摘要： A system and method for communicating between an interrogation device (2) and at least one electronic label device (1). The system includes an interrogation device (2) for generating an interrogation field using an interrogation signal, a transmitter (3) a receiver (4) and a controller (5). The interrogation signal contains angle modulation and amplitude modulation such that the amplitude modulation encodes the interrogation signal with information for communication to one or more of the electronic labels (1). The angle modulation is controllably varied so that the interrogation signal has a frequency spectrum which includes sidebands having reduced amplitudes. The system also includes one or more electronic labels (1) locatable within the interrogation field and capable of detecting and decoding the interrogation field so as to recover the information.

摘要： A method and apparatus is disclosed for demodulating, without use of a directional coupler, a base band signal received on a transmission line that connects a transmitter to an antenna. The method includes obtaining a signal from at least one tapping point on the transmission line and mixing the obtained signal with a reference signal associated with a local oscillator of the transmitter. The method includes deriving in-phase and quadrature base-band channels from different tapping points on the transmission line. The in-phase channel is derived from a first tapping point on the transmission line at which the received signal is in-phase with the transmitted signal. The quadrature channel is derived from a second tapping point on the transmission line at which the received signal is 90 degrees out of phase with the transmitted signal.

摘要： A method is disclosed for coding data communication between an interrogator and electronically coded tags. In the method the data is encoded by an active time period of sub-carrier modulation and an inactive time period of no modulation. In the method a characteristic of the modulation such as phase and/or frequency is varied during the active time period to increase a rate at which the data may be communicated. The method is adapted to minimize collisions between the tags arising from the effect of small signal suppression.

The system includes means for singulating the tag in a population of RFID tags and means for extracting from the tag, identity data adapted to uniquely identify the tag. The system further includes means for securely communicating the identity data to a secure database, means for providing authentication data by the database and means for securely communicating the authenticating data to the interrogator. The system also includes means for providing a further comunication between the tag and the interrogator, and wherein at least one stream of data between the tag and the interrogator includes random data generated via a random physical process. The tag and database may each include means for maintaining a count of secure authentications. The count may be separately maintained by the tag and database and may be incremented following each secure authentication. A method for secure communication between an interrogator and an RFID tag is also disclosed.

摘要： A system is disclosed for avoiding and/or minimizing coupling nulls between an electromagnetic field derived from one or more sources and a plurality of randomly oriented RFID tags. The plurality of tags is arranged to move relative to the filed such that no tag is persistently located in a coupling null relative to the field. The or each tag may be translated and/or rotated relative to the electromagnetic field. Alternatively, the electromagnetic field may be translated and/or rotated relative to the tags. In a further aspect coupling nulls may be avoided by orienting a main axis of the or each source of electromagnetic radiation obliquely relative to a direction of movement of the plurality of tags.
