Abstract: A Radio Frequency Identification (RFID) structure. The RFID structures includes a tag stack of N essentially identical RFID tags and an object stack of N essentially identical objects. N is at least 2. Each tag is attached to a corresponding object and includes an electronic chip, an antenna, and at least one pair of electrical contacts. The N tags are daisy chained together in electrical contact via the at least one pair of electrical contacts in the tags. The tag stack is configured to receive power from an external power source located outside of the RFID structure. A method for localizing an object in the object stack includes receiving an external signal in each tag via the antenna, and enabling or not enabling a lighting of a lighting device in each tag in dependence upon data in the external signal.

Abstract: A method and system for localizing an object among a set of objects, each equipped with an improved RFID tag. The tag includes an RFID chip, an antenna, a visual indicator, an AC/DC converter, and at least a pair of conductive surfaces adapted for receiving power from an external source and for powering the electronic chip according to capacitive coupling. Each conductive surface of the pair is designed to form the half of a capacitor, the capacitor being formed when the electronic tag and a similar electronic tag are attached to a neighboring adjacent object. To localize an object, an RFID reader is used, fed with the identifier of the object to be localized. All the capacitively coupled RFID, in the RFID reader range, receive a reading trigger that carries the identifier.

Abstract: A method and systems for collecting data from a huge number of pre-filled forms are disclosed. According to the method and systems of the invention, the pre-filled forms comprise RFID tags, check boxes, and electrical connection between the RFID tags and the check boxes so that responses are modified according to checked boxes. In a preferred embodiment, each check box comprises at least two electrical terminals electrically connected to the RFID tag through a register. Using a pencil with conductive ink for checking the check boxes establishes an electrical contact between the terminals that modify the value of the register that in turn, modifies the response of the RFID tag. When the check boxes identifiers of a form have been collected, the identifier of the form is stored within the RFID reader to avoid further reading of the RFID tag, or the identifier of the RFID tag is erased.

Abstract: A method and system for locating tires is disclosed. According to the invention, an RFID reader antenna is positioned at a predetermined location such that the distances between the reader antenna and the tires are different. Each tire embeds at least one RFID tag. The distance between the reader antenna and each RFID tag is determined by measuring the delay required for the signal to be reflected by the RFID tag. Since all the distances between the reader antenna and the RFID tags are predetermined, knowing the distance between the reader antenna and a particular RFID tag allows the determination of the position of the particular RFID tag and of the tire.

Abstract: A connector for twisted pair cables used to transmit high frequency data signals. The conductors of the twisted pair are connected to contact blades by an auto-latching mechanism adapted to ensure contact with the corresponding contact blades of a mating connector. Each contact blade has constant thickness but has an initial width in its rectilinear part and a narrower second width in the portion where contact is made with the corresponding portion of the contact blade of the other connector, such that the common mode impedance is the same in the rectilinear part and in the portion where the contact takes place.

Abstract: A strain relief device for an electrical connector designed to be interconnected to another connector of the same type to connect cables containing at least one twisted pair for the transmission of very high-frequency differential data signals. Conductors are connected in a connection block by insulation displacement contacts to contact blades, adapted to ensure contact in an interface block with the corresponding contact blades of the other connector. The device has two guillotines sliding in side grooves of the connection block. The side edges of the guillotines form a 90° angle between them and a 45° angle in relation to the direction of movement during the clamping operation, such that the side edges of the guillotines form a diaphragm when they approach one another, thereby ensuring a 360° seal preventing the cable from being deformed or damaged.

Abstract: A connector for cables containing at least one twisted pair for transmission of very high frequency signals. The conductors of the pair are connected in a connection block by insulation displacement contacts to contact blades, adapted to ensure contact in an interface block with the corresponding contact blades of the other connector. When connection is made, the geometry of the elements of the connection block is the same as the geometry of the elements of the interface block. This geometry is adapted so that the differential mode impedance between the conductors of each pair and the common mode impedance between the conductors and the shielding of the pair are respectively equal to the differential mode impedance between the contact blades and the common mode impedance between the contact blades and the shielding of the connector.

Abstract: An improved electrical connector of the RJ45 ANSI-568 type for terminating a multi-wire cable. The connector has two internal management bars for guiding the cable's wires sequentially through the connector from entry to termination. A first wire of a first wire pair and a second wire of a second wire pair that are adjacent as positioned by the first management bar are not adjacent as positioned by the second management bar. Opposing near-end crosstalk components are introduced into each pair of the cable's wires, thereby reducing near-end crosstalk. In one embodiment, the first management bar positions a set of four wire pairs according to a pattern W1′, W1, W2, W3, W3′, W2′, W4′, W4, and the second management bar positions the same set of four wire pairs according to a pattern W1, W1′, W2, W3′, W3, W2′, W4, W4′.
