ACTIVE COMMUNICATIONS BUS POWER HARVESTER FOR DIFFERENTIAL SIGNAL COMMUNICATION SYSTEM

摘要

A balanced differential signal communication system having at least two data lines connecting multiple nodes in series, each node comprising a signal generator for applying signals to the data lines that produce a controllable differential voltage across the data lines; a rechargeable storage device for receiving electrical energy from the data lines to charge the storage device; at least one device coupled to the storage device for receiving electrical energy from the storage device; and a controllable converter coupling the data lines to the storage device for controlling the charging and discharging of the storage device with power captured from the data lines.
