We propose a system to measure the dimensions of carton boxes carried on a conveyer belt with an accuracy of 5mm, required in logistic applications. Our system estimates the dimensions through a series of depth images with relatively low resolution taken by unsynchronized multiple sensors. To achieve the accuracy, we first obtain the dimensions via the distance between parallel planes instead o...

We propose a method of conveyor belt longitudinal tear dynamic line edge detection based on CCD digital image processing. CCD camera captured video frames of conveyor belt at a certain frequency, we first applied median noise filtering and binarization to preprocessing the motion images of conveyor belt on the condition that they were not degenerative. Then Canny edge detection operator detecte...

INTRODUCTION Noncontact transfer devices are demanded when silicon wafers or glass plates are carried in clean environment. Because contact of such products with a conveyer belt damaged their surface, non-contact transfer devices are needed for the use in clean environment. Many transfer devices using ultrasonic, electromagnetic or electrostatic levitation have been proposed. The authors also h...

is paper presents wireless sensing systems to increase safety and robustness in industrial process control, particularly in industrial machines for marble slab working. e process is performed by abrasive or cutting heads activated independently by the machine controller when the slab, transported on a conveyer belt, is under them. Current slab detection systems are based on electromechanical ...

We consider a carbon nanotube gated slightly away from the half-filled π-band, in the presence of an externally applied periodic potential. We show that the electron states can become locked by the potential when the electron density (counted from half-filling) corresponds to a rational number of electrons per potential period. At such densities, excitation gaps open up in the spectrum. When ga...
