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.

First claim

What is claimed is:

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.
