Abstract: An acoustic vibration sensor, also referred to as a speech sensing device, is provided. The acoustic vibration sensor receives speech signals of a human talker and, in response, generates electrical signals representative of human speech. The acoustic vibration sensor includes at least one diaphragm positioned adjacent to a front port and at least one coupler. The coupler couples a first set of signals to the diaphragm while isolating the diaphragm from the second set of signals. The coupler includes at least one material with acoustic impedance matched to the acoustic impedance of human skin.

Abstract: Methods, systems and devices present information on a display in response to a user input received from an input device. One or more options are presented in a first portion of a user interface on the display, and a first user input indicating one of the options is received. In response to the first user input, a sub-menu of options associated with the indicated one of the first list of options is presented in a second portion of the user interface. In response to a second user input selecting the indicated one of the options, the sub-menu of options is presented in the first portion of the user interface. The various methods, systems and devices may be implemented in a media catcher system that selects and presents media content from one or more different sources.

Abstract: Methods, systems and devices are described for place shifting media content from a computer system to a remotely-located display over a network. The media content to be place shifted is captured at the computer system, wherein the media content includes a portion of imagery presented on a local display associated with the computer system. The captured media content is transcoded or otherwise converted to a media stream in a format that is transmittable on the network. The media stream is then transmitted on the network for presentation on the remotely-located display.

Abstract: Communication systems are described, including both portable handset and headset devices, which use a number of microphone configurations to receive acoustic signals of an environment. The microphone configurations include, for example, a two-microphone array including two unidirectional microphones, and a two-microphone array including one unidirectional microphone and one omnidirectional microphone. The communication systems also include Voice Activity Detection (VAD) devices to provide information of human voicing activity. Components of the communications systems receive the acoustic signals and voice activity signals and, in response, automatically generate control signals from data of the voice activity signals. Components of the communication systems use the control signals to automatically select a denoising method appropriate to data of frequency subbands of the acoustic signals.

Abstract: Voice Activity Detection (VAD) devices, systems and methods are described for use with signal processing systems to denoise acoustic signals. Components of a signal processing system and/or VAD system receive acoustic signals and voice activity signals. Control signals are automatically generated from data of the voice activity signals. Components of the signal processing system and/or VAD system use the control signals to automatically select a denoising method appropriate to data of frequency subbands of the acoustic signals. The selected denoising method is applied to the acoustic signals to generate denoised acoustic signals.
