• a locking cylinder itself consists of a housing and a rotatable cylinder core or cylinder insert.
• Magnetic locks which have several tumblers which then have to be unlocked individually according to the locking code so that the bolt can be actuated.
• Sliding magnets, rotary magnets or wobble pins are known. The way it works is based on the principle of attraction and repulsion. The magnetic pins only unlock when there is a suitable one on the key Opposite pole is present. With the principle of rotary magnets, the pins are turned by the key and release a mechanism if the correct position is available. In the case of so-called wobble pens, various pens have to be brought into the correct position with a magnetic key. so that there is a fit related to a template.
• the disadvantage of magnetic keys is the basic possibility of copying, since the essential functions of the key can be determined and imitated by analysis of the same.

• these jamming transmitters are accommodated outside the building or are brought into the building by people to disrupt the data transmission traffic and installed there at various locations, for example in sanitary facilities.
• the location of such jammers is difficult due to the multiple field distortions within the building and usually requires that the. regular data transmission operations.
• the object of the invention is achieved with a profile lock cylinder with cylinder housing and at least one key-actuatable cylinder core or cylinder insert according to the combination of features according to claim 1, the subclaims representing at least expedient refinements and developments, and with a method according to its definition Claim 12.
• the basic idea of the invention is accordingly to start from a standard profile lock cylinder, according to the invention the pin tumblers can be moved into a release position via electromagnetic actuators located in the cylinder core or in the cylinder, the activation of the actuators preferably taking place wirelessly.
• At least one of the end faces of the cylinder jacket is made of a ceramic material or is positively and / or non-positively and / or cohesively connected to a ceramic cap.
• the outside of the cap can have a driving profile or a driving recess which corresponds to the shape of a suitable key.
• the tumblers are not actuated using the key, but rather the electromagnetic actuator system mentioned above. Only the execution of the rotary movement for adjusting the locking bar in a manner known per se is realized with the aid of the key, i.e. it is possible to use the key as usual.
• the key can be designed as a passive or active transponder key, which is able to send coded information on request that corresponds to a locking authorization.
• the ceramic cap which in addition to its substrate function for electronic components of the Profilschlzyli nders also acts as an advantageous drilling protection, can now be designed as an antenna element or antenna radiator, in which case the dielectric properties of the ceramic are used. Furthermore, an integrated circuit or a hybrid arrangement of electronic components for the decoding of signals and the actuation of the electromagnetic actuators can be introduced into the ceramic.

• the cap can be substantially hemispherical and has e.g. slot-shaped opening for receiving the antenna antenna already mentioned and / or for indirect coupling with the key or the key tip.
• the slot-shaped opening is used for the positive force transmission of the rotational movement with the key after release of the tumblers to the lock bit.
• a cylinder core is designed to accommodate the primary or secondary element mentioned.
• the power supply is designed as a rechargeable battery and embedded in the cylinder core.
• the battery can rotate with the core of the cylinder and is completely in the standard cylinder housing. So it forms the cylinder core of the battery housing, which in turn carries the electronics modules and a special end cap at the ends.
• the control and evaluation electronics are mounted on a flexible wiring carrier, the flexible wiring carrier being accommodated in the space between the two cylinder cores which are separated from one another, so to speak, by folding in a very confined space.

• the lock cylinder carries a miniaturized gyroscope in the cylinder core, i.e. a special motion sensor that detects rotations, shocks and accelerations.
• a system implemented in this way is able to recognize the locked state, the locked state and / or an attempted break-in on the cylinder.
• knocking on the door can be recognized as a sign, for example, for switching on an intercom or video system.

With suitable insulation and targeted overheating, two-speed locking can be ensured with just a single current pulse, since the cooling and reforming takes a few seconds in accordance with the hysteresis of the shape memory alloys. In this way, the power consumption is halved compared to solutions of the prior art.
• the end caps of the electronic cylinder are made of ceramic material. These ceramic caps can contain other functional elements such as contact pins and balls for galvanic contact and for reading out the key data, contact pins and contact balls for galvanically triggering the reset function, contact pins and contact balls for galvanically contacting the electrodes when charging the secondary element and an antenna for transmitting Have radio signals.
• the ceramic is vapor-coated with a load-bearing copper layer and a decorative metal layer above it.
• the cylinder core carries a thin metal plate, which has a very hard carbon layer on both sides due to a carbon nitriding process, which offers the desired protection against drilling attempts.
• the housing is in turn protected by special ceramic rods, which are placed between the locking pins, against drilling open the two internal locking pins.
• the lock cylinder in turn can be mechanically decoupled so that the core directed towards the inside of a door is still movable and thus a rotation of the locking lug is possible, while the core directed towards the front of the door can no longer be unlocked, for example as a result of a power failure.
• the receivers addressed on the process side via the network have at least two active and spaced-apart antennas with a specified directional characteristic and / or sensitivity.
• the necessary and legitimate transmitters for data transmission including the necessary repeaters, are installed or operated at specified locations.

• the stored standard levels and / or standard angle of incidence are compared with the respectively current transmission values, with data transmission being released depending on the degree of agreement from the comparison step.
• the method according to the invention takes advantage of the fact that there is a defined field distribution, particularly within buildings, due to the very specific high-frequency properties there, which is dependent, for example, on the type of building wall material, the arrangement of window surfaces, the formation of metallic door frames, the structure and distribution of metallic pipelines and so on.
• This field distribution and propagation of high-frequency radiation which arises depending on the dielectric and other field-influencing criteria and which of transmission devices that are operated at defined locations, represents a typical non-artificially generated environmental image.
• the transmitting antennas can also have a defined directional characteristic in order to achieve a field distribution image that is typical on the one hand, but on the other hand also to ensure that a sufficient reception field strength is guaranteed at the location of the respective receiving antennas.
• the spaced antennas are each arranged in end caps of cylinder cores of a profile locking cylinder, a first antenna being positioned inside and a second antenna outside the space to be secured by means of a window, a door or the like.
