Abstract
A method for supplying power to detected devices coupled to a conductive backplane includes: supplying a plurality of sensing signals at a plurality of transmit impedance values to the conductive backplane; analyzing a plurality of return signals received from the conductive backplane, the return signals corresponding to the sensing signals; detecting the presence of a sink device coupled to the conductive backplane based on the analyzed return signals; and supplying power from a power supply to the sink device via the conductive backplane after detecting the presence of the sink device.
