Title: Glenn F Cooper: Innovator in Optical Smoke Detection
Introduction
Glenn F Cooper is a notable inventor based in Hingham, MA (US), recognized for his contributions to smoke detection technology. He holds 2 patents that showcase his innovative approach to enhancing safety through advanced detection systems.
Latest Patents
One of Cooper's latest inventions is the Optical Particle Detector. This device features a photoelectronic smoke detector with walls surrounding a dark chamber, allowing smoke to enter while blocking light. Light is directed from a source along a path to a limited area of the chamber wall. A first photocell detects light scattered by particles in the path and also captures background light from the chamber wall. A second photocell is designed to receive background light primarily from the limited area. The first cell generates a signal in response to both background and particle-scattered light, while the second cell produces a signal corresponding to background scatter. These cells, preferably photovoltaic photodiodes, are connected in opposition within a circuit, making the output largely independent of background light.
Another significant invention by Cooper is the Latching Alarm Smoke Detector. This optical smoke detector utilizes a clock-pulsed light source and photodiodes that respond to smoke-scattered light. It includes an alarm-initiating logic circuit that delays the alarm activation while multiple smoke samples are sensed. Once the conditions are met, the logic circuit latches into an alarm state, ensuring timely alerts in case of smoke detection.
