The marriage of convenience (some might say a temporary truce) between Feds and hackers – organized at the annual DEF CON conference – simply couldn’t survive in our current geopolitical environment. And the hackers want a divorce – the Feds will not be at DEF CON this year.
I'm interested in time and frequency. In order to generate accurate time ticks you need accurate clocks. Cell phones are a major user of accurate clocks. And vibrating quartz has been the standard for such clocks for a very long time. But there is a new kid on the block. Micro-Electro-Mechanical Systems (MEMS) oscillators made by Silicon Labs.
One of the challenges of working with integrated circuits is as designers try to make ICs faster, the transistors become smaller and can’t handle as much voltage and the amount of variation grows. Plus, a single fault in the IC could mean a useless chip, bringing projects and products to sudden jarring halt.
We now know - due to some intrepid leakers - that Big Brother is watching just about everything that can be electronically monitored. It is commonly accepted that this watching is a result of the Patriot Act. But there is something that predates the Patriot Act that is the real enabler - Secret courts.
Though we might not agree on the reasons why there is such a discrepancy between the percentage of women in the population and the percent who become engineers, we can all agree it’s not a good thing. At the end of the day whether it’s an issue of nature, nurture or a combination of the two, that can’t be the end of the discussion. The conversation needs to evolve to a place focused on addressing the issue.
There’s no end in sight to the tug of war between proponents of the connected car and those who want to curtail use of electronic devices for fear of distracted driving. The latest salvo from the safety side came in from the AAA Foundation for Traffic Safety, which in June released a study....
The Big Bang Theory — a television show that features four male scientists and engineers and an attractive blond waitress — is one of the top shows on TV. But a recent study has raised an interesting question: Does this show’s — and others like it's — depiction of what scientists and engineers look like actively discourage women from pursuing STEM degrees? According to the study, it might.
TE Connectivity (TE) launched a line of M.2 next-generation form factor (NGFF) connectors, which are designed using the new interface standard for a smaller form factor in both size and volume. Engineered for a wide range of applications, including SSDs (solid state drives) and wireless cards of all types for use in notebooks, ultraportable devices, tablets, desktops and servers, TE’s M.2 (NGFF) products meet both current and future market needs for slim solutions
Do red-light traffic cameras reduce accidents? Save lives? Are they a boon to resource-strapped law enforcement agencies? A boondoggle? An invasion of privacy? With government surveillance – and the citizenry’s awareness thereof – at a fever pitch, this issue will only become more relevant ... and divisive.
In the early days of white-emitting LEDs, the available chip packaging materials were ones developed decades earlier for use with red- and green-emitting devices. Unfortunately, when using those materials for blue-based white LEDs (blue LED + phosphors), unexpected problems arose.
Standard incandescent lamps convert almost all the power they consume into radiation (basically, heat). Unfortunately, only about 5% of this emission is in the visible spectrum, making them very inefficient light sources. On the other hand, since almost all the power is radiated away, there is little need for thermal management.
I’m standing in the taxi queue at Chicago’s O’Hare airport, having to squint ahead to gauge my wait. The cause of my discomfort: a horrible, blue-LED array-based outdoor luminaire ahead of me and above, spilling light in all directions and casting a putrid smear of yellow-green color against a nearby wall of the terminal, and directly into my eyes.
When it comes to the racing world, electronics suppliers and distributors are often behind the scenes—or under the hood, as it were—rock stars. Sure, they’re the reason the engine runs or making sure the driver and crew are safe, but they’re very rarely front and center in the racing world. Unless, of course, you’re talking about Mouser’s sponsorship of Indy car driver Tony Kanaan ... then it’s all about being in front (literally.)
As a novelist, Daniel Suarez spins dystopian tales of the future. But on the TEDGlobal stage, he talks us through a real-life scenario we all need to know more about: the rise of autonomous robotic weapons of war. Advanced drones, automated weapons and AI-powered intelligence-gathering tools, he suggests, could take the decision to make war out of the hands of humans.
I am a fan of not sending soldiers into battle, but I understand that wars still need to be fought (sometimes). Drones are a solution to that conundrum, firepower without the high risk for lives (on our side at least). Putting any ethics aside about drones killing civilians and the lack of a weight of responsibility...
House fires are a serious, deadly problem. Death from fires and burns are the third leading cause of fatal home injury, according to the CDC. Every 169 minutes, someone dies in a fire and every 30 minutes, someone is injured.
If we want our opinions to be easily influenced by something, watching movies is the solution. Movies are a form of art that is globally used for entertainment purposes. Science fiction films that exhibit unusual and odd actions and gadgets are the ones doing big businesses on the box office.
I have been in the LED business for almost twenty years, and each year I hear a comment along the lines of “LEDs are a commodity product”. What’s the definition of a commodity product? It’s one that is very cheap, undifferentiated, anybody can make it, and margins are low.
Tripp Lite has introduced PDU Plug-lock Inserts, a simple-to-use solution for preventing accidental disconnection of C20 and C14 plugs. IEC plugs are frequently loose-fitting and can be accidentally disconnected by even the slightest nudge or vibration, a likely event during routine network maintenance.
A few weeks ago I mentioned that an eminently qualified historian of technology has written a biography of Nikola Tesla (1856-1943), the inventor of the eponymous Tesla coil, the induction motor, and numerous other ingenious contraptions. While Tesla has been the subject of numerous popular biographies and even a film or two...
Pickering Interfaces has expanded its range of 2Amp 1-Pole matrices with releases that include the highest density solutions available in PXI large matrix (BRIC) format. The 40-596, 40-597, and 40-598 are all BRIC 1-pole matrices with 2Amp current rating, up to 60W hot switch power and 100VDC/70VAC voltage rating – depending on the configuration....
“Ten bucks for a light bulb?!”, exclaims my daughter in response to my estimate of the ‘tipping point’ price for LED-based lighting products for the residential consumer. She, like many consumers, has yet to internalize that the real cost of ‘inexpensive’ conventional light bulbs is energy consumption, and that LEDs pay back on this aspect right away.
Any time a new, disruptive technology enters the public sphere, concern is raised about almost every conceivable aspect. This is especially the case for lighting wherein each and every one of us has a base of experience and, likely, some opinions. While it is certainly prudent to scrutinize any new technology from a health and use perspective...
For most people, thinking about space isn’t a daily activity. Sure, there are random bursts of excitement like the Mars Rover landing or Canadian superstar astronaut Chris Hadfield and of course there are people—both amateur and professional—who make space their life, but in general, it’s not something we think about too much.
New jumpers provide horizontal and vertical potential commoning for WAGO Corporation's Double-Deck TOPJOB S 2000 Series and X-COM S MINI 2020 Series DIN-rail terminal blocks. Users can vertically common both levels of a double-deck terminal block or multiply potential over several adjacent DIN-rail
