Publication number: 20150127258Abstract: A method and system for assisting a traveler. The method initiates a travel segment and interfaces with providers of data regarding geolocation, points of interest, or traffic. During execution of the method, the system monitors geolocation data. The system can predict a route of travel, basing that prediction on past geolocation data or directions from a geolocation provider. Also during execution of the method, the system can identify data of interest to a user, based on input initiated by the user. Further, the system can solicit input from the traveler, or it can perform tasks based on predefined criteria, such as locating and identifying points of interest between two geographic locations. During operation, system can provide information to the traveler relating to data of interest. The system includes a client unit and a server unit, the client unit being mounted in an automotive vehicle or in a communications device.Type: ApplicationFiled: November 7, 2013Publication date: May 7, 2015Applicant: SOUNDHOUND, INC.Inventors: BERNARD MONT-REYNAUD, KEYVAN MOHAJER, LARRY MARCUS

Patent number: 8300871Abstract: An earphone device capable of achieving sound bandwidths beyond the 150-7000 Hz wideband range, and configured for supra-concha or supra-aural placement. The earphone comprises at least two frequency range receivers positioned within a housing. In at least one embodiment, the earphone is capable of achieving a super-wideband range by physically combining a low frequency range receiver and a high frequency range receiver in a space-efficient and acoustically advantageous manner.Type: GrantFiled: November 5, 2007Date of Patent: October 30, 2012Assignee: MWM Acoustics, LLCInventors: Christopher T. Welsh, Larry A. Marcus, John C. Baumhauer, Jr.

Patent number: 7751575Abstract: The microphone system for communication devices that comprises an electric circuit comprising two microphone elements connected to a signal flow processor. This processor uses a digital signal processor or comparable analog circuitry to provide a particular electrical time delay (?) to one of the microphone elements (nearest the ear or loudspeaker) and a compatible amplitude gain (Gm1) to the other microphone element (nearest the user's mouth) in order to substantially reduce the external acoustic coupling and echo of communication devices in the receive and doubletalk state. Further, this processing system allows the microphone system to reduce the pickup of ambient noise in the send and idle state, while still being sensitive to the user's speech.Type: GrantFiled: September 25, 2003Date of Patent: July 6, 2010Inventors: John C. Baumhauer, Jr., Larry A. Marcus, Christopher T. Welsh, Alan D. Michel, Jeffrey Phillip McAteer

Publication number: 20070126164Abstract: A microphone isolation system. The system includes an isolation member, a support member, and at least two compliant members. The at least two compliant members mechanically support the isolation member and isolate the isolation member from vibrations. The at least two compliant members can also isolate the support member from any vibratory excitation source coupled to and/or supported by the isolation member.Type: ApplicationFiled: February 6, 2007Publication date: June 7, 2007Applicant: POLYCOM, INC.Inventors: John Baumhauer, Robert Spaller, Thao Hovanky, Larry Marcus, Peter Chu, Denton Simpson

Patent number: 5586183Abstract: A compact telephone handset, when not in use, is shorter in length than the distance between a user's ear and mouth and has an extendable boom for lengthening the telephone to a length equal to the distance between the user's ear and mouth. The handset has a receiver device and a microphone device with one of the devices being located on the main body of the handset and the other device being located on a slidable boom which is extendable and retractable relative to the main body.Type: GrantFiled: April 10, 1996Date of Patent: December 17, 1996Assignee: Lucent Technologies Inc.Inventors: Larry A.

Patent number: 5450372Abstract: In accordance with the invention, a new type of microphone utilizes a magnetoresistive sensing element. Specifically, acoustical energy causes vibrations between a magnetoresistive element and a magnet, producing a variation in the resistance which can be used to convert an acoustical signal into a corresponding electrical signal.Type: GrantFiled: March 30, 1994Date of Patent: September 12, 1995Assignee: AT&T Corp.Inventors: Sungho Jin, Larry A. Marcus, Mark T. McCormack

Patent number: 5291541Abstract: Coupling apparatus for a telephone handset comprises a handset-coupling cradle having a dome at one end thereof for locating the earpiece (receiver) of the handset, and sound ports at the other end of the cradle in the region where the mouthpiece (microphone) of the handset resides. The handset-coupling cradle is shaped to accommodate a variety of different handset styles. An inductive sensor is mounted within the dome and it responds to electromagnetic fields generated by the handset receiver. Such a sensor eliminates the need to closely couple the receiver to the apparatus. A low acoustic impedance loudspeaker is mounted beneath the sound ports for acoustically coupling signals to the handset's microphone. Such a loudspeaker eliminates the need to closely couple the microphone to the apparatus.Type: GrantFiled: December 21, 1992Date of Patent: March 1, 1994Assignee: AT&T Bell LaboratoriesInventors: Clinton D. Gibler, Larry A. Marcus, Frederick A. Rosebrock, Perry K. White
