1. An electronic game board system comprising:
- a game board surface;
an excitation signal generator which generates an electromagnetic query signal;
a plurality of playing pieces positioned on the game board surface, each said piece including a transponder which receives the query signal and, in response thereto, generates an identifying answer signal; and
a plurality of sensors which, upon receipt of the answer signal, generate a plurality of sensor signals responsive to the location of at least one playing piece for automatically and non-discretely sensing location of the playing pieces.

30. A position determining system comprising:
-
a board surface; an excitation signal generator which generates an electromagnetic query signal; at least one movable object positioned on the board surface, each object including a transponder which receives the query signal and, in response thereto, generates an identifying answer signal; and a pair of sensor coils, each coil including a plurality of sub-coils not all having the same width, the sub coils of one sensor coil being substantially aligned with a first edge of the board and the sub-coils of the other sensor coil being substantially aligned with an edge of the board opposite the first edge, the pair of coils generating a pair of sensor signals in response to a received answer signal. - View Dependent Claims (31, 32, 33, 34, 35)

36. A system comprising:
-
a board surface; at least one moveable object positioned on the board surface, said object including a transponder which receives an electromagnetic query signal and, in response thereto, generates an identifying answer signal; and an excitation signal generator which generates an electromagnetic query signal including an excitation coil comprising a plurality of zoned sub-coils, each zoned sub-coil including at least one zone bounded by a clockwise current loop produced by the excitation coil and at least one zone bounded by a counterclockwise current loop produced by the excitation coil. - View Dependent Claims (37)
