Transmission Electron Microscopy for Imaging of Biological Molecules
Transmission Electron Microscopy for Imaging of Biological Molecules Customer Case The customer is improving their customized Transmission Electron Microscope (TEM) that is optimized for imaging unstained biological molecules with minimal radiation damage. Diffraction-limited resolution of 0.25 nm is routinely obtained with a cold field-emission electron-gun operating at 40 keV. The sample is maintained at about 123 K (i.e. -150°C), both to eliminate contamination and to reduce mass-loss. The scan raster is 512 x 512 points with a dwell time of 30 microseconds per pixel (over 8.5 seconds per raster-scan). For most mass measurements, the pixels are separated by 1 [...]
Treadmill Power Glitch Monitoring
Treadmill Power Glitch Monitoring Customer Case A customer develops gym equipment such as treadmills. The requirement is for an inexpensive way to monitor voltage signals for long periods of time. The treadmills are controlled by microprocessors that drive the LED displays. The customer has observed that some units intermittently fail during testing, a condition known as a "glitch" or a "brown-out". A glitch can have many causes, one of which is a weak power supply. The customer needs to capture certain key signals when a glitch occurs. At that stage, based on the captured data, it can be determined [...]
Measurements Using Capacitive Sensors
Precise Measurements Using Capacitive Sensors Capacitive sensors can be divided into two categories based upon their performance and intended use. High resolution sensors are typically used in displacement and position monitoring applications where high accuracy, stability and low temperature drift are required. Quite frequently these sensors are used in process monitoring and closed-loop feedback control systems. Proximity type capacitive sensors are much less expensive and are typically used to detect the presence of a part or used in counting applications. Applications Position Sensing General positioning is probably the most [...]

White Paper: Three Vibration/Balancing Solutions for the Aviation Industry
Three Vibration/Balancing Solutions for the Aviation Industry Audience Turbine engine balancing for aviation professionals: - AMTs - Test Cell Engineers and Managers - Engine Flight Line Technicians - Engine Vibration Specialists Description Throughout the aviation industry, jet engine vibration is an everyday concern. Maintenance, repair, and overhaul crews worldwide are tasked with monitoring aircraft engine vibration to ensure flight safety and efficient service. Gone unchecked, jet engine vibration can be the catalyst for any number of problems, from minor annoyances such as cabin noise to undue parts wear. In the most severe cases, an out-of-balance turbine could [...]
