Tesco in talks over facial recognition tech for stores

The supermarket giant Tesco is examining facial recognition technology that could help it recognise high-value shoppers and shoplifters, according to NEC.NEC senior marketing coordinator George Gimenez told ZDNet UK at the Unified Communications (UC) Expo 2011 in London that Tesco is interested in the technology, called Neoface, because it could help the company identify its top customers as they walk into a branch.

A bright idea for wasteful office lighting

Commercial office buildings are one of the main culprits of the current climate crisis. They consume large amounts of electricity and release excessive carbon emissions into the atmosphere. Adura Technologies has developed a mesh-based lighting system that is reducing costs and consumption inside buildings. The technology consists of wireless radios that plug into florescent light fixtures giving employees more control over their personal lighting space. Adura has also created a dual motion sensing-personal control system that is being used at UC Berkeley that allows students to break the hard-wired connection and control their lighting from their desktop PCs.

GPS cell phones plot, predict traffic

With the popularity of GPS-enabled cell phones, it makes sense to use that mapping technology to plot traffic speeds. A new UC Berkeley and Nokia pilot program tests out the tech in the San Francisco Bay Area, where CNET's Kara Tsuboi gives it a spin.

Cellphones used for medical imaging?

A team of engineers at the University of California at Berkeley has developed a technique for transmitting medical images via cellphones. This potentially could bring medical imaging to the 'three-quarters of the world's population which has no access to ultrasounds, X-rays, magnetic resonance images, and other medical imaging technology.' The lead researcher said that this new system would make imaging technology inexpensive and accessible in non-industrialized countries. As medical images are usually pretty large, I was a little bit skeptical when I first read the UC Berkeley news release. But as the researchers have found a way to reduce these images to a mere kilobytes, it can actually be feasible. But read more about this brilliant idea...

Diamonds are fuel cells' best friends

Researchers at UC Davis have used nanocrystals made of diamond-like cubic zirconia to develop cooler fuel cells. Even if hydrogen fuel cells have been touted as clean energy sources, current fuel cells have to run at high temperatures of up to 1,000 °C. This new technology will allow fuel cells to run at much lower temperatures, between 50 and 100 °C. Obviously, this could lead to a widespread use of fuel cells, which could become a realistic alternative power source for vehicles. The researchers have applied for a patent for their technology, but don't tell when fuel cells based on their work are about to appear.
