Patent CA-2231430-C (CA)
Title: Motion compensated interpolation
Inventor: BORER TIMOTHY JOHN
IPC: H04N7/01
Filed: 1996-09-19
Granted: 2001-11-06
Abstract: This invention provides a way of performing improved motion compensated interpolation of moving images, such as television, using motion vectors of variable reliability. By taking into account the reliability of the motion vectors, produced by a separate motion estimation device, a subjectively pleasing interpolation can be produced. This is in contrast to simple motion compensated interpolation, taking no account of motion vector reliability, which is often degraded by objectionable switching artifacts due to unreliable motion vectors. The invention can be used, for example, to improve the performance of motion compensated standards converters used for converting between television standards with different picture rates. The invention allows a gradual transition between motion compensated and non-motion compensated interpolation depending on the reliability of the motion vector used. This is achieved by modifying the temporal interpolation timing, using a look up table, controlled by a vector reliability signal produced by the motion estimator. Effectively this adapts the motion trajectory of the interpolated output pictures.

Title: Slurry mixing apparatus and method
Inventor: POZNIAK PETER M
IPC: B01F25/46
Filed: 1998-10-14
Granted: 2005-06-14
Abstract: An apparatus and method for producing a slurry from a slurry concentrate in which streams of slurry concentrate, deionized water and oxidizer are pumped to form three pumped streams that are brought together to form a mixture. Homogeneity is promoted within the mixture by such devices as a static mixer and an in-line mixer of special design. The resultant homogenous stream is then pumped to dispense pressure by a dispense pump to produce a dispense stream. Part of the dispense stream, preferably about fifty percent, is recycled back to a junction at which the pumped streams join to further promote homogeneity of the slurry. For such a purpose a flow network is connected to an outlet pump and such flow network is branched so as to have a dispense leg from which the dispense stream issues and a recycle leg connected to the junction for recirculating the recycle stream.

The surface 1a of a single crystal .alpha.-SiC substrate 1 is adjusted so as to have a surface roughness equal to or lower than 2,000 angstroms RMS, and preferably equal to or lower than 1,000 angstroms RMS. On the surface  1a  of  the  single crystal  .alpha.-SiC  substrate  1,  a polycrystalline .alpha.-SiC  film  2  is  grown  by  thermal  CVD.          Thereafter, the complex M is placed a porous carbon container 3, and the outer side of the carbon container 3 is covered with .alpha.-SiC powder 4. The complex M is subjected to a heat treatment at a high temperature equal to or higher than a film growing temperature, i.e., in the range of 1,900 to 2,400°C in an  argon  gas  flow,  whereby single  crystal  .alpha.-SiC  is integrally grown on the single crystal .alpha.-SiC substrate 1 by crystal growth and recrystallization of the polycrystalline .alpha.-SiC film 2. It is possible to stably and efficiently produce single crystal SiC of a large size which has a high quality and in which any crystal nucleus is not generated.

Abstract: A method and apparatus for adaptively controlling the presence of copy protection signals in a video signal depends upon the scene content of the video signal during an upper portion of a display of the video signal. Thus, in the upper portion of the scenes, wherein picture information would be noticeably altered by a hooking process the copy protection process is deactivated or effectively reduced to eliminate or reduce the hooking or tearing effects. The adaptive control of the copy protection improves the playability performance of copy protected video signals on a very small minority of television receivers which display a small hooking or tearing characteristic in the upper portion of the display of the copy protected video signal.

Abstract: A dispensing device and method for forming at least partially solid or gel-like material from a liquid are described. In one example, at least one liquid issuing from an outlet is subjected to an electric field causing the liquid to form at least one electrically charged jet which, after formation, forms a fibre (F) or breaks up into fibre fragments (FF) or particles (D). The thus formed at least partially solid or gel-like material may be directly deposited, by virtue of the energy in the electrical field, onto a surface area, for example an area of skin enabling, for example, formation of a dressing for a wound or bum which is of high specific area and extremely absorbent. A biologically active ingredient such as for example a pharmaceutical ingredient or biological matter such as DNA may be incorporated into the fibres (F), fragments (FF) or particles (D). In another example, fibrils, particles or microcapsules incorporating a biologically active ingredient may be supplied for oral or nasal administration to an animal such as a human being.

Abstract: A waterproof joint system between tongue and groove wood planks sawn to bisect the heart of the small log they were made from. These planks are then planed into Greenwood planks, which will have exposed hearts on one side. Greenwood planks with hearts exposed will warp or cup as they dry with the cupping being away from the heart side. The green planks are interlocked together to form a wall or roof panel so that the heart side of the planks alternate from one side of the panel to the other. They are tied together by a series of cross ties nailed to each plank. Held tightly together the tongues will be forcefully squeezed against the sides of the grooves as the planks cup, producing a watertight joint. If the planks or logs are laid horizontally as with a log cabin, the cross ties will prevent the logs from settling, or newly designed long wood screws can be used as cross ties, which will also prevent settling and, unlike the cross ties, will be hidden in the wall.
