US Patent:

6701771, Mar 9, 2004

Filed:

Jul 17, 2001

Appl. No.:

09/907412

Inventors:

James David Frost - Atlanta GA
Jason Theodore DeJong - Davis CA

Assignee:

Georgia Tech Research Corporation - Atlanta GA

International Classification:

G01N 300

US Classification:

73 9, 73 84

Abstract:

Disclosed are apparatus and method for determining interface strength in situ. In one embodiment, the apparatus includes a plurality of load cells, wherein each load cell obtains an in situ measurement of interface strength at each measurement depth that corresponds to location of each load cell on the attachment module. Each load cell obtains the in situ measurement of interface strength without using the measurement data of a penetrating tip member. In another embodiment, an apparatus for determining interface strength in situ comprises an attachment module coupled to a penetrating tip, wherein the attachment module includes a plurality of load cells. Each load cell includes a friction sleeve, which the friction sleeve of at least one load cell is configured with a different surface texture than another load cell.

International Classification:

G01L 11/00

US Classification:

73784, 73 9

Abstract:

An apparatus and methods for determining in situ pore fluid and soil properties at a particular subsurface location are disclosed. In one embodiment, the apparatus comprises a penetrating tip member configured to penetrate soil. The apparatus further comprises an attachment module coupled to the penetrating tip member. The attachment module includes at least one mandrel that includes a piezo sensor. An in situ measurement of pore pressure is obtained by the piezo sensor at a depth that corresponds to the location of the at least one mandrel on the attachment module.

G06Q 99/00

US Classification:

705010000, 705001000

Abstract:

Systems and methods for monitoring and reporting data collected from a remote location are disclosed. A work order, defining a target to be inspected at a remote site and including an inspection plan for collecting target inspection information, is generated on a base-station system and transferred to a portable computing system. Inspection data is collected pursuant to the inspection plan on the portable computing system. Inspection data is transferred from the portable computing system to the base-station system for storage and the generation of related reports.
