Abstract
A method for the continuous ranking of a competitor during a race of a slalom skiing type sports discipline includes the following iterative steps: a step of measuring the variation in the lateral angle of the gliding board about a predefined axis, a step of detecting the moment when the angle passes through a predefined value, a step of recording the competitor's run time corresponding to the detected moment, a step of comparing the stored run time with those of the preceding competitors for the corresponding detected moment, and a step of ranking the competitor with respect to the preceding competitors as a function of the run time of each competitor. A ranking system implements the method.

A method for continuous ranking of competitors during a race of a slalom skiing sports discipline along a racing track, a competitor being provided with at least one gliding board, the method comprises the following iterative steps:
- measuring, by a sensor that includes a gyroscope and is arranged on a ski boot of the competitor, a variation in a lateral angle of the gliding board about a predefined axis;
- detecting, by a detector, a moment when the lateral angle passes through a predefined value;
- recording, by processing circuitry communicatively coupled to a plurality of base stations located along the racing track, a run time of the competitor corresponding to the detected moment;
- comparing, by the processing circuitry that is communicatively coupled to the plurality of base stations located along the racing track, the recorded run time with run times of preceding competitors for the corresponding detected moment;
- and
- ranking, by the processing circuitry that is communicatively coupled to the plurality of base stations located along the racing track, the competitor with respect to the preceding competitors as a function of the run time of each competitor.
A system for continuous ranking of competitors during a race of a slalom skiing sports discipline along a racing track, a competitor being provided with at least one gliding board, the system comprising:
- a sensor that includes a gyroscope and is arranged on a ski boot of the competitor, configured to measure a variation in a lateral angle of the gliding board about a predefined axis;
- a detector configured to detect a moment when the lateral angle passes through a predefined value;
- a timer configured to time a run time of the competitor;
- and
- processing circuitry communicatively coupled to a plurality of base stations located along the racing track, the processing circuitry configured to record the run time of the competitor when the processing circuitry receives a detection signal, to compare the run time with run times of preceding competitors for the corresponding detected moment, and to rank the competitor with respect to the preceding competitors as a function of the run time of each competitor.
