Charge Your Phone — With a Flick of the Wrist

0 yorum


When it looks like your phone is about to run out of battery, you actually have plenty of juice to spare. The Voltmaker is a device that allows you to make use of that reserve energy in order to charge your phone — all with the flick of a wrist.

A hidden rod that is normally secured to the body using a magnet can be released using a spring-loaded mechanism. Once you release it, you can spin the rod by shaking the device like a rattle — a movement that allows your smartphone to harvest kinetic energy.

By keeping up your enthusiastic rattling for a few minutes, it’s possible to generate enough power to make a quick phone call, play a couple of songs or light the way using an LED torch attachment that fits into the USB port at the opposite end. Read more…

In the shadow of larger announcements during Apple's Worldwide Developers Conference (WWDC) keynote Monday were new AirPort Extreme and AirPort Time Capsule devices.

Apple updated its AirPort Extreme base station ($199.99) to include 802.11ac Wi-Fi, which supposedly works three times faster than Wireless N. The elevated design departs from the previous generation and now has six antennas to improve dispersion of the signal.— three antennas for the 2.4GHz band, three for the 5GHz band. Read more…

Passwords: They’re everywhere, and most of us manage a half-dozen or so, at least. They’re also the weakest link in the authentication chain because humans aren’t great at creating passwords remembering them.

A Motorola executive (and former Defense Advanced Research Projects Agency head) Regina Dugan proposed a solution at the D11 conference: pills and tattoos. Read more…

Lifestyle Like Follow Controversial Iris-Scanning Program Could Keep Kids Safe

0 yorum


Tests of iris-scanning technology were derailed in a central Florida school district recently after parents expressed outrage that they weren't told about the program before their kids' eyes were scanned.

However, iris scanning could provide essential information to parents of bus-riding kids who don't arrive home at the expected time. The mobile devices could also identify the kids as they rush up the steps to board the buses.

Unlike older iris scanners, which required people to stand motionless in front of a screen for several seconds before their identity could be verified, the new devices can identify up to 50 people per minute who pass the scanner, according to Stanley Convergent Security Systems, which provided the scanners to Polk County, Fla., schools.

Students were enrolled in the program by having a photo taken of their iris, which remains unchanged after the first year of life. Iris scans are 200 times more accurate than fingerprints at identifying individuals, Stanley said on its website.

As children board a bus, the scanner takes a photograph of each student's eye. In a fraction of a second, the new photo is matched with an existing one in the school's database, along with the student's name and identification number. Each match is time-stamped and marked with the location, so school officials and parents can immediately see who has gotten on and off a bus.

The system was installed on school buses at Davenport School of the Arts, Daniel Jenkins Academy and Bethune Academy in Polk County, but has been suspended as officials work to address the concerns of parents worried about student privacy. The school sent out letters of apology for its oversight, but remains hopeful the system can be restarted in the future.

"Within seconds, we could tell parents, 'Yes, they got on bus No. 0750. They got on the bus at the high school at 2:05; they arrived at their bus stop at 2:45," Rob Davis, director of support services for Polk County schools, told a local Fox television station.

The school bus iris-scanning system can also be programmed to send text alerts to parents as children board and disembark their buses. In the meantime, parents can use their children's phones to monitor their kids' whereabouts in a similar way; most cellphone carriers provide a family tracking service, and apps can be installed for the same purpose.

However, these phone-dependent methods are only as reliable as the kids' ability to hold onto their phones.
