6703831, Mar 9, 2004

Filed:

Oct 3, 2000

Appl. No.:

09/677977

Inventors:

William A. Keely - Oxford MI
Randall H. Field - Rochester Hills MI

Assignee:

Quantech, Inc. - Pontiac MI

International Classification:

G01N 2772

US Classification:

324232, 324238

Abstract:

An apparatus and method for inspecting contours formed along a predetermined region of a surface on a workpiece formed of an electrically conductive material using eddy current. A probe includes a longitudinal axis and is moveable along a path of travel with respect to the predetermined region to be inspected on a workpiece. At least two coils are spaced longitudinally from one another and supported by the probe to be electrically excited with a predetermined frequency and amplitude during movement of the probe along the path. Sensors are provided for measuring the excitation voltage of each coil as eddy currents are induced in the electrically conductive material of the workpiece by the coils supported on the probe moving along the path of travel with respect to the workpiece. A comparison is performed between the measured eddy current signals from the at least two coils, where a non-zero difference after the coils have encountered the predetermined region to be tested represents an end position of the predetermined region formed on the workpiece being tested.

International Classification:

G01N 27/82

US Classification:

324240, 324238

Abstract:

An apparatus and method is disclosed for inspecting contours formed along a predetermined region of a surface on a workpiece formed of an electrically conductive material using eddy current. A probe includes a longitudinal axis and is moveable along a path of travel to a static testing position stationary with respect to the predetermined region to be inspected on a workpiece. At least two coils are spaced longitudinally from one another and supported by the probe to be electrically excited with a predetermined frequency and amplitude while at the static testing position with the stationary probe. Sensors are provided for measuring the excitation voltage of each coil as eddy currents are induced in the electrically conductive material of the workpiece by the coils supported on the probe stationary at the static testing position with respect to the workpiece. A comparison is performed between the measured eddy current signals from the at least two coils, where a non-zero difference after the coils have encountered the predetermined region to be tested represents an end position of the predetermined region formed on the workpiece being tested.

Filed:

Jun 22, 2005

Appl. No.:

11/165267

Inventors:

William Arthur Keely - Oxford MI, US

Assignee:

Defense Technology Corporation of America - Casper WY

International Classification:

H01T 23/00

US Classification:

361232

Abstract:

An electrical discharge weapon for immobilizing a live target that includes a shock circuit having a low power consumption, a high power efficiency, and/or a low weight. The shock circuit may be entirely contained in a projectile without the need for range limiting trailing wires. In one embodiment, the shock circuit includes a high efficiency circuit that recaptures an certain amount of energy that would otherwise be wasted.

US Classification:

42 108, 102502, 361232, 42 84

Abstract:

An electrical discharge weapon projectile for immobilizing a live target that includes a shock circuit having a low power consumption, a high power efficiency, and/or a low weight. In one embodiment, the projectile includes a high efficiency circuit that would reduce the weights of shock circuits while providing a more effective and safer power level, so that the circuits may be entirely contained within the projectile to eliminate the need for range limiting trailing wires.

Appl. No.:

7/438845

Inventors:

William A. Keely - Oxford MI

Frank J. Sabo - South Bend IN

International Classification:

G08B 1318
E05B 4506

US Classification:

340567

Abstract:

A security system has a wall mounted assembly for installation adjacent an entry door and includes a motion detector for sensing intruders, an alarm for sounding a warning, an alarm circuit, a radio receiver responsive to two codes, and an electric door striker. A portable miniature transmitter has two transmission codes to activate the receiver, one for toggling the alarm circuit between armed and disarmed condition and for releasing the door upon disarming the alarm circuit. When the circuit is armed the motion detector is able to activate the alarm. The second transmission code activates the alarm if the circuit is armed. Remote self contained motion detector and transmitter units for use in other rooms use the second code to activate the alarm when motion is detected by those units.
