摘要： A system is disclosed for minimizing coupling nulls between an electromagnetic field derived from one or more sources and a plurality of randomly oriented RFID tags, wherein the electromagnetic field is rotated relative to the tags such that no tag is persistently located in a coupling null relative to the field. The source of the electromagnetic field may include a passive antenna or loop that changes its orientation relative to a direction of movement of the tags. The source of the electromagnetic field may further include an active antenna or loop that is electromagnetically coupled to the passive antenna or loop. A method for minimizing coupling nulls between the electromagnetic field and the randomly oriented tags is also disclosed.

摘要： The invention relates to systems for identifying objects, wherein each object has a radio frequency antenna tuned to the F0 frequency and associated with an electronic circuit in such a way that it can be interrogated by an interrogation device comprising a transmitting/receiving radio frequency antenna. The invention is characterized in that the radiofrequency antenna (28) of the interrogation device is configured in such a way that a magnetic field is created, thereby modifying the F0 frequency tuning of the antennae borne by the objects in a direction which tends to realign said frequency towards the F0 resonance frequency. The antenna is thus provided with a winding (32), for example, which is made of wide conductor strips (38) which are connected by a space (40) in between said strips.

摘要： The invention concerns a method for detecting simultaneous transmissions of electronic tags through an interrogation/reading/recording device comprising steps which consist in: (a) transmitting at the beginning of each electronic tag message a particular sequence of signals (90, 92, 94, 96), which is selected from a set of particular sequences; (b) identifying, on receiving messages through the interrogation/reading/recording device, said sequence of signals received at the beginning of each message; and (c) detecting the simultaneous transmission of at least two electronic tags if the identified sequence of signals (98) does not correspond to one of the particular sequences of said set.

摘要： A system is disclosed for secure communication between an interrogator and an RFID tag. 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 for processing articles in a warehousing or merchandising operation wherein information bearing electronically coded labels are attached to the articles to be processed. The system uses the principle of electromagnetic communication in which an interrogator (4) containing a transmitter generates an electromagnetic signal which is transmitted via an interrogator antenna system (2, 3) to electronic labels (5) containing label receiving antennas. The electronic labels (5) are attached to articles as they are processed. Each label antenna receives a proportion of the transmitted energy and operates a reply generation circuit connected either to the label receiving antenna or a separate label reply antenna with the result that an information bearing electromagnetic reply signal is radiated by the label. The interrogator (4) includes an arrangement for detecting the strength of the reply signal which is radiated by the label and for generating a signal which is indicative of the strength of the reply signal.
