  • Advances in High Speed Automated Optical Inspection (AOI) Systems (.pdf)
    Recent advances in machine vision technologies and motion control present tremendous opportunities for Automated Optical Inspection (AOI) systems. Thanks to recent developments in these fundamental building block technologies, today's AOI systems can carry out inspections with a higher resolution

  • Rotary encoders for motors
    Constant-speed ac-induction motors don't really hold a constant speed. In an optical encoder, an LED typically shines light through a code disk and mask to illuminate a photodetector assembly. The slots in the disk and mask form a shutter that passes or blocks the light beam as the code disk
  • Integrated Drive Electronics for Brushless DC Motors
    for an angular position sensing system can include electro-optical switches (optical. encoders), most commonly a combination of light emitting diode (LED) and a phototransistor. A shutter. mechanism controls light transmission between the transistor and the sensor. The sensor voltages can. be processed
  • Case Study: A Smarter View of China's ITS Infrastructure
    shutter sensors, high speed interfaces and a Software Development Kit provided by camera manufacturers such as Allied Vision Technologies. Interline Frame Transfer CCDs and Global shutter CMOS devices have eliminated the dependence on a mechanical shutter; a necessity for ITS system providers who
