摘要： A shape memory alloy (SMA) heat engine includes a first rotatable pulley, a second rotatable pulley, and an SMA material disposed about the first and second rotatable pulleys and between a hot region and a cold region. A method of starting and operating the SMA heat engine includes detecting a thermal energy gradient between the hot region and the cold region using a controller, decoupling an electrical generator from one of the first and second rotatable pulleys, monitoring a speed of the SMA material about the first and second rotatable pulleys, and re-engaging the driven component if the monitored speed of the SMA material exceeds a threshold. The SMA material may selectively change crystallographic phase between martensite and austenite and between the hot region and the cold region to convert the thermal gradient into mechanical energy.

摘要： An energy harvesting system for converting thermal energy to mechanical energy includes a heat engine that operates using a shape memory alloy active material. The shape memory alloy member may be in thermal communication with a hot region at a first temperature and a cold region at a second temperature lower than the first temperature. The shape memory alloy material may be configured to selectively change crystallographic phase between martensite to austenite and thereby one of contract and expand in response to the first and second temperatures. A driven component, such as an electric generator, may be selectively coupled with the heat engine through a coupling device, which may be controlled via a controller.

摘要： A heat engine includes a first rotatable pulley and a second rotatable pulley spaced from the first rotatable pulley. A shape memory alloy (SMA) element is disposed about respective portions of the pulleys at an SMA pulley ratio. The SMA element includes a first wire, a second wire, and a matrix joining the first wire and the second wire. The first wire and the second wire are in contact with the pulleys, but the matrix is not in contact with the pulleys. A timing cable is disposed about respective portions of the pulleys at a timing pulley ratio, which is different than the SMA pulley ratio. The SMA element converts a thermal energy gradient between the hot region and the cold region into mechanical energy.

摘要： Accessing interior compartments for storage or other purposes is improved by the use of one or more active material components. Activating one or more active material components carries out one or more of the following functions: opening or closing the compartment (which may include cinching a closure) and/or latching or unlatching a closure from a frame. Activation may result from a remote trigger signal. A method is provided for controlling access to an interior compartment that may be carried out by a controller operatively connected to various active material components that unlatch the closure from the frame, close the closure and cinch the closure to the frame, respectively.

摘要： An energy harvesting system comprises a first region having a first temperature and a second region having a second temperature. A conduit is located at least partially within the first region. A heat engine configured for converting thermal energy to mechanical energy includes a shape memory alloy forming at least one generally continuous loop. The shape memory alloy is disposed in heat exchange contact with the first region and the second region. A carrier surrounds the conduit such that the carrier is driven to rotate around the conduit by the shape memory alloy in response to the temperature difference between the first region and the second region.
