摘要:
The present invention discloses a system and method for adaptive adjustment of bit budget that favors the allocation of bits to intra coding frames (I frames). Namely, an encoder is able to dynamically adjust the bit budget for each picture type in an image sequence, thereby effecting proper usage of the available transmission bandwidth and improving the picture quality. In one embodiment, the present invention will allocate more encoding bandwidth to a current Intra coding frame when the average quantization level of inter coding frames (e.g., P and B frames) of a previous group of pictures is relatively high.

A method (50) and apparatus (40) for reducing noise in a video signal calculates (53) a discrimination value of a filter based on a magnitude difference between a current frame and a prior frame of a sequence of frames and modifies (54) the current frame using the modified discrimination value. The output of the filter is calculated as follows: g(i, j, k)=f(i, j, k)±βwherein: f (i, j, k) is the current frame input to the filter; g(i, j, k) is the current frame output from the filter; and β is the discrimination value of the filter, which is calculated as follows: β = { κδ ′ + χ , δ ′ = max { δ , δ 0 } , δ

Insoluble, denatured, heat-stable protein particles are used in food and beverage products. The particles are easily dispersible in aqueous solutions and take the form of substantially non-aggregated macro-colloids. In a hydrated state the preferred mean diameter particle size distribution of the insoluble, denatured, heat-stable particles ranges from about 0.1 microns to about 3.0 microns, with less than about 5 percent of the total number of particles exceeding about 3.0 microns in diameter. The majority of the particles are substantially spheroidal in shape and have a substantially smooth, emulsion-like organoleptic character similar to that of high-calorie fats and oils. Additionally, these particles have a degree of protein insolubility of at least about 80%, which provides processing advantages during heat treatment.

A method for thermal driven placement begins by first computing thermal response functions for individual components for several locations on a placement surface as a preprocessing step to placement. The thermal response functions can then be used to compute junction temperatures of components quickly and accurately during placement of the components in a layout. For a given component location, the component's junction temperature is computed by summing the contributions of neighboring components with the component's own contribution. The difference between predefined junction temperatures for the components and the calculated junction temperatures can then be used to assess the merits of the placement.

A method is provided for compensating an output signal of an electronic device having an input end electrically connected to a feedback device and an output end electrically connected to a load. This method includes steps of (a) measuring a standard voltage V.sub.o of the load, (b) determining an input voltage V.sub.i and an input current I.sub.i of the electronic device, and (c) generating a feedback signal based on said input voltage V.sub.i. The method further includes steps of (d) determining a maximum current I.sub.max and a minimum current I.sub.min of the feedback signal passing through the feedback device, (e) defining an estimated output current I.sub.o of the electronic device based on the maximum current I.sub.max and the minimum current I.sub.min, and (f) compensating the output signal of the electronic device according to a compensating factor d determined by the standard voltage V.sub.o, the input voltage V.sub.i, the input current I.sub.i, and the estimated output current I.sub.o, of the electronic device. The estimated output current I.sub.o is calculated according to the maximum current I.sub.max and the minimum current I.sub.min by a first equation of I.sub.o =I.sub.max +kI.sub.min where k is a constant.
摘要:
Chocolate flavored nut spreads, especially chocolate flavored peanut butters having a milk chocolate like flavor without a bitter aftertaste and with desirable spreadability. Cocoa solids substantially free of dairy solids that are encapsulated by sugar are dispersed substantially homogeneously throughout the spread. The level of cocoa butter is also below the point where it can crystallize out (i.e., typically about 20% or less on a total fat basis).

It is related to a method for preparing polyoxymethylene dimethyl ethers by a continuous acetalation reaction of trioxymethylene and methanol or methylal catalyzed by an ionic liquid. The processing apparatus used in the method includes a reaction zone, a separation zone, a catalyst regeneration zone and a product dehydration zone. A manner of circulating tubular reaction is used, resulting in a high external heat exchange efficiency, a simple structure of design and a low investment. A film evaporator is used, realizing a rapid separation and recycling of the light component, with a high separation efficiency. The separation of the catalyst solution from the crude product is simple, thereby realizing the regeneration and recycling of the catalyst.
