YouTube has several videos featuring really bad designs for fast phone chargers. YouTubers doing these videos often point to problems such as transformers with chintzy insulation, line capacitors that lack the correct safety rating, and even chargers with plastic cases that heat up so much that they actually melt when there’s a heavy load. Fortunately, […]
FAQ
Are gold- or silver-plated connectors or contacts right for my application?
Learn the proper electrodeposition for contacts and connectors to ensure reliability in your electrical devices. Contributed by Luke Copp • Sales & Marketing Associate for Advanced Plating Technologies Modern manufacturing relies on critical connections made via strong electroplating, as more and more devices are connected to provide instant access to information and data. However, any electrical […]
Satellites launch 4G/5G service to remote regions
The first two O3b mPOWER satellites operated by SES have launched. Once fully deployed, 11 satellites will significantly improve throughput and latency to areas all over the world. EE World was there for a firsthand video view of the launch.
What is dosimetry? Pt 1
In the broadest sense, dosimetry is done to measure and prevent or at least identify problems from significant or long-term exposure to harmful situations. More specifically, dosimetry refers to the study, measurement, method of measurement or instrument of measurement of radiation dose. Dosimetry often involves wearing a personnel badge, a dosimeter, that measures and monitors […]
How AI spurs efficient wireless systems design
AI techniques can overcome nonlinear problems by extracting patterns automatically and efficiently.
How to run video games on an oscilloscope
Spend enough time on YouTube and you’ll uncover numerous videos showing some kind of video game being played on an oscilloscope. The most popular game choices for these videos seem to be the old Doom and Quake games and Pong, the first real video game released in 1972. Perhaps the main reason for Doom’s popularity […]
Don’t let system complexity discourage basic troubleshooting
A somewhat justified concern about damaging a complex system can also intimidate you from a basic investigation into a system problem. OK, I admit it: I avoided checking for an obvious problem due to my fear of making things worse in a high-risk situation. Fortunately, the only cost, in this case, was to my pride. […]
What are digital twins, and where are they on the “hype cycle”?: Part 2
Digital twins are getting lots of deserved attention, but are they the cure-all for whatever simulation issues you have? Although digital twins are undoubtedly valuable tools along with basic simulation, modeling, HITL, and others, the associated all-good/no drawbacks promotion concerns me. When a tool, product, or other development gets a lot of “pumping up” to […]
What are digital twins, and where are they on the “hype cycle”?: part 1
Digital twins are getting lots of deserved attention, but are they the cure-all for whatever simulation issues you have? Lately, I’m seeing what are called “digital twins” cited everywhere. What is a digital twin? In addition to having that very catchy name, it is a highly advanced model of the system which can be used […]
What are next generation bio sensing techniques? Pt 2
Part 1 of this blog explored research into localized surface plasmon resonance (LSPR) sensors. This part discusses a surface plasmon resonance/surface-enhanced Raman scattering (SPR/SERS) dual-mode plasmonic biosensor and two other sensing techniques. The SPR/SERS biosensor based on catalytic hairpin assembly (CHA)-induced Au nanoparticle (AuNP) network was proposed for highly sensitive and reliable detection of a […]
