Abstract: Noise cancellation systems and methods are provided that generate an anti-noise signal configured to destructively interfere with noise in a cancellation zone. The systems and methods receive a signal representative of the noise in the cancellation zone. The signal is analyzed to identify a frequency to be reduced in the cancellation zone, and the signal is down converted to place the identified frequency at baseband. A baseband anti-noise signal is generated based upon the down converted signal. The baseband anti-noise signal is up converted to the identified frequency to produce an anti-noise signal having components at the identified frequency, and the anti-noise signal is provided to be transduced into an acoustic signal.
Abstract: A wearable electronic device (WED) corrects an error where a user hears binaural sound. A processor processes sound into binaural sound that localizes to the user at a location, and the WED determines a gaze direction of the user when the user hears the binaural sound. The WED corrects an error between the location and the gaze direction.
Abstract: On the basis of a bitstream (P), an n-channel audio signal (X) is reconstructed by deriving an m-channel core signal (Y) and multichannel coding parameters (?) from the bitstream, where 1?m<n. Also derived from the bitstream are pre-processing dynamic range control, DRC, parameters (DRC2) quantifying an encoder-side dynamic range limiting of the core signal. The n-channel audio signal is obtained by parametric synthesis in accordance with the multichannel coding parameters and while cancelling any encoder-side dynamic range limiting based on the pre-processing DRC parameters. In particular embodiments, the reconstruction further includes use of compensated post-processing DRC parameters quantifying a potential decoder-side dynamic range compression. Cancellation of an encoder-side range limitation and range compression are preferably performed by different decoder-side components. Cancellation and compression may be coordinated by a DRC pre-processor.

Abstract: Each of one or more commit cycles may be associated with a predicted number of updates. A statistics collection time for a database table can be determined by estimating a sum of predicted updates included in one or more commit cycles. Whether the estimated sum of predicted updates is greater than a first threshold may be determined. In addition, a progress point for a first one of the commit cycles can be determined. A time to collect statistics may be selected based on the progress point of the first commit cycle.

Abstract: A system comprising audio processing circuitry is provided. The audio processing circuitry is operable to receive audio signals. The audio processing circuitry is operable to process the audio signals to detect strength of a chat component of the audio signals and strength of a game component of the audio signals. The audio processing circuitry is operable to automatically control a volume setting based on one or both of: the detected strength of the chat component, and the detected strength of the game component. The combined-game-and-chat audio signals may comprise a left channel signal and a right channel signal. The processing of the combined-game-and-chat audio signals may comprise measuring strength of a vocal-band signal component that is common to the left channel signal and the right channel signal.

Abstract: An active noise control device includes a control signal generating unit including a first adaptive filter configured to generate a control signal by performing a filtering process on a reference signal corresponding to noise, an identifying unit configured to identify a peak frequency in an impedance frequency characteristic of an actuator, a peak frequency storage unit configured to store an initial peak frequency of the actuator, a first determination unit configured to determine whether or not a difference between the peak frequency currently identified and the initial peak frequency is greater than or equal to a threshold value, and a control unit configured to change a characteristic of the control signal generated by the control signal generating unit when the first determination unit determines that the difference is greater than or equal to the threshold value.
Abstract: An acoustic customization system to enhance a user's audio environment. One type of enhancement would allow a user to wear headphones and specify what ambient audio and source audio will be transmitted to the headphones. Added enhancements may include the display of an image representing the location of one or more audio sources referenced to a user, an audio source, or other location and/or the ability to select one or more of the sources and to record audio in the direction of the selected source(s). The system may take advantage of an ability to identify the location of an acoustic source or a directionally discriminating acoustic sensor, track an acoustic source, isolate acoustic signals based on location, source and/or nature of the acoustic signal, and identify an acoustic source. In addition, ultrasound may be serve as an acoustic source and communication medium.
Abstract: An arcing detection system detects arcing within a semiconductor processing cleanroom environment. The arcing detection system includes an array of microphones positioned within the cleanroom environment.

Abstract: Embodiments relate to a system, method and program product for performing code conversions. In one embodiment the method includes determining size of encoding space for a source file and a target file upon receipt of a code conversion request and generating a main conversion file upon determination that a target encoding space associated with said target file is smaller than a source encoding space associated with the source file. Subsequently an extension converted file is generated from the source file according to a pre-established mapping table of code conversion stored in a memory. The code conversion request is completed by using the main conversion file and said extension file together so that the source file does not need to be truncated in order to fit into the target conversion space.

Abstract: Representative embodiments disclose mechanisms for data and identity migration, such as from an on-premises environment to a cloud environment. The system comprises multiple data collectors, each tailored to collect data from a data source. In a representative example, data collectors for a source application, a source identity repository and a target identity repository are utilized. Once the data is collected, it is stored in a database and methods are used to identify correlations (i.e., matches) between the source application data, the source identity repository data and the target identity repository data. The correlations are memorialized and presented to a user for rationalization. The process is stateful so that prior decisions are remembered. Once the user is satisfied with the rationalization, the system exports files that are consumed by a migration process to perform the actual data migration.

Abstract: An acoustic device according to the present technology includes an operating portion and a control unit. The operating portion generates information for determining whether a state of an earphone portion is a wearing state in which the earphone portion is worn by the user, or a non-wearing state in which the earphone portion is not worn by the user. The control unit determines whether the earphone portion is in the wearing state or in the non-wearing state on the basis of output from the operating portion, and implements a function based on a result of the determination.
