Abstract: A cancelation registry provides a cancelation interface whose implementation registers cancelable items such as synchronous operations, asynchronous operations, type instances, and transactions. Items may be implicitly or explicitly registered with the cancelation registry. A consistent cancelation interface unifies cancelation management for heterogeneous items, and allows cancelation of a group of items with a single invocation of a cancel-registered-items procedure.

Abstract: A data partitioning interface provides procedure headings to create data partitions for processing data elements in parallel, and for obtaining data elements to process, without specifying the organizational structure of a data partitioning. A data partitioning implementation associated with the data partitioning interface provides operations to implement the interface procedures, and may also provide dynamic partitioning to facilitate load balancing.

Abstract: A parallelism policy object provides a control parallelism interface whose implementation evaluates parallelism conditions that are left unspecified in the interface. User-defined and other parallelism policy procedures can make recommendations to a worker program for transitioning between sequential program execution and parallel execution. Parallelizing assistance values obtained at runtime can be used in the parallelism conditions on which the recommendations are based. A consistent parallelization policy can be employed across a range of parallel constructs, and inside recursive procedures.

Abstract: A membership interface provides procedure headings to add and remove elements of a data collection, without specifying the organizational structure of the data collection. A membership implementation associated with the membership interface provides thread-safe operations to implement the interface procedures. A blocking-bounding wrapper on the membership implementation provides blocking and bounding support separately from the thread-safety mechanism.

Abstract: A device is fitted into a well of a one-piece wheel rim so as to prevent a tire fitted onto the rim from rolling off this rim. A process for manufacturing this device is disclosed as is a fitted assembly for a motor vehicle comprising the rim, the cover and the device. The device has a belt having two ends and a catching blocks for connecting the ends together, which is intended to clamp the belt of annular shape around the rim well, and this device is such that the belt includes a plurality of filling elements, spaced apart between the ends, which elements are designed to at least partly fill the well and are connected together via at least one flexible linking element intended to form an annular sector around the well.

Abstract: The present invention relates to a device designed to be fitted into a well of a one-piece wheel rim so as to prevent a tire cover fitted onto said rim from rolling off this rim, to a process for manufacturing this device and to a fitted assembly for a motor vehicle comprising said rim, said cover and said device. A device according to the invention comprises a belt having two ends and a connecting means for connecting said ends together, which means is intended to clamp said belt of annular shape around the rim well, and this device is such that said belt includes a plurality of filling elements, spaced apart between said ends, which elements are designed to at least partly fill said well and are connected together via at least one flexible linking element intended to form an annular sector around said well.

Abstract: A method for sharing tasks, comprising: identifying a covered user, wherein the covered user is assigned one or more tasks; identifying a surrogate user that is associated with the covered user; identifying an unfinished task from the one or more tasks assigned to the covered user; creating a link for the surrogate user to the unfinished task assigned to the covered user; and providing the ability for the surrogate user to access the unfinished task via the link.
