Abstract
The present invention is directed to a computer system having novel circuitry for coupling peripheral cards to a power line network. In this regard, the computer includes a switching power supply having coupling circuitry for coupling an electrical signal with a power line, a filter circuit electrically connected to the coupling means for receiving an electrical signal from the coupling means and filtering the received signal, and an amplifier circuit electrically connected to the filter circuit for amplifying the filtered signal. The computer system also includes at least one peripheral circuit (e.g., PC card). An infrared transmitter is coupled to the amplifier circuit for transmitting an infrared signal. Finally, the computer includes an infrared receiver coupled to the peripheral circuit for receiving the scattered infrared signal. In accordance with another embodiment of the invention, a power line adapter is provided for communicating signals between a power line and a computer. In accordance with yet another aspect of the invention, a method is provided for coupling a power line with a peripheral card in computer system. The method operates by coupling an electrical signal, within a switching power supply, with the power line, transmitting the electrical signal through an infrared transmitter disposed at the on the switching power supply, diffusing the signal transmitted from the infrared transmitter, and receiving the diffused signal through an infrared receiver disposed on a peripheral card.
