Abstract: Conference systems are often installed in plenary halls or meeting rooms, whereby such conference systems typically consist of a central equipment and equipment for the participants of the discussion. The central equipment is usually used to control the conference system and supply power to the participant equipment.

Abstract: Conference systems are used for example in discussions and usually comprise a plurality of delegate units with microphones, whereby in a discussion each discussion participant uses his own delegate unit. Usually the delegate units have a switch or the like, that allows the participant in front of the delegate unit to request, that his microphone is activated, so that the speech of the participant is input in the conference system and amplified by the conference system.

Abstract: Public address systems or other systems for emitting audio signals, like music, speech or announcements, in different locations like supermarkets, schools, universities, and auditoriums are widely known. In one embodiment, invention proposes a system for emitting an audio signal in an environment. The system includes an audio source for providing the audio signal and at least one loudspeaker for emitting the audio signal. The system also includes at least one microphone for receiving an acoustic signal from the environment. The acoustic signal is based on the audio signal and may comprise disturbing components. The system also includes an analyzing module for analyzing the acoustic signal and for providing an intelligibility measure from an objective intelligibility measure method. The intelligibility measure is used as a feedback signal.

Abstract: Public address systems or other systems for emitting audio signals, like music, speech or announcements, in different locations like supermarkets, schools, universities, auditoriums are widely known. These systems usually comprise an audio source, for example a microphone or a recorder, and a plurality of loudspeakers, which are locally distributed in the locations, for emitting the audio signal from the audio source.

Abstract: Conference Systems usually comprise a plurality of delegate units, whereby each delegate unit provides a speaking place for a person attending the Conference. A delegate unit (1) for a Conference System is disclosed with a microphone (4) and a signal means (6, 7, 9) whereby the signal means (9) comprise a possible-to-speak indicator (9) operable to indicate a possible-to-speak Status of the microphone (4), whereby the microphone is ready to be activated by a user of the delegate unit (1), thus indicating the user floor status.

Abstract: The invention proposes a method for power-saving operation of communication terminals in a communication system, particularly in a wireless communication system, where a central station in the communication system takes a user input as a basis for prompting a change in an operating state of the communication terminals in the communication system which is characterized by the power consumption. Preferably, the method is used in wireless conference systems, with the communication terminal being in the form of a participant unit and/or chairman unit.
