implementations, the hanger device 100 may be composed of a housing for the power transfer element 105, charge monitoring circuitry 110, a power supply (and associated circuitry) (e.g., 115), indicator devices (e.g., LEDs, speakers or chimes for audio indicators, etc.), among other components of the hanger device. The housing of the hanger device 105 may be formed from plastic or another material. Remaining portions of the hanger device 105 may be composed of the same or different material as used in the housing of the hanger device 105, among other example implementations.

Accordingly, in some implementations, such as illustrated in
In some implementations, to ensure optimal coupling between power transmitter and receiver elements, such as resonators (e.g., a transmitting coil and receiving coil or other power transmitter/receiver combination), additional components may be provided in example charging hangers and/or smart textile products to assist in aligning the transmitting resonator on the surface of or embedded within a charging hanger device with the receiving resonator in or on the fabric of a smart textile product (e.g., a smart garment). As one example, permanent magnets may be placed in the core or outside of one or both of the transmitting or receiving resonators, with a corresponding ferromagnetic material placed within or near the other device. For instance, in the example of
Further, some implementations may alternatively or additionally utilize other components, such as clips, snaps, zipper, buttons, female/male connectors, among other components to temporarily and mechanically connect or otherwise align resonators of an example wireless power transmitter element (e.g., 105) and a wireless power receiver element (e.g., 205), among other example features. In some implementations, the alignment mechanism (e.g., whether mechanical or magnetic) may additionally include a sensor to indicate how a garment is aligned with the power transfer elements of the hanger, such that when a particular connector or alignment mechanism of the hanger is engaged, the circuitry and/or logic of the hanger can determine that a corresponding power transfer element (and/or data transmitting or receiving element) is capable of being successfully engaged. In some cases, such sensors may additionally trigger visual or audio indicators (e.g., lights or sounds) to provide feedback to the user that the garment and hanging device are properly (or improperly) aligned, among other examples. For instance, in an implementation of a charging hanger device with multiple alternative power transfer elements provided in different locations of the hanger (e.g., as in the examples of
As noted above, a charging hanger may transmit power from a power source to electronics of a garment to charge a power source (e.g., a battery) powering the garment circuitry that provides various enhancements to the garment (e.g., sensors, user interfaces, visual or audio enhancements, etc.). In some implementations, the charging hanger may be provided with an internal power source, such as a battery. This may allow the charging hanger to operate in portable configurations (e.g., in luggage, in a hotel, etc.) and charge equipped smart garments outside of a home environment. In some instances, the battery (or other power supply) of the charging hanger may be rechargeable. In one implementation, the charging hanger device may be provided with additional features to facilitate recharging of the charging hanger's power source(s) directly at the charging hanger. For instance, turning to
In another example implementation, illustrated in
In one example, as shown in
In some cases, a wireless charging hanger may be a single device that contains all components previously mentioned, or it can serve as a modular device allowing the features containing the power source and resonator to be selectively removed from (and function independent from) the clothes hanger structure. A modular approach may allow wireless recharging components to be used without the garment being hung on the hanger (e.g., while the garment is being worn, when the garment is folded and stored (e.g., in a dresser), or when the garment is stowed in luggage, a workout bag, etc. Additionally, in one example of a modular charging hanger, recharging elements may incorporate a battery, such that the recharging elements may be removed from a hanger to allow the recharging element to be conveniently recharged (e.g., before being reattached to the hanger). In other instances, a recharging element may function (and be designed for implementation) independent from the hanger. For instance, a recharging component (e.g., equipped with magnets or clips to connect the recharging component to a garment) may allow wireless recharging of a garment's battery without the use of a hanger structure. This may be useful, for instance, in cases where a textile product is too larger otherwise shaped such that hanging the product on the hanger device is impractical or would not result in resonator alignment, among other example considerations and use cases.

