OPTICAL POWER SUPPLY SYSTEM, WAKEUP METHOD AND OPTICAL COMMUNICATION DEVICE ON THE RECEIVING SIDE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18036314 titled 'OPTICAL POWER SUPPLY SYSTEM, WAKEUP METHOD AND OPTICAL COMMUNICATION DEVICE ON THE RECEIVING SIDE

Simplified Explanation

The patent application describes an optical power supply system that uses an optical signal to transmit power from a power supply side device to a power receiving side device. The power supply side device includes a sleep control unit that generates a sleep cancellation signal to wake up certain functional units in the power receiving side device. This sleep cancellation signal is then superimposed on the optical signal and transmitted to the power receiving side device. The power receiving side device has a detection unit that detects the sleep cancellation signal and a control unit that switches the functional units from a sleep state to an activated state in response to the detected signal.

• Power supply system that uses optical signals for power transmission
• Sleep control unit in the power supply side device generates a sleep cancellation signal
• Power supply control unit superimposes the sleep cancellation signal on the optical signal
• Detection unit in the power receiving side device detects the sleep cancellation signal
• Control unit in the power receiving side device switches functional units from sleep to activated state

Potential Applications

• Optical power supply systems for various devices and equipment
• Power transmission in remote or hard-to-reach locations
• Power supply in environments where traditional electrical wiring is not feasible

Problems Solved

• Efficient power transmission without the need for traditional electrical wiring
• Ability to remotely control and activate functional units in power receiving devices
• Reduction in power consumption by enabling sleep states in functional units when not in use

Benefits

• Simplified power supply system using optical signals
• Improved energy efficiency by enabling sleep states in functional units
• Remote control and activation of devices and equipment

Original Abstract Submitted

An optical power supply system including a power supply side optical communication device that supplies power using an optical signal for power supply, and a power receiving side optical communication device that is driven by power obtained from the optical signal for power supply transmitted from the power supply side optical communication device, in which: the power supply side optical communication device includes a sleep control unit that generates a sleep cancellation signal for canceling sleep states of some functional units included in the power receiving side optical communication device, and a power supply control unit that superimposes the sleep cancellation signal on the optical signal for power supply and transmits the superimposed signal to the power receiving side optical communication device; and the power receiving side optical communication device includes a detection unit that detects the sleep cancellation signal superimposed on the optical signal for power supply, and a control unit that performs control to switch a functional unit from a sleep state to an activated state in response to the sleep cancellation signal detected by the detection unit.
