1. An optical communications and charging system comprising:
- a transmitter/charger configured to receive a first communications signal and a power signal from an external source, the transmitter/charger comprising a light source, wherein the transmitter/charger is configured to operate in different selectable modes including a power charging only mode, an optical communications only mode, and both a power charging and optical communications mode, and wherein the light source is configured to transmit the first communications signal and/or the power signal based on a particular selected mode of the different selectable modes;
a lens configured to receive the first communications signal and/or the power signal; and
a target device comprising;
a battery; and
a PV cell in communication with the battery, the target device configured to receive, at the PV cell, the first communications signal and/or the power signal transmitted by the light source, the target device configured to transmit a second communications signal to the transmitter/charger;
wherein the power signal received by the target device enables the PV cell to charge the battery, and wherein the first communications signal received by the target device is demodulated via the PV cell.

10. A method of optical communications and charging, the method comprising:
-
providing an optical communications and charging system comprising; a transmitter/charger configured to receive a first communications signal and a power signal from an external source, the transmitter/charger comprising a light source, wherein the transmitter/charger is configured to operate in different selectable modes including a power charging only mode, an optical communications only mode, and both a power charging and optical communications mode, and wherein the light source is configured to transmit the first communications signal and/or the power signal based on a particular selected mode of the different selectable modes;
a lens configured to receive the first communications signal and/or the power signal; and
a target device comprising a battery and a PV cell in communication with the battery, the target device configured to receive, at the PV cell, the first communications signal and/or the power signal transmitted by the light source, the target device configured to transmit a second communications signal to the transmitter/charger;engaging the transmitter/charger charging device with an external source; providing a first communications signal and/or a power signal to the transmitter/charger from the external source; transmitting the first communications signal and/or the power signal from the light source of the transmitter/charger to the target device based on the particular selected mode of the different selectable modes; and determining whether the first communications signal and/or the power signal comprises the power signal; wherein, upon determining that the transmitted first communications signal and/or the power signal comprises the power signal, the PV cell receives the power signal and the battery is charged; and wherein, upon determining that the transmitted first communications signal and/or the power signal comprises the first communications signal, the first communications signal received by the target device is demodulated via the PV cell. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
