Abstract: A resettable sensor assembly includes a housing having a longitudinal axis and defining a cavity therein. The assembly includes a divider disposed within the cavity and in contact with the housing, at least one electrical contact disposed within the cavity and extending through the divider, and a pin reversibly translatable within the cavity along the axis. The assembly includes at least one actuator element disposed within the cavity and abutting the housing. The element is configured for translating the pin along the axis between a first position wherein the pin contacts the electrical contact and a second position wherein the pin is spaced apart from the electrical contact. The actuator element is formed from a shape memory alloy that is transitionable between an austenite crystallographic phase and a martensite crystallographic phase in response to a thermal activation signal to thereby translate the pin between the first and second positions.

Abstract: An adjustable bumper, adapted for supporting closure panels on a vehicle, is described. The bumper incorporates a shape memory polymer portion, which may be readily permanently reshaped by the steps of: heating above its transition temperature, deforming by application of a load, and cooling, while still under load, below its transition temperature. This behavior is exploited to enable adjustment of the adjustable bumper so that it may provide the desired closure panel support while accommodating vehicle to vehicle variations in the fit of the closure panel and the vehicle body.

Abstract: A system for controlling motion of a shape memory alloy (SMA) actuator includes a damper operatively connectable to the SMA actuator and having a movable portion that moves with the SMA actuator when the SMA actuator contracts during electrical activation. An electronic switch is operatively connectable to the SMA actuator and to the damper. The electronic switch has an open position preventing electrical power flow to the SMA actuator, and a closed position permitting electrical power flow to the SMA actuator. A biasing element applies a biasing force that urges the electronic switch to the closed position. The damper overcomes the biasing element to move the switch to the open position only when velocity of the movable portion equals or exceeds a predetermined threshold velocity, and to return to the closed position when the velocity of the movable portion falls below the predetermined threshold velocity.

Abstract: An inlet, positioned to access the flow of air passing around and under a moving vehicle, draws in air which is conveyed through a duct and discharged to cool a brake on a vehicle. The inlet has a closure so that access of cooling air may be denied when the brake temperature is less than a predetermined temperature and opened only when the brake temperature exceeds that predetermined temperature. The closure is operated by a temperature-operated actuator. In embodiments the actuator may be suitably positioned to sense a temperature representative of the brake temperature and to incorporate a thermally activated phase change, active or smart material preselected to operate the inlet closure when the sensed brake temperature exceeds the predetermined temperature.
