  • Patent number: 8421425
    Abstract: A current detector for an output load includes a high side power transistor; a low side power transistor coupled to the high side power transistor; and a controller coupled to the high and low side power transistors to provide cycle by cycle control of the conduction of the high and low side power transistors, wherein if the controller detects zero or negative current in the output inductor, using a dead time between when the low side power transistor turns off and before the high side power transistor turns on, the low side power transistor is held off during the entirety of the next switching cycle.

  • Patent number: 8242813
    Abstract: Systems and methods are disclosed to detect current for an output load with an inductor. The system includes a high side power transistor a low side power transistor coupled to the high side power transistor; and a controller coupled to the high and low side power transistors to provide cycle by cycle conduction of the low side power transistor, said controller adaptively turning off the low side power transistor when the high and low side power transistors are off and an inductor current is non-positive. Adaptation of the turn off of the low side transistor is based on the time position of the detection of the non-positive inductor current and serves to improve the power efficiency of the system.

  • Publication number: 20080048951
    Abstract: The present invention describes a method and apparatus for measuring the voltage and current characteristics of the OLED pixel as it ages and correlating the measured data to the decrease in quantum efficiency and changes in OLED impedance over the life of the OLED, so that corrections can be made to the image drive system to prevent image sticking and color point drift. The method and apparatus of the present invention do not require any additional circuitry or changes in the display design. The circuitry of the present invention is implemented in the display driver integrated circuit (IC) chips. The basis of the invention is the luminance-current-voltage (LIV) curves which characterize the OLED materials over their life time. A series of these curves are stored in memory representing a OLED material at various ages.

  • Publication number: 20070257012
    Abstract: A method and an apparatus for processing workpieces with a laser beam include first and second stages for holding the workpieces and first and second laser beam paths. The first workpiece is loaded upon the first stage, aligned with the first laser beam path, and processing begun. While the first workpiece is aligned in relation to the first laser beam path, the second workpiece is prepared in relation to the second laser beam path. Processing of the second workpiece is begun as soon as the laser beam is available for processing.
