Abstract: In a method for superimposed conveyance of data and electrical power, a first switch can cycle to convey the electric power and data from a first device. Binary digits of the data from the first device can be represented by transitions, of a voltage at a node of a second device, between a first voltage and a second voltage. A second switch can cycle to convey data from the second device. Binary digits of the data from the second device can be represented by transitions, of a current through a component of the first device, between being less than a threshold and being greater than the threshold. A voltage regulator of the second device can provide, in response to the voltage at the node being within a range of voltages that includes the first voltage and the second voltage, the electrical power to one or more components.
