  • Port adapter for high-bandwidth bus
    Patent number: 7433988
    Abstract: A port adapter for connecting zero or more network interfaces to a host system having a SPI-4 bus is disclosed. The port adapter comprises zero or more network interfaces; a SPI-4 bus coupled to a host system to provide a communication channel between the host and the network interfaces; a control bus coupled to the host system for controlling and monitoring the port adapter; and interface logic that interfaces the SPI-4 bus and the control bus to the network interfaces. Methods are provided for selecting and using one of a small plurality of different packet formats for various networking technologies, so that the port adapter can hide details of the technology that it handles from the host system, and for operating the host system's SPI-4 bus at one of several speeds based on bandwidth requirements of the port adapter.
    Type: Grant

  • Rumen and other stomach chamber bypass nutrients and methods of fabrication
    Patent number: 5093128
    Abstract: A stomach chamber bypass nutrient comprises a beadlet fabricated in two steps having two regions, a first region having the desired nutrient and a second region including fats and calcium based compounds. The nutrient includes lysine, methionine, tryptothane, protein harmones, vitamins and other nutrients in amounts of from 36% to 59%. The nutrient is fabricated by forming in a first step the nutrient in a beadlet form, and in a second step coating the nutrient beadlet with the second region.
