    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,

    Abstract: A system includes a device, a support structure, and a flexure bearing configured to connect the device to the support structure. The flexure bearing includes an outer hub and an inner hub, where the hubs are configured to be secured to the support structure and to the device. The flexure bearing also includes multiple sets of flexure arms connecting the outer and inner hubs. Each set of flexure arms includes symmetric flexure arms. The flexure bearing could include three sets of flexure arms positioned radially around a central axis of the flexure bearing and having a spacing of about 120°. Each flexure arm can follow a substantially curved path between the outer hub and the inner hub. The symmetric flexure arms in each set can be configured such that twisting of one flexure arm in one set is substantially counteracted by twisting of another flexure arm in that set.

    Abstract translation: 系统包括设备，支撑结构以及被配置为将设备连接到支撑结构的弯曲轴承。 挠性轴承包括外毂和内毂，其中毂被构造成固定到支撑结构和装置。 挠性轴承还包括连接外毂和内毂的多组挠曲臂。 每组挠曲臂包括对称的弯曲臂。 挠曲轴承可以包括三组位于径向上围绕挠曲轴承的中心轴线并具有大约120°的间隔的挠曲臂。 每个弯曲臂可以沿着外毂和内毂之间的基本弯曲的路径。 每组中的对称弯曲臂可以被配置成使得一组中的一个挠曲臂的扭转通过在该组中的另一个挠曲臂的扭转基本抵消。
