摘要： Systems and methods for sensing temperatures of multiple functional blocks within a digital device and controlling the operation of these functional blocks in a manner that selectively reduces temperatures associated with some of the functional blocks, but not others. One embodiment comprises an integrated circuit having multiple functional blocks (such as processor cores) and a set of thermal sensors coupled to sense the temperatures of the functional blocks. The integrated circuit includes control circuitry configured to receive signals from the thermal sensors, detect thermal events in the functional blocks and to individually adjust operation of the functional blocks to reduce the temperatures causing the thermal events. In one embodiment, the control circuitry includes a detection/control circuit coupled to each of the functional blocks and a thermal management unit configured to evaluate detected thermal events and to determine actions to be taken in response to the thermal events.

摘要： A method for converting low temperature dissipated heat to other useful energy and apparatus therefor. Heat energy is transferred to a shape memory alloy using natural conduction of the heat. The kinetic energy of the shape memory alloy resulting from cyclic temperature variations is transferred to another type of energy such as electrical energy.

摘要： An apparatus and method for converting waste heat from a low temperature heat source, such as an electrical component, to work energy and for efficiently transferring unconverted or remaining waste heat away from the heat source. The apparatus includes a chamber having a first location adapted to receive heat from the heat source, and a second location adapted to dissipate heat transferred via an acoustic wave in the chamber. The acoustic wave may be produced by a first vibration member coupled to an interior surface of the chamber and disposed at an end of the chamber, where the first vibration member is adapted to vibrate at a resonant frequency of the chamber. Alternatively, a first and a second vibration member that are both adapted to vibrate at the resonant frequency of the chamber may be disposed equidistant from opposing ends of the chamber to produce a standing acoustic wave within the chamber. Each vibration member is coupled to a respective transducer that senses a deformation of the respective vibration member and generates a proportional AC voltage which may be stored in an electrical storage for supply to an external load.
