Abstract:
A method for pairing a first element and a second element, wherein the first element and the second element form a first decoding system among a plurality of receiving decoding systems in a broadcasting network. Each receiving decoding system is adapted to descramble scrambled audiovisual information received over the broadcasting network. A first key unique in the broadcasting network is selected. A second key is determined according to the first key, such that a combination of the first key and the second key enables to decrypt broadcasted encrypted control data that is received to be decrypted by each receiving decoding system, the encrypted control data being identical for each receiving decoding system. The first key and the second key are assigned respectively to the first element and the second element.
Abstract:
An electronic card is disclosed including circuits of the protected zone include at least one control circuit. The electronic card further includes another zone defining a non-protected environment; the circuits of this zone do not need to comply with the distance constraint. The communication between the circuits of the protected zone and the non-protected environment is carried out by a communication circuit allowing or not allowing the electrical signals to pass. The passage of the electrical signals in the communication circuit is conditioned by an electrical control signal sent by the control circuit. Also disclosed is a method allowing the control circuit to be blocked if the electrical status of the signal controlling the passage of the signals does not correspond to the status imposed by the control circuit.
Abstract:
A process for homogeneously dispersing at least one reactant in a fluid matrix, characterized in that capsules of a first type containing the reactant(s) are prepared with a first encapsulation product and capsules of a second type containing the fluid matrix are prepared with a second encapsulation product which is compatible with the first, these two types of capsules bearing electric charges of opposite polarity, the capsules of the two types are combined by electric attraction and the first and second encapsulation products are removed so as to obtain a composite material consisting of the fluid matrix containing the reactant(s) in homogeneous dispersion form, and products obtained according to this process.

Abstract:
A flat discharge lamp transmitting radiation in ultraviolet or visible, including first and second flat, or substantially flat, glass elements substantially parallel to each other and defining an internal space filled with gas, the first and/or second glass element being made of a material that transmits the radiation; at least one first electrode and at least one second electrode, which may be at different potentials and may be supplied by an AC voltage, the first and second electrodes being associated with one or more main faces of the first glass element, the first and second electrodes being essentially elongate and substantially parallel to one another, and separated by at least one interelectrode space of given width substantially constant; and at least one third electrode which may be at a given potential associated with a main face of the second glass element and at least partly occupying, in projection, the interelectrode space.
Abstract:
The present invention relates to a flat discharge lamp (1000) that transmits in the visible and/or UV comprising first and second dielectric walls (2, 3) that are facing each other, kept parallel and sealed at the periphery (8), that thus define an internal space (10) filled with a plasma gas and comprising a source of UV and/or visible light (6); and first and second electrodes (4, 5) in separate planes parallel to the first and second walls, the first electrode (4) being at a potential V0 higher than the potential V1 of the second electrode, and the first electrode being arranged in the internal space and closer to the first dielectric wall than the second electrode. And the first electrode is spaced apart from the first dielectric wall by the gas, the first and second electrodes are separated by a flat electrical insulator (7) with at least one main face (71, 72), known as a perforated face, equipped with through-holes (73), at least one of the first and second electrodes is in contact with the main perforated face and has discontinuities at least in the extension of said holes.
Abstract:
To prevent being able to capture sensitive signals between electronic circuits placed on an electronic card, these circuits are arranged in a protected zone in such a manner so as not be distant from each other by more than a determined distance. The circuits of the protected zone comprise at least one control circuit. The electronic card further comprises another zone defining a non-protected environment; the circuits of this zone do not need to comply with the distance constraint. The communication between the circuits of the protected zone and the non-protected environment is carried out by means of a communication circuit allowing or not allowing the electrical signals to pass. The passage of the electrical signals in the communication circuit is conditioned by an electrical control signal sent by the control circuit. The invention also relates to a method allowing the control circuit to be blocked if the electrical status of the signal controlling the passage of the signals does not correspond to the status imposed by the control circuit.
