摘要:
The present invention relates to an inventory system for objects contained in a space delimited by an enclosure (10), said system comprising a tag (20T) fixed to each of the objects to be inventoried (20) and a reading point (30) provided with at least one antenna (31, 32, 33) for emitting an electromagnetic wakeup wave confined to the interior of said enclosure (10) so that a tag (20T), on receipt thereof, becomes active and then emits its identification data destined for said reading point (30). It is characterized in that it comprises means (41, 42) for controlling the emission power of said electromagnetic wakeup wave in accordance with a power variation model defined by a series of emissions by said or each antenna (31, 32, 33) according to scales at different power levels from one scale to another so as to carry out said inventory. The present invention also relates to an inventory method implemented by such an inventory system.

According to one embodiment, an IC card includes a communication unit, a magnetic field strength determination unit, and a magnetic field strength transmission processing unit. The communication unit transmits/receives data to/from an external apparatus in a non-contact manner. The magnetic field strength determination unit determines a magnetic field strength necessary to execute processing. The magnetic field strength transmission processing unit causes the communication unit to transmit, to the external apparatus, information indicating the magnetic field strength determined by the magnetic field strength determination unit.

Exemplary embodiments are directed to wireless power. A chargeable device (700) may comprise receive circuitry (704) for coupling to a receive antenna (702). The receive circuitry may comprise at least one sensor (716) to sense one or more parameters associated with the chargeable device. Further, the receive circuitry may comprise a tuning controller (718) operably coupled to the at least one sensor to generate one or more tuning values in response to the one or more sensed parameters. Additionally, the receive circuitry may comprise a matching circuit (708) operably coupled to the tuning controller for tuning the receive antenna according to the one or more tuning values.
摘要:
A system is provided for identifying implanted medical devices, leads and systems, as well as objects in close proximity to a patient having an implanted active medical device, using a radio frequency identification (RFID) tag having retrievable information relating to the AIMD, lead system and/or patient. An RFID tag communicator includes a circuit for limiting the total continuous transmit time of an interrogation signal, and a time-out circuit for delaying a second and any subsequent interrogation of the RFID tag.

In a monitoring device consisting of a reader and a data carrier, the reader (100) comprises a control unit (101), a memory (102), a digital signal generator (103), an output driver (104), resonance capacitors (105, 107) and a transmitter coil (106). The digital signal generator (103) is adapted for supplying a digital bit sequence selected among, at least two, bit sequences stored in the memory (102) whereby the strength of the magnetic field generated by the transmitter coil (106) can be varied dependent on the bit sequence selected by the control unit (101). The invention further provides a method of controlling the strength of a magnetic field generated by the reader of the monitoring device.

摘要:
Die Erfindung betrifft ein System zur Lagerung und Überwachung von Gütern, umfassend wenigstens eine Lagerebene, auf der die Güter an definierten Positionen platzierbar sind, so dass jedes Gut einer definierten Position zugeordnet ist. Jedes Gut ist dabei jeweils mit wenigstens einem passiven RFID-Transponder versehen, und das System umfasst mehrere Lesegeräte zur Erfassung dieser RFID-Transponder an den Gütern. Die Lesegeräte stehen in Verbindung mit einer Datenverarbeitungseinheit, welche Mittel zur Auswertung erfasster RFID-Signale der RFID-Transponder aufweist, und jeder Lagerebene des Systems sind wenigstens zwei Lesegeräte zugeordnet, die Transponder auf der betreffenden Lagerebene erfassen können. Das System zeichnet sich dadurch aus, dass die definierten Positionen für Güter nebeneinander in einer Reihe auf einer Lagerebene angeordnet sind und wenigstens ein Lesegerät entlang dieser Reihe von definierten Positionen verschiebbar und/oder in Bezug zu dieser schwenkbar ausgeführt ist. Ferner beinhalten die Güter wenigstens ein Material, das gegenüber elektromagnetischen Feldern eine Abschirmwirkung aufweist und an wenigstens einer definierten Position auf einer Lagerebene ist ein Lokalisationstransponder so angeordnet, dass der Lokalisationstransponder bei Positionierung eines Gutes im Bereich dieses Lokalisationstransponders aufgrund der Abschirmwirkung des betreffenden Gutes durch kein Lesegerät erfassbar ist.
摘要:
An IC card reading apparatus supporting different communication standards and providing users with excellent usability. Based on an instruction from a CPU, a linear power amplifier supplies, in a case of transmitting a radio signal of Type A, an antenna circuit with a power supply voltage of Type A supplied from a power supply switch circuit, and supplies, in a case of transmitting a radio signal of Type B, the antenna circuit with a power supply voltage of Type B supplied from the power supply switch circuit. In this way, both an IC card of Type A and an IC card of Type B can be read.
