Vicarious AI breaks CAPTCHA ‘Turing test’

October 28, 2013

CAPTCHA - featured

Vicarious, a startup developing artificial intelligence software, today announced that its algorithms can now reliably solve modern CAPTCHAs (Completely Automated Public Turing tests to tell Computers and Humans Apart).

Vibration-powered Generators Replace AA, AAA Batteries

July 19, 2010

(Brother Industries Ltd.)

Brother Industries Ltd. has developed small vibration-powered generators that can replace AA and AAA batteries in devices that do not always consume electricity and have a power consumption of about 100mW (a maximum for a normal remote).

The battery-shaped case includes an electromagnetic induction generator and a 500mF double-layer capacitor. The average output of the AA-size generator is 10 to 180mW (frequency: 4-8Hz).

Vibrating touch screen puts Braille at the fingertips

April 1, 2009

A new way of presenting Braille characters on a mobile device could lead to a Braille-ready touchscreen phone.

University of Tampere in Finland and colleagues used a Nokia 770 Internet Tablet, which has a piezoelectric material built into the touch screen that vibrates when an electric signal is applied to it. To generate characters, they installed software that represents a raised dot as a single pulse of intense vibration,… read more

Veteran’s new artificial leg has artificial intelligence

April 11, 2007

Ossur’s “Power Knee” prosthetic leg allows amputees to walk longer while experiencing less physical toll.

It uses sensors located on the artificial knee and on the insole of the other leg, which sends information about their position at high speed. Gyroscopes on the artificial knee and on the ankle also send information about the tilt of the limbs. All of this information flows to a microprocessor in the knee,… read more

The Long Now Foundation has developed a modern Rosetta Stone — a backup of human languages that future generations might cherish — etched on a 3-inch nickel disc with an estimated lifespan of 2,000 to 10,000 years.

The disc contains an archive of 13,500 scanned pages in more than 1,500 human languages with human-readable scripts, text, and diagrams (using a microscope). The plan is to replicate the disc and… read more
