An inspection design method and procedure by which mobile robots can inspect large pipe structures has been demonstrated with the successful inspection of multiple defects on a three-meter long steel ...

The study of surface acoustic wave (SAW) sensors and devices encompasses a vibrant field in modern engineering and physics, where acoustic waves propagating along the surface of a piezoelectric ...

Each VPU contains an acoustic sensor which is housed within a hermetically sealed chamber that blocks out all ambient noise. As a result, when a VPU is placed on a surface such as a tabletop, it is ...

At the heart of every camera is a sensor, whether that sensor is a collection of light-detecting pixels or a strip of 35-millimeter film. But what happens when you want to take a picture of something ...
