Latest Patents
Among Halsey's latest patents is the Hybrid Radar Receiver. This device features an antenna array that receives input signals containing radar signals from emitters. Each element of the array outputs an analog signal on a dedicated data channel, equipped with activatable A/D converters. A specialized hardware circuit determines when a radar pulse is received, activating the A/D converters to generate digital signals. This technology enhances the identification of signal emitters through sophisticated algorithms.
Another significant invention is the Firefighter Locator with Activator. This device is designed to work in conjunction with a firefighter's self-contained breathing apparatus (SCBA). It includes a pressure sensor that monitors the air line pressure. When the SCBA air tank valve is opened, the pressure activates a signal emitter, allowing base stations to track the firefighter's location. The system also features user-operated reset buttons and a shutoff circuit to ensure safe operation.
