Abstract: A variable pressure oil pump assembly for use with a vehicle having a controller includes a pump body having an inlet, an outlet, a valve chamber, a first passage disposed between the inlet and the valve chamber, and a second passage disposed between the outlet and the valve chamber. The assembly further includes a pressure relief valve subassembly having a movable plunger that is disposed at least partially in the valve chamber for controlling flow of oil through the valve chamber so as to control outlet oil pressure at the outlet. A plunger adjustment mechanism is associated with the valve subassembly and adapted to communicate with the controller. The plunger adjustment mechanism is operable to control movement of the plunger based on control signals provided by the controller.

Abstract: A coupling assembly 10 which selectively causes a primary mass or flywheel 20 be engaged or be coupled to a crankshaft 18 as a transmission gear assembly 23 moves from a first gear position to a second gear position and which further selectively causes the primary mass or flywheel 20 to be disengaged or disconnected from the crankshaft 18 as the vehicle is accelerated from an idle state, effective to decrease or substantially eliminate acceleration lag.

Abstract: A system, and method of its use, provides for detecting patterns that exist within a geographic area due to the presence of an orderly array of objects. In a preferred embodiment, the system uses an irregular array of transceivers to illuminate an area suspected of containing a minefield. Typically, these minefields are arranged in an orderly arrangement. Exploiting the Bragg Effect, the transceivers, each configured as a surface wave radar, illuminate an area with RF energy that is scanned in carrier frequency within the HF band (3-30 MHz) at a pre-specified interval. At the frequency that corresponds to the Bragg Effect, a significantly increased signal level occurs that indicates the presence of a pattern such as one might expect from reflections from numerous objects arranged orderly. By processing these returns judiciously, the minefield's size, location, perimeter, and even the location of individual mines may be determined.

Abstract: A vibration absorption assembly 12 and method for making the same having a base portion 30 which is movably connected to an intermediate portion 32 and to a top portion or cover 32. Assembly 12 contains several apertures or cavities 26 which operatively contain a pair of balls or spherical members 28 which absorb or dampen the vibrations emanating from a rotating member, such as a diesel fuel injection pump 14. Oil 27 is communicated into apertures 26 and is effective to lubricate the moving members 28. Further, portion or member 32 is selectively movable to allow access to several of the cavities or apertures 26 in order to allow fuel injection pump 12 to be removed from the engine 10 by use of fasteners 80, 82, and 84.

Abstract: The present invention provides a method of performing an instantaneous moisture concentration measurement of a gas having a rapidly changing moisture concentration. This method has direct application to a method of determining the drydown characteristics of an environment in which a series of instantaneous moisture concentration measurements are made during the drying of the environment. In accordance with the present invention, a standard gas is generated having a known moisture concentration estimated to be essentially equal to the instantaneous moisture concentration of the gaseous fluid (which could be a purge gas used in drying an environment) at a selected instant of its rapidly changing moisture concentration. The standard gas is then sampled. At the selected instant, the gaseous fluid is sampled and its instantaneous moisture concentration is compared with the known moisture content of the standard gas.