As introduced in the discussion of
A fluidic wire may be reversibly deformable and mechanically tunable and may be formed by injecting a liquid metal, such as gallium or a gallium-based alloy, into one or more sheaths or other cavities within a material substrate or a base material (e.g., coupled to a bonding layer material). Any liquid metal that has a melting point below an ambient liquid metal wire manufacturing facility temperature or the temperature of the desired operating environment may be used such that heating of the liquid metal is not required for the liquid metal to be introduced during manufacturing or for the liquid metal to retain its deformable properties in application. An example temperature range from negative twenty degrees Celsius (−20° C.) to forty degrees Celsius (40° C.) may be used in association with certain of the metals described herein that are in a liquid state within this range, though it is understood that other temperature ranges may be appropriate for other implementations of liquid metal to be used to form a reversibly deformable and mechanically tunable fluidic wire. In one example, eutectic gallium indium (EGaln) has a melting point of fifteen and seven tenths degrees Celsius (15.7° C.) and given the supercooling property of gallium may maintain this liquid property at temperatures even lower than its melting point, allowing EGaln (and other gallium-based alloys) to be used as the liquid metal within an example fluidic wire. As such, a lower end of the ambient liquid metal wire manufacturing facility temperature range for such an implementation may be considered, for example, sixteen degrees Celsius (16° C.). Other metals and temperature ranges may be used for formation of liquid metal wires that may have higher or lower melting points, and as such, different ambient liquid metal wire manufacturing facility temperature ranges.
In some cases, a fluidic wire may be constructed by injecting the liquid metal into a wire housing or sheath, or other cavity. As an alternative to injecting a liquid metal into one or more cavities, the liquid metal may be drawn into a cavity by applying a vacuum or other pulling force to the liquid metal via the cavity. In either implementation, injecting or drawing the liquid metal into the cavity may be terminated in response to the cavity filling to capacity. Alternatively, filling the cavity may be terminated on demand by cessation of the filling process upon filling of the cavity to an extent sufficient to allow radiation of electromagnetic energy via the fluidic wire. Inlet and outlet filling hole locations may be provided for the respective operations, and the cavity may be sealed in response to filling the cavity.
The term “fluidic wire” and “liquid metal wire” may be used interchangeably to represent a wire with a liquid metal resonant element. The term “material” and “substrate” may be used interchangeably to represent a substance within which a fluidic wire may be formed. The term “cavity” may be used to represent a hollow channel, capillary, conduit, sheath, groove, furrow or other structure within a substrate within which liquid metal may be filled to form a fluidic wire. The terms “cavity,” “channel,” and “capillary” or other terms may be used interchangeably hereafter to identify a void or other structure, within one or more portions of material that define a shape of a fluidic wire within the material, that may be filled with liquid metal to form a fluidic wire. For certain implementations, a channel may be considered a “microfluidic channel.”
The material within which the cavity and fluidic wire are formed may include a flexible and/or stretchable material, for example, an elastomer such as silicone or other polymer-based materials. Other examples of flexible materials include polymer films, composite substrates, gels, thin metal supports, and other flexible materials. The material within which the cavity and fluidic wire are formed may also include rigid materials such as wood, dry wall, polymeric parts, polymer films, gels, and other rigid materials. It is understood that the present subject matter applies to any material that may form a cavity that may define a shape of a fluidic wire without interfering with spectral properties of the fluidic wire beyond interference acceptable within a given implementation, and all such materials are within the scope of the present subject matter.
A cavity may be formed into a substrate in a variety of manners. Because the wire is formed with a liquid metal, the mechanical properties of the wire may be defined by mechanical properties of the substrate. As such, for an elastomeric substrate, the resulting elastomeric fluidic wire may be deformed (e.g., stretched, bent, flexed, rolled, etc.) and released/reversed without loss of electrical continuity. As a consequence, the resulting wires may be more durable relative to conventional technologies and may be utilized in applications that would otherwise result in destruction of conventional wires. Strain may be induced in a material, for example, in response to temperature changes, pressure changes, mechanical load changes, geographical changes, or any other change that results in a force on the material that deforms, elongates, shrinks, or otherwise changes the material's dimensions. For example, the fluid metal may flow in response to strain (e.g., elongation) of the elastomeric substrate, resulting in a reconfiguration of the geometry of the fluidic wire and a resulting shift in the resonant frequency of the wire, while returning to its original geometry and frequency response upon removal of the applied strain. Based upon these properties, the fluidic wire is considered to have no or minimal hysteresis, as defined by the mechanical properties of the substrate in response to mechanical strain and release of mechanical strain.
