    Abstract: A digitizer suitable for digitizing input signals having a high dynamic range. The digitizer is microprocessor controlled and comprises an input stage, a multi-channel attenuator or amplifier bank, a multiplexer and a analog-to-digital (A/D) converter. The function of the multi-channel bank is to move the input signal within the range of the A/D converter. The input signal to be digitized is fed through the input stage to each of the channels in the attenuator bank. The signal is scaled by each respective channel in the attenuator bank. The multiplexer is used to switch the scaled signal which is within the range of the A/D converter for digitizing. The digitized sample is then corrected according to the attenuation or gain factor of the scaled channel. The digitizer includes a comparator bank which is used to determine the channel with the widest signal range within the range of the A/D converter. The digitizer also includes a channel calibrator for calibrating the actual gain or attenuation of each channel. In another aspect, the digitizer can be implemented using an optical front-end comprising an optical beam splitter, optical attenuators and amplifier banks. The optical front-end provides improved noise immunity and faster speed of operation.

    Abstract: An optical scanner has a light distributor rotating about an axis spaced from but parallel to the optical axis of at light source. Lenses are mounted on a carrier that rotates about the optical axis. The distributor and carrier rotate a the same angular velocity and are arranged so that the lens and associated distributor move across the media at the same time. By rotating the lens about the optical axis, the scanning beam remains in the central zone of the lens as it passes across the media.

    Abstract: Methods and devices to compensate for image color variance due to display temperatures are provided. In one example, a display of an electronic device may include a first pixel section that has multiple pixels. The pixels may include a red subpixel, green subpixel, and blue subpixel that each has a respective aperture ratio. The display may also include a second pixel section that has multiple pixels. Again, the pixels may include a red subpixel, green subpixel, and blue subpixel that each has a respective aperture ratio. One or more of the subpixel aperture ratios of the first pixel section may be greater than a respective one or more of the subpixel aperture ratios of the second section to overcome image color variance that may exist due to temperature variations of the display.
