Latency compensation is performed during play of a multiplayer video game over a network. A first system includes a first estimator, a first player, and a first game object controlled by movement of the first player, and a second system includes at least a second player and a second game object controlled by movement of the second player. The first estimator receives data values characterizing delayed states of the second system via the network. Based on the received data values, the first estimator estimates a latency-compensated state of the second game object using a physics model of the second game object and a behavior model of the second player. The behavior model provides a representation of how the second player interacts with the video game relative to the first player. The first player is enabled to interact with the video game with compensated latency.

Events that occur in a number of in domain communication channels where each channel is used by a communication service, are detected. A Bayesian Belief Network (BBN) defines a probabilistic cause-effect relationship between each cause and each effect on a victim channel. The probability of each of a number of possible causes as being a cause of interference in the victim channel is determined, by propagating observations of the interference backwards through the BBN.

A system and method is given for minimizing periodic disturbances in electronic systems. Given the input-output characteristics of the system, the present method identifies and cancels the periodic disturbance. The periodic disturbance parameters are identified through the use of a residual generator. The output of the residual generator is fed into an identifier that estimates disturbance parameters. The compensation filter combines the output of the identifier with a set of pre-computed parameters to form a cancellation signal. This signal is then added to the input of the plant to cancel the periodic disturbance.

A heat treatment apparatus for making a heat treatment while estimating temperatures of objects-to-be-processed that can estimate correct temperatures of the objects-to-be-processed. A reaction tube includes heaters and temperature sensors, and receives a wafer boat. A controller estimates temperatures of wafers and temperatures of the temperature sensors in zones in the reaction tube corresponding to the heaters by using the temperature sensors and electric powers of the heaters. Based on relationships between estimated temperatures of the temperature sensors and really metered temperatures, functions expressing the relationships between the estimated temperatures and the really metered temperatures are given for the respective zones. The functions are substituted by the estimated wafer temperatures to correct the estimated wafer temperatures. Electric powers to be fed to the respective heaters are respectively controlled so that the corrected wafer temperatures are converged to target temperature trajectories.

Batch-type heat treatment apparatus and control method for the batch-type heat treatment apparatus

A method for designing high performance products incorporating signal processing and feedback control is disclosed. In one embodiment, a block diagram may be used for a design cycle, for design optimization, or for design estimation. The block diagram contains a set of differential equations or difference equations, and the solution of these sets of equations may be performed by commercially available software tools. In order to utilize the software tools without requiring access to source code or other descriptions of the internal structure of the tools, the system is decomposed using the technique of waveform relaxation. The decomposition using waveform relaxation operates directly to speed up the computations for the block diagram system. The remaining interprocessor communications may be held pending until the end of each iteration's calculations in each block, allowing the software tools to be executed on independent multiple processors. Additional low fidelity models may be added to the block diagram to accelerate the convergence. In non-stationary methods, the model representing each block may vary with each successive iteration. The variation may take the form of successively increasing the complexity and therefore the fidelity of each block with each successive iteration, starting with low fidelity models and finishing with high fidelity models.
