7 results about "Dual Scan" patented technology

Dual Scan, also known as dual-scan supertwist nematic or DSTN, is an LCD technology in which a screen is divided into two sections which are simultaneously refreshed giving faster refresh rate than traditional passive matrix screens. It is an improved form of supertwist nematic display that offers low power consumption but inferior sharpness and brightness compared to TFT screens. For several years (late '90s to early 2000s), TFT screens were only found in high-end laptops due to them being more expensive and lower-end laptops offering DSTN screens only. This was at a time when the screen was often the most expensive component of laptops. The price difference between a laptop with DSTN and one with TFT could easily be $400 or more. However, TFT gradually became cheaper and has essentially captured the entire market.

ActiveCN121132024BLaser beam welding apparatusBeam trajectoryTorque motor
This invention discloses a laser engraving system and method for a high-ink-capacity ceramic anilox roller, relating to the field of ceramic roller laser engraving, aiming to solve the problems of limited ink capacity and low production efficiency in existing technologies. The system includes a laser head, a ceramic roller, and a cell observation instrument, and also includes modules for cell image acquisition, test point positioning, engraving control, analysis, and sub-scanning planning. The laser head includes a laser, a high-frequency torque motor, etc. The high-frequency torque motor can drive the movement of a reflector to adjust the laser beam trajectory. The method generates anilox data, positions cells and test points, matches laser power to engrave test points, compares data output strategies, and dynamically adjusts the sub-scanning trajectory before engraving. This invention adopts a dual-scanning trajectory, combined with real-time visual feedback to adaptively control laser power and trajectory, to achieve fine cell engraving, improve ink capacity, ink transfer uniformity, and production efficiency, and avoid ceramic damage.

Ripple-like image segmentation optimization method driven by edge enhancement and region features

This invention proposes a ripple-like image segmentation optimization method driven by edge enhancement and region features. The proposed "ripple mechanism" refers to a modeling strategy that uses edges and regions as structural centers, progressively spreading semantic features through direction perception and structural interaction. This mechanism mainly consists of two parts: a scan enhancement module and a nested state weight key-value network (NSKV). The scan enhancement module includes edge enhancement, region enhancement, and interactive dual scan modules for multi-directional, multi-level modeling of local and structural features. The state weight key-value network is a sequence modeling structure with state preservation capabilities, integrating the memory and attention mechanisms of recursive modeling. This invention can model long-range dependencies and temporal context information while maintaining high computational efficiency, thereby improving overall structure perception and segmentation accuracy.
