  • Patent number: 11292518
    Abstract: An absolute steering angle sensor includes a single main gear having first gear teeth with a first pitch, second gear teeth with a second pitch, wherein the first and second gear pitches are different. A first magnet gear is driven by the first gear teeth, wherein the first magnet gear has a first gear profile and a first diameter. A second magnet gear is driven by the second gear teeth, wherein the second magnet gear has a second gear profile and a second diameter. The first and second gear profiles are different, and the first and second diameters are different. A first magnet rotates with the first magnet gear and emits a first magnetic field, and a second magnet rotates with the second magnet gear and emits a second magnetic field. A sensor assembly measures strengths of the first and second magnetic fields and calculates an absolute steering angle.

  • Patent number: 8065973
    Abstract: A panel for an indicating instrument has a base plate. The base plate has a line pattern with lines. The line pattern is defined by projections and grooves. A desired metal-like appearance is converted into a glossiness ratio Gp/Gv. The projections and grooves are formed at intervals and have at least one dimension in a direction perpendicular to the surface such that the surface has a predetermined glossiness ratio Gp/Gv. Gp is a glossiness measured in a direction parallel to an axis of at least one line. Gv is a glossiness measured in a direction perpendicular to an axis of at least one line.

  • Patent number: 7145309
    Abstract: Provided herewith is an improved scheme for parking a load such as an indicator pointer and calibrating its position in a system for controlling the position of the load. The system also has a stopper for physically impeding the load when it is to be parked. In one embodiment, a parking method involves driving the motor in a reduced torque mode to move the load toward the stopper, stopping the load at the stopper while the motor is driven in the reduced torque mode, and maintaining the motor in a reduced torque mode until transitioning to an insignificant torque mode.
