Testing and Development of Extended Range Straightness Monitor Systems
نویسنده
چکیده
This is essentially an archival document that summarizes the results of several tests performed at the Draper Laboratory on extended-range straightness monitor systems during the GEM Muon Alignment R&D activity. Two systems are discussed; standard 3-point LED/Lens/Quad-cell Straight Line Monitors (SLM) with multi-LED blocks, and the Video Straightness Monitor (VSM). Included are measurements of thermal sensitivity, turbulence effects, resolution dependence on lens width, defocus tolerance, VSM mask illumination, measurement of VSM mask rotation, and a discussion of component mounting/calibration.

Miniature monochrome video cameras made by Chinon and VVL Corporations are reviewed for application as sensors in Video Straightness Monitor systems. Test frames and scans are presented for three different cameras in a VSM system running across an 8-meter optical baseline.
متن کاملDeveloping new methods to monitor phase II fuzzy linear profiles
In some quality control applications, the quality of a process or a product is described by the relationship between a response variable and one or more explanatory variables, called a profile. Moreover, in most practical applications, the qualitative characteristic of a product/service is vague, uncertain and linguistic and cannot be precisely stated. The purpose of this paper is to propose a ...
متن کاملAnalytical Performance and Quality Control of a Glucose Monitor System
Background and Objective: The reliability and validity of monitors for self-monitoring of blood glucose are debated. We evaluated the analytical performance of Accu-check Active (Boehringer Mannheim, Roche) which is one of the most commonly used monitors in Iran. Material and Methods: We compared the monitor readings with the reference values by percentage of values within...
متن کاملA scalarization-based method for multiple part-type scheduling of two-machine robotic systems with non-destructive testing technologies
This paper analyzes the performance of a robotic system with two machines in which machines are configured in a circular layout and produce non-identical parts repetitively. The non-destructive testing (NDT) is performed by a stationary robotic arm located in the center of the circle, or a cluster tool. The robotic arm integrates multiple tasks, mainly the NDT of the part and its transition bet...
متن کاملUsing Program Slicing Technique to Reduce the Cost of Software Testing
Systems of computers and their application in the lives of modern human beings are vastly expanding. In any kind of computer application, failure in computer systems can lead to a range of financial and mortal losses. Indeed, the major origin of software failure can be located in designing or implementing software. With regard to these statistics, 30% of the software projects have been prospero...
