Abstract: A latching actuator capable of repeated operation in a cryogenic, remote, or difficult-to-access environment, capable of enduring many cycles without user intervention or maintenance, capable of latching in a fixed position without consuming additional power, or to operate independent of external environmental conditions. In selected embodiments, a latching actuator may comprise an expansion chamber that houses a working substance capable of undergoing a phase change, a logic mechanism, a biasing assembly, and an output pin. In one embodiment, a wax motor may provide the motive force to toggle a latching mechanism. An actuator may be capable of positioning an output pin in two or more discrete latching positions and may be used to create a thermal connection between two structures, to engage or disengage a clutch, or to position an optical element in an optical instrument. An actuator may also be used as a launch lock apparatus.

Abstract: A two-axis, optical mount provides two flexural elements monolithically and homogeneously formed of a single material with, and interconnecting, three rigid segments. Between each pair of rigid segments, beginning with the first and second, a set of extensions is formed to have a cross section that permits simple, easy, independent adjustment therebetween. Likewise, a flexural element exists between the second and third rigid elements. Meanwhile, the rigid elements have section moduli sufficiently great as to be orders of magnitude larger than the flexural stiffness or section modulus of the flexural elements, thus providing flexures that operate in the elastic mode and introduce no joint type accuracy errors in adjustment.

Abstract: An apparatus, system, and method are disclosed for modifying thermal connections. An actuator motivates a thermal connector. In one embodiment, the actuator is configured as a wax actuator that motivates the thermal connector in response to melted wax. The thermal connector contacts a first body to form a thermal connection between the thermal connector the first body. A thermal link conducts heat through the thermal connection. In one embodiment, the thermal link conducts heat between the first body and a second body. In addition, the actuator may separate the thermal connector from the first body and stop the transport of heat.
