Radio
University of Utah engineers have developed a system that uses a wireless network of radio transmitters to track people moving behind solid walls. They say the system could help police, firefighters and other emergency services capture intruders, and rescue hostages, fire victims or elderly people who fall in their homes by letting them know where to focus their attentions. The engineers’ system uses radio tomographic imaging (RTI) to “see”, locate and track people or objects in an area surrounded by inexpensive radio transceivers that send and receive signals.

Become a human antenna with your own carpet radio
When I was young I had a tall, wiry friend we nicknamed ‘the Human Antenna’. Now anyone, regardless of height, can rival my friend just by walking on a unique carpet recently created by Swiss designer Florian Kräutli.

Not long ago, radio manufacturers had only to worry about the basic look of their devices. Rarely were new stations added, reception methods hadn’t changed in a long time and, generally, smaller was better.

Now a radio has to be a veritable Swiss army knife of appliances, and this is where the new Sensia from Pure excels. Its list of features includes a large color touch screen display, DAB, FM stereo and digital radio with full Band III, wireless media streaming, input from iPods/iPhones and MP3 players, and Pure Apps that let you connect with Facebook, Twitter, Picasa and thousands of podcasts.
