Article
Full-text available
LaFeCoSi alloys have attracted much attention as they exhibit magnetocaloric effect in near room temperature. The paper focuses on the description of anhysteretic curve for LaFeCoSi alloy for temperatures close to transition point. For this purpose the Langevin function is applied. The paper confirms that the Langevin function might be a good start...
Article
Purpose The purpose of this paper is to develop identification system for fiber optic connectors in passive distribution cabinets. The system should have alternative power supply and wireless communication unlike the identification systems commercially available, which will make the system fully autonomous. Design/methodology/approach Detailed p...
Article
Full-text available
Fiber Distribution Cabinets (FDC) monitoring systems are increasingly popular. However it is difficult to realize such system in passive FDC, due to lack of source of power supply. In this paper investigation of four different DC power supplies with optoelectronic transducers is described. Two converters: photovoltaic power converter and PIN photod...
Article
Full-text available
A huge progress of down-sizing technology together with trend of decreasing power consumption and, on the other hand, increasing efficiency of electronics give the opportunity to design and to implement the energy harvesters as main power sources. This paper refers to the energy that can be harvested from electromagnetic field in the unlicensed fre...
Article
Full-text available
The paper included fabrication and characterization of the bulk heterojunction organic solar cell (BHJ OSC) based on poly[(9,9-di-noctylfluorenyl-2,7-diyl)-alt-(benzo[2,1,3]thiadiazol-4,8-diyl)] (F8BT) and fullerene derivative [6,6]-phenyl-C61-butyric acid methyl ester (C60PCBM). It was studied the influence of annealing the temperature range: 120°...
Article
Full-text available
The paper presents magnetic parameters of LaFexCoySi1:1 bulk specimens proving strong magnetocaloric effect. The main research work was oriented on measurements of the alloy's power losses according to IEC 60404 standards and validated with unbalanced bridge method and other methods. The measurements of the LaFe10.8Co1.1Si1.1 specimens were determi...

In this paper detailed efficiency analysis of three different DC power supplies with optoelectronic transducers is described. We have demonstrated that it is possible to build monitoring system in passive Fiber Distribution Cabinets.
Conference Paper
Full-text available
Announced paper refers to energy harvested from electromagnetic field in the unlicensed frequency bands. The paper constains description of the most popular techniques and transducers that can be applied in energy harvesting domain. The overview of current research and commercial solutions was performed for bands in ultra high frequency range which...
