Vibration testing is widely accepted as a method to improve product quality by identifying structural weaknesses. Historically, single axis, single shaker testing is the method of choice. This is largely due to the lack of economical and effective test hardware and control software. Significant advances have been made in both arenas, resulting in test equipment design that permits multiple shak...

− This paper is focused on comparison of three proposed methods for testing the modules and the complex installations of distributed systems (fieldbuses) for the use in a harsh industrial environment and applications, where the system reliability is a crucial requirement. The methods are defined, their advantages and disadvantages are explained and expected test results are presented. Special a...

Use data processing technology, storage transmission network automated instrument analysis technology information management quality control. The realizes collection, processing, storage, transmission, summarization various businesses, provides q...

A major problem for applying self-test techniques to MEMS is the multi-domain nature of the sensing parts that require special test equipment for stimuli generation. In this work we describe, for three different types of MEMS that work in different energy domains, how the required non-electrical test stimuli can be induced onchip by means of electrical signals. This provides the basis for addin...

The possibility of using window comparators for the on-chip evaluation of signals in the analogue circuit part has been demonstrated and is shortly summarised. One of the problems is the lot-to-lot variation of the comparator window. An automatic window repositioning technique is detailed that allows to compensate the window shift. The components for the implementation comprising a reference co...
