  • Patent number: 6535832
    Abstract: A vehicle exhaust system test fixture integrates separate dynamic controls to provide at least twelve degrees of freedom (DOF). In one embodiment, two separate test tables are integrated so that one of the tables supports mounting of an engine/powertrain or apparatus simulating the engine/powertrain when coupled to an exhaust system. The other table supports mounting of the exhaust system to be tested. Each table is linked to a set of actuators/accelerometers to control motion up to 6 DOF. The capability of twelve DOF allows the test fixture to accurately reproduce both the dynamic behavior of a vehicle engine/powertrain during operation, and the dynamic behavior of the vehicle chassis during operation in the area where the exhaust system is attached to the vehicle frame. In addition, generated thermal profiles and high frequency external vibrations can be applied to allow simulation of real-world vibrations, and thermal stresses caused by hot exhaust gases.

  • Publication number: 20020024500
    Abstract: A wireless control device includes a small, lightweight housing worn by an operator, for example on the operator's wrist, and a controlled device, for example a personal computer. Several optical emitters, preferably light emitting diodes operating in the infrared range, and several optical detectors are provided on the housing. At least one x-axis emitter-detector pair operates to detect an x-direction of a pointing motion or gesture, and at least one y-axis emitter-detector pair operates to detect a y-direction of a pointing motion or gesture. This motion can then be used to cause a response in the controlled device. For example, angles of the operator's hand at the wrist can be interpreted to induce motion of a cursor on a computer display. The device may also include a motion sensor, an environmental condition sensor, or a voice recognition sensor, and can also be adapted for gesture recognition and image scanning applications.

  • Patent number: 6190715
    Abstract: A method for producing edible quality refined fish oil comprising the steps of extracting press liquor from a cooked fish, wherein the press liquor consists primarily of fish oil and water inherent in the cooked fish. The fish oil is from the group of fish consisting of menhaden, other similar fish, and mixtures thereof. Enzymes present in the press liquor are deactivated by injecting an acidic solution into said press liquor. After the fish oil is removed from the press liquor, the fish oil is cold filtered to produce an olein fraction and a stearine fraction. The stearine fraction is separated from the olein fraction and fatty acids that remain in the olein fraction are removed. Then bleaching the fish oil by mixing amorphous silica and diatomaceous earth with the fish oil, under vacuum conditions, and deodorizing the fish oil under vacuum conditions with steam injection. Finally, preparing the fish oil for storage by mixing a chelating agent and anti-oxidants with fish oil.

  • Patent number: 5793797
    Abstract: An electronic data transmission system has a low peak-to-average power ratio by including a transmitter circuit which receives an input signal and in response generates a distorted output signal. This distorted output signal is generated by amplifying the input signal with one particular gain when the input signal is at a maximum magnitude which gives the distorted output signal a corresponding maximum magnitude, and by amplifying the input signal with a larger gain when the input signal is in a predetermined range below the maximum magnitude. The distorted output signal travels over a communication channel to a receiver circuit, which regenerates the input signal by amplifying the distorted output signal with a gain that is the inverse of the gain by which the distorted signal is generated.

  • Patent number: 5696795
    Abstract: An improved quadrature phase shift key modulator circuit of the type which includes a non-linear amplifier in the transmitter and includes a frequency select logic circuit for receiving the in phase and quadrature phase digital data to be modulated onto a carrier frequency signal. The output of the frequency select circuit produces select signals that are coupled to the input of a digital carrier frequency generator. The digital carrier frequency generator synthesizes and increases, decreases, or leaves unchanged the carrier frequency as a representation of the data occurring on the in phase and quadrature phase input lines. The output of the digital carrier frequency generator is smoothed and converted to an analog signal which has a constant vector power magnitude during phase change.

  • Patent number: 4688327
    Abstract: Apparatus for processing the damaged tubes of a steam generator. This apparatus includes a sleeving tool for inserting sleeves in the tubes, a high-roller tool for rolling the sleeves at their upper ends where they have been expanded, and a low-roller tool for rolling the sleeves at their lower ends in the tube sheet. Each tool is provided with locking pins which engage tubes adjacent to a tube to be processed and suspend the tool in processing position. The sleeves are inserted in the tubes and are rolled by rolls driven by a hydraulic motor. For sleeve insertion and for high and low rolling, the motor is controlled by a servo control valve. The feedback signal to this valve is derived from a flow transducer in the feed line for the motor. The feedback for the force of sleeve insertion is the pressure across the motor derived from pressure transducers in the conductors through which the motor is supplied. For insertion speed and for rolling speed, the feedback is derived from a fluid-flow transducer.
