Hi-Tech Arena

New screen technologies rarely enter the market. The two biggest reasons, among all of these concerns, are cost and appearance. If a display costs more to manufacture than competitors, it needs to look great. If it doesn’t look amazing, then consumers won’t buy it. What makes CLEARink a contender in many different markets: it’s both cheaper to produce and looks better than its e-paper competitors. The technology brims with so much promise that it won Best of Show at Display Week 2017. Sri Peruvemba, Head of Marketing at CLEARink Displays, answered several questions regarding CLEARink Display’s electrophoretic technology. Here are just a few reasons why CLEARink seems destined to become a mover and shaker in the e-reader space. CLEARink Looks Better Than E Ink The CLEARink technology looks like E Ink, but with some big differences. While both share an underlying technology (electrophoresis), the secret behind CLEARink lies in a new type of ink, co-developed with Merck, and a...

I think this is the answer for , can a Robot replace a human security guards ! 

Get this. You know Google Glass, the futuristic headset that sells for $1,500? According to a new report from TechInsight's Teardown.com, the high-tech headpiece only costs around $80 to produce. The site secured a pair of the pricey specs and then ripped them apart, piece by piece, to determine the estimated price of each component. The surprising finding? Their preliminary analysis revealed that the bill of materials for all the parts and pieces used to make Google Glass adds up to a measly $79.78. The most expensive component used in Glass is the Texas Instruments OMAP 4430 applications processor, which comes in at around $13.96. The display, touch screen, and glass cost just $3, while the battery comes in at $1.14, and the camera is worth $5.66. Non-electrical material used in the device costs $13.63, while the 16GB of NAND flash memory from Toshiba totals $8.18, and assembly and testing comes in at $2.15. Google, meanwhile, says Teardown.com's assessment is n...

For a more detailed analysis of this catastrophic bug, see  this update , which went live about 18 hours after Ars published this initial post. Researchers have discovered an extremely critical defect in the cryptographic software library an estimated two-thirds of Web servers use to identify themselves to end users and prevent the eavesdropping of passwords, banking credentials, and other sensitive data. The warning about the bug in OpenSSL coincided with the  release of version 1.0.1g of the open-source program , which is the default cryptographic library used in the Apache and nginx Web server applications, as well as a wide variety of operating systems and e-mail and instant-messaging clients. The bug, which has resided in production versions of OpenSSL for more than two years, could make it possible for people to recover the private encryption key at the heart of the digital certificates used to authenticate Internet servers and to encrypt data traveling between ...

A medical device, once its job is done, could harmlessly melt away inside a person's body. Or, a military device could collect and send its data and then dissolve away, leaving no trace of an intelligence mission. Or, an environmental sensor could collect climate information, then wash away in the rain. It's a new way of looking at electronics: "You don't expect your cell phone to dissolve someday, right?" said Reza Montazami, an Iowa State University assistant professor of mechanical engineering. "The resistors, capacitors and electronics, you don't expect everything to dissolve in such a manner that there's no trace of it." But Montazami thinks it can happen and is developing the necessary materials. He calls the technology "transient materials" or "transient electronics." The materials are special polymers designed to quickly and completely melt away when a trigger is activated. It's a fairly new field of study...

Newcastle University is trialling new technology to help patients suffering from Parkinson's disease live more independently by reminding them to swallow, speak up and take their medication Google Glass is being used by people suffering from Parkinson’s disease in a groundbreaking experiment to see if the technology can help improve their day-to-day lives. The technology, which is not yet available in Britain, reminds the patients to take their medication, contacts relatives in an emergency and can even prevent debilitating episodes of paralysis – known as ‘freezing.’ The system works like a hands-free smartphone, displaying information on the lens of the Glass. It is voice-operated and linked to the internet. Doctors at Newcastle University have created a programme that helps control behaviour associated with Parkinson's, such as reminding the individual to speak up or to swallow to prevent drooling. “The beauty of this research project is we are desi...

Snoopy  is a distributed tracking and profiling framework to perform some pretty interesting tracking and profiling of mobile users through the use of WiFi. The talk was well received (going on what people said afterwards) by those attending the conference and it was great to see so many others as excited about this as we have been. In addition to the research, we both took a different approach to the presentation itself. A 'no bullet points' approach was decided upon, so the slides themselves won't be that revealing. Using Steve Jobs as our inspiration, we wanted to bring back the fun to technical conferences, and our presentation hopefully represented that. As I type this, I have been reliably informed that the DVD, and subsequent videos of the talk, is being mastered and will be ready shortly. Once we have it, we will update this blog post. In the meantime, below is a description of the project. Background There have been recent initiatives from numerous gover...

