Abstract: Control system for devices such as an audio reproduction system, an actuator device, an electromechanical device and a telephony device. The system includes control circuitry that receives an input signal and a signal indicative of a position of a portion of the controlled apparatus. The control circuit provides an output signal to the controlled apparatus to affect an operation of the controlled apparatus. The output signal provides control of the apparatus to compensate for one or more of: motor factor; spring factor; back electromotive force; and impedance of a coil in a driver of the controlled apparatus. The signal indicative of position is derived by one or more position indicator techniques such as an infrared LED and PIN diode combination, position dependent capacitance of one portion of the controlled apparatus with respect to another portion of the controlled apparatus, and impedance of a coil in the controlled apparatus.

Abstract: The present invention provides a method and system for reducing flicker within an interlaced image. The method and system comprises identifying an area of the interlaced image where flicker needs to be reduced and adaptively adjusting a pattern of pixels derived from a non-interlaced spatial relationship of the interlaced image within the area based upon characteristics of the image. A flicker filter is provided which utilizes an adaptive technique whereby pixel-blending characteristics are constantly changed within the image depending on particular image attributes. It is unique in that high vertical resolution is maintained for detailed image content such as text and most graphics, while flicker is effectively reduced on image content that is flicker prone. The filter is based on psycho-visual studies and simulations performed by the company as well as numerous prior flicker filter implementations.

Abstract: A system and method for reducing flicker in a display system using a flicker reduction circuit. The display includes a series of scan lines, each of which includes a set of pixels. The display is controlled by a video signal, which includes a series of video lines containing control variables that control the intensity of the pixels in the corresponding scan line. In one embodiment of the flicker reduction circuit, the flicker reduction circuit receives two of the video lines as input, and delays one of the one video lines using a memory, such that its control variables are synchronized in time with the other undelayed video line. The difference between the intensity of the synchronized pairs of control variables is determined, and the difference is fed into a look-up table. Based on the difference, the look-up table provides a control value that is then applied to one of the original synchronized control variables to provide a modified control variable that reduces flicker on the display screen.
