摘要： An interior rearview mirror system for a vehicle includes an interior rearview mirror assembly, a mirror casing, a reflective element, an information display, a compass sensor and control circuitry. The compass sensor is disposed in the mirror casing and has at least a first magnetoresponsive sensing element and a second magnetoresponsive sensing element. The information display is disposed behind the reflective element whereby information displayed by the information display is viewable through the transflective reflector by a driver of a vehicle when the information display is displaying information. The control circuitry determines a directional heading of the vehicle responsive to the sensing by the first and second magnetoresponsive sensing elements, and the control circuitry automatically compensates for a deviating magnetic field of the vehicle and generates a signal indicative of the directional heading of the vehicle. The information display displays the directional heading of the vehicle.

摘要： A heading sensor includes a housing containing an interferometer having a mirror movable in response to fluctuations in a gravitational force applied to the housing. The interferometer, responsive to a light beam, generates an optical signal modulated according to the relative displacement of the mirror. The housing further includes an electromagnetic coil positioned along an axis of the housing for generating a current signal indicative of fluctuations in a magnetic field applied to the housing. The heading sensor also includes a processor for determining a local gravitational field component according to the optical signal and a local magnetic field component according to the current signal.

摘要： One or more sensors in a portable electronic device have individual status parameter in response to different using configurations. When the portable electronic device operates in a first using configuration, an electronic compass in the portable electronic device loads a corresponding first default setting, according to the status parameter of the sensors operated in the first using configuration, and detects the geomagnetic field for outputting azimuth data. When the portable electronic device changes its configuration from the first using configuration to a second using configuration, the electronic compass stops detecting the geomagnetic field and loads a corresponding second default setting, according to the status parameter of the sensors operated in the second using configuration, and detects the geomagnetic field for outputting azimuth data. The electronic compass is capable of properly detecting the geomagnetic field by loading different default settings when facing interference of different magnetic fields.

摘要： Disclosed is a small-sized two-axis magnetic field sensor having a function to cause a magnetic field canceling an external offset magnetic field. The two-axis magnetic field sensor contains a plane coil disposed on a plane and four sets of magneto-resistance element pairs on a plane parallel to the plane coil. The plane coil includes at least two pairs of parallel conductors, and two magneto-resistance elements cross only a single conductor of the coil. A current for canceling the external offset magnetic field is determined in advance, and while a DC current that causes total magnetic fields of biasing magnetic fields plus a magnetic field for canceling the external offset magnetic field flows through the coil, intermediate potential outputs from the magneto-resistance element pairs are detected to measure a magnetic field direction, such as geo-magnetism.

摘要： A magnetic compass apparatus and method to account for magnetic distortion while determining a magnetic heading is disclosed. The method enables a compass module, comprising at least two magnetometers, to characterize its magnetic environment dynamically, while collecting data of a geomagnetic field; a user moves an apparatus through various orientations; the environment may or may not contain magnetic distortion influences. Data gathered by magnetometers and, optionally, accelerometers are processed through at least two filters before being transferred as a processed data set for repetitive measurement calculations. A series of calculations is executed recursively in time by solving one or more linear vector equations using processed data.

摘要： For an observer equipped with a first azimuth data source responsive to a magnetic field to deliver first azimuth data, such as a compass, and with a second azimuth data source delivering second azimuth data and which is independent of magnetic fields, such as a gyroscope. The azimuth is determined by: analyzing the first and second azimuth data to determine whether a magnetic disturbance is present, and determining azimuth selectively on the basis of: the first azimuth data, the second azimuth data, or a combination of the first and second azimuth data, as a function of the result of the comparing step. In an embodiment, the choices of azimuth data source and events such as magnetic disturbances, sensor updates, types of trajectory deduced, are stored as a history sequence over successive time windows, by analogy with a DNA sequence, and is exploited for optimizing azimuth or navigation results.
