- Coil is connected to the Kunststoffgußteil 34 solder pads, which will be discussed in connection with the description of Fig. 1 1 and 12, via two wires 40 and 42, which are preferably made of copper, and causes a reinforcement of the RFID Chip emitted signal.
- the coil 38 is arranged in the direction of the marked object 28 above the RFID chip.
- locking elements On the outside of the part 30 and coming into contact with this part of the inside of the part 32 locking elements can be advantageously provided, which cause the two parts when mating together in one or more detent position (s) lock together.
- a simple cylindrical rod core 36 is provided instead of the shell core described above. It is advantageous in such an embodiment that the production compared to a pot core is much easier and less material is needed to achieve similar results in the transmission and reception performance.
- the rod core 36 can be made of any material, but is preferably made of soft magnetic material, in particular a soft magnetic ferrite.
- the quasi cover for the part 30 forming part 32 is a recess 44 which serves to receive an adhesive drop 46.
- a recess 44 is provided which serves to receive an adhesive drop 46.
- the rod core 36 can be securely attached to the part 32, without the adhesive used, which is for example silicone, led to a significant increase in the distance of the rod core and bottom.
- the rod core and thus the coil should namely be brought as close to the bottom of the part 32 and thus to the outside of the marking element, so that they protrude substantially from the surface of the marked object.

- the coil 38, rod core 36 and plastic casting 34 existing assembly is inserted into the parts 32, in which then the part 30, 32 is inserted.
- the coil on the core is preferably initially only wound so that it remains displaceable, or the coil is wound separately and only then pushed onto the core. This can be achieved that after coupling the coil with the RFID chip by moving the coil, the resonance frequency for the correct operation of the RFID chip can be adjusted. After setting the resonance frequency, the coil can then be fixed, for example by immersion in resin or sticking on the core.
- Fig. 8 shows a perspective view of the situation shortly before the pressing of the marking element, of which only the part 32 can be seen here, in an object to be marked 28.
- a receiving bore for the marking element is introduced into the object 28 and the marking element so dimensioned and designed so that it is held by press fit in the receiving bore.
- the marking element has a
- the parts 30 and 32 of the marking element are preferably made of a plastic whose thermal expansion coefficient is greater than that
- Thermal expansion coefficient of the object to be marked in particular greater than the thermal expansion coefficient of steel or stainless steel or titanium.
- Preferred materials for parts 30 and 32 are e.g. Polyetheretherketone (PEEK), polymerizable acrylate or methacrylate and mixtures of polymerizable acrylates and methacrylates, in particular by pressure and / or temperature-curing plastics.
- the marking element may have an elasticity such that its cross-sectional area when pressed into a receiving bore by 0.5 to 20%, preferably about 1 to 10%, more preferably about 2 to 4% can be reduced by compression.
- a marking element with such properties can of course also be created by the fact that the chip and the coil are poured into a suitable plastic, instead of being arranged in the described, consisting of the parts 30 and 32 two-piece sheath ,
- FIG. 9 shows a coil designated in its entirety by 50, which has different winding axes for improved radiation of the signal of an RFID chip in different directions and is wound onto a rod core 52.
- Two connecting wires 54 and 56 allow the connection of such a coil with a RFID chip as described above. The production of such a coil is relatively simple.
- a spool core 60 shown in FIG. 10 may be used, which has at one end a plurality of sections 62, 64 and 66 pointing in different directions. On each of these sections, a coil is wound, wherein all coils are wound from a common wire and two connecting wires 68 and 70 are provided.
- Fig. 10 shows only one way of such an arrangement, with other arrangements and an increase in the number of
- the bonding of the coil wires to the RFID chip is not trivial due to the small dimensions of the RFID chip.
- the RFID chip on a
- FIGS. 11A and 11B show two possible embodiments of such printed circuit boards 80 and 80 ', it being noted that the arrangement of the soldering pads 84 and 86 or 84' and 86 'and of the RFID chip 82 as well as the shape of the circuit board 80 or 80 'can be adapted to the requirements of each marking element used.
- the connection of the coil wires to the RFID chip is facilitated and simplified by using such circuit boards.
- an RFID chip 90 may be provided to embed the RFID chip 90 in a plastic casting 92 or 92 'and with two solder pads 94 and 96 or 94 'and 96' arranged on the surface of the plastic casting. This ensures, on the one hand, that the RFID chip and the interconnect between solder pads and RFID chip are completely protected. On the other hand, as already mentioned above, the connection of the coil with the RFID chip and thus the production is simplified. Again, numerous variations of the arrangement of the solder pads and the RFID chip are possible.
- the shell or rod core together with coil is then preferably glued to the circuit board or the plastic casting.
- the RFID chip together with glued rod core and coil can then, as shown in Fig. 7, are arranged in a two-part shell.
- Marking elements of the type in question can be used to implement a system and with the system a method for marking any non-living or living objects, in particular for object control and object management, whereby a set of marking elements is produced and each RFID chip is given an individual, unique identification number is assigned.
- the numbers are stored in a database.
- Manufacturers of any products can then purchase a set of corresponding marking elements for marking.
- customers read the marking elements at least partially by means of appropriate readers and can check on a request either from the manufacturer or a third party, whether it is the purchased product is an original product of the manufacturer.
- the system allows for many other modifications and refinements. This allows customers to use the system not only to verify that they are genuine, but alternatively or additionally, to manage the objects owned by the customer. For example, the system allows to capture with little effort how frequent a particular surgical procedure
- Instrument was used. If the customer has e.g. Having acquired 100 instruments of the same type, he can easily use the system to ensure that the instruments are used equally frequently and wear evenly.
- the marking element according to the invention already ensures a very good readability of the radiated signal through its coil, it has been found that when metallic objects are equipped with such marking elements, eddy current formations can occur in the marked object which disturb the reading of the signal. To avoid such eddy currents it is already known to bring separate slots in the object to be marked, but this requires a separate step.
- the invention therefore proposes to make the necessary for the introduction of the marking element bore as shown in FIGS. 13 and 14 in an edge region of the object to be marked so that the drilling axis less than a Bohrradius from the transverse to the direction of
- Drill axis seen nearest edge of the object is removed.
- the drilling axis should maintain a distance to this edge, which is so large that a pressed into the hole marking element is still held securely in the hole.
- angular e.g. to introduce quadritic receptacles for correspondingly shaped marking elements in an analogous manner into an object to be marked, so that then a corner of a corresponding angular marking element projects laterally out of the object.
- round holes are preferred in cross-section.
- a portion 100 e.g. The handle of a surgical instrument is shown once in side view (FIG. 13), once in plan view (FIG. 14), into which a marking element 102 is inserted.
- This introduction of the bore results in a slot in the outer wall of the object 100, which can reduce the occurrence of disturbing eddy currents when reading out an RFID chip provided in the marking element 102 or can even completely prevent it.
