Test, Calibration, and Training Target for a Microwave Sensor

NASA’s Jet Propulsion Laboratory, Pasadena, California Human subjects are unsuitable for objective performance testing of victim detection radar because their heart and respiration rates are not controllable or repeatable. There are limitations on human targets from a safety standpoint as well. It is difficult to relate the ground truth to the measured data for a human target without needing additional equipment that must be attached to the human subject. Artificial targets using pneumatics do not provide sufficient fidelity of the radar return for development of identification algorithms.

Test it Like da Vinci

Timeless wisdom and new technologies are revolutionizing the world of testing, and bringing us from vision to finished product faster. Do you see product testing and checking as a necessary evil? Then take some time to change your mind. In the long process from vision to reality of a product, intelligent and efficient testing is indispensable. The latest metrological instruments help to begin developing a product when it only exists in our minds.

The Touch Screen Revolution

Touch screens are slowly but surely creeping into every aspect of our day-to-day lives. It’s not unlikely that you wake up to a cellphone alarm, adjust the room temperature on a thermostat, change the radio station in the car, and even start the washing machine using only a touch screen. A decade ago, we wouldn’t have used a touch screen for any of these tasks, but today it’s commonplace. To understand the impact of touch screens on test and measurement, you must first know the difference between resistive and capacitive touch screens, and the impact smartphones have had on touch screen implementations.

The Changing Face of Test

Many aspects of the test and measurement business are different from the way they were relatively few years ago. Perhaps the most obvious example is the people who are using test and measurement instrumentation. A recent industry study shows that 20 percent of electrical engineers now in the global workforce started their careers within the last decade.

Products of Tomorrow: January 2015

The technologies NASA develops don’t just blast off into space. They also improve our lives here on Earth. Life-saving search-and-rescue tools, implantable medical devices, advances in commercial aircraft safety, increased accuracy in weather forecasting, and the miniature cameras in our cellphones are just some of the examples of NASA-developed technology used in products today.

15 Questions to Ask About Circuit Protection for Wearable Electronics

Have you attended an electronics or design tradeshow lately? Have you visited a big-box retailer or browsed an online electronics vendor? If so, you’ve probably seen many examples of wearable technology, including smart glasses, clothing, wristwear, footwear, neckwear, and headbands. Wearable computing is one of the hottest consumer electronics trends on the market, with global sales expected to grow from $14 billion in 2014 to over $70 billion in 2024, according to IDTechEx.
