| 141 | Filtering method and apparatus for reducing block artifacts or ringing noise | EP15152375.0 | 2003-01-29 | EP2894856A1 | 2015-07-15 | Park, Jeong-hoon; Kim, Yong-je; Lee, Yung-lyul |
A filtering method and apparatus for removing blocking artifacts and ringing noise. The filtering method includes transforming video data in a block-by-block basis, and detecting the presence of an edge region in the video data by checking the distribution of values obtained by the transformation. Accordingly, it is possible to completely remove blocking artifacts and/or ringing noise by more effectively detecting the presence of an edge region in video data.

| 146 | DEVICE FOR TRANSMITTING A FORCE, IN PARTICULAR A COMPRESSION FORCE, ALONG A SUBSTANTIALLY STRAIGHT PATH | PCT/EP1998/002073 | 1998-04-09 | WO98046903A1 | 1998-10-22 | |
| In a device for transmitting a force, in particular a compression force, along a substantially straight path, the compression force should be transmitted with little wear and noise by an elongated and articulated transmission element capable of bending to one side. For this purpose, a toothed belt (1) is used having teeth (2) on one side and block-like projections (10) shaped one after the other on the back side (7) of the toothed belt in the longitudinal direction (11) of the toothed belt. During transmission of the compression force, these blocks lie next to each other on the straight path (4). | ||||||

| 148 | Gapped core type reactor | JP9156693 | 1993-04-19 | JPH06302440A | 1994-10-28 | NISHIMURA ISAO; MISHIMA AKIRA |
| PURPOSE: To reduce vibration noise by making the Young's modulus of the gap material arranged at the center in the direction of stacking of block iron cores or the gap material arranged at the inside or outside periphery of the block material lower than the gap material in other sections. CONSTITUTION: A plurality of block iron cores 2 circular in cross section are constituted by stacking silicon steel plates radially into annular shape, and an iron core leg 1 provided with gaps is constituted by stacking these block iron cores 2 through magnetic gap materials 3. This is an iron core type reactor provided with gaps where winding 4 is wound around this iron core leg 1 fitted with a diode, and the iron core leg 1 provided with gaps circular in cross section and yoke iron cores 5 and 6 rectangular in cross section are fixed integrally. And, out of these gap materials 3, the Young's modulus of the gap material 3b at the center in stacking direction is made lower than that of the gap material 3a at both ends in the stacking direction of block iron cores 2. Hereby, vibration noise and magnetostrictive noise by compressive force can be reduced. COPYRIGHT: (C)1994,JPO | ||||||

| PROBLEM TO BE SOLVED: To reduce pattern noises, while keeping high drivability. SOLUTION: The hardness of cap rubber 30 is made softer than usual hardness (54 degrees) and the surface of a block-like tread portion 18 is covered and reinforced by a fiber-reinforced rubber layer 28 mixed with short fibers 32 to thereby ensure the block rigidity of the block-like tread portion 18. When the block-like tread portion 18 hits a road surface, hitting noises are reduced and pattern noises are reduced. Since the block rigidity of the block-like tread portion 18 is sufficiently ensured by reinforcing the fiber-reinforced rubber layer 28, the block-like tread portion 18 is prevented from falling to ensure a contact area with the ground, which can ensure high drivability.

| 156 | HYDRODYNAMIC SLUG FLOW MODEL | US13869269 | 2013-04-24 | US20130317791A1 | 2013-11-28 | Thomas J. DANIELSON |
| A very simple model has been presented which is able to reproduce slug flow from the instability of a flow with average hold-up and slip. The disclosure demonstrates that slug flow may be modeled as two different, stable solutions to the multiphase flow which coexist at different points in the line, moving with a celerity of UG. By using a white-noise inlet condition which preserves the average hold-up in the pipeline, a series of stable slug and stratified regions can be created without any need to resort to a Lagrangian slug tracking scheme. A quite good fit to field data was obtained with minimal effort by adjusting the slip relation. At present, the model merely demonstrates a potential, very attractive, flexible, and easy-to-implement alternative to Lagrangian slug tracking. | ||||||

| Digital noise removal methods and systems for picture quality improvement on next generation high quality set-top-box and digital TV SOCs is disclosed with particular to a de-blocking method and system that is effective on on-grid and off-grid blocky artifacts generated by lossy video compression standards. Blocky artifacts are filtered by extracting motions vectors for a current pixel block, calculating off-grid positions based on the extracted motion vectors, and applying de-blocking filtering along the calculated off-grid positions. The methods and systems can further skip filtering on-grid blocky artifacts to be filtered by an on-grid de-blocking filter known in the art. | ||||||

High-frequency noise is generated that approximates the appearance of traditional "film grain" for a digital video signal. By adding a relatively small amount of film grain noise, the video can be made to look more natural and more pleasing to the human viewer. The digital film grain generation can be used to mask unnatural smooth artifacts in digital video such as "blockiness" and "contouring" in the case of compressed video and/or used to provide visual enhancements or special effects to any digital video stream. The digital film grain generator can control grain size and the amount of film grain to be added.
