Abstract: A header comprising multiple row elements along a width of the header. The multiple row elements are connected to a frame which is segmented into two peripheral segments and two central segments. Each peripheral segment is connected to an adjacent one of the central segments via a respective distal pivot, and the central segments are interconnected via a central pivot. The distal pivots are arranged to allow a rotation of the peripheral segments with respect to the central segments. The central pivot are arranged to allow a central rotation of the central segments with respect to each other, such that the segments are movable with respect to each other between a folded state and an operating state.

As an example, a data packet retransmission device might be configured to retransmit in response to each retransmission request an amount of data packets depending on the physical layer interleaving delay ID and/or data bit rate DBR.

The wired transmission line testing method first comprises the steps of a first transceiver sending a first known excitation signal over the wired transmission line and subsequently the step of the first transceiver and the second transceiver both generating a first representation of a received signal respectively including reflected or forwarded portions of the known excitation signal and third a processing part deriving at least one physical characteristic of the wired transmission line based on the first representations generated by the first transceiver and the second transceiver.

Abstract: A transmitter device (210) and associated receiver device (211) providing a retransmission scheme for use in communications involving lossy media. The transmitter device (210) receives data packets (201) from a source and adds protection to selected subflows before delivering (203, 206) them to the receiver device (211). The receiver device (211) is able to remove the protection and process (207) the data packets further. The retransmission scheme introduces greater reliability on the lossy medium by restricting the retransmission (208, 209) to a particular link and to selected subflows of traffic in the connection between a source and a destination.
