摘要： The present invention relates to a system and a method for determining a distance between networked electronic devices each comprising a loudspeaker and a microphone. A first sound signal (300) comprising a first measuring wave (310) having a first frequency carried on a first carrier wave (320) having a first carrier frequency being higher than the first frequency is emitted by a first device (100a). A second device (100b) receives the first sound signal (300). The second device (100b) defines a second sound signal (350) comprising a second measuring wave (360) having the first frequency carried on a second carrier wave (370) having a second carrier frequency different from the first carrier frequency. A phase of the second measuring wave (360) is set such that it simulates a reflection of the first measuring wave (310) on the second device (100b). The second sound signal (350) is emitted by the second device (100b). The second sound signal (350) is received by the first device (100a). The distance between the first device (100a) and the second device (100b) is calculated based on a phase shift between the emitted first measuring wave (310) and the received second measuring wave (360).

摘要： The present invention relates to a technology for a sensor network, machine to machine (M2M), machine type communication (MTC), and internet of things (IoT). The present invention can be used in an intelligent service (a smart home, a smart building, a smart city, a smart car or connected car, health care, digital education, retail business, and security and safety related services) based on the technology. Specifically, according to various embodiments of the present invention, an electronic device can comprise an output unit, an input unit, and a control unit. The output unit can be configured to transmit a first sound wave. The input unit can be configured to receive a second sound wave from a different electronic device which receives the first sound wave. The control unit can be configured to determine a distance between the electronic device and the different electronic device based on a first value and a second value. The first value can correspond to a difference between a time point when the transmission of the first sound wave is started and a time point when the second sound wave is received, and the second value can correspond to a difference between a time point when the other electronic device starts the transmission of the second sound wave and a time point when the other electronic device receives the first sound wave.

摘要： Method and apparatus for determining the geophysical position of an autonomous underwater system utilizing underwater acoustic modems that exchange underwater acoustic signals. An exchange of broadband acoustic signals is initiated between the autonomous system of unknown geophysical position and a base system of known geophysical position wherein the depths of both systems is known. A bearing calculation is made on one of the signals transmitted between the systems with the use of an array of hydrophones on either the autonomous or base system. The range between the two systems is determined by measuring the time of travel of at least one signal. By the acoustic transmission and sharing of information about the known depths of the systems, the known geophysical position of the base system, and the range between the systems, sufficient data is gathered and used to determine the geophysical position of the autonomous system.

摘要： The invention relates to a device which is used for the global acoustic positioning of underwater devices (1) comprising positioning means for geographically referencing said device and a unit (6) for transmitting/receiving acoustic positioning signals. According to the invention, the acoustic signal transmitter/receiver (6) is an ultra-short baseline (USBL) system which generates n first position measurements, whereby n is the number of underwater devices (1) measured simultaneously and is greater than or equal to 1. Moreover, said device comprises: means for reconstructing the movements of the signal-delivery device (10), processing means (11) which receive all of the measurements in real time so as to determine the real position of the underwater device(s) (1), and means (12) for transmitting the real position of the underwater device(s) (1) in and/or out of the water.

摘要： A system, apparatus, and method for determining positions of underwater animals involves emplacement of an acoustic transponder on the animal and establishing communications with a transponder carried by a vessel whose position can be determined by receiving signals from an external source such as a GPS satellite in order to establish proximity of the animal to the vessel, the position of the vessel then being adopted as the position of the animal. Communications can be established either by communicating the position of the transceiver to the equipment on the animal for storage therein, or by communicating the identity of the animal to the vessel whose position has been determined for association with the position, and subsequent local storage on the vessel and/or communication to a central station.
