20100123785 | Graphic Control for Directional Audio Input - A device to provide an audio output includes a microphone array, a signal processor, and a graphic user interface (GUI). The signal processor is coupled to the microphone array to perform audio beamforming with input from the microphone array. The GUI is coupled to the signal processor to display a plurality of audio sources, to receive a selection of at least one of the plurality of audio sources from a user, and to provide the selection to the signal processor for aiming the audio beamforming toward the selected audio source. The selection may be made by touching the display. The device may further include a camera and the GUI may display an image received from the camera as the plurality of audio sources. The camera may provide a moving video image and the signal processor may provide a synchronized audio signal aimed at the selected audio source. | 05-20-2010 |
20100128892 | Stabilizing Directional Audio Input from a Moving Microphone Array - 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. | 05-27-2010 |
20100183175 | Audio Player with Monophonic Mode Control - An audio player includes an audio headset having two earpieces. A playback circuit provides one of a stereophonic program and a monaural program to the audio headset. The monaural program may be created by mixing channels of the stereophonic program. A mode control is coupled to the playback circuit and to the audio headset. The mode control detects when at least one of the two earpieces is not adjacent a listener's ear and causes the playback circuit to deliver the monaural program to the audio headset. | 07-22-2010 |
20100216526 | Audio Jack with Included Microphone - A connector for receiving a cylindrical plug includes a body defining a plug aperture and a cavity for receiving the cylindrical plug. A plurality of electrical contacts in communication with the cavity make electrical connections with the cylindrical plug and retain the cylindrical plug. A microphone is coupled to the body such that the plug aperture and the cavity provide an acoustic path to the microphone. The microphone may be at an end of the connector opposite the plug aperture or on a side of the connector adjacent the plug aperture. The connector allows a microphone to be added to a device, such as a mobile telephone, without the need for an additional external aperture. The microphone in the connector may operate with a second microphone and processing electronics in the device to provide audio processing functions such as noise cancellation or audio beamforming. | 08-26-2010 |
20110164105 | AUTOMATIC VIDEO STREAM SELECTION - 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. | 07-07-2011 |
20120114133 | DETECTING THE REPOSITIONING OF AN EARPHONE USING A MICROPHONE AND ASSOCIATED ACTION - A system detects the repositioning of an earphone that is worn by a user, and changes an operation mode of a host coupled to the earphone. Within the earphone is a pressure transducer that detects a pressure change caused by the repositioning of the earphone. A signaling mechanism sends a repositioning detection signal to the host in response to a signal from the pressure transducer indicating the detection of the pressure change. | 05-10-2012 |
20120177239 | WIND NOISE PROTECTION - A removable case for a mobile communications device includes an opening that aligns with a microphone port that is built into the device. The case includes a windscreen that is sealed across the opening of the case. The windscreen is designed to reduce wind noise, air blasts, vocal plosives, and other noise. Other embodiments are also described and claimed. | 07-12-2012 |

20120238251 | Text Message Transmissions Indicating Failure of Recipient Mobile Device to Connect with a Call - 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. | 09-20-2012 |
20120272230 | POWER SAVING APPLICATION UPDATE IN A PORTABLE ELECTRONIC DEVICE - A power savings mode for data updates is provided. The power savings mode prevents data updates to occur while a screen of a portable electronic device is turned off and the device is in a sleep state. The power savings mode waits until the screen is turned on and the portable electronic device is in a wake state before allowing applications and widgets to update data from network repositories. By preventing applications and widgets from updating data while the portable electronic device is in a sleep state, the power savings mode conserves battery life and network bandwidth by limiting possibly unnecessary data transmissions. | 10-25-2012 |
