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 pseudo-random-noise sequence modulated onto a carrier signal, 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 (Qy, 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: Devices, systems, and methods may be used for wirelessly communicating underwater (or through air) with equipment such as, but not necessarily limited to, automatic swimming pool cleaners (APCs). Such communication avoids any need for conventional wired communication with the APCs. At least some of the devices may be hand-held and capable of having at least portions immersed in water in normal use. The devices preferably do not use radio frequency (RF) signal to communication with APCs, instead employing light-based or other signal types.

Abstract: An ultrasound imaging system may acquire short and/or undersampled radiofrequency ensembles for generating color Doppler images. The ultrasound imaging system may process the short and/or undersampled ensembles to simulate color Doppler images acquired from long radiofrequency ensembles. In some examples, the ultrasound imaging system may include a neural networks to process the ensembles. In some examples, the neural network may include two serial neural networks. In some examples, during training of the neural network, a power Doppler-based flow mask may be used on the output of the neural network. In some examples, during training of the neural network, an adversarial loss may be used on the output of the neural network.

Abstract: A semi-wave transducer is provided that comprises a circular or elliptic transduction shell that has sidewalls captured between identical opposing upper and lower circular or elliptic conical segments (platens), each having a surface geometry of a radially symmetric wave shape that includes a center region and a rim wherein the distance between the center region of the upper and lower platens greater than the distance between the rims of the upper and lower platens. In some embodiments, the surface geometry of the platens may be a jinc function or a recurve function.

Abstract: The present invention is directed to a transducer module including a two-piece protective assembly offering mechanical protection for one or more transducer elements (i.e., transmitter(s) and/or receiver(s)) provided within. The two-piece protective assembly comprises an internal rigid housing including a cavity formed by a set of walls or projections extending from a rear portion thereof. The cavity is shaped and/or sized to receive the one or more transducer elements within. The two-piece protective assembly further includes a cover overmolded and coupled to the rigid housing and sealing the one or more transducer elements within the cavity of the housing.

Abstract: An ultrasound system and method are provided for detecting lesions and/or abnormalities in a heterogeneous medium. An array of ultrasound transducer elements configured to emit ultrasound signals and to receive backscattered ultrasound signals. A processor performs a lesion detection algorithm that processes the backscattered ultrasound signals to obtain an Inter-element Response Matrix (IRM), splits the IRM into a plurality of sub-IRMs corresponding to subsets of the ultrasound transducer elements, and then performs additional processing that includes performing a depression detection algorithm to identify one or more lesions and/or abnormalities.

Abstract: A system for collecting data from multiple sensors at a central node is described. The system includes multiple pairs of sensor array multiplexers (SAMs) and sensors connected in series along the length of two cables each having a twisted wire pair. A first end of the length of the two cables is connected to the central node for receiving data from each of the multiple pairs. The multiple pairs include sensors of at least two different types, which may have different sampling rates. The first cable carries timing data between the multiple pairs and the central node and the second cable carries sensor data between the multiple pairs and the central node.

Abstract: Systems and techniques are described for gathering information on the health of individuals trapped in an accident to provide actionable information to a first responder system. In some implementations, a monitoring system monitors a property that includes sensors located at the property and generate first sensor data. A monitor control unit receives the first sensor data and generates an alarm event for the property based on the first sensor data. Based on generating the alarm event for the property, the monitor control unit dispatches an autonomous drone. The autonomous drone is configured to navigate the property. Using an onboard sensor, the autonomous drone generates second sensor data. Based on the second sensor data, the autonomous drone determines a location within the property where a person is likely located. The autonomous drone provides, for output, data indicating the location within the property where the person is likely located.
