Basic passive microwave components have a vital role in RF/microwave system design. Despite the apparent simplicity of their functions, their performance is based on electromagnetic theory and Maxwell’s equations for insight into their operating principles and performance. Design for the demands of microwave signals is a very different situation than working at lower frequencies. Although […]
Inertial Measurement Units: The hidden key to Apollo success, now a MEMS device (Part 2)
Part 1 of this article looked at the classic, highly refined, mature gyroscope-based IMU used for the Apollo moon mission; this part looks at the very different technologies which have largely replaced it. Gyro-based IMU: obsolete, or not? Inertial navigation relies on a stable platform with an orientation which is fixed in space and maintains […]
What are MEMS microphone arrays?
Beamforming arrays let designers create directional microphones using MEMS devices. With the right signal processing algorithms, these can enhance the user experience delivered by many types of audio equipment. An array can be simple, comprising as few as two microphones, and can be arranged in various configurations depending on the expected location of the preferred […]
Understanding low-power checks and how to use them
by Aijaz Fatima, Mentor, a Siemens business We live in a shrinking world, and like so much else, the size of ICs is shrinking too. The small size of an IC has many advantages, but it increases the power density of the IC, which leads to many concerns. An IC with a high power density […]
Exploring connectors for the industrial IoT
Industrial IoT (IIoT), or Industry 4.0, is revolutionizing the way factories, suppliers and customers share their digital knowledge. From process control and automotive assembly, to robotics and the food and beverage industry, the concept behind Industry 4.0 touches all industries. However, the benefits of IIoT are not available at the flick of a switch. To […]
Hot topic: How to measure plasma in a fusion reactor
The International Thermonuclear Experimental Reactor (ITER) tokamak is an experimental machine designed to harness the energy of fusion. ITER will be the world’s largest tokamak, with a plasma radius of 6.2 m and a plasma volume of 840 m³. The heart of a tokamak is its doughnut-shaped vacuum chamber. Here, under the influence of extreme […]
How can you have touchless touch sensing?
At Sensors Expo 2019 in San Jose, CA, Håkan Persson, CEO of Neonode Inc., demonstrates touchless sensing using his company’s vertical-cavity surface-emitting laser (VCSEL) technology. Neonode’s zForce® (zero force) patented optical sensing technology uses infrared light, invisible to the human eye to provide a holographic touch screen, essentially making air touchable. The holographic design consists […]
Inertial Measurement Units: The hidden key to Apollo success, now a MEMS device (Part 1)
Transforming the gyroscope from a child’s toy to a precise guidance system for the Apollo moon landings demanded the ultimate in analytical, engineering, and manufacturing effort: now, MEMS-based units have largely replaced these gyro-based systems. With the 50th anniversary of the Apollo manned lunar landing on July 16, 1969, 9:32 AM GMT-4, there have been […]
How can lasers be used for touch sensing?
At Sensors Expo 2019 in San Jose, CA, Bengt Edlund, the Vice President of Distribution & Partner Sales for Neonode Inc. demonstrates the touch sensing capabilities that Neonode’s ZForce AIR sensor module can provide to non-glass surfaces. The laser light based touch sensor provides a unique approach to increasingly common touch sensing applications and enables […]
How to tackle the tough stuff around IoT security – Part 2
In part 1 of this interview with Jason Soroko, CTO of IoT for Sectigo, and Alan Grau, former president and owner of Icon Labs and now VP of IoT/Embedded solutions at Sectigo, we learned how the acquisition of Icon Labs by Sectigo was a strategic move to being able to offer end-to-end and purpose-built IoT […]
