    • A wireless compass for vehicles includes a compass sensor installed in a first location of a vehicle. The compass sensor sends information regarding the heading of the vehicle via a wireless transmitter. A compass display includes a complementary wireless receiver which receives the data from the compass sensor. The compass display and receiver are located at a second location convenient for the driver. The display displays the heading of the vehicle based upon the data received from the compass sensor.

    • A processor uses signals from at least two GPS receivers and a 3-component accelerometer located on a stable non-magnetic platform to determine the roll, yaw and pitch angles of the platform, thus providing a measurement of geographic north. The processor also uses signals from a 3-component magnetometer on the platform to determine the magnetic north and thence the magnetic declination. A proton magnetometer is used to provide a check on the measurements of the 3-component magnetometer. Additionally, three single component magnetometers provide a measure of the local magnetic field gradient and serve to monitor artificially induced magnetic fields. An alternate embodiment of the invention uses at least three GPS receivers and may dispense with the 3-component of accelerometer to determine geographic north. Temporal local variations of the earth's magnetic field are tracked and used to correct conventional magnetic well surveys. For use in offshore drilling applications where the rig is on a drillship, the platform floats on water away from the drillship and tethered to a buoy. Signals from an inertial motion sensor are used by the processor to correct the observations of the GPS sensors, the magnetometers and the accelerometers for the motion of the platform in water.
    • 处理器使用来自位于稳定非磁性平台上的至少两个GPS接收器和3组件加速度计的信号来确定平台的滚动,偏航和俯仰角度,从而提供对北部地理位置的测量。 处理器还使用来自平台上的3分量磁力计的信号来确定磁北极,从而确定磁偏角。 质子磁强计用于提供对三组分磁强计测量的检查。 另外,三个单分量磁力计提供局部磁场梯度的测量,并用于监测人为感应的磁场。 本发明的替代实施例使用至少三个GPS接收器,并且可以免除加速度计的3分量以确定北部地理位置。 跟踪和使用地球磁场的时间局部变化来纠正传统的磁场测量。 对于钻机在钻井船上的海上钻井应用场合,该平台将浮在水面上,远离钻井船并拴在浮标上。 来自惯性运动传感器的信号由处理器用于校正GPS传感器,磁力计和加速度计对于平台在水中的运动的观察。

    • Concentrated lines of flux through two loosely mounted magnetically contacting reeds (12, 14) are intermittently mechanically interrupted by breaking the contact infinitesimally, thus deriving a near-maximum generated EMF in a coil (20) surrounding the contact. A piezo transducer (28) driven in feedback arrangement by an oscillator (30) provides an energy-efficient drive for a hammer (32) that irregularly strikes one of the reeds. A compass based on this irregular modulation of a flux path is shown and other devices based upon this principle are mentioned.
