Abstract: Enhanced systems and methods for collision avoidance of a high value asset with reflective beacons around it using multi-sensor data fusion on a mobile industrial vehicle. The system has a sensing processing system with a LiDAR and camera sensors, and a multi¬ processor module responsive to the different sensors. The sensing processing system fuses the different sensor data to locate the reflective beacons. A model predictive controller on the vehicle determines possible control solutions where each defines a threshold allowable speed for the vehicle at discrete moments based upon an estimated path to a breaching point projected from the reflective beacons, and then identifies an optimal one of the control solutions based upon a performance cost function and associated with an optimal threshold allowable speed. The system has a vehicle actuator configured to respond and alter vehicle movement to avoid a collision when the vehicle exceeds the optimal threshold allowable speed.

Abstract: A method for an ultrasonic time-of-flight flow meter (1) includes driving an ultrasonic transducer (2, 3) using a first waveform (V 1 (t)) for a first duration (Δt 1 ) , the first waveform ( V 1 ,(t)) configured to cause oscillation (21) of the ultrasonic transducer (2, 3), The method also includes driving the ultrasonic transducer (2, 3) using a second waveform ( V 2 (t) ) for a second duration ( Δt 2 ) . There is a discontinuity between the first waveform ( V 1 (t)) and the second waveform ( V 2 (t) ). The second waveform (V 2 (t)) and the second duration ( Δt 2 ) are configured to maintain a voltage (V t -(t)) across the ultrasonic transducer (2, 3) within a predetermined range ( V h , V L ).

Abstract: A method for use in acoustic imaging, comprising: transmitting, from a transmitter, a first sound wave pulse at a first frequency determined by a maximum sampling rate of a receiver; transmitting at least one second sound wave pulse at a frequency substantially equal to the first frequency, the first and at least one second sound wave pulses being transmitted substantially within a fraction of a sample interval of the receiver; receiving and sampling, at the receiver, a reflection of at least two of the first and at least one second pulses to generate a set of receiver samples; and expanding the set of receiver samples, based on the first frequency and a total number of the first and at least one second pulses transmitted, to generate an expanded sample set with a larger number of samples than the set of receiver samples.

Abstract: Methods, systems, and devices for acoustic structural reflection interference mitigation are provided in accordance with various embodiments. For example, some embodiments may provide for structural reflection interference mitigation for compact three-dimensional ultrasonic anemometers. Some embodiments include a method that may include transmitting a first acoustic signal from a first acoustic transmitter. At least a first portion of the first acoustic signal from the first acoustic transmitter may be hindered from being received at a first acoustic receiver. At least a second portion of the first acoustic signal from the first acoustic transmitter may be received at the first acoustic receiver along an acoustic propagation path. In some embodiments, the first acoustic transmitter may include a wide-beam transmitter. Some embodiments may utilize four wide-beam transducers positioned at apices of a tetrahedron.
