摘要： Apparatus and methods are disclosed for detecting RFID devices, such as when detecting livestock. Transmitters generate cyclic patterns of RF electric field to energise RFID devices for detection. The cyclic patterns include transmitting phases to energise and silent phases to allow half-duplex (HDX) RFID devices to respond. These phases can be individually extended by the control processor when the system detects an RFID device, to give time for reading to be completed. Multiple transmitters have their phases synchronised, so that HDX devices continue to be readable, by means of a shared synchronisation signal which may - characterise every transmitting phase and/or every silent phase, so that plural transmitters quickly fall into synchronicity, and/or - characterise a fixed-duration pulse pattern, used for synchronisation, at its onset rather than in its silent phase.

摘要： An antenna system suitable for the detection of livestock (11) carrying coding electromagnetic signal emitters, the system comprising first and second antenna loops for positioning adjacent a detection path, e.g. a livestock race (10), the first of the loops (1) lying along one side of the detection path, and the second of the loops (2,3) having arch portions (3) which traverse above or below the detection path, and side portions (2) lying alongside the detection path in the form of wings angled relative to the arch portions, such that a three-dimensional detection field (7,8,9) is produced without the need for a third antenna, a phase shift between the loops, or loop multiplexing.
