Title: Method for determining course of object on linear trajectory using selection of range squares
Inventor: BELOV DMITRIJ VLADIMIROVICH
IPC: G01S13/58

Granted: 2021-08-18
Abstract: FIELD: radio location.  
     SUBSTANCE: in the claimed method for determining the course of an object on a linear trajectory using selections of range squares in a radio location system, the range r i  and azimuth β i  of the object are measured and converted into horizontal rectangular coordinates. The estimates of the rate of change of the rectangular coordinates are determined, an unambiguous estimate of the course   is calculated. The estimate of the radial velocity   in the middle of the observation interval is determined by means of optimal weighted summation of a fixed selection of N measured range values r i . A fixed selection of N range square values is formed and the second increment of the range square   is estimated by means of weighted summation. The estimate of the actual velocity of the object   is found. The heading in the middle of the observation interval   and the root mean square error (RMSE) of determination of said angle are then calculated. The azimuth in the middle of the observation interval is estimated by means of weighted summation of the measured azimuth values β i . Two estimates of the course are determined using the values of the azimuth   and heading   estimates. To eliminate ambiguity, an unambiguous estimate of the course   and the obtained two estimates   and   are used, the ambiguity of determination of the course is eliminated by the lesser difference. 
     EFFECT: increased accuracy and eliminated ambiguity of determination of the course of an object on a linear trajectory.

Abstract: Mit all den Verfahren in den bekannten Ausfuehrungsformen ist die Analyse eines Geschwindigkeitsfeldes mit einer lateralen und axialen Aufloesung kleiner 50 Micrometer nicht moeglich. Die Erfindung betrifft ein Verfahren und eine Einrichtung zur beruehrungslosen Messung der Geschwindigkeit des Weges von Teilchen in Fluessigkeits- oder Gasstroemen gegenueber einer Bezugslage, wobei die Teilchen mittels einer Strahlung beleuchtet und die von diesen reflektierte oder gestreute Strahlung ausgewertet wird. Ein besonderer Vorteil der Erfindung besteht darin, dass der Gleichlichtuntergrund soweit wie moeglich reduziert wird, um die Anforderungen an die Dynamik des detektierenden Systems so gering wie moeglich zu halten. Die Erfindung sieht vor, eine spezielle Beleuchtungstechnik mit einem hochaufloesenden bilderzeugenden Verfahren und die Verwendung submikroskopischer stark reflektierender Teilchen zu verwenden. Die Beleuchtungstechnik bewirkt folgendes: Durch raeumliche Filterung werden die Lichtquellenbilder im Messlicht ausgeblendet. Dadurch ist es moeglich, submikroskopische Teilchen kleiner 0,1 Micrometer, die gegebenenfalls als stark streuende Tracer dem Fluid zugegeben werden, darzustellen. Die Bilderzeugung bewirkt folgendes: Durch die Verwendung eines Objektes mit hoher Apertur und entsprechend starker Nachvergroesserung wird die Tiefenschaerfe des Systems stark vermindert. Dadurch kann eine axiale Aufloesung bis zu O,5 Micrometer bei einer minimalen Messflaeche ...U.S.W

Abstract: In order to place a sealing cap, which is to be placed in particular on a filler neck of a gasoline tank, on the neck so as to preserve the seal with little actuation force but so that it seals securely, the sealing cap is equipped with a turning lifting apparatus (24, 43) which effects a pressing of the sealing ring (4) at the free neck end (5) when the turning stop (26) of the sealing cap encounters the counter stop (27) of the filler neck (1). A pressing member (23) is displaced in the axial direction against the resistence of a compression spring (25) in the turning stop (26) via the turning lifting apparatus and simultaneously moves a radial outer collar which is coupled with the turning handle (2) in the displacement direction and which is contacted by the sealing ring (4) against the free neck end (5), whereby the sealing ring is pressed together. By means of an indicator window (54) one can read off the fully closed position of the sealing cap with certainty. An interior pressure which is too high or a vacuum can be prevented by means of pressure and vacuum relief valves.
