Abstract: A joystick biased to return its stick to a neutral position and with compensation of the force applied by the biasing. The joystick has a stick that is moveable in relation to a base at least in rotation around two axes and biasing element mounted between said base and a movable element acting on said stick, tending to return said stick to a neutral position. The joystick further comprises compensator, mounted between the base and the movable element, and applying on the latter a force to compensate at least partially the force applied by the biasing, at least when said stick is located in the vicinity of said neutral position.

Abstract: The invention relates to a camera designed to be mounted on a screen, including an attachment segment (1) and a shooting segment (3), movable in relation to said attachment segment (1). According to the invention, the shooting segment (3) is movable in relation to the attachment segment so as to be able to take up, once the camera is mounted on a screen, at least two positions in relation to this screen (10): a conversation position in which said optical sensor (4) is placed over a portion of a display zone of said screen; a retracted position in which said optical sensor (4) is moved away from said display zone of said screen (10), so as to completely free up said display zone.

Abstract: The invention relates to a mini joystick including a handle which can be moved in relation to a body, in rotation along at least two axes of rotation. According to the invention, such a mini-joystick includes a Hall effect movement detection set including at least one first element interdependent in rotation with said handle and at least one second element fixed in relation to said body, said elements belonging to the group including the sensors and the magnets, delivering at least one item of information regarding the position of said handle, and detection means for detecting at least one push applied onto an upper part of said handle, able to deliver at least one item of control information when a push is applied, whatever the position of said handle in relation to said body.

Abstract: The invention relates to Hall effect joysticks, and accessories incorporating a Hall effect joystick of a smaller scale. The Hall effect joystick includes a handle which can be moved in relation to a base, in rotation along at least two axes. Said rotation is ensured by way of at least one ball joint including two ball joint elements of roughly the same radius, namely a head and a cup, one being able to pivot around the center of the other. A first of said ball joint elements is fixed in relation to said base and features an opening into which penetrates an extension of said handle, and a second of said ball joint elements is attached to said handle. The extension of said handle includes, in proximity to its lower extremity, at least one sensor and/or at least one magnet of a Hall effect movement detection set.
