Patent number: 5178957Abstract: A composite article is prepared as a polymeric support having a coating of noble metal deposited on at least one surface thereof, the coating exhibiting suitable peel force for high performance applications such as the preparation of an electrode, such as a biocompatible, flexible, thin-film microelectrode where in the composite article can be prepared by pretreating at least one surface of the support by sputter etching, followed by sputter-depositing a noble metal on the pretreated surface in order to form the coating of noble metal.Type: GrantFiled: July 2, 1991Date of Patent: January 12, 1993Assignee: Minnesota Mining and Manufacturing CompanyInventors: Vasant V.

Patent number: 4969534Abstract: The casing of a hearing aid can be acoustically dampened and its receiver is less likely to amplify noise stemming from vibrations of the casing when the casing is lined with a viscoelastic material. The viscoelastic lining can be applied by laying a viscoelastic layer across the rim of the casing and drawing a vacuum at the sound-communicating orifice of the casing until the viscoelastic is drawn tightly against the interior of the casing. A preferred viscoelastic layer has at one surface a substance such as fibers or beads that will form temporary bridges to permit an air to be evacuated between the viscoelastic layer and a casing to which it is applied. When the deposited viscoelastic is tacky at room temperature, the components of the hearing aid can be positioned simply by pressing them into the viscoelastic material, thus making the assembly easier than prior methods of assembling tiny hearing aids.Type: GrantFiled: August 8, 1988Date of Patent: November 13, 1990Assignee: Minnesota Mining and Manufacturing CompanyInventors: Vasant V. Kolpe, Davis W. Chamberlin, Robert J. Oliveira

Patent number: 4880076Abstract: Detachably secured to the ear piece of a hearing aid is a user-disposable sleeve comprising soft polymeric retarded recovery foam that can be compressed to be freely insertable into a person's ear canal and then allowed to recover to become wedged in the canal. The sleeve preferably includes a flexible, elongated plastic duct over which the foam fits, and the duct is formed with a screw thread of a rigid plastic which mates with a screw thread on the ear piece for easy attachment and removal. The external surface of the foam preferably is substantially cylindrical and can be formed with flutes to provide venting of the user's ear.Type: GrantFiled: December 5, 1986Date of Patent: November 14, 1989Assignee: Minnesota Mining and Manufacturing CompanyInventors: Carl S. Ahlberg, Davis W. Chamberlin, Jerold W. Bushong, Robert J. Oliveira, Vasant V. Kolpe
