Acoustic Engineering with Stimulus Response System
Acoustic Engineering with Stimulus Response System Customer Case The performance of music without electrical amplification requires precise acoustic engineering of its venues. A customer advises concerning large-scale renovations to existing cathedrals, concert halls and opera houses. Renovations may include decoupling the structure from its surroundings to minimize outside noise and redesigning the interior in order to optimize echo patterns. Buildings are acoustically characterized with precision sound equipment. A sound Stimulus, S(t), is generated by a loudspeaker and the Response, R(t) is received by a microphone, where t is time. Usually, the loudspeaker and microphone are positioned at the musician [...]

White Paper: High Performance Test Equipment Assures LED Lighting Products Comply with Industry Standards
Introduction Manufacturers and users of LED lighting applications need to be assured that their products will be qualified according to a multitude of reliability and efficiency standards. In addition to voluntary initiatives and programs like EnergyStar, mandatory standards and specifications for the lighting industry must be kept in mind during project development, including the latest IES LM-79-19 and the ANSI C82.16 documents. This article gives an overview of relevant lighting standards and specifications for LED lighting products. It also describes the features of Vitrek’s test equipment, including the PA900 power analyzer — featuring built-in lighting specifications — as [...]
The Benefits of Manual, Semi-Automated, and Fully-Automated Systems for Semiconductor Wafer Inspection and Metrology
This is the third of three articles in Semiconductor Wafer Measurement for Increased Profitability. The first article in this series explains why disc geometry matters. The second article examines the cost of failing to inspect semiconductor wafers. Fully automated systems that can load, scan, and unload wafers are fast, convenient, and efficient at high volumes. They’re useful for checking every wafer in every batch, but these systems are expensive. Semi-automated and manual systems cost significantly less and are generally used for lower volumes; however, they’re also easy-to-use and can make fast, accurate measurements that support production flow. Semi-automated and [...]
Why Disc Geometry Matters In Wafer Production
This is the first of three articles in Semiconductor Wafer Measurement for Increased Profitability. The second article examines the cost of failing to inspect semiconductor wafers. The third article describes the benefits of using semi-automated, fully-automated, and manual systems for wafer metrology and inspection. Semiconductor wafers are cut from cylindrical silicon crystals, or ingots. The flatness of these disc-shaped wafers is controlled to tight tolerances to ensure that the entire wafer surface is suitable for integrated circuit (IC) production. If disc geometry is out-of-spec after cutting, it may be possible to reprocess the wafer. Cutting is only the first [...]

MTI uses [...]
Aircraft Vibration Analysis and Measurement Techniques
Aircraft engine vibration is a critical indicator of engine health and overall flight safety. While some level of vibration in aircraft is expected during normal operations, excessive or abnormal vibrations often signal underlying mechanical issues that demand immediate attention. With modern jet engines becoming more complex, real-time vibration monitoring and precise balancing tools are essential for both aircraft maintenance teams and aviation diagnostics specialists. Aircraft vibration measurement tools detect and quantify these issues, enabling maintenance teams to take corrective actions before minor imbalances escalate into major faults. Types of Aircraft Vibrations There are two main categories of aircraft vibrations: [...]
How Capacitive Measurement Can Help Reduce Packaging Waste
Product packaging is often made of lightweight polymeric foams or plastic sheets and films. These materials are relatively inexpensive, but manufacturers still want to minimize waste and maximize yields. Across high volumes of low-cost materials, even a small per-unit savings can become significant, especially as the price of petroleum – a key ingredient in many polymers – continues to rise. For companies with environmental sustainability efforts, there are other important considerations as well. The excessive use of packaging materials can contribute to environmental pollution, especially with polymers that are slow to degrade. Yet, materials such as plastic sheets and [...]
