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 first and 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 first port, and a first temperature compensator for adjusting the position of the first 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 fluidic lens device capable of providing variable focal power with reduced optical aberration is disclosed. The device includes a lens member and an actuator. The lens member comprises one or more elastic optical surfaces, a support member in communication with the optical surfaces, and a fluid-filled chamber. The optical surfaces have a high value of elastic modulus, reducing coma and other aberrations associated gravity and acceleration. The support member may provide a compliant fluid seal and allow the edges of the optical surfaces to pivot, reducing spherical and other aberrations. One or more piezoelectric ring-bender actuators may provide the force required for compressing the support ring and deflecting the optical surfaces. The actuators may be configured to provide the fluidic lens device with reduced sensitivity to changes in temperature.

摘要： In one embodiment of the present invention, a shape memory alloy ("SMA")-actuated helical spring brake comprises a rotatable member (106) and a helical wrap spring (108) arranged concentrically about the rotatable member. The spring has a first spring end and a second spring end and includes a number of turns that are biased radially inward and are configured to frictionally engage the rotatable member. The turns permit rotation of the rotatable member in a first direction and inhibit rotation in a second direction. The SMA-actuate helical spring brake also includes an anchor point (114) coupled to the second spring end, and an SMA actuator (102) having an output drive member coupled to the first spring end. The SMA actuator is configured to, for example, deflect the first spring end to permit the rotatable member to rotate.
