  • Publication number: 20180323044
    Abstract: A plasma chamber is provided to increase conductance within the plasma chamber and to increase uniformity of the conductance. A radio frequency (RF) path for supplying power to the plasma chamber is symmetric with respect to a center axis of the plasma chamber. Moreover, pumps used to remove materials from the plasma chamber are located symmetric with respect to the center axis. The symmetric arrangements of the RF paths and the pumps facilitate an increase in conductance uniformity within the plasma chamber.

  • Patent number: 8800366
    Abstract: This invention relates to a robotic exoskeleton comprising mechanical linkages that couple to one or more selected joints of a limb of a subject. The robotic exoskeleton may be provided with means for obtaining data respecting angular position, torque, and/or acceleration of at least one of the joints or the links of the mechanical linkages, and may be used for assessing, studying, diagnosing a deficit, and/or treating an impairment in sensorimotor function of a limb of a subject.

  • Patent number: 8730266
    Abstract: This invention relates to gaze tracking methods and systems integrated with virtual reality (VR) or augmented reality (AR). A system may include one or more cameras for capturing images of a subject's eyes, a display device for displaying a VR or AR image, a first reflecting surface associated with the display device for at least partially reflecting light from the eyes to the one or more cameras and for transmitting the VR or AR image; and a second reflecting surface for at least partially reflecting light from the eyes to the one or more cameras and for receiving the VR or AR image and rendering the VR or AR image to the subject as at least one component of a VR or AR environment. The methods and systems described herein may be used in research, medical, industrial, aerospace, and entertainment applications.

  • Patent number: 8277396
    Abstract: This invention relates to a method and apparatus for assessing proprioception in a subject. One embodiment of an apparatus of the invention comprises two articulating members attachable to a pair of limbs of a subject, and provides data relating to geometry and/or location and/or motion of each limb in 2- or 3-dimensional space. The apparatus may include means for monitoring gaze direction. The apparatus may comprise a robotic linkage. One embodiment of the method comprises obtaining data relating to the geometry and/or location and/or motion of the limbs, or portions thereof, of a subject as the subject performs a matching task. Another embodiment comprises obtaining data relating to the location of a limb of a subject, together with data relating to gaze direction as the subject looks toward the perceived location of limb.

  • Patent number: 5048445
    Abstract: A fluid jet system for underwater maintenance of a ship hull is provided. The fluid jet system includes an open frame cart having a high pressure fluid nozzle manifold for cleaning and smoothing the submerged hull of the ship. One or more thruster assemblies are provided on the cart for deploying the cart through the water, advancing the cart along the hull and maintaining the cart in contact with the hull. Control of the thruster assembly and fluid flow manifold can be effected from either longitudinal end of the cart. Flexible fluid flow lines interconnect the cart to one or more remote sources of pressurized fluid so that the cart is independently operable. A system for deploying the cart is further provided and includes the necessary high pressure pumps, devices for hose deployment and retrieval, and diver supplies.
