  • Patent number: 7070237
    Abstract: A universal headrest mounting collar which is engaged with the rods of a headrest on a vehicle seat back and supports a video monitor thereon for viewing by a passenger in a rear seat. The bracket can be secured at a fixed vertical position on the headrest rods and collar assemblies surrounding the rods are horizontally slidable in grooves formed in the base of the bracket assembly to accommodate different spacing between headrest rods by different vehicle manufacturers. The monitor mounting element is universally adjustable to modify the viewing angle of the monitor screen.

  • Patent number: 7061230
    Abstract: A circuit for measuring distances and which has at least two inputs (1, 2), at least one measuring coil (3), and at least one signal source, wherein at least two input signals (epos, eneg) are generated by means of the signal source, and the inputs (1, 2) are activatable by means of the input signals (epos, eneg). The input signals (epos, eneg) are applied, preferably preprocessed, to the inputs of the measuring coil (3). The circuit is designed for use where little space is available for the circuit, with the input signals (epos, eneg) being applied to a preferably timed SC network, which generates a measuring output signal that is dependent on temperature. A corresponding method is also described.

  • Patent number: 7026627
    Abstract: A portable survey instrument and methodology yield intensity of neutron radiation, intensity of gamma radiation, and a direction of impinging gamma radiation. The instrument uses a neutron detector surrounded by an essentially rectangular moderator with preferably four gamma ray detectors disposed symmetrically about the neutron detector and within the moderator. Material and dimensions of the moderator are selected so that the neutron measurement is equally sensitive to fast and thermal neutrons. The moderator also induces angular responses to the gamma ray detectors. Responses of the gamma ray detectors are combined to yield a parameter indicative of the angular position of a source. The survey instrument is portable and suited for hand held use.

  • Patent number: 6575887
    Abstract: A surgically implantable radioactive wrap is positioned around the wall of a body vessel, duct or passageway to maintain patency of these structures by mitigating overexuberant cellular proliferation. Such excessive cellular growth may occur as the result of a disease process or following a trauma or an intentional surgical or intravascular intervention. The device provides for delivery of ionizing radiation to a localized target tissue site. Integral design features provide for the shielding of non-targeted tissues and for the attachment of the device to the target tissue structure. A radiation attenuation element serves to absorb extraneous low-energy electrons incidentally emitted by the treatment source and provides for a more uniform radiation dose distribution through the full thickness of the target tissues. The wrap can be easily applied with minimal handling and with limited radiation exposure to operating personnel.
