Distance meter
First Claim
1. A method (800) for measuring the distance covered by a person, characterised in fastening to the person (101) a magnetic sensor (212) with substantially stationary direction relative to the person, monitoring (808) any deviation of the magnetic sensor relative to the magnetic field (304) external to the sensor, and counting the times (812) the deviation of the magnetic sensor relative to the external magnetic field exceeds a set limit value.

Abstract
The invention relates to a method (800), a sytem (100) and a device (102) for measuring the number of laps and/or the distance covered by a person during his/her performance. The invention relates particularly to a distance meter (102) to be worn by the user, which measures the distance covered by the object and comprises a magnetic sensor (212) for determining the direction of a magnetic field (304) external to the sensor relative to the sensor (212). The distance meter (102) to be worn by the user in accordance with the invention also comprises a counter (207), whose value is increased when the measured deviation of the magnetic field exceeds a preset limit, i.e. in the situation where a fitness trainer following a given track turns and starts moving into another direction on the track.

- 6. A distance meter (102) for measuring the distance covered by an object, characterised in that the distance meter (102) is a wearable distance meter, and that it comprises a magnetic sensor (212) for determining the direction of the magnetic sensor (212) relative to a magnetic field (304) external to the sensor (102), and also a counter (207), and that the wearable distance meter (102) is arranged to decrease the value of the counter (207) when the deviation of the magnetic sensor (212) relative to an external magnetic field (304) exceeds the set limit value.
