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.

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.

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.

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.
