Testing for minimum resolvable temperature (MRT), a subjective test technique used to demonstrate the performance of thermal imaging sensors with human observers, is addressed. The results of automated MRT testing are presented and compared with those of traditional MRT testing for the same thermal imaging sensor. The theory of MRT as it relates to automated testing is described. The reasons for developing automated MRT testing are explored, as is the motivation for promoting acceptance of this kind of testing 相似文献

The approach of the Year 2000 (Y2K) has called into question the condition of readiness of computer systems upon which organizations depend. Will these systems operate reliably after midnight, January 1, 2000, or will problems associated with date calculations cause failures that adversely affect users? This question has caused organizations to identify their critical systems, test these systems for Y2K problems, and take corrective action where necessary to ensure Y2K readiness. This paper examines various technical and management issues that Southwest Research Institute has dealt with in solving these problems 相似文献

Since the DoD was the leader in incorporating transistors, ICs and embedded processors, they also were on the forefront in developing automatic test equipment. The term automatic test equipment (ATE) encompasses all phases of computer controlled testing. It is based on the integration of instruments, computers and software. These systems generally include five basic elements: control, stimulus, measurement, switching and software. A special interface device or interface test adapter connects the unit under test (UUT) to the ATE. Test program software connects the ATE to the appropriate UUT test points, programs the input stimulus and monitors the output response 相似文献