The EU successfully pushed for voluntary adoption of a  cellphone charging standard  a few years ago, and it's now close to making that standard mandatory. The European Parliament has  voted in favor  of a draft law requiring that cellphones work with a common charger. Provided the Council of Ministers green lights the regulation, EU countries will have until 2016 to put it into their local laws; phone makers will have until 2017 to change their hardware. The charger requirement is a formality when  many phone designers  already support the concept, but it could force some companies to shape up -- and spare more Europeans from tossing out power adapters when they switch handsets.

Samsung's Galaxy S5 may be getting lots of smart new accessories, but the Korean smartphone maker is also making sure its lower-powered phones get some love too. After including various software usability functions in the Galaxy Core Advance at the end of last year, the company today introduced three new accessories that have been designed specifically to help disabled or visually impaired users do more with their Android device. First up is the Optical Scan Stand, a raised bracket that automatically triggers the phone's OCR features to recognize and read aloud text placed in front of the phone. There's also Voice Labels, which are similar to Samsung's NFC-equipped TechTile stickers, but let visually impaired users make voice notes or record short explanations on how to use various devices around the home. Perhaps the most impressive accessory of the three is Samsung's Ultrasonic Cover: a specialized case that uses sound waves to detect people or objects (in...

When UK Prime Minister David Cameron gave a speech at CeBIT this year, what examples did he use to highlight tech innovation in Britain? Yes, ARM and Imagination were on his list, but he also referred to the tiny, Linux-based computer called Raspberry Pi, which has now sold over 2.5 million units. In a timely fashion, the Pi's makers, element 14, have just announced a new $33,Wolfson-powered audio card that should give the device a broader range of functions. The add-on board fits right onto the Pi's P5 pins and carries a Wolfson audio processor that supports high-res audio up to 24-bit / 192KHz, which can be played via a direct connection to an amp over 3.5mm line-out or alternatively via a digital S/PDIF output. Audio recording, meanwhile, comes courtesy of two onboard MEMS mics (useful for things like voice control), a 3.5mm mic jack and a digital S/PDIF input. It's true that some of these audio capabilities have already bee...

Amal Graafstra snaps on a pair of black rubber gloves. “Do you want to talk about pain management techniques?” he asks. The bearded systems administrator across the table, who requested I call him “Andrew,” has paid Grafstra $30 to have a radio-frequency identification (RFID) chip injected into the space between his thumb and pointer finger, and as Graafstra describes Lamaze-type breathing methods, Andrew looks remarkably untroubled, in spite of the intimidatingly high-gauge syringe sitting on the table between them. Graafstra finishes his pain talk, fishes a tiny cylindrical two-millimeter diameter EM4012 RFID chip out of a tin of isopropyl alcohol, and drops it into the syringe’s end, replacing the RFID tag intended for pets that came with the injection kit. He swabs Andrew’s hand with iodine, carefully pinches and pulls up a fold of skin on the top of his hand to create a tent of flesh, and with the other hand slides the syringe into the subcutaneous layer known as the fascia...

There is an entire science devoted to how humans interact when looking at a page.  Large advertisers have spent millions learning the exact wording for the ad, where to place it, how large it should be, and even what color. As a blogger, you don’t really care that much; nor do you have the time to become a psychology expert.  However you do need to experiment and test to learn how to increase Adsense clicks. After all, an ad spot on your blog is valuable real estate. If it’s not getting enough clicks, you need to rethink your strategy. Some people smother their blog in ads. I have seen blogs with sidebars on either side and ads from top to bottom, most of them flashing messages.  I have even seen blogs still putting ads into their content stream. Not The Best Adsense Strategy Imagine if you go into a room to talk to someone and 15 people surround you; talking to you all at once.  After a few seconds, you would become so frustrated you would probably sc...

The National Security Agency is using secret wireless technology that allows it to access and alter data on computers, even when they are not connected to the Internet, according to a New York Times report. Since 2008, the agency has been increasingly using "a covert channel of radio waves" that can transmit from hardware installed in the computers, according to NSA documents and experts interviewed by the Times. Signals can then be sent to briefcase-size relay stations miles away, according to the report. The NSA has also installed surveillance software on nearly 100,000 computers around the world, according to the Times. The newspaper said the Chinese Army was a frequent target of such technology but said there was no evidence that the agency used either technology inside the US. Repeating earlier denials that its data collection activities are arbitrary or unconstrained, the NSA rejected any comparison to Chinese attackers who have been accused to planting simil...
