  • Publication number: 20230055710
    Abstract: The present disclosure provides a proximity sensor. The proximity sensor includes a light emitting unit, a light receiving unit, a transimpedance amplifier, a capacitor, an amplifying unit, a converting unit and an integrating unit. The light emitting unit irradiates a detection target with light. The light receiving unit detects a reflected light from the detection target. The transimpedance amplifier receives an output of the light receiving unit. The capacitor receives an output of the transimpedance amplifier. The amplifying unit amplifies a difference between an output voltage of the capacitor when a charge corresponding to an ambient light is stored and the output voltage of the capacitor when charges corresponding to the ambient light and the reflected light are stored. The converting unit converts an output of the amplifying unit into a current signal and outputs the current signal. The integrating unit integrates an output of the converting unit.

  • Publication number: 20220371335
    Abstract: An inkjet printing method forming a decorative printed layer having a three-dimensional texture on a printing surface is described. The inkjet printing method includes: printing dots of curable ink that cure under a predetermined condition based on dot pattern data indicative of printed positions of the dots to be printed on the printing surface; and curing the printed dots. The dot pattern data indicates that: a distance between the adjacent dots becomes a distance where the adjacent dots before the curing are allowed to be maintained independently without bonding to one another in a first region; and the distance between the adjacent dots becomes a distance where the adjacent dots before the curing bond to one another in a second region different from the first region. Such a method may allow forming a decorative printed layer having a three-dimensional texture with a desired gloss level.
