    摘要: A method for temporal trend detection employing non-parametric techniques. A set of discrete data is provided and a rank is assigned to the data based on both sensitivity and severity of the data. The method statistically ranks the ranked data by categorizing the data in bins defined by an average positional ranking that identifies the severity of the data for each sensitivity category provided by a bin. The method then clusters the statistically ranked data that has been categorized by average positional ranking so as to detect changes in the data. Clustering the statistically ranked data can include using a multi-nominal hypothesis testing procedure. The method then identifies trends in the data based on the detected changes.

    摘要: A method and system for acknowledging multiple frames in a communication network is provided. A receiver detects transmission of frames from a transmitter. The receiver determines a format for an acknowledgment frame comprising multiple bytes, from multiple frame acknowledgment formats for reporting status of reception of the frames by the receiver. The receiver reports the status of reception of the frames by encoding a distance between a number of frames between two successive correctly received frames, between two successive unsuccessfully received frames, between a correctly received frame and a successive unsuccessfully received frame, or between an unsuccessfully received frame and a successive correctly received frame, in the acknowledgment frame. One or more of the frame acknowledgment formats are configured to generate the acknowledgment frame for acknowledging the frames using a decreased number of bytes. The receiver generates the acknowledgment frame in the determined format for acknowledging the frames.

    摘要: Apparatus for measuring the length of a moving elongate element (1), such as a cable, comprises first and second rotative members (2), (3), rotatable by frictional contact with the element. The second member (3) responds to changes in the velocity of the element (1) to a differing extent to that of the first member (2). The rotation of each member is measured by detectors (11), (12), and data fed to a microprocessor (13) which compares the rotation of the two members to give an indication of the amount of slippage between one or both members and the element (1). The slippage is taken into account in determining the length of the moving element. The differing response to changes in velocity can be achieved by the second member (3) being of a different inertia to that of the first member (2). Alternatively the members frictionally contact the element to a different extent.
