  • Publication number: 20210075320
    Abstract: An electrical device includes an integrated circuit having device circuitry and a boost converter coupled to the device circuitry. The boost converter includes a digital integrator circuit having: a first comparator; a second comparator; a counter configured to count up, count down, and pause based on a first output signal provided by the first comparator and based on a second output signal provided by the second comparator; and a digital-to-analog converter (DAC) configured to provide a feedback adjustment signal for the boost converter based on a count value provided by the counter.

  • Patent number: 10904403
    Abstract: The present disclosure discloses methods, systems and scanners for scanning document with varying light intensity. The method includes receiving a bound document positioned on an upper surface of a platen, for scanning, wherein the bound document, when opened for scanning, includes a flat region and a curved region. A distance between the bound document positioned on the platen and a contact image sensor (CIS) is continuously monitored and measured, to detect the curved region. Upon detection, a control command is generated to vary the intensity of the light to be emitted from a light source. Then, light with varying intensity is emitted for illuminating the curved region of the bound document. Thereafter, the light reflected from the bound document is received for capturing an image of the bound document. Finally, a digital version of the bound document is generated without any dark strip or without any distortion.
