A user interface for a touch-screen display of a dedicated handheld electronic book reader device is described. Measures, such as adjusting the throttle valve, a varying inlet and exhaust valve timings, operating a secondary-air pump, ensures that the internal combustion engine, when running down, scavenges exhaust gases from the cylinder by providing fresh air into the. In the method, a sample is moved electrokinetically into the electrolyte channel, to form a defined sample volume therein. The optimized contribution signal is generated by retaining only the global broadcasting services that are different from one another. The electronic reading device stores the grid description and uses it to identify positions corresponding to successively detected portions of the address pattern, to determine whether the positions are within the current grid description, to generate strokes from the positions, and to initiate actions based on the generated strokes. High-speed fault detection of circuits in power distribution networks uses protective relay devices segmenting a distribution line having Intelligent Electronic Devices associated with switching devices communicating peer-to-peer via a communication system to provide fast and accurate fault location information in distribution systems with sequential logic.
