Abstract: A portable voice capture device having an orientable arm comprising a first leg and a second leg, the first leg and the second leg having different orientations, the first leg of the first arm comprising a first differential linear array of microphones, a directivity of the first differential linear array being arranged for improved sensing of voice from a user, the second leg of the arm comprising a second differential linear array of microphones, a directivity of the second differential linear array being arranged for improved sensing of noise from a different than the direction of said sensed voice, and a noise reduction circuit for providing a voice signal with reduced noise, based on the output of the first array and on the output of the second array.

Abstract: A portable voice capture device comprising: an orientable arm with a first differential array of microphones comprising at least one pair of microphones, the directivity of said first array being arranged for sensing voice from a first direction depending on the orientation of said arm; a second differential array of microphones comprising at least one pair of microphones, the directivity of said second array being arranged for sensing noise from a second direction different from the first direction; a noise reduction circuit for providing a voice signal with reduced noise, based on the output of said first array and on the output of said second array.

Abstract: A system, computer program and method for transmitting requested data from a data source in response to data transmission requests from at least one electronic device according to differential rates of throughput. Data transmission requests are classified into one of a plurality of throughput classes, with each throughput class having an assigned rate of throughput. A proportion of data transmission requests to be processed from each throughput class is selected such that each data transmission request has a rate of throughput approximating the assigned rate of throughput of its class. The requested data is then sent from the data source to the electronic device.
