    摘要: A system for protecting an emitter/receiver device, including a cover and an active material actuator operable to selectively cause the cover to move between default protective and open positions, wherein the actuator includes at least one active material element, such as an SMA wire configured to cause the retraction of the cover and present a heating net when activated, and an activation signal source, and preferably further including at least one pulley and/or jack mechanism configured to redirect a displacement force vector, synchronization means, an antagonistic element for biasing the cover towards the protective or open position, and a controller presenting overheating protection through control logic.
