Title: Marvin D. Laymon: Innovator in Detection Systems and Transducers
Introduction
Marvin D. Laymon is a notable inventor based in Milpitas, CA (US). He holds a total of 4 patents that showcase his contributions to the fields of detection systems and transducer technology. His innovative work has significantly impacted various applications, particularly in security and sensing technologies.
Latest Patents
One of Laymon's latest patents is the "Capacitance Intrusion Detection System." This system is designed for use with metal objects insulated from the ground. It features a circuit that cyclically charges and discharges the object at a low frequency, typically less than 500 Hz. The system integrates the charge on the object to develop a DC voltage proportional to its capacitance. It includes an AC-coupled integrating network and a bandpass filter that detects changes in capacitance caused by intruders, activating an alarm when an intrusion occurs. Additionally, tamper alarm circuits are incorporated to detect unauthorized disconnection or attempts to defeat the system.
Another significant patent is the "Dual Line Electret Transducer." This low-cost line transducer consists of a pair of electret-covered conductors twisted together to form longitudinal helices. These conductors are mechanically coupled to a medium that transmits mechanical forces transversely. Changes in the conductor-electret spacing due to mechanical disturbances generate electrical signals that are processed to indicate the occurrence of the disturbance. This design improves sensitivity to low-frequency disturbances while reducing undesired hum and noise.
