  • Patent number: 6843004
    Abstract: A backhoe (100) has a hydraulic cylinder (316, 317) with a piston (318, 319) that rotates a rotatable boom (108). A lockable slider block (322) slides on the piston. Movement of the lockable slider block in one direction is caused by a spring (328, 329) mounted around the piston, and in another direction is caused by the telescoping of the piston into the hydraulic cylinder. The backhoe includes a hydraulic valve (340) that controls hydraulic pressure to the hydraulic cylinder and a sensor (320) coupled to the hydraulic valve. Once locked to a position on the piston, the lockable slider block engages the sensor on each occasion the rotatable boom rotates beyond a preselected angle of rotation. Engagement of the sensor causes actuation of the hydraulic valve, thereby preventing further rotation of the boom by the hydraulic cylinder. Alternative embodiments have an encoder (120, 130) that digitizes the position of the boom, and a microcomputer (410) that is programmed to actuate the hydraulic valve.

  • Patent number: 6696900
    Abstract: The present invention is a method for demodulating a PSK modulated signal wherein the PSK system incorporates a transmitter generating a PSK modulated signal and wherein the transmitter is crystal based. A crystal based receiver receives the PSK modulated signal and the delta phase between the recovered PSK signal and a receiver generated reference signal is measured; the measurement is repeated with a predetermined phase shift. Voltage values are derived representing the results of each of the measurements and are applied to an analog-to-digital converter to derive digital values representing the two phases measured, and a corresponding delta phase. The digital values are applied to a look up table to derive a phase correction for the reference signal, and several methods are described to perform various types of PSK demodulation.

  • Patent number: 6607583
    Abstract: A method and apparatus for controlling the heating of adsorbent materials in a vessel including the utilization of electrodes in direct contact with the adsorbent material to induce a current in the material. The electrical contacts are spaced apart and receive a potential for inducing the electrical current; one of the electrodes is a different size to thereby induce a radial component in the electrical current to thus modify the current density flowing through the adsorbent material as the current traverses the distance between the electrodes. The resulting modified current density causes the temperature gradient across the transverse section of the vessel to decrease, thus rendering the temperature more uniform across the vessel.

  • Patent number: 6529049
    Abstract: A buffered sample-and-hold circuit includes two sampling capacitors for each analog voltage to be sampled. The two sampling capacitors are initially charged simultaneously to the analog voltage to be sampled. One of such sampling capacitors is thereafter temporarily coupled to the input terminal of a unity gain amplifier to pre-charge such input terminal, and any associated parasitic capacitance, to a voltage very near the actual sampled analog voltage. Following such pre-charge operation, that sampling capacitor is de-coupled from the input terminal of the amplifier; the other sampling capacitor is then coupled to the input terminal of the amplifier for establishing the actual sampled voltage at the input terminal of the amplifier.

  • Patent number: 6445069
    Abstract: A nickel/palladium/gold metallization stack is formed upon connection pads of integrated circuits at the wafer level through an electroless plating method. The metallization stack can be formed over copper or aluminum interconnect pads; the lower nickel layer bonds securely to the copper or aluminum interconnect pads, while the intermediate palladium layer serves as a diffusion barrier for preventing the nickel from out-diffusing during subsequent thermal cycles. The upper gold layer adheres to the palladium and readily receives a variety of interconnect elements, including gold bumps, gold wire bonds, solder bumps, and nickel bumps. The electroless plating process permits connection pads to be formed using fine geometries, and allows adjacent connection pads to be formed within 5 micrometers of each other.
