  • Ultrasonic communication system
    Patent number: 10447410
    Abstract: A sensor network includes a sink and multiple sensor nodes. The sink is coupled to a substrate and configured to transmit a periodic ultrasonic pulse on the substrate. A first one of the sensor nodes is coupled to the substrate. The first sensor node is configured to (i) receive the periodic ultrasonic pulse from the substrate, (ii) synchronize an internal clock of the first sensor node to the sink based on the periodic ultrasonic pulse, (iii) selectively detect an event in a region surrounding the first sensor node, and (iv) in response to detecting the event, transmit a first ultrasonic pulse toward the sink on the substrate.
