    Abstract: A structural assembly (12) that measures forces along and moments about three orthogonal axes (76, 78, 64) including a longitudinal axis (64) with very low 'cross talk' where one axis is affected by loads along or about another axis. The support structure (44) is substantially compliant for moments about the longitudinal axis (64) and substantially rigid for forces along the orthogonal axes (76, 78, 64) and for moments about the non-longitudinal orthogonal axes (76, 78). A torque cell (46) that measures moments about the longitudinal axis (64) is positioned concentrically about the longitudinal axis (64) either within a cavity (60, 62) of the support structure (44) or around the support structure (44). Upper (48) and lower (50) flexure diaphragms connect adjacent ends of the support structure (44) and the torque cell (46) and transmit moments about the longitudinal axis (64) to the torque cell but are compliant to axial forces and moments about the non-longitudinal orthogonal axes (76, 78).

    Abstract: An extensometer (10) for measuring strain in a specimen (35) on which the extensometer (10) is mounted which has two arms (11, 12) joined together at first ends, and with specimen engaging knife edges (31, 32) at the second ends. The knife edges (31, 32) will engage a specimen (35) at spaced locations, so that when the specimen (35) is subjected to a load, the knife edges (31, 32) will separate, and the amount of separation will be an indication of the strain in the specimen. The distance between the knife edges is known as the 'gage length' (34, 78, 80, 100, 102, 122) and the extensometer provides a mounting (11B, 12B, 36, 84) for the knife edges (31, 32) in a plurality of positions so the gage length (34, 78, 80, 100, 102, 122) of the extensometer is changed as needed.

    Abstract: A measurement system for remotely measuring a parameter and relative distance having a parameter sensor (10-13) providing signals to control the pulse repetition rate of a pulse generator (24), the pulses from the pulse generator (24) in turn controlling a switch (25) to alternately connect and disconnect an energy storage device (26) to the input of a sonic waveguide device (31). The output signals at the outputs of the sonic waveguide device (31) control a driving device (38) which provides a representation of these output signals on a transmission line arrangement (43 and associated components).

    Abstract: An extensometer assembly (10) accurately measures axial strain, torsional strain and various combinations of these strains in a specimen (12) on which the extensometer assembly (10) is mounted. The torsional strain measurement is made by measuring angular displacement about the longitudinal axis (20) of the specimen (12) with one extensometer (13) at the same time separately measuring the elongation of the specimen (12) with a separate extensometer (11) linked to the torsional measuring extensometer (13) by supports (15, 16, 17) having the necessary degrees of freedom so that readings from the respective extensometers (11, 13) are not subjected to excessive "cross talk", and at the same time torsional movement between the extensometers (11, 13) about an axis perpendicular to the longitudinal axis of the specimen is resisted.

    Abstract: A Magnetostrictive linear position sensor (14) produces a signal which is a time period. It is sometimes required to measure this time period, and provide an output in another form which accurately represents the time period. The final output may be a voltage, current, frequency, digital, or other signal format. A time period is commonly measured using a clock and a counter. The resolution is limited by the frequency of the clock. An upper limit for the clock frequency is usually set based on power consumption, or other circuit constraint. The present invention discloses a method and apparatus (10) for improving the resolution of a time interval while using low power and for providing a response after one time period without averaging.

    Abstract: A road simulator (10) for testing components of automobiles using a wheel assembly (13, 14), including a tire (14) that is to be loaded by simulation of actual road forces. A low mass flexible web harness (70) is placed over the tire (14) and has web extensions (72A, 72G) loaded in tension in at least one lateral direction for simulating forces transmitted to the tire (14) at the tire patch without having any substantial mass applied to the tire (14). High strength, low mass webs (72) are used for the loading link (72A, 72G) and harness (70), such as a nylon, Aramid fibers, or carbon filament materials. The harness (70) permits simulating very closely the actual friction forces on a tire (14), particularly in relation to lateral direction loading without having test fixture mass affect the test.
