Title: Thomas William Shoaff: Innovator in Sensing Technology
Introduction
Thomas William Shoaff is a notable inventor based in Warrenville, IL (US). He has made significant contributions to the field of sensing technology, holding a total of 3 patents. His work focuses on developing innovative solutions that enhance the efficiency and effectiveness of smoke detection systems.
Latest Patents
One of Shoaff's latest patents is the Miniature Photoelectric Sensing Chamber. This invention features a low-profile, low-volume smoke chamber that displaces a light source, such as a light-emitting diode or laser diode, and a sensor, such as a photodiode or phototransistor, to the exterior of the sensing volume. The design results in a symmetrical sensing volume that can be coupled to symmetrical input/output ports via a generally U-shaped flow path. The two-part sensing chamber housing consists of a lower cylindrical base portion and an upper cylindrical cover portion that slideably engage one another. The upper portion is equipped with grooves to suppress reflections and collect dust, while openings at the exterior end can be filled with a screen. This design ensures an acceptable signal-to-noise ratio and response rate while excluding insects and other non-smoke-related particulate matter.
Another significant invention is the Aspirated Detector. This aspirated-type detector includes a housing with an internal ambient condition sensing region and a sensor carried within. The housing is perforated with ambient atmosphere inflow ports, and a fan or similar device lowers the pressure in the internal region, producing a positive inflow of adjacent, external ambient atmosphere into the sensing region. The fan can also be modularized and may incorporate control circuitry for supervisory or signal processing purposes.
