  • Patent number: 8892461
    Abstract: Methods, systems and apparatuses for authenticating a user of a mobile device are disclosed. One method includes tracking a plurality of locations of the mobile device, tracking motion behavior of the mobile device, and generating a user profile for the user over a period of time based on the tracked plurality of locations and the tracked motion behavior. A present user of the mobile device is authenticated based on a comparison of the user profile with a present user profile of the present user, wherein the present user profile comprises recent location information of the mobile device and recent motion behavior of the mobile device.
    Type: Grant

  • Patent number: 7371285
    Abstract: A semiconductor processing chamber having a motorized lid is provided. In one embodiment, the semiconductor processing chamber generally includes a chamber body having sidewalls and a bottom defining an interior volume. A lid assembly is coupled to the chamber body and is movable between a first position that encloses the interior volume and a second position. A hinge assembly thereto is coupled between the lid assembly and the chamber body. A motor is coupled to the hinge assembly to facilitate moving the lid assembly between the first position and the second position.

  • Patent number: 6736668
    Abstract: An electrical coupler comprises an inner connector having upper and lower ends, an insulative outer connector element circumscribing the inner connector, and a thermally conductive flange disposed over the upper end of the inner connector and the outer connector for conducting heat from the electrical conductor. The electrical conductor may be utilized in a substrate support for semiconductor wafer processing. The substrate support comprises a chuck body having an electrode embedded therein, and an upper male connector coupled to the electrode and protruding from said chuck body. A cooling plate having the electrical coupler is positioned proximate to the chuck body. The upper male connector is inserted in the electrical coupler, and a power source coupled to the lower portion of the electrical coupler chucks and biases a wafer to an upper surface of said chuck. The thermally conductive flange conducts and transfers heat generated from the upper male connector and electrical coupler to the cooling plate.
