    Abstract: 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, and wherein at least some of the ultrasonic transducers that are activated are phase delayed with respect to other ultrasonic transducers that are activated. 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.

    Abstract: Multipath digital microphone systems comprising a multipath digital audio combiner component are described. Exemplary multipath digital microphone systems can switch from conveying one digital audio signal to conveying another digital audio signal based on one or more switching criteria determined by an exemplary multipath digital audio combiner component. Provided implementations can be configured to switch from conveying one digital audio signal to conveying digital audio signal according to an algorithm to provide low-power, high dynamic range digital microphone systems, without audible artifacts associated with conventional digital microphone systems.
