摘要： Ultrasound devices and systems are disclosed in which cooling of an active acoustic element of an ultrasound transducer is achieved via an electrically conductive member that extends beyond a proximal side of the active acoustic element to contact a heat exchanger. The electrically conductive member delivers electrical driving signals to the active acoustic element while conducting heat to the heat exchanger. A region of the proximal surface of the active acoustic element that is free from contact with the electrically conductive member may also absent from contact with a liquid or a solid, thereby facilitating reflection of ultrasound energy. The heat exchanger may include an electrically insulating fluid that contacts the electrically conductive member to remove the heat conducted through the electrically conductive member. The active acoustic element may be a multilayer lateral mode element, and the electrically conductive member may form an electrode of the lateral mode element.

摘要： A microelectromechanical-systems (MEMS) device includes a driven mass and has a natural stiffness or damping. An actuator applies force to the mass, movement of which is measured by a sensing capacitor. A control circuit operates the actuator per displacement or velocity of the driven mass, so that a characteristic stiffness or damping of the mechanical subsystem is different from the respective natural value. A method of transforming a MEMS device design includes determining an aim performance value of the design and a baseline performance uncertainty of the design, selecting candidate sets of parameter values, determining a candidate, first, and second performance value for each, scoring the candidates, and repeating until one of the candidates satisfies a termination criterion, so the transformed design using that candidate set has the aim performance value and the respective first and second performance values closer to each other than the baseline performance uncertainty.

摘要： A balanced multi-phase energy conversion apparatus configured to convert energy from a mechanical energy source into electrical energy is disclosed. The energy conversion apparatus may comprise a plurality of transducers. Each of the plurality of transducers comprises a dielectric elastomer module comprising at least one dielectric elastomer film layer disposed between at least first and second electrodes. A transmission coupling mechanism is coupled to the mechanical energy source and operatively attached to the plurality of transducers. The transmission coupling cyclically strains and relaxes the plurality of transducers in response to the mechanical energy acting on the transmission coupling mechanism. The transmission coupling mechanism comprises a work cycle. The plurality of transducers are at evenly distributed points in the work cycle such that a total passive strain energy is constant.

摘要： An actuator apparatus comprising a smart material device, a compensator, a movable supporting member, at least three mechanical webs, at least three actuating arms, and a second stage assembly is disclosed wherein the mechanical webs comprise a first resilient member attached to the compensator and a second resilient member attached to said movable supporting member. A piezoelectric or smart material device is affixed between the first mounting surface and the compensator. The actuating arms comprise a first actuating arm end attached to one mechanical web and a second actuating arm end attached to the second stage assembly. The second stage assembly comprises resilient strips having a first end attached to the actuating arm and a second end attached to a second stage attachment surface. Application of an electrical potential causes the smart material device to expand, thereby urging the movable supporting member away from the compensator and causing the first and second resilient members to flex. This in turn causes the actuating arms to move. The resilient strips urge the second stage attachment surface in a direction substantially parallel to the smart material device.
