Some embodiments are directed to an analysis device for board sports, intended to be secured to a board, such as a surfboard or ski, at the interface with the user. The device includes: a force sensor designed to capture one or more forces generated by the user on the board; a position and motion sensor designed to capture the position, speed and acceleration of the board in space; and a processing unit or processor connected to the force sensor and to the position and motion sensor and designed to synchronize and process the data from the sensors.

Device for board sports and associated learning method

In a method for controlling an actuating device of a valve element of an intake system and/or an exhaust gas system of the internal combustion using an actuating variable, a periodic compensation signal is applied, at least intermittently, to the actuating device. The compensation signal generates a periodic counterforce at the valve element which is directed in the opposite direction from the periodic force exerted by the undesired disturbing vibrations of the valve element.
