US Patent:

47076313, Nov 17, 1987

Filed:

Jul 17, 1986

Appl. No.:

6/886457

Inventors:

Robert B. Stokes - Torrance CA
Kuo-Hsiung Yen - Manhattan Beach CA
Reynold S. Kagiwada - Los Angeles CA
Michael J. Delaney - Lomita CA

Assignee:

TRW Inc. - Redondo Beach CA

International Classification:

H01L 4108

US Classification:

310313A

Abstract:

A surface acoustic wave (SAW) diffraction-effect or interference-effect device with a highly isotropic substrate having a high coupling coefficient and low attenuation losses. The use of X-propagating rotated-Y-cut lithium niobate as the SAW substrate, with the Y rotation angle selected at 121 degrees, provides a practically isotropic material, with a high coupling coefficient and relatively low attenuation losses.

Torsten H. Parke - Dallas TX
Michael R. Delaney - Springfield MO

Assignee:

Mend Technologies, Inc. - Dallas TX

International Classification:

A61H 100
A61G 1300

US Classification:

5649

Abstract:

A medical stirrup supporting and positioning apparatus which provides three dimensional adjustment. The stirrup features a single locking member which simultaneously locks the stirrup into two of three non parallel planes. It also includes a free-floating boot which together with the locking device allows the stirrup to be locked in a horizontal plane and also locked in the adduction or abduction position, but the boot is still free to tilt forward and backwards between safety stop positions.

H01L 4108

US Classification:

310313A

Abstract:

A surface acoustic wave (SAW) device configured to operate as a spectrum analyzer, and having an array of input transducers disposed on a substrate in such positions as to produce a focused beam of acoustic energy at a focal arc, each position on the arc being representative of an input signal frequency. Output transducers produce electrical signals corresponding to the energy received at successive segments of the focal arc. The disclosed device includes various combinations of input transducer array improvements, some of which are to provide amplitude weighting of the input array, including aperture width weighting, capacitive weighting, resistive weighting, series-parallel weighting, and source withdrawal weighting. Another improvement in input array configuration eliminates close or overlapping electrodes of opposite polarities and thereby reduces parasitic capacitance and acoustic radiation between electrode elements. The use of curved input transducer fingers improves operation of the transducers as point sources.
