  • Method and an apparatus for electronically identifying articles moving along a surface
    Patent number: 5021767
    Abstract: A method and an apparatus for identifying articles moving along a surface, especially suitable for conditions in which the surface and/or the articles comprise comparatively much electrically conductive material. The articles are provided with electronic responders, each having two electrodes which are insulated from each other and in operation, face the surface. The surface is provided with corresponding electrodes connected to a transmitter/receiver device. When the electrodes of a responder are located opposite the electrodes of the transmitter/receiver device, an electric field is produced between these electrodes, enabling information transfer between the responder and the transmitter/receiver device.
