    • This disclosure describes audio techniques that exploit a prioritization scheme of audio streams of a software application, such as a video game that execute on a mobile device. The priority of the audio streams are defined by a content creator of the application. In addition, priority of an additional audio stream not associated with the application (such as an audio alert) is also defined. A mobile device includes a processor that executes the application and an audio decoding unit that receives a plurality of prioritized audio streams of an application executing on a mobile device, receives an additional prioritized audio stream not associated with the application, and combines a subset of the prioritized audio streams associated with the application and the additional prioritized audio streams according to priority to form a common audio stream.

    • An enhanced blind source separation technique is provided to improve separation of highly correlated signal mixtures. A beamforming algorithm is used to precondition correlated first and second input signals in order to avoid indeterminacy problems typically associated with blind source separation. The beamforming algorithm may apply spatial filters to the first signal and second signal in order to amplify signals from a first direction while attenuating signals from other directions. Such directionality may serve to amplify a desired speech signal in the first signal and attenuate the desired speech signal from the second signal. Blind source separation is then performed on the beamformer output signals to separate the desired speech signal and the ambient noise and reconstruct an estimate of the desired speech signal. To enhance the operation of the beamformer and/or blind source separation, calibration may be performed at one or more stages.
    • 提供增强的盲源分离技术来改善高度相关的信号混合物的分离。 波束形成算法用于预处理相关的第一和第二输入信号,以避免通常与盲源分离相关联的不确定性问题。 波束成形算法可以对第一信号和第二信号应用空间滤波器,以便在衰减来自其它方向的信号的同时放大来自第一方向的信号。 这种方向性可以用于在第一信号中放大期望的语音信号,并从第二信号中衰减所需的语音信号。 然后对波束形成器输出信号执行盲源分离,以分离所需的语音信号和环境噪声,并重构所需语音信号的估计。 为了增强波束形成器和/或盲源分离的操作,可以在一个或多个阶段执行校准。

    • The embodiments of present invention provide method for imparting tone-controlled colors into colorless crystals such as gemstones or decorative objects by coating a atomically mixed thin film comprising of a color causing reagent and a toner material onto the surface of colorless gemstones or transparent crystals and subjecting them to a heat treatment to produce colors of desired shades in the crystals. The method employed is radiation-free, eco-friendly and avoid the use of any hazardous material. The method highlights that controlling the amount of toner material could easily control the shade of color induced by the colorant material. The coating of atomically mixed single film onto the surface of crystals results in reduction of diffusion time significantly at a reasonable temperature, to impart colors to crystals such as gemstones and colorless decorative objects.

    • In one embodiment, a mobile station such as a dual-mode, AMPS and CDMA, handset communicates with an AMPS base station in a wireless communication system. The mobile station includes an acoustic echo canceller, which can detect acoustic echo, for example, feedback from the handset speaker to the handset microphone, during communication between the mobile station and the base station, and cancel or eliminate the acoustic echo. The mobile station also includes a network echo suppressor coupled to the acoustic echo canceller. For example, the network echo suppressor can read a parameter set by the acoustic echo canceller. The network echo suppressor attenuates or mutes a network echo caused by portions of the communication returning to the mobile station from the base station after a network propagation delay. Coupling the network echo suppressor to the acoustic echo canceller ensures proper interaction between the network echo suppressor and acoustic echo canceller.
    • 在一个实施例中,诸如双模AMPS和CDMA之类的移动站与无线通信系统中的AMPS基站通信。 移动台包括声学回声消除器,其可以在移动台和基站之间的通信期间检测声学回声,例如从手机扬声器到手机麦克风的反馈,以及消除或消除声学回声。 移动站还包括耦合到声学回声消除器的网络回波抑制器。 例如,网络回波抑制器可以读取由声学回波消除器设置的参数。 在网络传播延迟之后,网络回波抑制器衰减或静音从基站返回到移动站的部分通信引起的网络回波。 将网络回波抑制器耦合到声学回声消除器,确保网络回波抑制器和声学回声消除器之间的正确交互。
