Abstract: A system for recognizing animals in a detection zone (4) wherein the animals are provided with a label (6.i) that responds by transmitting a return signal with information when the label is (6.i) introduced into an electromagnetic interrogation field, provided with at least a transmitting and receiving system (2) for transmitting the electromagnetic interrogation field in the detection zone (4) and for receiving a return signal from a label (6.i) located in the detection zone (4), whereby the transmitting and receiving system (2) is provided with a plurality of antennas (8.i) for receiving a return signal from at least one label (6.i) present in the detection zone (4) wherein the antennas (8.i) are designed and arranged to discretely receive electromagnetic signals which come from mutually different subzones (4.i) wherein the subzones (4.i) in combination from the detection (4) zone.

Abstract: A motion detector, in particular suitable for animals, comprising at least one motion element, wherein an element movable within a predetermined area is located, which brings about an electrical connection in at least one position, wherein the movable element is a magnetic element, which can move along a path of travel formed by a cavity in the motion element, and wherein, near the path of travel, at least one magnetically sensitive switching element is placed, which can be influenced by the magnetic element.
