  • Patent number: 8106701
    Abstract: A level shifter circuit suitable for high voltage applications with shoot-through current isolation is presented. The level shifter receives a first enable signal and receives an input voltage at a first node and supplies an output voltage at a second node. The circuit provides the output voltage from the input voltage in response to the first enable signal being asserted and sets the output node to a low voltage value when the first enable signal is de-asserted. The level shifting circuit includes a depletion type NMOS transistor, having a gate connected to the output node, and a PMOS transistor, having a gate connected to the first enable signal. It also includes a first resistive element that is distinct from the NMOS and PMOS transistors. The NMOS transistor, the PMOS transistor and the first resistive elements are connected in series between the first and second nodes, with the NMOS transistor being connected to the first node.

  • Patent number: 8090603
    Abstract: A system is provided that enables customers to search for event tickets for purchase. A computer interacts with the user to allow the user to specify criteria for event tickets the user wishes to purchase. The system presents relevant event ticket results, and provides filters for the user to further refine those search results. The user selects an event, and then selects tickets for that event. Ticket availability is shown, with seat locations indicated directly on an interactive venue map. For purchase, the user is directed to the selling ticket provider.

  • Publication number: 20110296918
    Abstract: The miniaturized piezoelectric accelerometer includes a support frame (102) having a cavity (104) and a seismic mass (108) supported by a plurality of suspension beams (110) extending from the support frame (102). Each of the suspension beams (110) has a piezoelectric thin film coated on a top surface thereof, with a pair of inter-digital electrodes (114) deposited on an upper surface of each piezoelectric thin film. The presence of acceleration excites bending and thus strain in the piezoelectric thin film, which in turn causes electrical signals to be generated over terminals of the electrodes (114). To collect constructively the output of the electrodes (114), one terminal of each of the electrodes (114) is routed to and electrically connected at a top surface (308) of the seismic mass (108).

  • Publication number: 20110302523
    Abstract: This disclosure describes a system in which individual employee records can be updated across multiple services by an administrator at the interface to a particular service. Multiple services may be provided with this capability. This will eliminate the need in the current art for a central directory that contains a service description that will be common across all services. The technology eliminates the need for the development of this directory and the training of administrators in its interface. Administrators may utilize their training in one service interface to update records across multiple services. This will enable the more rapid development of solutions utilizing services from multiple vendors. Administrators need not be trained on interfaces for all services but can apply routine global updates from a convenient and familiar interface.
