摘要： A distributed automatic level control function is provided, in which information relating to a common automatic level control parameter is transmitted to each of a plurality of microphone devices, wherein the information transmitted to at least one microphone device is derived from an audio sample of at least one different microphone device. Each microphone device produces the common automatic level control parameter based on the information received by the microphone device and applies the common automatic level control parameter produced by the microphone device to a distributed automatic level controller of the microphone device.

摘要： In a method for transmit beamforming of a two-dimensional array of ultrasonic transducers, a beamforming pattern to apply to a beamforming space of the two-dimensional array of ultrasonic transducers is defined. The beamforming space includes a plurality of elements, where each element of the beamforming space corresponds to an ultrasonic transducer of the two-dimensional array of ultrasonic transducers, where the beamforming pattern identifies which ultrasonic transducers within the beamforming space are activated during a transmit operation of the two-dimensional array of ultrasonic transducers, such that a generated ultrasonic beam is focused for reflecting from an object in contact with a contact surface of a platen overlying the two-dimensional array of ultrasonic transducers. The beamforming pattern is applied to the two-dimensional array of ultrasonic transducers. A transmit operation is performed by activating the ultrasonic transducers of the beamforming space according to the beamforming pattern.

摘要： A throat microphone may include one or more transducers that are in contact with the skin in the region of the larynx of person, and may provide a vibration signal to a processing unit. The vibration signal may also include energy and information relating to secondary physiological phenomena such as breathing and heartbeat, in addition to the desired sonic signal. The processing unit may utilize information relating to the secondary physiological phenomena to control a filter that outputs the desired sonic signal.
