Abstract: Изобретение относится к средствам развёртывания тросовой системы, включающей в себя связанные космические аппараты (КА). На одном из КА (2) установлен барабан (3) с тросом (4), безынерционная (5) и электромагнитная (10), с регулируемым источником питания (11), катушки. На другом КА (8) закреплён (7) свободный конец троса (4) и предусмотрен стыковочный адаптер (12) для КА (2). КА (8) снабжён сверхпроводящей (С-П) катушкой (13), закорачиваемой с помощью С-П ключа (14). Когда КА (2, 8) состыкованы, ток в С-П катушке (13) равен нулю, а катушка (10) запитывается от источника (11). В результате взаимодействия полей данных катушек КА (2, 8) отталкиваются друг от друга и, при освобождении от взаимной фиксации, расходятся до расстояния, равного длине троса (4). В этом состоянии тросовой системы ток в С-П катушке (13) равен нулю, и это состояние в дальнейшем автоматически стабилизируется по известному свойству С-П контура. Технический результат состоит в повышении надежности и гибкости управления развёртыванием тросовой системы. 1 ил.

Abstract: FIELD: information security.  
     SUBSTANCE: invention relates to the field of information security. The selected container is divided into square areas of pixels of a certain size, and the size of the square area of pixels is selected based on the hiding detail. Each subsequent square area of pixels is obtained by shifting the previous square area of pixels to the right by one pixel, and when the border of the image width is reached, the next square area is formed from the beginning of the next line. Next, new square zones are formed by shifting the previous square zone by one pixel until the border of the image width is reached, after which the actions are repeated, while the displacements are performed until the pixels in the selected container are completely enumerated. Then the value of pixels in the square area of pixels is calculated, in each square area of pixels a linear transformation of the elements is performed. The modulus of the determinant of each square area of pixels is determined. The obtained values of the moduli of the determinants of the square areas of pixels are ranked. The information is embedded in the bits of only one pixel of all three color components in a square area of pixels.

Abstract: FIELD: testing. 
     SUBSTANCE: proposed are a method and a system for detecting nickel sulphide-based inclusions in sodium-calcium-silicate glass such as thermally polished glass. During and/or after the glass manufacturing process, after a stage in the float process wherein a glass sheet is produced and placed on a molten material (e.g., in a bath with a tin melt) and cooled or left to cool, e.g., using an annealing lehr, light is directed at the resulting glass, and the wavelengths of reflected light (e.g., the wavelengths of red and blue light) are analysed in order to detect inclusions. The fact whether inclusions are present in the glass is determined on the difference between how the first and second wavelengths of reflected light are diffracted and/or scattered.
