Emisní testy nezávislého systému pro redukci NOx

The paper describes the method of emissions measuring changes. The new WLTP method is shortly introduced, included WLTC and RDE. Next, the real driving tests results of the independent SCR system are discussed.

Valenta, Pavel
Piezoelektrický transformátor jako zdroj napětí pro Geiger-Müllerův detektor

Radiation detectors such as Geiger-Müller tubes need a high-voltage power supply for operation. The supply voltage can be in the range from 100 V to 1000 V. Piezoelectric transformers are able to generate desired voltage. In this article the possibilities of utilizing Rosen type&#x...

Elektronické vybavení umožňující řízení aktivní regenerace ERDPF filtru

The paper describes one key function of the ERDPF electronic control system. The main function of electronic system is the switching of regeneration current loops. For this reason, the electronic system has to be equipped by a reliable and quick control MOSFET driver. This dri...

Dudáček, Luděk
PilsenCUBE-Strato – Stratosferic Test of the Sensors for PilsenCUBE-II Satellite

Small satellites are nowadays at least often equipped by large number of sensors for attitude determination. Due to small budget, which is quite often in small satellite project, it is necessary to use cheap sensors, that are not designed for space applications. There is no&#x...

Model vytížení přijímače ADS-B na nízkých oběžných drahách

Automatic Dependant Surveillance - Broadcast (ADS-B) is system used for plane localization and tracking in order to air traffic management (ATM). Aircraft equipped by the ADS-B periodically transmits flight related information in the form of Mode-S 1090ES data signal. ADS-B mess...

Lufinka, Ondřej
Ultrazvukový vysílač a přijímač s možností datové komunikace a měření vzdálenosti více bodů

This paper deals with the problem of the short distance measurement between two (or more) moving points with the ability of a simple data communication. Different possibilities were explored and using the ultrasonic transceiver was then chosen for a future development. The article ...

Paločko, Lukáš
Spektrum sigma-delta modulace

The objective of this paper was describe spectrum of the sigma delta modulation and their normalization to the Power Spectral Density (PSD) .

A wrist cuff method for acquisition and analysis of radial artery waveforms used for blood pressure measuring

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...
