20070039776 - Seabed seismic source apparatus: A seabed seismic source apparatus includes a control module adapted for deployment at a seabed. The control module has a receiver for receiving a remote signal and a firing controller for generating a firing signal in response to the remote signal. The seabed seismic source apparatus further includes at least... Agent: Schlumberger Oilfield Services

20070039777 - Speaker enclosure for a wall mounted speaker system: A speaker enclosure kit for retro-installing a speaker enclosure for a wall mounted speaker is provided along with a process of retro-installing a speaker enclosure for a wall mounted speaker. The speaker enclosure kit includes a speaker surround member having a foam polymer, such as a foam urethane, attached to... Agent: William M. Hobby, Iii

20070034443 - Loudspeaker diaphragm: Wholly aromatic polyamide fibers cut to a length of 0.5 to 5 mm are dispersedly contained in an injection-moldable thermoplastic resin, and the resin is molded by ultrahigh-speed thin-wall injection molding so as to produce a loudspeaker diaphragm in which the wholly aromatic polyamide fibers are dispersed in a direction... Agent: C. Irvin Mcclelland Oblon, Spivak, Mcclelland, Maier & Neustadt, P.C.

20070034444 - Reflecting plate type silencer pipe: A reflecting plate type silencer pipe including a reflecting plate is provided for reducing a dominant frequency noise passing through a pipeline. Sound waves propagated in the pipeline as a one-dimensional plane wave are divided into two, that is, sound waves advancing straight along the pipeline and sound waves caused... Agent: Christensen, O'connor, Johnson, Kindness, PLLC

20070034445 - Acoustic panel of the air sheet type: The invention relates to an acoustic panel presenting at least two plates together with at least one spacer for keeping said two plates spaced apart so as to form at least one sheet of air. In the panel, said spacer is constituted by a woven or knitted element, e.g. of... Agent: Clark & Brody

20070034447 - Acoustic liner with bypass cooling: An acoustic liner 20 includes a remote panel 26, a proximate panel 28 transversely spaced from the remote panel and a resonator chamber 34b residing between the panels. Perforations 38 penetrate the proximate panel in registration with the resonator chamber 34b. A neck 56 with an inlet 58 recessed from... Agent: Pratt & Whitney

20070034446 - Architecture for an acoustic liner: An acoustic liner 20 includes a remote panel 26, a perforated proximate panel 22 transversely spaced from the remote panel and one or more partitions 32 spanning across the space between the panels. At least one baffle 44 cooperates with the partitions to define a resonator chamber 34b and an... Agent: Pratt & Whitney

20070034448 - Hybrid amplitude-phase grating diffusers: A room acoustic diffuser exploits interference, by reflecting waves out-of-phase with the specular energy, making it possible to diminish specular energy. This is achieved by using a diffuser based on a ternary sequence, which nominally has reflection coefficients of 0, −1 and +1. A method for obtaining the design sequence... Agent: H. Jay Spiegel - H. Jay Spiegel & Associates

20070023228 - Multifunction speaker cabinet: A multifunction speaker cabinet has a USB input on one side of the speaker cabinet while the USB input is connected with a plurality of USB output exposed on another side of the speaker cabinet so that users can insert several flash into the USB output for connection with the... Agent: Lowe Hauptman Berner, LLP

20070023229 - Diaphragm for micro-electroacoustic device: A diaphragm for a micro-electroacoustic transducer, includes a first layer including an exposed region and a covered region, and a second layer. The second layer overlaps the covered region of the first layer to thereby increase the rigidity of the diaphragm. The covered region is surrounded by the exposed region.... Agent: PCe Industry, Inc. Att. Cheng-ju Chiang Jeffrey T. Knapp

20070023230 - Variable resonator: A communicating pipe is disposed on an outer periphery of an air intake pipe, and a conduit is formed so as to be parallel to an air intake passage. A plurality of first communicating apertures are disposed through the air intake pipe so as to be arranged in a single... Agent: Sughrue Mion, PLLC
