摘要： A method of controlling and/or predicting the remaining useful life of an active material actuator, such as a shape memory alloy wire, includes obtaining historical actuation data of an inherent system variable, such as electrical resistance, over a secondary variable, such as time, determining a normal operating envelope having upper and lower bounds based on the data, determining a current profile for a given actuation cycle, and comparing the shape of the current profile to the envelope to determine an out-of-bounds event.

摘要： Methods for varying seal force in active seal assemblies for doors employ active materials that can be controlled and remotely changed to alter the seal effectiveness, wherein the active materials actively change modulus properties such as stiffness, or a combination of modulus and shape in response to an activation signal. In this manner, in seal applications such as a vehicle door application, door opening and closing efforts can be minimized yet seal effectiveness can be maximized.
