A process for operating an internal combustion engine with a charging device such as a turbocharger and with an intake valve drive mechanism which is variable with respect to its intake valve control times and / or its intake valve stroke. Upon recognition of a positive charge requirement during the operation of the charging device, the at least one variable intake valve drive mechanism is driven in such a manner that an available stroke reserve and / or intake closure control time reserve is utilized to increase the charge amount introduced into an engine cylinder.

Method for scheduling and implementing an electronic meeting conducted among remotely-located users communicating with an agenda server, including: accepting a meeting agenda that includes a plurality of topics, a quorum, an identification of resources used by each topic, an identification of data used by each topic, and an identification of data produced by each topic; partitioning the meeting agenda into at least a first and second group of topics; searching for data dependencies between the first and second groups of topics; searching for resource dependencies between the first and second groups of topics; if data dependencies or resource dependencies are found between the first and second groups of topics, then repartitioning the meeting agenda until the data dependencies and resource dependencies between the first and second groups of topics are reduced below a predetermined dependency threshold; and concurrently scheduling and executing the first and second groups of topics.

The invention puts forwards a scheme for FPGA clock network design for a programmable logic device. In order to meet the requirement for timing sequences by obtaining smaller clock skew, a design scheme for netted trees is adopted for the clock network. Clock burrs can be eliminated by filtration due to a push-pull structure added to a leaf unit. Noise interference caused by coupling and parasitic effect is eliminated so that stable waves are generated. In addition, configurable design is carried out on the clock network and is compatible to ordinary programmable devices.

The invention discloses a hardware encoding and decoding method built in an MCU for realizing industrial bus communication. The method comprises an encoding and decoding module built in an MCU. The encoding and decoding module is composed of a decoding module and a code transmitting module, wherein the decoding module is used for measuring pulse widths among a plurality of events, analyzing the pulse widths into digital signals and storing the digital signals in a decoded data register of the MCU; the code transmitting module is used for modulating the digital signals into corresponding pulsewidth data, storing the pulse width data in the code transmitting data register of the MCU, and transmitting the pulse width data in the form of high-low level. A self-designed decoding mode and a self-designed code transmitting mode are adopted to realize encoding and decoding of industrial bus pulse signals. In this way, the method fundamentally solves the technical problems existing in conventional modes, can ensure the timing of bus communication, can reduce development difficulties and costs, is high in encoding and decoding accuracy, and ensures the stability, consistency and signal transmission distance of the system as a whole. Therefore, the method is suitable for popularization and application.
