The encrypted communication increases the data security during communication via the communication network 180.
  • the token 156 has the electromechanical coupling device 170, which is designed for preferably form-fitting mechanical coupling to the receiving opening 159 of the hand-held device 100 or one of its components 102, 110, 152.
  • the electromechanical coupling device 170 of the token 156 is defined by its outer shape, which is designed inversely to the inner shape of the receiving opening 159 .
  • the token 156 can be configured to control the operation of said handset 100 by means of the processor 166 (and optionally the cryptography unit 168 using cryptographic communication) when the electromechanical coupling device 170 is mechanically coupled to a receiving opening 159 of the handset 100 . More specifically, processor 166 of token 156 can control handset 100 to: that the desired processing task is carried out as intended. For example, the processor 166 of the token 156 can specify which torque is applied by a drill bit of a hand-held device 100 embodied as a drill to a subsurface 104 in which a borehole is to be drilled.
  • the token 156 can advantageously be designed for user-related control of the hand-held device 100, in particular on the basis of a personalized authorization profile for the user.
  • the token 156 can be provided with an identification device 172 which is designed to identify a user of the token 156 .
  • the identification device 172 is formed by a sensor 174 embodied, for example, as a fingerprint sensor, and that part of the processor 166 that identifies the user from the sensor data ascertained by means of the sensor 174, for example by a pattern comparison with reference data. More precisely, the sensor 174 is embodied, for example, as a fingerprint sensor on which a user places a finger for identification. The sensor 174 can therefore advantageously be attached in a surface area of the token 156 .
  • the sensor 174 can then determine whether the data sensed by the sensor 174 indicates that the user is a legitimate or authorized user, or what the user is. This determination can be carried out by comparing the data recorded by sensors with sensor reference data (for example a fingerprint of an authorized user stored in a database).
  • the processor 166 may be configured to control the operation of the handset 100 coupled to the token 156 in accordance with the user authorization profile of the token 156 user.
  • the processor 166 can be designed to enable the operation of the handheld device coupled to the token 156 only if a user identification carried out in advance using the token 156 has led to the result that an identifying user can operate the handheld device 100 is authorized.
  • the processor 106 of the token 156 can therefore be designed to permit, set and/or prevent use of the hand-held device 100 by the user based on the personalized authorization profile when it is coupled to the hand-held device 100 .
  • the token 156 can, for example, be in the form of a plug-in element for plugging into the receiving opening 159 .
  • each token 156 can be in the form of a circular disc with a diameter in a range from 2 cm to 4 cm and can therefore be easily handled by a user and inserted into a hand-held device 100 in a space-saving manner.
  • the electromechanical coupling device 170 of the token 156 is designed to detachably couple the token 156 to the hand-held device 100 .
  • a user can use a token 156 (assigned to him, for example) in combination with different handheld devices 100 in succession, with the selection of an addressed handheld device 100 simply being possible by mechanically inserting the electromechanical coupling device 170 of the token 156 into an associated receiving opening 159 of a target handheld device 100 or a target component 102, 110, 152 can take place.
  • the token 156 may include one or more sensors 174, including the user identification sensor described above. It is alternatively or additionally possible to equip the token 156 with a gyro sensor, a location sensor and/or a temperature sensor, for example.
  • a gyro sensor can detect when a hand-held device 100 with a token 156 received therein falls and is consequently subjected to a shock. In this case, the hand-held device 100 can be switched off as a precaution in order to avoid injuries to a user and damage.
  • a location sensor e.g. a GPS sensor
  • the use of a hand-held device 100 can (e.g.
  • a location sensor detects that a handset 100 and token 156 is in an unauthorized location for use, the processor 166 of the token 156 may turn off or disable the handset 100 to prevent misuse.
  • a temperature sensor of the token 156 can detect the ambient temperature. If a processing task (e.g. setting a chemical anchor) is only permitted under certain temperature conditions, operation of the hand-held device 100 can be prevented for safety reasons if a temperature condition is not met given the detected temperature sensor data.
  • the token 156 has an energy supply device 176, for example a replaceable battery or a rechargeable battery. Then the token 156 can be operated autonomously. Alternatively or additionally, the token 156 can be supplied with electrical energy by the energy supply device 110 of the hand-held device 100 when the token 156 is received in the receiving opening 159 .
  • FIG. 1 further shows that the token 156 can have a communication antenna 178, for example a WLAN antenna. It is also possible and advantageous for reasons of diversity if the token 156 has multiple communication antennas 178 that support different communication protocols, for example.
  • a communications antenna 178 may be implemented in the form of a planar coil, preferably disposed in a surface area of the token 156 .
  • the token 156 shown has a communication device 119 which can be formed by the communication antenna 178 interacting with a corresponding part of the processor 166 and optionally with the cryptography unit 168 .
  • the communication device 119 is used to communicate the token 156 with one or more communication partner devices 158 via the Communication network 180.
  • This can be, for example, the public Internet, an intranet or a cellular network.
  • the communication network 180 it is possible to use the communication network 180 to form a communicable coupling between the token 156 and an app or other software stored on a portable user terminal of the communication partner devices 158 .
  • the user terminal is a mobile radio device with a user interface with which a user can control and/or monitor the communicatively coupled token 156 and/or a handheld device 100 coupled thereto.
  • a user can also use the user terminal to control and/or monitor the hand-held device 100 from a remote position.
  • a token 156 can connect via an app to the user terminal designed here as a mobile radio device. Data can be downloaded onto the token 156 by means of the user terminal, for example a user profile of a user of the user terminal. It is also possible that the token 156 accesses resources of the user terminal during operation, for example a processor contained therein and/or a camera of the user terminal.
  • the communication network 180 can form a coupling capable of communication between the token 156 and a central control device as the communication partner device 158 .
  • the central control device can be equipped with access rights to a database 132 from which data records can be transmitted to the token 156 .
  • data records can be, for example, a user profile requested by the token 156, an operating data record for executing a processing task with a handheld device 100 mechanically coupled to the token 156, etc.
  • the token 156 can thus be formed by means of the communication device 119 from the central control device or a download a data set to other communicatively coupled nodes of the communication network 180, in particular a data record defining an operational sequence of the hand-held device 100 and/or a data record defining a user profile of a user of the token 156 .
  • data from the token 156 to the control device for storage in the database 132 can be, for example, tracking data that allows a handheld device 100 coupled to a respective token 156 to be tracked.
  • the token 156 can thus be designed to upload a data record, in particular a data record containing operating results and/or operating parameters of an operation of the hand-held device 100, to the control device or another communication-capable coupled communication partner device 158 by means of the communication device 119.
