Electromagnetic inductive system with multi-induction loop layout and battery less pointer device and its method for locating the coordinate |
摘要 |
A multi-induction loop layout of an electromagnetic inductive system is disclosed. The multi-induction loop layout of the invention comprises a plurality of inductive loops, one terminal of each inductive loop connecting to a loop switch, and the other terminal connecting to the common node. Every logical inductive loop is a relative close inductive loop, the relative close inductive loop possessing a plurality of <custom-character file="US20040055793A1-20040325-P00900.TIF" wi="20" he="20" id="custom-character-00001"/>-type sections, forming a sawtooth-shaped region and corresponding to and closing each other to form a plurality of close-like regions. The form of which gradually approaches the multi-induction loop layout.
