摘要： Generator of physically unclonable cryptographic keys (PUF) has two adjustable speed ring oscillators (GPRS, GPRS′), which outputs (o-GPRS, o-GPRS′) are connected to inputs (i1-DF, i2-DF) of a phase detector (DF), which output (o-DF) is connected to control inputs of the adjustable speed ring oscillators (s-GPRS, s-GPRS′) through a control system (US) and is also connected to a output (o-PUF) of the generator of physically unclonable cryptographic keys (PUF) through a sample and compare circuit (URP). Generator has a initializing input (i-UCH) connected to both initializing inputs of the adjustable speed ring oscillators (i-GPRS, GPRS′) and to the first input of the sample and compare circuit (i-URP), which second input (z-URP) is connected to the output (o-GPRS′) of one of adjustable speed ring oscillators (GPRS′).

摘要： Exemplary arrangements relate to methods for recording and reproducing holograms. A method of recording a hologram in a thresholded opto-magnetic medium (7) includes producing a collimated recording beam (1) with a pulsed laser. The intensity of the recording beam is selectively modulated by passage through a modulator (2). The recording beam is spatially shaped by passage through a shaping element (15). The shaped modulated recording beam is made convergent by passage through an aspheric lens (4). The convergent beam is deflected bidirectionally with a MEMS mirror (6) that is in operative connection with the modulator, such that multiple disposed locations on a surface of the medium are exposed to a constriction of the convergent shaped recording beam, causing a change in the medium in the locations. Reconstructing the hologram is carried out by illuminating the medium with a collimated laser beam and focusing with a lens, light from the illuminated medium onto a detection matrix. Additional methods of recording and reproducing holograms utilize alternative steps.

摘要： The process for the manufacture of chemical resistant polyarylate films and coatings obtained by dissolving the polyarylate in a mixture of typical solvents and forming the same by evaporating said solvents, consists in additionally conditioning the films and coatings at a temperature of 135 320*C for 1 - 10 hours. The conditioning process is applied to polyarylates containing in the main chain a group in which the carbon atom between two aryl rings is connected to a CCl2-group by a double bond.
