DEVICE AND METHOD FOR ATTITUDE DETECTION, ATTITUDE SENSOR, AND ATTITUDE INDICATING DEVICE

摘要

PROBLEM TO BE SOLVED: To detect the attitude of the attitude indicating device in a three- dimensional space in the term of absolute values. SOLUTION: The attitude indicating device 101 having attitude indicating coils, which constitute resonance circuits of different resonance frequencies and which also have their coil surfaces directed differently, is arranged in the center position O of an attitude sensor 102 having attitude detecting coils L and M, and L' and M' which are arranged radially and coupled electromagnetically with the attitude indicating coils. Signals are sent and received between the attitude indicating coils and attitude detecting coils L and M, and L' and M' to detect the attitude of the attitude indicating device 101 in a three- dimensional space in the term of absolute values.
