Identification of Moving Vehicles

Each one of a large number of vehicles is uniquely identified while moving past a stationary point.

Electrical contacts mounted on a stationary post along a railroad track brush against an identification unit mounted on the journal box of a railroad car wheel.

The identification unit consists of alternate layers of conductive and resistive material mounted on an insulator. The contacts brush against the conductor faces, each two adjacent contacts giving electrical access to one layer of resistive material.

Each resistive layer has any one of ten ohmic values, so that a number of layers represents a decimal number unique to the railroad car carrying the identification unit.

Recognition devices are housed in the stationary post for sensing the values of the resistive layers traversed by the contacts.

Since each car carries a unique combination of resistive layers, the recognition indicates the decimal number identifying the passing railroad car.
