Abstract: The present disclosure relates to a location determination system that includes acoustic transmitting devices, location tags, and a wireless mesh network, where the wireless mesh network uses battery-powered devices. A location tag receives acoustic signals (e.g., ultrasound signals) from an acoustic transmitting device. Clocks from members of the wireless mesh network are synchronized by observation of clock pairings, each clock pair formed by respective clocks in a transmitting device that transmits a message and a receiving device that receives the message. By analyzing the observed clock pairings, a best fit between the clock pairings may be determined. After selecting a reference clock, an acoustic transmission schedule may be propagated to the respective acoustic transmitting device.

Abstract: Systems and methods for improved audio transmission of data payloads using segmented payloads are provided. In one embodiment, a method is provided that includes receiving data for transmission and dividing the data into multiple data segments. One or more headers may be appended to the data segments and used to form a first audio transmission. The first audio transmission may be transmitted as an audio signal within the audio environment. Another computing device may receive the audio transmission and may determine that the audio transmission contains a segmented data payload. In response, the computing device may identify segment headers within the audio transmission and may extract payload segments from the audio transmission based on the segment headers. A plurality of data segments may then be extracted from the payload segments.

Abstract: In an information management system according to the present invention, a measuring device including an output means including an oscillation device capable of generating ultrasonic waves causes the oscillation device to generate ultrasonic waves including identification information enabling the measuring device to be identified. An information terminal including a microphone capable of detecting the ultrasonic waves acquires the identification information from the ultrasonic waves via the microphone. The information terminal is caused to display the measuring device for which the identification information has been acquired. In a case where the information terminal receives an input indicating that the displayed measuring device is to be device-registered, the measuring device is device-registered on the information terminal.
