Abstract: A system and method for a time-scalable priority-based scheduler. A flexible scheduling algorithm utilizing variable scheduling durations enables better system capacity utilization. A rate request (408) is transmitted if data arrives in a buffer, data in the buffer exceeds a buffer depth, and sufficient power exists to transmit at the rate requested. A rate assignment (418) responsive to the rate request indicates a scheduled duration and a scheduled rate applicable for the scheduled duration. The scheduled duration is less than or equal to a scheduling period (508). The scheduling period is an interval of time after which a scheduler makes a scheduling decision. The scheduling period is variable and the scheduled duration is variable. The scheduler is preferably applied in a UMTS, CDMA 2000 or HDR-system for reverse link rate scheduling.

Abstract: A pivoting mid-floor section for use in a feeder house in an agricultural combine is located between the transverse drum and the transverse sprocket means. The pivoting mid-floor can move or adjust when a large volume of crop material is fed into the feeder house, while providing support for the conveyor chain along substantially the entire length of travel between the transverse drum and sprocket means, thus reducing the friction on the chain, and preventing the system slow downs that occurred in feeder house systems using a fixed mid-floor. Additionally, replaceable wear-resistant surfaces can be affixed to the runners or guides of the mid- floor to further extend wear life and reduce friction between the chain slats and mid- floor. The friction occurs between the wear pads on the runners or guides and the chain slats, rather than between the chain components and the mid-floor.
