    摘要: A method and system for reducing the time required for execution of the dynamic timing simulation for a logic simulator. For a logic circuit simulator having a compilation phase and a runtime phase, a delay assessment is performed during the compilation phase in order to identify storage elements that are exempt from possible timing violations at runtime. The runtime timing checks are removed from the exempt storage elements, thereby reducing the runtime calculation effort. Additionally, combinational portions of the circuit that drive the exempt storage elements are examined for element delays that can be effectively eliminated (e.g., zero delayed) from the runtime calculations, thereby providing a further reduction in the computational overhead via the use of cycle based simulation for these.

    摘要: Described is a technology by which a relay is coupled (e.g., by a wire) to a network and (e.g., by a wireless link) to an endpoint. Incoming data packets directed towards the endpoint are processed by the relay according to an error correction scheme, such as one that replicates packets. The reprocessed packets, which in general are more robust against packet loss, are then sent to the endpoint. For outgoing data packets received from the endpoint, the relay reprocesses the outgoing packets based upon the error correction scheme, such as to remove redundant packets before transmitting them to the network over the wire. Also described are various error correction schemes, and various types of computing devices that may be used as relays. The relay may be built into the network infrastructure, and/or a directory service may be employed to automatically find a suitable relay node for an endpoint device.

    摘要: A papermaking fabric having a top layer and a bottom layer of interwoven machine direction (MD) yarns and cross-machine direction (CD) yarns bound together with warp binder yarns. At least some of the CD yarns are made of a material which generates a strong contractive force when returned to room temperature after heat-setting (annealing under MD tension). These CD yarns are positioned such that the strong contractive force offsets tension forces generated when the fabric is placed under load and which typically result in an edge curl. An exemplary material for these CD yarns is polybutylene terephthalate (PBT).
