A tri-show event that included the Battery Show North America, Electric & Hybrid vehicle technology Expo, and the Critical Power expo concluded last week in Novi, Mich. and hosted numerous technical presentations and displays of interesting technology. Here are some of the more noteworthy developments we noticed on the exhibition floor. NEXT PAGE: All hail […]
20 mA current loops, Part 2: Advanced features
Part 1 of this FAQ looked at the basics of the 20-mA current loop, why it is still used extensively, and its primary attributes. In this part, we’ll look at how the analog current loop is used for digitized signals and at self-powered loops – two developments which have extended its life and viability. Q: […]
New processor platform for smartwatches extends battery life
Qualcomm Technologies, Inc. launched the next generation Qualcomm Snapdragon Wear 3100 Platform for smartwatches. The platform is based on a new ultra-low power system architecture designed to deliver a rich interactive mode, new personalized experiences, and extended battery life. The official launch, at an event in San Francisco, was supported by Google, who discussed the […]
20-mA current loops, Part 1: Basic functions
You’ve been given an “easy” assignment: get the low-rate data from a temperature sensor to a control computer located 100 feet (30 m) away, in an industrial setting. After much investigation and assessment, you choose a widely used standard called the 20-mA loop, which has been in use for over 50 years, rather than Wi-Fi, […]
SSDs: secure erase or sanitize?
When you’re done with a data storage drive, it’s nice to make sure that all of the data is scrubbed from it. A drive that’s returned, repurposed, or discarded can have personal or confidential data on it. Discarded drives have been found with everything from financial and medical data, email, and even pornography on them. […]
Working with the PicoScope PC-based oscilloscope
A PC-based oscilloscope, or USB oscilloscope as it is also known, has a lot going for it. For one thing, it costs substantially less than a bench model with equivalent specifications, given that most users already own the major component. The PC or Mac provides the processing and display parts of the equation. (The computer, […]
Additive manufacturing: To do or not to DIY 3D printing
As 3D printers become more ubiquitous and less costly, the idea of DIY 3D printing or additive manufacturing — for product development, prototyping and manufacturing — becomes increasingly attractive. Images and videos abound of shiny and sophisticated 21st-century industrial machinery creating a solid product from thin layers upon thin layers of material in succession bringing […]
Working with waveforms in mixed-domain oscilloscopes
Waveform generators generally contain a library of common waveforms, which can be individually accessed and displayed by running a BNC cable to an active analog channel input in an oscilloscope. Most oscilloscopes have, available as an option, an internal arbitrary function generator (AFG), which permits the user to create an endless variety of waveforms and […]
