Latest Patents

One of Chun F Chen's latest patents is a control circuit for a motor-driven door operator. This invention includes a motor-driven mechanism that allows a door to move between open and closed positions in response to an improved control circuit. The control circuit is designed to initialize the motor's operation sequence upon power connection or restoration after an outage. It features obstruction detection circuitry that stops or reverses the motor if an obstacle is encountered during door movement. Additionally, time delay circuitry prevents premature stopping or reversing of the motor due to inertia. The design allows for manual activation to stop or reverse the door's movement, enhancing user control. When nearing the closed position, timer circuitry energizes the motor for a predetermined time or until resistance activates the obstruction detection circuitry, ensuring safe operation. Maximum run-time circuitry is also included to limit the motor's energization time.
