"Kitching" Atomic Magnetometers

Magnetic fields are everywhere, from the human body with a metal buried in the mine. Even molecules such as proteins to produce their own magnetic fields. Both magnetic resonance imaging (MRI), a description of the body, and NMR spectroscopy (NMR) studies of protein and other substances, such as oil, depending on the magnetic information. But this current sensor to detect the weak, but significant magnetic fields are weak. Some portable and inexpensive, but not very sensitive, very sensitive, but also other stationary, expensive and power.

Kitching Now John, a physicist at the National Institute of Standards and Technology in Boulder, CO, is the development of small, low-power magnetic sensors almost as sensitive as the big, expensive land. About the size of a thick grain rice, called the atomic magnetometer sensors. Kitching hope that one day in the portable MRI machine is faster and cheaper detectors for blind pedestrians.

Small sensor that consists of three parts, vertically in the silicon chip. Ready for infrared laser and infrared photo-detector silicon sandwich and a glass cube with the evaporated cesium atoms. In the absence of a magnetic field, the laser light by cesium atom. Even before the very weak magnetic fields when the atom to change, so that they absorb light in proportion to the strength of the field. This amendment is supported by photo cells. "This is a simple configuration with highly good sensitivity," Kitching says.

Google Plans to Take Over TV, Can They???

Google may win on TV? Yesterday I spoke with Keval Desai, product manager Google TV unit, and it was good you know I can.

"As Internet TV," says Desai. From the perspective of advertisers, you have a point. In 1980 the popular television program, such as the Cosby Show is one half of the total population in the United States is now one of the best seller, for example, American Idol, the capacity of the four spectators. The difference is that now is a few tens of channels, each group of visitors. Desai as a reference, via the Internet: the audience, who already have, but have different contents.

Thus, television production, such as Google Adwords. Advertisers select keywords and cost per day (per thousand population in the notice.) Systems, to learn where and when you must. Google ready to offer other web sites: the role of the early start, with the advertiser, to study the demographic population (Google search).

This service is clear about the different types of TV ads. In addition to the simple user interface, including the TV guide for Google in the market and find someone who can help you. In fact, Desai said, the plan, advertisers are not advertising on television, and in addition to the specific network in the U.S. are usually not very grateful.
