    摘要: Systems, an apparatus, and methods are provided for mitigating noise associated with an audio signal. A system (100) for mitigating noise associated with an audio signal includes an estimator module (108). The estimator module determines an estimated level of noise associated with the audio signal. The system also includes an expander module (110). The expander module causes an attenuation of the audio signal if a level of the audio signal is below a signal threshold. The expander module is adaptively tunable so that the attenuation caused (606) by the expander module is based upon the level of noise estimated (602) by the estimator module.

    摘要: The invention provides a cellular telephone or other communications device with intelligence to manage speakerphone operation to more nearly approximate normal conversation, even when using a one-way only transmission mode. The microphone path and speaker path may be continuously monitored using dual voice activity detectors to assess the energy and other characteristics of each channel, and switch between one or the other depending on dynamic criteria. In noisy environments, a hangtime may be applied before permitting switching to avoid premature dropouts. Other criteria used to trigger the seizure of the channel may be adjusted, such as to eliminate a lower threshold below which the speaker path switches out automatically.

    摘要: A hands-free digital push-to-talk device (102) includes a digital background noise suppressor (302), a digital voice activity detector (304), an audio buffer (306), as well as a decision handler (308), embedded inside the device's (102) digital signal processor (222). Audio is buffered until the decision handler (308) determines that speech is present on an audio stream fed to the voice activity detector (304). The decision handler (308) makes the decision by assigning weighted values to each voice activity detector (304) determination, the weighted value varying depending on the state of the device (102) and temporal distance from the present time.

    摘要: An IPC network (1900) allows for the dynamic composition of services. An IPC client (1902) can for example request a service, such as a new photo service, and teach the IPC network what service components comprise the service. The IPC server (1908) will wait until all of the required service components (1914, 1916) have registered with the IPC network (1900) prior to allowing the IPC client (1902) the go ahead to use the service. The dynamic composition of services allows clients/components operating in the IPC network (1900) to change service definitions without affecting the interprocessor communications between applications operating in the network (1900). Also, the IPC network (1900) learns dynamically the new service and is able to identify the availability of the service within the network (1900).

    摘要: An InterProcessor Communication (IPC) Protocol network (100) includes at least one IPC client (102) and an IPC server (108). The IPC protocol allows for the IPC client (102) to register with the IPC server (108) which will provide the means for the two to communicate freely without any limitations on what software architectures, operating systems, hardware, etc. each depend on. The IPC protocol in one embodiment of the invention provides for dynamic IPC node configuration in a server based IPC communication management framework.

    摘要: An IPC protocol in one embodiment of the invention includes smart hardware ports such as SSI port (1610). The session manager (1608) includes the capability for negotiating with components such as software threads (1602-1606) in order for a port (1610) to be dedicated to a particular task. The port dedication negotiation process allows for the session manager (1608) which is part of IPC stack (1610) to check for any conflicts the port may have with other op-codes currently dedicated to the port. The session manager (1608) can forward a command block along with the data received from each software thread. The command block informs the SSI port (1610) of any co-processing it may need to perform to the data.
