Patent number: 9303991Abstract: An electronic device may have electrical components mounted in alignment with an electronic device housing. A compass in the electronic device housing may potentially be misaligned with respect to the electrical components and the electronic device housing. Reference devices having compasses may be used to gather compass data while one or more electrical components in the reference devices are controlled to generate magnetic fields that are detected by the compasses. An electronic device may be calibrated in a factory or in the field using calibration data produced by comparing compass readings gathered from the compass in the device while controlling electrical components in the device to compass data from the reference devices. Calibration data may be applied to compass readings in real time to correct for misalignment between the compass and the electronic device housing.Type: GrantFiled: July 2, 2014Date of Patent: April 5, 2016Assignee: Apple Inc.Inventor: Ryan J.

Patent number: 5995913Abstract: Disclosed is a method of stabilizing the horizon of magnetic compasses. At measuring points measurements are taken of spatial components of the geomagnetic field vector and of an overall acceleration vector that is equal to the difference of the acceleration vector due to gravity and the acceleration vector of the magnetic compass. Taking into account the time rates of change of the measured components, the positional relation of the current horizon of the magnetic compass is determined relative to the stable horizon. Using quality functions that signal the deviation of the new spatial position relative to the one previously defined, an estimation method is used to evaluate the accuracy of the stabilized horizon of the system. A horizon can be produced that is largely unsusceptible to movement-induced accelerations of the device equipped with a magnetic compass.Type: GrantFiled: December 18, 1997Date of Patent: November 30, 1999Assignee: Leica Geosystems AGInventors: Frank Dittrich, Peter Nachbaur, Silvio Gnepf

Patent number: 5701259Abstract: A method is specified for stabilizing the directional display of magnetic compasses on bodies moving in a magnetic field, in particular the terrestrial magnetic field, against magnetic interference sources. The spatial components of the magnetic field vector are measured at a measuring point within a first interference-free measurement region.

For a further measuring point, the quality function and the measured component values are used to estimate the magnetic field vector at this measuring point and to measure the spatial components of this magnetic field vector.Type: GrantFiled: November 6, 1995Date of Patent: December 23, 1997Assignee: Leica AGInventor: Frank Dittrich

Patent number: 5566462Abstract: A magnetic compass comprising an arrangement to displace a correcting marker to create a compass correcting coefficient equal to the sum of the variation and the deviation errors effecting the compass so as to counteract the compass error, and to indicate the true course. The correcting marker becomes the steering reference and a vessel is steered so that the correcting marker is aligned with the true course to be steered by the vessel. Repeaters fed from this compass, which repeaters are fed by the hunting between the compass card and the displaceable correcting marker, indicate the true course as well as true bearings. The displacement of the correcting marker can be controlled from a computer programme which displaces the correcting marker in dependence upon the effecting variation and deviation. Thus the magnetic compass shows true course and the repeaters show true course and true bearings automatically.Type: GrantFiled: January 26, 1995Date of Patent: October 22, 1996Inventor: Fredun Ruston
