The invention relates to field of connected sport and specifically a method for quantifying sporting activity implemented by a communication system including: a proximity beacon associated with sports equipment, measuring equipment and a communication node, the method including: (a) communicating between the measuring equipment and the beacon in order to recover a first data packet comprising an identifier relating to a sporting activity associated with the sports equipment; (b) transmitting, to the node, a second data packet comprising the identifier; (c) at the node, determining parameterisation data of the measuring equipment according to the identifier; (d) transmitting, to the measuring equipment, a third data packetcomprising said parameterisation data; and (e) at the parameterised measuring equipment, quantifying the sporting activity.

Method for quantifying a sporting activity

A system for analysis of the performance in use of a sliding board includes a database storing baseline performance; a sensor sensitive to the deformations of said sliding board; and a monitoring body. The monitoring body determines the performance in use based on measurements from the sensor; and compares the performance in use with the baseline performance. The sensor is secured to the sliding board and has at least one piezoelectric element secured to the sliding board and configured to generate electric energy during the deformations of the sliding board; and an electronic processing circuit, powered exclusively by the electric energy generated by the at least one piezoelectric element.

System for analysis of the performance in use of a sliding board

A system for analysis of use of a sliding board comprising at least one piezoelectric element configured to be secured to the sliding board and generate electric energy during deformations of the sliding board; and an electronic processing circuit configured for estimating at least one parameter of use of the sliding board and configured to be connected to the sliding board. The electronic processing circuit is powered by the electric energy generated by the at least one piezoelectric element.

Analysis system and associated sliding board

The method involves a step of measurement of a bearing force (Fp) on a pedal () of the pedal set (), different from the useful effort, exerted by the individual during a pedalling cycle, a step of determination of a maximum (max(Fp)) of the bearing force measured during the pedalling cycle (CP), and a step of estimation of a mean useful effort exerted by the individual during said pedalling cycle from the maximum of the bearing force determined and with the aid of a predetermined correlation function between a maximum bearing force during a pedalling cycle and a mean useful effort in said cycle.

Method and a system for estimation of a useful effort provided by an individual during a physical activity consisting in executing an alternating pedalling movement on a pedal device

A bicycle pedal including a tube, assembled to freely rotate around an axis, and a pedal body including at least one first surface on which a cyclist is capable of exerting an effort, the pedal body being connected to the central tube by at least one connecting member including a first portion interposed between the tube and the first surface and fitted with at least one deformation gauge.

A method for energy management in an electrically assisted vehicle includes the steps of determining the quantity of total energy required for a journey and allocating a quantity of electrical energy to the journey and deducing the quantity of human energy required for the journey on the basic thereof, or allocating a quantity of human energy to the journey and deducing the quantity of electrical energy required for the journey on the basis thereof.

Power management in an electrically-assisted vehicle

The invention relates to a power management method for an electrically assisted vehicle, comprising the following steps: a) determining the total amount of power required for a journey; and b) assigning an amount of electric power to the journey and deducing therefrom the amount of human power required for the journey, or assigning an amount of human power to the journey and deducing therefrom the amount of electric power required for the journey.

Power management method for an electrically-assisted vehicle

A method and system for measuring the output power produced in a device having a crankset, includes: measuring the orthogonal force exerted on at least one pedal of the crank; determining the angular velocity of the crank; and deducing the tangential force exerted on the crank and the power, using a pre-established model of the distribution of the force exerted on the actuating member as a function of the angular velocity.
