5G extends its scope beyond consumer only to many new vertical and enterprise markets. Thanks to its flexibility and improved performance, 5G opens the door to many industrial applications. When researchers and engineers began developing 5G in 2012, they began to look at use cases. The primary motivation for launching a new generation of wireless…

How to simplify automotive body motor controller designs with analog integration
by Arun Vemuri, General Manager, Automotive Body Electronics & Lighting at Texas Instruments When it comes to comfort and convenience in automotive, body motors are the key, whether it’s a perfectly positioned driver’s seat or the smooth, simple operation of doors, windows, and other vehicle parts. The purpose of these applications varies greatly, but one […]
How have drone sensors advanced?
Large Predator B drones, built by General Atomics Aeronautical Systems and first flown in 2001, are used by the military to perform multi-mission Intelligence, Surveillance and Reconnaissance (ISR) missions over land or sea. Sensing payloads in the MQ-9A Predator B remotely piloted aircraft (RPA), include: Multi-Spectral Targeting System Model B (MTS-B) Electro-optical/Infrared (EO/IR), Lynx multi-mode […]
What is IOTA?
IOTA is a cryptocurrency designed to add economics to the internet of machines. IOTA is quite different from thousands of other cryptocurrencies. Some key highlights of IOTA are as follows: IOTA is specifically designed for the Internet of Things. IOTA does not use blockchain technology; instead, it is based on Tangle technology. IOTA has theoretically […]
Analyzing different proximity sensor technologies
Utilized as a no-touch method to provide either precise distance measurement to an object or simple “there/not there” logic, proximity sensors span a wide range of technologies, each offering their own set of operating principles, advantages, and drawbacks. Some of the most commonly found technologies in portable or small embedded systems include ultrasonic, photoelectric, laser […]
AC/DC power supply testing and qualification – Virtual Roundtable, Part 1
Welcome to the first part of EEWorld’s two-part “virtual roundtable” discussion on ac/dc power supply testing and qualification. Today, we will be focused on various aspects of power supply efficiency, standby power, and static and dynamic output regulation testing. Our panelists are: Bill Griffith (BG), Power Products Marketing, Keysight Technologies: Johnnie Hancock (JH), Oscilloscope Product […]
Undersea optical-fiber cables do double-duty as seismic sensors, Part 2: Application
A research team has devised and tested a scheme based on advanced optical-physics principles, which uses active submarine optical-fiber data cables also to sense ocean-floor earthquakes and ocean-surface swells. The previous part of this article established the context for “piggybacking” seismic-sensing capabilities onto an existing undersea fiber-optic cable. This part looks in more detail at […]
Undersea optical-fiber cables do double-duty as seismic sensors, Part 1: Context
A research team has devised and tested a scheme based on advanced optical-physics principles which uses active submarine optical-fiber data cables to also sense ocean-floor earthquakes and ocean-surface swells. Sensing of physical parameters such as temperature, pressure, force, and velocity often brings a “split personality” analysis. On one hand, getting a reading of the basic […]
How to improve 5G coverage and capacity
The laws of physics work against RF engineers, forcing design tradeoffs in mmWave systems. Beam steering, frequency reuse, and greater spectral efficiency can help.
The difference between testing thyristors and triacs
The thyristor is a two- or three-pin device comprised of four alternating P- and N- layers. It is also known as a silicon-controlled rectifier and is often used in light dimmer switches, speed controllers for electric motors, and switch gear for high-voltage dc power transmission systems. The thyristor does not function as an amplifier–its output […]
