Patent number: 7274110Abstract: The invention relates to a semiconductor component for mounting on a printed circuit board. The semiconductor component includes a housing that at least partially surrounds at least one flat semiconductor chip. Electrical contacts are assigned to the semiconductor chip and serve to establish an electrical connection to electrodes provided on a printed circuit board. The flat semiconductor chip has a mounting lateral surface that includes contact surfaces configured to make contact with the electrical contacts. A buffer layer is located between the housing and the chip, and surrounds the chip up to a supporting surface located on the mounting lateral surface.Type: GrantFiled: February 22, 2005Date of Patent: September 25, 2007Assignee: Infineon Technologies AGInventors: Thorsten Meyer, Harry Hedler

Patent number: 7274111Abstract: A method and apparatus for operating a combined-cycle power system is provided. The system is coupled to an electric power grid. The system includes at least one electric power generator, at least one steam turbine coupled to the generator, at least one combustion turbine coupled to the generator, and at least one steam source that is in flow communication with the steam turbine. The method includes operating the system at a first power output level with the steam turbine and the combustion turbine being synchronized to an operating frequency of the grid, so that the steam turbine, the combustion turbine, and the grid are operating at a frequency substantially similar to a standardized grid frequency value. The method also includes sensing a grid frequency deviation away from the standardized grid frequency value.Type: GrantFiled: December 9, 2005Date of Patent: September 25, 2007Assignee: General Electric CompanyInventors: Philip Lynn Andrew, John Edward Ford, Timothy Andrew Melsert

Patent number: 7274114Abstract: A tracking and control method and circuit for use in a power management unit integrated circuit (PMUIC) that enables multiple voltage regulator outputs to maintain a same voltage or a ratiometric relation to a reference voltage source. When the reference voltage source is powered down or falls below a prescribed level, the tracking power supplies are automatically switched to their internal bandgap reference voltage. Accordingly, outputs of the tracking power supplies are prevented from introducing large transient excursions that might result in malfunctions in the circuitry of the load such as latch-ups. Ratiometric tracking further provides coordinated preservation of logic interface levels, and reduces leakage current.Type: GrantFiled: November 15, 2004Date of Patent: September 25, 2007Assignee: National Semiconductor CorporationInventor: Kern W. Wong

Patent number: 7274116Abstract: A bypass control section (6) maintains a bypass switch (5) in the ON state during the period when a battery voltage (Vi) is higher than the output voltage (Vo) to an external load (L). Upon falling of the output voltage (Vo) at a desired voltage (ET), a converter control section (4) starts switching control at once, and a step-up chopper (3) promptly starts boost operation. The bypass control section (6) maintains the bypass switch (5) in the ON state from the start of the boost operation of the step-up chopper (3) until the match between the battery voltage (Vi) and the output voltage (Vo).Type: GrantFiled: August 2, 2004Date of Patent: September 25, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Manabu Inoue, Takuya Ishii, Keiji Akamatsu, Masaaki Kuranuki, Hiroki Akashi

Patent number: 7274117Abstract: A radio wall switch that uses radio signals to control a load through a load circuit is disclosed. The radio wall switch is also configured group or bind electronic devices to operate collectively by responding to the same radio control signals. Preferably, the radio wall switch and electronic devices are grouped or bound to reflect their location in a floor plan architecture. The radio wall switch includes a radio control board is configured to be removable and located outside of a wall receptacle while electrically coupled to the load circuit. The radio control board includes contact switches that are selectively depressed by a switch plate for manually controlling the load. The switch plate is flexible and can be deformed to simultaneously actuate multiple contact switches to place the radio wall switch in a program mode for grouping or binding the other electronic devices.Type: GrantFiled: April 4, 2005Date of Patent: September 25, 2007Assignee: The Watt Stopper, Inc.Inventors: Roar Viola, Betrand Debever, Roy Nishi, Loiua Weidman
