Samsung’s 950 Pro SSD achieves 2,500MB/s read speeds
Posted by Shailesh Prasad in categories: computing, electronics
Solid state drives are now the clear storage solution choice inside laptops and desktop PCs if you value speed. But as the NAND flash memory inside SSDs has improved, the drives have come up against some limitations, the main one being a SATA connection. We typically see SATA-connected SSDs top out at 550MB/s read and write speeds.
Storage companies have attempted to overcome that limitation with a move to PCI Express. Samsung made the move to PCIe with the 850 Pro SSD, which connected through an M.2 interface. However, that SSD was still limited to read and write speeds in the 500MB/s range. But today, Samsung has unveiled the 950 Pro SSD, and it blows everything that has come before out the water.

Digestible batteries needed to power electronic pills
Posted by Shailesh Prasad in categories: biotech/medical, electronics, engineering, materials
Imagine a “smart pill” that can sense problems in your intestines and actively release the appropriate drugs. We have the biological understanding to create such a device, but we’re still searching for electronic materials (like batteries and circuits) that pose no risk if they get stuck in our bodies. In Trends in Biotechnology on September 21, Christopher Bettinger of Carnegie Mellon University presents a vision for creating safe, consumable electronics, such as those powered by the charged ions within our digestive tracts.
Edible electronic medical devices are not a new idea. Since the 1970s, researchers have been asking people to swallow prototypes that measure temperature and other biomarkers. Currently, there are ingestible cameras for gastrointestinal surgeries as well as sensors attached to medications used to study how drugs are broken down in the body.
“The primary risk is the intrinsic toxicity of these materials, for example, if the battery gets mechanically lodged in the gastrointestinal tract–but that’s a known risk. In fact, there is very little unknown risk in these kinds of devices,” says Bettinger, a professor in materials science and engineering. “The breakfast you ate this morning is only in your GI tract for about 20 hours–all you need is a battery that can do its job for 20 hours and then, if anything happens, it can just degrade away.”

The one (gesture control) ring to rule them all
Posted by Shailesh Prasad in categories: electronics, energy
While many companies are tinkering with lasers, ultrasound and even arm muscles for touchless gesture control on portable devices and desktop PCs, Japan’s 16Lab just wants to put a pretty ring on you. The yet-to-be-named titanium wearable is designed by the award-winning Manabu Tago, and it features ALPS Electric’s tiny module (5.05 × 5.65 × 2.5 mm) that somehow manages to pack Bluetooth Smart radio, movement sensor, environment sensor plus antennas — there’s a video demo after the break. Despite its custom-made 10mAh lithium polymer cell, 16Lab is aiming for at least 20 hours of battery life. This is possible mainly because you have to place your thumb on the top pad (with the ring’s wedge pointing away from the user) to enable the sensors — upon which point the ring vibrates to confirm that it’s active. It’s then just a matter of waving and tilting your hand until you’re done.

Algolux tackles optics challenges in smartphones
Posted by Shailesh Prasad in categories: electronics, mobile phones
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.”

Intel wireless charging in a bowl coming sooner than later
Posted by Shailesh Prasad in categories: electronics, energy, mobile phones
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.

Open Source ‘Solar Pocket Factory’ Can 3D Print a Solar Panel Every 15 Seconds
Posted by Shailesh Prasad in categories: 3D printing, computing, electronics, mobile phones, solar power, sustainability
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

Control Google Glass with your mind… and a second headset
Posted by Shailesh Prasad in categories: electronics, neuroscience
Up until now, you can only navigate Google Glass by touching or talking to it, but London-based firm This Place just made it possible to control the device using something else: your brainwaves. The company just released an open source application called MindRDR that gives you something akin to very, very limited telekinetic abilities — so long as you have both Google Glass and Neurosky’s EEG biosensor headset. See, MindRDR serves as the bridge that connects the two, translating the brain activity from the EEG biosensor into executable commands for the high-tech eyewear. At the moment, the software can only take pictures and upload them to either Facebook or Twitter, but This Place released the app for free on GitHub in hopes that other developers will use it for more advanced projects.
MindRDR shows up as a thin white line on Glass’s screen, which moves upwards the more the user concentrates. Once that line reaches the very top, it snaps a picture of whatever you want — you simply need to repeat the process to upload the image to a social network. In the future, though, its creators believe that the app could be a huge help to people who can’t move on their own. These include quadriplegics, those with multiple sclerosis, and especially those suffering from locked-in syndrome.
