Image sensors based on the CMOS technology became commonly used sources of image information in PC-based vision systems. Image information is converted directly on the chip to a stream of synchronous digital data which can be transferred to a PC using the cost-effective interface introduced in this contribution. The CMOS image sensor together with the developed interface can be considered as a simple image acquisition system - USB camera matching all features of distributed image acquisition and processing model described in this article. Concept of the USB camera is enhanced by additional data merged with each image frame transferred to the PC. This feature makes the developed device suitable for tasks where the precise timing of image acquisition together with an external synchronization is required. Based on the VHDL model of the used CMOS image sensor and the designed PC interface with the USB driver, the critical timing and maximal USB data throughput limitations are analyzed and discussed.

The paper examines the options for replacing the current energy mix of non-renewable, conventional energy sources solely with renewable sources in the long term within the context of the Slovak environment, possibly combined with nuclear energy in the 50-year horizon. Vital needs are outlined in household energy consumption and energy consumption for industrial and transportation purposes to fulfil in order for Slovakia to become independent of foreign sources in energy supplies.

The paper describes functions and legal obligations of Electricity market operator. One section of this article describes history of Slovak EMO establishment and its operation if first few months of existence. In further text shows curse of electricity price and quantities of traded electricity by Day-Ahead Market Organizer in past few months. In future development of liberalized electricity market is expected to EMO take over some new features from Transmission System Operator, so the last section is devoted to possible developments of electricity market in the future.
