Patent EP-0375301-A1 (EP)
Inventor: BOHMAN CARL E
IPC: A01D75/00
Filed: 1989-12-15
Abstract: A non-contact row crop sensor comprises one or more transmitter/receptor pairs (24, 26; 34, 36) mounted on two row separators (10, 12) of a harvesting machine. Each transmitter (24, 26) transmits an energy beam (40, 42) to one of the receptors (34, 36) and the energy beams  (40, 42) cross at a point which defines a position of the harvest­ing machine relative to a row of crop stalks (18). A circuit (50-58) produces steering control signals dependent upon the time of intercept of one beam (40, 42) of a pair relative to the time of intercept of the second beam (40, 42) of the pair. A discriminator circuit (170, 172 - Figure 6) may be provided for discriminating between crop stalks (18) and weeds. Plural transmitter/receptor pairs (24U, 24L, 26U, 26L; 34U, 34L, 36U, 36L) permit discrimination between intercepts caused by leaves and those caused by stalks (18). When a single pair of transmitter/receptors (24, 26; 34, 36) are employed the transmitters (24, 26) may be infra-­red transmitters.

Title: Procedure and device for testing the fluid tightness of a container
Inventor: DELEUZE GILLES
IPC: G01M3/10
Filed: 1990-10-01
Abstract: The invention relates to a procedure and device permitting testing of the fluid tightness of the container (9) by placing the latter in a bath of liquid (2) under a funnel (3) which is connected to a capillary tube (4) in which the liquid (2) is made to circulate. Sensors (50, 51, 52) detect the passage of gas bubbles escaping from the container and this, by measuring the velocity of the bubbles, enables the volume of each bubble to be measured. An advantage of the invention is that the volume of the bubbles is not obtained by a measurement of volume but by detecting the times at which the bubbles pass. The measurement is therefore more accurate. Application to testing the fluid tightness of containers for components, particularly electronic components. <IMAGE>

Abstract: Dans la présente invention, on considère que la représentation d'un caratère ou d'un symbole comprend un ensemble de zones formées horizontalement et verticalement. Lesdites zones sont totalement spécifiques des caractères. Chaque zone définit l'étendue d'une certaine caractéristique du caractère. Les limites des zones sont topographiées en des adresses de pixels spécifiques sur un carré graphique ayant une définition et d'une taille sélectionnées. Des zones d'interpolation supplémentaires sont définies, qu'on utilise pour topographier tous les points de la représentation du caractère contenus dans la zone d'interpolation mais qui ne coïncident pas avec un bord de cotrôle, en partant depuis des positions dans le carré em à haute définition jusqu'à des positions correspondants dans le carré em à faible définition. Pour maintenir des relations entre les caractéristiques on peut définir des fonctions de contrainte qui règlent la taille des zones de contrôle d'un caractère à des tailles prédéterminées. Les zones de contrôle et les zones d'interpolation sont reliées par dérivation à un ensemble de base de bords de contrôle horizontaux et verticaux au niveau de la description du contour. En conséquence, on réduit le nombre de calculs requis et on augmente la vitesse à laquelle on peut générer un graphique en points à partir de la représentation de contours.
