Publication number: 20240103906Abstract: A distributed scheduling system and a distributed scheduling method are provided. The distributed scheduling system includes a master scheduling platform and a slave scheduling platform. The number of the master scheduling platform and the number of the slave scheduling platform may be dynamically expanded respectively. When a back-end operating platform provides a scheduling data maintenance request to the master scheduling platform, the master scheduling platform provides scheduling data maintenance information to the slave scheduling platform according to the scheduling data maintenance request, so that the slave scheduling platform performs maintenance on scheduling data according to the scheduling data maintenance information. When a scheduling task execution condition of the scheduling data is met, the slave scheduling platform initiates a task, and calls a corresponding micro service to execute a business logic of the scheduling data.Type: ApplicationFiled: November 16, 2022Publication date: March 28, 2024Applicants: Digiwin Software Co., Ltd, DATA SYSTEMS CONSULTING CO., LTD.Inventors: Shih-Shuan Hung, Shiou Jye Lu, Dong Li, Guoxin Sun

Patent number: 6657607Abstract: Brightness in the LCD is enhanced by polarization recycling using a pre-polarizing film to pre-polarize light, and a special reflector for recycling light reflected by the pre-polarizing film. In one embodiment, the pre-polarizing film comprises a layer of DBEF brightness enhancement film, and the rear reflector is made of a PTFF material. In another embodiment, the rear reflector is covered with a film comprising barium sulfate. The multiple light sources are selected such that, at any color temperature within a predetermined range, the brightness of the LCD is not reduced below a given threshold minimum (e.g., 70 percent of the maximum brightness). Another constraint for selecting the light sources is that within the predetermined color temperature range, the color temperature is held close to the black body curve of the CIE chromaticity diagram. The light sources are also selected so that their maximum brightness point is set to be near the middle of the predetermined color temperature range.Type: GrantFiled: March 19, 2001Date of Patent: December 2, 2003Assignee: Silicon Graphics, Inc.Inventors: Daniel E.

Patent number: 4965672Abstract: A method and apparatus are disclosed for producing an image made up of marks having varying sizes, densities and/or shapes on an imaging media. The image is generated in response to image data defining the image to be produced received by an input scanner or other input device. The image data is processed and then used to address at least one amplitude and/or pulse width modulation table to, in turn, generate amplitude and pulse width signals which controls a writing device. Marks are therefore written onto the media, such marks having varying sizes, densities and/or shapes for forming the completed image.Type: GrantFiled: May 11, 1987Date of Patent: October 23, 1990Assignee: The Mead CorporationInventors: Ronald J.

Patent number: 4814799Abstract: A method and apparatus for creating a photomask corresponding to an image utilizes a planar disc having at least a portion of its surface formed from a photosensitive material. The disc is mounted for rotation. A laser beam source is supported at a spaced relationship with respect to the disc. One or more laser beams from the source are focused onto the disc. The laser source is moved radially with respect to the disc, whereby the laser beams scan the surface of the disc. The beams are modulated in accordance with information corresponding to the image to cause the image to be written onto the photosensitive material on the rotating disc by the laser beam.Type: GrantFiled: April 15, 1988Date of Patent: March 21, 1989Assignee: The Mead CorporationInventor: Sun Lu

Patent number: 4461715Abstract: A visual display device is featured which uses a new thermal addressing technique to provide a dark image upon a lighter background. The display is capable of being multiplexed to a large number of rows. The device comprises a cholesteric-smectic liquid crystal material mixed with a pleochroic dye of high order parameter. When the material experiences a transition from a higher to a lower, smectic thermal phase, two different textures or light states are developed; a transparent state and a light absorbing state. The transparent state is developed by applying a sensitizing voltage to certain portions of the medium. The pleochroic dye absorbs the light passing through the unsensitized portions of medium to provide the dark image. The row electrodes are made diffusely reflective so as to provide a double light pass through the medium to improve contrast.Type: GrantFiled: March 28, 1983Date of Patent: July 24, 1984Assignee: Minnesota Mining and Manufacturing CompanyInventors: Sun Lu, David B. Chung
