    Being proved right isn't always fun. Just weeks after my warning in the March issue that our modern high-tech cars are tracking us and sharing data with manufacturers, cops, and parties unknown, came a report of soaring auto insurance premiums because of snitching vehicles. The consequences get worse from there. Fortunately, there are ways to keep your snoopy ride from contacting the mothership. Your Driving History May Be Transmitted and Stored "Car companies are collecting information directly from internet-connected vehicles for use by the insurance industry," Kashmir Hill reported this month for The New York Times. "Sometimes this is happening...

    Hidden cameras are being found in hotel rooms, house rentals, cruise ships, and even airplane bathrooms, leaving many travelers to wonder: “Could a hidden camera be watching me?” Spycams, as they’re called, are getting smaller, harder to find and easier to buy. From alarm clocks to air fresheners, water bottles and toothbrush holders, cameras come embedded in common household items that seamlessly blend with home decor. They can be purchased in shops or online, and through retailers like Amazon and Walmart. And rather than having to retrieve the camera to obtain the recording, owners can stream live images straight to...

    I've built power supplies using full wave rectifiers in the past, and a couple circuits with single diode half wave rectification for non-critical supplies, but in all cases the power requirements were low and the diodes I had on hand several times overrated for the current and voltage / power involved.This time though, I want to add a half power function to a 1500 watt 120 volt quartz heater. (Over-simplification - see below comments. But ~half of the 1500 watts is the design target.)*So... I know a diode in series with the quartz element and no power supply capacitor** will...
  • Study finds common complication of pacemakers four times higher than previously thought

    05/27/2023 5:31:03 AM PDT · by ConservativeMind · 12 replies
    About 3 million Americans live with cardiovascular pacemakers. But over time, scar tissue or blood clots can form around the leads, or wires, that carry the electrical impulses from the pacemaker to the heart. Scar tissue or clots may hinder the flow of blood, potentially resulting in swollen extremities or pain. However, the incidence and clinical impact of such lead-related venous obstruction, or LRVO, among patients with pacemaker devices is not well characterized. Physician-researchers found that the incidence of symptomatic LRVO among patients implanted with cardiovascular implantable electronic devices to be four times higher than previously reported—with only a minority...

    The germanium-tin processor was fabricated at the Helmholtz Nano Facility, the Helmholtz Association's central technology platform for the manufacturing of nanostructures and circuits. Credit: Forschungszentrum Juelich Scientists at Forschungszentrum Jülich have fabricated a new type of transistor from a germanium–tin alloy that has several advantages over conventional switching elements. Charge carriers can move faster in the material than in silicon or germanium, which enables lower voltages in operation. The transistor thus appears to be a promising candidate for future low-power, high-performance chips, and possibly also for the development of future of quantum computers. Over the past 70 years, the number...

    The week of last Thanksgiving, Michael Larkin, a business owner in Hamilton, Ohio, picked up his phone and answered a call. It was the local police, and they wanted footage from Larkin’s front door camera. Larkin had a Ring video doorbell, one of the more than 10 million Americans with the Amazon-owned product installed at their front doors. His doorbell was among 21 Ring cameras in and around his home and business, picking up footage of Larkin, neighbors, customers and anyone else near his house. The police said they were conducting a drug-related investigation on a neighbor, and they wanted...

    Australia will remove Chinese-made surveillance cameras from defence sites over national security fears. It comes after an audit found 900 pieces of surveillance equipment built by companies Hikvision and Dahua on government estates. The audit of Australian government sites found the cameras and security gear were located on more than 200 buildings, in almost every department - including the foreign affairs and attorney general's departments. At least one unit was also found in the defence department, but the total number at defence sites is unknown. Defence Minister and Deputy Prime Minister Richard Marles on Thursday said the government would find...

    The beginning of the end of Europe’s dependency on China for precious rare earth materials may lie buried deep under the rugged reaches of northern Sweden, well above the Arctic Circle. Sweden’s iron-ore miner LKAB said Thursday it has identified "significant deposits" in Lapland of rare earth elements that are essential for the manufacture of smartphones, electric vehicles and wind turbines. The government-owned company that mines iron ore at Kiruna, almost 1,000 kilometers north of Stockholm, said there are more than 1 million tons of rare earth oxides....

    The electronic strike zone will be used in all 30 Class AAA parks in 2023, sources told ESPN, seemingly another significant step toward the implementation of the technology at the big-league level in the near future. The Automatic Balls and Strikes system, commonly referred to as ABS, will be deployed in two different ways. Half of the Class AAA games will be played with all of the calls determined by an electronic strike zone, and the other half played with an ABS challenge system similar to that used in professional tennis.

    The "mark of the beast" as described in the New Testament's Book of Revelation can be interpreted as a mark that will regulate trade. But even the Book of Revelation didn't include a pill you could swallow that would allow the government to see if you have complied with your orders. This is beyond sinister. A clip of Pfizer CEO Albert Bourla describing his company's new technology to a group of elites at the 2018 World Economic Forum in Davos, Switzerland, has gone viral on social media over the past few days.

    A team of physicists at CU Boulder has solved the mystery behind a perplexing phenomenon in the nano realm: why some ultra-small heat sources cool down faster if you pack them closer together. The findings, which will publish this week in the journal Proceedings of the National Academy of Sciences (PNAS), could one day help the tech industry design speedier electronic devices that overheat less. “Often heat is a challenging consideration in designing electronics. You build a device then discover that it’s heating up faster than desired,” said study co-author Joshua Knobloch, postdoctoral research associate at JILA, a joint research...

    The great computer chip shortage of 2021 will likely get worse before it gets better. This conclusion was reached following brief study and anecdotal review. Moreover, while COVID lockdowns may have initially triggered the shortage, several decades of shortsighted decisions and simmering geopolitical tensions make it much more than a matter of fixing a few broken links in the supply chain. Here’s why… The world’s top two leading chip companies are Taiwan’s TSMC and South Korea’s Samsung Electronics. These two Asian firms, combined, control more than 70 percent of the semiconductor manufacturing market. The U.S., which was once a leader,...
