Abstract: A separator for a crop harvester configured to harvest sugarcane. The separator includes an extractor body that defines a chamber, the chamber extending through the extractor body and is in fluid communication with a cavity of a fan housing. The extractor body can generally define an inlet opening of the chamber, the inlet opening positioned to allow chopped billets and crop residue that are outputted from a chopper assembly to enter into the chamber. The inlet opening has a non-round, or non-circular configuration and/or cross sectional shape. Further, the inlet opening can have a width similar to a material flow width of the chopped billets and crop residue being outputted from the chopper assembly. Such a configuration can eliminate dead zones with respect to air flow that is to pull the chopped crop materials into the chamber and/or to separate crop residue from the chopped billets.

Abstract: Disclosed is a method and apparatus for crossbar arbitration. In one embodiment, the crossbar arbitration includes a memory, a plurality of functional units that transfer data to and from the memory, a crossbar unit that provides a data path from each unit to the memory, and an arbitration unit that monitors data traffic generated by each functional unit through the crossbar unit and assigns a priority to each functional unit based on the data traffic. In another embodiment, the crossbar arbitration includes a method for data transfer arbitration including monitoring data transfers for a plurality of devices, and assigning a priority to each device corresponding to the amount of data transfers generated by the device.

Abstract: A system is described having a network, a bus and an interface coupling the network to the bus. A host is coupled to the network and executes software to generate packets for communication on the network. A bus device is coupled to the bus. The interface and host coordinate to transport bus device packets between the host and the bus device via tunneling over the network.

Abstract: A floor for a basketball court or the like assembled from a plurality of separate floor sections arranged in staggered rows with each section including a plurality of spaced apart sleepers, a subfloor secured to the sleepers, and a wood strip flooring layer secured to the subfloor. Abutting edges of adjoining floor sections are reinforced by tongues and complementary edge pockets mounted on respective abutting edges of adjoining sections. The edge pockets may be formed by recessing the subfloor inwardly of outer edges of the sleepers and the flooring layer. A similar edge pocket may be formed on the adjoining floor section that the tongue is received into. Each tongue is preferably fabricated of a tough, non-marring polymeric material such as ultra-high molecular weight plastic. Alternatively, a similar tongue and pocket arrangement may be formed by mounting a tongue and bracket set on the subfloors of adjoining floor sections.

Abstract: A portable activity floor comprised of a plurality of separate panels that can be readily and selectively interlocked together into a finalized configuration. Each panel has an underlayment providing a core with spaced stringers fastened to the underside thereof. Elongated finishing strips mounted on the upper surface of the underlayment form the outer surface of the panel. In one type of floor assembly, alternate strips are longer than their adjacent strips at the inner side of each panel to form laterally spaced interlock fingers. A pair of hinge members pivotally connects adjacent panels to one another and allows them to be relatively pivoted on a fixed axis with finger interlock alignment accuracy from an initial connected position to a fully assembled position in which the fingers of the finishing strips closely mesh and interlock. Further, the hinge members when connected prevent lateral movement of adjacent panels.

Abstract: A method and apparatus for generating a check sum and a syndrome for detecting errors in a series of bytes comprising a plurality of stages, each stage comprising a plurality of networks of exclusive OR gates, a memory and an exclusive OR gate for exclusively ORing the outputs of the networks resulting from a byte transmitted therethrough with the results stored in a memory in a previous stage due to a previous byte. Each of the stages and the networks therein correspond to a term in a Reed-Solomon polynomial. Except for differences in the number and construction of the networks in each stage, each of the stages are substantially identical and can be selectively used for detecting single and double burst errors.

Abstract: A method and apparatus for transferring data between a disk and a CPU is disclosed comprising a pair of toggling header buffers and a pair of toggling data buffers. In operation, data is transferred between a sector on a disk and one of the data buffers under the control of one of the header buffers. While the data in the header buffer is being transferred between the data buffer and a CPU, data is transferred between an adjacent sector on the disk and the other data buffer under the control of the other header buffer. The rate of transfer of data between the data buffer and the CPU is higher than the rate of transfer of the data between the disk and the other data buffer. This provides sufficient time to check the data transferred from and to the CPU for errors and to address a new sector on the disk prior to the completion of the data transfer of the previous sector between the disk and the data buffer.

Abstract: A method and apparatus for reading data from a disk having missing or unreadable field address marks. Expected address marks are searched for within a time window which is generated using a counter. When an expected address mark is generated at any time within the time window, the counter is set or reset to generate another time window within which the next address mark is expected to occur. By starting or restarting the counter each time an expected address mark is detected the effects of variations in spindle speed which occur prior to the detection of the address mark are eliminated, thus increasing the probability that readable address marks will be detected within a time window.
