Abstract: A system (1) for measuring the quality and level of lubricant in an engine lubricant reservoir (5) includes valve means (26) for selectively directing a portion of lubricant from the engine (2) through a first conduit (25) for return to the engine or through a second conduit (31) for removal from the engine. Within the first conduit are one or more sensors (28) for sensing the condition of the lubricant passing through the first conduit. The sensors are monitored by a controller (30) which is operative selectively to cause the valve (26) means to block the flow of lubricant through the first conduit and direct a portion of the lubricant through the second conduit (31) based on the monitored conditions of the lubricant. Also, the controller (30) directs a supply of fresh lubricant to the engine in response to the lubricant in the engine lubricant reservoir dropping below a predetermined level. The lubricant flowing through the second conduit may either be stored in a lubricant reservoir (32) and if desired subsequently intermittently mixed with the fuel in the fuel tank (11), or caused to flow directly to the fuel tank on command of the valve means by the controller which limits the amount of lubricant that can be added to the fuel tank so as not to exceed a predetermined lubricant/fuel ratio for the engine.

Abstract: The relative motion and force between two interconnected elements can be controlled by a semi-active damper to minimize the instances of the motion exceeding acceptable limits, while maximizing isolation between the elements. Applying an algorithm to the control parameters of the damper provides excellent isolation from input vibration and shocks. The dampers and control algorithms are useful in primary vehicle suspension systems, cab mounts, seat mounts, and engine mounts.

Abstract: A viscometer for sensing or characterizing the stress required to shear a fluid at a given rate includes a pair of members coaxially mounted for relative rotation. Between the members is an annular gap defining a flow pat h for the fluid. The flow path is configured such that during differential rotation of the members, fluid is caused to flow through the annular gap tha t is a function of the differential rotation and the viscosity of the fluid. A sensor measures the torque or torque equivalent required to achieve such differential rotation between the members.
