Title: Roy Stockdale: Innovator in Security Technology
Introduction
Roy Stockdale is a notable inventor based in Huntington, NY (US). He has made significant contributions to the field of security technology, holding a total of 13 patents. His innovative work primarily focuses on intrusion detection systems and seismic sensor apparatus.
Latest Patents
One of Stockdale's latest patents is an intrusion detection system that employs vibration sensors arranged in a series loop. This system consists of first and second wires, which are terminated by a terminating impedance. A processing circuit is coupled to the wires, supplying a square wave biasing waveform and a DC voltage determined by the terminating impedance. By detecting the magnitude of the DC level, the processor can determine if the loop has been opened or shorted, or if any sensor in the loop has been activated due to an intrusion. This system effectively uses two wires for both power supply and sensing output signals from the monitored loop.
Another significant patent is a seismic sensor apparatus. This device consists of a central annular member with an inner conductive periphery, positioned around a center post located in a housing. The center post features four extending surface slots into which tines or upstanding flanges associated with first and second contact members are inserted. This design allows the sensor to be mounted in four distinct positions, providing great flexibility for installers.
