Abstract
A method for determining a heartbeat rate of a user from an acoustic heartbeat signal, a heartbeat rate measuring device, and a mobile device are described.
Claims24
A method for determining a heartbeat rate of a user from an acoustic heartbeat signal, the method comprising:
- detecting the acoustic heartbeat signal in an ear of the user,
- sampling the heartbeat signal with a predefined sampling rate,
- providing a plurality of heartbeat rate values,
- correlating the sampled heartbeat signal with each of the plurality of heartbeat rate values, and
- determining the heartbeat rate value with the best matching correlation as the heartbeat rate.
2 more elements
A heartbeat rate measuring device, comprising:
- a microphone adapted to detect an acoustic heartbeat signal of a user in an ear of the user,
- a sampling unit adapted to sample the heartbeat signal with a predefined sampling rate, and
- a correlation unit providing a plurality of heartbeat rate values, the correlation unit being adapted to correlate the sampled heartbeat signal with each of the plurality of heartbeat rate values, and to determine the heartbeat rate value with the best matching correlation.
A mobile device comprising a heartbeat rate measuring device, the heartbeat rate measuring device, comprising:
- a microphone adapted to detect an acoustic heartbeat signal of a user in an ear of the user,
- a sampling unit adapted to sample the heartbeat signal with a predefined sampling rate, and
- a correlation unit providing a plurality of heartbeat rate values, the correlation unit being adapted to correlate the sampled heartbeat signal with each of the plurality of heartbeat rate values, and to determine the heartbeat rate value with the best matching correlation.
