ABSTRACT:
A system and method for transferring power using a data communications signal line. The data communications signal line is in a high impedance powerless state when idle. A main device is electrically coupled to the data communications signal line. The main device generates and transmits a signal on the data communications signal line. The signal includes power generation and non-power generation characters. A peripheral device is electrically coupled to the data communications signal line. The peripheral device has a functional unit arranged to perform a desired function for the peripheral device. A power conversion module is electrically coupled to the data communications signal line and receives the signal. The power conversion module converts power from the received signal to a form suitable for storage. A controller is in electrical communication with the functional unit and the power conversion module. The controller receives the power generation and non-power generation characters, strips the power generation characters from the signal and transmits the non-power generation characters to the functional unit.
