Abstract: A wireless modular power transfer system includes electric power modules and RF converter circuitry within the electric power modules that meets voltage and power characteristics of the electric power modules. Sensor data is processed to determine a wireless power transfer path. An electric power module is established as a power source by aligning RF converter circuitry as a transmitter, and an electromagnetic field is established as a wireless power transfer area. An electric power module is established as an electric load by aligning RF converter circuitry as a receiver. Power transfer between the electric power modules is controlled through the wireless power transfer area.

Abstract: A power control device includes a multiple socket-outlet, a power plug and a power supply control circuit. The control circuit includes a power output unit, a first relay and a second relay, a first capacitor, a mechanical switch, an electronic switch and a connector connected to the host of a computer to receive a first voltage. The mechanical switch is turned on to supply power to the multiple socket-outlet, the first relay is closed, the power output unit outputs a working voltage for charging the first capacitor, the electronic switch is turned on, the second relay is closed. If the connector is turned off, the electronic switch is turned off, and the second relay is turned off so that the the multiple socket-outlet is closed.
