Prosthetic hands can now feel

A 28-year-old who has been paralyzed for more than a decade as a result of a spinal cord injury has become the first person to be able to “feel” physical sensations through a prosthetic hand directly connected to his brain, and even identify which mechanical finger is being gently touched.The advance, made possible by sophisticated neural technologies developed under DARPA’s Revolutionizing Prosthetics points to a future in which people living with paralyzed or missing limbs will not only be able to manipulate objects by sending signals from their brain to robotic devices, but also be able to sense precisely what those devices are touching.“We’ve completed the circuit,” said DARPA program manager Justin Sanchez. “Prosthetic limbs that can be controlled by thoughts are showing great promise, but without feedback from signals traveling back to the brain it can be difficult to achieve the level of control needed to perform precise movements. By wiring a sense of touch from a mechanical hand directly into the brain, this work shows the potential for seamless bio-technological restoration of near-natural function.

The Sensel Morph – finally a replacement Fingerworks Touchstream!

These guys have launched a wildly succesfull kickstarter to produce what is basically a large touchpad. You can print 3D overlays which magnetically lock into place. Programming new overlays shouldn’t be too tough. It’s sensitive enough to detect paint brushes. Now let’s hope it can be a keyboard with the pinch and zoom and multifinger gestures the guys at Fingerworks invented before it was bought up (and then commercially killed) by Apple!

Lenovo considers re-using their best design

Redesigning a laptop with the black rubberised outside, using the old style, non-chicklet keyboard, with red dot and forward and back buttons next to the arrow keys – all the best they got rid of after the 520, but then thin and powerful! Hope they also consider a serial port on it, as well as a built in optical drive and seperate buttons from the mousepad. I might forgive their spyware policy – hey, I reinstall linux on it anyway!

ThinkPad Time Machine?

Scientists Just Invented the Neural Lace

A group of chemists and engineers who work with nanotechnology published a paper this month in Nature Nanotechnology about an ultra-fine mesh that can merge into the brain to create what appears to be a seamless interface between machine and biological circuitry. Called “mesh electronics,” the device is so thin and supple that it can be injected with a needle — they’ve already tested it on mice, who survived the implantation and are thriving. The researchers describe their device as “syringe-injectable electronics,” and say it has a number of uses, including monitoring brain activity, delivering treatment for degenerative disorders like Parkinson’s, and even enhancing brain capabilities.

lenovo thinkpad t520 – last of the master laptops

This is the last ThinkPad with the old keyboard, before they introduced the chicklet style. Of course, the backlighting they got with the new keyboard of the T530 was nice, and the replacement of the page up / pagedown / escape keys was debated, but the spacing between the keys and the lower quality was a turn off for most people.

Of course the T530 keyboard was built in different qualities:

“New FRU for keyboard that is great:  04W3063
Old FRU of keyboard that was lousy:  04W3137

It’s also easy to tell which one you have – remove the trackpoint cap:

04W3063 = yellow under trackpoint
04W3137 = blue under trackpoint”

One way to improve your T520 is to upgrade the screen for under $100,- to full HD

And there is a way to get the T520 keyboard onto a T530. You can remap a lot of the keys and get quite a way, but not all the way…

Good luck!

Star Wars-style ‘bionic hand’ fitted to first patients

The technique required the men to have their lower arms amputated and fitted with a robotic replacement which responds to electrical impulses when the muscles contract in the same way as a real hand.

“In effect, brachial plexus avulsion injuries represent an inner amputation, irreversibly separating the hand from neural control,” said Professor Oskar Aszmann, Director of the Christian Doppler Laboratory for Restoration of Extremity Function at the Medical University of Vienna, who pioneered the technique.

fitlet – tiny fanless pc, competes with Intel NUC

CompuLab is introducing fitlet – a miniature 0.22l fanless quad-core PC that is not only packing more features than any other PC in its class, but is also designed from the ground up for unprecedented openness: Memory, storage, networking, extension cards and operating system can all be easily installed and upgraded by the user.

The Linux version of fitlet was developed with the Linux Mint team and will be available under the “MintBox Mini” brand.

fitlet is powered by latest AMD low-power APU and is built into a sleek, passively-cooled ruggedized housing. Three fitlet models are offered in various configurations ranging from a plug-and-play Windows PC to a barebone system priced at $129. All models come with a 5 year warranty.

Five Mechanical Gaming Keyboards Compared

When you’re on the path to becoming a power user, you begin to notice certain things that the average person might not. One of those is the difference between typing on a sweet mechanical keyboard with luxurious key action versus pounding away on a run-of-the-mill squishy plank that relies on mushy membranes to register your keystrokes. The difference may seem subtle to the uninitiated, though even casual typists can recognize that there’s something inherently superior about typing on a mechanical keyboard, even if they can’t pinpoint what exactly it is.Of course, we know it’s the mechanical key switches that are responsible for elevating the typing experience. These are better than the rubber domes found in membrane keyboards that used to dominate the market in a number of ways, including feel, responsiveness, and durability.

Touch 3D shapes in mid-air using ultrasound

We present a method for creating three-dimensional haptic shapes in mid-air using focused ultrasound. This approach applies the principles of acoustic radiation force, whereby the non-linear effects of sound produce forces on the skin which are strong enough to generate tactile sensations. This mid-air haptic feedback eliminates the need for any attachment of actuators or contact with physical devices

NVidia optimised games are being crippled for AMD by NVidia

Because NVidia has a program called Gameworks, which developers can sign up for to optimise their game for NVidia cards – 60% of the market. The closed and proprietary Gameworks makes it almost impossible to optimse for AMD, which means that $500,- AMD cards perform worse than $300,- NVidia cards, unless the developer has spent a huge time and investment from the start of the project to optimise for both brands. AMD can’t fix this with a driver update, because reverse engineering the NVidia Gamesworks is difficult and the system is filled with obscure cruft and worthless junk, making it difficult to find out how to optimise the driver for it.
