Abstract: An ignition switch and steering lock device for motor vehicles, comprising: a main body; an electronic control circuit provided with input/output interfaces; a locking mechanism; a mechanical actuator, for moving the locking mechanism. The locking mechanism is mobile between a locked position in which its action blocks the vehicle steering in a fixed orientation relative to the frame, and an unlocked position in which the elements do not block the rotation of the steering relative to the frame. The locking mechanism can be moved into the locked position only at a minimum steering lock orientation. The device further comprises at least one unlocked position sensor to determine the position of the locking mechanism and at least one steering orientation sensor to determine the orientation of the steering.

Abstract: A cap for fuel tanks, in particular for motorcycles, comprising: an annular body, predisposed to be fixed stably on board an access opening of a tank, which access opening delimits a through-opening through which the tank can be accessed; a lid, constrained rotatably to the annular body, which is rotatable between an open position, in which the through-opening can be accessed, and a closed position, in which the through-opening cannot be accessed; a closure device, predisposed to block the lid in the closed position.

Abstract: A group for measuring physical parameters relating to a state of a tire, comprising: an internal panel comprising at least a sensor, means for fixing for removably connecting the internal panel to a groove of a rim. The means for fixing comprise: a support element, solidly associable to the rim, and means for connecting predisposed to realize a reversible elastic coupling between the support element and the internal panel.

Abstract: An ignition switch and steering lock device for motor vehicles, comprising: a main body; an electronic control circuit provided with input/output interfaces; means for locking; a mechanical actuator, for moving the means for locking. The means for locking are mobile between a locked position in which their action blocks the vehicle steering in a fixed orientation relative to the frame, and an unlocked position in which said elements do not block the rotation of the steering relative to the frame. The means for locking can be moved into the locked position only at a minimum steering lock orientation. The device further comprises at least one unlocked position sensor to determine the position of the means for locking and at least one steering orientation sensor to determine the orientation of the steering.
