ANALOG GAUGE WITH WIRELESS ILLUMINATION

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...

Beschreibung
Zusammenfassung:	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.
