专利汇可以提供Method and apparatus for hearing by biodetection and biotransduction of radiofrequency energy专利检索，专利查询，专利分析的服务。并且The present invention relates to a method and apparatus utilizing R-F carriers of predetermined frequencies to stimulate the sensation of hearing in human subjects and, more particularly, to a method and apparatus for establishing a peak LC series resonant coupling, at approximately the predetermined R-F carrier frequency, between a signal source and the facial nerve system of the human subject to transmit A-F information modulated onto the R-F carrier to the brain through the ''''facial nerve system,'''' well-defined anatomical network of nerves. More particularly, the modulated R-F signal is capacitively coupled to opposite sides of the head at the periaural and/or stylomastoid region through electrodes. A series inductor is included between the source of R-F signals and each of said electrodes and the inductance of said series inductors is related to the capacitance of the coupling electrodes and the capacitance of the head of the subject so as to tune the R-F signals in peak LC series resonance substantially at the selected carrier wave frequency regardless of changes in the physiology of the subject, said means being a necessary condition for auditory information transfer to the deaf.，下面是Method and apparatus for hearing by biodetection and biotransduction of radiofrequency energy专利的具体信息内容。
