  • Patent number: 9563274
    Abstract: The present invention relates to an adaptable input/output device. One embodiment of a hardware device for facilitating an interaction between a computing system and a user includes: an interaction surface for supporting the interaction, a single actuator capable of driving a first region of the interaction surface, and a first selective clamping mechanism capable of restricting movement of one or more second regions of the interaction surface that partly intersect the first region, wherein a displacement of one or more desired portions of the interaction surface is dynamically controllable.

  • Publication number: 20120313854
    Abstract: The present invention relates to an adaptable input/output device. One embodiment of a hardware device for facilitating an interaction between a computing system and a user, the hardware device includes an adaptable surface for supporting the interaction, where the adaptable surface is dynamically deformable under a control of the computing system, and one or more sensors, in communication with the computing system, for detecting a physical presence that is not in direct contact with the adaptable surface. The computing system is configured to cause a deformation of the adaptable surface in response to the physical presence.

  • Patent number: 7971850
    Abstract: The invention describes devices for controlling fluid flow, such as valves. The devices may include one or more electroactive polymer transducers with an electroactive polymer that deflects in response to an application of an electric field. The electroactive polymer may be in contact with a fluid where the deflection of the electroactive polymer may be used to change a characteristic of the fluid. Some of the characteristic of the fluid that may be changed include but are not limited to 1) a flow rate, 2) a flow direction, 3) a flow vorticity, 4) a flow momentum, 5) a flow mixing rate, 6) a flow turbulence rate, 7) a flow energy, 8) a flow thermodynamic property. The electroactive polymer may be a portion of a surface of a structure that is immersed in an external fluid flow, such as the surface of an airplane wing or the electroactive polymer may be a portion of a surface of a structure used in an internal flow, such as a bounding surface of a fluid conduit.

  • Patent number: 7898159
    Abstract: Described herein are compliant electroactive polymer transducers for use in acoustic applications. A compliant electroactive polymer transducer includes a compliant electroactive polymer at least two electrodes. For sound production, circuitry in electrical communication with the transducer electrodes is configured to apply a driving signal that causes the electroactive polymer to deflect in the acoustic range.

  • Patent number: 6734436
    Abstract: The invention relates to microfluidic devices and methods that employ electromagnetic radiation to move a droplet of fluid on a fluid-transporting surface of a substrate. Typically, radiation of a particular wavelength is directed through a substantially transparent material, and the radiation imparts an optical trapping force to move the droplet. In addition, a means for reducing evaporative loss from the droplet may be provided.
