20150179181 | ADAPTING AUDIO BASED UPON DETECTED ENVIRONMENTAL ACCOUSTICS - Technologies pertaining to improving an auditory experience of a listener are described. Audio is modified based upon noise generated by noise sources in an environment. A microphone generates a signal that is representative of noise in the environment, and the signal is processed to identify peak frequencies therein. When a key frequency of the audio is proximate to a peak frequency in the noise, the audio is modified to improve the listener's perception of the audio. | 06-25-2015 |
20150195644 | STRUCTURAL ELEMENT FOR SOUND FIELD ESTIMATION AND PRODUCTION - A structural or aesthetic construction element, such as a wall section, is described herein, wherein the construction element has embedded therein an array of microphones, an array of speakers, and processing electronics that drives the array of microphones and the array of speakers. Audio captured by the microphones can be used to estimate a sound field corresponding to the construction element. Speakers in the array of speakers are configured to directionally output audio, such that a desired sound field is produced or reproduced. | 07-09-2015 |
20150208166 | ENHANCED SPATIAL IMPRESSION FOR HOME AUDIO - Technologies pertaining to provision of customized audio to each listener in a plurality of listeners are described herein. A sensor outputs data that is indicative of locations of multiple listeners in an environment. The data is processed to determine locations and orientations of the respective heads of the multiple listener in the environment. Based on the locations and orientations of heads of the listeners in the environment, for each listener, respective customized audio signals are generated. The customized audio signals are transmitted to respective beamforming transducers. The beamforming transducers directionally output customized beams for the first listener and the second listener based upon the customized audio signals and locations of the heads of the listeners. | 07-23-2015 |
20150208184 | DYNAMIC CALIBRATION OF AN AUDIO SYSTEM - Technologies pertaining to calibration of filters of an audio system are described herein. A mobile computing device is configured to compute values for respective filters, such as equalizer filters, and transmit the values to a receiver device in the audio system. The receiver device causes audio to be emitted from a speaker based upon the values for the filters. | 07-23-2015 |
20150208233 | PRIVACY PRESERVING SENSOR APPARATUS - A privacy preserving sensor apparatus is described herein. The privacy preserving sensor apparatus includes a microphone that is configured to output a signal that is indicative of audio in an environment. The privacy preserving sensor apparatus further includes feature extraction circuitry integrated in the apparatus with the microphone, the feature extraction circuitry configured to extract features from the signal output by the microphone that are usable to detect occurrence of an event in the environment, wherein the signal output by the microphone is unable to be reconstructed based solely upon the features. | 07-23-2015 |
20150373475 | Parametric Wave Field Coding for Real-Time Sound Propagation for Dynamic Sources - The techniques discussed herein may facilitate real-time computation and playback of a propagated signal(s) perceived at a listener location in a three-dimensional environment in response to reception of a desired anechoic signal at a source location in the three-dimensional environment. The propagated audio realistically accounts for dynamic signal sources, dynamic listeners, and effects caused by the geometry and composition of the three-dimensional environment. The techniques may parameterize impulse response(s) of the environment and convolve the anechoic signal with canonical filters at run-time in a manner that respects the parameters of the parameterized impulse response(s). The techniques also provide for real-time computation and playback of a propagated audio signal perceived at a listener location in a virtual three-dimensional environment responsive to generation of source audio signals generated at multiple source locations in the virtual three-dimensional environment. | 12-24-2015 |

20150033045 | Power Supply Droop Reduction Using Feed Forward Current Control - An apparatus for performing instruction throttling for a computing system is disclosed. The apparatus may include a first counter, a second counter, and a control circuit. The second counter may be configured to increment in response to a determination that a processing cycle of a processor has completed. The control circuit may be configured to initialize the first and second counters, detect the processor has issued and instruction, decrement the first counter in response to the detection of the issued instruction, block the processor from issuing instructions dependent upon the a value of the first counter, reset the first counter dependent upon a value of the second counter, and reset the second counter in response to a determination that the value of the second counter is greater than a pre-determined value. | 01-29-2015 |
20150362978 | HIERARCHICAL CLOCK CONTROL USING HYSTERISIS AND THRESHOLD MANAGEMENT - In some embodiments, a system may include a sub-hierarchy clock control. In some embodiments, the system may include a master unit. The master unit may include an interface unit electrically coupled to a slave unit. The interface unit may monitor, during use, usage requests of the slave unit by the master unit. In some embodiments, the interface unit may turn off clocks to the slave unit during periods of nonuse. In some embodiments, the interface unit may determine if a predetermined period of time elapses before turning on clocks to the slave unit such that turning off the slave unit resulted in the system achieving greater efficiency. In some embodiments, the interface unit may maintain, during use, power to the slave unit during periods of nonuse. The interface unit may maintain power to the slave unit during periods of nonuse such that data stored in the slave unit is preserved. | 12-17-2015 |
