摘要： Malfunction or failure of mechanical, electrical and electro-mechanical equipment, for example equipment used in manufacturing operations, is often preceded by an increase in the operating temperature of at least some portion of the equipment. A temperature-sensitive, active material-containing actuator is pre-selected to operate at a pre-determined temperature indicative of impending equipment failure and placed in thermal contact with the equipment. If the equipment achieves the pre-selected temperature the actuator signals this by displaying a flag or providing some other passive visual indication. Alternatively, or additionally, the actuator may issue an electrically-powered alert including visual or audible alerts or a wireless communication. Selected actuators are based on smart materials including shape memory alloys (SMA), shape memory polymers (SMP) and paraffin wax, all of which may be adapted to operate over a temperature range sufficient to encompass the expected range of pre-determined temperatures.

摘要： A method of reducing an initial stress on a cable includes stretching the cable to a first length to thereby define the initial stress. The cable has a central longitudinal axis, and includes a plurality of wires each twisted around the axis and formed from a shape memory alloy transitionable in response to a signal between a first state wherein each of the wires has a first temperature-dependent length, and a second state wherein each of the wires has a second temperature-dependent length that is less than the first. After stretching, the method includes activating the alloy by exposing the alloy to the signal such that the alloy transitions from the first to the second temperature-dependent state. Concurrent to activating, the method includes elongating the cable to a second length that is greater than the first to define a second stress on the cable that is less than the first.

摘要： A shape memory alloy (SMA) actuator includes an SMA element and a flexible outer coating or layer. The element is respectively activated by a heating source. The layer surrounds the element, and enhances the heat transfer characteristics of the element to increase the speed of the actuation cycle. The nominal geometry and/or thermal conductivity may be altered during an activation phase, and may include discrete elements oriented with respect to the element, and partially embedded in the layer. An end gripper assembly may be used to cause the layer to move in concert with the element during a phase transformation. An electro-mechanical system includes the cooling source and the actuator. A method includes connecting the actuator to a load, activating the element using the heating source, and deactivating the element using a cooling source or free/ambient air.
