  • Publication number: 20120268021
    Abstract: A multi-channel LED driving system includes a power adapter, a rectifying and filtering unit, a plurality of LED strings, and a plurality of linear regulators, a CC/CV controller, an optically coupled isolator and a PWM controller. The CC/CV controller detects the conducting currents flowing though the LED strings and DC voltage source outputting from the rectifying and filtering unit, and provides voltage compensation of the power adaptor. In addition, the linear regulators slightly modulate the current difference between the LED strings to achieve current-sharing control, thus stabilize the illuminating brightness generating by the LED.

  • Publication number: 20110235924
    Abstract: After receiving a digital image, check if the digital image contains a predetermined object. If the digital image contains the predetermined object, extract object features from the predetermined object, then compare the object features with common features of each of the predetermined identifications. If the object features match the common features of one of the predetermined identifications, store the digital image into a database dedicated to the predetermined identification. If the object features do not match the common features of any of the predetermined identifications, register the predetermined object with a new identification. If the new identification is the same as one of the predetermined identifications, store the digital image into a database dedicated to the predetermined identification. If the new identification is different from all of the predetermined identifications, store the digital image into a database dedicated to the new identification.
