This allows side-by-side comparison, picture-in-picture, and overlay of picture and thermal graphic. Nice long battery life.
Self-service fever scanner uses fist or wrist
FeverWarn is a new, non-contact device that determines if a user has a fever instantly -- simply by scanning the wrist or fist. The technology's creators at MachineSense, along with some university studies, say these hand areas are consistently some of the most reliable on the body for accurate temperature scanning. The FDA-compliant FeverWarn unit can be installed in front lobbies, security checkpoints, manufacturing entrances, school entrances, and any other place where the initial entryway is your first line of defense. A red or green light indicates pass or fail. Provides outputs for triggering auxiliary doors or gates.

Bend it, cut it, shape it: Flexible micro LEDs may reshape future of wearable technology

University of Texas at Dallas researchers and their international colleagues have developed a method to create micro LEDs that can be folded, twisted, cut, and stuck to different surfaces.
The research, published online in June in the journal Science Advances, helps pave the way for the next generation of flexible, wearable technology.
Used in products ranging from brake lights to billboards, LEDs are ideal components for backlighting and displays in electronic devices because they are lightweight, thin, energy efficient, and visible in different types of lighting. Micro LEDs, which can be as small as 2 micrometers and bundled to be any size, provide higher resolution than other LEDs. Their size makes them a good fit for small devices such as smart watches, but they can be bundled to work in flat-screen TVs and other larger displays. LEDs of all sizes, however, are brittle and typically can only be used on flat surfaces.
The researchers' new micro LEDs aim to fill a demand for bendable, wearable electronics.
"The biggest benefit of this research is that we have created a detachable LED that can be attached to almost anything," said Dr. Moon Kim, Louis Beecherl Jr. Distinguished Professor of materials science and engineering at UT Dallas and a corresponding author of the study. "You can transfer it onto your clothing or even rubber -- that was the main idea. It can survive even if you wrinkle it. If you cut it, you can use half of the LED."
Researchers in the Erik Jonsson School of Engineering and Computer Science and the School of Natural Sciences and Mathematics helped develop the flexible LED through a technique called remote epitaxy, which involves growing a thin layer of LED crystals on the surface of a sapphire crystal wafer, or substrate.
Typically, the LED would remain on the wafer. To make it detachable, researchers added a nonstick layer to the substrate, which acts similarly to the way parchment paper protects a baking sheet and allows for the easy removal of cookies, for instance. The added layer, made of a one-atom-thick sheet of carbon called graphene, prevents the new layer of LED crystals from sticking to the wafer.
"The graphene does not form chemical bonds with the LED material, so it adds a layer that allows us to peel the LEDs from the wafer and stick them to any surface," said Kim, who oversaw the physical analysis of the LEDs using an atomic resolution scanning/transmission electron microscope at UT Dallas' Nano Characterization Facility.
Colleagues in South Korea carried out laboratory tests of LEDs by adhering them to curved surfaces, as well as to materials that were subsequently twisted, bent, and crumpled. In another demonstration, they adhered an LED to the legs of a Lego minifigure with different leg positions.
Bending and cutting do not affect the quality or electronic properties of the LED, Kim said.
The bendy LEDs have a variety of possible uses, including flexible lighting, clothing, and wearable biomedical devices. From a manufacturing perspective, the fabrication technique offers another advantage: Because the LED can be removed without breaking the underlying wafer substrate, the wafer can be used repeatedly.
"You can use one substrate many times, and it will have the same functionality," Kim said.
In ongoing studies, the researchers also are applying the fabrication technique to other types of materials.
"It's very exciting; this method is not limited to one type of material," Kim said. "It's open to all kinds of materials."
