Abstract: The invention relates to a method for identifying electronic labels provided with an identification code consisting of a plurality of rows, by means of a base station emitting interrogation commands (104, 108, 124, 128, 140) specifying at least one row of said code, each label emitting, in response to the base station, the value of the code thereof for each said row (110, 126, 130, 142). The inventive method consists of the following steps: the electronic labels are interrogated (104, 108), in an interrogation step, for at least one row of the code, and, if at least one electronic label emits a response (110), a signalisation step is performed by the base station when it has received two responses, the labels that do not have a pre-determined value for the interrogation row are subjected to a temporary inhibition step (114, 134) when the base station signals that it has received two responses, and a storage step (114, 134) is performed for the storage of each row in the labels that are temporarily inhibited.

Abstract: A device used to protect the hoof of a horse, replaces a horseshoe and takes the form of a sole (1) which is glued to the lower surface of the hoof, i.e. the surface that rests on the ground. The sole (1) is made from a low-density synthetic material. Moreover, at least one part of the sole includes at least two stacked layers (2, 3) of material having different hardness values. One of the layers (2) has a greater hardness value in order to withstand wear and abrasion, the layer forming the surface of the sole (1) that rests on the ground, while another layer (3) has a lower hardness value in order to form a shock absorbing and/or damping layer, the layer being intended to come into contact with the hoof. The assembly follows the natural deformations in the horny wall of the hoof.

Abstract: A method is provided for communicating between an electronic tag and at least two base stations, the electronic tag including a memory for storing a code having a plurality of levels, an apparatus for reading out a series of code values, at least one antenna for communicating with a base station, and a controller for responding to a read query from a base station by causing the read-out apparatus to read out the code values at at least one level, causing an antenna to transmit back a response signal and altering the code in the memory in response to a write query from a base station. In a write step, the electronic tag passes close to the first base station, and a base station proximity value is written into a predetermined code level. A transmission step is carried out when the electronic tag passes close to the second base station.

Abstract: A method is provided for remotely identifying electronic or radio frequency tags, typically those used to mark articles, from a station, each of the tags having its own code constituted by digits, in which identification of a tag comprises the steps of issuing interrogation signals from the station for different digit positions and employing procedures to accelerate tag identification once a first tag has been found. A suitable station and tag are also provided.

Abstract: An electronic tag and a method for remote interrogation of electronic tags from a station are provided in which, in reply to polling signals sent from a station, tags send responses which may interfere, the method comprising a step in which the tags are brought into phase before sending their responses.

Abstract: A power and modulation circuit, notably for a passive remotely-pollable electronic tag is provided, the circuit having a coil for picking up an inductive field and modulating it, circuitry being provided whereby circuits of the tag can be continuously powered while the inductive field is being modulated.

Abstract: In particular for reducing the waiting time at the checkouts of self-service supermarkets, articles are registered by providing each article with a microcircuit (24) having a loop for picking up high frequency energy and for responding to an interrogation by transmitting a modulated message at high frequency representing an article-identifying signature. An article (20) is taken into account by exciting its microcircuit by applying an energy-supplying and interrogation high frequency signal thereto to cause it to transmit the modulated signal of the signature, the modulated signal is picked up by memory means causing the signatures to correspond to the prices of articles, the price of the interrogated article is stored in a memory, and it is displayed, and the price of the article is added to that of any articles that may previously have been taken into account.
