Researchers at the University of Liverpool have shown for the first time that WiFi networks can be infected with a virus that can move through densely populated areas as efficiently as the common cold spreads between humans.
Scientists developed a method of transformation of the usual Wi-Fi equipment in the detector. This wireless equipment is allowing to define situation and even a pose of the user in any place of the apartment. The technology is based on registration of distortions of electromagnetic waves by a human body. The system prototype already passed tests in the three-room apartment and the office room.
Physics used Doppler’s effect in the invention. This phenomenon represents change of frequency of the radiation let out or reflected by a moving body. As the radio waves used in wireless networks, well are reflected from a human body. Their registration with simultaneous measurement of frequency can easily reveal speed.
The Philips company let out tools of the developer for Hue — personal wireless system of lighting. This system started its operation from October 2012. The tools will allow the programmers to create applications for iOS, also will help the producers of devices to produce household appliances supporting the work with system. In spite of the fact that the tools started using only on March 11, some developers had issued programs for Hue before this date. One of such programs, Ambify, forces lamps of Hue to change color of a luminescence in a step to music. Hue includes three LED lamps and the Wi-fi module. By installing the free program, the user can operate the Philips light bulbs from the Smartphone or a tablet. It is possible to change, for example, color and brightness of a luminescence or to include or switch off Philips light bulbs, being outside the apartment. The price of system is $199,95,the price for the additional lamps is $59. By the words of Philips, the life of Philips light bulbs is 15 thousand hours.
The new iPad unveiled Wednesday comes with improvements that may not be readily apparent to the casual observer. It has, as expected, a sharper screen, driven by a faster processing chip that acts as the “brains” of the device. What was more surprising was that the new features mean the tablet computer will be slightly thicker and heavier than the iPad 2, because it needs a larger battery to power the high-resolution screen. Apple gave the new iPad a bunch of new features but no new name. It will be “the iPad” or perhaps “the new iPad”, not “iPad 3” or “iPad HD,” as some had speculated. Prices aren’t changing from the previous models.
In January at CES 2012, ViewSonic will introduce a new 9.7-inch tab, which is likely to compete with the iPad. Model ViewPad 97a has at its disposal a 9.7-inch IPS screen with resolution of 1024 x 768 pixels.
Skype offers all travelling users free Wi-Fi services in more than 50 US airports in the period from December 21 through December 27.
EOS Innovation that hails from France has come up with the E-One remote monitoring robot that is currently in the experimental stage, but is intended to patrol on its own and alert its owner if it detects anything unusual.
NEC Corporation with Hitachi and Mitsubishi Electric Corporation has developed a new technology that allows you to create devices that transmit data via Bluetooth receiver and Wi-Fi, that don’t require the power. Transmitter is powered by energy from radio waves at any frequency.Design feature of the device is that they are considerably reduced in size because they don’t need the batteries.
