摘要： Methods, systems, transmitters, receivers, network elements and software applications in a system for acknowledging the reception of sets of data objects, wherein one or more transmitters transmit one or more sets of data objects within respective point-to-multipoint transmission sessions to a plurality of receivers, and wherein repair requests and/or delivery verification reports are transmitted by at least one of said receivers to network elements within point-to-point transmission sessions. Different back-off times are assigned for delivery verification reports and repair requests, at least two delivery verification reports of one receiver are jointly transmitted within one point-to-point transmission session, and a delivery verification report is transmitted after a completed repair session within the same point-to-point transmission session used by the repair session. Furthermore, a minimum set of parameters to be sent in delivery verification reports is shown.

摘要： To support a forward error correction scheme, in which a code of the forward error correction scheme is employed at a transmitting end for encoding data for a transmission to a receiving end, the transmitting end compresses at least one binary parity check matrix associated to the employed code of the forward error correction scheme. The transmitting end then provides the compressed binary parity check matrix for a transmission to the receiving end. The receiving end receives the compressed binary parity check matrix and decompresses it for use in a forward error correction based on encoded data received from the transmitting end.

摘要： A water-saving diffuser for which a user perceives a relatively higher flow rate than the actual flow rate includes a lower chamber portion housing a distributor disk therein, and an accelerator portion attached to the lower chamber portion, the accelerator portion having a plurality of apertures for producing a multiple-stream output from the water-saving diffuser. A central aperture of the distributor disk can be custom-tailored to produce a specific flow rate for a given water supply pressure. The water-saving diffuser may be used in a water distribution system to provide a predetermined uniform flow rate to all regions of a single- or multi-story building.
