Miniaturized illuminated pointer for instrument cluster
An illuminable pointer assembly for an instrument panel includes a transparent or translucent base, a transparent or translucent pointer blade, and a hub mounted on the base and supporting the pointer blade. The assembly is miniaturized or capable of being miniaturized by integrating reflectors into a lower surface of the pointer blade to internally reflect light propagated upwardly through the base in a lateral direction to uniformly illuminate the pointer blade.

Display device
A display device has a scale in the shape of a circular arc. On an axis driving an indicator axis, a rotatably mounted gear wheel is arranged in a rotatably fixed manner, in the teeth of which the toothing of a wobble gear ring partially engages. The wobble gear ring is mounted about the axis of the rotatably mounted gear wheel such that the wobble gear ring can wobble, is acted upon by spring forces distributed around the periphery of the wobble gear ring in the direction of engagement of the toothing of the wobble gear ring in the teeth of the rotatably mounted gear wheel, and is fixedly connected to a ferromagnetic ring extending in the direction of rotation of the wobble gear ring. At least two pole shoes project through independently energizable coils to the outer circumferential surface of the ferromagnetic ring.

Indicating-needle type meter device
In an indicating-needle type meter device, when starting excitation of a stepping motor, a controller sets the phase of an excitation signal to a predetermined excitation start position and returns the phase of the excitation signal by a predetermined reversal angle such that an indicating-needle rotates in the backward direction, thereby positioning the indicating-needle at a stopper position. Subsequently, the controller advances the phase of the excitation signal by an origin return angle to rotate the indicating-needle in the forward direction to an origin position apart from the stopper position by a predetermined angle, thereby positioning the indicating-needle at the origin position. Here, the origin return angle is an angle obtained by adding a backlash angle, a predetermined positive pre-offset angle, and a positive placing error correction angle set based on a placing error of the indicating-needle with respect to the stopper.
Illuminated pointer instrument for a motor vehicle
A pointer needle for an indication device of a motor vehicle has a transparent optical waveguide that receives light propagating along a direction of propagation at a light-entry side, and emits the light in an emission direction at a light-exit side. The optical waveguide has a scattering side opposite to the light-exit side, the scattering side having steps arranged offset to one another across the propagation direction. When the steps are irradiated by light, the pointer needle provided in the indication device can clearly be perceived in the dark.
