With respect to fig. 1-3, an embodiment of a charging and optical communication device 100 is depicted.
Generally, the device 100 includes a transmitter 200 and a receiver 300. The transmitter 200 includes a transmitter first end 210 and a transmitter second end 220, a laser 230, power management 240, a modulator 250, a diffuser (diffuser film)260, and a photon detector 270. The transmitter first end 210 includes a transmitter USB interface 212. The transmitter 200 receives external device power 482 and may communicate with one or more external devices via external device/device power communications 484. The transmitter 200 provides optical communication 284 to the receiver 300 and receives a laser/LED diode signal 373 from the receiver 300.
The receiver 300 includes a receiver first end 310 and a receiver second end 320, a receiver first PV cell 312, and a laser/LED diode 370 that emits a laser/LED diode signal 372. Receiver 300 sends out power two 382 and optical communication two 384. The receiver first PV cell 312 and the laser/LED diode 370 are located at the receiver first end 310. Receiver 300 receives optical communication one 284 from transmitter 200 and receives power one 282 from transmitter 200. The receiver laser/LED diode 370 emits a laser/LED diode signal 372 that is directed to the transmitter photon detector 270.
The device 100 may further include an adapter 500. The adapter 500 includes an adapter first end 510 and an adapter second end 520. Generally, the adapter 500 is fitted with the receiver 300 at the adapter first end 510, and further includes an adapter USB interface 522. The adapter 500, internally receives the power two 382 and the optical communication two 384 from the receiver 300 portion, and converts one or both of the power two 382 and the optical communication two 384 to a USB protocol via the USB interface 522 to provide one or more of the power two 382 and the optical communication two 384 via the USB hardware interface.
The transmitter 200 receives power, i.e., external device power 482, from one or more external sources, such as a standard wall outlet, a personal computer, or a laptop computer, and may be a wireless connection. External device power 482 is received at the transmitter USB interface 210. The transmitter USB interface 210 is a USB hardware interface and operates using the USB protocol. The transmitter power management module 240 receives power from the transmitter USB interface 210 and transfers power to the laser 230 and the modulator 250. Further, the transmitter power management module 240 controls the laser 230 via one or more drive circuits and/or controllers. The laser 230 converts electrical energy received from the power management module 240 into optical energy. The laser 230 emits light towards the diffuser 260, and the diffuser 260 diffuses or spreads the received light towards the receiver 200 to enable reception by the receiver first PV cell 312. In one embodiment, one or more waveguides are included to receive and transmit laser light.
The modulator 250, powered by the power management module 240, modulates the bi-directional optical communication function, receives input from an external source, such as a laptop computer, and outputs to the laser 230 to enable optical communication via the laser 230 output. Modulator 250 may modulate the laser light in any manner known to those skilled in the art, including amplitude modulation, phase modulation, and/or polarization modulation. In one embodiment, where device 100 is not configured to perform optical communications, modulator module 250 is not a component of device 100.
The photon detector 270 is located at the transmitter second end 220 and is positioned to receive the laser/LED diode signal 372 transmitted from the receiver laser/LED diode 370. The photon detector 270 communicates with the power management module 240 and provides a signal to the power management module 240 indicating the receipt or non-receipt of the laser/LED diode signal 372. In one embodiment, the power management module 240 operates the laser 230 (i.e., sends a signal to the laser 230 to activate and lase) only when the power management module 240 receives a signal from the photon detector 270, i.e., the laser/LED diode signal 372 has been determined to be received.
The receiver first PV cell 312 receives laser light from the laser 230 through the diffuser 260. In one embodiment, the receiver first PV cell 312 is located at the receiver first end 310, wherein the receiver first end 310 is configured as a male end to fit the female end of the transmitter second end 220. The receiver laser/LED diode 370 emits a laser/LED diode signal 372 that is directed to the transmitter photon detector 270. The function of the laser/LED diode signal is to establish communication between the transmitter 200 and the receiver 300 and to act as a safety device as previously discussed (i.e., to activate or deactivate the laser 230). In one embodiment, the receiver laser/LED diode 370 is placed adjacent to or beside or to the side of the receiver first PV cell 312. In one embodiment, the receiver laser/LED diode 370 is placed parallel to the outside surface of the receiver 300 at the receiver first end 310.
The receiver first PV cell 312 converts the received laser light into electrical power for output as electrical power two 382. The power output by the receiver 300 is provided at the receiver second end 320 and may comprise any format known to those skilled in the art, including 120 volts at 60 hertz and 230 volts at 50 hertz. In one embodiment, the power output by the receiver 300 is USB protocol.
In one embodiment, one or both of the transmitter USB interface 212 and the adapter USB interface 522 comprise any USB hardware interface known to those skilled in the art, including micro-USB, mini-USB, and standard USB hardware interfaces.
In one embodiment, device 100 has similar physical dimensions as a USB device known to those skilled in the art, such as a USB memory device.
In one embodiment, one or more interconnections between elements of device 100 include wireless USB.
In another embodiment, device 100 performs optical (i.e., laser-based) charging alone, wherein power provided by a first external device (e.g., laptop, personal computer, smartphone) is provided to a second external device (e.g., laptop, personal computer, smartphone).
In one embodiment, device 100 alone performs optical (i.e., laser-based) communication between a first external device (e.g., laptop, personal computer, smartphone) and a second external device (e.g., laptop, personal computer, smartphone).
In one embodiment, the device 100 includes its own power source, e.g., a battery such as a lithium battery, to power the laser and provide any set of functions disclosed above, e.g., charging and optical communication.
In one embodiment, the device 100 may operate in any one of three selectable modes: charge only, optical communication only, and simultaneous charge and optical communication.
Referring to fig. 1 and 2, fig. 3 provides a flow chart illustrating an example method of use of the charging and optical communication system 100. Generally, the method 600 begins at step 604 and ends at step 632.
In step 608 of the method 600, the device 100 is fitted to the external device 400 via the receiver first end 210. Device 100 receives external device power 482 and, in some embodiments, may communicate with an external device via external device/device power communication 484. External device/device power communications 484 may include on/off reception or non-reception of signals and power modulation signals, the latter of which is controlled by power management module 240 in some embodiments.
In step 612, the inquiry is made whether the device 100 receives a diode signal from a receiver. More specifically, the photon detector 270 of the transmitter 200, which is in communication with the power management module 240, provides a signal to the power management module 240 to indicate the receipt or non-receipt of the laser/LED diode signal 372 from the receiver 300. If the result of the query is yes or positive, such a signal has been received, the method 600 proceeds to step 616. If the result of the query is no or negative, the signal is not received and the method 600 proceeds to step 628.
At step 616, the laser 230 is activated by the power management module 240. Method 600 then proceeds to step 620.
At step 620, laser 230 transmits power and/or provides light-based two-way communication, as selected by the user or as configured by device 100. The method 600 then proceeds to step 624.
In step 624, the inquiry is made as to whether the device 100 continues to receive diode signals from the receiver. More specifically, the photon detector 270 of the transmitter 200, which is in communication with the power management module 240, provides a signal to the power management module 240 to indicate that a laser/LED diode signal 372 is or is not received from the receiver 300. If the result of the query is yes or positive, the receipt of such a signal continues and the method 600 proceeds to step 620. If the result of the query is negative or negative, the signal has ceased to be received, and the method 600 proceeds to step 628.
At step 628 of method 600, the laser 230 is deactivated by the power management module 240. Method 600 then proceeds to step 632, where method 600 ends.
