  • Publication number: 20230205416
    Abstract: A spatial position indication system includes an electronic pen, an indicated position detecting circuit, a spatial position detecting circuit, and a selecting circuit. The indicated position detecting circuit detects a position of the electronic pen at an input surface or a hover region over the input surface. The spatial position detecting circuit detects the position of the electronic pen in a spatial region including at least a part of the hover region separately from and independently of the indicated position detecting device circuit. Based on output from the indicated position detecting circuit and the spatial position detecting circuit, the selecting circuit performs selection control so as to use output from the indicated position detecting circuit or the spatial position detecting circuit according to a separation distance of the electronic pen from the input surface when a drawing image to be displayed on a display device is generated.

  • Publication number: 20220216790
    Abstract: In a DC-DC converter, a controller is configured to provide control cycles subsequently. Each of the control cycles includes a first ON-period and a second ON-period subsequent to the first ON-period. One switching element is turned on, and another switching element is turned off the first ON-period. The one switching element is turned off, and the another switching element is turned on for the second ON-period. A controller is configured to determine lengths of the first and second ON-periods based on high-side and low-side voltages. The controller is configured to turn on the one switching element in an initial ON-duration in the first ON-period of a control cycle among the control cycles which is firstly provided. The initial ON-duration has a length shorter than the determined length of the first ON-period. The controller turns off the one and another switching elements in a duration in the first ON-period in the first control cycle other than the initial ON-duration.
