Specifically, systems and methods to provide charging through laser or optical means and to provide optical communications are presented. Even more specifically, in one embodiment, the systems and methods comprise standard USB interfaces, USB protocols and USB connectors.

First claim

What is claimed is:

1. An optical charging and communications device comprising:
a transmitter having a first end and a second end, the transmitter configured to receive power from an external source, the transmitter comprising a power module, a power charging laser, and a diffuser film, wherein the transmitter includes a detector disposed at the second end; and
a receiver having a first end and a second end, the receiver including an emitter disposed at the first end of the receiver, wherein the emitter is configured to operatively interconnect with the detector defining a connected state between the transmitter and receiver, the receiver comprising an array of two or more PV cells;
wherein the power module controls the laser;
wherein the power charging laser emits a laser light, wherein the laser light is diffused by the diffuser film, exits the diffuser film, and is sent over the air to the array of two or more PV cells, the array of two or more PV cells being disposed opposite the power charging laser and diffuser film in the connected state between the transmitter and receiver; and
wherein the receiver outputs a device power output.

2. The device of claim 1 , wherein the power module receives power from an external source.

3. The device of claim 2 , wherein the received power is received via a USB connector, and wherein the USB connector is disposed at the first end of the transmitter.

4. The device of claim 1 , wherein the emitter further comprises a laser/LED diode and the detector further comprises a photon detector disposed opposite the laser/LED diode in the connected state, the photon detector configured to receive a connection signal from the laser/LED diode.

5. The device of claim 4 , wherein the power charging laser of the transmitter emits the laser light only when the photon detector receives the laser/LED diode connection signal and the device is in the connected state.

6. The device of claim 1 , further comprising a modulator configured to manage optical communications between the transmitter and the receiver.

7. The device of claim 6 , wherein the modulator modulates optical communications output by the laser.

8. The device of claim 7 , wherein the device power output is of USB protocol.

9. The device of claim 8 , further comprising:
an adapter configured to receive the device power output from the receiver and output the device power output via a USB connector disposed at an end of the adapter.

10. A method of optical charging comprising:
providing an optical charging device comprising: i) a transmitter having a first end and a second end, the transmitter configured to receive power from an external source, the transmitter comprising a power module, a laser, a diffuser film and a photon detector, wherein the transmitter includes a detector disposed at the second end, and ii) a receiver having a first end and a second end, the receiver including an emitter disposed at the first end of the receiver, and wherein the emitter is configured to operatively interconnect with the detector defining a connected state between the transmitter and receiver, the receiver comprising an array of two or more PV cells and a laser/LED diode, the array of two or more PV cells being disposed opposite the laser and diffuser film in the connected state between the transmitter and receiver, wherein the photon detector is configured to receive a connection signal from the laser/LED diode when the device is in the connected state;
engaging the optical charging device with an external power source;
providing power to the charging device from the external power source;
interconnecting the transmitter and receiver via mating the detector with the emitter;
activating the laser only upon receipt of the laser/LED diode connection signal, wherein the laser emits a laser light;
the laser light diffusing by the diffuser film;
the diffused laser light exiting the diffuser film;
sending the diffused laser light over the air to the array of two or more PV cells; and
outputting a device power output from the receiver.

11. The method of claim 10 , wherein the received power is received via a USB connector, and wherein the USB connector is disposed at the first end of the transmitter.

12. The method of claim 10 , wherein the charging device further comprises a modulator configured to manage optical communications between the transmitter and the receiver.

13. The method of claim 12 , wherein the modulator modulates optical communications output by the laser.

14. The method of claim 13 , wherein the charging device power output is of USB protocol.

15. The method of claim 14 , wherein the charging device further comprises an adapter configured to receive the device power output from the receiver and output the device power output via a USB connector disposed at an end of the adapter.

16. An optical charging and communications system comprising:
a transmitter having a first end and a second end, the transmitter configured to receive power from an external source, the transmitter comprising a power module, a power charging laser, and a diffuser film, wherein the transmitter includes a detector disposed at the second end; and
