  • Patent number: 12589392
    Abstract: A pattern electrode structure for an electrowetting device is laminated between a base material and a dielectric layer of the electrowetting device, and the pattern electrode structure includes first branch electrodes formed in a direction perpendicular to any plane perpendicular to a plane defined by the pattern electrode structure, and a basal pattern electrode formed in an area below lower ends of the first branch electrodes and connected to an electrode connection portion configured to receive a voltage, in which a sum of an interval between the first branch electrode and the basal pattern electrode and a width of the basal pattern electrode is larger than a diameter of a droplet to be removed, thereby preventing the droplet from stagnating without falling at the terminal end of the pattern in a structure that uses the vertical pattern.
    Type: Grant

  • Publication number: 20250053000
    Abstract: An embodiment pattern electrode structure for an electrowetting device includes a first branch electrode disposed in a direction perpendicular to any plane that is perpendicular to a plane defined by the pattern electrode structure and a basal pattern electrode disposed in an area above an upper end of the first branch electrode and connected to an electrode connection portion configured to receive a voltage, wherein an interval between the first branch electrode and the basal pattern electrode is equal to or larger than a diameter of a droplet to be removed.

  • Patent number: 8104599
    Abstract: A hand-operated control lever release apparatus for a transmission of a vehicle includes a housing, a manual release lever rotatably mounted in the housing, a brake cam which is rotatably coupled to the housing through the cam shaft and the rotation of which is restrained by the manual release lever, a first cable connecting the manual release lever to a control lever for the transmission and unlocking the control lever in response to rotation of the manual release lever, and a second cable connecting the brake cam with a brake pedal. According to the apparatus, the control lever for the electronic transmission can be manually unlocked in response to rotation of the manual release lever, thereby actuating the movement of the vehicle.
