Patent DE-4041204-A1 (DE)
Title: Adaptive threshold setting for radar echo measurement window - has windows divided into fields for iterative comparisons of weighted mean and standard deviation of amplitude
Inventor: BOETTCHER REINER DIPL ING
IPC: G01S7/292
Filed: 1990-12-21
Abstract: Within the window an amplitude mean (Mu1 etc.) and standard deviation (sigma) are assigned to each field of 64 or ore radar resoln. cells and stored in programmable read only memories (PROM1,PROM2). One memory (PROM1) produces a squared mean which is used together with the mean square to address the other memory (PROM2) providing the standard deviation. Redn. and target recognition thresholds (RED,ZEK) are compared with linear overall mean and standard deviation values multiplied by estimation factors. USE/ADVANTAGE - Esp. in surveillance of shipping lanes. Misinterpretation of target information is excluded with higher security.

Patent DE-4134082-A1 (DE)
Inventor: KNEER ROLAND
IPC: B65D55/02
Filed: 1991-10-15
Abstract: The stopper (1) contains as a tamper-proof safeguard a frangible securing ring (4) which surrounds the edge of the container mouth. The securing ring (4) is provided with an inwardly facing annular bead (15) which engages below an outer annular projection of the container. The stopper (1) has an olive-shaped boss (6) which engages in the container mouth in the clamping fit and a slide (3) which serves as child-resistant safeguard and can be pushed beyond the edge of the container mouth, when the tamper-proof securing ring (4) has been removed, in order to overcome the clamping fit in the container mouth. In order that the stopper (1) cannot be "levered off" from the container without damaging the securing ring (4), said securing ring (4), in addition to a cylindrical wall section, has a circular wall section (11) which is bent inwards by 90 DEG  and is connected to the top part of the stopper via a circular intended tearing seam (13). A circumferential blocking section (5) of the securing ring (4) has a circular wall section of greater wall thickness which is not connected to the top piece and merges via a film hinge (14) into the cylindrical wall section. In the attachment position of the stopper (1), the freely ending circular wall section is inevitably folded up into the path of movement of the slide (3) so that the latter cannot be pushed forwards. In an attempt to "lever off" the stopper (1), the circular intended tearing seam (13) would inevitably be torn open.
