摘要：
The present disclosure discloses a ski pole having a set of integrated sensors that support the calculation of force expended by a skier. The sensors include a computer processor embedded in the ski pole handle and a force sensor, connected to the processor, for sensing the axial force which is mounted on the ski. In order to calculate the force applied tangentially by the skier in the direction parallel to the surface over which the skier is moving, the angle that the pole section is at during applied force needs to be detected and this may be achieved with various sensors, one non-limiting example being IMU sensors integrated in the computer processor in the handle. In order to calculate the power output by the skier, there is included a sensor for determining speed (e.g. a GPS of a mobile device wirelessly connected to the ski pole sensors and hardware), and sensors suitable for determining the terrain slope. In one example embodiment, the terrain slope is determined by assuming a constant angle of the ski pole relative to the ground, and using the change in orientation of the ski pole to determine and map the corresponding change in terrain. The known speed, terrain slope, orientation of the ski pole relative to gravity, and axial pole force may be employed to compute time- dependent power.
