摘要： 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.

摘要： A flexural pivot is disclosed. The 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Aspects and embodiments are generally directed to modular imaging spectrometer assemblies and methods of operation thereof. In one example, a modular imaging spectrometer assembly includes foreoptics to receive electromagnetic radiation and produce a real exit pupil, the foreoptics having a first f-number, a first imaging spectrometer to receive and disperse the electromagnetic radiation into a first plurality of spectral bands at a first image plane, the first imaging spectrometer having a second f-number independent of the first f-number, a second imaging spectrometer separated from the first imaging spectrometer, the second imaging spectrometer to receive and disperse the electromagnetic radiation into a second plurality of spectral bands, the second imaging spectrometer having a third f-number independent of the first f-number, and at least one slit aperture positioned to receive the electromagnetic radiation from the real exit pupil and direct the electromagnetic radiation to the first and second imaging spectrometers.

摘要： An apparatus includes a first piston and an opposing second piston, where the first and second pistons are configured to move inward to narrow a space therebetween and to move outward to enlarge the space therebetween. The apparatus also includes a first voice coil actuator having (i) a first voice coil connected to the first piston and (ii) a first magnet connected to the second piston. The apparatus may further include a second voice coil actuator having (i) a second voice coil connected to the second piston and (ii) a second magnet connected to the first piston. Each voice coil actuator may be configured to apply equal and opposite forces on or against the first and second pistons.

摘要： A linear spring member having an annular region with a first thickness connected in series by cylindrical regions having a second thickness, wherein the first thickness is less than the second thickness. Outer portions of adjacent annular regions are coupled together by a first cylindrical region and inner portions of adjacent annular regions are coupled together by a second cylindrical region such that the effective spring rate of the bi-directional spring device increases symmetrically as it is displaced in either compression or tension.
