Time-of-Flight Measurement for Ultrasonic Sensors using Digital Signal Processing Techniques 1 Ultrasonic sensors measurements are mostly based on determination of time of flight (T.o.F). This paper presents a digital algorithm for obstacle detection and distance estimation using Pulsed Echo Ultrasonic ...
The launch of My Equipment Digital enables new functionality with digital collection and updating of industrial automation asset data through the use of network-based devices. The digital collection method includes firmware information and a one-time vulnerability assessment. Customers can self-manage and...
For a finite wavelength, wave transmitted through a medium that is heterogeneous on many scales, such delay times are only sensitive to the properties of the medium averaged over the dimensions of the first Fresnel zone11. Consequently, time-of-flight tomography is unable to resolve structure ...
