Patent number: 7244078Abstract: A control gate is adapted to be installed across a channel for liquids. The Control gate has a barrier member capable of vertical or tilting movement and it is either slidingly or pivotally mounted to a frame of the control gate. In one instance, the control gate has at least one side member attached to the barrier member. A drive member co-operates with the side member(s) to allow raising and lowering of the barrier member to regulate flow of liquid through the control gate. The drive member includes a spool and an engagement member that is secured under tension and winds around the spool. As the spool turns it causes, with the engagement member, movement of the barrier member. Also described is a method of measuring flow rate through a control gate.Type: GrantFiled: September 27, 2005Date of Patent: July 17, 2007Assignee: Rubicon Research Pty, Ltd.Inventors: David Aughton, Iven Mareels, Erik Weyer

Patent number: 7245222Abstract: A method and apparatus for controlling a radio frequency identification (RFID) reader to detect the proximity of an RFID device based on observing a change in effective inductance. The RFID reader includes an excitation signal generator and a resonant filter that combined are capable of generating and transmitting a detection signal, an RFID device detector for measuring a detector parameter indicative of the change in effective inductance, and a detection signal receiver for determining whether an RFID device is present. The method includes awakening from a detection sleep state at a preselected time, generating and transmitting a detection signal, measuring at least one detector parameter indicative of the change in effective inductance, and determining whether the RFID device is present. When the RFID device is not present, the method returns to the detection sleep state and, when the RFID device is present, the method exits the detection sleep state.Type: GrantFiled: January 14, 2005Date of Patent: July 17, 2007Assignee: Farpointe Data, Inc.Inventor: Kirk B.

Patent number: 7242725Abstract: An adaptive broadband post-distortion receiver for wireless digital communications improves performance of a wireless digital communications system. The improved performance of the system includes improved linear AM-AM and AM-PM responses approaching saturation. Indeed, the proposed adaptive broadband post-distortion receiver has an effect on attributes such as bit error rate and transmitter power efficiency and, in turn, on modulation and bandwidth. The adaptive broadband post-distortion receiver is configured with an adaptively controlled IF post-distorter located at the IF stage of the receiver. The placement of the distortion canceling function in the IF section of the receiver lends itself to broadband applications. The post-distorter is configured to cancels the distortion produced by the transmitter and receiver as it is adaptively controlled using bit error rate calculations. The distortion canceling utilizes bit error rate information that is otherwise available in the receiver.Type: GrantFiled: April 2, 2003Date of Patent: July 10, 2007Assignee: Harris Stratex Networks Operating CorporationInventors: Frank S. Matsumoto, David C. M. Pham

Patent number: 7242614Abstract: Rewriteable electronic fuses include latches and/or logic gates coupled to one or more nonvolatile memory elements. The nonvolatile memory elements are configured to be programmed to memory values capable of causing associated electronic circuits to settle to predetermined states as power-up or reset signals are applied to the fuses. Although not required, the nonvolatile memory elements used in the rewriteable electronic fuses may comprise floating-gate transistors. An amount of charge stored on the floating gate of a given floating-gate transistor determines the memory value and, consequently, the state to which a fuse settles upon power-up or reset of the fuse.Type: GrantFiled: March 30, 2004Date of Patent: July 10, 2007Assignee: IMPINJ, Inc.Inventors: Christopher J. Diorio, Frédéric J. Bernard, Todd E. Humes, Alberto Pesavento

Patent number: 7239678Abstract: A control word generator comprised of circuitry to generate a control word to control an attenuator. The control word generator includes a counter that increments at a clock rate much higher than the refresh rate at which the error signal is recalculated. The counter is controlled by a comparator which compares the error signal to a reference value, which, starting from a programmable upper limited is decremented in the counter's incrementation rate by a programmable step size. When the reference value equals the error signal, the comparator changes state and the counter stops incrementing. The count at that time is the control word, which if everything operated instantaneously, would be the control word that would alter the attenuation sufficiently to achieve nominal power.Type: GrantFiled: January 19, 2006Date of Patent: July 3, 2007Assignee: Terayon Communications Systems, Inc.Inventor: Syed Habib Rahman

Patent number: 7236351Abstract: The high-voltage metal-clad substation element comprises at least one circuit-breaker connected electrically and mechanically to at least one set of busbars (3, 4) extending along an axis (D) that extends transversely to the longitudinal axis (AX) of the circuit-breaker. The metal case (1) is fixed to the ground via a hinge which allows the case to tilt slightly when said set of busbars (3, 4) expands along said transverse axis (D). This configuration makes it possible to omit or to reduce the use of axial bellows on the set of busbars, thereby reducing the cost of manufacturing the metal-clad substation. Advantageously, in association with the hinge, the metal case is designed to have some flexibility to reduce mechanical stresses when the set of busbars expands.Type: GrantFiled: December 20, 2002Date of Patent: June 26, 2007Assignee: Areva T & D SAInventors: Michel Chavot, Alain Arnaud

Patent number: 7236745Abstract: A detector module is described wherein the detector module includes a housing with a conductive waveguide, a detector, a temperature sensor, and detector circuitry. The waveguide is made of a conductive material and of an appropriate size for a signal of a particular frequency. The detector, which can be a detector diode, protrudes a distance into the waveguide so as to produce a detector signal. The temperature sensor generates a temperature signal responsive to a temperature. The detector circuitry is contained within the housing. Moreover, the detector circuitry is configured to receive and condition the detector signal into a detector module signal. The detector module signal and temperature signal are then associated with a previously calibrated power level. With calibrated power level information, an input signal to a transmitter can be attenuated or amplified to control its output power.Type: GrantFiled: March 5, 2003Date of Patent: June 26, 2007Assignee: Harris Stratex Networks Operating CorporationInventors: Jonathan Andrew Wells, Louis Arthur Salinas, Paul Alan Kennard
