Because ultrasonic sensors are inexpensive and compact, they are used frequently. They are useful day and night. However, because the resolution is low, it is difficult to detect small steps, which are hazardous objects for electric wheelchairs. Next, passive type sensors include stereovision and ...
Interaction of the ultrasonic wave with the micro-crack helps in the detection and quantification of the precursor to damage in the material. The damage diagnosis and prognosis in the piezoelectric ceramics rely on the information of angular dispersion relationship, that is, directional changes in ...
