Latest Patents
One of Schofield's latest patents is the "Solid State Self-Checking Relay." This invention features a failsafe solid-state relay that prevents failure in a closed circuit condition. The relay includes a main switch connected in series with a load and voltage source, which responds to relay opening and closing signals. A secondary switch operates in opposition to the main switch, ensuring that if the main switch fails to open, the load is short-circuited, and a fuse is blown to maintain the relay in an open circuit condition. Self-checking circuits are integrated to ensure the relay remains in a safe state during any circuit failure.
Another significant patent is the "Presence Detecting System with Self-Checking." This invention focuses on systems that utilize beams of radiant energy, such as light beams, to detect the presence of individuals or objects within a designated area. The system incorporates self-checking mechanisms to verify that the detection system is functioning correctly, enhancing reliability and safety.
