Patent number: 7987977Abstract: A hearing aid is enclosed in a gas-impermeable or substantially gas-impermeable package to prevent inadvertent activation of the hearing aid during transport. The package may include a housing having a groove that substantially conforms to at least a portion of the shape of the hearing aid to snugly hold the hearing aid. The groove may be substantially open adjacent a switch on the hearing aid. A securing member, such as a strap, may be used to immobilize the switch relative to the housing.Type: GrantFiled: June 30, 2004Date of Patent: August 2, 2011Assignee: Sarnoff CorporationInventors: Marvin A. Leedom, John G. Aceti, Walter P. Sjursen, Derek D. Mahoney, John M. Margicin, Michael H. Tardugno, Robert R. Demers, John E. Oltman, Robert C. Maxwell, Frederick J. Fritz

Patent number: 7403629Abstract: The present invention relates to a modular hearing aid having a base unit and a detachable earmold. A battery, an earmold tip and a receiver can be integrated with the earmold. The earmold can also include a removably attached module. The module can have a shell, electronics, a receiver or a microphone. A hearing aid also includes a flexible hearing aid tip having a vibration isolator portion and a mushroom shaped tip portion. The vibration isolator portion mechanically decouples a receiver from a hearing aid base unit while the mushroom shaped tip portion provides an acoustic seal in the ear canal of a user. The internal components of a hearing aid can be potted to attenuate vibrations created by the receiver during operation.Type: GrantFiled: March 13, 2000Date of Patent: July 22, 2008Assignee: Sarnoff CorporationInventors: John G.

Publication number: 20070121967Abstract: A disposable-type hearing aid uses a relatively large single diaphragm or a large single diaphragm subdivided into a plurality of smaller active diaphragm areas obtained using a grate-like back support plate with ridges which contact and divide the diaphragm into the several smaller active diaphragm areas. The diaphragm and a backplate are enclosed in a metal housing and are disposed proximal and parallel to a shell-like hearing aid enclosure having sound inlets. The metal housing is closed at an end opposite the sound inlets by a printed circuit board (PCB) forming an acoustical seal for a back volume of the microphone. The PCB also carries substantially all the electronic components for the hearing aid thereon. The PCB has a ground plane in contact with the housing whereby the PCB also acts as an EMI shield. An electrical connection is formed in various ways between the back support plate and the PCB during assembly of the metal housing and components with the PCB.Type: ApplicationFiled: August 3, 2006Publication date: May 31, 2007Inventors: Walter Sjursen, Marvin Leedom, Derek Mahoney, John Margicin, Frederick Fritz, John Aceti, David Preves, Ponnusamy Palanisamy

Patent number: 5881159Abstract: A hearing aid includes an electronic assembly mounted in a cylindrical shell with the shell being mounted in an opening in a ear mold. The electronics assembly includes a printed circuit strip having thereon a speaker, a microphone and electronic components forming a signal processing circuit for amplifying the sound. The ear mold is of a soft, durable and compliant material so that it will fit tightly in the ear of a user. The hearing aid is of optimum design having a minimum number of components and is easy to assemble on an automatic basis. This provides a hearing aid which is relatively inexpensive so as to be disposable.Type: GrantFiled: March 12, 1997Date of Patent: March 9, 1999Assignee: Sarnoff CorporationInventors: John G.

Patent number: 4341472Abstract: A technique for positioning a body having a tapered profile when viewed along a first axis comprises exposing the body to a first beam of light oriented along the first axis in a manner such that the tapered profile is projected as a first image onto a first linear array of photodectors disposed along a direction orthogonal to both the first axis and the direction of the taper. The body is exposed to a second beam of light oriented along a second axis orthogonal to the first axis in a manner such that a second profile of the body is projected as a second image onto a second linear array of photodetectors disposed along a direction parallel to the first axis. The body is then moved along the first and the second axes until the first and the second images strike predetermined locations along the first and second photodetector arrays.Type: GrantFiled: September 15, 1980Date of Patent: July 27, 1982Assignee: RCA CorporationInventors: Istvan Gorog, Marvin A.

Patent number: 4330735Abstract: A beam guide assembly for a flat panel display device includes a plurality of meshes arranged in a spaced parallel relationship. Insulative supports permanently retain the meshes in the spaced relationship. The supports preferably comprises glass rods or beads spaced along the length of the assembly with portions of the meshes embedded therein. The beads are transversely displaced to allow beads of adjacent assemblies to be interleaved in a common aligned column. The beam guide assemblies can readily be fabricated and assembled using automatic and mass production techniques.Type: GrantFiled: February 29, 1980Date of Patent: May 18, 1982Assignee: RCA CorporationInventor: Marvin A.
