Abstract: A system for controlling the electric motor of a pedal-assisted bicycle including a pedal-thrust group and a battery. The control system includes a pedal-thrust cadence sensor a pedal-thrust torque sensor, a bicycle acceleration or speed sensor a motor power detecting sensor a closed-loop controller of the torque, a closed-loop controller of the resisting torque and a dividing. The closed-loop controller of the torque is configured to generate a reference motor command signal based on the cyclist torque The closed-loop controller of the resisting torque is configured to generate a reference motor command signal based on the resisting torque. The dividing module is configured to generate a motor reference command signal based on the reference motor command signal based on the cyclist torque, on the reference motor command signal based on the resisting torque, on the effective resisting torque, and based on a reference dividing parameter.

Abstract: A sail system comprising a substantially isosceles-triangle-shaped sail with two booms and an arc-shaped element. The two booms are arranged along substantially equal sides of the sail and articulated to one another with a joint that defines a vertex of the triangle. The arc-shaped element is coupled to a deck of a boat for pivoting about a transverse axis between a raised position and a lowered position on the deck. Each boom has a coupling element on the arc-shaped element, the coupling element being slidable both along the arc-shaped element and along the respective boom.

Abstract: The present invention relates to a method for controlling the propulsion modes of a boat of the type comprising a power controlled motor, a group of sails and a first plurality of sensors of the wind conditions and of the motion conditions of the boat, the method being characterized in that it comprises the steps consisting in detecting a plurality of typical parameters of the wind conditions through the first plurality of sensors, verifying whether the plurality of typical parameters of the wind conditions so detected satisfies a predetermined set of extreme conditions for hoisting or lowering the group of sails, selecting at least one driving mode of the boat selected from a plurality of driving modes of the boat, when the group of sails is hoisted, and controlling the power controlled motor on the basis of the selected driving mode of the boat.

Abstract: The invention concerns a sail system comprising a substantially isosceles-triangle-shaped sail (1; 101), two booms (2, 3; 102, 103), arranged along the substantially equal sides of the sail (1; 101) and articulated to one another at an end with a joint (4; 104) that defines a vertex of the triangle of the sail, and an arc-shaped element (7; 107), which can be coupled to the deck of the boat (A) on which said sail system is foreseen with the two ends pivoted around an axis (20, 120) transverse to the hull of the boat and that is mobile around said axis between a configuration raised from the deck and a configuration lowered onto the deck, in which each boom (2, 3; 102, 103) has a coupling element (5, 6; 105, 106) on said arc-shaped element (7; 107), said coupling element (5, 6; 105, 106) being slidably mounted both along said arc-shaped element (7; 107) and along a section of the respective boom (2, 3; 102, 103), and in which the sail (1; 101) is provided with a further coupling element to the boat (A) on whic
