Abstract: Disclosed herein is a head-up display system includes a motor that has an output shaft that is rotatable about a first axis. A worm gear is connected to and rotatable with the output shaft about the first axis. A cam wheel is rotatable about a second axis and including a plurality of teeth that are meshed with the worm gear to rotate the cam wheel in response to rotation of the worm gear. A mirror is coupled with the cam wheel and moveable in response to rotation of the cam wheel to move a virtual image on a windshield of the vehicle. A lever interconnects the cam wheel and the mirror and provides movement of the mirror in response to rotation of the cam wheel.

Abstract: A display module has a two-phase motor which includes a rotor including N pairs of poles magnetized radially, in alternate directions, N being equal to 3 or 5, and a stator part including at least two W-shaped circuits made from radial pole teeth extending inwards from a peripheral closed belt and including a coil on a central leg of the W, the W-shaped circuits being arranged in such a way that when the central tooth of one of the W-shaped circuits is positioned facing a rotor magnetic transition, at least one central tooth of another W-shaped circuit is positioned facing a rotor magnetic pole. The display module additionally includes at least one specific mechanical interaction between the rotor and the stator, such as angular friction at a force that is substantially constant depending on the speed of the rotor relative to the stator.

Abstract: An indicator module for a dashboard, including an electric motor, a mechanical motion-reduction unit, an output shaft, a housing, and a light source. The electric motor is mechanically and electrically connected to a first surface of a printed circuit and drives a visual indicator about an axis of rotation via the reduction unit and the output shaft through the printed circuit such that the indicator provides visual information beyond a second surface of said printed circuit. The light source is positioned on the first or second surface of the printed circuit sending a light flow toward the axis of rotation. The housing has a light case, which extends beyond the second surface of the printed circuit and which is formed around the axis of rotation of the visual indicator.

Said display module additional includes at least one specific mechanical interaction (between the rotor and the stator, comprising angular friction at a force that is substantially constant depending on the speed of the rotor relative to the stator, and at a value lower than the torque produced by the electromagnetic interaction between the rotor and the stator.
