Publication number: 20090253951Abstract: A floating mass transducer for assisting hearing in a person is provided. Inertial vibration in the floating mass transducer (100) produces vibrations in the inner ear. In an exemplary embodiment, the floating mass transducer comprises a magnet assembly (12) and a coil (14) secured inside a housing (10) which is attached to bone within the middle ear. The coil is more rigidly secured to the housing than the magnet. The magnet assembly and coil are configured such that conducting alternating electrical current through the coil results in vibration of the magnet assembly and coil relative to one another. The vibration is caused by the interaction of the magnetic fields of the magnet assembly and coil. Because the coil is more rigidly secured to the housing than the magnet assembly, the vibrations of the coil cause the housing to vibrate. The floating mass transducer may generate vibrations in the inner ear by being attached to the skull or through a mouthpiece.Type: ApplicationFiled: June 18, 2009Publication date: October 8, 2009Applicant: VIBRANT MED-EL HEARING TECHNOLOGY GMBHInventors: Geoffrey R. Ball, Kenneth J. Dormer, Jack Van Doren Hough, Gordon L. Richard, Christopher A. Julian

Patent number: 6783687Abstract: A method and apparatus for separating ions from a stream of fluid containing ions. A magnetic field and an electrostatic field are established across a processing zone through which the fluid stream flows so that the flow vector of the fluid stream, the flux lines of the magnetic field, and the vector of the electrostatic field are mutually orthogonal. The resulting high and low ion effluents may be further processed. No thermal input is required. No vacuum, reverse osmosis or reduced pressure distillation is involved. Large volumes of fluid may be processed at relatively low cost. The disclosed method and apparatus is suitable for desalinating seawater, or for removing arsenic or other contaminants from ground water, to produce potable water. Additionally, the invention permits the recovery of valuable constituents from ground or sea water; precious metals may be recovered from sea water and gypsum may be collected from ground water.Type: GrantFiled: October 11, 2002Date of Patent: August 31, 2004Inventor: Gordon L. Richard

Patent number: 4617536Abstract: An apparatus and a method modulate a carrier signal so that the resultant modulated signal varies between a value substantially equal to the quiescent level of the carrier signal and peak values up to several hundred percent of the quiescent level of the carrier signal. The apparatus includes an electrical circuit for adjusting the modulating signal so that it is clamped at a reference value to prevent overmodulation. The clamped signal controls a variable resistance mechanism which forms a part of the gain determining portion of a modulator circuit including an amplifier. The amplifier modulates the carrier signal in accordance with the gain determined by the variable resistance. The variable resistance is controlled by the clamped signal so that it causes the gain of the amplifier circuit to vary between approximately one and a value greater than one.Type: GrantFiled: June 15, 1984Date of Patent: October 14, 1986Assignee: Baptist Medical Center of Oklahoma, Inc.Inventor: Gordon L.

Patent number: 4612915Abstract: A direct bone conduction hearing aid device is disclosed and includes a sound processor for receiving sound and generating an amplified electromagnetic signal in response thereto. This signal is transmitted to a subcutaneously implanted vibration generating means which is secured to a skull bone of the user and which includes magnetic means. An analog signal causes the magnet to vibrate and these vibrations are transmitted to the skull bone and thence to the cochlea to create the perception of sound.Type: GrantFiled: May 23, 1985Date of Patent: September 23, 1986Assignee: Xomed, Inc.Inventors: Jack V. D. Hough, Gordon L. Richard, Kenneth E. Barton, Jr., Paul DiCarlo, Robert Y. Chow

Patent number: 4352960Abstract: Disclosed is a transcutaneous coupling apparatus comprising a first member subcutaneously positioned in a user of the invention and also comprising a second member positioned supercutaneously, or outside the skin of the user. Rare-earth magnets are associated with the first and second members to magnetically secure the second member with the first member without significantly adversely affecting the user's skin intervening between the first and second members.Type: GrantFiled: September 30, 1980Date of Patent: October 5, 1982Assignee: Baptist Medical Center of Oklahoma, Inc.Inventors: Kenneth J. Dormer, Gordon L. Richard
