Patent EP-0151656-A1 (EP)
Inventor: SIARKIEWICZ PIOTR H
IPC: A61B5/0484
Filed: 1984-01-31
Abstract: An averaging method for elimination of periodic stray signals, such as stray signals originating ain an environment (2) comprising a main signal source, which method is employed in a system for measuring evoked responses during an averaging procedure run in an averaging computer (7) which processes a set of signals picked up from an examined subject (10), e.g. a human scalp, by means of electrodes (11) which set of signals is fed through an instrumentat ion amplifier (9) to an averaging computer (7). A counting circuit in the system for measuring evoked responses comprises a sensing circuit (1), a circuit (3) detecting signal half-periods, a counting circuit (5) and a triggering circuit (6), and introduces permanent desynchronization between the frequency 1/T of external stimuli signals, e.g. from a photostimulator (8), and the sweeps of the averaging procedure in the averaging computer (7) both in relation to the frequency 1/T of the periodic stray signals resulting in amplitudes of the stray signals being substantially completely eliminated.

Abstract: Vorliegende Erfindung behandelt organische Titanchelate, die als Chelatbildner nur Acetylaceton und Triethanolamin enthalten. Sie sind in Glycolethern sehr gut löslich, wobei bereits ein geringer Zusatz der Glycolether zu diesen neuen Substanzen die Stabilität von wässrigen Lösungen außerordentlich verbessert. Vorzugsweise werden Lösungen von 50 bis 80% dieser neuen Chelate eingesetzt, aus denen sich stark verdünnte wässrige Lösungen mit außerordentlich hoher Stabilität herstellen lassen. Beispielsweise zeigen 1 bis 5 %ige wässrige Lösungen dieser neuen Titanchelat-Zubereitungen auch nach einer Lagerzeit von mehreren Monaten keine Ausfällungen und Trübungen, so daß sie sehr gut in wässrigen Systemen als Vernetzer eingesetzt werden können.

Abstract: An analog video data signal digitisation and correction system scans a medium to produce video data signals (21, 13a) representing images printed on the medium. Two reference quantities (31, 32) representing analog reference signals produced by scanning a densely printed image and an area of the medium having no printed image are used to establish the maximum and minimum values of a range of possible values for each video data signal. The analog video data signals are compared (24) with this range and a corrected digital value obtained for each data signal depending on its position in the range. In generating the reference quantities each analog reference signal is converted into a digital reference signal dependent on the position of the analog signal in a range of possible values. For each analog reference signal only a portion of the range of possible values is selected in order to increase the accuracy of the corresponding digital reference signal. The number of bits in the digital reference signal is kept low but the accuracy of each digital reference signal remains high. In converting each digital reference signal into an analog reference quantity additional high order bits are added to the digital reference signal so that each analog reference quantity has the same accuracy as its corresponding digital reference signal.

Abstract: A device for measuring the shape of a three-dimensional object comprises a movable arm (1) composed of a plurality of movable arm members (4, 5, 6) and a probe (8) coupled to a forward end of the movable arm by a universal joint. At each of the movable arm members and probe, there is provided an angle-of-rotation encoder for detecting the angle of rotation. In order to measure the shape of the three-dimensional object with a lesser number of measuring times, the probe (8) has a flat surface portion (8a) at its forward end which contacts the object. A calculating section calculates the direction of the flat surface portion of the probe in contact with the object, on the basis of the information from the angle-of-rotation encoders and the known information on dimensions of the movable arm, to thereby determine a tangent plane of the object at a contact point between the flat surface portion and the object, and determines the shape of the object from a plurality of tangent planes at the contact points.

L'élimination des particules comprend des étapes successives d'élimination des contaminants lourds, moyens et petits, chaque étape étant commandée séparément. L'échantillon de pâte est prélevé là où la concentration est la plus forte, et les signaux concernant les contaminants sont appliqués pour actionner les commandes respectives des différentes étapes.
