Granted: 2020-08-21
Abstract: FIELD: measuring equipment.SUBSTANCE: invention relates to measurement equipment and can be used for accurate measurement of small linear velocities of object displacement, as well as for evaluation of speed deviation from preset value. Proposed method of linear velocity measurement and control of its non-uniformity involves three stages: 1) setting the required constant speed of the object along the straight line, measuring the coordinates of the object at equal time intervals specified by the microcontroller, calculating values of instantaneous speed Vfor each specified time interval, averaging obtained values of instantaneous speeds V, using method of sliding window, wherein the value of the window is selected experimentally, obtaining the averaged values of the instantaneous velocities V(t) and using these values V(t), calculating the velocity deviation on the required sections of the object movement path to estimate the non-uniformity of the measured linear velocity; 2) by means of Fourier transformation obtaining frequency spectrum of changes of instantaneous speed Vand analyzing it, then possible elimination of sources and causes of occurrence of non-uniformity of measured linear velocity; 3) repeating the actions performed at the first step, and additionally comparing the newly calculated speed deviation value with the previous one, if necessary repeating the second and third stages.EFFECT: disclosed method enables to measure the object linear velocity and determine the degree of its non-uniformity.1 cl, 4 dwg

Abstract: Изобретение относится к области медицины, а именно к стоматологии, и может быть применено для предупреждения возникновения гальваноза полости рта. Определяют наличие в полости рта конструкций из разнородных металлов, и если такие конструкции есть, то назначают 1 балл, а если нет - 0 баллов; если присутствует отягощенный аллергический анамнез, то ставят 1 балл, если его нет - 0 баллов; если имеет место наличие заболеваний желудочно-кишечного тракта, например хронического гастрита, язвенной болезни желудка и двенадцатиперстной кишки, то ставят 0,5 балла, а если нет наличия таких заболеваний - 0 баллов; определяют показатель иммуноглобулина Е сыворотки крови, и если он представляет собой величину от 70 до 100 МЕ/мл, то ставят 2 балла, а если больше или меньше этого диапазона ставят 0 баллов; затем подсчитывают сумму баллов и при сумме 0-1 балл делают вывод, что вероятность возникновения гальваноза полости рта почти невозможна (2,15%); при сумме 1-2 балла - низкая степень вероятности возникновения гальваноза полости рта (48,32%); при сумме >2 баллов - высокая степень вероятности возникновения гальваноза полости рта (95,9%) - не следует протезировать пациентов с такими показателями металлическими конструкциями.

The first end of the first handle constitutes a gripping section, the second end of the first handle is rotatably connected to the first end of the second handle. When the second handle rotates in the first direction, the second end of the second handle pushes the staple-pushing rod of the stapler to trigger operation of the surgical stapler. The surgical stapler comprises the described handle assembly. 
     EFFECT: inventions are characterised by the fact that the first handle can be pressed by the doctor for moving regardless of whether the stapler is ready to operate or not, while the stapler cannot be triggered to operate by a through movement of the first handle through the second handle when the stapler is not ready for operation, and to prevent cracking of the body due to vigorous handle pressing.
