  • System, circuit and method for tuning a resonant circuit
    Patent number: 7190153
    Abstract: A circuit may be tuned to resonate at a driving frequency. The circuit includes a source that provides an output at a drive frequency and a resonant circuit having an input coupled to the source, an output, and first and second selectable resonant frequencies. The first resonant frequency is below the drive frequency and the second resonant frequency is above the drive frequency. A control coupled to the resonant circuit output selects the first and second resonant frequencies to cause the resonant circuit to provide an output at an apparent resonant frequency equal to the drive frequency.

  • lysophosphatidic acid acyltransferase homolog for alteration of polyunsaturated fatty acids and oil content in oleaginous organisms
    Patent number: 7189559
    Abstract: Lysophosphatidic acid acyltransferase (LPAAT) participates in the second step of oil biosynthesis and is expected to play a key role in altering the quantity of long-chain polyunsaturated fatty acids produced in oils of oleaginous organisms. The present application provides a nucleic acid fragment (identified as “LPAAT2”) isolated from Mortierella alpina encoding a LPAAT homolog that is suitable for use in the manufacture of oils enriched in omega fatty acids in oleaginous organisms. Most desirably, the substrate specificity of the instant LPAAT2 will be particularly useful to enable accumulation of long-chain PUFAs having chain lengths equal to or greater than C20 in oleaginous yeast, such as Yarrowia lipolytica.

  • Retaining wall block
    Patent number: 7185470
    Abstract: A block for use in constructing a retaining wall and comprising a body having a central cavity extending vertically there through and defining front, rear, and side walls. The side walls diverge rearwardly from the front of the block to the rear. Stabilizing wings extending outwardly at the rear of the side walls. Positioning wedges extend from the bottom surface and include flat forward surfaces for positioning the block with respect to the blocks in a lower tier of blocks. The flat forward surfaces of the positioning wedges are located nearer the front surface of the block than is the inner surface of the front wall, thereby enabling a retaining wall created from the blocks to have each successive higher tier offset from the adjacent lower tier by a set distance. The block of the present invention provides a stable block having a large coverage area at a low weight.

  • Robotic apparatus and method for mounting a valve stem on a wheel rim
    Patent number: 7185410
    Abstract: An apparatus and method for mounting a valve stem to the rim of an vehicle wheel includes engaging a valve stem with a robotic manipulator, moving the valve stem relative to the rim along a programmable path of travel, coaxially aligning the valve stem with the aperture in the rim, and inserting the valve stem through the aperture in the rim. Preferably, the aperture location in the rim is determined at a gauging station by a machine vision system. If necessary, a power-actuated nut runner is used to tighten a nut over the valve stem. Alternately, the gauging station can use a table which rotates the wheel about a central axis, and an optical sensor detects the location of the aperture. Optionally, a probe mounted on the gauging station can be extended into the aperture to confirm the aperture position and to reposition the rim slightly if required.
