Abstract: A chromatic display-type biofeedback system and method using brain waves are disclosed. After the brain waves generated from the subject, which are indicative of anxious or relaxed psychological state, are recoded by himself or herself, the subject transforms each psychological state into a chromatic bar represented by a desired color. And then, when the subject measures his or her brain waves, a specific color is displayed on a monitor, so that the subject may verify the present psychological state and repeatedly remind him or her of a color designated as a relaxed state to induce the reaching of the relaxed state. At that time, after a psychological state of the subject is verified by modeling the brain waves using a Hidden Markov Model (HMM) which is used in a statistical signal process, the results is displayed as a chromatic bar designated by the subject on a monitor, so that conversion of the relevant psychological state can be rapidly and easily achieved.

Abstract: A radio frequency power combiner includes a plurality of transmission lines connecting a plurality of input terminals to an output terminal. An RF switch is positioned between each of the input terminals and a transmission line connecting the output terminal to the input terminal. The electrical length between each RF switch and the output terminal is preferably one half of a wavelength at a central frequency, which may be realized by two transmission lines of different impedances in each path, each a quarter wavelength long. When the switches are on, the signal power applied to all of the input terminals is combined at the output terminal. When any given switch is turned off, the RF power incident to the switch is reflected, and the transmission lines connected between that switch and the output terminal appear as an open circuit. The power combiner can also operate as a power divider.
