Scanning Apparatus And Method For Non-Destructive Materials Evaluation And Mapping Through Use Of Acoustic Waves
US Patent:
5404755, Apr 11, 1995
Filed:
Apr 10, 1992
Appl. No.:
7/867248
Inventors:
Larry D. Olson - Lakewood CO
Dennis A. Sack - Boulder CO
David Fidelman - Lakewood CO
Dennis A. Sack - Boulder CO
David Fidelman - Lakewood CO
Assignee:
Olson Engineering, Inc. - Golden CO
International Classification:
G01N 2924
US Classification:
73639
Abstract:
Columns, walls and other solid structures of concrete, wood, masonry or other materials are non-destructively tested by acoustic signals transmitted from a carriage. The carriage has a frame which is wheel mounted to move over the surface of the test candidate. An internally-mounted piezoelectric crystal roller as an acoustic signal generator or receiver is suspended from the carriage with two degrees of spring freedom to allow accommodation of irregularities in the test candidate surface. The assembly including the piezoelectric crystal roller and its flexible mounting are configured as a replaceable module relative to the carriage frame. The same carriage is useable as an echo type acoustic scanner or, in combination with other devices or carriages, as either an acoustic transmitter or receiver although inclusion of elements to perform both functions within the same carriage is contemplated. The carriage frame can also mount one or more hammer mechanisms to impact the test candidate surface at regular intervals as the carriage moves along the specimen surface. The device is suitable for detecting or generating compression, shear or surface waves in the test specimen.
Parallel Seismic Depth Testing Using A Cone Penetrometer
US Patent:
7152467, Dec 26, 2006
Filed:
Mar 17, 2004
Appl. No.:
10/802625
Inventors:
Scott H. Slaughter - Mobile AL, US
Larry Olson - Golden CO, US
Larry Olson - Golden CO, US
International Classification:
E21B 47/04, G01B 17/00
US Classification:
7315258, 702158, 702166, 175 40
Abstract:
A parallel seismic tester utilizing a cone penetrometer to test the depth of a foundation or the like comprises three important elements: the cone penetrometer which houses a receiver, an impactor to impact the structure, and data gathering and analyzing equipment. The receiver may comprise a hydrophone, a geophone, or accelerometers. In the case where the receiver is a hydrophone, the hydrophone is embedded in a plastic, water filled container within the cone penetrometer head, and the head retracts prior to running tests.
