Method and system for transmitting information using ultrasonic messages

摘要

A device includes an audio capture device for receiving an audio signal in an ultrasonic frequency range. The device includes a processor to determine whether the received audio signal corresponds to an ultrasonic message. The processor extracts a content of the ultrasonic message, when it is determined that the received audio signal corresponds to an ultrasonic message, automatically handles the ultrasonic message based on the extracted content, stores at least a portion of the content of the ultrasonic message, and displays the portion of the content of the ultrasonic message to a user of the mobile device at a time subsequent to a time of the receipt of the audio signal.

主权项

1. A device, comprising:
an audio capture device for receiving an audio signal in an ultrasonic frequency range; a storage; and a processor to:
determine whether the received audio signal corresponds to an ultrasonic message;extract a content of the ultrasonic message, when it is determined that the received audio signal corresponds to an ultrasonic message,wherein the content of the ultrasonic message comprises at least a message type identifier and message data;automatically handle the ultrasonic message based on the extracted content;store at least a portion of the content of the ultrasonic message in the storage; anddisplay the portion of the content of the ultrasonic message to a user of the device at a time subsequent to a time of the receipt of the audio signal,wherein the processor to automatically handle the ultrasonic message is further to:
maintain a plurality of ultrasonic message handling rules, each ultrasonic message handling rule having a message type identifier and a destination identifier;search the plurality of ultrasonic message handling rules based on the message type identifier in the ultrasonic message to identify a matching ultrasonic message handling rule; andforward the message data of the ultrasonic message to a destination identified by the destination identifier in the matching ultrasonic message handling rule.
