  • Patent number: 7929125
    Abstract: Embodiments of a gimbaled system with an optical coudé path and method for transferring data are generally described herein. In some embodiments, the gimbaled system includes optical coudé path to provide a data communication path with a gimbaled payload, an on-gimbal communication laser to transmit modulated camera data via the coudé path, and an off-gimbal communication detector to detect the camera data received via the coudé path. In some embodiments, the optical coudé path may include at least two mirrors to provide a bi-directional communication path through an azimuth axis and an elevation axis of the gimbaled payload.

  • Publication number: 20090314890
    Abstract: A nose cone formed from a shape memory alloy (SMA) having a recoverable strain of at least 2% collapses about the dome for storage, deploys at launch to protect the sensor dome and reduce drag during atmospheric flight and is shed to allow sensing for terminal maneuvers. The SMA is shape-set at elevated temperatures in its Austenite phase with a memorized shape having a radius of curvature greater than that of the sensor dome to reduce aerodynamic drag. The temperature is reduced and the SMA collapsed to conform to the curvature of the sensor dome within the recoverable strain for storage. A first mechanism is configured to return the collapsed SMA to its memorized shape at launch or prior to going supersonic. In one embodiment, the SMA is stored below its Martensite finish temperature in a temperature-induced Martensite phase in which case the mechanism heats the SMA above the Austenite finish temperature to return the material to its memorized shape.

  • Publication number: 20080203633
    Abstract: A spring including a wire having an elasticity by which the wire is compressible by an external force to a first position at which first and second ends thereof of are separated by a first distance and when the force is removed or an electrical current applied, the wire is extensible in response to an internal spring force to a second position at which the wire is substantially straight. A spring assembly is disclosed including a plurality of inventive wires cross-coupled with a support structure consisting of a plurality of coaxial rings. In the assembly, the wires extend parallel to an axis through a center of the rings.
