    摘要： A seal assembly configured for sealing a dynamic shaft includes an elastic seal member disposable in sealing communication with the dynamic shaft. The seal assembly further includes a coil spring and a shape memory alloy element. The coil spring is disposed in contact with the elastic seal member and configured for applying a compressive force to the elastic seal member. The shape memory alloy element is configured for applying pressure to the coil spring to thereby augment the compressive force.

    摘要： A baffle controller for moving a baffle disposed within an HVAC outlet housing between an open position and a closed position to control airflow through an HVAC outlet in a vehicle includes a Shape Memory Alloy (SMA) actuator that is controlled and actuated by an electrical signal. The SMA actuator rotates a main lever that rotates a valve plate. The valve plate is attached to the baffle such that the baffle rotates with the valve plate. The baffle controller may include a position biasing device that increases a position holding ability of the baffle controller, and a cut-off switch that interrupts the electrical signal to the SMA actuator to prevent over-rotating the baffle.

    摘要： A method for controlling welding forces of a weld tip to a work piece during a vibration-welding process includes positioning an Active Material (AM) element adjacently to a welding interface, and varying a property of the AM element to regulate the welding force. The AM element may be disposed between the weld tip and a weld face thereof, or between the work piece and an anvil. The property may be varied as a function of heat generated by the welding process. A property of each of a plurality of AM elements may be independently and selectively varied via an energy source, or passively. A vibration welding system includes a weld tip and an AM element connected adjacently to a welding interface. The system regulates a welding force applied by the weld tip to a work piece during the welding process by varying a property of the AM element.

    摘要： Active material actuator assemblies are provided that enable simplified control systems and faster actuator cycle times. A movable member is provided that has multiple active material components operatively connected to it. The active material components are separately selectively activatable for moving the movable member. Movement of the movable member via activation of a first of the active material components triggers activation of the second active material component to further move the movable member. Alternatively or in addition, previously activated active material components are protected from undesired stretching during activation of another active material component or, when desired, an active material component may be reset via activation of another of the active material components in order to prepare it for subsequent activation.
