    摘要: The present invention provides a conversion method for converting numeric multi-dimensional database dimension members to textual representations. The conversion is specifically designed to enable the textual representations of the numeric dimension members to be properly sorted and converted back into numeric representations with accuracy. All numeric and date data is transformed during conversion, such that the textual representation of the numeric and date data is properly sorted as a text string, in the same order as it would be sorted as a number. The present invention also provides a means for accurate reverse-conversion (i.e., from textual representation to numeric representation) by first converting into text the information necessary to support the precision required by the relevant convention of the numeric representation. The present invention also provides a convention for determining the data type of the textual representations of values of various data types. The textual representation of mixed types is configured so that the sort order of different data types and the text string for numeric types will sort by value independent of the numeric data-types.

    摘要: The invention monitors the driving range and tracks golf balls from users at the driving range and informs those users of characteristics such as driving distance. A solid state camera images the range, and preferably one or more tee-off positions, and collects frames of image data to track a ball's motion through space. Simulation routines augment that track and assist in isolating the start location as well as where the ball lands, or would have landed had it not been obstructed (e.g., by a net). Preferably, the invention also determines the ball's position in 3-D to increase the accuracy. In one technique, two or more solid state cameras are used, and synchronized, to specify stereoscopic imaging. In another technique, the ball's energy or physical extent is used to determine an absolute distance between the camera and the ball. A computer at the club house monitors the entire system and further manages a network including an array of displays at the several tee off positions. The computer thus sends information such as distance to the several users via the network.

    摘要: A conversion method for converting numeric multi-dimensional database members to textual representations may be provided. The conversion may allow textual representations for the numeric dimension members to be sorted and converted back into numeric representations with accuracy. All numeric and date data may be transformed during conversion, such that the textual representation of the numeric and date data is properly sorted as a text string, in the same order as it would be sorted as a number. Accurate reverse-conversion (i.e., from textual representation to numeric representation) may also be provided. The reverse-conversion may include converting into text, information that may be necessary to support a precision required by the relevant convention of the numeric representation and a convention for determining the data type of the textual representations of values. The textual representation may be configured to sort by value independent of the numeric data-types.
