February 3, 2018. Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.Patent ReferencesApparatus and method for isolating and predicting errors in a local area network Methods and apparatus for alignment of images Logical event notification method and apparatus Engineering and manufacturing change control mechanism Method of controlling a manufacturing process using multivariate analysis Fault information notification system localized at each network server Generic fault management of a computer system Autonotification system for notifying recipients of detected events in a network environment Testing system with real time/off line functionality allocation Method and apparatus for predicting errors in a manufacturing process InventorsAssigneeApplicationNo. 018076 filed on 02/03/1998US Classes:700/110, Defect analysis or recognition700/32, Specific criteria of system performance700/108, Performance monitoring700/109, Quality control700/115, Product tracking (e.g., having product or carrier identification)702/81, Quality evaluation702/83, Sampling Inspection Plan702/182, Performance or efficiency evaluation702/185, Cause or fault identification714/48, Error detection or notification714/51, Control flow state sequence monitored (e.g., watchdog processor for control-flow checking)714/704Error count or rateExaminersPrimary: Gordon, Paul P.Assistant: Patel, Ramesh Attorney, Agent or FirmInternational ClassG06F 019/00AbstractA method of identifying unacceptable levels of defects in specific sections or work centers of a manufacturing process on a real time basis and initiating corrective action is disclosed. The system allows a user to define defect tolerances or thresholds for manufacturing work centers, tracks defects at the work centers, compares the level of faults with the tolerances, reports out of tolerance work centers, automatically initiates contact with the appropriate personnel to affect a correction to the out of tolerance work center, and maintains records of corrective actions taken.Field of SearchSpecific criteria of system performanceKnowledge based (e.g., expert system) Rework or engineering change Performance monitoring Quality control Defect analysis or recognition Worker or work station efficiency Product tracking (e.g., having product or carrier identification) With power supply status monitoring Error detection or notification Error forwarding and presentation (e.g., operator console, error display) Error count or rate Quality evaluation Having judging means (e.g., accept/reject) Sampling Inspection Plan Quality control Performance or efficiency evaluation Diagnostic analysis Maintenance Cause or fault identification | |
