Touchless gestures powered by ultrasound has become a mark of distinction for Elliptic Labs. The company has new “Multi Layer Interaction” technology designed to bring users intuitive device interactions.

Without touching the device, the person’s hand moves towards the smartphone, the screen lights up and information is displayed. As the person continues moving the hand closer, different information is revealed. With users constantly, frequently, eagerly reaching for their devices throughout the day, Elliptic Labs aims to make a difference in its easy and fast way to get information, from playing games to navigating maps, to using social media, to watching videos. A promotional video says the user can interact above, in front, underneath, double-tapping anywhere around the device, easily turning the device on and off as well. There is an SDK kit for applications. How it works: Ultrasound signals sent through the air from speakers integrated in smartphones and tablets bounce against the hand and are recorded by microphones integrated in the devices. As such, the technology recognizes hand gestures and uses them to move objects on the screen, similar to how bats use echolocation to navigate.

Algolux is a company aiming to tackle blurring problems through computational optics. Algolux said its efforts are presently focused on smartphones and tablets. One can appreciate how this company sees their technology attracting interest in this way. The technology allows for lens designs to be less complex, smaller, lighter and cheaper which would be especially interesting in smartphone imaging where space is at a premium, said Connect, a website on mobile photography technology. The company tells site visitors that “Our computational optics enable better pictures, thinner cameras and cheaper optics.” The technology allows manufacturers’ devices to capture clearer pictures with their existing equipment, including in low-light conditions. Also, the quantity and quality of optical elements needed are diminished; manufacturers can obtain desirable results at a lower cost.

Traditional optics have hit a wall, according to the company. Their size can no longer be reduced significantly for cameras inside thin devices such as smartphones and tablets.”Lenses in smart devices are small and plastic (for the most part), and do not have the quality of a full-sized optical system, especially for low-light and night-time pictures. As sensors and pixels get smaller, the probability of blur and other aberrations in pictures increases.”

When vendors send out announcements of long battery life and juicing strategies for electronic gadgets, interest is assured; the bad news is that interest is assured because consumers are still eagerly looking for less bother and less time needed to keep their smartphones and other mobile gadgets up and running. Intel is aware of the challenge, what with wearables on tap in an assortment of form factors. To be sure, Intel would like to be in the frontlines of technology giants providing the buying public with finer solutions.

“What’s New with Wireless Charging?” Intel asked in July. Intel’s answer, “If you’ve been keeping up with trade shows and tech blogs, you might think that some new breakthrough in wireless energy transfer has taken place in the past year. It hasn’t.” Nikola Tesla worked on wireless power transmission before the turn of the 20th century; his inductive charging techniques would see a renaissance some five decades after his death in 1943, said Intel. That has not stopped technologists, however, from asking what comes next. Today, said Intel, the idea and the technology is gaining momentum.

This week’s news headlines of Intel saying its charging bowl will be available by the end of this year will no doubt interest readers and will please those who saw the bowl earlier this year at the Consumer Electronics show, and kept sending e-mails to Intel asking when it will be ready. Earlier this year, it was clear that Intel was working on a day not too distant in the future when people in PC environments could enjoy docking and charging activities as a wire-free experience. Intel revealed at the Computex trade show in Taipei, via an Intel demonstration by Kirk Skaugen, Intel’s senior vice president and general manager of the PC Client Group, that the chipmaker was in fact working on wireless technologies to help deliver a new normal. Skaugen demonstrated how wireless technology could be integrated into a table that could simultaneously charge a laptop, phone, headset and tablet. In January, the company had really whetted appetites for changes in showing a wireless charging bowl at CES. The bowl looks like the standard bowl one might place on a table at home to hold keys, loose coins, or other items.

Shawn Frayne and Alex Hornstein, two young inventors based in the Philippines, are taking their passion for clean free energy and developing a way to make it accessible and cheap for everyone. These guys are working restlessly to provide a product that could be used by practically anyone to make homemade solar panels.

The factory is small enough to fit on a desktop and efficient enough to produce 300k to one million panels per year, up to one every 15 seconds. By cutting out much of the labor intensive process, which represents 50% of the total cost, this machine can dramatically reduce the price of solar. Their pocket solar panel producer can change the way the world views electricity. Image credit: YouTube/SciFri

(Phys.org) —Wi-Fi makes all kinds of things possible. We can send and receive messages, make phone calls, browse the Internet, even play games with people who are miles away, all without the cords and wires to tie us down. At UC Santa Barbara, researchers are now using this versatile, everyday signal to do something different and powerful: looking through solid walls and seeing every square inch of what’s on the other side. Built into robots, the technology has far-reaching possibilities.

“This is an exciting time to be doing this kind of research,” said Yasamin Mostofi, professor of electrical and computer engineering at UCSB. For the past few years, she and her team have been busy realizing this X-ray vision, enabling robots to see objects and humans behind thick walls through the use of radio frequency signals. The patented technology allows users to see the space on the other side and identify not only the presence of occluded objects, but also their position and geometry, without any prior knowledge of the area. Additionally, it has the potential to classify the material type of each occluded object such as human, metal or wood.

The combination of imaging technology and automated mobility can make these robots useful in situations where human access is difficult or risky, and the ability to determine what is in a given occluded area is important, such as search and rescue operations for natural or man-made disasters.

If you’ve got an iPhone, there is a good chance you also have a MacBook. The MagSafe charger on Apple’s laptop offerings is easy to use, leading some to want an iPhone with the same functionality. A recently funded Kickstarter is attempting to bring it to us, and even slaps in a battery pack for good measure.

The draw for Cabin is twofold: the magnetic charging, and the battery pack. The battery pack slips onto the rear of the device, much like we see with the Case+ lineup from Logitech. Aluminum, Cabin is relying on your sensitivity to style for the battery pack. At 2200mAh, it’ll charge you up more than once, too.

The magnetic charging is a bit more adapter than anything else. By taking a lightning connector and working a pinned magnetic charger on the end, we get simple, easy, and (hopefully) effective charging. What you won’t be able to do is use your MacBook charger. Cabin includes a Lightning adapter and dock (if you spend a touch more), though.

Researchers at the University of California, Riverside in the US have developed lithium-ion batteries that substitute graphite with silicon extracted from sand and last three times longer than current products.

The negative side of lithium-ion batteries, or anode, is made with graphite, and scientists have been trying to find a substitute material that could make batteries last longer. One of the options is silicon, which can store up to 10 times more energy than current materials, but it’s expensive and hard to produce in large quantities.

But then a very simple but brilliant option revealed itself to graduate student Zachary Favors. As Gizmag reports, Favors was relaxing after surfing when he noticed something quite special: sand. Sand is made of quartz, or silicon dioxide, and other materials, so Favors thought he could extract the silicon and use it to make batteries.
