Abstract: Disclosed herein is a mechanical instrument cluster with a lighted pointer. The light pointer is driven by either a shaft or shaft-less stepper motor, and includes applique layers that are viewable when lighted. The pointers disclosed herein are capable of illuminating with at least two colors, with a single light emitting diode (LED) with multiple colors.

Abstract: An analog gauge includes a pointer attached to a post and overlying and rotating relative to a substrate to indicate a first vehicle operating condition. A cap may be disposed on the pointer and opposite the substrate and over the post, with a first coil of electrically conductive material disposed therein. A light source may be mounted to the pointer and in electrical communication with the first coil. A second coil of electrically conductive material may provide power to the first coil via non-contact coupling. A stepper motor may cause the pointer to rotate. The second coil may be formed as a trace in a metal layer of a printed circuit board disposed beneath the substrate. The light source may cause the pointer to be illuminated. Alternatively, the light source may cause an applique in the cap to illuminate as a telltale icon, indicating a second vehicle operating condition.

Abstract: The process for the control and activation of vehicle dashboard indicators (121, 122, 221) consists in distributing the indicators into x groups (1, 2, 3, 4) of indicators (121, 122, 221) and in performing a time division multiplexing of the groups (1, 2, 3, 4), by determining an actual value of instantaneous excitation of the indicators (121, 122, 221) and by regulating a shape factor for multiplexed control and activation of the indicators (121, 122, 221) as a function of the deviation between the actual excitation value and a preset value.
