FIG. 1 ; numbers in the 200 series refer to features originally found inFIG. 2 ; and so on. - The present disclosure relates generally to techniques for wireless charging. Specifically, the techniques described herein include a wireless power transmitting coil disposed within an ergonomic product such as a hand-operated input device, a support for a wrist, palm, hand, or other parts of the human body, and the like. A user of a wirelessly chargeable may spend several hours a day at a computing device. The user may interact with the computing device via a hand-operated input device. For example, a user may use a mouse to interact with a computing device. Therefore, the techniques described herein include disposing a wireless power transmitting (Tx) coil at or within a hand-operated input device. Disposing the wireless Tx coil within the hand-operated input device may enable convenient charging of a wearable device, such as a watch, having a wireless power receiving (Rx) coil while a user is using the hand-operated input device. In some cases, the Tx coil may be disposed in any ergonomic support structure where a user may more often place a hand, arm, ankle, and the like. For example, the Tx coil may be disposed in an ergonomic support in a computer, a table either as integrated or as an accessory, ergonomic support in a automobile. Ergonomic support may be a feature configured to guide a body member to a position, wherein coupling between a Tx coil and Rx coil is increased.
- A hand-operated input device, as referred to herein, may include a human input device including a computing device configured to interact with a user at, or near, a hand of the user. In some cases, the hand-operated input device may include a keyboard, a mouse, and the like. A hand-operated input device may be referred to herein as a hand-operated input device, an input device, or any combination there. In some cases, the wireless power Tx coil may be disposed in a platform associated with the hand-operated input device. For example, a keyboard may include a pad or platform wherein the wireless power Tx coil may be disposed within the pad.

FIG. 1 is block diagram of a PTU to provide power to a PRU, wherein a magnetic component protrudes from the PTU. A PTU 102 may couple to a PRU 104 via magnetic inductive coupling betweenresonators arrow 110. Theresonator 106 may be referred to herein as aTx coil 106 of thePTU 102. Theresonator 108 may be referred to herein as anRx coil 108 of the PRU 104. - As discussed above, the
Tx coil 106 may be disposed in an input device as indicated by thedashed outline 111. For example, theinput device 111 may be a computer mouse, touch pad, or similar input device configured to detect input such as movement of a user's hand in coordinates, upon detection of pressure from the user's fingers, and the like. The PRU 104 may be disposed within a wearable computing device indicated at thedashed circle 112. Thewearable computing device 112 may be configured to be worn near a user's hand. For example, the wearable device may be a bracelet, a watch, a ring, a glove, or any other wearable computing device that will be near theinput device 111 during use of theinput device 111. In other words, the techniques described herein include a Tx coil, such as theTx coil 106, disposed within an input device, such as theinput device 111, which may enable convenient charging of a wearable computing device, such as thewearable computing device 112. In some cases, the Txcoil 106 may be used to power up a wearable low power input/sensor device that does not have a battery such as a battery 124 of thewearable device 112, but a capacitor/super capacitor for energy storage. - The PRU 104 may include a
controller 114 configured to detect current received at theRx coil 108 resulting from an inductive coupling between theTx coil 106 and theRx coil 108. In some cases, thecontroller 114 may be configured to initiate a wireless data broadcast via a wireless transmission component. - The wireless data transmission component may be Bluetooth Low Energy (BLE)
module 116 in some cases. In some cases, the wireless data transmission component may be integrated as operations of thecontroller 114, aload modulation circuit 118, a direct current to direct current (DC to DC)converter 120, or any combination thereof, wherein the data transmission may be indicated by patterns in the load modulation. The wireless data broadcast may transmit data during operation of theinput device 111. For example, health data such as a user's heart rate, temperature, and the like may be monitored during use theinput device 111. In some cases, monitoring health data may be used to remind the user to shift movement or perform physical action to meet health related goals. Other types of data may be transmitted based on functions of thewearable computing device 112. - As illustrated in
FIG. 1 , the DC toDC converter 120 provides a DC output to a battery 124, or another current/power consuming component. The DC TODC converter 120 may convert DC received as a result of the inductive coupling of theTx coil 106, theRx coil 108, and therectifier 122. - The PTU 102 may include a
BLE module 126 configured to communicate with theBLE module 116. ThePTU 102 may also include acurrent sensor 128, acontroller 130, apower amplifier 132, a DCTO DC converter 134, anoscillator 136, and amatching network 138. Thecurrent sensor 128 may be an ampere meter, a volt meter, or any other meter configured to sense load variations occurring due to inductive coupling between thePTU 102 and another object, such as the PRU 104. Thecurrent sensor 128 may provide an indication of load change to acontroller 130 of thePTU 102. Thecontroller 130 may power on thepower amplifier 132 configured to receive direct current (DC) from the DC TODC converter 134, and to amplify and oscillate the current. Anoscillator 136 may oscillate the power provided at a given frequency and amatching network 138 may be used to match the amplified oscillation provided to theresonator 106 of thePTU 102. - The block diagram of
FIG. 1 is not intended to indicate that thePTU 102 and/or thePRU 104 are to include all of the components shown inFIG. 1 . Further, thePTU 102 and/or thePRU 104 may include any number of additional components not shown inFIG. 1 , depending on the details of the specific implementation. For example, in some cases, thePTU 102 may include multiple Tx coils, such as theTx coil 106. In this scenario, coupling to theRx coil 108 to one of the Tx coils may be based on a strength of the coupling between theRx coil 108 and one of the multiple Tx coils. -
FIG. 2 is an illustration of a perspective view of an example wireless power transmitting coil disposed within a platform of a hand-operated input device. In the example 200 ofFIG. 1 , an input device, such as theinput device 111 ofFIG. 1 , may include a wireless power transmitting coil, such as theTx coil 106. A wearable computing device, such as thewearable computing device 112 ofFIG. 1 , may include a wireless power receiving coil, such as the wirelesspower Rx coil 108 ofFIG. 1 . - As illustrated in
FIG. 2 , theRx coil 108 of thewearable computing device 112 may be received atinput device 111 such that wireless coupling may be performed between theRx coil 108 and theTx coil 106 of the input device. InFIG. 2 theTx coil 106 is disposed substantially parallel to asurface 202. -
FIG. 3 is an illustration of a perspective view of another example wireless power transmitting coil disposed within a platform of a hand-operated input device. In example 300, theRx coil 108 ofFIG. 1 is disposed along a curve of thewearable device 112. In comparison toFIG. 2 wherein theRx coil 108 is disposed along a flat planar surface, theRx coil 108 illustrated inFIG. 3 may exhibit a reduced magnetic coupling for wireless charging as portions of theRx coil 108 may be farther away from theTx coil 106. Therefore, in some cases, theTx coil 106 may be shaped to mimic a shape of thewearable computing device 112. Further, even if some portions of theRx coil 108 are farther away from theTx coil 106, the disposition of theTx coil 108 in theinput device 111 may increase a duration magnetic coupling during use of theinput device 111 thereby conveniently charging thewearable computing device 112. -
FIG. 4 is an illustration of a perspective view of an example wireless power transmitting coil disposed at an angle within a platform of a hand-operated input device. In example 400, theTx coil 106 is formed at an angle to thesurface 202 upon which theinput device 111 is operated, as indicated by the dashedcurve 402. Further, in this example 400, theRx coil 108 is formed along a loop of thewearable computing device 108. A coupling may occur between theangled Tx coil 106 and theRx coil 108. Theangle 402 may increase magnetic coupling in the example 400 illustrated inFIG. 4 . In some cass, theangle 402 may be formed to align with a shape of a user's hand support, wrist support, palm support, and the like. -

