− Equipment interoperability is a key factor for the development of Digital Subscriber Line (DSL) technologies and services. The paper describes the efforts of TLC Sannio Testing Laboratory [1] in acquiring knowledge and competences for the validation of DSL equipment against standard requirements.

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...

Extending or changing systems that are in operation 24/7 should disturb the operation as little as possible. Therefore, the extensions or changes should have been thoroughly tested in advance under conditions comparable to operational conditions. Baggage handling systems is typically an area to which these requirements apply. Control software is one of the main components for baggage handling s...

Many different types of mobile equipment used in surface coal mining utilize enclosed cabs to protect equipment operators. The overburden removal process is extremely dusty and can cause excessive exposure to respirable dust, especially crystalline silica. After equipment is used for years, many components of the enclosure deteriorate and its effectiveness is greatly reduced. This report discus...

Caterpillar has for many years used telemetry as a key component in the data acquisition and analysis systems used to test and develop heavy equipment. The testing of construction and mining equipment at Caterpillar presents several unique challenges, such as the operating environment of the test machine, the large number of models in the product line, the need to change test machines on a dail...

In a variety of situations, an undesired shock excitation is applied to a master structure that supports shock-sensitive equipment. Often, one wishes to design and test a master structure that transmits the least amount of shock energy to the attached equipment. In scaled testing of new designs, a major task is to design and construct “equipment emulators” – inexpensive mechanical systems which...

We present the first delay-fault testing approach for Field Programmable Gate Arrays (FPGAs), applicable for on-line testing as well as for off-line manufacturing and system-level testing. Our approach is based on Built-In Self-Test (BIST), it is comprehensive, and does not require expensive external test equipment (ATE). We have successfully implemented this BIST approach for delay-fault testi...
