Abstract

A method for making safe the use of at least one hand-held power tool includes providing at least one item of safety information using at least one evaluation unit of an electronic safety device. The at least one item of safety information is based on at least one application-specific characteristic quantity. The electronic safety device is configured to be fastened to an extremity of a user using a fastening unit.

Claims

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

providing at least one item of safety information using at least one evaluation unit of an electronic safety device,

wherein the at least one item of safety information is based on at least one application-specific characteristic quantity, and

wherein the electronic safety device is configured to be fastened to an extremity of a user using a fastening unit.

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

wirelessly exchanging data with the at least one hand-held power tool using the at least one evaluation unit.

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

evaluating an identifier of the at least one hand-held power tool using the at least one evaluation unit.

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

evaluating the at least one application-specific characteristic quantity, in relation to at least one of (i) a data history and (ii) a reference quantity, using the at least one evaluation unit.

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

evaluating data using at least one external evaluation unit in order to provide the at least one item of safety information; and

transmitting at least one evaluation result to the at least one evaluation unit.

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

sensing at least one of (i) a position and (ii) an orientation of the fastening unit using at least one position and/or orientation sensor unit; and

transmitting the at least one of (i) a position and (ii) an orientation to the at least one evaluation unit.

7. The method according to claim 1, wherein:

sensing using a machine sensor at least one application-specific characteristic quantity of the hand-held power tool; and

transmitting the at least one application-specific characteristic quantity to the at least one evaluation unit.

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

exchanging data using the at least one evaluation unit with at least one appliance database.

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

evaluating servicing data using the at least one evaluation unit.

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

transmitting the at least one item of safety information, using the at least one evaluation unit, to at least one output unit of the safety device to output to a user.

12. The method according to claim 4, wherein the at least one application-specific characteristic quantity is at least one oscillation pattern.

11. An electronic safety device for making safe the use of at least one hand-held power tool comprising:

at least one fastening unit configured to fasten to an extremity of a user;

at least one evaluation unit configured to provide at least one item of safety information,

wherein the at least one item of safety information is based on at least one application-specific characteristic quantity, in a case of application of the at least one hand-held power tool.
