摘要： La presente invencion proporciona un método y un aparato el cual perfecciona la probabilidad de identificacion de un numero de transmisores (1), típicamente transpondedores, los cuales están todos transmitiendo datos a un receptor. La invencion es aplicable a un numero de sistemas que incluyen los sistemas de transpondedores de radio frecuencia pasivos, sistemas en los cuales un numero de transmisores autoalimentados debe ser identificado por un receptor, o sistemas en los cuales un numero de transmisores radiodifunden usando un algoritmo de "regrese e intente de nuevo" retardo aleatoriamente. Cada transmisor (1), está adaptado para transmitir a intervalos y comprende un medio para generar las transmisiones, un medio para calcular la duracion de los intervalos entre las transmisiones sucesivas y un medio (20) para habilitar al transmisor a intervalos aleatorios o pseudoaleatorios relacionados a una frecuencia operativa de medios de regulacion de tiempo, locales (21). En los sistemas de RFID pasivos, la frecuencia de los medios de regulacion de tiempo, locales es indeterminada, estando sin especificar hasta que el transmisor esté en operacion.

摘要： Un aparato y método adecuados para su uso como un dispositivo electronico de localizacion remota. El método incluye sincronizar un receptor, no programado, con un transmisor, de modo que este receptor, no programado, responda solamente al transmisor. Este transmisor incrementa continuamente un elemento de almacenamiento, cuando se aplica inicialmente energía al transmisor, y detiene el incremento del elemento de almacenamiento cuando se detecta un primer evento. En seguida, el transmisor guarda el valor del elemento de almacenamiento en la memoria, como la unica clave de identificacion. El transmisor luego transmite la clave de identificacion por un primer período de tiempo predeterminado, a una frecuencia seleccionada previamente. El receptor inspecciona la frecuencia seleccionada previamente buscando una clave de identificacion recibida por un período de tiempo predeterminado, después de aplicar la energía eléctrica al receptor. Este receptor luego verifica la validez de la clave de identificacion recibida y determina si existe una clave de identificacion anterior en la memoria del receptor. Este receptor guarda la clave de identificacion recibida en la memoria, si no se ha encontrado una clave de identificacion anterior en la memoria y detiene la inspeccion. El receptor luego inspecciona periodicamente el intervalo de frecuencia seleccionado previamente y compara la clave de identificacion recibida con la clave de identificacion anterior. El receptor emite una indicacion al usuario si la clave de identificacion recibida es igual a la clave de identificacion anterior.

摘要： A data card, such as a cash card, bears a magnetic strip on which data may be magnetically stored and an optical panel comprising a series of parallel black stripes. Apparatus for use with the card has an optical infra-red reader (2), a magnetic read/write device (3) and signal processing circuitry (6). Reader (2) permits the velocity of travel of the card relative to the apparatus on insertion by the user to be sensed, which in turn enables magnetically encoded information to be read from the magnetic strip and processed without corruption. The apparatus and card can therefore function without the necessity for a complex and expensive card transport.

摘要： A reader identifies information, such as the identity of an object at a transponder, provided in binary form by the transponder. The reader initially generates a pulse which activates the transponder into transmitting a series of signals, such as by magnetic induction, to the reader. Upon each count of a particular number of signals in the reader, the reader generates an additional pulse which causes the transponder to transmit a new series of signals to the reader. The generation of the pulses by the reader may occur through the charge and discharge of energy in a storage member such as a capacitance. The series of signals produced by the transponder may have either a first frequency or a second frequency. The signals may be generated in each sequence at the first and second frequencies in an order dependent upon (a) the binary code identifying the object at the transponder and (b) the polarity of the pulse produced by the transponder in such sequence. The signals may be generated at the second frequency by connecting a capacitance across a coupling coil at the transponder. The reader then identifies the information by demodulating the signals received by it at the first and second frequencies. The reader is able to interrupt at any time the generation of the sequences of signals at the transponder when it does not receive the signals transmitted by the transponder. The reader then operates on a free running basis to generate pulses of opposite polarity at a relatively low frequency. In this way, the reader is constantly prepared to activate the transponder when the transponder becomes subsequently disposed within the effective range of the reader.

摘要： A write and read system is disclosed which uses, to defeat counterfeiting of value-rated magnetic cards, a synchronous recording of a signal on two parallel tracks (a-a') separated by a third track (b) on which a coded synchronization mark is simultaneously recorded, and simultaneous half-width reading of the two side tracks (a-a') and full-width reading of the center track (b) in order to derive a marked read signal whose shape, strictly dependent on the write procedure, constitutes the card recognition and validation code.

摘要： scannable data transfer device for presenting data in a form to be scanned by a magnetic hand scanning device comprises a fixed magnetic flux pattern scannable data transfer strip portion (15) and a longitudinally aligned scannable data transfer strip portion (14) including along its length a plurality of transversely oriented electrical conductors (20). A source (22) of data to be scanned supplies signals through a gate (23) to a register (24) which has a stage (25) for each conductor. Each stage is connected to its conductor by a driver circuit in a stack (27), so that current is supplied to the conductor in a direction dependent upon the state of the stage (25). The resultant current flows in the conductors provide a selected and variable flux pattern indicative of the data to be transferred, which may be scanned by the same device in the same scanning movement as the fixed pattern strip portion (15).

摘要： A verifying device for a key card on which a magnetic signal is recorded is formed of a set card on which a predetermined reference magnetic signal is recorded, a magnetic sensor consisting of a saturable core and a winding wound thereon, an oscillator for supplying a voltage to said winding, a switching element connected to the winding, a power source connected between both ends of the switching element, and an output terminal led out from one of both ends of said switching element. In this case, the saturation magnetic field of the saturable core is so selected that it is larger than the magnetic field itself generated from the reference magnetic signal recorded on the set card in absolute value but smaller than the sum magnetic field of those from the set and key cards in absolute value when the key card is a correct card, so that when the correct key card is inserted into the device to be verified with the set card, the sum magnetic field becomes larger than the saturation magnetic field of the saturable core in absolute value, hence the saturable core is saturated, no output appears at the winding, thus said switching element is turned off and an output indicating that the key card is coincident with the set card is produced at the output terminal.

摘要： A magnetoresistive (MR) card-reading head (2) comprises a sapphire substrate (6) with MR strips (8A, 8B) vapour-deposited on one face (F2). The substrate is mounted in a holder (4) so that the opposite face (F1) thereof is urged into face-to-face contact with magnetically-encoded cards which are passed through a guideway (1), the information on the cards thus being read through the thickness of the substrate (6). This construction is particularly useful in the provision of MR strips (8A, 88) of crooked configuration, such as are required in high-security readers for access-control equipment.
