By applying the laser-linear array CCD detective technology, a high speed and high accuracy method for detecting roll wear is brought forward. The principle and composition of the detecting system has been expatiated. And a simulation-software program is compiled with Microsoft Visual Basic 6.0 based on this detecting principle. By using this simulation-software, the date of I/O signal for this system...
In this article we demonstrated a way to transport droplets by an arrowed micro-pillar array surface with hydrophobic parylene. We developed successfully that the lightly hydrophilic parylene surface can be changed to hydrophobic one treated with fluorine-based plasma (CF4 and SF6) for 10 seconds. Otherwise, we designed the ratchet pattern similar to the one proposed by A. Shasty in 2007. The droplet...
