  • Patent number: 6397287
    Abstract: A network adapter is provided that controls the transfer of data between a host computer and a network medium in a manner which optimizes the amount of data transferred between the host computer and the buffer of the network adapter during a contemporaneous transfer of data between the network medium and the buffer. The network adapter optimizes the data transfer by dynamically determining when to make a bus request such that the buffer is capable of transferring a data packet of a particular target burst size at the end of an estimated latency period. The network adapter includes a buffer memory that transfers data between the host computer and the network medium and a buffer control logic that generates a first buffer data signal in response to the amount of data in the buffer memory.

  • Patent number: 5846472
    Abstract: A method and apparatus for distributing melt through three level stack molds. According to the method a crossover manifold is provided between adjacent mold levels of the stack mold, the crossover manifold having a plenum generally coaxial with a mold axis. Melt is introduced into the plenum through an inlet passage and distributed from the plenum to respective nozzle arrays through a separate outlet conduit associated with each mold level. The apparatus includes a crossover manifold mounted between first and second mold levels and having a plenum generally coaxial with the mold axis. An inlet conduit fluidly communicates with the plenum and an injection head to provide a melt path from the injection head into the plenum. A separate outlet conduit is provided for each mold level.
