Patent number: 7198133Abstract: A one-piece, transparent flexible ear coupler for use with hearing evaluation is disclosed. It includes an annular side wall and a bottom wall forming an acoustic chamber. A flexible adhesive-backed flange is disposed on the periphery of the ear coupler. The flange attaches to the subject's head, firmly holding the ear coupler in place over the ear. The annular side wall has a port for the placement of a transducer assembly, and also has ribs to help lock the transducer assembly in place. The transducer assembly can be placed in an up or down position, and can be switched between positions while the coupler is attached to the subject's head. The ear coupler advantageously conforms to the subject's head, thereby minimizing the likelihood that the ear coupler will become detached during testing. The coupler can be inexpensively manufactured, since its one-piece design allows the use of relatively low-cost processes such as injection molding and thermoforming.Type: GrantFiled: June 3, 2004Date of Patent: April 3, 2007Inventors: Jessica Ash Warring, Alfred Christian Walton

Patent number: 6938338Abstract: Microelectronic contacts, such as flexible, tab-like, cantilever contacts, are provided with asperities disposed in a regular pattern. Each asperity has a sharp feature at its tip remote from the surface of the contact. As mating microelectronic elements are engaged with the contacts, a wiping action causes the sharp features of the asperities to scrape the mating element, so as to provide effective electrical interconnection and, optionally, effective metallurgical bonding between the contact and the mating element upon activation of a bonding material.Type: GrantFiled: April 17, 2003Date of Patent: September 6, 2005Assignee: Tessera, Inc.Inventors: Joseph Fjelstad, John W. Smith, Thomas H. DiStefano, James Zaccardi, A. Christian Walton

Patent number: 6475163Abstract: An apparatus and method for evaluation of hearing loss is disclosed. The apparatus and method use evoked Auditory Brainstem Responses (ABR) to determine if the subject is able to hear iteratively administered click stimuli. The present invention evaluates the sufficiency of the patient connections, namely earphones and electrodes, to the evaluation device. More particularly, the present invention determines if the earphones are detached or deformed, if the electrodes have been reversed, or if the electrodes have become detached.Type: GrantFiled: January 7, 2000Date of Patent: November 5, 2002Assignee: Natus Medical, IncInventors: Matthijs P.

Patent number: 6386314Abstract: An earphone assembly is disclosed that includes an annular baffle having an outer surface and an inner surface as well as an interior wall and an exterior wall. The interior wall defines a central chamber. A transparent, flexible lid is attached to the baffle along the outer surface, completely covering the central chamber and forming an acoustic seal with the baffle. The lid has an inner face and an outer face. The flexibility of the earphone is improved by creating hinges in the lid and by providing cuts, or other discontinuities, in the baffle. For example, a radial cut may be disposed in the annular baffle. Further, a circumferential cut may also (or alternatively) be disposed in the baffle, extending from the inner surface and disposed between the exterior wall and the interior wall. At least one hinge may be disposed on the flexible lid. To improve the attachment of the earphone to the patient's head, tabs are mounted to the exterior wall.Type: GrantFiled: September 14, 1999Date of Patent: May 14, 2002Assignee: Natus Medical, Inc.Inventors: Neil J. Sheehan, Christian Walton, David Sheraton, Toshibumi Wakayama, William New, Jr.

Patent number: 5812378Abstract: A connector for microelectronic includes a sheet-like body having a plurality of holes, desirably arranged in a regular grid pattern. Each hole is provided with a resilient laminar contact such as a ring of a sheet metal having a plurality of projections extending inwardly over the hole of a first major surface of the body. Terminals on a second surface of the connector body are electrically connected to the contacts. The connector can be attached to a substrate such a multi-layer circuit panel so that the terminals on the connector are electrically connected to the leads within the substrate. Microelectronic elements having bump leads thereon may be engaged with the connector and hence connected to the substrate, by advancing the bump leads into the holes of the connector to engage the bump leads with the contacts. The assembly can be tested, and if found acceptable, the bump leads can be permanently bonded to the contacts.Type: GrantFiled: August 4, 1995Date of Patent: September 22, 1998Assignee: Tessera, Inc.Inventors: Joseph Fjelstad, John W.
