| 20080267418 | Method and apparatus for dynamically adjusting the spectral content of an audio signal - The present invention involves a method for dynamically adjusting the spectral content of an audio signal, which increases the harmonic content through the systematic introduction of amplitude asymmetry. The present invention also involves an apparatus for dynamically adjusting the spectral content of an audio signal which consists of a constant current source, an input buffer amplifier, an output buffer amplifier and a progressively biased system of bipolar junctions, which will produce a controlled asymmetry of the transfer characteristic. | 10-30-2008 |
| 20090046871 | METHOD AND APPARATUS FOR AUDIO PROCESSING - A method and apparatus for introducing a time-varying time delay randomly into the individual reproduction channels of a sound recording, two in the case of binaural presentation. This emulates the temporal aspect of microphone and/or listener motion. The present invention may be applied as a unidirectional process. No preparation of the source material is required. It can be applied to any multichannel audio signal set. It can process analog or digital signals. The process may be used with headphones, loudspeakers, hearing aids or similar assistive hearing devices. | 02-19-2009 |
| 20090071322 | Apparatus and method for broad spectrum radiation attenuation - A panel for use in assembling a radiation, microbial, acoustically, and ballistically shielded space within a building or other personal space. The panel is comprised of an ionizing radiation shielding material layer, a non-ionizing radiation shielding layer, an anti microbial treated layer, a bulletproof layer and an acoustical shielding layer. A method for using said panels to create a radiation, microbial, acoustic, and ballistic shielded space. | 03-19-2009 |
| 20090074102 | Method and apparatus for wired signal transmission - A method and apparatus for high quality signal transmission, which utilizes normal-mode current flow and produces an audio output signal with suppression of normal-mode voltage amplitude, comprising transmitting an audio input signal source though (1) a buffer amplifier; (2) a modulated current source; (3) a pair of wires; (4) a current transformer; and (5) a receiver amplifier for said current transformer. | 03-19-2009 |
| 20090292626 | SYSTEM AND METHOD FOR INTERACTIVE MAP, DATABASE, AND SOCIAL NETWORKING ENGINE - A system and method for selling or assigning locations to a purchaser. The location can be identified or delineated in several ways. Location identifiers may be used separately or in conjunction with each other. Sale of a particular location may be exclusive, partially-exclusive, or non-exclusive, depending on the particular embodiment of the system. A purchaser or potential purchaser may use digital, zoomable maps to identify locations of interest and possible purchase. The maps may be marked with locations already purchased, and this marking may be turned on and off by the purchaser when viewing the maps. In another embodiment, purchasers also have the option of expanding their participation to other linked aspects of the present invention, including but not limited to Web-based or other electronic access to interactive interfaces and/or social networking engines. Thus, for example, each assigned or purchased location, delineated by latitude and longitude, altitude, depth, and/or geographic or common name, may be identified on digital, zoomable Earth maps so that a user may view data input by other users regarding a particular location. Users also may register or subscribe to input data of their own regarding the location, and communicate electronically with other users of the invention. | 11-26-2009 |
| 20100246880 | METHOD AND APPARATUS FOR ENHANCED STIMULATION OF THE LIMBIC AUDITORY RESPONSE - A loudspeaker system for the optimization of sound production so as to achieve limbic and cortical arousal, comprising a resistance-controlled (or partially mass-controlled) woofer system, a mass-controlled (or partially resistance-controlled) midrange system, and a resistance-controlled tweeter system. This system may further comprise crossover networks of a particular configuration. By use of unsymmetrical networks of low order, it is possible to obtain a complete system which exhibits flat delay response. | 09-30-2010 |
| 20100284560 | AUDIO TRANSDUCER - An audio transducer for use in a loudspeaker system. The transducer includes a pair of flexible, curved diaphragms, with each diaphragm having a distal end and a proximal end. The curved diaphragms form hemi-cylindrical lobes being substantially tangent to one another at their proximal ends and are attached to energy absorbent dampers at their distal ends. The transducers can be employed in a line array as part of the loudspeaker system as well as some of the transducers facing forward while others rearward and, in doing so, their amplitudes and phases can be adjusted for fine tailoring the geometric coverage of acoustic energy radiating from the loudspeaker system. | 11-11-2010 |
| 20110096947 | SPHERICALLY HOUSED LOUDSPEAKER SYSTEM - A loudspeaker system for the reproduction of acoustic waves of music, sound and speech in a substantially circular horizontal plane. The loudspeaker system includes multiple spherical enclosures, each enclosure housing a pair of transducers, each pair of transducers producing acoustic waves of a predetermined frequency range. | 04-28-2011 |
| 20110153314 | METHOD FOR DYNAMICALLY ADJUSTING THE SPECTRAL CONTENT OF AN AUDIO SIGNAL - A method for dynamically adjusting the spectral content of an audio signal, which increases the harmonic content of said audio signal, said method comprising translating an encoded digital signal into data bands, creating a psychoacoustic model to identify sections of said data bands that are deficient in harmonic quality, analyzing the fundamental frequency and amplitude of said harmonically deficient data bands, creating additional higher order harmonics for said harmonically deficient data bands, adding said higher order harmonics back to said encoded digital signal to form a newly enhanced signal, inverse filtering said newly enhanced signal, and converting said inverse filtered signal to an analog waveform for consumption by the listener. | 06-23-2011 |
