Resonant coils for use with games and toys
First Claim
1. An electronic card game system for use with an initiator having a driving coil, comprising:
- a first card having a secondary coil with a capacitor;
a playing piece having a receiving coil, a power source, and one or more powered devices;
wherein the initiator and the first card may be placed on a playing surface so that a portion of the initiator and a portion of the first card are in direct contact with the playing surface and so that at least a portion of the driving coil and at least a portion of the secondary coil overlap;
wherein the first card and the playing piece may be placed on the playing surface so that at least a portion of the receiving coil and at least a second portion of the secondary coil overlap; and
wherein a driving signal initiated at the driving coil may be transmitted through the secondary coil and received by the receiving coil, and wherein the one or more powered devices of the playing piece consume more power than the driving signal received by the receiving coil can supply, but are powered by the power source of the playing piece when the driving signal is received by the receiving coil.

Abstract
An electronic card game system and method using NFC or RFID electromagnetic communication, including an initiator having a driving coil, a first card having a secondary coil with a capacitor, and a playing piece having a receiving coil. The initiator and the first card may be placed on a playing surface so that at least a portion of the driving coil and at least a portion of the secondary coil overlap. Similarly, the first card and the playing piece may be placed on a playing surface so that at least a portion of the receiving coil and at least a second portion of the secondary coil overlap. These overlapped coils allow a driving signal initiated at the driving coil to be transmitted through the secondary coil and received by the receiving coil.

9. A method for playing an electronic card game system, comprising the following steps:
-
providing a first card with a first resonant coil; placing the first card directly on a playing surface; providing an initiator with a driving coil, placing the initiator on the playing surface relative to the first card so that a portion of the initiator is in direct contact with the playing surface and so that at least a portion of the first resonant coil and the driving coil overlap; providing a playing piece with a receiving coil, a power source, and one or more powered devices; placing the playing piece on the playing surface relative to the first card so that at least a portion of the first resonant coil and the receiving coil overlap; initiating a driving signal at the driving coil and relaying the driving signal through the first resonant coil and to the receiving coil; and powering the one or more powered devices of the playing piece via the power source of the playing piece in response to receiving the driving signal at the receiving coil, wherein the one or more powered devices consume more power than the driving signal received by the receiving coil can supply. - View Dependent Claims (10, 11)

12. An electronic card game system for use with an initiator having a primary coil capable of generating a radio-frequency signal, comprising:
-
a playing card having a secondary coil for receiving and retransmitting the radio-frequency signal; and a playing piece having a receiving coil, a power source, and one or more powered devices, wherein the playing piece rests on top of the playing card while the primary coil is adjacent the playing card, and wherein the radio-frequency signal may be transmitted through the playing card from the initiator to the playing piece, and wherein the one or more powered devices of the playing piece consume more power than the radio-frequency signal received by the receiving coil can supply, but are powered by the power source of the playing piece when the radio-frequency signal is received by the receiving coil. - View Dependent Claims (13, 14, 15, 16)
