Coil arrangement for e.g. aligning hall sensor in measuring space to detect tongue movement of test person during speaking, has satellite coils whose direction vectors run at pitch angle, where angle data allows preset angle error in plane

摘要

The arrangement (1) has three central coils (2-4) with radius vectors and direction vectors arranged orthogonal to each other. Six satellite coils (5-10) attach two of the central coils. Directions of the satellite coils run orthogonal to each other, and direction vectors of the satellite coils run at a pitch angle of 135 to 15 degree Celsius to a direction of the satellite coils from the direction vectors of the associated central coils in a plane, where angle data allows an angle error of maximum of plus or minus 30 degree Celsius in the plane in the orthogonal and opposite directions.
