Today, most computer and consumer electronic devices require wires to record, play or exchange data. UWB (Ultra Wide Band) eliminates the need for such wires freeing people to perform activities such as remotely connecting their mobile PC to a printer, streaming audio from an MP3 player to speakers, or wirelessly transferring digital pictures to a photo print kiosk.

Tel Aviv-based Wisair develops UWB chipsets that facilitate the production of low cost, low power, and high bit-rate communica

The sheer number and variety of security protocols for Internet applications under development makes it difficult to be sure that any one protocol is 100 per cent secure from attack. Now an automated tool can systematically validate these security-sensitive protocols and applications.

“The AVISPA software tool enables a security protocol designer to input the protocol and the language he/she wishes to use, then feeds back information on this protocol including any known bugs or

The new technology developed by VTT, Technical Research Centre of Finland makes it possible to identify the user based on her or his physical movements such as walking style. This feature prevents unauthorised use of portable devices such as laptops or mobile phones. In the future, credit cards may also verify user’s identify based on their physical movements before approval of payment transactions.

For the user the new identification system offers the advantages of increased se

Metal detectors currently used for screening aircraft passengers could soon be supplanted by novel millimetre-wave cameras, able to detect even non-metallic concealed objects. The new system, named after a Brazilian bat, is based on technology developed for ESA spacecraft. Tadar is being demonstrated at this week’s Inter Airport Europe Exhibition in Munich.

Conventional metal detectors, such as those used to check passengers at airports, are limited in that they can on

Currently, the density of transistors that electronic devices now allow is such that the integration of complete digital systems in a single integrated circuit is now possible. With the aim of reducing the period of design and development and enabling the tackling of these kinds of designs possible, these are made up of a base of modules or cores. Given their complexity, these modules often include one or more processors, whereby, in these cases, multi-processor systems are possible.

Many vision systems require text recognition captured at very high speed: vehicle registration identification devices, scanners, etc. Current technology enables the use of complex image pre-processing systems to enhance reading characteristics. This PhD thesis puts forward two binarisation algorithms that are suitable for high-precision applications in optical character reading (OCR). The binarisation of a digital image involves the conversion of the digital image into a black and white one in su
