    摘要： An exhaust system configured for converting thermal energy to mechanical energy includes a source of thermal energy provided by a temperature difference between an exhaust gas having a first temperature and a heat sink having a second temperature that is lower than the first temperature. The exhaust system also includes a conduit configured for conveying the exhaust gas, a heat engine disposed in thermal relationship with the conduit and configured for converting thermal energy to mechanical energy, and a member disposed in contact with the conduit and configured for conducting thermal energy from the conduit to the heat engine. The heat engine includes a first element formed from a first shape memory alloy having a crystallographic phase changeable between austenite and martensite at a first transformation temperature in response to the temperature difference between the exhaust gas and the heat sink.

    摘要： An energy harvesting system includes a heat engine and a component configured to be driven by operation of the heat engine. The heat engine includes a first member, a second member, a shape memory alloy material, and a tensioner. The second member is spaced from the first member. The shape memory alloy material operatively interconnects the first member and the second member. The shape memory alloy material is configured to selectively change crystallographic phase from martensite to austenite and thereby contract in response to exposure to a first temperature. The shape memory alloy material is also configured to selectively change crystallographic phase from austenite to martensite and thereby expand in response to exposure to a second temperature. The tensioner is configured to apply tension to the shape memory alloy material as the shape memory alloy material selectively expands and contracts such that the shape memory alloy material is taut.

    摘要： A mechanical system selectively imparts a prescribed motion to an output load using two or more actuators, including at least one having an active material element. The output load can be a locking member when the system is a vehicle transmission, a shuttle car of a linear system, or another device. A controller determines a total motive force required for imparting the prescribed motion, and selectively commands a combination of the actuators to provide the total motive force, apportioning the total motive force between the various actuators to optimize the performance of the system. An algorithm determines which combination of the actuators is the most suitable in moving the output load, and continuously modified this combination as needed as the output load is moved. The other actuator or actuators are then selectively energized as needed to provide the total motive force depending on this suitability determination.

    摘要： Remotely engageable and releasable suction cups include a pliable body and an active material in operative communication with the pliable body and configured to create and/or eliminate a partial vacuum through the activation of stiffness or geometry changes in the active material. Suitable active materials include shape memory materials such as shape memory alloys, ferromagnetic shape memory alloys, and shape memory polymers (SMP). A second class of active materials include materials that exhibit a change in at least one attribute when subjected to an applied field but revert back to their original state upon removal of the applied field. Active materials in this category include piezoelectric materials, electroactive polymers (EAP), magnetorheological polymers, and the like.
