US Patent:

6490818, Dec 10, 2002

Filed:

Oct 20, 2000

Appl. No.:

09/694083

Inventors:

Everett Bramhall - Concord MA
Steven Carroll - Brighton MA
Mark Hazel - Concord MA
Peter Hewitt - Concord MA
Christopher Mountain - Concord MA

Assignee:

Bramhall Hazel, Inc. - West Concord MA

International Classification:

G09F 1100

US Classification:

40491, 40735, 40768, 116323

Abstract:

A versatile system which includes a display unit by which a plurality of image works selected from photographs, paintings, newspaper articles, pictures, images, prints, designs, sports memorabilia, certificates, awards, and diplomas may be viewed simultaneously or individually, as selected by the viewer. A display unit stores a plurality of image works for selective viewing by an observer by virtue of each image works being mounted on a slidable carrier, which may be slid within a framework to enable or disable viewing of image works which may be disposed behind a given slidable carrier.

Filed:

May 10, 1994

Appl. No.:

8/241031

Inventors:

J. Thomas Fowler - Marblehead MA
Steven S. Carroll - South Hampton NH

Assignee:

Gas Research Institute - Chicago IL

International Classification:

G01R 3300
G01R 3312
G01N 2772
G01N 2782

US Classification:

324263

Abstract:

An apparatus and method for detecting anomalies in ferrous pipe structures is presented. An electrical current is passed through the ferrous pipe structure so as to create a magnetic field in the pipe. A sensor having one or more sensor shoe members is placed in the interior of a ferrous pipe structure to be inspected. Each sensor shoe member has one or more magnetometer elements for detecting the magnetic fields in the region of the ferrous pipe structure adjacent to which the sensor shoe member is placed.

International Classification:

G01N 2782
G01N 2772
G01R 2772

US Classification:

324220

Abstract:

An apparatus and method for detecting anomalies in ferrous pipe structures is presented. A sensor having one or more sensor shoe members is placed in the interior of a ferrous pipe structure to be inspected. Each sensor shoe member has one or more magnetic field generating apparatus, with a three-axis fluxgate magnetometer for detecting magnetic fields in the region of the ferrous pipe structure adjacent to which the sensor shoe member is placed. Any magnetic fields in the pipe structure, whether imposed externally, or remnant, which are detected, are sensed and resolved into components in three mutually orthogonal directions for enhanced accuracy.
