  • Patent number: 8920241
    Abstract: A computing system translates a world space position of a hand of a human target to a screen space position of a user interface and locks the hand to a handle of the user interface if world space parameters of the hand overcome a grab threshold of the handle. When the hand is locked to the handle, the computing system translates a world space position of the hand to a screen space handle position that is constrained along one or more interface guides. The hand is unlocked from the handle at a release position of the handle if world space parameters of the hand overcome a release threshold of the handle. The handle is retained at the release position after the hand is unlocked from the handle.

  • Publication number: 20070187089
    Abstract: A system for heating at least a part of a subsurface hydro carbonaceous earth formation forms a borehole into or adjacent to the formation, places elongated coaxial inner and outer conductors into the borehole with the inner and outer conductors electrically connected to each other at a depth below the top of the formation, and connects an AC power source to at least the outer conductor to produce heat in at least one of the conductors. The AC output has a controlled frequency, and the outer conductor comprises a standard oil well component made of a ferromagnetic material that conducts current from the AC power source in only a surface region of the conductor due to the skin effect phenomenon. More heat is dissipated from portions of the conductor that is within the depth range of the formation than from other portions of the conductor.

  • Patent number: 4144935
    Abstract: The disclosure describes a technique for uniform heating of relatively large blocks of hydrocarbonaceous formations in situ using radio frequency (RF) electrical energy that is substantially confined to the volume to be heated and effects of dielectric heating of the formations. An important aspect of the disclosure relates to the fact that certain hydrocarbonaceous earth formations, for example raw unheated oil shale, exhibit dielectric absorption characteristics in the radio frequency range. In accordance with the system of the invention, a plurality of conductors are inserted in the formations and bound a particular volume of the formations. The phrase "bounding a particular volume" is intended to mean that the volume is enclosed on at least two sides thereof. Electrical excitation is provided for establishing alternating electric fields in the volume.
