  • Patent number: 11019146
    Abstract: A method for execution by a dispersed storage and task (DST) processing unit includes determining a first optimal slice size requirement is determined for a first independent data element (IDE). The first IDE is split into a first plurality of IDEs based on determining the first IDE compares unfavorably to the first optimal slice size requirement. An error coding function is performed on the first plurality of IDEs to produce a set of encoded slices for each of the first plurality of IDEs for transmission to storage units. A subset of additional IDEs are selected to be merged into a merged IDE based on a second optimal slice size requirement, and continuous content of the subset of additional IDEs is concatenated to produce the merged IDE. The error coding function is performed on the merged IDE to produce a second set of encoded slices for transmission to storage units.

  • Patent number: 8314169
    Abstract: A thermoplastic polymer composition that employs a flame retardant formed from a phosphinic compound and organometallic phosphoric compound is provided. The present inventor has discovered that the organometallic phosphoric compound can counteract the tendency of the phosphinic compound to degrade the mechanical properties of the composition when used at certain concentrations. Furthermore, the present inventor has also surprisingly discovered that the organometallic phosphoric compound may itself act as a flame retardant and thus contribute to the overall flammability performance of the composition. Among other things, this allows compositions to be formed with a lower phosphinic content with the same flammability performance.

  • Publication number: 20060251008
    Abstract: An access-point node to a first network cell of a radio access network, to an access-center node and to a radio access network enable local service providers in rural areas to provide mobile telecommunication at low cost for end users. The access-point node of the invention is configured to establish, maintain, and release a local user-data radio channel, which consists of a first local channel section having as endpoints a first terminal device located in the network cell and the access-point node, and of a second local channel section having as endpoints the access-point node and a second terminal device located in the network cell. The access-point node is configured to exchange packetized user data and control data with an assigned superordinate access-center node for establishing, maintaining and releasing communication between the first terminal device and a third terminal device located outside the network cell. Link cost between the radio access network and the core network may be strongly reduced.
