Abstract: A compass system configured to compensate for electromagnetic interference in a vehicle is provided that includes an electronic device that is sensitive to electromagnetic interference (EMI), wherein the electronic device is positioned in a vehicle such that the electronic device receives EMI from another accessory in the vehicle, and wherein the electronic device is configured to compensate for the EMI, such that the EMI field caused by the accessory can be detected and added to existing calibration point while the accessory is powered on.

Abstract: A vehicular rearview assembly that has a rounded outer perimeter edge to satisfy safety standards and contains an EC element having a complex peripheral ring, a front surface that is fully observable from the front of the assembly, and a user interface with switches and sensors that activate and configure, in cooperation with electronic circuitry of the assembly, pre-defined function(s) or device(s) of the assembly in response to the user input applied to the user interface. A complex peripheral ring may include multiple bands the structures of which is adapted to provide for specified optical characteristics of light, reflected off of the ring. Electrical communications between the electronic circuitry, the mirror element, and the user interface utilize connectors configured to exert a low contact force, onto the mirror element, limited in part by the strength of adhesive affixing the EC element to an element of the housing of the assembly.

Abstract: An electronic compass system includes a magnetic sensor circuit having at least two sensing elements for sensing perpendicular components of the Earth's magnetic field vector. A processing circuit is coupled to the sensor circuit to filter, process, and compute a heading. The processing circuit may determine whether too much noise is present in the output signals received from said magnetic sensor circuit as a function of the relative strength of the Earth's magnetic field vector. The magnetic sensor circuit may include three magnetic field sensing elements contained in a common integrated package having a plurality of leads extending therefrom for mounting to a circuit board. The sensing elements need not be perpendicular to each other or parallel or perpendicular with the circuit board. The electronic compass system is particularly well suited for implementation in a vehicle rearview mirror assembly.

The control circuit determines whether daytime or nighttime conditions are present as a function of the ambient light level sensed by the ambient sensor. During daytime conditions, the control circuit responds to light levels sensed by the glare sensor to control a contrast ratio of light originating from the display and light reflecting from the partially transmissive, partially reflective area of the reflector.

Abstract: An electronic compass system includes a magnetic sensor circuit having at least two sensing elements for sensing perpendicular components of the Earth's magnetic field vector. A processing circuit is coupled to the sensor circuit to filter, process, and compute a heading. The processing circuit further selects an approximating geometric pattern, such as a sphere, ellipsoid, ellipse, or circle, determines an error metric of the data points relative to the approximating pattern, adjusts the pattern to minimize the error, thereby obtaining a best fit pattern. The best fit pattern is then used to calculate the heading for each successive sensor reading provided that the noise level is not noisy and until a new best fit pattern is identified. The electronic compass system is particularly well suited for implementation in a vehicle rearview mirror assembly.
