Abstract: A method for manufacturing composite electroceramics comprises obtaining recycled capacitors, coils, resistors, conductors circuit boards, and/or other recycled electronic components. The components may be grinded into a particles having a particle size below 2 mm, and mixed with NaCl powder or Li2MoO4 or other watersoluble ceramic powder having a particle size of 5-200 microns, in a ratio of 10-40 vol-% optionally grinded components, and 60-90 vol-% NaCl powder or Li2MoO4 or other ceramic powder. The obtained solids mixture is mixed with aqueous solution of NaCl, Li2MoO4 or said other ceramic, in a ratio of 70-90 wt-% solids mixture, and 10-30 wt-% aqueous solution. The obtained homogeneous mass is compressed in a mould for 2-10 min, in room temperature, in a pressure of 100-400 MPa. The compressed mass is removed from the mould, thereby obtaining electroceramic composite material. Alternatively to the use of the water soluble salt an organometallic precursor compound can be used.

Abstract: An optical apparatus comprises an ultraviolet light source (100) configured to transmit the ultraviolet light to a sample (102), one or more wavelength dependent beam splitters (104) and at least two separate detectors (106, 108). Each beam splitter (104) receives, from the sample (102), a band of excitating ultraviolet light and at least one band of fluorescence associated with an interaction between the excitating ultraviolet light and the sample (102) in the optical path through the sample (102), directs the band of excitating ultraviolet light passed through the sample (102) towards a first detector (106), and directs the at least one band of the fluorescence towards at least one separate detector (108). The first detector (106) and the at least one separate detector (108) are simultaneously configured to form electrical signals carrying information on powers of the bands of the ultraviolet light and the fluorescence, respectively.

Abstract: The invention relates to a system and a method for optical measurement of a target, wherein the target is illuminated, either actively illuminated, reflecting ambient light, or self illuminating, and a measurement radiation beam received from the target or through it is detected. The measurement system has optical fibers for guiding radiation from/to target positions. Radiation of several target positions is simultaneously filtered by a Fabry-Perot interferometer and detected by a row detector, for example.
