Latest Patents

Among his latest innovations is a traffic control system and method of operation. This invention features a vehicle detector that utilizes a flux gate magnetometer equipped with vertical and horizontal sensing coils positioned within a roadway. The system establishes reference levels based on the ambient levels of the earth's magnetic field. Deviations from these levels are evaluated by a microprocessor, which produces a vehicle arrived signal when the vertical component of sensed perturbations exceeds a threshold. In an alternate mode, the system activates when either vertical or horizontal levels exceed threshold values. Both levels must fall below the thresholds to determine a departure in either mode. Vehicle arrival and departure events are encoded as NRZ data packets, transmitted by an edge-fired antenna as FM modulated signals. A remote multi-channel receiver processes the received data and provides signals for traffic signal controlling computers.

Another significant invention by Soulliard is a touch tone decoder. This programmable tone decoder is designed for standard bell system DTMF tone pairs. It comprises an integrated DTMF receiver and a means for programming a sequence of digits, which are compared to the output of the DTMF receiver. The decoding mechanism provides an output for an exact comparison of the complete sequence, indicating the reception of a proper telephone code sequence.
