Title: Method and apparatus for encoding video shape and texture information
Inventor: OSTERMANN JOERN
IPC: H04N7/30
Filed: 1999-01-26
Granted: 2003-01-14
Abstract: An encoding apparatus and method adjust texture information for a video object based on original shape information for the video object. The original shape information is not encoded shape information or information that has been encoded and then decoded. In a preferred embodiment, the texture information is adjusted by 0 padding pets near the boundary of the video obj ect in an inter mode, or by lowpass extrapolation filtering pets near the boundary of the video object in an infra mode where the boundary of the video object is defined by the original shape information. Lossy shape encoding can therefore be performed while decreasing the overall encoded bit rate, improving the subjective appearance of the decoded video object and decreasing computational complexity of the encoder and/or encoding method. Adaptive scanning and subsampling of macroblocks can be avoided while having little effect on overall bitrate and significantly decreasing computational complexity of the encoding process.

Abstract: The apparatus has an intermediate conveyor (18) with conveying elements (26) distributed in the circumferential direction on bearing plates (36). Each conveying element (26) has a roller segment (54), which is driven counter to the direction of circulation (U), and a belt conveyor (56)-which is assigned to said roller segment. A control device (48) keeps the conveying elements (26) in a mutually parallel position during circulation in the direction of circulation (U). During movement past the receiving location (16), a rear section (82) of the roller segment (54) and the belt conveyor (56) form an introduction gap (24) for a product (14) fed by a feed conveyor (12) in each case. During further rotation, said product (14) is moved through the conveying element (26), in the conveying gap (90) now formed by the roller segment (54) and belt conveyor (56), and is deflected by means of the guide element (92). At the transfer location (50), the product (14) is thus introduced into a gripper (96) of a removal conveyor (52), whereupon the conveying gap (90) is eliminated. The apparatus, while maintaining the sequence of the products (14), changes the position of the latter such that the sides (20, 20') of the products (14), said sides facing one another in the fed imbricated stream (S), are changed round.

Granted: 2004-01-06
Abstract: A submicrometer transition metal carbonitride is produced having the formula : MaM'bM''(1-a-b)(C(1-x)Nx)z, wherein M is Ti, Zr or Hf; M' is V , Nb or Ta; M'' is Cr, Mo or W; a ranges from 0 to 1; b ranges from 0 to 1 with the proviso that (a+b) is less than or equal to 1; x ranges from 0.02 to 0.95 and z ranges from 0.9 to 2. The transition metal carbonitride is produced by mixing (a) a transition metal oxide source of a transition metal in the above formula and (b) a carbon source such as carbon black. This mixture is heated at a rate of between 100 K/sec to 100,000,000 K/sec in a nitrogen containing non-oxidizing gas such a s nitrogen or nitrogen mixed with argon to an elevated temperature that makes carbothermal reduction of the transition metal oxide source thermodynamicall y favorable for a residence time sufficient to convert the transition metal oxide source into at least one product selected from the group consisting of : (i) a transition metal carbonitride and (ii) a transition metal carbonitride precursor. The product may be exposed to a finishing step involving heating the product to a temperature less than the elevated temperature in a finishi ng atmosphere such as nitrogen, hydrogen, inert gas or combinations thereof to form submicrometer carbonitrides of higher purity or different stoichiometry .

Abstract: The invention concerns a method for recuperating ambient thermal energy for an engine or vehicles equipped with pollution-free motors functioning with injection of secondary compressed air in the combustion chamber (2) and having a reservoir for storing highly compressed air (23). The highly compressed air contained in the reservoir is, previous to its being injected into the chamber (2), expanded in a system with variable volume such as a piston-cylinder assembly (54, 55), producing a work which is used by mechanical means or the like. This expansion- to the injecting pressure- with work causes the air to cool to a very low temperature. This air is then propelled into a heat exchanger (41) where it is heated, thus increasing in pressure and/or in volume by recuperating a supply of thermal energy derived from the atmosphere. The invention is applicable to all engines equipped with compressed air injection and to the production of conditioned air in the vehicle.

Abstract: K sub-carrier components from an FFT circuit 101 are output to a sub-carrier demodulating circuit 102. The sub-carrier demodulating circuit 102 demodulates the k sub-carrier components and outputs a transmitted information bit to an output terminal 104. Further, the sub-carrier demodulating circuit 102 outputs distortion correction coefficients C(1) - C(k) that are used during demodulation of each sub-carrier, each of sub-carrier components S(1) -S(k) in which distortion is corrected, and determination signal points R(1) - R(k) for each sub-carrier to a phase estimating circuit 103. The phase estimating circuit 103 receives C(1) - C(k), R(1) - R(k) and S(1) - S(k), and outputs a phase error signal to an output terminal 105.      The phase error signal output to the output terminal 105 is integrated by a loop filter and so forth, and is fed back to a local oscillator, and thereby, phase tracking is conducted.

Abstract: A mounting arrangement for a modular component such as a fuel tank for a vehicle such as a truck and a method of installing same on the vehicle. The method is accomplished via a combination of a set or sets of two brackets and an initial alignment means for each set of brackets. The initial alignment means is comprised of two mating components, with one mating component being a portion of one bracket and the other mating component being a portion of the second bracket. One bracket of each set is installed directly to a portion of the vehicle under manufacture , such as to the frame rail. A modular assembly is assembled separately with the second bracket of each set installed on the modular assembly. The sets of brackets are joined via the initial alignment means attaching the modular assembly to the vehicle. Final attachment may then be made between t he set or sets of two brackets and hence the modular assembly and the vehicle, while the modular assembly is held into proper position via the initial alignment means. This attachment method may be used on a battery box assembly both with and without an attached air tank.

Abstract: The improved spherical plain bearing of the present invention is formed using a unique method of manufacture which includes surface hardening of the outer ring and the inner ring wherein the outer ring includes a fracture zone having a reduced cross-sectional area which allows the case hardening diffusion technique to penetrate much deeper into the ring fracture zone than in the other areas thereof. In this manner the reduced cross-section area of the outer ring provides a more brittle area with less of the more ductile interior steel which is more difficult to fracture. Such fracturing is necessary with such plain spherical bearings in order to allow placement of the inner ring within the outer ring. The spherical plain bearing produced by this method can include a single fracture or double fracture. Thus this bearing provides significant structural strength due to the inner core of softer more ductile steel while at the same time providing enhanced wear characteristics due to the case hardened outer layer on both the inner and outer races.

Abstract: L'invention concerne un procédé d'élimination de composants de gaz acide d'un mélange gazeux. Le procédé consiste à mettre le mélange gazeux en contact avec un solvant ou un réactif liquide de gaz acides dans un premier contacteur à turbulence et à soumettre le mélange de gaz et de liquide à un mélange turbulent. Cette opération entraîne l'absorption du gaz acide par le solvant ou le réactif. Le mélange fluide est passé dans un deuxième contacteur à turbulence et soumis à d'autres mélanges turbulents, ce qui provoque l'absorption d'un autre gaz acide par le solvant ou le réactif. Le mélange fluide est éventuellement séparé en une phase gazeuse et une phase liquide.
