摘要： A directional microphone intended for use in a computer visual display monitor, and methods for construction of same. The integral directional microphone assembly comprises a cardioid electret microphone capsule retained therein by acoustically transparent foam. The microphone housing is mounted internally within a display monitor housing facing the user and adjacent to the top surface of the monitor housing. The microphone housing comprises a frontal opening and a plurality of nonfrontally facing openings which together maximally preserve sound pressure gradient applied to the microphone capsule, resulting in a hypercardioid spatial response.

摘要： A high quality stereophonic sound enclosure system high resolution intended for computer visual display monitors employing cathode ray tubes (CRTs) having a vertical aperture grill, and methods for construction of same. The aperture grill has a natural frequency centered within the musical scale. The stereo speaker system comprises a ported speaker enclosure within which are mounted two conventional cone speaker assemblies. A stereo audio amplifier and control unit for controlling the audio signals delivered to the speakers is mounted within the speaker enclosure. The speaker enclosure is internally mounted within the monitor with a minimum number of attachment members incorporating vibration isolation material to remove vibration components near the natural frequency of the aperture grill. The speaker enclosure is internally reinforced to reduce structural deformations which contribute to airborne transmitted vibration within the monitor housing when the speaker system is operating.

摘要： A communication system (e.g., a speakerphone) includes an array of microphones, a speaker, memory and a processor. The processor may be configured to perform acoustic echo cancellation, to track multiple talkers with highly directed beams, to design beams with nulls pointed at noise sources, to generate a 3D model of the physical environment, to compensate for the proximity effect, and to perform dereverberation of a talker's voice signal. The processor may also be configured to use a standard codec in non-standard ways. The processor may perform a virtual broadside scan on the microphone array, analyze the resulting amplitude envelope for acoustic source angles, examine each of the source angles with a directed beam, combine the beam outputs that show the characteristics of intelligence or speech.

摘要： A processor operates on samples of a digital output signal to determine samples of a digital correction signal. The output signal samples are directed to an output channel for transmission from a speaker. The digital correction signal samples are supplied to a first digital-to-analog converter for conversion into an analog correction signal. The subtraction circuit generates a difference between a first analog signal provided by a microphone and the analog correction signal. The analog correction signal is an estimate of a contribution to the first analog signal due to a direct path transmission between the speaker and the microphone. The processor also receives a digital input signal derived from the difference signal, and, performs acoustic echo cancellation on the digital input signal to obtain a resultant signal. The acoustic echo cancellation is configured to remove contributions to the digital input signal due to reflected path transmissions.

摘要： Embodiments of systems and methods which provide highly specific control over the execution of general-purpose code block are disclosed. These embodiments may allow the exact circumstances under which a given code block is allowed to execute to be determined with specificity. Such a control mechanism may be coupled with embodiments of a data hiding system and method, based for example, on an ordered execution of a set of code segments implemented via recursive execution. When embodiments of these systems and methods are utilized together an unencumbered generality as well as a level of protection against attack that surpasses many other security systems may be obtained.
