Patent ID: 8540630

Claim:
A method of synchronizing a user's biosignal data received from a plurality of measurement devices, comprising: transmitting a time set command to each of the plurality of measurement devices; receiving the user's first biosignal data from each of the plurality of measurement devices, the first biosignal data including a time axis and the time axis including a measurement start time and a measurement termination time; comparing the measurement start time and the measurement termination time with a standard time; and generating second biosignal data from corrected first biosignal data, corrected by referring to the standard time, when the comparison results in an error; and synchronizing the second biosignal data and generating third biosignal data, wherein each of the plurality of measurement devices receives the time set command and generates the first biosignal data, and wherein the measurement start time causes the beginning of the measuring of the biosignal data, and the measurement termination time causes, or is caused by, the completion of the measuring of the biosignal data.
