Gunze Introduced Its New Touch Screen Panel

Gunze Ltd exhibited a prototype of a touchscreen panel that specifies a person touching it at the 11th International Nanotechnology Exhibition & Conference in Tokyo which took place from February 15 to 17, 2012. This is something that current multi-touch screens are incapable of discerning and although you may not necessarily see the need on small personal mobile devices, Gunze’s tech is meant for tabletop multiplayer arcade games. The Gunze prototype had a capacitive touchscreen embedded in a tabletop with four electrodes located around the touch panel. In order for the touchscreen to differentiate between the players around the table, each player would have to have one hand hold the electrode while the other hand touched the screen.

iPad 3 Logic Board with A5X System on a Chip

The forum post at Chinese site WeiPhone offers a photo of what is claimed to be the iPad 3’s logic board showing an A5X system on-a chip. Apple is expected to introduce an upgraded processor and graphics package for the iPad 3, with the assumption being that it would be called the A6 after the A4 initially appeared in the original iPad and iPhone 4 and was succeeded by the A5 in the iPad 2 and iPhone 4S. But if this photo is to be believed, that assumption appears to have been incorrect, with Apple instead having branded the upgraded package with the A5X name. A date code of “1146” on the A5X indicates that it was manufactured in the 46th week of 2011, which would have corresponded to November 14-20.

Physicists Create a Working Transistor From a Single Atom

Australian and American physicists have built a working transistor from a single phosphorus atom embedded in a silicon crystal.The group of physicists, based at the University of New South Wales and Purdue University, said they had laid the groundwork for a futuristic quantum computer that might one day function in a nanoscale world and would be orders of magnitude smaller and quicker than today’s silicon-based machines. The device comes with small visible markers that are etched onto its surface in order for researchers to connect metal contacts and apply a voltage.

Cornell University and University of Chicago Created Robotic Arm

Cornell University and the University of Chicago have developed a new robotic arm that works in much the same way as many others we’ve seen, but with a twist. Unlike most robotic arms we’ve seen which emulate a human hand, the researchers have created what they call the “simple passive universal gripper.” This uses a membrane filled with a mass of granular material (like a balloon filled with sand) connected to an air compressor and vacuum. To pick up an object, the balloon pushes down on it and then the vacuum kicks in, causing the balloon to harden and grip the object. To throw the item, the process is reversed, with a compressor quickly pumping air into the membrane to project the grabbed object at speed.

Invisibility Cloak Conceals 3D Objects

Scientists in the United States have made a further step towards creating an “invisibility cloak” by masking a large, free-standing object in three dimensions. The lab work is the latest advance in a scientific frontier that uses novel materials to manipulate light, a trick that is of huge interest to the military in particular. Reporting in the New Journal of Physics, researchers at the University of Texas in Austin cloaked a 7.2-inch cylindrical tube from light in the microwave part of the energy spectrum.This newest cloak makes 3D objects invisible without using reflective surfaces or specialized microwave chambers.
