  • Patent number: 9866938
    Abstract: A microphone system includes a first transducer deployed at a first microphone; a second transducer deployed at a second microphone, the first microphone being physically distinct from the second microphone; a decimator deployed at the second microphone that receives first pulse density modulation (PDM) data from the first transducer and second PDM data from the second transducer and decimates and combines the first PDM data and the second PDM data into combined pulse code modulation (PCM) data; and an interpolator deployed at the second microphone for converting the combined PCM data to combined PDM data, and transmits the combined PDM data to an external processing device.

  • Patent number: 9830080
    Abstract: An analog signal is received from an acoustic transducer. The analog signal is converted into digital data. A determination is made as to whether acoustic activity exists within the digital data. The digital data is stored in a temporary memory storage device and a count is maintained of an amount of digital data in the temporary memory storage device. When the count exceeds a predetermined threshold, at least some of the digital data is transmitted from the temporary memory storage device to a processor.

  • Patent number: 9799215
    Abstract: A method of operating an acoustic system includes detecting an ultrasonic sound signal and pattern matching the received ultrasonic sound signal to determine when the received ultrasonic sound signal is a desired ultrasonic sound signal. The method includes sending a signal to at least one electronic component when the received ultrasonic sound signal is the desired ultrasonic sound signal. The method includes operating the microphone in a lower power state when the received ultrasonic sound signal is not the desired ultrasonic sound signal.

  • Publication number: 20170046117
    Abstract: An acoustic apparatus includes a first digital microphone having a first clock pin, a second digital microphone having a second clock pin, an application processor having a third clock pin, a first interface that couples the first digital microphone and the application processor, and a second interface that couples the first digital microphone, the second digital microphone, and the application processor. The acoustic apparatus further includes a clock that connects to the first clock pin, the second clock pin, and the third clock pin, wherein first data is transmitted on a first clock edge, and wherein second, different data is transmitted on a second other clock edge.

  • Patent number: 4021622
    Abstract: A nonlocking key telephone station is arranged to display full line status information when the station is on-hook and for normally illuminating only the key lamp associated with the line in use at the station when the set is off-hook. To permit a user to discern the full status of the lines terminating at the set when the set is off-hook, circuitry responsive to the depression of one of the keys at the station is provided for displaying full line status information.
