  • Publication number: 20150172561
    Abstract: A handheld communication device is used to capture video streams and generate a multiplexed video stream. The handheld communication device has at least two cameras facing in two opposite directions. The handheld communication device receives a first video stream and a second video stream simultaneously from the two cameras. The handheld communication device detects a speech activity of a person captured in the video streams. The speech activity may be detected from direction of sound or lip movement of the person. Based on the detection, the handheld communication device automatically switches between the first video stream and the second video stream to generate a multiplexed video stream. The multiplexed video stream interleaves segments of the first video stream and segments of the second video stream. Other embodiments are also described and claimed.

  • Patent number: 8755536
    Abstract: A device includes a microphone array fixed to the device. A signal processor produces an audio output using audio beamforming with input from the microphone array. The signal processor aims the beamforming in a selected direction. An orientation sensor—such as a compass, an accelerometer, or an inertial sensor—is coupled to the signal processor. The orientation sensor detects a change in the orientation of the microphone array and provides an orientation signal to the signal processor for adjusting the aim of the beamforming to maintain the selected direction. The device may include a camera that captures an image. An image processor may identify an audio source in the image and provide a signal adjusting the selected direction to follow the audio source. The image processor may receive the orientation signal and adjust the image for changes in the orientation of the camera before tracking movement of the audio source.

  • Patent number: 8626148
    Abstract: An originating communications device is configured to transmit a text message to a recipient mobile device when the originating device determines that the recipient device has failed to connect with a call that was initiated by the originating device. The text message is designed to indicate that the recipient device has failed to connect with the call; in addition or as an alternative, the text message includes a code that indicates to the recipient device that it is potentially in a poor RF coverage area. The recipient mobile device, upon receiving and displaying the text message, may determine that it is indeed in an area with poor coverage and will in response store its current geographic location as a poor coverage area. Other embodiments are also described and claimed.
