Abstract: A method and apparatus for measuring the amount of flow of a flowing medium. The method and apparatus include a bridge circuit configured to develop a bridge voltage Vb such that the magnitude of the bridge voltage Vb is indicative of the amount of flow. The bridge circuit is configured without having an ambient temperature sensor, thus the bridge voltage is uncompensated with respect to ambient temperature. A thermistor circuit is configured to generate a temperature reference voltage indicative of ambient temperature. A conditioning circuit is configured to receive the uncompensated bridge voltage and the temperature reference voltage to process the same and generate a compensated bridge voltage with respect to ambient temperature.

The composition includes a plurality of metal particles and a surfactant including a hydrocarbon with at least one of a hydroxyl, a carbonyl, and an amine group bonded to the hydrocarbon for reacting with the metal particles. The surfactant is present in an amount such that from about 1% to about 20% of the amount of the surfactant is adsorbed to the metal particles. The surfactant is reacted with the metal particles such that about 75% to about 100% of a maximum amount of the surfactant adsorbs to the metal particles for improving the resistance of the metal particles to oxidation and for increasing the dispersability of the magnetorheological composition in the carrier fluid. The MR composition according to the subject invention is utilized in a magnetorheological (MR) fluid.

Abstract: Activation energy, W, is determined from oil conductivity measurements to thereby provide engine oil condition from a known relationship between viscosity and W. Changes of W at a given temperature as the oil ages are reflective of changes in viscosity of the oil at the same given temperature, wherein changes in W at different temperatures are reflective of changes of viscosity at those respective temperatures as the oil ages. To determine viscosity, the temperature dependence of the oil's conductivity is measured to deduce the value of W at a given temperature. W is monitored as the oil ages. W may also be determined through the ratio of the oil conductivities at two different temperatures by techniques well known in the art by which the viscosity may be determined as the oil ages.

Abstract: A tin-lead solder alloy containing copper and optionally silver as its alloying constituents. The solder alloy consists essentially of, by weight, about 55% to about 75% tin, about 11% to about 44% lead, up to about 4% silver, nickel, palladium, platinum and/or gold, greater than 1% to about 10% copper, and incidental impurities. The solder alloys contain a small portion of CuSn intermetallic compounds, and exhibit a melting mechanism in which all but the intermetallic compounds melt within a narrow temperature range, though the actual liquidus temperature of the alloys may be considerably higher, such that the alloys can be treated as requiring peak reflow temperatures of about 250° C. or less. The intermetallic compounds precipitate out to form a diffusion barrier that increases the reliability of solder connections formed therewith.

Abstract: A vehicle door latch has a forkbolt that moves between a latched position and an unlatch position and a detent that moves between a detent position where the detent holds the forkbolt in the latched position and a release position where the detent releases the forkbolt for movement to the unlatch position. The vehicle door latch includes a detent spring that biases the detent toward the detent position and a release mechanism that moves the detent against the bias of the detent spring to the release position to release the forkbolt. The vehicle door latch also includes an auxiliary detent spring that decelerates the movement of the detent to the detent position under the bias of the detent spring to reduce noise when the detent strikes the fork bolt. An auxiliary counter spring and an alternative auxiliary helper spring are shown.
