Abstract: A biological signal measurement system includes a biological signal measurement apparatus and a data analysis apparatus. The data analysis apparatus generates a stimulation signal and wirelessly transmits the stimulation signal to the measurement apparatus. The measurement apparatus measures a biological signal of a subject responding to the stimulation. The measurement apparatus acquires a trigger signal corresponding to the stimulation signal, and utilizes a synchronous sampling circuit to synchronize and sample the trigger signal and the biological signal, generating a synchronously sampled data set. The measurement apparatus transmits the synchronously sampled data set to the data analysis apparatus. The data processing apparatus performs data processing on the received biological signal and trigger signal within the synchronously sampled data set to time-align the biological signal with the trigger signal.

Abstract: Provided is an earphone in which electroencephalogram electrodes come into close contact more readily when worn. An earphone includes a housing having elasticity on at least one end portion side outer layer, a speaker accommodated inside the housing, and an eartip that is fixed on the end portion side of the housing having the elasticity, and that includes a sound conduit portion through which sound from the speaker passes, and an elastic electrode that performs sensing of an electroencephalogram of a wearer.

Abstract: A method and apparatus enabling the distribution of hyper-relevant advertising to consumers who have confirmed interests in specific content, products, and services is described. Users define “who they are” and “what they want” in a spontaneous, guided, voluntary disclosure of rich, candid, personal information conceived to attract individuals who seek or share common relationships, experiences, objectives, skills, knowledge, acquaintances, interests, needs, or desires for mutual gain. The information is converted into encrypted user codes; these codes are used to generate precisely controlled electronic encounters, the creation and delivery of highly personalized hyper-relevant advertising, and the gathering of amounts of research data through the ad hoc interaction of unique mobile devices.
