Abstract

A method and a device for protecting a person from electric shock includes detecting a physical-medical factor by means of a sensor device ( 6 ) carried on the body ( 4 ) of the person; evaluating the physical medial factor, which has been detected by the sensor device ( 6 ) as sensor data ( 20 ), by means of an evaluation device ( 8 ) to discover whether a risk from a body current (I B ) is to be anticipated; and switching off a power supply ( 12 ), which is allocated to the person and causes the possible body current (I B ), by means of a switch-off device ( 10 ) if this risk exists.

First claim

1 . A method for protecting a person from electric shock, the method comprising the steps:
detecting a physical-medical factor by a sensor ( 6 ) carried on the body ( 4 ) of the person, evaluating the physical medial factor, which has been detected by the sensor ( 6 ) as sensor data ( 20 ), by a computer ( 8 ) to discover whether a risk from a body current (I B ) is to be anticipated, switching off a power supply ( 12 ) allocated to the person and causing the possible body current (I B ) by the switch ( 10 ) if this risk exists.

2 . The method according to claim 1 , wherein one or several of the following physical-medical factors are detected: acceleration, heart rate, blood pressure, body temperature.

3 . The method according to claim 1 , further including merging the sensor data ( 20 ) of the physical-medical factors detected by different sensors ( 6 ).

4 . The method according to claim 1 ,wherein the sensor data ( 20 ) is evaluated for predictive detection of a possible body current (I B ) residing above a normatively determined let-go threshold.

5 . The method according to claim 1 , wherein the evaluation takes place using digital signal-processing algorithms.

6 . The method according to claim 1 ,wherein the transfer of sensor data takes place via a wired or wireless connection using a sensor-data transmitter ( 14 ).

7 . The method according to claim 1 , wherein the allocation and switching-off of the power supply ( 12 ) takes place via a wired or wireless connection using a switch-off transmitter ( 16 ).

8 . A device ( 2 ) for protecting a person from electric shock, the device ( 2 ) comprising: a sensor carried on the body ( 4 ) of the person for detecting a physical-medical factor, a computer ( 8 ) for evaluating the physical-medical factor detected by the sensor ( 6 ) as sensor data ( 20 ) to discover whether a risk from a body current (I B ) is to be anticipated,
a switch ( 10 ) for switching off a power supply ( 12 ) allocated to the person and causing the possible body current (I B ) if this risk exists.

9 . The device ( 2 ) according to claim 8 , including one or several of the following sensors ( 6 ): acceleration sensor, heart rate sensor, blood pressure monitor, body temperature sensor.

10 . The device ( 2 ) according to claim 8 ,wherein the computer ( 8 ) is configured for merging the sensor data ( 20 ) of the physical-medical factors detected by different sensors ( 6 ).

11 . The device ( 2 ) according to the claim 8 , wherein the computer ( 8 ) is configured for predictive detection of a possible body current residing above a normatively determined let-go threshold.

12 . The device ( 2 ) according to claim 8 , wherein the computer ( 8 ) is configured for evaluating the sensor data ( 20 ) using digital signal-processing algorithms.

13 . The device ( 2 ) according to claim 8 , wherein a sensor-data transmitter is provided ( 14 ) for a wired or wireless transfer of the sensor data ( 20 ).

14 . The device ( 2 ) according to claim 8 , wherein a switch-off-signal transmitter ( 16 ) for allocating and switching off the power supply ( 12 ) by a wired or wireless transfer method.
