摘要： A robot cleaning system includes a robot cleaner comprising a sensor for receiving a specific signal sound, a rechargeable battery, and a control unit; and a recharging base comprising an audio output device for outputting the specific signal sound. The control unit calculates a distance and a direction from the robot cleaner to the recharging base based on the signal sound received by the sensor, and controls the robot cleaner to move based on the calculated distance and direction, when a remaining amount of the battery is less than a preset value. The robot cleaner docks with the recharging base to recharge the battery of the robot cleaner.

摘要： This document provides a method of determining an absolute position of a diver, comprising: providing a dive leader unit having a GPS receiver and an underwater acoustic modem configured to retransmit GPS coordinates of the dive leader unit under water, providing the diver with a monitoring unit comprising several microphones so that it is possible to detect a direction of the dive leader unit, pairing the monitoring unit to the dive leader unit to form a communication network so as to identify differences between system clocks of the dive leader unit and the monitoring unit and make it possible to calculate a distance from the dive leader unit to the monitoring unit. In the monitoring unit, the following steps are performed: receiving the retransmitted GPS coordinates, detecting the direction of the dive leader unit, calculating the distance to the dive leader unit, and calculating the absolute position of the diver based on the retransmitted GPS coordinates, the direction of the dive leader unit and the distance from the dive leader unit to the monitoring unit.

摘要： An exemplary apparatus includes one or more “communicators” that are worn, carried by, or otherwise associated with a person or location in an environment. Each communicator includes a synchronizable clock and a transmitter configured to transmit a message including a respective time stamp that is based on a time determined by the synchronizable clock. The message can be transmitted acoustically or in another manner such as by RF signal, optical signal, etc. The clock can be synchronized based on, e.g., a standard clock, another synchronizable clock associated with one or more transceivers, or a selected transceiver. The time stamp can be digital or analog, and can be configured to permit estimation of distance and bearing between synchronized communicators.

摘要： An acoustic tracking system designed to allow scientists and fishermen to follow dolphins and whales without harming or harassing them. The system utilizes six flow shielded hydrophones mounted on the bottom of a vessel in two arrays of three hydrophones in each array. Acoustic signals of interest (dolphin calls) which strike the hydrophone piezo-electric elements are transmitted to a receiver-display device which determines and displays both the bearing to the signal of interest and the relative range from the vessel to that signal. The receiver-display device utilizes digital microprocessors to determine the difference in signal arrival time of an incoming signal at pairs of hydrophones. The resulting computed bearing to the dolphin call is displayed as a lighted indicator on an electronic heading display. In addition, the digital microprocessors compare the received sound pressure level of incoming signals of interest and display the relative range as a series of lighted LED's on the electronic heading indicator.
