  • Publication number: 20030057395
    Abstract: A magnetorheological fluid formulation in which the base liquid is optimized to exhibit an acceptable viscosity, a low volatility, improved low temperature flow properties, and an improved elastomeric compatibility. The fluid formulation includes a base liquid containing a mixture of 1-dodecene polyalphaolefin and a diester, such as dioctyl sebacate. The diester is added to the mixture in an amount effective to produce seal swelling and to lower the pour point. The viscosity of the fluid formulation is suitable for diverse vibration damping applications that require a vibration damping device to operate in the temperature range of about −40° C. to about 100° C. The low volatility and seal swelling properties of the fluid formulation reduce, inhibit or eliminate fluid loss about the seals of the vibration damping device.

  • Patent number: 6537099
    Abstract: A tamper proof electrical connector has a plug which inserts into a receptacle housing. A leading portion of the plug resides within the receptacle housing and a unitary trailing portion of the plug projects outward from the housing. A tab projects laterally outward from the receptacle housing and snap locks to a cantilevered member engaged unitarily to the trailing portion of the plug. A barrier wall projects laterally outward from the receptacle housing and substantially surrounds the cantilevered member and tab. A hood has a perimeter wall and a resilient hinge engaged to a base of the cantilevered member. When assembled, the perimeter wall of the hood surrounds the barrier wall of the receptacle housing. Two prongs project downward from a top portion of the hood snap locking to opposing first and second walls of the barrier wall disposed on either side of the tab. The first and second walls are disposed between the perimeter wall and the respective first and second prongs of the hood.

  • Patent number: 6536565
    Abstract: A rotary damper for use in motor vehicle suspensions comprising a rotor disposed within damping fluid in a fluid chamber of a case to form fluid volumes, with valves for flow control and an accumulator for fluid fill variation and thermal expansion mounted internal to the rotor. A first check valve and first control valve mounted in a first flow passage within the rotor allow flow from second fluid volume to first fluid volume, but restrict flow from the first fluid volume to the second fluid volume. Similarly, a second check valve and a second control valve mounted in a second flow passage within the rotor allow flow from the first fluid volume to the second fluid volume, but restrict flow from the second fluid volume to the first fluid volume. Thus, the valves are configured to provide independent control of damping for each direction of rotation.

  • Patent number: 6538429
    Abstract: An angular position sensor assembly for a vehicle generator shaft includes one magnet and three magnetic field sensors placed within a housing. The sensors are disposed on a circuit board that is parallel to the end of a generator shaft. The sensors are configured so that signals from the sensors are out-of-phase by predetermined angles. The generator shaft alternatingly forms plural slots and plural teeth. As the shaft rotates, the slots and teeth cause a change in a magnetic field around each sensor. By sensing the changes in the magnetic field, the position of the shaft can be determined from the out of phase signals received from the sensors.

  • Patent number: 6537892
    Abstract: A method of glass frit bonding wafers to form a package, in which the width of the glass bond line between the wafers is minimized to reduce package size. The method entails the use of a glass frit material containing a particulate filler material that establishes the stand-off distance between wafers, instead of relying on discrete structural features on one of the wafers dedicated to this function. In addition, the amount of glass frit material used to form the glass bond line between wafers is reduced to such levels as to reduce the width of the glass bond line, allowing the overall size of the package to be minimized. To accommodate the variability associated with screening processes when low volume lines of paste are printed, the invention further entails the use of storage regions defined by walls adjacent the glass bond line to accommodate excess glass frit material without significantly increasing the width of the bond line.

  • Patent number: 6533314
    Abstract: According to the present invention, an instrument panel having an instrument panel cover including a hidden deployment region integrally formed within an inner surface thereof by an ultrasonic embossing process is provided. More specifically, the deployment region comprises at least one and preferably a plurality of scores or cuts formed in the inner surface according to a predetermined pattern. The scores represent weakened portions of the instrument panel cover designed so that the force of an inflating air bag cushion causes the instrument panel cover to separate along the scores to thereby provide an opening for the inflating air bag cushion to deploy therethrough and be directed into the passenger compartment of a vehicle. The deployment region may be defined by any number of scores and therefore may have a variety of patterns, including but not limited to “H” pattern, “U” pattern, and “I” pattern.
