    Abstract: A method of testing a shape memory alloy (SMA) actuated device includes cyclically operating the device. The method further includes determining a number of cycles in a functional life of the device based on observations of the device during the cyclical operation. The functional life is a range of consecutive cycles of operation of the device beginning with a first cycle during which the device performs within a specified limit. The functional life is immediately followed by a cycle during which the device performs outside of the specified limit. The method still further includes applying a progressive substitution sub-process to identify an opportunity to increase the number of cycles in the functional life of the device.

    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: 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. Some pre-determined temperature, greater than the highest normal operating temperature of the equipment, is presumed or known to be indicative of impending equipment failure if no remedial action is taken. A resettable, temperature-sensitive device, containing a shape memory alloy actuator, pre-selected to operate at the pre-determined temperature, is disclosed. The device is placed in thermal contact with the equipment. If the equipment achieves the pre-determined temperature, the shape memory alloy actuator causes the device to display a flag or provide some other passive visual indication. Alternatively, or additionally, the actuator may trigger an electrically-powered alert including visual or audible alerts or a wireless communication.

    Abstract: A support system includes a support, a root magnet, an object, and a cover magnet. The root magnet is fixedly attached to the support. The cover magnet is fixedly attached to the object. The root magnet and the cover magnet are configured to be magnetically attracted to one another such that the object is magnetically attached to the support when the root magnet and the cover magnet are aligned with one another in an attachment arrangement. The root magnet and the cover magnet are configured to magnetically repel one another such that the object is detached from the support when the root magnet and the cover magnet are unaligned with one another in a detachment arrangement.

    Abstract: A releasable connection connects a first component to a second component. The second component includes and is manufactured from a Shape Memory Polymer (SMP), and defines a pocket. The first component includes a portion disposed within the pocket. The pocket is deformed from an initial shape permitting insertion of the portion into the pocket to assembly the releasable connection into a connected shape wherein the pocket is deformed to secure the first component relative to the second component. The pocket is transformed from the initial shape into the connected shape by heating the SMP material of the second component to a switching temperature. Re-heating the SMP second component to the switching temperature returns the pocket back to the initial shape from the connected shape to disassembly the releasable connection.
