Abstract: A method of testing a SMA element includes connecting the SMA element to a validation tool, and applying an electrical current to the SMA element over a test cycle. A resistance of the SMA element during the test cycle is measured, while the electrical current is being applied. The measured resistance of the SMA element during the test cycle is correlated to an estimated strain value of the SMA element during the test cycle. A temperature of the SMA element during the test cycle is estimated. A stress in the SMA element during the test cycle is estimated from a stress predicting grid, using the estimated strain value and the estimated temperature of the SMA element during the test cycle. The proper functionality of the SMA element may be determined based on the estimated stress in the SMA element.

Abstract: Fit and finish methods using shape memory polymers (“SMP”) are disclosed herein. In an example of the fit and finish method, a first part and a second part are positioned adjacent to one another such that a shape memory polymer in a temporary shape is adjacent to a gap between the first part and the second part. The SMP is heated to a switching temperature of the SMP, which causes the SMP to initiate conversion to a permanent shape so that the SMP extends into the gap to close the gap between the first part and the second part.

CPC classification number: G01N27/041
Abstract: A sensor system includes a housing defining a cavity, an actuator formed from an alloy transitionable between first and second states, a plunger attached to the actuator, and a resilient member configured for translating the plunger within the cavity. The plunger is not translatable during a first condition in which a coating of debris is disposed on the housing as the alloy transitions between the first and second states to define a first stress on the actuator. The plunger is translatable during a second condition in which the housing is substantially free from the coating as the alloy transitions to define a second stress on the actuator that is less than the first stress. The alloy transitions from the first to the second state at a first transformation temperature during the first condition, and at a second transformation temperature that is less than the first temperature during the second condition.

Abstract: A reconfigurable bi-stable device includes an elastically deformable panel laterally disposed between and connected to one or more mounting members directly or indirectly connected to opposing ends of the panel, with the panel maintained under compressive force along at least one vector extending between the opposing ends. The compressive force deforms the panel into a one of two stable deformed positions, with the device disposed such that the panel may be moved between each of the two stable deformed positions by application of manual force to one of two opposing faces of the panel. A first shape memory alloy (SMA) or piezo actuator member is connected to the panel, the actuator member being capable of moving the panel from a first one of the two stable deformed positions to a second one of the two stable deformed positions.

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.
