  • Publication number: 20170171454
    Abstract: Systems and methods are disclosed for selecting and orienting a computing device mounted on a robotic stand for videoconferences. For example, a method for operating a robotic stand supporting a computing device is disclosed, which includes displaying, by a display of a remote device, a control interface depicting a physical location that includes a plurality of robotic stands with respective computing devices. The method further includes providing, responsive to a user of the remote device interacting with the control interface, a selection instruction selecting a region of the physical location for viewing with one of the plurality of robotic stands with respective computing devices, and generating, by the control interface, a positioning instruction based on the selected region of the physical location, the positioning instruction configured to orient the robotic stand including the computing device determined to be available to face the region of the physical location.

  • Publication number: 20150260333
    Abstract: A robotic stand and systems and methods for controlling the stand during a videoconference are provided. The robotic stand may support a computing device during a videoconference and may be remotely controllable. The robotic stand may include a base, a first member, a second member, and a remotely-controllable rotary actuator. The first member may be attached to the base and swivelable relative to the base about a pan axis. The second member may be attached to the first member and may be tiltable relative to the first member about a tilt axis. The rotary actuator may be associated with the first member and operative to swivel the first member about the pan axis. In response to receiving a signal containing a motion command, the robotic stand may autonomously move the computing device about at least one of the pan axis or the tilt axis.

  • Patent number: 8316526
    Abstract: The present invention provides electroactive polymers, transducers and devices that maintain pre-strain in one or more portions of an electroactive polymer. Electroactive polymers described herein may include a pre-strained portion and a stiffened portion configured to maintain pre-strain in the pre-strained portion. One fabrication technique applies pre-strain to a partially cured electroactive polymer. The partially cured polymer is then further cured to stiffen and maintain the pre-strain. In another fabrication technique, a support layer is coupled to the polymer that maintains pre-strain in a portion of an electroactive polymer. Another embodiment of the invention cures a polymer precursor to maintain pre-strain in an electroactive polymer.

  • 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.

  • Publication number: 20080022517
    Abstract: The invention describes rolled electroactive polymer devices. The invention also describes employment of these devices in a wide array of applications and methods for their fabrication. A rolled electroactive polymer device converts between electrical and mechanical energy; and includes a rolled electroactive polymer and at least two electrodes to provide the mechanical/electrical energy conversion. Prestrain is typically applied to the polymer. In one embodiment, a rolled electroactive polymer device employs a mechanism, such as a spring, that provides a force to prestrain the polymer. Since prestrain improves mechanical/electrical energy conversion for many electroactive polymers, the mechanism thus improves performance of the rolled electroactive polymer device.
