Electronics Subracks: Requirements, Selection Criteria And Options For Adaptation

When selecting an electronics subrack, it is important to consider several factors, including application requirements and environmental conditions. Flexible product platforms, such as modular subracks, enable diverse configurations for various dimensions, static and dynamic loading levels such as shock and vibration resistance, electromagnetic interference shielding and individual internal mounting options.

R&S® SMB100A, NRP, FSW-K6, ZVL Radar Educational Videos

Welcome to our short video tutorials on how to test radars using Rohde & Schwarz test equipment. Access to most information about radar tests is pretty restricted, as many radar applications are military or secretive industrial research. To show some basic radar tests we have created radar demo tools, which functions at a frequency of 2.45 GHz, which is in the unlicensed 2.4 GHz Industrial, Scientific and Medical (ISM) band. So tests can be performed in unshielded rooms. The frequencies are also used by radar operating in the ITU "S"-band from 2.3 to 2.5 GHz for air traffic control, weather and marine radar.

Will Most Doctors Adopt Wearable Computing Like Google Glass?

Emergency room clinicians at the Beth Israel Deaconess Medical Center in Boston recently tried out the wearable Google Glass eyeglasses. With Google Glass, the doctors could communicate and examine patients while simultaneously reading their charts. By using Glass to access information, doctors could remain with a patient and did not need a tablet to search through relevant medical documents and files.

Fundamentals of Vector Network Analysis Primer

One of the most common measuring tasks in RF engineering involves analysis of circuits (networks). A network analyzer is an instrument that is designed to handle this job with great precision and efficiency. Circuits that can be analyzed using network analyzers range from simple devices such as filters and amplifiers to complex modules used in communications satellites.

Engineers Build 3D Acoustic Cloaking Device

Using little more than a few perforated sheets of plastic and a staggering amount of number crunching, Duke engineers have demonstrated a three-dimensional acoustic cloak. The new device reroutes sound waves to create the impression that both the cloak and anything beneath it are not there.The acoustic cloaking device works in all three dimensions, no matter which direction the sound is coming from or where the observer is located, and holds potential for future applications such as sonar avoidance and architectural acoustics.The materials manipulating the behavior of sound waves are simply plastic and air. Once constructed, the device looks like several plastic plates with a repeating pattern of holes poked through them. The plates are stacked on top of one another to form a sort of pyramid.The cloak must alter the waves’ trajectory to match what they would look like had they had reflected off a flat surface. Because the sound is not reaching the surface beneath, it is traveling a shorter distance and its speed must be slowed to compensate.To test the cloaking device, researchers covered a small sphere with the cloak and “pinged” it with short bursts of sound from various angles. Using a microphone, they mapped how the waves responded and produced videos of them traveling through the air.SourceLearn about an Acoustic Liner for Turbomachinery Applications.

Coming Soon - Innovative Antimicrobial Resistant Polymers for Medical Devices

Secondary infections found in hospital environments are becoming an increasingly significant concern for patients, hospital administrators, and staff. Patient care can be negatively affected when a secondary infection caused by a variety of microorganisms commonly found in healthcare environments leads to health issues for a patient. With insurance companies no longer covering the expense for secondary infections, the cost to hospitals for the infections can lead to a negative return on their bottom line.
