摘要： A valve system including a number of shape memory alloy (“SMA”)-actuated valves for controlling the flow of fluids is disclosed as is a variety of types of SMA-actuated valves and methods of operation. In one embodiment, a valve system includes a housing having a substantially closed cavity as well as a second port for communicating a fluid. Further, the valve system includes a first SMA actuator configured to control the position of the first seal to vary fluid flow through the firs port, and a first temperature compensator for adjusting the position of the seal by an amount proportional to temperature. A second SMA-actuated valve, driven by either a unidirectional or a bidirectional SMA actuator, controls the position of the second seal to vary fluid flow through the second port, and a second temperature compensator for adjusting the position of the second seal by another amount proportional to temperature.

摘要： A method of controlling a shape memory alloy actuator includes applying power to a shape memory alloy actuator. A measured actuation parameter is obtained from the shape memory alloy actuator. An operational characteristic parameter is derived based upon the power and the measured actuation parameter. An actuation state parameter is identified from the operational characteristic parameter. The actuation state parameter is used to modify the control of the shape memory alloy actuator.

摘要： A fluidic lens may have a reservoir at least partially bounded by a first optical surface and a second optical surface. A fluid fills a volume of the reservoir. A piston is configured to contact a portion of the first or second optical surface from outside the reservoir. One or more of the first optical surface or second optical surface is configured to deform as a result of a change in a pressure applied to the fluid or a change in contact between the piston and the first or second optical surface. A rim may be disposed outside the reservoir and configured to contact and provide additional deformation to one or more of the first or second optical surface.

摘要： A fluidic optical device may include a first optical surface that includes an deformable material and a second optical surface that includes a rigid material. An optical fluid disposed between first and second optical surfaces and an actuator is disposed in communication with first optical surface. Activation of actuator results in a deformation of first optical surface and displacement of optical fluid. The deformation and displacement result in a change in an optical property of the device. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

摘要： A fluidic lens may have a transparent window member, a transparent distensible membrane, an inner ring between the window member and membrane, and a top ring disposed such that the membrane is between the piston ring and the inner ring. A layer of liquid may be stored between the window member, the inner ring and the membrane. The top ring may be adapted to apply a liquid displacement force to the membrane in a direction perpendicular to a plane of an aperture of the inner ring to cause a change in a radius of curvature of the membrane. The membrane may be pre-tensioned prior to assembly with the other components.
