    摘要： A user terminal (UT) to transmit small amounts of data, the UT including: a packet including the data, where the packet is less than 128 bytes; a frequency synchronizer to synchronize a transmission frequency of an ASCMA return link connecting the UT with a satellite gateway; and an ASCMA transmitter to transmit, without acquiring timing synchronization with the satellite gateway from the UT, the packet modulated over the synchronized transmission frequency as an ASCMA waveform including a preamble to indicate a start of a transmission. Other embodiments of this aspect include corresponding computer systems, apparatus, and computer programs recorded on one or more computer storage devices, each configured to perform the actions of the methods.

    摘要： A system and method for beamforming includes providing an antenna including feeds, a coverage area including service areas and data streams for each of the service areas; scheduling N data streams of the data streams, selecting a cluster of M feeds from the feeds; computing, with a GBBF processor (ground based beam former), M×N weights; generating M feed excitations by distributing the N data streams per the M×N weights; switching an array to transfer a respective one of the M feed excitations to a respective one of the M feeds; and beamforming, with the M feeds of the antenna, N beams. In the method, the N beams are each focused on a respective service area of each of the N data streams, the M×N weights improve the transmitting into the respective service area of each of the N data streams, and at least one of the N beams includes a portion of a plurality of the M feed excitations.

    摘要： A method is provided for manufacturing a paper or a thermoplastic foil or a vitrimeric foil printable with an inkjet printer for use as a decor paper, respectively a decor foil in a laminate or laminated panel. The method may involve providing a paper layer, respectively a foil. At least one side of the paper layer, respectively of the foil, may be coated with an inkjet receiver coating that includes at least pigment and binder. The inkjet receiver coating may include an ink reactive compound. The papers and foils may be provided with a printed pattern and used as a decor in the panels.

    摘要： A method for using multiple communication paths in a satellite network is disclosed. The method including: initiating a connection request from a first peer to a second peer; providing communication paths between the first peer and the second peer; retrieving a policy corresponding to the communication paths, the first peer and the second peer; receiving a transport metric for at least one of the communication paths; selecting a path from the communication paths based on a connection metric, the transport metric and the policy; and establishing a connection between the first peer and the second peer with the path, wherein at least one of the communication paths is relayed by a satellite.
