Latest Patents
Hung-Sun Oh holds a patent for a "Two position rotary actuator incorporating DC solenoid." This invention provides a method and apparatus for controlling a ventilation damper unit. The actuator is designed to rotate the output coupling, which in turn rotates the damper shaft to open the damper. After approximately 95 degrees ±3 degrees of output coupling rotation, a limit switch is activated. A DC solenoid equipped with a full way bridge rectifier extends to a brake rotor, locking the damper into position. This design also reduces electrical consumption by shutting off power to the actuator motor assembly. In the event of a complete power failure, such as during a fire and smoke emergency, the DC solenoid is spring returned, allowing the damper to close and prevent the flow of air and smoke, thereby starving a fire of oxygen.
