Patent number: 8077896Abstract: Outputs of a laser and an inclinometer are used to figure adjustments to a sound producing device's position, where both the laser beam of the laser and an output from the inclinometer characterize a general direction of sound produced by the sound producing device. The laser beam can be one or more colors or patterns each characterizing the general direction of sound produced by the sound producing device. A stadium can have many speaker housings each including a speaker, the laser, and the inclinometer. Each speaker housing is mounted on, and remotely adjustable with respect to, an structural member as to general direction of sound emitted from the speaker housing into the area for stadium seating. The inclinometer's output can be rendered by a monitor seen by an audio engineer who also uses the laser beam's direction to make adjustments to the position of the speaker housing relative to its structural member.Type: GrantFiled: December 11, 2007Date of Patent: December 13, 2011Assignee: Sound Services, LLCInventors: Marcus E. Ross, Scott A. Sugden

Publication number: 20110300468Abstract: A housing contains a fuel cell, a lithium ion secondary cell, a wiring board on which a control circuit and the like are mounted, a light-emitting diode and the like. The bottom surface of the housing is covered with a bottom plate. A plurality of air-intake holes are formed in the bottom plate to supply air to the fuel cell. Two USB ports and are provided in the periphery of the housing. A plurality of air-discharge holes are formed in the upper portion of the periphery of the housing. Gas in the housing is discharged to the outside through the air-discharge holes. Furthermore, light from an LED provided in the housing works as an illumination for the fuel cartridge, which can facilitate checking of the fluid level of the fuel cartridge, thus, checking of the amount of remaining fuel.Type: ApplicationFiled: February 4, 2010Publication date: December 8, 2011Applicant: SONY CORPORATIONInventors: Hiroshi Takabayashi, Akihisa Inatani, Yoshiaki Kumagai, Arinobu Ueda

Patent number: 8073176Abstract: The present invention introduces a speakerbar which mounts above or below a flat screen TV and reproduces the surround sound experience normally associated with speakers placed in five to seven separate locations around the room. This particular invention effectively increases the perceived stereo separation of the left and right front speakers, and creates the perception of two and even four surround speakers typically placed in the rear of the listening area. In addition, it introduces new technology to achieve multichannel bass extension beyond the normal limitations due to the minimal internal volume of a multichannel speakerbar.Type: GrantFiled: January 5, 2009Date of Patent: December 6, 2011Inventor: Bernard Bottum

Publication number: 20110274304Abstract: A method for adapting a small stereo speaker for mounting in a hole designed for a larger speaker (the hole being in a mounting wall). A pair of adapters are provided. These are plates which include an inner perimeter and an outer perimeter. When the two plates are placed together (like book ends) the inner perimeters of the two plates define an opening appropriately sized for the small speaker. The outer perimeters of the two plates include mounting holes and/or slots which are sized and positioned to align with the mounting holes typically used for the larger speaker.Type: ApplicationFiled: May 7, 2010Publication date: November 10, 2011Inventors: Robert Scott Wafer, David Dean Schaefer, Colin Becker Ehrhardt

Patent number: 8050420Abstract: An integrated seat speaker includes a cushion, a seat frame defining a first internal air volume, and a speaker enclosure defining a second internal air volume. The second internal air volume is acoustically coupled to the first internal air volume through an air passageway, thus producing a continuous acoustical air volume. An acoustic sealing member is disposed between the enclosure and the frame. The frame includes a closure feature at one end for isolating a portion of the first internal air volume. The cushion includes an outer surface, and the speaker enclosure is enclosed within the seat cushion and at least partially concealed by the outer surface. A method optimizes the acoustical performance of a speaker assembly by acoustically coupling an internal air volume defined by a speaker enclosure to another internal air volume defined by a seat frame to create a continuous acoustical air volume.Type: GrantFiled: January 31, 2008Date of Patent: November 1, 2011Assignee: GM Global Technology Operations LLCInventors: Richard A.
