Title (EN) IMPROVEMENTS IN AND RELATING TO ELECTRONIC GAME APPARATUS
(FR) AMELIORATIONS APPORTEES A UN APPAREIL DE JEU ELECTRONIQUE
Abstract:
(EN) Electronic game apparatus for determining the presence and optionally the identity of playing pieces. Each playing piece (10) is provided with a resonator circuit, which may be tuned so that each playing piece or type of piece has a unique resonant frequency. The board is provided with transmit and receive coils (4, 6), to stimulate the resonator circuit of a piece and to sense the resonant signal respectively. An amplifier is provided between the two sets of coils to amplify the signal around the loop. A resonant signal results if a playing piece is placed on the square being tested. The frequency of this signal is detected and may then be determined and the piece identified.
(FR) Appareil de jeu électronique pour déterminer la présence et, éventuellement, l'identité de pièces. Chaque pièce (10) est équipée d'un circuit résonateur qui peut être accordé de manière à ce que chaque pièce ou type de pièce possède une fréquence de résonance unique. Le tableau est muni de bobines de transmission et de réception (4, 6) qui stimulent le circuit résonateur de telle ou telle pièce et en captent le signal de résonance, respectivement. Un amplificateur est installé entre les deux jeux de bobines pour amplifier le signal à proximité de la boucle. Un signal de résonance se déclenche lorsqu'une pièce est placée sur la case ainsi contrôlée. La fréquence de ce signal est alors détectée, puis déterminée afin de permettre l'identification de la pièce.