Reference throughout this specification to “one implementation” or “an implementation” means that a particular feature, structure, or characteristic described in connection with the implementation is included in at least one implementation of the present Specification. Thus, the appearances of the phrases “in one implementation” or “in an implementation” in various places throughout this specification are not necessarily all referring to the same implementation. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more implementations.
The following examples pertain to embodiments in accordance with this Specification. In some implementations, an apparatus is provided, which includes a hanger including one or more power transmitter elements to transfer power from a first power source to a second power source implemented on a textile article capable of being hung on the hanger, where the power transmitter element is to transmit the power to a power receiver element implemented on the textile article.
In some aspects, a power transmitter element may transmit the power to the power receiver element over a contactless interface. The power transmitter element may wirelessly transmit the power to the power receiver element, for instance, the power transmitter element may inductively charge the second power source using the power receiver element. In such instances, the power transmitter element may include a first resonator and the power receiver element may include a second resonator, or the power transmitter element may include a power transmitter coil and the power receiver element may include a power receiver coil.
In some aspects, the textile articles which may be hung on the hanger may include a garment. The hanger may include a plurality of power transmitter elements to correspond to a plurality of different areas of any one of a variety of different garments in which a corresponding power receiver may be found in the garment.

In some aspects, the hanger may include one or more permanent magnets to attract another magnet or a metallic element in the textile article corresponding to the power receiver element. The power transmitter element may include a removable power transmitter element capable of being removed from and replaced on the hanger. In some instances, a hanger device may itself include a power source or power receiver to access the power to provide to the power receiver element. For instance, the power source may include a battery internal to the hanger. In some instances, the power source may be a source external to the hanger, and the power receiver may connect the hanger to the power source external to the hanger. For instance, the power receiver includes a cable. In cases where a battery is provided within the hanger, the battery is to be recharged by the power source external to the hanger.
In some aspects, the hanger further comprises a processor, memory, and a data transmitter to wirelessly send data to a data receiver element included in the textile article. The hanger may also, or instead, include a data receiver to wirelessly receive data from a data transmitter element included in the textile article. The hanger may be shaped as a clothes hanger with a portion to hang from a hanger rod or hook and another portion over which clothing may be draped, clipped, or otherwise hung on the hanger.
In some implementations, a textile article may be provided, which include a first power source; and a power receiver element, such as a receiver resonator, positioned on the textile article to correspond with a defined location on a hanger device, wherein the defined location corresponds to a power transmitter element on the hanger device, such as a transmitter resonator, configured to transfer power from a second power source to the first power source.
In some aspects, the power transmitter element includes a power transmitter coil and the receiver resonator comprises a power receiver coil. The power receiver coil may include a coil constructed from a fluidic wire. The power source may include a battery. The textile article may include circuitry to recharge the battery using the power received at the receiver resonator. The textile article may include one or more elements to physically align the receiver resonator to the transmitter resonator. The elements may include one or more magnets, which may couple with magnets on the hanger device to cause the power receiver element to align with one of the power transmitter elements on the hanger device.
In some instances, the textile article may include a garment. For instance, the garment may be embodied by such examples as an elastomeric athletic garment, a garment top (e.g., a shirt, blouse, bra, swimsuit top, coat, jacket, sweater, etc.), a head covering (e.g., a scarf, helmet, hat, cap, beanie, headband, etc.), a garment bottom (e.g., pants, skirt, shorts, underwear, swim bottoms, etc.), among other examples (e.g., industrial, athletic, or military uniforms, dresses, tunics, overalls, bodysuits, etc.).
