Digital Pen

This digital pen is a computer invention that transmits writing into digital media.Although touch screen devices represent a movement away from paper, approximately eighty-percent of businesses still use paper based forms.Many professions hand-write their notes, tables, diagrams and drawings instead of using tablets or other devices.The computer pen is comparable to a regular ink pen (even uses refillable ink) that writes on regular paper, except it has an optical reader that records motion, images and coordinates. The recorded data is then transmitted to a computer via a wireless transmitter.You can browse and edit your written notes, diagrams, tables, or drawings.Another useful feature of this computer invention is that hand-written digital files can be easily converted into text fonts for use in word documents or emails.Digital pen technology was first developed by the Swedish inventor and entrepreneur Christer Fåhraues.

Your smartphone can detect cosmic rays

Researchers from University of California have tested that a smart phone camera can detect high energy photons and                                                                                   particles of the sort produced by cosmic rays.

NEW YORK: Can your smart phone detect very high-energy cosmic rays that hit the Earth from space? Yes, say physicists.
Researchers from University of California have tested that a smart phone camera can detect high energy photons and particles of the sort produced by cosmic rays.
Testing with radioactive isotopes of .radium, cobalt, and cesium showed that the detector easily picked up gamma rays.

They also put a phone inside a lead box and showed that they could detect high energy particles.

Finally, researchers took a phone up on a commercial flight and were able to obtain a particle track across the detector.

The project is called CRAYFIS (Cosmic RAYS Found In Smartphones).

When your phone is inactive and plugged in for charging, CRAYFIS monitors the camera, looking for signs of high-energy items striking the detector, arstechnica website reported.

According to researchers, if they can get 1,000 active cell phones within a square kilometer area, they will be able to detect nearly all of the high energy cosmic rays that strike the atmosphere.
