摘要： An antenna includes a central loop and four adjacent coplanar eccentric loops. The central loop creates a magnetic field that is essentially perpendicular to the antenna. The centres of gravity of the four eccentric loops are essentially located on the periphery of the central loop and the eccentric loops are supplied in such a way as to predominantly create a rotating field in a plane parallel to the plane of the antenna. The eccentric loops can be associated in pairs of non-adjacent loops in such a way as to generate electromagnetic fields of opposite phases in the respective pair. In this way, the two loops of a pair can be connected such that the same current flows through them in opposite trigonometric directions. A radiofrequency generator can supply first and second excitation signals alternately on two outputs, respectively to the central loop and to the eccentric loops.

摘要： The microsystems communicate by electromagnetic transmission, preferably by radio frequency, with a control circuit. An initialization phase of the method of addressing successively comprises addressing, by the control circuit, of each microsystem by an identification code that is proper to the latter and storing, in a register of the microsystem, of a reduced addressing code supplied by the control circuit. A subsequent addressing phase comprises transmission to all the microsystems, by the control circuit, of reset signals and increment signals. Each microsystem monitors resetting of at least one counter upon receipt of a reset signal and incrementation of the content of the counter upon receipt of an increment signal. Each microsystem compares the contents of its counter and of its register so as to trigger execution of a pre-determined command when these contents are identical.

摘要： This method of identification between an interrogation system (1) such as an arch and labels (E) placed on objects to be identified and called upon to pass through the interrogation field (2) functions by the sending of control signals from the interrogator (1) to the labels (E) so that the latter transmit their codes. The known interrogation mode in which the codes are supplied bit by bit and the labels responding simultaneously are inhibited in turn so that only one is active and identified at any one time, is preceded by an identification test during which all the labels send their code at one go all at the same time, which allows immediate identification if only one label is present. When a label has been identified, the interrogator (1) isolates it in order to exchange particular information with it.
