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 flexural pivot is disclosed. The flexural pivot can include a first flexure support member, a second flexure support member rotatably coupled to the first flexure support member for relative rotation about a first axis, and a third flexure support member rotatably coupled to the second flexure support member for relative rotation about a second axis. In addition the flexural pivot can include a plurality of cross blade flexures rotatably coupling the flexure support members to one another. Each cross blade flexure can have first and second flexible blade units that have flexible blades arranged in a cross configuration. The flexible blade units can have blade supports disposed at opposite ends of the flexible blades to facilitate coupling the flexible blade units to the flexure support members. The flexible blade and the blade supports of each flexible blade unit can form a monolithic structure.

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 method includes generating a first varying electromagnetic field using a first voice coil of a first actuator. The method also includes repeatedly attracting and repelling a first magnet of the first actuator based on the first varying electromagnetic field. The first voice coil is connected to a first piston of a compressor, and the first magnet is connected to an opposing second piston of the compressor. Attracting the first magnet narrows a space between the pistons, and repelling the first magnet enlarges the space between the pistons. The method may further include generating a second varying electromagnetic field using a second voice coil of a second actuator and repeatedly attracting and repelling a second magnet of the second actuator based on the second varying electromagnetic field. The second voice coil may be connected to the second piston, and the second magnet may be connected to the first piston.

Abstract: A multi-axis flexure device can include a first support base, a second support base, and a central coupler. The multi-axis flexure device can also include a first flexure device rotatably coupling the first support base and the central coupler to one another to facilitate rotation about a first axis, and a second flexure device rotatably coupling the second support base and the central coupler to one another to facilitate rotation about a second axis. Each flexure device can include a first flexure, a second flexure, and a flexure coupler coupled to the first and second flexures. The first flexure and the second flexure of the first flexure device can, respectively, be coupled to the first support base and the central coupler. The first flexure and the second flexure of the second flexure device can, respectively, be coupled to the second support base and the central coupler.

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 shutter assembly comprises a base coupled to a photosensor assembly, a flexure device supported by the base, and a shutter arm rotatably coupled to the base via the flexure device. An actuation mechanism is coupled to the shutter arm via the flexure device, and is operable, upon application of an electric field, to rotate the shutter arm from a first position to a second position (or to a third position) to manage light relative to a photosensitive device of the photosensor assembly. Upon rotation of the shutter arm to the second position, the flexure device stores energy such that, upon removal of the electric field, the flexure device releases the stored energy to return the shutter arm to the first position. A keeper magnet can be provided to maintain the shutter arm in the second (actuated) position, so that the electric field can be removed while the keeper magnet maintains a magnetic force to keep the shutter arm in the second position.
