20090026006 | Foaming liquid material and use thereof for reducing noise in mounted tires - The present invention is directed to a method of reducing noise transmission in a pneumatic tire and wheel assembly comprising an inflation cavity, the method comprising the step of adding to the inflation cavity from about 0.1 to about 1 volume percent, based on the volume of the inflation cavity, of a repeatably foamable liquid. | 01-29-2009 |
20090050401 | Composite Sound Barrier Panel - A composite sound barrier panel includes a concrete substrate provided for strength and a noise attenuation layer bonded thereto. The noise attenuation layer in one embodiment is a concrete mixture of a fiber composite material and cement. In another embodiment, recycled wood chips are added to the mixture. A plurality of identical panels are pre-cast in a mold for use in forming a noise abatement wall, particularly between a residential neighborhood and a highway. | 02-26-2009 |
20090065290 | INTERFLOOR NOISE REDUCTION PANEL WITH AIR PURIFYING AND STERILIZING FUNCTIONS FOR BUILDING - An interfloor noise reduction panel with an air purifying function for buildings is capable of reducing impact due to the dropping of a weight and electromotive forces of machinery as well as noise and vibration transmitted through the floor of the building through the structure in which a plurality of springs, a sound-absorbing material, an ion mortar layer are disposed in a base panel such that noise generated by pressure applied to the panel above is absorbed and thus maximally extinguished. | 03-12-2009 |
20090107758 | METHOD AND APPARATUS FOR DETECTING EXPLOSIVES - A method and apparatus is provided for detecting explosives by thermal imaging. The explosive material is subjected to a high energy wave which can be either a sound wave or an electromagnetic wave which will initiate a chemical reaction in the explosive material which chemical reaction will produce heat. The heat is then sensed by a thermal imaging device which will provide a signal to a computing device which will alert a user of the apparatus to the possibility of an explosive device being present. | 04-30-2009 |
20090127020 | ACOUSTICALLY TRANSMISSIVE BLANKET SYSTEM - A blanket system, which can include a blanket, quilt, or similar bed-covering can include one or more localized sound-emitting areas, one or more separately-located sound-processing devices, and one or more acoustically transmissive communication channels coupled between the sound-processing devices and the sound-emitting areas. A control can be provided to adjust the sound characteristics provided at the sound-emitting areas. The system can be used to mask unwanted sounds. | 05-21-2009 |
20090321178 | METHOD AND SYSTEM FOR DAMPED ACOUSTIC PANELS - A method and system for an acoustic panel system are provided. The system includes a plurality of acoustic panel segments aligned circumferentially about an inner diameter of a fan containment case wherein each segment includes a radially inner surface defining a portion of a fluid duct, a radially outer surface defining a gap between the fan containment case and the acoustic panel segment, and an aft end lip configured to be inserted into a mating groove in the fan containment case. The system also includes at least one damping bumper coupled to the radially outer surface wherein the bumper extends from the radially outer surface to the fan containment case and comprises an energy absorbing elastomeric material configured to facilitate dissipating a forced response of a vibratory stimulus. | 12-31-2009 |
20100032232 | SPEAKER DEVICE AND DISPLAY APPARATUS HAVING THE SAME - A speaker device of a video display apparatus which realizes a high quality sound by improving a bass property even in the case that an enclosure unit has a smaller internal volume than that a speaker unit should basically have is provided. The speaker device includes at least one speaker unit, an enclosure unit which contains and supports the speaker unit and has an opening formed on a side surface thereof, and a cover which closes and seals the opening of the enclosure unit and is movable by an air movement inside the enclosure unit. The cover is formed of a material which is not permeable to air, and this material may be at least one of resin, textile, vinyl and paper. The cover may be formed of a foam rubber of an elastomeric system. | 02-11-2010 |
20100193281 | Sound Projection Device Attachable to a User When Not in Use - A megaphone comprises a rigid but bendable material with a tapered shape. When the material is folded, the produced megaphone has a small opening at one end and a larger opening at the other end. The megaphone has edges that form an opening along the side such that when pressure is applied to the edges the opening expands allowing the megaphone to be positioned on a person's arm or leg. Once positioned on the arm of leg the rigidity of the material causes the megaphone return to its original cone shape. The megaphone can enclose around a user's arm or leg for storage purposes during an event. Information can be displayed on the surface of the megaphone. The megaphone of the present invention can be folded and unfolded. | 08-05-2010 |
20140069735 | VENTILATION DENOISING DEVICE AND VENTILATION DENOISING SYSTEM - A ventilation denoising device that includes at least one ventilation module disposed with at least two air ducts inside, the air ducts are communicated end-to-end to form a circuitous air duct. The ventilation module is provided with a first ventilation opening communicated with one end of the air duct, and a second ventilation opening communicated with the other end of the air duct. Also disclosed is a ventilation denoising system equipped with the above mentioned ventilation denoising device. The ventilation denoising device can be installed outside equipments, such as a machine cabinet, as ventilation means thereof, and also reduce the noise generated during the equipment operation. | 03-13-2014 |
20140345967 | RETROREFLECTIVE HEATER - An apparatus for directing thermal infrared energy toward or away from a target is disclosed. The apparatus comprises a covering having a plurality of retroreflective elements. The plurality of retroreflective elements are configured to retroreflect electromagnetic beams primarily at thermal infrared wavelengths, receive the electromagnetic beams from the target along beam reception paths, and reflect the electromagnetic beams back toward the target along beam reflection paths. The beam reflection paths have substantially the same elevation angle and/or azimuth angle as their respective beam reception paths. | 11-27-2014 |
20140360805 | AUDIO EQUIPPED FAN - An audio equipped fan is disclosed as having a housing, and a grille connected to the housing, and defining first openings through which air may flow while the fan is rotated, and second openings through which sound may travel. The fan also has an annular lighting array configured to selectively provide lighting in a high power or a low power configuration, and speakers connected to the grille and aligned on the interior side of the grille with the second openings of the grille so that sound may travel through the grille. Related methods are also disclosed. | 12-11-2014 |
