  • a micro-processing unit can be provided in each of the boot units and these can communicate directly with each other and with the ear pieces.
  • a gyroscope can be used as an alternative to a pendulum and the gyroscope can detect the degree and direction of movement by measuring the pitch, azimuth and roll of the gyroscope of the ski and/or the like.
  • FIGS 8a, 8b and 9 A further use of the present invention is illustrated in figures 8a, 8b and 9 wherein data relating to a path taken by a professional alpine skier during a race can be determined and analysed.
  • the speed of change of angle of skis from positive to negative can correspond to left and right turns made by the skier.
  • the skier and/or coach may also require information relating to:
  • the movement detection apparatus of the present invention can be used in conjunction with GPS technology.
  • the location on a course when a particular movement was detected can be determined.
  • This data can then be provided in the form of a graph, as shown in figure 9, wherein the horizontal axis in this example represents time in seconds and the vertical axis is provided by a data logger and represents the angle of the skis as determined by the movement detection apparatus.
  • the paths of two skiers (skier 1 and skier 2) taken down a racecourse for each ski (left and right) are recorded and plotted on the graph.
  • the GPS data can be used to plot the path 400 taken by each skier between slalom gates 1 -7, as shown in figures 8a, and a more detailed comparison of the two skiers paths 400, 402 (skier 1 and skier 2 respectively) taken between gates 1 -5, as shown in figure 8b.
  • the graph can then be used to illustrate the difference in the paths and movements taken by the skiers, the angle of tilt of the skis at different locations, the speed at which the skis were tilted, the length of time of tilt of the skis and/or the like.
  • This data can then be used by the skier and/or coach to improve the skier's use and efficiency of the skis and to identify where time is being lost or gained on the racecourse in comparison to other skiers.
  • a further application of the present invention is in assessing alignment (pronation, supination, femoral anti-version and/or the like) of a person or athlete.
  • the present invention can be used to assess the alignment of a skier, which is important since mis-alignment can hinder the skier's ability to balance effectively whilst undertaking turns and/or other manoeuvres . For example, if a skier is 'knock kneed', this can make it difficult for the skier to initiate a parallel turn.
  • the movement detection apparatus can be used to monitor a skier's alignment when moving in a straight line or when balancing on one or both skis. Any adverse movement detected during these simple operations signals that a balance or alignment problem is present.
  • Alignment shims (tapered wedges which can be of varying angles of taper) can then be used to adjust the skier's foot position to determine the effect this has on movement detected.
  • the shim angle can be adjusted until a desired level of movement or no movement outside pre-determined threshold levels is detected by the apparatus of the present invention.
  • the shim angle producing the desired signal or lack of signal can then be used to fine tune the skier's alignment and to allow a custom made footbed, footwear inserts or orthotics to be formed for the user.
  • the present invention provides an easy way in which a user can improve their skiing skills as a result of being informed by the apparatus of the foot movements that have been made.
  • the apparatus of the present invention will be extremely beneficial to most skiers.

Abstract

La présente invention se rapporte à un appareil de détection du mouvement comprenant une unité de détection du mouvement permettant de détecter le mouvement d'une partie ou de plusieurs parties du corps d'un utilisateur, de ses vêtements, de ses chaussures et/ou de son équipement de sport, par exemple, de ses skis ou de ses chaussures de ski. En plus d'une détection simple du mouvement, l'unité de détection de mouvement peut effectuer une identification d'une ou de plusieurs caractéristiques du mouvement détecté. Les informations sont ensuite transmises à l'utilisateur par l'intermédiaire d'un moyen de signalisation ou elles sont transmises à une unité de mémorisation aux fins de leur analyse à un moment ultérieur.
