摘要： The present invention relates to a microphone apparatus (10) with a main beamformer (F, BF) that provides a directional audio output (SF) by combining microphone signals (X, Y) from multiple microphones (11, 12).The quality of beamformed microphone signals normally depends on the individual microphones having equal sensitivity characteristics across the used frequency range. The invention enables automatic adaptation of the main beamformer (F, BF) to variations in microphone sensitivity and to changes in the alignment of the microphone apparatus (10) with respect to the user's mouth (7).This is achieved by having the microphone apparatus (10): estimate a suppression filter (Z) for an optimum voice-suppression beamformer (Z, BZ) based on the microphone signals (X, Y); estimate a candidate filter (W) for a candidate beamformer (W, BW) as the complex conjugate of the suppression filter (Z); estimate the performance of the candidate beamformer (W, BW); and replace a main filter (F) in the main beamformer (F, BF) with the candidate filter (W) if the candidate beamformer (W, BW) is estimated to perform better than the current main beamformer (F, BF).The invention may be used to enhance speech quality and intelligibility in headsets 1 and other audio devices that pick up user voice.

摘要： An apparatus (301) for communication according to a Universal Serial Bus, USB, specification, comprising: a first USB device (301) and a second USB device (306) for connecting operatively to a first USB host and a second USB host, respectively; an audio interface stage (320) configured to interface with an audio component such as a headset; and audio controller (316).The audio controller (316) is configured with: a first channel (327), channeling audio signals between the first USB device and the audio interface stage (320), and a second channel (328), channeling audio signals between the second USB device and the audio interface stage (320); wherein the audio controller (316) automatically switches between the first channel (327) and the second channel (328) while giving priority to audio signals on the first channel over audio signals on the second channel.Thereby respective software programs, among which one requires priority access to the audio component, running on one hardware apparatus, such as a personal computer, or on separate hardware apparatuses can be operatively connected to respective USB devices while sharing one audio component and while giving one of the respective software programs priority access to the audio component.

摘要： A system and method of creating a steady ON and a special effects light effect from a bulb without providing any special wiring thereto. In one embodiment, the bulb contains an illumination element and a controller which produces the special effect in the element. By interrupting the flow of current to the controller periodically, the controller is initialized to its initial steady ON condition. A plurality of steady ON pulses at a high frequency will appear as a steady ON light, instead of pules, thereby producing a steady ON appearance without special wiring. When the current is allowed to flow continuously, the controller produces the special effect. A second embodiment uses parallel polarized light element which produce different effect when power is applied in opposite polarities, thereby providing two effects with no special wiring.

摘要： A headset for voice communication is disclosed, the headset comprising at least one earphone having a speaker and one or more microphones. The headset is configured to be operated in a first mode in which an electronic noise cancelling circuit is configured to receive ambient audio via at least a first of the one or more microphones to implement an active noise cancelling function and to provide a noise cancelling audio signal to the speaker, and in a second mode in which ambient audio is provided as a hear-through audio signal to the speaker. The headset for voice communication is configured to detect whether a call is ongoing, and to provide a call signal in response to the detection. The headset comprises the electronic noise cancelling circuit, a voice activity detection unit configured to indicate when a user speaks, a switching element configured to switch the headset between operating in the first mode and operating in the second mode, wherein, when the headset is operated in the first mode and the call signal indicates that the user is not in a call, the switching element is configured to switch the headset from operating in the first mode to operating in the second mode when the voice activity detection unit indicates that the user speaks.
