Opis:: Surface Acoustic Wave (SAW) devices are used in variety of sensing application. This paper describes the sensors operated with shear horizontal (SH) mode wave, in liquid. Liquid sensors of conductivity and viscosity are described and results of modelling of their properties are given. Parameters of SH mode sensors design are also given.

Opis:: Most surface wave filters use interdigital transducers on piezoelectric substates to produce chirp filters. Alternate type of filter use controlled reflection of surface waves from surface gratings. The second type (RAC - Reflective Array Compressor) are free of spurious signal and second order effects, and in large time-bandwith application are better than filter based on interdigital transduces. Designing method, technology and practical results of RAC filter with two 90 degree reflections are presented.

Opis:: In this paper, the degree of contamination of water was determined from anthropogenic reservoirs, located in the area of former coal mine Rozbark in Bytom. The physicochemical analysis of water indicated a high degree of anthropopression. In all analyzed reservoirs, permissible concentrations of chlorides and sulphates were exceeded. In the majority of them, the values of electrical conductivity and total suspended solids were also exceeded. In order to determine the transformation of surface water contamination, there was a comparison of archival data of water quality and laboratory tests performed after five years. Comparative analysis shows that in the last five years, there has been no improvement in the quality of the analyzed surface waters. In fact deterioration of the quality was noticeable.
