Claims
- 1. A movement monitor comprising:
- movement detecting means for detecting movement of a biological body and outputting a corresponding movement signal that varies in accordance with the movement;
- converting means for converting the movement signal into a digital signal;
- storing means for storing the digital signal converted by the converting means;
- movement signal calculating means for frequency-processing the digital signal stored in the storing means to obtain a set of movement components representing frequency versus power of the movement signal;
- extracting means for extracting a selected component from the movement components; and
- calculating means for calculating a characteristic of the movement of the biological body based on the selected movement component extracted by the extracting means.
- 2. A movement rate monitor comprising:
- movement detecting means for detecting movement of a biological body and outputting a corresponding movement signal which varies in accordance with a rate of the movement;
- calculating means for frequency-processing the movement signal to obtain a spectrum of frequency components of the movement signal;
- extracting means for extracting a selected component from the frequency components contained in the spectrum; and
- movement rate calculating means for calculating movement rate of the biological body based on the selected component extracted by the extracting means.
- 3. A movement rate monitor according to claim 2, further comprising converting means for converting the movement signal into a digital signal; and storing means for storing the digital signal converted by the converting means; wherein the calculating means frequency-processes the digital signal stored in the storing means to obtain the spectrum of frequency components of the movement signal.
- 4. A movement rate monitor according to claim 2, wherein the biological body is a human, the movement detecting means includes means for detecting movement associated with running, and the movement rate calculating means includes means for determining distance based upon a movement stride and a calculated movement rate.
