This article deals with automatic testing of multimedia units. The aim of the work was to design and implement an automatic test system for a functional parameter measurement of multimedia units. The system was built up with the help of individual measuring devices and the...

This article describes how to use common IT components to create interactive devices for children with learning disabilities. In this case the cheap touch monitor was used. The first part of this article shortly describes the main idea of this project. Next part talks about&#x...

A novel approach to designing antenna systems for television receivers is proposed. The antenna system is embedded into the receiver to make the television receiver partly independent on the roof antenna system. For this purpose, it employs diversity techniques to cope with lower p...

This article presents control architecture of industrial robot Mitsubishi RV-2SDB that is integrated into Flexible Manufacturing Company. The robot handle head is equipped with air vacuum suction cups, by which the robot handles with the products. The robot is part of the Flexible ...

This paper deals with measurement and computer simulation of varistors tests, that are used like surge protectors. At the beginning basic characteristics parameters of varistors are described. The next section of paper introduces surge protectors standards. According to these standards measuremen...

The paper outlines the structure of the advanced distributed control node and describes its implementation example on the STR912 ARM platform. The node features two communication interfaces - CAN (Controller Area Network) and Ethernet, equipped with high-layer protocols MicroCANopen and HTTP ...

The highly competitive market of TV receivers brings the implementation of new functions as a must. This has to be carried out without a significant increase in price for the end consumer. The present introduction of digital broadcasting systems offers a possibility of antenna-syst...

In this paper, there is a possibility of nonlinear dynamic systems control described. A synchronisation of two coupled chaotic oscillators based on the state reconstruction is presented. As an example the well known Lorenz system was chosen and the same method of synchronisation wa...

Problems with evaluation of phase relations of reverse tractive current produced by railway driving vehicles are described in this article. This evaluation is newly required in innovated standard ČSN 34 2613. The possibilities and problems of phase analysis

Accuracy of blood pressure (BP) measurement with any method is affected by cuff size. Narrow cuff overestimates BP and wide cuff underestimates BP. Wrist cuff oscillometric BP monitors typically use narrow cuffs with bladders about 6 cm wide. The segment of the radial artery c...

In this paper three different mechanisms of nonlinear and chaotic oscillation occurrence are studied. The first model comes from antisymmetric system structure and oscillations are caused by impossibility to reach the equilibrium state or to diverge to infinity. The second case studies ...

The increasing network traffic often causes various problems depending on different communication requirements in ZigBee. In particular, in a one-to-one communication environment, there exists a data loss problem as the network traffic increases, while in a many-to-one environment, there exists a...
