    摘要: Acoustic heterodyne radars use accurately surveyed or otherwise known locations to repetitively launch at least two, intense acoustic tone soundwaves (F1, F2) into an underground area of search. An acoustic receiver is tuned to receive either the sum (F1+F2) or difference (|F1−F2|) heterodynes and is configured to measure and log the overall relative attenuation and roundtrip travel times of the soundwaves, like a typical radar. Any acoustic heterodynes received are assumed to be the work of non-linearities and stresses in the search area. A full-waveform three dimensional tomography algorithm is applied by a graphics processor to the collected and logged data to generate maps and profiles of objects beneath the ground which are interpreted to have produced the acoustic heterodynes.

    摘要: An unsynchronized acoustic or radio-frequency (RF) computed tomography (CT) imaging system with matched, but independent, continuous wave (CW) transmitters and receivers configured to radiate acoustic or RF transmissions in a plurality of vector paths through solid geologic material. A computer calculates and displays tomographic images constructed from individual acoustic or RF path signal travel time or attenuation measurements logged from registered locations from the CW transmitters and receivers after their being shuttled amongst a number of different transmitter and receiver perspectives available around said geologic material to generate data necessary for computed tomography. Each of the transmitters and receivers include independent unsynchronized crystal oscillators rated at 10-ppm or better frequency uncertainty to produce and to detect CW radio frequency (RF) transmissions.

    摘要: An apparatus for pivotally fixing a non-driven wheel assembly to a vehicle frame is disclosed. The apparatus provides a trough through which non-driven wheel assembly components can be passed and protected. In one embodiment, the trough is circular in shape and is fully enclosed by the apparatus. In other embodiments, the trough has various shapes and comprises retaining members to secure and protect non-driven wheel assembly components. A suspension system interface is provided that allows the apparatus to suspend the non-driven wheel assembly. Openings used to pivotally and rigidly fix a mounting plate, suspension system, pivotal axes, and fender assemblies are also disclosed and claimed herein.

    摘要: An analog control circuit is coupled to an apparatus having a variable characteristic over an operating range. A sensing circuit is coupled to the apparatus and the control circuit during the range of operation of the apparatus and is operative to sense the variable characteristic. The operating parameter of the apparatus is controlled to be set at a level corresponding to a prescribed criterion, which may be a maximum or minimum, of the characteristic sensed over the range of operation.
