Electronically addressable document receptacle with A-polar connectivity

Abstract

An electronically addressable a-polar document receptacle identification circuit has first and second terminals adapted to be connected to a two conductor data bus for supplying data signals to the terminals and for receiving responses from the circuit. The circuit has a two phase diode bridge circuit with first and second nodes connected to the first and second terminals. The diode bridge circuit is connect to the data signal input of a circuit microcontroller having an output connected to the first and second nodes for furnishing response signals to the nodes. The associated receptacle can be a file folder removably received in a file cabinet or a notebook binder removably received on a cabinet shelf. The circuit will function correctly regardless of the orientation of the terminals with respect to the data bus conductors so a file folder or a notebook binder can be installed in either one of two possible orientations without affecting the functionality of the circuit.
