  • Publication number: 20240134474
    Abstract: A display driver includes a driver circuit and a sensing controller. The driver circuit is configured to drive a display panel according to display information. The display panel defines a sensing region. The sensing controller interface circuit is configured to transmit an output vertical sync signal to a proximity sensing controller. The proximity sensing controller is configured to generate positional information of an input object based at least in part on a resulting signal received from a sensor electrode disposed in the sensing region. The output vertical sync signal comprises encoding the display information in the output vertical sync signal.

  • Publication number: 20240069671
    Abstract: In general, in one aspect, one or more embodiments relate to an input device that includes a proximity sensing panel including sensor electrodes, and a proximity sensing circuit. The proximity sensing circuit configured to receive an indication of a transition from a first image refresh rate to a second image refresh rate, wherein the first image refresh rate is greater than a beacon signal rate and the second image refresh rate is equal to or lower than the beacon signal rate. The proximity sensing panel is also configured to align transmitting a beacon signal on the proximity sensing panel to a non-refresh period corresponding to the second refresh rate.

  • Publication number: 20230416030
    Abstract: A sheet conveying apparatus includes a conveying unit, a drive source, a drive transmission unit, a tensioner, and a moving member. The drive source drives the conveying unit to convey a sheet. The drive transmission unit includes a drive transmission belt and a rotatable member to engage with the drive transmission belt. The drive transmission unit transmits a driving force of the drive source to the conveying unit via the drive transmission belt and the rotatable member. The tensioner moves between a pressing position at which the drive transmission belt is pressed and a retracted position retracted from the pressing position. The moving member moves the tensioner from the pressing position toward the retracted position. The magnitude of tension exerted on the drive transmission belt is lower when the tensioner is at the retracted position than when the tensioner is at the pressing position.

  • Patent number: 11274007
    Abstract: A sheet discharge apparatus includes a main tray, a discharge unit, and an expansion tray. The main tray is pivotable between a closed position and open position relative to a sheet discharge apparatus main body. The discharge unit discharges the sheet onto the main tray in the closed position. The expansion tray expands a main tray stacking area and is movable between a storage position where the expansion tray is stored in the main tray and an expansion position where the expansion tray is slid from the storage position in a sheet discharge direction and expands the stacking area. At the expansion position, the expansion tray is pivotable independently of the main tray. A direction in which the expansion tray is pivoted upward is the same as a direction in which the main tray is pivoted from the closed to the opened position.

  • Patent number: 10481536
    Abstract: The present invention relates to a fixing apparatus including a tubular film, a heater provided at an inside of the film, a protection element provided at the inside of the film, and at least one conductive member provided at the inside of the film. The protection element includes two terminals and a switch that turns off to shut off power to the heater when the heater abnormally generates heat. A first end of the conductive member is electrically connected to one of the terminals of the protection element. The conductive member is not coated with an insulator, and a second end of the conductive member projects out of the film so that the cost of the fixing apparatus is reduced.
