摘要： According to one embodiment, a position location system includes a plurality of sensors, a time measurement unit, an angle calculation unit, and a position location unit. The plurality of sensors are arranged at a predetermined sensor interval. The time measurement unit measures a difference in time at which elastic waves arrive at the plurality of sensors. The angle calculation unit calculates an incident angle at which the elastic waves are incident on the plurality of sensors on the basis of the time difference. The position locator locates a source of the elastic waves on the basis of the incident angle. The predetermined sensor interval is a distance determined on the basis of a sound velocity of elastic waves propagating in a structure in which the plurality of sensors are arranged and a frequency characteristic of the sensor.

摘要： A method for recognizing infrasound events includes detecting infrasonic source using one or more microphone arrays each having three equally-spaced infrasound microphones. The method includes identifying, via a data acquisition system (DAS), a level of coherence of the detected infrasonic acoustic signals from each possible pair of microphones and recognizing the infrasound source using the coherence and a time history of the detected signals. The method may include estimating source properties via the DAS, including a magnitude, azimuth angle, and elevation angle, and executing a control action in response to the estimated properties. A system includes the array and the DAS. The array may be positioned above or below ground, and may be connected to one or more aircraft in some embodiments.

摘要： A transmitter subsystem periodically transmits ranging signals at transmit times, and a receiver subsystem receives the ranging signals at receive times within a receiver window having an adjustable time duration. A real-time position of a mobile device supporting one of the subsystems is determined based on differences between the receive and transmit times. An expected arrival time for the transmitted ranging signals is determined based on the real-time position of the mobile device. Each receive time is compared with the expected arrival time to obtain a consistency rate of the ranging signals that are received by the receiver subsystem directly from the transmitter subsystem. The time duration of the receiver window is dynamically adjusted based on the consistency rate.

摘要： An object detection device of the present disclosure includes three reception units for receiving reflected waves resulting from reflection of a transmission wave by an object within a detection range, and a determination unit for determining presence or absence of an object to be avoided based on outputs of the three reception units. The determination unit calculates first coordinates and second coordinates at which an object is estimated to be present, based on reception times from when a transmission wave is transmitted until reflected waves are received by the three reception units, and determines whether or not the object needs to be avoided, based on a distance between the first coordinates and the second coordinates.

摘要： A system may utilize sound localization techniques, such as time-difference-of-arrival techniques, to estimate an audio-based sound source position from which a sound originates. An optical image or depth map of an area containing the sound source location may then captured and analyzed to detect an object that is known or expected to have produced the sound. The position of the object may also be determined based on the analysis of the optical image or depth map. The position of the sound source may then be determined based at least in part on the position of the detected object or on a combination of the audio-based sound source position and the determined position of the object.

摘要： This invention provides a system and methods for tracking the positions and behaviors of moving objects such as animals. In one embodiment, the system comprises one or more tracking unit, one or more base nodes, one or more remote data hubs, and one or more remote processor with display. Each tracking unit (e.g. attached or inserted into the tracked animals) could transmit acoustic signal with a unique signature. The base nodes, after time stamping the received signals, relate the signals to the remote processors where the signals will be processed and the 3-dimensional spatial coordinates of the tracking units, and hence the animals, can be identified. Further processing of the positional information would reflect the activities and behaviors of each animal. Additional sensors included in the tracking unit provide further information about the states of the animals such as temperature, heart rate or blood pressure etc.
