Abstract: A method for delivering multicast communications over an IEEE 802.11 compliant network is provided. The method comprises transmitting a data stream to a plurality of receivers from a transmitter over respective network links as a multicast communication, selecting a receiver from the plurality of receivers; receiving a feedback signal from the selected receiver at a selected point in time; and adjusting transmission of the data stream in dependence upon the received feedback signal.

Abstract: The invention relates to a network comprising a plurality of network nodes. At least part of the network nodes are directly intercoupled via at least one star node. The star node contains a plurality of star interfaces which are assigned to at least one network node. A star interface is provided for transferring a message from the assigned network node to the other star interfaces or from another star interface to at least one of the assigned network nodes always in dependence on a pilot signal.

Abstract: The invention relates to a network comprising a plurality of intercoupled network nodes. Controlled by a bus guardian the network nodes transmit messages during a respectively assigned time slot and receive messages from other network nodes outside this time slot. Each network node comprises a test signal generator which delivers a test signal outside the respectively assigned time slot, and includes a test signal detector which detects outside the respective time slot, after receiving a test signal from at least another network node, that there is a defective circuit portion in the assigned network node and/or in at least another network node.

Abstract: The distance computation represents a central, constantly recurrent task in sample and speech recognition. It is used in speech recognition as a degree of similarity between a part of a speech utterance and a speech reference. In picture processing and sample recognition, it is used for data compression. The distance computation requires the longest computation time so that a reduction of the computation time results in a considerable efficiency improvement. A reduction of the computation time is achieved by the integration of the distance computation in a memory module in which particularly the reference data are stored. Due to this integration, the other components of the overall system are relieved of this constantly recurrent task and are available for more complex processes in this period of time. This integration makes the distance computation essentially shorter because the communication between memory sections and computation unit takes place directly without utilizing a busy system.

Abstract: The distance computation represents a central, constantly recurrent task in sample and speech recognition. It is used in speech recognition as a degree of similarity between a part of a speech utterance and a speech reference. In picture processing and sample recognition, it is used for data compression (MPEG). The distance computation requires the longest computation time so that a reduction of the computation time results in a considerable efficiency improvement. A reduction of the computation time is achieved by the integration of the distance computation in a memory module (1) in which particularly the reference data are stored. Due to this integration, the other components (2, 3, 4) of the overall system are relieved of this constantly recurrent task and are available for more complex processes in this period of time.
