The Microelectronic Radiomeasuring Transducers of Magnetic Field with a Frequency Output

Abstract

In the given article the integrated circuits of transducers of a magnetic field in which magnetic sensitive transistors act in a role of active elements of autogenerating arrangements of transducers that simplifies circuits of sensor controls of a magnetic field are offered. It is shown, that for the complete embodying transducers in an integrated view the passive tuned-circuit inductance of the arrangement is implemented as the reactive transistor. The greatest sensitivity which changes from 7,2 kHz/mT up to 6,3 kHz/mT , the circuit design about a magnet a sensing element has on the basis of two collector bipolar transistors with the active inductive element.

Study of the dynamic stability of the belt conveyor adaptive drive

“…The above-mentioned methods of stability study are rather complicated and labour consuming for studying higher than quantic systems [30,31,32].…”

Tool Control the Concentration of Carbon Dioxide in the Flue Gas Boilers Based on the Optical Absorption Method

“…As shown on Fig. 2, the absorption spectrum of carbon dioxide in the given range has a complex structure due to overlap of the spectra of gases that are part of its composition, so the absorption coefficient k(λ) of the band is expressed by the sum of the absorption coefficients of the individual lines [12,13] ,…”

Experimental research of turbo-codes application in telemedicine systems with wireless body area sensor networks

“…So, the results of these experiments are shown high efficiency of the turbo-code. The PL-log-MAP algorithm is shown to have very good performance to use it as a main algorithm for turbo-decoder in WBAN communication unit [41][42][43].…”
