Patent ID: 6882339

Claim:
An electromagnetic induction system having single-induction-loops and multi-induction-loop, comprising: a single-induction-loop, deployed along left and right side of X axis and upper and lower side of Y axis, one end of said single-induction-loop being electrically connected with a first switch assembly and the other end of said single-induction-loop being electrically connected with a common contact to form independent -type section; a multi-induction-loop, which further comprising: a plurality of first induction loops, deployed along the direction of X axis, one end of said a plurality of first induction loops being electrically connected with a second switch assembly and the other end of said a plurality of first induction loops being electrically connected with a common contact, and each of said first induction loops having a plurality of close-like areas; a plurality of second induction loops, deployed along the direction of Y axis, one end of said a plurality of second induction loops being electrically connected with a third switch assembly and the other end of said a plurality of second induction loops being electrically connected with a common contact, and each of said second induction loops having a plurality of close-like areas; a common contact, being electrically connected with said single-induction-loop and said plurality of first induction loops and said plurality of second induction loops respectively; a first switch assembly, being electrically connected with a plurality of single-induction-loops; a second switch assembly, being electrically connected with said plurality of first induction loops; a third switch assembly, being electrically connected with said plurality of second induction loops.
