In chemistry, and in physics, a dynamic equilibrium exists once a reversible reaction occurs. The ratio of reactants/products changes, but substances move between the chemicals at an equal rate, meaning there is no net change. Reactants and products are formed at such a rate that the concentration of neither changes. It is a particular example of a system in a steady state. In thermodynamics, a closed system is in thermodynamic equilibrium when reactions occur at such rates that the composition of the mixture does not change with time. Reactions do in fact occur, sometimes vigorously, but to such an extent that changes in composition cannot be observed. Equilibrium constants can be expressed in terms of the rate constants for elementary reactions.
Smart grid price response service for dynamically balancing energy supply and demand
InactiveUS20100138363A1Energy consumptionReduce energy useLevel controlSpecial tariff metersProbit modelSmart grid
A “Smart Grid Pricer” enables automated balancing of the supply and demand of energy supply and consumption, such as the generation and consumption of electricity between electricity providers and electricity consumers. The Smart Grid Pricer automatically computes and delivers real-time energy pricing information to consumers on behalf of energy retailers (e.g., electricity utilities) to help drive the balance of demand with supply. In various embodiments, real-time pricing is determined by using various probabilistic models to estimate overall consumer demand as a function of factors such as energy price, time of day, region, weather, etc. to compute a price that will result in an energy demand that is closely balanced to the available supply. On the consumer side, various components of the Smart Grid Pricer automatically respond to such pricing information to optimize energy consumption in accordance with a variety of automated and / or user defined rules and preferences.

InactiveUS6191800B1Cathode-ray tube indicatorsElectric digital data processingGraphicsComputerized system
A method of generating graphic images on a display device of a computer system, by dividing the viewable area of the display device into a plurality of tiles, assigning each of the tiles to respective rendering processes, rendering a frame on the display device using the rendering processes, and adjusting the sizes of the tiles in response to the rendering step. The method then uses the adjusted tile sizes to render the next frame. The tile areas are preferably constrained from becoming too small. The adjusted tile sizes may optionally be smoothed, such as by averaging in weighted sizes from previous frames. The tile sizes are adjusted by measuring the rendering times required for each rendering process to complete a respective portion of the frame, and then resizing the tiles based on the measured rendering times.
