Infrared headset nixes radiation Many cell-phone users have taken to using hands-free headsets to avoid the microwave radiation the devices emit, but the electrical wires that connect the headsets to the phones can also act as antennas for microwaves. A headset that connects via infrared light sidesteps the radiation problem. mark for My Articles similar articles

Something GNU in Radio Imagine an infinitely flexible radio. Simply by loading in various free programs, you could turn the device into a multistandard mobile phone, a GPS locator, an AM-FM stereo receiver or even a portable TV. That's the goal of the GNU Radio project, which aims to help radio escape from its box. mark for My Articles similar articles
