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 radio frequency identification (RFID) tag and a method and system for communicating with the RFID tag. The RFID tag includes a first and second structure respectively holding first data and second data that is complementary to the first data. The RFID tag does not include a microchip. An electromagnetic radio frequency signal is transmitted from an interrogator to the RFID tag. The interrogator receives, from the RFID tag, a response signal including third data being the first data or a combination of the first data and the second data. The interrogator extracts the third data from the response signal. A default value equal to the combination of the first data and the second data is stored in the interrogator. If the interrogator determines that the third data is unequal/equal to the default value, then a screen of the interrogator displays that the RFID tag is enabled/not enabled.

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 biometrically activated radio frequency identification (RFID) tag including a fingerprint detection matrix, an antenna control circuit, and a biometric identification chip. The fingerprint detection matrix acquires biometric data indicative of a user's identity and passes it to the biometric identification chip. The biometric identification chip compares the biometric data acquired by the fingerprint detection matrix to biometric data stored thereupon. The antenna control circuit activates the RFID tag selectively dependent upon the result of the comparison of the acquired and stored biometric data.

Abstract: The present invention is directed to a system for controlling, in a moving vehicle, wireless communications between a local and a remote party and more particularly to prevent any conversation in vehicles travelling above a predefined speed without cutting off wireless communication. If a wireless communication is detected and if the vehicle speed exceeds a first predefined speed limit, the wireless communication is suspended. When the vehicle speed decreases below a second predefined speed limit, the suspended wireless communication is re-established. The system comprises a wireless communication manager unit connected to both a conventional mobile communication system and a conventional free hand kit, the free hand kit being also connected to the mobile communication system.
