     FIELD 
       [0003]    The disclosure relates generally to remote charging of devices, such as, remote charging by photovoltaic (PV) cells, infrared (IR) illumination, audio signals, and LEDs such as laser LEDs to charge devices such as watches, jewelry, car panels, headphones and phones. 
       BACKGROUND 
       [0004]    Electronic devices require regular power charging. Existing means to charge electronic devices, such as watches and jewelry, require a contacted (ie physical) solution for charging, e.g. through USB, electrical cord, etc. There currently exist no solutions that provide charging in a contactless manner, eg that are wireless. A solution that allows non-physical connection enables charging without physical connection, as well as other interactions with a device, e.g. software updates and configuration updates. These and other needs are addressed by the various aspects, embodiments, and/or configurations of the present disclosure. 
         [0005]    By way of providing additional background, context, and to further satisfy the written description requirements of 35 U.S.C. §112, the following references are incorporated by reference in their entireties: U.S. Pat.

Photon detector  270  is in communication with transmitter/charger  200  and may provide a signal to transmitter/charger  200  indicating receipt or non-receipt of laser/LED diode signal  372 . In one embodiment, the transmitter/charger  200  only operates the laser  230  transmitter/charger LED transmitter  260  (that is, sends a signal to the transmitter/charger LED transmitter  260  to activate and emit laser light) when the transmitter/charger  200  is in receipt of a signal from the photon detector  270  that a laser/LED diode signal  372  has been affirmatively received. 
         [0051]    In one embodiment, target device solar cells  312  receive laser light emitted from LED transmitter  260  (in some embodiments after passing through lens  290 ) by way of a diffuser film.

         [0056]    In one embodiment, the transmitter/charger  200  solely performs optical (i.e. laser-based) communication between the transmitter/charger  200  and the target device  300 , or between the external device  400  and the target device  300  by way of the transmitter/charger  200 . 
         [0057]    In one embodiment, the transmitter/charger  200  comprises its own power supply, such as a battery such as a lithium battery, so as to power the laser and provide any set of functions disclosed above, such as charging and optical communication. 
         [0058]    In one embodiment, the transmitter/charger  200  may operate in any of three selectable modes: power charging only, optical communications only, and both power charging and optical communications. 
         [0059]    In one embodiment, the transmitter/charger  200  outputs bi-directional optical communications  284  with the target device  300 , wherein the optical communications comprise communication protocols optimized for selectable parameters, e.g. physical separation geometries between the transmitter/charger  200  and the target device  300  or capabilities of the target device  400 . More specifically, the specialized or optimized communication protocols may be tuned to charge optically communicate with a smartwatch or other piece of jewellery in close optical proximity to the transmitter/charger  200 . 
         [0060]    With specific reference to  FIG. 1B , further details of the system  100  are provided. External device  400  outputs power, such as electrical power, by way of external device power  482  to transmitter/charger  200 . Transmitter/charger  200  receives external device power  482  and also receives a modulated optical communication signal emitted or supplied by the targeted device, that is, the optical communication three  384  signal emitted by the receiver modulator  392  of the target device  300 . In one embodiment, to include that of  FIG. 1B , the lens  290  and the transmitter/charger  200  form part of a physical enclosure. Lens  290  receives one or more of power one  282  and optical communication one  284 , and transmits one or more of power two  292  and optical communication two  294  to target device solar cells  312 . The target device solar cells  312  convert the received power two  292  (i.e. light or optical energy) to electrical energy to charge battery  390 . The target device solar cells  312 , in combination with a target device receiver, demodulate the received modulated optical signal and transmit the demodulated signal to the receiver modulator  392  of the target device  300 . 
         [0061]    With reference to  FIGS. 1A-C ,  FIG. 2  provides a flow chart illustrating an exemplary method of use of the charging and optical communication system  100 . Generally, the method  500  starts at step  504  and ends at step  544 . The method  500  can include more or fewer steps or can arrange the order of the steps differently than those shown in  FIG. 2 . 
         [0062]    At step  508  the light transmitter/charger  200  receives power from external device  400 . At step  512 , the light transmitter/charger  200  receives a modulated communications signal from the external device  400 . (In some embodiments, the light transmitter/charger  200  generates its own modulated communications signal). At step  516 , the light transmitter/charger  200  transmits one or both of the power signal (e.g. light energy, such as an LED emitted optical power signal) and the modulated (optical) communications signal to the target device  300 . (In some embodiments, the light transmitter/charger  200  performs signal processing to the received modulated communications, for example, noise reduction processing). At step  520 , the target device  300  receives one or both of the power signal and the modulated communications signal. 
