  • Patent number: 6493854
    Abstract: A method of inserting repeaters into a network to improve timing characteristics of the network. Extraction and timing tools provide an RC network description and a slack report describing electrical and timing characteristics of a network. The timing characteristics include required arrival times of a signal generated at a source to each of the sinks of the network. A maximum slew rate is also defined at each of the sinks. Initial candidate locations for insertion of repeaters is determined. For a given set of legal repeater sizes, one or more sets of midvalue repeater sizes are determined which are used in successive approximation to identify actual repeater sizes to be considered at each of the candidate locations. At each candidate location, capacitance, required arrival time, and slew rate value (c, q, s) are determined in a bottom-up procedure.

  • Patent number: 6242034
    Abstract: In the process of producing corn-based pellets, preconditioner steam and water addition, as well as extruder water or screw configuration and RPM, can be manipulated to precisely control the cook level, gelatinization, and moisture level of the meal during processing, and level of defects despite minor variation in the characteristics of the corn flour. Specifically, the preconditioner added steam-to-water ratio can be manipulated to effect cook, hydration, and partial gelatinization of the meal. In the extruder, lower extruder rotational speeds increase the residence time and increases cook. With the increase in residence time the volume of bed pack in the extruder increases. This can be reversed by adding water directly into the extruder, thereby decreasing the viscosity of the meal in the extruder. Product bulk density is changed by increasing and decreasing cook of the meal.
