Paskins, A. S ir , Radiology plays an important role in the decision-making processes of rheumatologists. At our Trust, hard copies are no longer routinely available. Although concerns exist about the timetable for implementation [ 2 ], eventual widespread use of PACS with integration into an electronic patient record is inevitable. The benefits of a fully digital X-ray storing and reporting system are fairly obvious: images should be quick and easy to retrieve; comparison with old films should be easily facilitated; digital manipulation may aid interpretation for example, by zooming in , images can be easily shown to colleagues at other hospitals or sites; films should not be lost; images can easily be accessed for use as teaching aids; and there are theoretical beneficial long-term cost implications. The aims of this project were to gather structured feedback to present to the local radiology department; to collect information that may be of interest to other rheumatologists not yet using PACS; and to establish local standards for use in a future cross-speciality audit planned within our Trust. A record of the software used at the different NHS Trusts was also recorded.

The communication that occurs in our day-to-day life is in the form of signals. These signals, such as sound signals, generally, are analog in nature. When the communication needs to be established over a distance, then the analog signals are sent through wire, using different techniques for effective transmission. The conventional methods of communication used analog signals for long distance communications, which suffer from many losses such as distortion, interference, and other losses including security breach.

Satellite communication is an electronic communication package placed in an orbit. Its prime objective is to initiate or assist through space. It has made a major contribution to the pattern of international communication. The satellite microwave is basically a microwave relay station in space. It uses a geosynchronous satellite to relay the radio signal transmitted from the ground station.

Stuart Parsons, Arjan M. Boonman, Martin K. Bat researchers currently use a variety of techniques that transform echolocation calls into audible frequencies and allow the spectral content of a signal to be viewed and analyzed. All techniques have limitations and an understanding of how each works and the effect on the signal being analyzed are vital for correct interpretation. The 3 most commonly used techniques for transforming frequencies of a call are heterodyne, frequency division, and time expansion.
