1. A set comprising:
- an RF transponder to use with a toy;
at least two antennas to emit detection signals to the RF transponder; and
a multiplexer coupled to the two antennas to activate a first one of the antennas at a different time interval than a second one of the antennas.

Abstract
A system of antennas, software, and methods are provided for locating and identifying objects that include RF transponders. A single antenna driver feeds a signal to a multiplexer, which activates sequentially the antennas of the system. A return signal is matched with the known signatures of an object. The object is matched with the known location of the antenna that provided the return signal.

13. A set for use with a program comprising:
-
a play device;
at least two antennas to emit respective first and second detection signals at different time intervals, the antennas positioned at first and a second antenna locations of the play device respectively;
a first toy to place on the play device including a first RF transponder to generate a first return signal in response to the first detection signal; and
a second toy to place on the play device including a second RF transponder to generate a second return signal in response to the second detection signal;
wherein the program is adapted to identify the first return signal with the first toy and the second return signal with the second toy.

18. An article comprising:
- a storage medium, said storage medium having stored thereon instructions, that, when executed by at least one device, result in;
emitting a first detection signal from a first antenna;
emitting a second detection signal from a second antenna at a different time interval than emitting the first detection signal;
receiving a return signal from an RF transponder in response to one of the first and second detection signals; and
determining which one of the first and second antennas received the return signal.
- a storage medium, said storage medium having stored thereon instructions, that, when executed by at least one device, result in;

22. A method comprising:
-
emitting a first detection signal from a first antenna;
emitting a second detection signal from a second antenna at a different time interval than emitting the first detection signal; and
receiving a return signal from an RF transponder in response to one of the first and second detection signals. - View Dependent Claims (23, 24, 25, 26)