         [0063]    At step  532 , a query is made as to whether power was received by the target device. If the answer is Yes, the power (optical signal, i.e. optical power signal) is provided to the solar (e.g. PV) cells of the target device and the battery of the target device is charged; the method then continues to step  536 . If the answer to the query is No, the method proceeds to step  532 . 
         [0064]    At step  532 , a query is made as to whether a first (optical) communication signal was received by the target device. If the answer is Yes, the method continues to step  536  wherein the received communications signal is demodulated and the method proceeds to step  540 . If the answer is No, the method proceeds to step  540 . 
         [0065]    At step  540 , the target device transmits a second (optical) communications signal as desired. The method ends at step  544 . 
         [0066]    With focus on  FIG. 3 , a representation of another embodiment of the charging and optical communication system is provided. Generally, a laser and diffusive fiber charging, illumination, and communication device with PV array is provided. This embodiment may be particularly useful to provide an optical charging solution through the use of laser LEDs for car panels, and/or communication and data transfer through fiber (or LED or laser), and/or illumination to the panel. In the embodiment of  FIG. 3 , the LED transmitter  260  of the transmitter/charger  200  emits (optical) power one  282  and/or optical communication one  284  through a diffusive fiber  280 , which in turn emits optical energy and/or optical communications signal(s) to and/or within solar cell arrays  312  so as to emit optical communication two  294  signal. Stated another way, the laser/LED signal goes through a diffuser fiber, which optically charges PV arrays and/or illuminated panels; a fiber optical communication and/or a bus structure may also be provided. Note that the diffuser fiber diffuse or spreads received light so as to be received by PV arrays/solar cells  312 . In one embodiment, one or more wave guides are provided to receive and transmit the laser light. 
         [0067]    With focus on  FIGS. 4A-B , in yet another embodiment, an optical activation trigger switch  500  using finger tapping is disclosed. Generally, light interruption in any form, i.e. finger, blockage, etc in order to wake or activate an electronic device, is utilized. In dark environments, the principle of frustrated total internal reflection is employed. Problems addressed by this embodiment comprise: products often have buttons for power and activation, but this technology may eliminate the need for a button mechanism.  FIG. 4A  provides a representation of an optical trigger switch  500  mechanism which may serve as a component of the charging and optical communication system  100  disclosed above, wherein the trigger mechanism is in a first state.  FIG. 4B  provides a representation of an optical trigger switch  500  mechanism which may serve as a component of the charging and optical communication system, wherein the trigger mechanism is in a second state. 
         [0068]    Trigger switch  500  comprises a light source  510 , such as a laser/LED, which emits an optical signal  540 , a surface barrier  520  comprising an internal reflective surface  524  and exterior surface  528 , and a host device  530  which is engaged with or contains the light source  510  and the surface barrier  520 . The trigger switch may operate in at least a first state (depicted as  FIG. 4A ) and a second state (depicted as  FIG. 4B ). In either state, the light source  510 , disposed within the host device  530 , emits an optical signal  540  directed at the internal reflective surface  524 . In the first state of  FIG. 4A , the optical signal  540  reflects from the internal reflective surface  524  and back into the host device  530 . In one embodiment, the surface barrier is disposed on or near a boundary of the host device  530 , such as on or parallel to a side or edge of the host device  530 . In the first operational state of the trigger switch, the optical signal  540  is substantially or completely reflected back into the host device; this is termed “total internal reflection.” In this state, the optical signal  540  travels up and back down from the surface barrier  520  and may be considered to complete a signal or provide an “on” switch position. (Note that in  FIG. 4A  the optical signal  540  is shown passing through a lens prior to receipt by a PV cell.) In contrast, in the second state of the trigger switch  500  depicted in  FIG. 4B , an external source  550  (here, a human finger) engages the surface barrier exterior surface  528 , wherein the optical signal  540  is unable or significantly restricted in reflecting from the internal reflective surface  524 . In such a situation, the optical signal  540  is termed as scattering or to have encountered “frustrated total internal reflection.” In such a situation, the optical signal  540  travels up and then scatters from the surface barrier  520  and may be considered to provide an “off” switch position. In some embodiments, a sensor is provided so as to establish a selectable threshold optical signal  540  strength (to, for example, the lens shown) wherein above the threshold value the switch is considered “on” and below which the switch is considered “off.”
