US Patent:

7274184, Sep 25, 2007

Filed:

Dec 12, 2005

Appl. No.:

11/301571

Inventors:

Steven Thomas McCasland - Highlands Ranch CO, US
Thomas A. McCasland - Evergreen CO, US

Assignee:

TASCO, Inc. - Englewood CO

International Classification:

G01R 19/00
G01V 3/11

US Classification:

324 67, 324326

Abstract:

Systems and methods presented herein are generally directed to the location and/or identification of a circuit within a circuit. In one embodiment, a transmitter is configured for inducing a signal upon a circuit (e. g. , power lines, communication lines, lighting circuits, etc. ) to identify it from other circuit lines. The signal may be induced upon an individual element of the circuit through direct contact. A receiver may receive a radiated component of the signal from a distal point on the circuit to acquire the signal induced thereon and determine a strength of the signal received. Based on the received signal component, the receiver may determine location, configuration, and/or identification of the circuit from which the radiated signal is being received.

Assignee:

Tasco Inc. - Englewood CO

International Classification:

G01R 19/00

US Classification:

324 66, 324 67, 324528

Abstract:

Systems and methods presented herein locate and/or identify a circuit within an electrical system. In one embodiment, a transmitter is configured for inducing signals upon a plurality of circuit lines (e. g. , power lines, communication lines, lighting circuits, etc. ) with each circuit line having a unique signal to identify it from other circuit lines. Each signal may be induced upon an individual circuit line by a inductive coupling clip coupled about the circuit line. The transmitter may be used at a distribution point of the circuit lines, such as circuit breaker box. A receiver can then receive a signal from a distal point on the circuit line to acquire the unique signal induced thereon and identify determine which inductive coupling clip is coupled thereto. For example. the signal may be decoded to display a number of the circuit line being tested.

Filed:

Jan 30, 1989

Appl. No.:

7/303740

Inventors:

Thomas A. McCasland - Evergreen CO
Gilbert L. Dunn - Lakewood CO

International Classification:

B66C 304
B66F 900

US Classification:

414732

Abstract:

An auxiliary device to be mounted on a backhoe to allow gripping and lifting of objects. The device requires no additional power or operation control devices to function. The device is comprised of an opposing structure, along with appropriate linkages, which along with the bucket on the equipment is used as a gripping, crushing, or holding device.
