Abstract: A user interface for a patient monitoring system which is capable of providing a visual representation of patient monitoring data generated by a plurality of different patient monitors. The user interface bi-directionally communicates with the patient monitors in order to obtain the patient monitoring data. Embodiments also provide a patient monitoring system comprising a plurality of patient monitors and at least one user interface for displaying the patient monitoring data generated by said patient monitors. The user interface monitors its own status and provides an output indicating this status.

Abstract: The invention relates to a radio transmission system comprising a plurality of processing layers for the transmission of data packets between various radio appliances in a radio channel. A first functional unit in a physical radio transmission layer analyses the radio channel and determines the quality (QoC) of the radio channel. A second functional unit in a back-up layer controls the access to the radio channel according to the actual quality (QoC) of the radio channel and the priority of the data packets to be transmitted according to the quality (QoS) of the service carried out by the data packets. A third functional unit in a switching layer controls the switching of the data packets. A control unit then releases the data packets for switching by means of the third functional unit only when the quality (QoS) of the service carried out by the data packets corresponds sufficiently with the quality (QoC) of the radio channel determined in the first functional unit.

Abstract: A radio transmission system has an ad-hoc network, which can be used to transmit data packets with a prescribed waveform, for each node a rating device, which rates the quality of the transmission of the data packets via the ad-hoc network, and an orientation channel. The orientation channel is used to transmit the data packets when the rating device has rated the quality of the transmission of the data packets via the ad-hoc network as unsatisfactory.

Abstract: The invention relates to an arrangement for optimizing the data transmission over a bidirectional radio channel. According to the invention, the digital data to be transmitted according to a data transmission protocol is divided into individual data packets in each of two transmitting/receiving stations. In each transmitting/receiving station, the number and/or priority and/or type (e.g. information, control characters, repeat blocks) of the data packets generated by the data transmission protocol of the higher level and transmitted to the respective transmitter of the station is determined (data packet identifications). According to the data packet identifications, the data transmission protocol is then selected in at least one of the stations in accordance with an optimum utilization of the radio channel capacity.
