Abstract: A flexural pivot can include a plurality of flexure support members, each flexure support member having a plurality of flexure openings defined at least partially by a cantilevered extension portion. The flexural pivot can also include at least one flexure to rotatably couple the plurality of flexure support members to one another. The at least one flexure can have first and second flexible blades arranged in a cross configuration. The first and second flexible blades can be disposed in the flexure openings of the flexure support members, and the cantilevered extension portions, at least in part, can couple the first and second flexible blades to the flexure support members.

Abstract: A system includes a compound flexure having a frame, a flexure, and a post flexure. The frame has an axis, and the flexure is located within the frame. The flexure is movable relative to the frame, and the frame and the flexure form at least part of a monolithic structure. The post flexure extends along the axis and engages the flexure. The system also includes a device coupled to the flexure and configured to move with the flexure relative to the frame. The system further includes an actuator coupled to the flexure and configured to move the flexure and the device relative to the frame.

Abstract: A bi-directional spring member is mounted to a support platform, the bi-directional spring member being coupled to a payload. The bi-directional spring member includes a non-linear spring component having a rigid member enclosing at least a portion of a compliant planar member and a linear spring component. The compliant planar member flexes in a direction opposite a direction of low amplitude vibrational forces acting on the compliant planar member to reduce vibrational forces acting on the support platform and the linear spring member flexes to reduce high amplitude vibrational forces acting on the support platform.

Abstract: A reaction compensated tilt platform assembly comprises a support base, and a reaction mass, pivotally coupled to the support base. A tilt platform which can function as or support a mirror is pivotally coupled to the support base. At least two linear actuator coil assemblies are carried by the reaction mass. At least two linear actuator magnet assemblies are carried by the tilt platform and are disposable within the at least two linear actuator coil assemblies. The linear actuator magnet assemblies taper from a larger diameter toward a center of the magnet assembly to a smaller diameter toward an end of the magnet assemblies. Actuation of the linear actuator magnets results in pivotal movement of the tilt platform relative to the reaction mass.

Abstract: An apparatus includes a first interface platform and a second interface platform. One interface platform is configured to be coupled to a support structure, and the other interface platform is configured to be coupled to a device that operates at a temperature different than a temperature of the support structure. The apparatus also includes at least one intermediate stage platform and struts connecting the first and second interface platforms to the at least one intermediate stage platform. Top surfaces of the interface platforms may be substantially coplanar. At least a portion of the second interface platform can reside within an opening of the first interface platform. The struts can be arranged in a nested configuration having first and second sets of struts, where the second set is located within the first set. Each strut in the first set could be substantially parallel to an adjacent strut in the second set.

Abstract: According to one embodiment, an apparatus includes an optical sensor having one or more thermally sensitive components. The sensor is gimbal mounted on a space or air-borne vehicle and includes a heat sink component thermally coupled to the one or more thermally sensitive components via at least one heat strap and configured to at least passively receive and store thermal energy from the one or more thermally sensitive components without use of a motorized thermal energy transfer device. The apparatus also includes a radiator configured to receive thermal energy from the heat sink component and to dissipate thermal energy to an ambient environment. The radiator is disposed on a first side of an optical path of the sensor opposite a second side of the optical path on which the heat sink component is disposed. The heat sink component is configured to at least partially balance a center-of-gravity of the sensor.
