Mathematics is the language we use to understand and communicate our knowledge about electrical relationships. It is easy to get overwhelmed by some of the complexity involved. The best approach is to begin at the most fundamental level and take it from there. Consider the realm of sinusoidal signals. First, a definition: A sinusoidal signal […]

Tiny recorders let crash test dummies take one for the Gipper
The University of Alabama at Birmingham’s (UAB) Department of Mechanical Engineering is developing new testing methodologies using crash test dummies to improve helmet testing and ultimately reduce concussions and traumatic brain injuries (TBI). In that regard, they are putting sensors and recorders inside crash test dummy heads to get biofidelic impact data. Miniature DTSSLICE NANO […]
Basics of working with I2C buses
Back in olden days, parallel buses were used to link electronic building blocks. Today serial buses have largely replaced them. There are numerous components for many applications that have standard serial interfaces, and this trend makes serial technology a good choice for design engineers. Because there are fewer signal lines, serial bus electronics take up […]
Multi-gigabit serial protocols demystified
Chris Nunn, National Instruments Corp. High-speed serial is a growing technology aimed at reducing device footprint and boosting data communication rates. We have seen a drastic change in digital communication buses shifting from parallel to serial formats starting in the early 2000s. The transition from parallel buses to high-speed serial buses has led to many […]
Wideband transceiver optimized for tests of 802.11ad devices
Keysight Technologies, Inc. (NYSE: KEYS) today announced the volume launch of their solution for testing 802.11ad devices. The flexible and compact E7760A wideband transceiver is an integrated test solution that supports the IEEE 802.11ad wireless standard. The solution was introduced at Mobile World Congress in Barcelona earlier this year. “Our customers are looking for millimeter […]
Dummies from NASA instrumented
with data acquisition systems
Engineers at NASA’s Langley Research Center in Hampton, Va., will conduct nine water-impact drop tests to evaluate the safety of the splash down when the Orion spacecraft returns from deep-space missions and touches down on Earth. Onboard will be two test dummies wired up to Diversified Technical Systems (DTS) data acquisition systems. The DAS data […]
New software released for Renishaw’s Boretrak borehole monitoring systems
Renishaw’s Boretrak Viewer is the new version of stand-alone software for use with the company’s Cabled Boretrak and Rodded Boretrak borehole deviation measurement systems. These measurement probes are designed to support a variety of drilling operations by providing vital borehole deviation analysis required to make fast and informed decisions. By using Boretrak to survey drill holes, any […]
Space Vectors aide drive for optimal efficiency
by Johannes Teigelkötter, HBM Using space vectors in test equipment helps engineers get a clearer, more precise picture of three-phase motor electromagnetics. With the continuing emphasis on the use of renewable sources of energy, as opposed to the reliance on fossil fuels, advances in induction motor design are allowing for greater efficiencies in both consumer […]
