PACE MEASURING APPARATUS, ELECTRONIC APPLIANCE AND PACE MEASURING METHOD
Document Type and Number:
WIPO Patent Application WO/1997/015028
Kind Code:
A1
Abstract:
Body motions include the second harmonic conspicuous during running and the third harmonic conspicuous during walking. Assuming a reference signal to be a high-level line spectrum appearing, for example, in a region above 100/min, both running and walking paces can be found by checking whether the reference signal is the second or the third harmonic. The reference signal is judged as the second or the third harmonic if a high-level signal exists in the proximity of 1/3 or 2/3 of its frequency. If a high-level signal does not exist in the frequency band, the reference signal itself is considered as the second harmonic.
