Abstract: A method and system for mapping a target region (60) of space with signal scatterers. The method involves moving a signal transmitter (26) and/or signal receiver (46) along a respective trajectory (34, 54) relative to the target region, and meanwhile transmitting a probing signal (62) towards the target region, this probing signal including a a time sequence of noise (70) with a predefined bandwidth, receiving a response signal (76) composed of components resulting from scattering of the probing signal (62) by respective portions of the target region, and repeatedly determining positions (QT, QR) of the transmitter and/or receiver. The method further involves transforming the probing signal (62) into multiple test signals, each test signal being associated with a propagation path via a portion of the target region, and correlating each of the test signals with the response signal (76) in the time domain, to generate a map of correlation strength values associated with the portions of the target region.

Abstract: In one aspect, a method and system for detecting a change in fluid dynamics of a fluid flowing through an extra-corporeal circuit is disclosed, which includes establishing an acoustic wave resonance across a transverse dimension of at least a portion of a line associated with the extra-corporeal circuit through which the fluid flows, monitoring a phase signal of the resonant acoustic wave, and identifying occurrence of a change in fluid dynamics of the flowing fluid when the observed phase signal of the resonant acoustic wave indicates a deviation from the expected fluid flow signature. The change in fluid dynamics can be used to indicate a venous needle dislodgement event.

Abstract: A system and method for identifying available cargo space and allocating that available cargo space while in transit includes a plurality of sensors for measuring space from reference surface of a cargo container to pallets in the cargo container. Such distances are aggregated to identify unused space in real time. The unused space is used by a freight management system to identify cargo along the same route that can use the unused space.

Abstract: A fare gate in a transportation system including a barrier, a sensor, and an actuator. The actuator moves the barrier from the open position into the closed position. The sensor is mounted on the barrier and in one position captures sensor data across an aisle formed by the fare gate. A transit user in front of the barrier in another position is identified by the sensor. The transit user passes through the fare gate using the aisle. The actuator moves the barrier from a closed position to an open position to clear passage through the aisle. Using the sensor, the aisle is scanned with a movement of the barrier. The sensor is calibrated based on a predetermined point with movement of the barrier to align the sensor and the predetermined point.

Abstract: 一种超声波处理方法、装置、电子设备及计算机可读介质，涉及移动终端技术领域。该方法包括：通过超声波发送装置发送超声波信号，并通过超声波接收装置接收超声波信号在遇到物体后返回的超声波信号（S301）；获取由超声波接收装置接收的超声波信号，得到超声波信号的第一幅频数据（S302）；根据超声波分析模型的参数，将第一幅频数据映射为第二幅频数据（S303）；将第二幅频数据作为超声波分析模型的输入，以获取电子设备的运动状态（S304）；根据运动状态控制电子设备执行对应操作（S305）。因此，电子设备统一采用超声波分析模型以及映射后的第二幅频数据确定电子设备的运动状态，能够降低不同设备的超声波分析效果的差异性。
