Publication number: 20250065254Abstract: A method is provided for supporting environmental control in a semiconductor wafer processing space, the method includes: flowing a first gas under pressure in a first direction through a first diffuser tube, thereby generating a first lateral flow of gas through a sidewall of the first diffuser tube; flowing a second gas under pressure in a second direction through a second diffuser tube, thereby generating a second lateral flow of gas through a sidewall of the second diffuser tube, the second direction being opposite the first direction; combining the first and second lateral flows of gas within a housing; and outputting the combined lateral flows of gas from the housing to produce a laminar gas flow covering an opening to the semiconductor wafer processing space.Type: ApplicationFiled: November 12, 2024Publication date: February 27, 2025Inventors: Jyh-Shiou Hsu, Wen-Hsun Tsai, Chien-Chun Hu, Kuang-Wei Cheng, Sung-Ju Huang

Publication number: 20250056411Abstract: Various solutions for network power saving with respect to user equipment and network apparatus in mobile communications are described. An apparatus may receive a power saving indication. The apparatus may obtain power saving information according to the power saving indication. The power saving indication may comprise at least one of a discontinuous reception (DRX) switch indicator for switching between a user equipment (UE)-specific-DRX (U-DRX) and a group-specific-DRX (G-DRX), an energy saving mode (EMS) indication, a list of synchronization signal block (SSB) or channel state information-reference signal (CSI-RS) resources, and a set of transmission configuration indication (TCI)I states or RS resource indexes.Type: ApplicationFiled: April 28, 2023Publication date: February 13, 2025Inventors: Chien-Chun CHENG, Wei-De WU, Yi-Ju LIAO, Cheng-Hsun LI

Patent number: 7724971Abstract: Image compression, decompression and motion detection methods are described. Two temporally adjacent frame images, a previous time frame and a current time frame, are compressed in round-off and averaging techniques. Next, according to the compressed data of two corresponding pixels of the two frame images, whether or not the pixel of the current time frame image is of a motion picture is detected. If the pixel is of a motion picture, the compressed pixel data of the previous time frame image is decompressed, and an overdrive process is performed on the decompressed pixel data and the original pixel data of the current time frame image to produce an overdrive output. If the pixel is not of a motion picture, an overdrive process is not performed.Type: GrantFiled: July 29, 2008Date of Patent: May 25, 2010Assignee: Chunghwa Picture Tubes, Ltd.Inventors: Juin-Ying Huang, Wen-Tse Tseng, Chien-Hsun Cheng, Shih-Sung Wen

Patent number: 7262818Abstract: A video system that performs TV signal decoding, deinterlacing, and de-motion-blurring for progressive scan flat panel display is introduced. The system embeds a frame buffer and a scaler for conducting format and resolution conversions for display panels of different sizes. The output of the scaler is sent to a de-motion-blur processor for reducing the blurriness due to the motion of image objects and the slow response time of flat panel display devices. The de-motion-blur processor gets the motion and noise indication signal from scaler or the pre-frame-buffer video processor. Based on the motion and noise information and the information of temporal difference, the de-motion-blur processor performs over driving for the display panel interface and improves the rising and falling response time of the flat panel display. The decoding, deinterlacing, and de-motion-blur processing share the same frame buffer controller so the entire system can be optimized in cost and performance.Type: GrantFiled: January 2, 2004Date of Patent: August 28, 2007Assignee: Trumpion Microelectronic Inc.Inventors: Chun-Hsiung Chuang, Chien-Hsun Cheng, Shih-Sung Wen, Chi-Chuan Wang
