DISCHARGE CYCLE COMMUNICATION
First Claim
1. An apparatus comprising a circuit, the circuit electrically coupled to a line, wherein the circuit is configured to:
- receive a direct current signal over the line, the direct current signal having a period, wherein the period comprises a charge cycle and a discharge cycle, the direct current signal is generated from a charging of the line in the charge cycle and a cessation of the charging of the line in the discharge cycle, and the line fails to fully discharge for at least a portion of the discharge cycle; and
close a switch in the discharge cycle to transmit data over the line, the closure of the switch configured to discharge the line to an extent greater than in absence of a closure of the switch.

Abstract
In one embodiment, a system may be provided that includes a circuit that is electrically coupled to a line. The circuit generates a direct current signal on the line, where the direct current signal has a period that includes a charge cycle and a discharge cycle. The circuit charges the line in the charge cycle and ceases to charge the line in the discharge cycle in order to generate the direct current signal. The line fails to fully discharge for at least a portion of the discharge cycle. To receive data from the line, the circuit detects a variation in a discharging of the line in the discharge cycle.
