Up close and personal with the Shuttle Independence
Steve Taranovich 12/20/2018 Post a comment
While in Houston recently, I visited the Space Center Houston and toured the 80-ton shuttle replica Independence, mounted atop the historic and original NASA 905 159-ton shuttle carrier aircraft (SCA), which was the first of the SCAs.
5G: Where is it and where is it going?
Martin Rowe 12/19/2018 1 comment
Despite the oncoming hype, 5G has a considerable way to go given that deployment is just beginning. We still need much of systems to get into full production. Then, businesses and consumers will have to buy the products.
The e-car: Electronics technology applied to sustainable mobility, Part 9
Busy Blogger 12/18/2018 1 comment
This blog series is focused on the wealth of possibilities offered by an interaction between the car’s driver and the smart car powered by means of smart electronic systems that are able to detect the physiological status of the driver and take preventive and corrective actions as well to preserve the safety and the comfort of the occupants of the e-car.
The current drive current sense circuit
Jerry Steele 12/5/2018 Post a comment
The op amp-based current sensing circuit described here is not new, it has been around for some time, but with very little discussion of the circuit itself. Somewhere along the line it was informally given the name: "Current Drive" circuit, so we'll call it that for now.
Battery-free power for wireless switches
Troy Davis 12/2/2018 Post a comment
EnOcean has enabled millions of wireless light switches that do not contain batteries and has now introduced the “Battery-free by EnOcean” seal to highlight the self-powered switches’ benefits at a glance.
This article explains how the latest-generation SiC FETs are ideally suited to new inverter designs with lower losses than IGBTs and proven robustness against short circuits, even at high temperatures and under repetitive stress
There’s a further cool thing you can do with a spreadsheet that most SPICEs can’t. That’s to use the spreadsheet ‘solver’ functionality to adjust component values in the search for a better-fitting circuit – or even to find a set of component values for a circuit you can’t otherwise design.
Infineon MOSFETs have been embedded into PC boards by Schweizer Electronic AG
You now need to adjust component values to achieve some system goal, such as predefined frequency response or time behaviour, and there’s no closed method for working out those values.
