| 摘要 |
A register used in a Heating Ventilation and Cooling (HVAC) system, with an electro- magnetic linear actuator is disclosed herein. The register includes: a physical supporting frame (register body), a housing (for power source, radio and electronic circuitry), a power source, a wireless radio, other electronic circuitry, a means-to-open and close the register and a means-to- detect the open or closed state of the register. The use of an electro-magnetic linear actuator to open and close the register, rather than a more conventional electric motor, solenoid/spring or magnet/spring approach, provides a cost-effective, mechanically reliable and environmentally resilient solution. |
