  • Publication number: 20240125758
    Abstract: A method of indicating a characteristic of a soil sample of a field includes measuring a co-factor in the soil sample and using the co-factor to place the soil sample in a soil sample group. The characteristic of the soil sample is measured and then is scaled based on the soil sample group. The scaled measure is displayed to better represent the characteristic of the soil sample relative to soil samples of the sample group.

  • Patent number: 9037768
    Abstract: Embodiments of the present invention are directed to methods for virtualizing interrupt modes on behalf of interrupt-generating devices, including I/O-device controllers, so that newer interrupt-generating devices that lack older interrupt modes can be used in systems that continue to rely on older interrupt modes. In one embodiment of the present invention, a PCIe switch or PCIe-based host bridge is modified, or a new component introduced, to provide an interrupt-mode virtualizing function, or virtual interrupt-mode interface, that provides a virtual interrupt mode on behalf of interrupt-generating devices, such as I/O-device controllers, to operating systems, BIOS layers, and other components that communicate with the I/O-device controllers.

  • Patent number: 8626976
    Abstract: A method and apparatus for host enumeration process. One embodiment of the method provides a bit to indicate to the host whether enumeration process should start or continue. The bit may be set when the shared resource process has been successfully completed, or the bit may be set if too much time has elapsed since the shared resource process has started, or the bit may be set if too much time has elapsed before the shared resource process is started, or the bit may be set if the shared resource process has not been performed successfully, or the bit may be set if the port is open and it is unnecessary to perform the shared resource process.

  • Patent number: 8423698
    Abstract: Embodiments include methods, apparatus, and systems for converting resets in a shared I/O system. One embodiment includes a method that propagates a first type of reset from a host computer to a multi-function device that shares I/O operations with other hosts. The first type of reset is converted to a second type of reset to prevent the host from resetting functions bound to the other hosts at the multi-function device.

  • Patent number: 8174977
    Abstract: A network node within a network includes a first receive buffer, first buffer management, a second receive buffer and second buffer management. The first buffer management performs link level credit based flow control for network packets that the first buffer management places in the first receive buffer. The second buffer management performs end-to-end credit based flow control for network packets that the second buffer management receives from the first receive buffer and processes before placing data in the second receive buffer.

  • Patent number: 8019910
    Abstract: A computer-executed method for controlling transaction flow in a network comprises communicating transaction packets among a plurality of devices in a network fabric and subdividing a memory into a plurality of memory segments for storing received transaction cycles according to transaction packet type comprising posted, non-posted, and completion cycles. A plurality of transaction cycles are received in the memory segment plurality at a target device and transaction cycle priority is allocated according to transaction packet type wherein posted cycles have highest priority. Cycles are retrieved from the memory segment plurality in an order determined by priority.
