Latest Patents

One of his latest inventions is a traffic control system and method of operation. This system utilizes a vehicle detector that comprises a flux gate magnetometer with vertical and horizontal sensing coils positioned within a roadway. The ambient levels of the earth's magnetic field are sensed by the magnetometer to establish reference levels. 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, either vertical or horizontal levels exceeding threshold values also trigger a signal. Both vertical and horizontal levels must fall below threshold levels 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 used by traffic signal controlling computers.

Another significant invention by Ward is a programmable paging encoder. This device includes a microcomputer with a look-up table containing code formats for popular paging systems. It features an energy conservation mechanism that keeps the microcomputer in an off state except when activated by a keyboard input. The microcomputer is programmed to contain tone and space data for various paging formats and routines for converting input data, such as a telephone number, into a tone and space code for the selected paging format.
