Abstract

A detection antenna for detecting the coding of a pigeon foot-ring which has a store containing the coding and a ferrite antenna, comprises antenna windings 3 carried by a winding carrier 1, 2 said carrier having an opening 5 in a portion enclosed by the said windings. The ring is read by inserting the pigeon's foot into the opening. This ensures correct alignment of the ring and reading windings 3, ensuring quick and accurate transfer of the stored data. <IMAGE>

Description

ANTENNA The invention relates to a detection antenna for detecting the coding of pigeon foot-rings.
Foot-rings for pigeons usually carried on the pigeon's leg are known, which have a ferrite antenna wound in the form of a ring. Also in the foot-ring are two stores one of which is erasable and the other non-erasable. In the non-erasable store a code is contained identifying the respective pigeon. This code can be read off by a detection antenna, whereupon reader apparatus associated therewith then generates a random code which is emitted by the detection antenna, detected by the ferrite antenna and stored in the erasable store. This procedure is described in DE-PS 42 40 879.
For reading off the identification code and for introducing the random code it is known to employ antennae which lie under a covering and the windings of which lie in a horizontal plane. The pigeons are seized by both the handler's hands and put onto such a detection antenna. It has been found that in some cases there is an unreliable reading of the identification code since the fields of the detection antenna and the ferrite antenna are not lying at the optimum angle with respect to one another. If the pigeon splays its foot or this is moved away from the detection antenna, the fields of the antenna and the ferrite antenna are in a particularly poor position with respect to one another.Because of this unfavourable relative position of the fields the reading of the identification code becomes unreliable, and the reading-off must often be repeated a number of times until a satisfactory reading of the identification code has been achieved.
Another disadvantage is that the splayed position of the toes is an unusual posture for the pigeon which the creature resists. In many cases the pigeons try to pull the leg away, which again means that the foot-ring is no longer lying within the reading range of the detection antenna. If the pigeon's foot is pressed too firmly against the plate-like antenna the pigeon may be injured.
Still greater uncertainties arise in the introduction of the random code into the erasable store on the foot-ring. After the reading of the identification code by the detection antenna the random code is emitted only once. If the fields of the two antenna are at an unfavourable angle to one another, then the random code is not or is only incompletely detected by the ferrite antenna. The results of an air race can therefore be called in question.
The problem exists of constructing the detection antenna so that an optimum alignment is guaranteed between the fields of the antenna and the ferrite antenna on the foot-ring.
It is an object of the present invention to overcome the problems referred to.
According to the present invention a detection antenna for detecting the coding of a pigeon foot-ring which has a store containing the coding and a ferrite antenna, comprises antenna windings carried by a winding carrier, said carrier having an opening in a portion enclosed by the said windings.
Because the winding carrier has an opening in the portion enclosed by the windings, it is possible to introduce the pigeon's foot which is carrying the foot-ring, into the opening until the read-in and read-out station to which the dectection antenna is connected, indicates that the identification code has been emitted by the antenna. In doing this the pigeon's foot is preferably introduced into this opening in the stretched position.
The windings of the detection antenna preferably lie in a substantially vertical plane so that the introduction of the pigeon's foot into the opening corresponds with a natural position of the pigeon. It is not necessary to try reading off the identification code a number of times until the code has been correctly detected by the read-in and read-out station. A first reading-off may be registered satisfactorily. The random code is also introduced into the erasable store without any problem.
Since the fields of the detection antenna and ferrite antenna are aligned at an optimum to one another, the degree of introduction of the ringed foot of the pigeon provides no difficulty.
The invention can be performed in various ways but one embodiment will now be described by way of example and with reference to the accompanying drawing which shows a diagrammatic perspective view of a detection antenna according to the present invention.
As shown in the drawing the detection antenna comprises a winding carrier 2 which extends substantially vertically or is slightly inclined to the vertical, and mounted on a foot 1 which extends horizontally and which together form a T-shape. Within the winding carrier 2 there are a number of antenna windings 3 which therefore lie in a substantially vertical plane. A circular opening 4 is provided in the winding carrier 2 in the portion enclosed by the windings 3. The ringed foot of a pigeon is introduced into this opening 4 so that the identification code contained in the non-erasable store in the foot-ring is read by the detection antenna and the random code is then read into the erasable store on the foot-ring. After the reading-in of the random code the read-in and read-out station to which the windings 3 of the antenna are connected, generates an acknowledgement signal indicating that the read-in and read-out process has been concluded.
The pigeon's ringed foot is then removed from the opening 4.
The opening 4 can extend right through the winding carrier 2, but it is also possible to provide an opening 4 which is closed at one side by a wall 5. In this arrangement the antenna windings 3 are preferably arranged in a plane which extends in the winding carrier 2 at a distance spaced away from the wall 5 and preferably at the edge 6 of the opening 4 remote from the wall 5.
