Abstract: 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.

Abstract: A snow gliding board, integrating a structure element incorporated in a raised end of said gliding board, said element having a plurality of hollowed through openings between its upper and lower surfaces, distributed across its surface, wherein said element comprises in said raised end at least one region free of through openings, separating two areas having through openings, the width of said region being greater than the shortest distance between two through openings in the areas separated by said region.

Abstract: A slide board for use on snow has a point of maximum width located beyond the contact line. The board includes a core extending over the greater part of the board, and a plurality of mechanical reinforcement layers lying directly or indirectly on the core, extending inside the board upturn beyond the contact line. The reinforcement layers are inclusive of that part of the board comprising the longitudinal axis. At least one of the reinforcement layers has an extreme longitudinal point offset transversely relative to the longitudinal axis of the board and, in a zone defined between the contact line and the point of maximum width, the reinforcement layer has an overall cross-section which decreases between the contact line and the point of maximum width. The reinforcement layers have extreme longitudinal points offset longitudinally relative to each other.

Abstract: A board for gliding on snow includes a bottom at least partly defined by a base, a top and sides which connect the bottom and top to each other. Part of the top and the sides are part of a visible surface of the board in use. The board also includes a first part of means for reversibly mounting at least one removable decorative mask on said visible surface.

Abstract: A ski, monoski, or snowboard includes a central longitudinal core (7). Variable width side walls (13a, 13b) are connected with sides of the core. Reinforcement layers (8a, 8b, 8c) are connected with upper and lower surfaces of the core and the side walls. A protection and decoration layer (9) is disposed on an upper surface and a sliding layer (10) including a sliding surface (S) and two edges (11a, 11b) are mounted on the lower surface. Each of the variable width side walls includes an inner wall element (13?a, 13?b) and an outer wall element (13?a, 13?b). At least one of the inner and outer wall elements is thicker in selected regions, such as a central, front, and rear region, to enhance the grip of the edges in the selected region.
