Appl. No.:

10/195708

Inventors:

Robert W. Cribbs - Placerville CA
Ching-Chen Wu - Folsom CA
Douglas G. Niessen - Folsom CA

Assignee:

Gas Research Institute - Des Plaines IL

International Classification:

G01R 3320

US Classification:

73598

Abstract:

A method and system for detecting an underground obstacle in which a plurality of acoustic signal sensors are deployed in a predetermined pattern on an area of ground defined by a guided drill path. A drill head of a drill is inserted into the ground and a borehole is drilled in the ground along the guided drill path. The noise signal generated by the drill head is detected at at least two of the acoustic signal sensors and the difference in arrival time of the noise signal at the two acoustic signal sensors is determined. This difference in arrival time of noise signal is analyzed, whereby the presence or absence of an underground obstacle is determined.

International Classification:

G01S 1500

US Classification:

367 99

Abstract:

An apparatus and method for detecting utilities buried in the ground wherein an array of sonic receivers are arranged in rows and ranks against the ground and a corresponding array of sonic transmitters are arranged relative to the array of sonic receivers so that a distance between each sonic transmitter and each adjacent sonic receiver is the same. Echoes generated by the apparatus may then be normalized, averaged and compared to the original echoes to develop a profile of the buried utility.

Abstract:

A system for the destruction of adipose tissue utilizing high intensity focused ultrasound (HIFU) within a patient's body. The system comprises a controller for data storage and the operation and control of a plurality of elements. One elements is a means for mapping a human body to establish three dimensional coordinate position data for existing adipose tissue. The controller is able to identify the plurality of adipose tissue locations on said human body and establish a protocol for the destruction of the adipose tissue. A HIFU transducer assembly having one or more piezoelectric element(s) is used along with at least one sensor wherein the sensor provides feed back information to the controller for the safe operation of the piezoelectric element(s). The sensor is electronically coupled to the controller, and the controller provides essential treatment command information to one or more piezoelectric element(s) based on positioning information obtained from the three dimensional coordinate position data.

International Classification:

G10L 500

US Classification:

381 36

Abstract:

Speech analysis is performed by synchronizing, with the initiation of glottal pulses produced during the voicing of phonemes, a pitch-independent transform that performs analysis entirely within a pitch period. Analysis is made of the three most dominant formant frequencies of the sound sets involved in the enunciation of voiced phonemes. Peaks in the transform represent formant frequencies. Three peaks are selected from the transform identifying the frequencies with the first, second and third greatest amplitudes. Correlation of the waveform between successive pitch periods detects whether a sound is a vowel, a voiced sibilant, or unvoiced. Unvoiced sound sets are similarly analyzed but the analysis is synchronized with artificially generated synch pulses. The sound sets are analyzed to determine (1) whether the sound is a vowel, a voiced sibilant or an unvoiced sound; (2) the primary formant frequency, i. e. the one with the greatest amplitude; (3) the substantial presence of secondary and tertiary formant frequencies with the next two largest amplitudes, as well as their frequencies; (4) the frequency ratios of the primary to the secondary and the primary to the tertiary frequencies; (5) the decay rate of at least the greatest formant frequency; and (6) the time relationships of these sound sets to one another and to unvoiced sounds.

International Classification:

G01N 2900

US Classification:

73626

Abstract:

A small, simple, yet accurate probe for producing a sector scan for ultrasonic medical diagnostic apparatus is provided by positioning a curved transducer array within the probe opposite a window, and filling the probe with a fluid having an acoustic velocity on the order of 0. 5. times. 10. sup. 5 cm/sec. This combination is made possible by forming the window from a stiff polyionomer material whose acoustic velocity is closed to that of human skin, yet which is stiff enough even when thin to be essentially non-deformable in clinical use. Grating lobes of the ultrasonic beam, as well as the scatter produced within the probe by the high reflectivity of the window material, are absorbed by coating or lining the inner side walls of the probe with an open-celled polyether urethane foam having a cell diameter slightly smaller than one wavelength of the ultrasound in the probe fluid.
