  • Patent number: 6202498
    Abstract: An axial displacement arrangement in the form of a ball screw and nut achieves a highly compact configuration by effecting ball recirculation entirely within the ball screw shaft. The ball recirculation portion of the ball screw shaft is axially short with respect to an elongated driven nut. As the nut is rotated, illustratively by an electric motor coupled thereto, the ball screw shaft is displaced axially along an axial support member. The axial support member has radially outward extending splines, and the ball recirculation portion of the ball screw shaft has radially inward extending splines, the inward and outward splines being arranged to face one another whereby a linear ball bearing region is formed. The linear ball bearing permits the ball recirculation arrangement and its associated actuation element to be displaced axially along the support element, but is precluded from rotating.

  • Patent number: 6170326
    Abstract: Processes and apparatus for signal analysis enable “pass/fail” determinations to be made with respect to noisiness of a mechanical or electrical system under test, particularly the presence of bumps and nicks in gear train systems under test. In a process aspect, for a gear system, a torque input is applied. A first signal responsive to the torque applied to the gear system under test is produced, which is converted to digital data responsive to a first correlation between the first signal and time. Peaks in the digital data are measured to determine whether they exceed a predetermined threshold magnitude. The peaks that exceed the predetermined threshold magnitude are subjected to harmonic analysis, the results being compared to gear tooth harmonics to determine whether the peaks constitute an anomaly. Such an anomaly is a bump or a nick on a tooth of the gear system under test.

  • Patent number: 6126946
    Abstract: A heat and shelf-stable oil-in-water emulsion useful as a tissue or cell-selective delivery vehicle. Radioactive or stable, synthetic or semi-synthetic polyhalogenated triglycerides, such as 2-oleoylglycerol-1,3-bis[7-(3-amino-2,4,6-triiodophenyl)heptanoate] or 2-oleoylglycerol-1,3-bis[.omega.-(3,5-bis-trifluoromethyl)hepatanoate] or phenyl acetate, can be incorporated into the lipophilic core of a lipoprotein-like emulsion particle. The lipophilic core is surrounded by a phospholipid membrane comprising cholesterol and apolipoproteins. For hepatocyte-selective delivery, the emulsion is chylomicron remnant-like by being in a size range of 50 to 200 nm as measured by number weighting analysis with a narrow size distribution (<2% greater than 300 nm) and having a composition simulating naturally-occurring chylomicron remnants. Use of cholesterol in the emulsion formula facilitates association of apolipoproteins, especially Apo E which are recognized by liver cells and necessary for binding and uptake.

  • Patent number: 6118383
    Abstract: A system for detecting the presence of rain droplets on a windshield employs a source of radiant energy, such as an LED, and a photodetector installed on the instrument panel of a vehicle. The LED and the photodiode are arranged with respect to one another such that light from the LED cannot reflect directly off the windshield onto the photodiode. Only when the light from the LED is back scattered by an environmental condition, such as the raindrops on the exterior of the windshield, the condensation of moisture on the interior of the windshield, or the presence of smoke in the cabin, will the photodiode receive the light from the LED. Each of these environmental conditions has a predeterminable characteristic signature that permits the processing of data to detect same.
