    摘要: The present invention relates to the field of communication and transmission of signals. In particular, the present invention relates to a new communication and/or modulation method. The present invention also relates to improving channel occupancy. The present specification discloses the adoption of phase transitions/changes in a manner that indicates a code by virtue of their position (timing) in the communication. This is referred to as Phase Position Modulation.

    摘要: The problem to solve is how to extend the operating range of small stackable RFID tags when they are placed in an undesirable orientation. Disclosed is an RFID tag that operates in two modes whereby in a first mode the tag has a short range and in a second mode the tag has a long range. The tag is converted from the first mode short range device into the second mode long range device by placing it close to a coupling device. That is in the second mode the tag becomes a two part RFID tag system (1400) capable of communicating with an interrogator antenna (1407).

    摘要: The present invention relates to the identification of RFID devices that are arranged closely together and placed on shelving for logistical and storage purposes. Furthermore, the aspects of the present invention relate to an arrangement and/or layout of antenna coils for example in an interrogator. There is disclosed a RFID interrogator and/or method of interrogating comprising an antenna, when activated, being adapted to radiate an interrogation signal in a first area, means adapted to shift the antenna within a second area, the second area being larger than the first area. The antenna may be mechanically moveable.
