Railway axle counters are used to control occupancy of railway sections. Their typical application is occupancy control of level crossing or open railroad sections within the automatic block system. This paper presents possible architecture of railway axle counter using microcontrollers that fulfill SIL 3 safety level defined by IEC 61508 Standard.
Increases in speed and capacity, and decreases in area size and power consumption of computer memories are key guidelines in DRAM technology development. Another important requirement is improvement of memory-memory controler interface. Due to the increase in clock frequency, it is necessary to pay attention to the signal integrity. Successful interface design requires a large number of simulations...
Video Wall systems are usualy implemented by using industrial PC systems with multiple graphic cards. In this paper we present different concept of these systems that is based on separation of the units for video generation from the server for processing multimedia information. Unit for generation of video signal — highly reliable Ethernet client with multiple video outputs is presented in detail.
Wireless sensor networks are used for monitoring phenomena using spatially distributed sensor nodes. A wireless sensor network may be far away from a server which collects and processes data from the network. In that case, one or more gateways are used to connect the network to the remote server via TCP/IP or UDP/IP. To speed up testing and deployment of a network, we have developed a simulator which...
