Patent number: 9845059Abstract: A method of creating in situ an acoustic enclosure in a space that is between body panels of a motor vehicle, wherein the space defines an empty volume, the method comprising placing into the space between body panels a molding tool that comprises a solid barrier that divides the space between body panels into an interior portion on an inside of the molding tool and an exterior portion that is external to an outside of the molding tool, where the outside of the molding tool is exposed to the space between body panels, and while the molding tool is in the space between the panels, introducing a fluid material into the exterior portion of the space between the body panels, wherein the fluid material is configured to cure into a solid shell.Type: GrantFiled: May 11, 2015Date of Patent: December 19, 2017Assignee: Bose CorporationInventors: Bradford Kyle Subat, Tobe Z. Barksdale, Charles E. Dunn, Jr., Lee Prager, Ben J. Feng

Patent number: 9802519Abstract: The technology can be embodied in a headrest that includes an enclosure that includes one or more acoustic transducers. The headrest includes a bar for mounting on a backrest of the seat, such that the mounted headrest is movable with respect to the backrest to different positions over an adjustable range. The bar includes one or more wires each of which is coupled to an electrical contact at one end, and an acoustic transducer at an opposite end, the one or more wires disposed within a hollow interior portion of the bar. The bar also includes an opening for permitting an electrical connection to be established between an electrical connector coupled to an external source, and the electrical contact coupled to the one or more wires. The connection is maintained over the adjustable range of the headrest by a mechanical bias on either the electrical connector or the electrical contact.Type: GrantFiled: March 16, 2016Date of Patent: October 31, 2017Assignee: Bose CorporationInventors: Bradford Kyle Subat, Charles E. Dunn, Jr., Charles Oswald, Kurt Mathew Heiden

Patent number: 7299076Abstract: A communication system for a vehicle is described. The communication system includes a microphone array having a plurality of microphones mounted within the vehicle for receiving acoustic signals and converting the acoustic signals to electrical signals. An antenna is mounted proximate to the microphone array. The antenna communicates a radio frequency signal to a wireless device. The communication system also includes a controller having a first input that is electrically coupled to at least one microphone in the microphone array and a second input that is electrically coupled to the antenna. The controller processes the electrical signals and transmits the processed electrical signals to the antenna.Type: GrantFiled: February 9, 2005Date of Patent: November 20, 2007Assignee: Bose CorporationInventors: Charles E. Dunn, Jr., Jeffery J. Faneuff

Patent number: 6828935Abstract: In a system according to the proposed technique (see figure), the signal received by each element of the array antenna would be subjected to downconversion, and spread-spectrum demodulation and correlation as necessary; this processing would be performed separately from, and simultaneously with, similar processing of signals received by the other antenna elements. For the GPS implementation, following downconversion to baseband, the signals would be digitized, and all subsequent processing would be digital. In the digital process, residual carriers would be removed and each signal would be correlated with a locally generated model pseudo random-noise code, all following normal GPS procedure. As part of this procedure, accumulated values would be added in software and the resulting signals would be phase-shifted in software by the amounts necessary to synthesize the desired antenna directional gain pattern of peaks and nulls.Type: GrantFiled: July 19, 2002Date of Patent: December 7, 2004Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Charles E.