In example 500, theTx coil 106 is formed at an angle that is substantially perpendicular to the surface upon which theinput device 111 is configured to operate, as indicated by the dashedcurve 502. In this scenario, the substantiallyperpendicular angle 502 may increase magnetic coupling between theTx coil 106 and theRx coil 108. Similar to example 400, theRx coil 108 in example 500 is formed along a loop of thewearable computing device 108, as illustrated inFIG. 5 . -
FIG. 6 is an illustration of a perspective view of an example wireless power transmitting coil as a component of a power propagation device disposed within a platform of a hand-operated input device. In some cases, an input device, such as theinput device 111 ofFIG. 1 may include a power propagation device indicated at 602. Thepower propagation device 602 ma include including theTx coil 106 and anRx coil 604 configured to receive power from another Tx coil (not shown) disposed at thesurface 202, under thesurface 202, or any combination thereof. - In some cases, the
input device 111 may passively provide wireless power via wireless power repeating. In some cases, ferromagnetic sheets or other elements may be included to optimize coupling between theTx coil 106 and theRx coil 108. In some cases, theinput device 111 may repeat wireless power received at theRx coil 602, as well as charge theinput device 111 via the power received. In some cases, thepower propagation device 602 may be implemented with a phase shifting component that may couple theRx coil 604 to theTx coil 106. The phase shifting component may ensure that an impedance inversion is generated by thepower propagation device 602. In some cases, the phase shifting component may enable a constant current source to be provided from thePTU 102 regardless of the strength of a magnetic coupling between theRx coil 108 of thewearable device 112 and theTx coil 106. Examples of thephase shifting component 116 may include an impedance transformer, a transformer, a quarter wavelength transmission line, any combination thereof, among others. In general, a passive coupler structure in an input device and/or ergonomic platform may be used to guide magnetic fields to an area where a wearable device is typically disposed. -
FIG. 7 is an illustration of a perspective view of an example wireless power transmitting coil as a component of an ergonomic platform. Anergonomic platform 702 may be useful in charging thewearable device 112 via coupling between theTx coil 106 and theRx coil 108. In some cases, theergonomic platform 702 may include asurface 704 configured to receive a portion of thewearable device 112 due to a shape of thesurface 704. Therefore, thewearable device 112 may be conveniently charged. In some cases, theergonomic platform 702 may include multiple Tx coils includingTx coil 106, as well asTx coil 706 andTx coil 708. In this scenario, theRx coil 108 may couple to any of the Tx coils 106, 706, and/or 708. -

Theergonomic platform 802 may include multiple Tx coils includingTx coil 106 andTx coil 804. The disposition of Tx coils, such as one or more of the Tx coils 106 and 804, may enable convenient charging of a wireless charging system in a wearable device configured to be worn on or near a body part configured to be used near theinput device 111. -
