Abstract: A ski which when it is flat on a horizontal plane, and loaded at its waist in such a way that the edges touch said horizontal plane at the waist, has a side cut extending between the front and rear contact lines; when it is pivoted around its longitudinal axis and tilted by a non-zero angle ? relative to said horizontal plane, and loaded at its waist in such a way that one of the edges touches said plane at the waist, has a side cut extending between two end contact points, front and rear respectively wherein for a tilt (?) equal to 35°, the ratio of the distance (D?) separating the front end contact point and the front contact line, related to the distance (D) separating the mid-point (9) of the shoe and the front contact line, is more than 12%.

Abstract: A method for debugging the program of operational software of an onboard system, including flagging the program by positioning flags along an execution path for dividing the aforementioned execution path into adjacent functional intervals; normal execution of the program; acquiring an execution condition of the program by flag condition vectors; when an error is detected, searching a faulty functional interval based on the flag condition vectors, reverse execution of the program in the aforementioned faulty functional interval, and determination and correction of the error.

Abstract: A gliding board, including a gliding surface that terminates in at least one raised end, the end including a peripheral zone and a central zone. The peripheral zone extends from the side of the board toward the central zone the end. This peripheral zone has a thickness, which is less than that of the central zone of the end. The peripheral zone connects to the central zone by a discontinuity that forms an inflexion. The width of the peripheral zone, measured perpendicularly to the side of the board, increases from the beginning of the end to the highest point of the end.

Abstract: A snow gliding board (1) comprises, in particular, an upper surface consisting of an upper decorative and protective element (16) having a recess in which an insert (21, 22, 23) is fitted. The insert (21, 22, 23) comprises at least one first part made of an elastomer material (24) juxtaposed on the upper surface with at least one second part made of a metallic material (26).

Abstract: A ski includes a base plate (2) and a raised, central platform (3). A front supplemental element (6a) is removably attached to a front end of the platform and has a pair of longitudinal arms (60, 61) extending forward along a top surface of the base plate. Similarly, a rear supplemental element (6b) is removably attached to the rear of the platform and has a pair of longitudinal arms (62, 63) which extend slidably along the top surface of the base plate. The supplemental elements are removably attached using a tongue (8a, 8b) and slot (9a, 9b) arrangement and a latch (10, 11, 100). A visual indicator (11, 12; 15, 16) indicates when the supplemental element is properly connected. The supplemental elements include a basic structure (600) with supplemental reinforcing elements (601) removably attached to the undersides of the longitudinal arms.

Abstract: A board (1) for sliding on snow such as a ski, a monoski or a snowboard, with vertical plane of general symmetry (P), comprising a principal part, known as body or base (2), having the shape of an elongated beam having its own thickness distribution, contour, width and stiffness, and can be of any type of structure, and which includes a central zone known as of the waist (7) extended towards the front by a front part (8) raised at its end to form a tip (6), and towards the rear by a rear part (9) terminating in a tail (6?), including at least two supplemental elements (10) extending towards the front at least on the front part, to extend the zone of the waist, said supplemental elements including two longitudinal side arms (10a, 10b) disposed laterally relative to the plane “P”, said longitudinal side arms constituting at least a dynamic means for recall of the base, characterized in that the side arms are connected by a transverse connector (11) including a part independent of the side arms.

Abstract: A ski, monoski, or snowboard includes a base plate (2) with a platform (3) mounted to its central portion to receiving bindings for binding a skier's boot to the platform. A set of four longitudinal elements (40, 41, 42, 43) have one end (40a, 41a, 42a, 43a) which is removably attached to the platform, a second end (40b, 41b, 42b, 43b) which engages a forward or rearward portion of the base plate (2), space and a bridge (40c, 41c, 42c, 43c) between the first and second ends. The bridge is prestressed in order to augment the pressure applied by the boot during skiing to forward and rearward portions of the base plate and to provide a dynamic means of recall for returning the base plate toward a home position.

Abstract: A gliding board (1), including a gliding surface (4) that terminates in at least one raised end (2), said end (2) including a peripheral zone (5) and a central zone (6), the peripheral zone (5) extending from the side (9) of the board toward the central zone (6) of said end, this peripheral zone (5) having a thickness (e1) which is less than that (e2) of the central zone (6) of the end and being connecting to the latter by a discontinuity (7) that forms an inflexion, wherein the width (d) of the peripheral zone (5), measured perpendicularly to the side (9) of the board, increases from the beginning of the end as far as the highest point (12) of the end.
