Abstract

Technology for transmitting and receiving a biosignal based on a pattern related to the biosignal and a feature point included in the biosignal. A biosignal transmitter includes a biosignal obtaining unit configured to obtain a biosignal comprising a plurality of unit signals, a parsing unit configured to parse the biosignal to extract a first unit signal of the plurality of unit signals, a pattern obtaining unit configured to obtain a pattern related to the biosignal based on the first unit signal, and a transmitting unit configured to transmit information related to a feature point of the first unit signal based on the first unit signal and the pattern.

Claims

1. A biosignal transmitter comprising:

a biosignal obtaining unit configured to obtain a biosignal comprising a plurality of unit signals;

a parsing unit configured to parse the biosignal to extract a first unit signal of the plurality of unit signals;

a generating unit configured to generate a pattern that correlates to the first unit signal in response to a determining of which pattern, of a plurality of patterns, correlates to the first unit signal indicating that a correspondable pattern has not yet been generated; and

a transmitting unit configured to;

transmit the generated pattern that correlates to the first unit signal when the determining of which pattern correlates to the first unit signal indicates that the correspondable pattern has not yet been generated,

transmit information related to a feature point of the first unit signal when the first unit signal correlates to a predetermined pattern, and

transmit the first unit signal when the first unit signal does not correlate to the predetermined pattern,

wherein the information related to the feature point comprises an amplitude and position of a peak in the first unit signal.

2. The biosignal transmitter of claim 1, wherein the parsing unit is further configured to extract the first unit signal by detecting respective peaks of the plurality of unit signals, and parsing the biosignal based on positions of the peaks.

3. The biosignal transmitter of claim 1, further comprising:

a pattern determining unit configured to determine a pattern, of the plurality of patterns, related to the biosignal based on the first unit signal, including the determining of which pattern of the plurality of patterns correlates to the first unit signal, wherein the generating unit is comprised in the pattern determining unit.

4. The biosignal transmitter of claim 3, wherein the determining unit is further configured to:

obtain a first pattern, of the plurality of patterns determined correspondable with the first unit signal, stored in a storage space provided in advance;

determine whether the first pattern corresponds to a waveform of the first unit signal; and

determine that the first pattern correlates to the first unit signal based on a result of the determining of whether the first pattern corresponds to the waveform of the first unit signal.

5. The biosignal transmitter of claim 3, wherein the generating unit is further configured to:

receive a predetermined number of unit signals from the parsing unit; and

calculate an average of the predetermined number of the unit signals to generate the pattern that correlates to the first unit signal.

6. The biosignal transmitter of claim 1, wherein the transmitting unit is further configured to:

calculate a correlation between the first unit signal and the predetermined pattern;

extract the feature point of the first unit signal in response to the correlation meeting a predetermined threshold; and

transmit the information related to the feature point.

7. The biosignal transmitter of claim 6,

wherein the transmitting unit is further configured to transmit the first unit signal in response to the correlation being lower than the predetermined threshold value.

8. The biosignal transmitter of claim 1, wherein the biosignal has a periodicity, the plurality of unit signals comprise the first unit signal and a second unit signal, and a waveform of the first unit signal and a waveform of the second unit signal are classified as an identical pattern.

9. The biosignal transmitter of claim 1, wherein the biosignal comprises an electrocardiogram (ECG), and the pattern depends on a position of an electrode configured to measure the ECG.

10. A biosignal transmitter comprising:

a biosignal obtaining unit configured to obtain a biosignal comprising a plurality of unit signals;

a parsing unit configured to parse the biosignal to extract a first unit signal of the plurality of unit signals;

a pattern determining unit configured to determine a pattern, of a plurality of patterns, related to the biosignal based on the first unit signal, including determining which pattern of the plurality of patterns correlates to the first unit signal and determining whether a correspondable pattern has previously been generated for the first unit signal;

a generating unit configured to generate a pattern that correlates to the first unit signal when the determining of whether the correspondable pattern has previously been generated indicates that the correspondable pattern has not previously been generated; and

a transmitting unit configured to transmit information related to a feature point of the first unit signal, based on the first unit signal and the determined pattern, when a calculated correlation between the determined pattern and the first unit signal meets a predetermined threshold, to transmit the generated pattern when the determining of whether the correspondable pattern has previously been generated indicates that the correspondable pattern has not previously been generated, and to transmit the first unit signal when the calculated correlation between the determined pattern and the first unit signal does not meet the predetermined threshold.
