Abstract: A throttle lever assembly for controlling the actuation of a throttle valve in an internal combustion engine has a throttle shaft pivotally secured to a housing. An idle stop lever is mounted to and radially extends from an end portion of the shaft for engaging a depending member of the housing to stop the rotation of the throttle lever assembly at an idle position. A return cam formed of thermoplastic/thermoset material is overmolded the end portion of the shaft and a portion of the idle stop lever. The molded return cam has a channel disposed about its cam surface for receiving an accelerator cable, a stud extending axially from the outer surface of the cam return, and a spring retainer extending axially from the inner surface of the return cam for maintaining a return spring in coaxial relationship with the shaft. The return cam may also include an idle stop member to replace the discrete idle stop lever.

Abstract: An improved vehicle active brake control based on an estimate of vehicle yaw rate, wherein the estimate is based on the speeds of the un-driven wheels, but compensated to reflect slipping of the un-driven wheels during braking. Prior to braking, the yaw rate is estimated solely on the basis of the measured speeds of the un-driven wheels. During braking, the slip speeds of the un-driven wheels are estimated based on the measured speeds, the reference speed of the vehicle and the previous estimate of yaw rate, and used to compute a new yaw rate that is compensated for the estimated slip speeds.

Abstract: A side impact air bag with a self-tensioned lower edge to prevent the occupant from ejection during a rollover event or subsequent impact, A side air bag is secured to the vehicle roof rail between the front and rear pillars. A pair of tethers are secured to the air bag at a lower portion thereof and one each in turn secured to the front and rear pillars. A plurality of substantially inverted V-shaped zero length tethers extend from the lower portion to define a plurality of chambers, which when inflated cause the lower portion of the air bag to shrink and induce tension therein and to the tethers. When the side impact air bag is inflated the air bag positions itself between the occupant and vehicle window and is held in place by the tension created by the inflated sections.

Abstract: A vacuum booster for a vehicle brake system provides a working pressure valve seat on a valve member axially movable with respect to an input member. A rotary electric motor within the booster has an output shaft coupled through rotary to linear motion conversion apparatus to move the valve member with its working pressure valve seat relative to the input member. The combination of elements is designed as a drop-in replacement for a standard air valve member. The motion conversion apparatus provides much greater mechanical force than a linear solenoid; and this allows a more straightforward design of the valve arrangement, particularly the use of a high friction seal such as a simple "O"-ring in a groove. In further contrast to a linear solenoid, it further provides positive control of the working pressure valve seat position and an extended range of travel with constant force throughout the range.

Abstract: An electric motor actuator used in an environment of varying loads for varying time periods is efficiently designed to a predetermined specification in terms of both motor load and time and operated up to but not exceeding this specification over the full expected operating range. A motor load signal is low pass filtered with a plurality of time constants spanning a range of expected motor operation to generate a plurality of filtered motor load signals each associated with one of the time constants. Each of these filtered motor load signals is compared with a predetermined reference value corresponding to the associated time constant. If one or more of the filtered motor load signals exceeds the predetermined reference value with which it is compared, the one that so exceeds by the greatest margin is selected. A command current limit factor is derived from the selected filtered motor load signal and used to limit the commanded motor current.

Abstract: An improved method of manufacturing thick film circuit wherein an IC is attached to a central conductor pad with adhesive, and wherein spreading of the adhesive is constrained by a ring of porous dielectric material formed between the central conductor pad and the peripheral conductor pads to which the IC terminals are bonded. When the adhesive material is printed and begins to spread, it contacts the porous dielectric ring, which absorbs the adhesive material and stops the spreading. In this way, the porous dielectric ring controls the dimensions of the cured adhesive, thereby preventing the adhesive from contaminating the peripheral conductor pads. Even with the addition of the intervening dielectric ring, the length of the wire-bond connections and the overall dimension of the IC and its conductor pads are both significantly decreased, contributing to improved circuit area utilization and wire-bond durability.

Abstract: An improved vehicle active brake control based on an estimate of vehicle yaw rate and slip angle, wherein the estimate is based on a weighted average of two yaw rate values developed with two different estimation techniques. In general, the first estimate of yaw rate is based on the relative velocity of the un-driven wheels, and the second estimate is based on a measure of lateral acceleration. Confidence levels in each estimate are determined and used to form a third or preliminary yaw rate estimate based on a weighted average of the first and second estimates, and the third estimate is supplied to a closed-loop nonlinear dynamic observer which develops the final estimate of yaw rate, along with estimates of lateral velocity and side-slip angle.
