  • Infrared remote control receiver and system
    Publication number: 20050047794
    Abstract: The present invention provides an infrared remote control receiver with increased suppression of unwanted light, signals, or interference, specifically suppression of interference from plasma television displays and fluorescent light. The infrared remote control receiver may be used in remote control applications whereby it is connected between at least one remote control unit and at least one device or component that is intended to be operated. The receiver also contains status and infrared activity indicators, which indicate whether the individual components of the system are powered and whether the receiver is receiving an infrared signal. The receiver eliminates or reduces interference received by the receiver using a method of processing signals that changes the voltage reference level if the signal is determined to be noise and maintains the noise level at an established limit.

  • Feedback circuit and method of operating ballast resonant inverter
    Publication number: 20050046359
    Abstract: A ballast resonant inverter with a self-oscillating driver IC powers and dims a gas discharge lamp. A feedback circuit automatically adjusts IC oscillator frequency for safe and stable inverter operation above the resonant frequency following changes in the resonant load. The feedback signal is derived from resonant inverter output voltage, by attenuating, programmed phase shifting and injecting the resulting signal in a timing circuit of the IC. The feedback circuit includes an active inverter circuit or passive RC phase boosting networks coupled in series. Phase control of the feedback signal by variable RC networks is used in transient modes of ballast-lamp operations.

  • Static mixer with polymorphic structure
    Publication number: 20050047274
    Abstract: The static mixer has a polymorphic structure that can be used for mixing or homogenizing a fluid medium. The mixer has at least two sections arranged in a tube one after the other in the longitudinal direction. Baffles of the first section that are effective to promote mixing redistribute the medium to be mixed largely globally over the entire cross-section of the tube. Baffles of the second section that are effective to promote mixing effect largely local mixing in partial regions, which in each case contain only one part of the tube cross-section. The baffles of both sections have the same or approximately equally large hydraulic diameters.

  • Ultrasound therapeutic device
    Patent number: 6860852
    Abstract: The ultrasound therapeutic system of the present invention generally includes a generator unit, at least one transducer treatment head, and a programmable controller. The generator is in operable communication with the at least one transducer treatment head such that electric power outputted from the generator to the head is converted into acoustic power by the head. Re-programmable software at the controller generally controls all features and functions for the system. In particular, the controller calculates an initial optimal treatment dose, maintains effective acoustic power transmitted to the patient through the at least one treatment head, performs calibration procedures for the at least one treatment head, controls outputting for each supported treatment mode, and provides for various other features and functions.

  • Lithographic apparatus and device manufacturing method
    Publication number: 20050041233
    Abstract: A lithographic apparatus is presented in which vibrations induced by reaction forces exerted on a base frame BF by accelerations within the apparatus are eliminated without the need for complex positioning systems and several balance masses. This is achieved by using feed-forward control to apply a compensating force using actuators to the base frame, based on knowledge of the movements and accelerations of the substrate table and other parts within the apparatus.

  • Dual stage inflator for low melting gas generants
    Patent number: 6851374
    Abstract: A dual stage invention is designed to autoignite an autoignition material before a low temperature gas generant melts. Low temperature gas generants include a high nitrogen content organic fuel with ammonium nitrate as the oxidizer. The dual stage inflator has a first gas generant and a second gas generant that are ignited by separate igniters. The first gas generant and the second gas generant are insulated from the inflator housing to delay the heat transfer from the housing to the first gas generant and second gas generant during a bonfire test, which needs to be passed to receive Department of Transportation classification. The dual stage inflator also has an autoignition cartridge for disposing of the second gas generant by the first gas generant after the first gas generant burns for a predetermined amount of time.

  • Programmable gain amplifier with glitch minimization
    Publication number: 20050024144
    Abstract: A programable gain amplifier (PGA) has an amplifier and a variable resistor that is connected to the output of the amplifier. The variable resistor includes a resistor that is connected to a reference voltage and multiple parallel taps that tap off the resistor. A two-stage switch network having fine stage switches and coarse stage switches connects the resistor taps to an output node of the PGA. The taps and corresponding fine stage switches are arranged into two or more groups, where each group has n-number of fine stage switches and corresponding taps. One terminal of each fine stage switch is connected to the corresponding resistor tap, and the other terminal is connected to an output terminal for the corresponding group. The coarse stage switches select from among the groups of fine stage switches, and connect to the output of the PGA.

  • Apparatus and methods for determining velocity of oil in a flow stream
    Patent number: 6850317
    Abstract: Apparatus and methods for measuring oil flow velocity in a well are provided which utilize fluorescence quenching. A marker which quenches the natural fluorescence of crude oil is chosen and injected into the oil flow at a first location. At a second location, the oil flow is subjected to light at a wavelength which will cause oil to naturally fluoresce. The fluorescence signal is detected at the second location by a sensing probe. The time that it takes for the quenching marker to move from the first location to the second location is measured by sensing a decrease in fluorescence due to the quencher. Fluid velocity is determined by dividing the distance between the marker-ejection point and the optical probe position by the time it took the marker to move that distance.
