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 lockable lateral adjuster mechanism comprises a platform with a channel carried by a base. A cam has an eccentric head that is pivotally disposed in the channel. The cam has a stem extending through the channel and into a counter bore in the base. The platform is laterally displaceable with respect to the base as the cam pivots. A countersunk interface is disposed between the eccentric head and the channel. A fastener extends through the cam to the base, and secures the cam, and thus the platform, to the base, and applies an axial load on the countersunk interface along an axis of rotation of the cam.

Abstract: A triangular frame metering structure includes three side beams and three end pieces each connected between two of the side beams. Each end piece top and bottom is configured for connection of support loads, with all support loads connecting to the metering structure at the top or bottom of one of the end pieces. Secondary mirror focusing mechanisms mounted on the end piece tops support pairs of secondary mirror struts. Strut mounts on the end piece bottoms provide connections to pairs of primary mirror struts, base struts, and instrument struts. All support loads connected to the metering structure are thus connected only to the corners of the metering structure and are connected at a same radial distance from a central longitudinal axis. The metering structure has reduced mass with high stiffness for supporting large aperture telescopes.

Abstract: Components within a cryocooler are scaled and/or configured for operation at a CMG operating frequency (e.g., 100 Hz) rather than at 30 to 70 Hz, matching the exported disturbances of control moment gyroscopes on the same platform and reducing line-of-sight jitter for electro-optic infrared focal plane array sensors. The smaller piston working volume and other reduced component sizes allow the cryocooler to be smaller and lighter than designs operating at lower frequencies. Combined with an advanced regenerator suitable for the higher frequency operation, the cryocooler has improved cooling efficiency over such lower frequency designs.

Abstract translation: 低温冷却器内部的部件按比例缩放和/或配置为在CMG工作频率（例如，100Hz）而不是在30至70Hz的条件下操作，与控制力矩陀螺仪在同一平台上导出的扰动相匹配，并减少视线 电光红外焦平面阵列传感器的抖动。 较小的活塞工作容积和其他减小的部件尺寸允许低温冷却器比在较低频率下工作的设计更小更轻。 结合先进的再生器适用于较高频率的操作，低温制冷机在这种较低频率设计中具有改进的冷却效率。

Abstract: A solar rejection system includes an enclosure for housing a sensor, and a movable sunshade. The housing has an opening or aperture for admitting light to the sensor, and the sunshade is moved as needed to prevent harmful solar illumination of the sensor. The sunshade may be a flat panel. The sunshade panel is mounted to a hinge that is located on one side of a large diameter bearing that allows the shade to be rotated around the aperture of the sensor to always prevent the sun from illuminating the aperture. The hinge allows the shade to be tilted to either allow the sensor to see further off axis without obscuration or to block the sun when it moves in front of the sensor. Full closure of the sunshade on its hinge allows it to also function as an aperture door, blocking the opening or aperture.

Abstract: A flexural pivot can include a plurality of flexure support members, each flexure support member having a plurality of flexure openings and a plurality of wells each in fluid communication with a respective flexure opening. 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 coupling material deposited in the flexure openings can couple the first and second flexible blades to the flexure support members.

Abstract: A precision adjustment fastener mechanism comprises a base, a platform, and a locking push-pull fastener assembly. The base has a first aperture and the platform has a second aperture. The fastener assembly is disposed within the second aperture. The fastener assembly comprises a clamping fastener having a portion positioned in the first aperture, a sleeve having a third aperture extending along an axis of the sleeve. The clamping fastener is positioned within the third aperture. The sleeve comprises a first portion moveable relative to a second portion along the axis. The first portion and the second portion each comprise outer threads. An axial displacement portion separates the first and second portions and transmits a torque between the first and second portions. The axial displacement portion facilitates movement of the first and second portions to bind threads of the first and second portions with the threads of the platform,
