Machine Vision Differential Measurement System
View pageUS Patent:
47108088, Dec 1, 1987
Filed:
Aug 5, 1986
Appl. No.:
6/893220
Inventors:
Leo Hoogenboom - Ballston Spa NY
Robert L. Jackson - Schenectady NY
Russell P. Kraft - Averill Park NY
Alan M. Offt - Clifton Park NY
Robert L. Jackson - Schenectady NY

Assignee:
Mechanical Technology Incorporated - Latham NY
International Classification:
H04N 718
US Classification:
358107
Abstract:
In the present system, the thickness of an object with two surfaces is determined by forming two geometric images on the surfaces in a superimposed relationship. The images are viewed by two video cameras and their relative positions with respect to two corresponding references are determined. These relative positions are used to measure the thickness of the object.

47446641, May 17, 1988
Filed:
Jun 3, 1986
Appl. No.:
6/870233

Assignee:
Mechanical Technology Incorporated - Latham NY
International Classification:
G01B 1100
US Classification:
356375
Abstract:
A system for locating a feature of an object disposed in a frame includes a spot projector for projecting a spot in the general vicinity of the feature and an imaging device with a limited field of view. The spot projector is a precision device which projects the spot towards a preselected location on the frame. When the spot and the feature are in the field of view of the imaging device, the absolute location of the feature is determined from its selective distance to the spot. Provisions are also made for determining depth or relief information about the object.
Method For Fault Diagnosis By Assessment Of Confidence Measure
View pageUS Patent:
52933237, Mar 8, 1994
Filed:
Oct 24, 1991
Appl. No.:
7/782191
Inventors:
Douglas C. Doskocil - North Reading MA
Alan M. Offt - Chelmsford MA
Alan M. Offt - Chelmsford MA
Assignee:
General Electric Company - Philadelphia PA
International Classification:
G01B 2100
US Classification:
36455101
Abstract:
A method for enabling a diagnostic system to assess, within time constraints, the health of the host system during operation, and to detect and isolate system faults during maintenance, with reduced potential for false alarms due to intermittent real faults and system noise, and for apparent misdiagnosis of the host system health, by use of a Diagnostics by Confidence Measure Assessment (DCMA) process in which a confidence measure is provided for each system test failure assessment, resulting from both the use of specialized persistence processing on many test results from a single source and the use of specialized corroboration processing on many test results from different sources.
