Introduction  Seems like a while since I looked at an insulation tester, this one has been around for a some time, but I have only just got to writing it up. This is number 8 in my ongoing quest to see if there is a small handheld insulation tester out there suitable for working on generator rotors. Previous testers reviewed are;   Keysight Insulation Multimeter Failure   Megger MIT420/2 Road Test   Chauvin Arnoux CA6526 Insulation Tester Review   Flir IM75 Insulation T ...
Researchers were able to reproduce a group coral in two days for the first time in a lab setting. Image - Coral spawning in a lab. (image credit: The Florida Aquarium)   Things are looking grim for America’s Great Barrier Reef. The third-largest coral reef in the world is on the verge of extinction, but a new scientific breakthrough may help save the reef. Researchers at the Florida Aquarium in Tampa Bay have successfully reproduced a group of coral two days in a row for the first ti ...
Engineers at MIT have created a magnetically controlled threadlike robot that glides through the narrow pathways, such as the labyrinthine vasculature of the human brain. Their research is published in journal Science Robotics.   The robotic thread (in black) can be steered around blood vessels in a brain by using large magnets. Researchers hope the new technology will be used in the future to clear out blockages in patients who suffered from strokes and aneurysms. (Image Credit: MIT) ...
The technology uses transdermal optical imaging to diagnose blood pressure using 2-minute videos of the subjects face taken from a smartphone. (Image credit: University of Toronto)   In the not so distant future, we may be able to apply preventative health measures using our smartphones, including measuring blood pressure just by taking a selfie video. Researchers from the University of Toronto have developed a new technology- termed transdermal optical imaging, which measures blood pressu ...
This new metalens can focus and make adjustments for blurriness in real-time. This new lens has similar behavior as the human eye. (Image credit: SEAS)   Researchers at Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) may have just hit a breakthrough in artificial eye technology. The team has developed an adaptive metalens that acts similarly to the human eye. The lens has the ability to focus in real-time and even adjust for astigmatism and image shift, which ofte ...
The Rekognition AI platform is now capable of identifying fear, adding an eight entry in its emotion-detection capability. (Image credit: Amazon)   Amazon’s Rekognition platform is a deep learning image and video analysis service that’s part of the company’s AI software suite, which uses machine-learning and deep-learning APIs to identify scenes, objects, faces, and other objects within those images and video. The platform provides access to face-based user verification b ...
The quantum microphone could help develop more efficient quantum computers. A mockup of an array of nanomechanical resonators designed to generate and trap sound particles, or phonons. (Image credit: Standford University)   High-quality microphones may be good at picking up and carrying sound, but they’re not sensitive enough to catch everything, like the smallest unit of sound known as phonons. Recently, researchers at Stanford University developed a “quantum microphone” ...
Those sweltering Summer and freezing Winter days may be more bearable for people to withstand in the future. It’s all due to Sony’s innovative Reon Pocket, a cooling/heating device that can be worn into the back pocket of a t-shirt designed specifically for the device. Reon Pocket will be shipping out in March 2020, only in Japan and is live on Sony’s crowdfunding website. Prices start at $117 to $175, depending on which version of the Reon Pocket the wearer wishes to purchase ...
Scientists recently developed content lenses made of soft robots that zoom in and out on command. The prototype lenses require you to place electrodes around your eyelids. (Image credit: University of California San Diego)   Glasses and contact lenses help improve our vision, but it still doesn’t give you perfect vision. Sometimes an object is so far in the distance no amount of squinting will help you see it. What if you had a zoom-in option? That’s what scientists at the Univ ...
Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have come up with a way to image polarization out of one snapshot. The tiny, portable camera is the same size as a thumb and can be used in systems of autonomous vehicles, aircraft or even satellites to observe chemistry in the atmosphere, or even be used to detect objects that blend into the background. The team presented their findings in Science.   The polarization camera gives us a glimpse o ...
A friend gave me a couple of Pomona Insulation Piercing Clips which I thought were pretty neat. Apparently they are quite popular with the automotive repair/test crowd. The clips were something I had not seen before, so thought maybe it would be good to share some pics/video if anyone else has not seen these before either.   In brief, they can connect to banana plugs (there is also a version of clip compatible with multimeter test leads) and then the other end can be hooked over an insul ...
The new smart network could drastically change how wearable devices connect to radio waves. These conductive textiles can be integrated into clothing to boost signal up to 1,000 times. (Image credit: NUS)   Wearable technology continues to be a major trend in electronics. From smart watches to smart clothing, developers are finding new ways to integrate technology and the human body. Most wearables are connected to your smartphone and transmit all data via Bluetooth or Wi-Fi signals. The p ...
Neuralink’s HMI uses ‘threads’ that are injected into the brain to tap into neuron activity, which can be read by machines, essentially understanding human thought. (Image credit: Pixabay)   Elon Musk recently unveiled the progress that’s been made with his neurotechnology company Neuralink and their endeavor in developing implantable brain-machine interfaces (BMIs). The company states that they are getting close to fielding human trials next year for their neuron-r ...
By age 45, many people may suffer from an eyesight condition called presbyopia, which causes the lenses to lose elasticity in our eyes. Our vision requires the elasticity to help keep our eyesight focused on nearby objects. There are also some fixes like reading glasses, surgery or progressive lenses that can help to overcome the defect, and as of recent, there’s autofocals. Developed by electrical engineer, Gordon Wetzstein and his team at Stanford University, the prototype glasses are id ...
Scientists from UCLA have discovered a new way to look at nucleation. By using 4D atomic resolution (which is three dimensions of space and time), the team was able to record how atoms rearrange. Their new discovery, which can be found in the journal Nature, offers a different perspective from predictions made on the original theory of nucleation that can be found in textbooks.   Nanoparticles in an iron-platinum alloy changes state three different times. Observations were recorded usin ...
