摘要： Various implementations described herein are directed to identifying reflected acoustic signals. In one implementation, a method may include receiving initial positions of an acoustic positioning source and an acoustic positioning receiver of an acoustic positioning system in a seismic spread. The method may also include calculating an expected travel difference between the acoustic positioning source and the acoustic positioning receiver. The method may further include receiving an acoustic positioning signal from the acoustic positioning receiver. The method may additionally include calculating an actual travel difference between the acoustic positioning source and the acoustic positioning receiver based on the acoustic positioning signal. The method may further include comparing the actual travel difference to the expected travel difference. The method may also include identifying whether the acoustic positioning signal is a reflected positioning signal based on the comparison.

摘要： A system to detect subsurface activity. The system employs vibration sensor pairs, with each sensor pair having a shallow sensor and a deep sensor. Outputs of the sensors of a pair are processed together and events are detected based on the relative values detected by the sensors of the pair. When signal energy departs from a detected background level, the relative amplitude and frequency content of vibrations measured at the shallow and deep sensors may be compared. The comparison may be performed, at least in part, using a classifier that discriminates between subsurface activity and surface activity. The outputs of sensor pairs may be aggregated to make a determination of whether subsurface activity exists and/or its location. Aggregation may involve comparing the outputs of the same sensor pair at multiple time intervals or may involve comparing the outputs of arrayed sensor pairs.

摘要： A method and system for determining the location of miners (2) trapped in an underground mine (4) that includes recording a reference seismic signature for each of a plurality of underground base stations (10) in the mine (4) in advance of an emergency. The reference seismic signatures are created by generating first a seismic signal with a high signal-to-noise ratio at each base station (10), monitoring the signal with a permanent array of surface seismic sensors (6), and recording each unique signature on a central computer. In the event of an emergency, trapped miners (2) can generate a second seismic signal at any of the underground base stations (10) which can be easily identified with the central computer by using the pre-recorded reference seismic signature to overcome a weak signal-to-noise ratio.

摘要： The present invention is directed towards an acoustic concealed item detector and related methods for detection using acoustics. In an illustrative embodiment, a multi-frequency ultrasonic wave generator generates in a gaseous medium at least first and second ultrasonic waves. The multi-frequency ultrasonic wave generator is arranged such that in operation, the first ultrasonic wave and the second ultrasonic wave mix in a prescribed mixing zone to produce a difference-frequency acoustic wave. A receiver sensor detects the difference-frequency acoustic wave and produces corresponding electromagnetic signals. The electromagnetic signals are processed by a system processor and signals indicative of concealed items are identified. Preferably the ultrasonic waves are focused to a small prescribed mixing zone. Parametric and multi-transducer embodiments are disclosed.

摘要： A method is described for detecting the presence of at least one foreign object (41,42) in or on a human or animal body (30), by analysing ultrasonic reflection signals (R1, R2, R3, Rx). The method comprises the steps of: sending an ultrasonic emission signal (S) through the air to the body (30) to be examined; receiving reflection signals (R; R1, R2, R3, Rx); analysing the received reflection signals. If the reflection signal ® contains suspicious reflection components (Rx) which are indicative for foreign objects, an alarm signal is issued.

摘要： The beginning detection, accommodation and frequency bias properties of the human hearing mechanism have been modeled to create systems that can detect directional transients s("sound event") in a sound field and separately localize them. These models break down a sound field into sound events and non-sound events and separately localize the sound events and non-sound events. Sound events are generally identified according to the frequency bias and beginning detection properties. Once detected, sound events are generally localized according to differential steering angles (steering angles to which the steady-state signals have been accommodated) or ordinary steering angles and which reflect the direction of a sound event indicated in its rise-time. When no sound events are detected, non-sound events are localized according to a steering angle that does not reflect rapid motion.
摘要翻译：人类听觉机构的开始检测，调节和频偏特性已经被建模，以创建可以在声场中检测定向瞬变（“声音事件”）的系统并且分开地定位它们。这些模型将声场分解为声音事件和非声音事件，并分别定位声音事件和非声音事件。声音事件通常根据频率偏差和起始检测属性来识别。一旦检测到，声音事件通常根据不同的转向角（已经容纳了稳态信号的转向角）或普通的转向角定位，并且反映了其上升时间所指示的声音事件的方向。当没有检测到声音事件时，非声音事件根据不反映快速运动的转向角进行定位。
