Abstract: The invention relates to composing a lighting atmosphere from an abstract description for example a lighting atmosphere specified in XML, wherein the lighting atmosphere is generated by several lighting devices, by automatically rendering the desired lighting atmosphere from the abstract description. The abstract description describes the type of light with certain lighting parameters desired at certain semantic locations at certain semantic times. This abstract atmosphere description is automatically transferred to a specific instance of a lighting system (14, 16, 18). The invention has the main advantage that it allows to create light scenes and lighting atmospheres at a high level of abstraction without requiring the definition of a lighting atmosphere or scene by setting the intensity, color, etc. for single lighting units or devices which can be very time consuming and cumbersome, particularly with large and complex lighting systems comprising many lighting devices.

Abstract: A short-range ad-hoc network (20) of wireless medical devices (22, 24, 26, 28) intercommunicating by a short-range wireless technology are synchronized with official date and time information provided by a time server (70) residing in a medical infrastructure network (32). A time-control device (28, 66) synchronizes its clock (60?, 60?) with the time server. A selected wireless medical device (22) of the wireless shortrange network (20) wirelessly connects with the time control device using the short-range wireless communication protocol and synchronizes a clock (60) of the selected wireless medical device with the clock of the time-control device. The latter wireless connecting and the synchronizing is repeated to synchronize the clocks of each wireless medical device of the short-range network.
