摘要： Systems, methods, and computer media for separating audio sources in a multi-microphone system are provided. A plurality of audio sample groups can be received. Each audio sample group comprises at least two samples of audio information captured by different microphones during a sample group time interval. For each audio sample group, an estimated angle between an audio source and the multi-microphone system can be estimated based on a phase difference of the samples in the group. The estimated angle can be modeled as a combined statistical distribution that is a mixture of a target audio signal statistical distribution and a noise component statistical distribution. The combined statistical distribution can be analyzed to provide an accurate characterization of each sample group as either target audio signal or noise. The target audio signal can then be resynthesized from samples identified as part of the target audio signal.

摘要： Systems, methods, and computer media for determining the angle of a target object with respect to a device are provided herein. Target object information captured at approximately the same time by at least two cameras can be received. The target object information can comprise images or distances from the target object to the corresponding camera. An angle between the target object and the device can be determined based on the target object information. When the target object information includes images, the angle can be determined based on a correlation between two images. When the target object information includes distances from the target object to the corresponding camera, the angle can be calculated geometrically.

摘要： A method and apparatus is provided for adjusting the gain imparted to a signal by an audio transducer such as a microphone and/or a speaker, which is employed by an electronic device having a multi-touch screen user input. The method begins when pressure applied to the multi-touch screen by a user is detected. The pressure is detected while the user is providing or receiving audible signals to or from, respectively, the audio transducer. Next, the user is identified based on a pre-established user profile that identifies the user based on a pressure profile that is obtained by the multi-touch screen. The pressure profile represents at least a contour of a portion the user's head such as the user's ear, cheek or the like. Once the user has been identified, pre-established user-selectable settings associated with the identified user are retrieved from memory. Finally, the gain imparted to the signal by the audio transducer is adjusted upward or downward based at least in part on the detected pressure and in accordance with the user-selectable settings.

摘要： A portable communication device (150) can include a transceiver (74) and a processor (76) coupled to the transceiver. The processor can be programmed to monitor at least one neighboring cell among a plurality of cells for a load condition on the at least one neighboring cell, monitor the at least one neighboring cell for a service capability and discontinue the monitoring of the at least one neighboring cell if a desired service capability fails to match the service capability of the at least one neighboring cell or if the load condition fails to meet a predetermined load condition. The processor can be further programmed to monitor the at least one neighboring cell for a signal quality indication and to discontinue the monitoring of the at least one neighboring cell if the signal quality indication falls below a predetermined threshold.

摘要： A radio device 100 includes: a speaker 130, which outputs audio signals, a microphone 129 that detects and receives audible sounds within the surroundings of the radio device; an audio volume/characteristic adjusting mechanism 125, which selectively increases and decreases the volume level or other audio characteristics of the audio signal outputted from the radio device based on a user input; and means (150) for dynamically adjusting the audio volume and other audio characteristics of the audio signal based on a stored relational mapping, which links a user adjustment of the audio volume/characteristic to a specific audible sound previously detected within the environment by the microphone 129, such that future detection of the audible sound by the microphone 129 triggers the dynamically adjusting of the audio volume (320) and other audio characteristics.
