Publication number: 20240131271Abstract: A drive train for a wind-up injection device is described. The drive train includes a torsional energy storage adapted to be loaded or unloaded by a rotatable element, a rotatable user handle, a rotationally driveable expelling mechanism adapted to expel the liquid drug, and a clutch element coupled with the torsional energy storage via the rotatable element and including a ratchet for maintaining the rotatable element at one of a number of discrete angular positions against the torque of the torsional energy storage. The clutch element is adapted to transmit the torque from the user handle to the torsional energy storage, or alternatively from the torsional energy storage to the expelling mechanism. The ratchet is switchable from one position to an adjacent position by a torque transmitted from the user handle to the torsional energy storage. The drive train is adapted to dampen torque peaks visco-elastically and/or visco-frictionally.Type: ApplicationFiled: December 8, 2023Publication date: April 25, 2024Inventors: Michael Jugl, Stefan Blancke, Axel Teucher, Ralph Donald Quentin Collings, James Robert Coop, James Anthony West, Stephen Francis Gilmore, Daniel David Higgins, Mark Digby Teucher, Anthony Paul Morris, Matthew Meredith Jones, William Geoffrey Arthur Marsh, Samuel Keir Steel

Patent number: 9417479Abstract: Facilitating the display of an image in a display system comprising a display panel having sub-pixels, and a backlight having individually addressable colored light emitters configured to provide light to the sub-pixels. From received image data, sub-pixel color values corresponding to color values transmitted by respective ones of the sub-pixels for display of the image are determined. From the image data, backlight values corresponding to brightnesses of ones of the colored light emitters for display of the image are determined, as are a portion of the sub-pixel color values and a portion of the backlight values that collectively correspond to a saturated or near-saturated yellow color in the displayed image. The backlight values are adjusted by increasing an amount of yellow light to be emitted by emitters of the backlight, and the color values are adjusted by decreasing an amount of yellow light to be transmitted by the sub-pixels.Type: GrantFiled: April 2, 2013Date of Patent: August 16, 2016Assignee: Samsung Display Co., Ltd.Inventors: Joel M.

Patent number: 8633952Abstract: In a first embodiment, a display system comprises a display panel with 4 or more colored subpixels. The display system receives input image data specified in a first color space and outputs image data specified in a second color space. The display system further comprises a gamut mapping module for mapping the input image data specified in the first color space to image data specified in the second color space. The gamut mapping module clamps out-of-gamut colors using at least a first clamping system and a second clamping system. The first and second clamping systems yield first and second clamped values.
