    • 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.
    • 本公开公开了具有一组集成传感器的滑雪杖,该集合传感器支持由滑雪者消耗的力的计算。 传感器包括嵌入滑雪杖手柄中的计算机处理器和连接到处理器的力传感器,用于感测安装在滑雪橇上的轴向力。 为了计算滑雪者在平行于滑雪者移动的表面的方向上切向施加的力,需要检测在施加的力期间极部分处于的角度,并且这可以通过各种传感器来实现,一个 非限制性示例是集成在手柄中的计算机处理器中的IMU传感器。 为了计算滑雪者输出的功率,包括用于确定速度的传感器(例如,无线连接到滑雪杖传感器和硬件的移动设备的GPS)以及适合于确定地形坡度的传感器。 在一个示例性实施例中,通过假设滑雪杖相对于地面的恒定角度并且使用滑雪杖杆的取向的变化来确定并映射相应的地形变化来确定地形坡度。 可以使用已知的速度,地形坡度,滑雪杖相对于重力的方位以及轴向极力来计算依赖于时间的幂。
