Ingeborg J Hochmair, Erwin S Hochmair: System for enhancing auditory stimulation and the like. Orrin M Haugen, Thomas J Nikolai, November 2, 1982: US04357497 (152 worldwide citation)

A plurality of the carrier signals are modulated by signals in the audio frequency bands. The carrier signals are transmitted to a receiver having one or more independent channels for receiving and demodulating the transmitted signals. The detected signals are applied to electrodes on a prosthetic d ...

Greater positioning tolerance is permitted in inductively coupled transmitter and receiver tuned circuits by achieving critical coupling therebetween. Critical coupling at a predetermined distance is obtained by selecting the appropriate quality, Q, of the tuned circuit, whereby the quality of the t ...

Ingeborg J Hochmair, Erwin S Hochmair: Multi-frequency system and method for enhancing auditory stimulation and the like. Flehr Hohbach Test, August 18, 1981: US04284856 (90 worldwide citation)

A plurality of carrier signals are modulated by pulses corresponding to signals in audio frequency bands. The carrier signals are transmitted to a receiver having independent channels for receiving and demodulating the transmitted signals. The detected pulses are applied to electrodes on a prostheti ...

Ingeborg J Hochmair, Erwin S Hochmair: Single channel auditory stimulation system. Flehr Hohbach Test Albritton & Herbert, December 13, 1983: US04419995 (58 worldwide citation)

Chronic auditory stimulation is achieved by establishing an electric field at the base of the cochlea whereby full speech patterns are imparted to a patient. Penetration of the cochlea is not required thereby reducing the risks in installing the implanted electrodes. In a preferred embodiment the el ...

Ingeborg J Hochmair, Erwin S Hochmair: Method of fitting hearing prosthesis to a patient having impaired hearing. Flehr Hohbach Test Albritton & Herbert, March 25, 1986: US04577641 (41 worldwide citation)

Disclosed is a process of fitting a hearing prosthesis to a deaf or severely hearing impaired patient. The prosthesis is connected to the patient, and a signal is then applied to the prosthesis across an audioband. The frequency response of the prosthesis is adjusted so that the patient detects a de ...

Ingeborg J Hochmair, Erwin S Hochmair: Auditory stimulation using CW and pulsed signals. Flehr Hohbach Test Albritton & Herbert, June 10, 1986: US04593696 (41 worldwide citation)

An improvement in noise susceptibility is realized in auditory stimulation of the deaf by electrical signals. At least one analog electrical signal is applied to implanted electrodes in a patient, and at least one pulsatile signal is applied to implanted electrodes. The analog signal represents a sp ...

A cochlear implant system has a signal processor that fits in the ear canal of a user. The signal processor processes an acoustic signal present in the ear of the user to produce a representative radio signal. A power transmitter transmits an electrical power signal through the skin of the user. A c ...
