Abstract

A device is described that integrates sensors into a housing which can be placed on a human head for measurement of physiological data. The device includes at least one sensor and a reference electrode connected to the housing. A processor coupled to the sensor and the reference electrode receives signals that represent electrical activity in tissue of a user. The processor generates an output signal including data of a difference between an energy level in each of a first and second frequency band of the signals. The difference between energy levels is proportional to release level present time emotional state of the user. The device includes a wireless transmitter that transmits the output signal to a remote device. The device therefore processes the physiological data to create the output signal that correspond to a person'"'"'s mental and emotional state (response).

Claims

1. A device comprising:

at least one sensor and a reference electrode connected to a mounting device;

a processor coupled to the sensor and the reference electrode and receiving signals from the sensor, the signals representing electrical activity in tissue of a user, the processor generating an output signal including data of a difference between a first energy level in a first frequency band of the signals and a second energy level in a second frequency band of the signals, wherein the difference is proportional to release level present time emotional state of the user; and

a wireless transmitter that transmits the output signal to a remote device.
