Abstract: A thrust bearing assembly includes upper and lower bearing halves for journaling a shaft therebetween. At least one thrust washer is arranged on the outer surface of at least one of the bearing halves and has ends which extend beyond and confront the ends of the bearing half on which the thrust washer is mounted to support it against rotational movement relative to the bearing half. A bearing half can have such thrust washers, in which case the other bearing half is narrower and is retained axially by the ends of the thrust washers of the opposing bearing half, or a thrust bearing can be provided on each of the bearing halves in axially opposed relation to one another.

Abstract: A structure and related method for determining the uncertainty window associated with clock signals on a microprocessor using circuitry on the microprocessor die itself and external software. A target clock signal of interest is compared to a series of reference clock signals having the same frequency, but differing in phase relationship. Where the target clock signal makes state transitions with respect to the various reference clock signals over the course of several thousand comparisons is indicative of the uncertainty window for that target clock. By adjusting the phase relationship between the reference clock signals, and thereby adjusting the width of the time windows defined by corresponding features of the reference clock signals, the uncertainty window for the target clock signal may be iteratively determined.

Abstract: The subject invention provides a thrust bearing assembly having only three thrust flanges in total. One portion of the thrust bearing assembly comprises a main bearing having an arcuate bearing shell with a concave inner surface and a convex outer surface. A thrust washer having hydrodynamic features abuts one of the edges of the main bearing and extends radially outwardly from the outer surface thereof forming a thrust surface. The other of the edges of the main bearing is free of a flange. The free edge of the main bearing is preferably spaced inward from other thrust surfaces and the edge has a substantially narrower width than the other thrust surfaces.

Abstract: An engine bearing for an internal combustion engine has a pair of separately constructed bearing halves comprising a pair of arcuate shells having a pair of laterally spaced flanges extending generally radially outwardly from each shell. Each pair of laterally spaced flanges comprises a pair of thrust faces facing generally away from one another with one of the thrust faces comprising an undulating contoured surface and the other thrust face having a generally planar non-contoured surface. The engine bearing is assembled having the contoured surface of one engine bearing half abutting the non-contoured surface of the other engine bearing half so that the engine bearing has generally opposite sides comprising both contoured and non-contoured surfaces.
