Method for making safe the use of at least one hand-held power tool

1. A method for making safe the use of a hand-held power tool, comprising:

receiving, with a processor of an electronic safety device, an application-specific characteristic quantity from a machine sensor of the hand-held power tool configured to measure the application-specific characteristic quantity, application-specific characteristic quantity relating to at least one of a state of the hand-held power tool and a state of a working environment of the hand-held power tool;

receiving, with the processor of the electronic safety device, an identifier of the hand-held power tool from the hand-held power tool;

retrieving, with the processor of the electronic safety device, reference data assigned to the identifier from an appliance database;

comparing the application-specific characteristic quantity with the reference data; and

outputting, with an output device of the electronic safety device, at least one item of safety information using to the user in response to the comparison of the application-specific characteristic quantity with the reference data indicating infringement of a safety criterion,

wherein the electronic safety device has a fastener configured to fasten the electronic safety device to an extremity of a user.

2. The method according to claim 1 , further comprising:

wirelessly exchanging data between the hand-held power tool and the processor of the electronic safety device.

3. The method according to claim 1 , further comprising:

evaluating the application-specific characteristic quantity in relation to a data history.

4. The method according to claim 1 , further comprising:

comparing the application-specific characteristic quantity with the reference data using a processor of an external device; and

transmitting a result of the comparison of the application-specific characteristic quantity with the reference data from the external device to the processor of the electronic safety device.

5. The method according to claim 1 , further comprising:

sensing at least one of (i) a position and (ii) an orientation of the fastener using at least one of a position sensor and an orientation sensor of the electronic safety device; and

transmitting the at least one of (i) the position and (ii) the orientation to the processor of the electronic safety device.

6. The method according to claim 1 , further comprising:

retrieving, with the processor of the electronic safety device, servicing data assigned to the identifier from the appliance database.

7. An electronic safety device for making safe the use of a hand-held power tool comprising:

a fastener configured to fasten the electronic safety device to an extremity of a user;

an output device; and

a processor configured to:

receive an application-specific characteristic quantity from a machine sensor of the hand-held power tool configured to measure the application-specific characteristic quantity, application-specific characteristic quantity relating to at least one of a state of the hand-held power tool and a state of a working environment of the hand-held power tool;

receive an identifier of the hand-held power tool from the hand-held power tool;

retrieve reference data assigned to the identifier from an appliance database;

compare the application-specific characteristic quantity with the reference data; and

operate the output device output at least one item of safety information in response to the comparison of the application-specific characteristic quantity with the reference data indicating infringement of a safety criterion.

8. The method according to claim 3 , wherein the application-specific characteristic quantity is at least one oscillation pattern.
