What is normal blood pressure?

January 15, 2024 By Randy Frank

If you answered 120 over 80 mmHg, you are using criteria that is over 20 years old. As reported in a 2003 article, revised guidelines categorized normal blood pressure as <120/80 mmHg. Since the measurements are meant to lower the risks from not recognizing what is often called the silent killer – high blood pressure […]

How will NHTSA’s AEB mandate impact sensing?

December 21, 2023 By Randy Frank

In 2019, the U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) published a draft pedestrian automatic emergency braking (PAEB) test procedure. When, the results of testing conducted in 2022 on 12 light vehicles were published in 2023 (2022 Light Vehicle Pedestrian Automatic Emergency Braking Test Summary, March 2023), one conclusion was: No vehicles […]

How sensors help you play ball: part 3

December 15, 2023 By Randy Frank

Sensing in the 2022 FIFA World Cup soccer ball consists of a 6-axis motion sensor, a 3-axis magnetometer, a pressure sensor (in one version), and ultra-wideband (UWB) technology. The 0 to 2 bar (0 to 29 pounds per square inch (psi)) pressure sensor with 0.025 (0.36 psi) resolution can confirm that the ball is within […]

How sensors help you play ball: part 2

December 11, 2023 By Randy Frank

A FIFA-compliant match ball from Adidas has a TDK InvenSense 6-axis MotionTracking device and other electronics mounted in the center of the ball. As shown in Figure 1, the Adidas patented suspension system stabilizes the electronics module. Instead of having the sensing/communication module mounted on the surface of the ball near the inflator valve, the […]

How sensors help you play ball: part 1

December 6, 2023 By Randy Frank

In addition to the respect and pride of accomplishment that winning in any sport provides, if it’s done at the professional level, the monetary rewards of winning can be great as well. In fact, exceptional performance can create a lasting legacy for a player, a team, and a coach. This gives coaches, trainers, and the […]

What’s the difference between sensors used in underwater, flying, and creeping robots or drones? part 4

November 20, 2023 By Randy Frank

Multimodal robots that can fly and walk or crawl have been the basis of research for many years. In 2016, researchers at the University of Pennsylvania’s GRASP Laboratory reported the development of the Picobug with multimodal characteristics of climbing, jumping, and gliding, or even flying and swimming. With a research paper detailing many executed and […]

What’s the difference between sensors used in underwater, flying, and creeping robots or drones? part 3

November 17, 2023 By Randy Frank

The abilities of robots continue to advance with highly capable products performing a variety of tasks, looking almost humanlike as they speak, and even garnering appearances in movies.  Perhaps less attractive but equally or even more useful, creeping or crawling robots bring drones down to earth and, in fact, inside the earth. Unlike the micro […]

What’s the difference between sensors used in underwater, flying, and creeping robots or drones? part 2

November 8, 2023 By Randy Frank

While flying drones are common in military, consumer, and even commercial applications, there are a few intriguing, much smaller and less familiar flying drones in development. Called a micro air vehicle (MAV), or micro aerial vehicle, this class of very small flying drones have applications in agriculture, disaster relief, by both military and enterprise users, […]

What’s the difference between sensors used in underwater, flying, and creeping robots or drones? part 1

October 31, 2023 By Randy Frank

Obviously, different design requirements exist depending on the targeted applications, but autonomous or remotely piloted drones also dictate different criteria. One of the more unique underwater applications involved undersea (in the ice) measurements in Antarctica. The intent of the expedition was to gather sufficient, highly accurate information to improve modeling of ice shelf melting and […]
