Abstract: In general, in one aspect, a measurement system has measurement instrument having a first and second component. The first component is mechanically coupled to a first point on a shaft. The second component is mechanically coupled to a second point on the shaft. The measurement instrument is configured to generate an electrical displacement signal indicative of a displacement between the first and second components. A processor is in data communication with the measurement instrument, and the processor configured to: receive the displacement signal from the measurement instrument; receive a velocity signal indicative of a velocity; and based on the displacement signal and the velocity signal, produce an electrical power signal indicative of at least one of a torque applied to the shaft, or a power applied to the shaft.

Abstract: A housing is arranged to include a plurality of rows of projecting cutting wheels for projection into a bush to be cut, with the housing further including cutter knives mounted between adjacent coplanar pairs of the cutting wheels to effect the comminuting of brush and the like directed within the housing.

Abstract: The present invention relates to a light weight, high performance bumper for automobiles and the like. It consists of an I-beam reinforced by one or more ribs which add support to the front wall. The bumper is fabricated from fiber reinforced thermoplastic or thermoset materials.

Abstract: The door inner and outer panels are detachably attached to one another to permit separation to access the space therebetween containing the door hardware. A device mounts the door inner panel and the door outer panel on the vehicle body for independent hinging movement so that the panels move between door open and door closed position in unison with one another when the panels are attached, and the detachment of the panels from one another permits the outer panel to swing away from the inner panel to provide unobstructed access to the door hardware mounted in the space between the panels. The inner and outer panels may be constructed of molded plastic and with one panel having a receptacle receiving the door guard beam and the other panel having an integral molded structure receiving the receptacle upon attachment of the panels together so that the door guard beam becomes effectively coupled with both of the panels.
