    摘要: An energy harvesting system comprises a first region and a second region having a temperature difference therebetween. A heat engine is configured for converting thermal energy to mechanical energy. The heat engine includes a first discrete element of a shape memory alloy having a crystallographic phase changeable between austenite and martensite in response to the temperature difference between the first region and the second region. The first discrete element of the shape memory alloy expands and contracts in response to the phase change to exert a linear force. A motion conversion mechanism is operatively connected to the first discrete element to be driven by the linear force and a component is driven by the motion conversion mechanism.

    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.
