Latest Patents
Sarkar's latest patents include an electromechanical relay system and a light curtain system with system and watchdog microcontrollers. Both inventions are designed to sense the intrusion of an opaque object in a light plane. Upon detecting such an intrusion, the systems initiate a machine-stopping sequence before the object can make contact with the operating machine. The systems utilize a SYSTEM microcontroller and a WATCHDOG microcontroller, which work together to control the output device of the light curtain switch. These microcontrollers perform integrity checks on both hardware and software, ensuring reliable operation. The WATCHDOG microcontroller further evaluates the SYSTEM microcontroller's performance by sending a false intrusion signal to a photosource, verifying the initiation of the machine-stopping sequence. This combination of electronic, mechanical, and optical modules enhances reliability and accuracy while reducing sensitivity to spurious signals.
