HEALTH MONITORING DEVICE AND HUMAN ELECTRIC SIGNAL PROCESSING METHOD
First Claim
1. A health monitoring device, comprising:
- a detecting unit for detecting a first electric signal from a human body; and
a processing unit for performing the following steps;
receiving the first electric signal;
performing wavelet transform on the first electric signal, to filter frequency bands thereof which include undesired noises, and then perform reverse wavelet transform to obtain a second electric signal;
combining frequency bands of the first electric signal which include desired primary characteristics and then performing reverse wavelet transform on the combined frequency bands to obtain a third electric signal;
obtaining period information of the second electric signal from the third electric signal, and then re-sampling the second electric signal according to the period information to obtain a fourth electric signal; and
comparing the fourth electric signal with a plurality of electric signal patterns in a database to determine whether the fourth electric signal is an electric signal for healthiness.
