Ultrasonic communication system for communication through RF-impervious enclosures and abutted structures

摘要

An ultrasonic communication system comprising an enclosure, a first module and a second module is described. The enclosure has an internal surface, an external surface, and defines at least one metal channel. The first module comprises an ultrasonic transceiver disposed within the enclosure. The first module is positioned on the internal surface of the enclosure and is capable of transmitting and/or receiving modulated ultrasonic waves via the metal channel. The second module is positioned on the external surface of the enclosure and is adapted to transmit and/or receive modulated ultrasonic waves from the first module via the metal channel.

主权项

1. An ultrasonic communication system, comprising:
a first enclosure having at least one first steel corner post comprising at least one first channel capable of transmitting modulated ultrasonic waves; one or more first modules comprising an ultrasonic transceiver positioned onto the at least one first channel; a second enclosure having at least one second steel corner post comprising at least one second channel capable of transmitting modulated ultrasonic waves; one or more second modules comprising an ultrasonic transceiver positioned onto the at least one second channel; and wherein the first enclosure and the second enclosure are positioned in an abutting interface connecting the at least one first channel of the at least one first steel corner post and the at least one second channel of the at least one second steel corner post, and wherein the first module and the second module communicate using the at least one first channel and at least one second channel to transmit modulated ultrasonic waves in a frequency range between near 280 kHz and approximately 330 kHz.
