In this paper we present a novel method for reliability testing of MEMS devices containing movable structures. A small size, simple and cheap vibration fatigue test equipment was designed and realized at BUTE and vibration fatigue tests were carried out on 10 samples of a LIS0L02AS4-type MEMS 3-axis inertial sensor provided by ST Microelectronics. The paper presents the test plan, the test equi...

FPGAs (Field Programmable Gate Arrays) are highly integrated devices that can be programmed into variable functions. The application-level testing of FPGAs usually requires multiple reconfigurations and relevant functional tests respectively through ATEs (Automated Test Equipments). However, test engineers are facing a tough problem to re-configure FPGAs automatically by an ATE instead of inter...

Madeleine R. Johnson AGMC/MAEL 813 Irving Wick Drive West Newark AFB, Ohio 43057-5149 This paper describes the initial results of a refrigerant retrofit project at the Aerospace Guidance and Metrology Center (AGMC) at Newark Air Force Base, Ohio. The objective is to convert selected types of test equipment to properly operate on hydrofluorocarbon (HFC) alternative refrigerants, having no ozone ...

The electrical system of the construction machinery usually works on circumstance of high temperature, serious vibration and shock, dust pollution as well as electromagnetic interference, so the electrical system is very likely to go wrong while compared with other systems, for example working attachment, under chassis and so on. In view of this, an advanced fault test device, with application ...

Since the equipment transmission parts of combination electric appliance in transformer substation are located in the shell, when an internal fault appears, the traditional charged test method only can preliminarily determine the defective position and types, but cannot directly shows the internal defects of the equipment. The Fuxin Company actively introduced X-ray CR imaging test technology a...

Herein, we report a case of pseudosinus tachycardia resulting from an electromagnetic interference between a mobile phone and treadmill device. Electromagnetic interference from a charging mobile phone connected to the same socket with the exercise device turned the recording of a patient to that of pseudosinus tachycardia at approximately twice the rate of actual basal heart rate. Removal of t...

The complexity of semiconductor manufacturing equipment is growing. This growth results in a complexity increase of the integration and test phase of these systems. Simply adding more test resources is not possible anymore, because of the cost involved. A better design of an integration and test strategy can help to optimize this hectic phase. However, methods to design and evaluate integration...

A calorimetric technique enables precise measurements of the surface resistance RS of superconducting samples. One of the devices exploiting this technique at multiple frequencies is the Quadrupole Resonator. Its measurement capabilities and limitations are discussed and compared with similar devices. Results on bulk niobium and niobium film on copper samples are presented. It is shown how diff...

A flocculation reaction employing a cardiolipid antigen was used for syphilis screening on Groupamatic equipment in parallel with conventional screening reactions: Kolmer CF, RPCF, Kahn, Kline, and RPR. The positive samples were confirmed by FTA-200, FTA-ABS, TPI, and in some cases by TPHA. There were 5,212 known samples which had already been tested by all methods and of which 1,648 were posit...

Most of the SDL and MSC based test generation methods and tools produce non-concurrent TTCN test cases only. If the test equipment itself is a distributed system, the implementation of such test cases is a diicult task and requires a substantial amount of additional work. In this paper, we explain how concurrent TTCN test cases can be generated directly from SDL system speciications and MSC tes...
