In order to use Bluetooth wireless technology, a device must be able to interpret certain Bluetooth profiles. The profiles define the possible applications. Bluetooth profiles are general behaviors through which Bluetooth enabled devices communicate with other devices. Bluetooth technology defines a wide range of profiles that describe many different types of use cases. A2DP,AVCTP,AVDTP and AVRCP are Bluetooth protocol stack used by the profile. Advanced Audio Distribution Profile (A2DP) ;A2DP describes how stereo quality audio can be streamed from a media source to a sink. The profile defines two roles of an audio source and sink. A typical usage scenario can be considered as the “walkman” class of media player. The audio source would be the music player and the audio sink is the wireless headset. A2DP defines the protocols and procedures that realize distribution of audio content of high-quality in mono or stereo on ACL channels. The term “advanced audio”, therefore, should be distin...
The first - clockwise - proton beam completed its first circuit of the underground tunnel at just before 0930 GMT. The second - anti-clockwise - proton beam successfully circled the ring after 1400 GMT. The beams have not yet been run continuously. So far, they have been stopped, or "dumped", after just a few circuits.Cern has not yet announced when it plans to carry out the first collisions, but some low-energy collisions could happen in the next few days. This will allow engineers to calibrate instruments, but will not produce data of scientific interest. The vast circular tunnel - the "ring" - which runs under the French-Swiss border contains more than 1,000 cylindrical magnets arranged end-to-end. The magnets are there to steer the proton beam around this 27km-long ring. In order to get both beams to circulate continuously around the LHC, engineers have to "close the orbit". The beams themselves are made up of several "packets" - each about a...
MS Windows 7, the next major release of the world's most popular operating system, goes public in trial form in the next week. A test version of Windows 7 will be available to developers from Thursday, while the public can try it out from 5 May. Microsoft is hoping it can avoid the negative press that surrounded the launch of Vista, the last major Windows release, almost three years ago. Windows 7 has been designed to be compatible with Vista so users do not have to invest in new hardware. A commercial release of Windows 7 is expected in the next nine months.
