IXNEA S.r.l.

System (1) for signalling the closing/opening of a door of a vehicle, comprising contact means between said door and said vehicle, said contact means being configured to generate an opening/closing signal of said door with respect to said vehicle, a circuit (2) for converting said opening/closing signal electrically connected to said first pair (3) of wires and suitable for generating a converted opening/closing signal of said door and an electronic control unit (7) configured to receive said converted opening/closing signal and to signal it to a user.

Step (1) of a vehicle (V), comprising a fixed portion (2) adapted to be permanently connected to said vehicle (V), and at least one footboard (3) for supporting a user; first connection means (4) for connecting said at least one support footboard (3) to said fixed portion (2) and second connection means (5) for connecting said fixed portion (2) to said vehicle (V) .

[0001] Robot (1), for collecting balls comprising a frame (2), movement means associated with the frame (2) and configured to move the robot (1) over a corresponding ground surface, a collection unit (3) for collecting balls present on said ground surface, and a storage container (13) for the balls collected by the collection unit (3). [FIG. 1]

Moving system (1), comprising a polygonal threaded bar (2) having a main axis of development (A); a nut (3) configured to engage in screwing with said polygonal threaded bar (2) and move relative to said bar (2) along said axis (A); a platform (6) disposed resting on an upper portion of said nut (3) and moved along said axis (A) by said nut (3) itself, said platform (6) having a gap (61) through which said polygonal bar (2) passes, said gap (61) having a polygonal shape substantially counter-shaped to a polygonal ridge (21) of said threaded polygonal bar (2).

Cutting and coupling method, comprising the steps of providing a first sheet (L1) of resilient material and moving it towards a first coupling area (A1); providing a spring pack (2) and moving it towards said first coupling area (A1); gluing a contact surface of said first sheet (L1) to a first lateral surface (21) of said spring pack (2) and cutting a first portion of said first sheet (L1) glued to said spring pack (2), thereby obtaining a first spar (31).

Cutting and coupling method, comprising the steps of: arranging a first sheet (L1) of resilient material onto a first cutting station (5); arranging a spring pack (2) onto a first bearing plane (P1) adjacent to a first coupling area (A1); cutting a first portion of said first sheet (L1), said first portion defining a first spar (31); moving said first spar (31) towards a first coupling area (A1) adjacent to said first bearing plane (P1); applying a layer of adhesive to at least one of a first lateral surface (21) of said spring pack (2) and said first spar (31) at a contact surface; gluing said first lateral surface (21) of said spring pack (2) to said first spar (31).
