A new type detection device for the suspended flyer was developed to test the press finger and performance parameters of the flyer. The device was made up of mechanical transmission, control and signal processing part, which realized full automation of measurement by wireless transmission technology. Hybrid driven differential adjustable framework was employed in the device, so the bobbin windi...

OBJECTIVE Tympanostomy tubes (TTs) are commonly rendered nonfunctional by mucus plug formation. The purpose of this study was to determine whether an in vitro model could be developed to assess TT plug formation with results consistent with human trials. STUDY DESIGN An ear chamber was designed to mimic middle ear air and mucus flow conditions in post-TT otorrhea. TT occlusion was tested and ...

The goal of design is to expedite the movement of the dynamic focusing unit which can increase the scanning speed, area, and accuracy simultaneously. Figure 2 shows that the design of a proposed dynamic focusing unit with using Voice Coil Motor (VCM). The focusing lens is fixed on the yoke and the moving lens is mounted on the bobbin and is moving when the VCM working. The focused spot is moved...

Accurate and consistent determination of flawed regions in steam generator tubing is becoming increasingly important as nuclear power plants age and repair costs increase. The general problem of assessing the structural integrity of steam generator tubing using eddy current inspection is rather complex due to the presence of noise and interference signals under different inspection conditions. ...
