    Abstract: 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.

    Abstract: An accessory drive system for a motor vehicle is provided including first and second gear sets having first, second, and third members configured to selectively connect vehicle accessories to an engine and motor/generator. The first member of each gear set is continuously interconnected to the other. The second member of each gear set is continuously interconnected to the other. The motor/generator is configured to drive the accessories at a selectable rate independent of engine speed. A first torque transmitting device is operatively connected to the gear sets to allow the motor/generator to re-start the engine and power the accessories while restarting the engine. A second torque transmitting device is operatively connected to the engine's output shaft to allow the motor/generator to power the accessories while the vehicle is off.

    Abstract: An energy harvesting system comprises a first region having a first temperature and a second region having a second temperature. A heat engine is configured for converting thermal energy to mechanical energy. The heat engine includes a plurality of discrete elements of a shape memory alloy each having a crystallographic phase changeable between austenite and martensite in response to a temperature difference between the first region and the second region. At least one member of the heat engine is driven to rotate about a first axis by the phase change of the plurality of discrete elements.

    Abstract: A method of controlling an energy harvesting system that converts excess thermal energy into mechanical energy and includes a Shape Memory Alloy (SMA) member, includes obtaining current operational parameters of the energy harvesting system, such as a maximum temperature, a minimum temperature and a cycle frequency of the SMA member. The current operational parameters are compared to a target operating condition of the energy harvesting system to determine if the current operational parameters are within a pre-defined range of the target operating condition. If the current operational parameters are not within the pre-defined range of the target operating condition, then a heat transfer rate to, a heat transfer rate from or a cycle frequency of the SMA member is adjusted to maintain operation of the energy harvesting system within the pre-defined range of the target operating condition to maximize efficiency of the energy harvesting system.

    Abstract: The present invention provides an accessory drive system for a hybrid vehicle. The accessory drive system includes a planetary gear set having a first, second, and third planetary member. A torque transfer device operatively connects an engine with the first planetary member. A motor/generator is operatively connected to the second planetary member, and a plurality of accessories are operatively connected to the third planetary member. A one-way clutch is preferably operatively connected to either the first planetary member or the torque transfer device such that the accessories can be effectively driven by the motor/generator when the engine is off. Engine output is transferable through the planetary gear set to drive the accessories, and the speed at which the accessories are driven is selectable by controlling the speed of the motor/generator.
