Abstract: The method for managing a set (100) of communicating objects (101), which are distributed such that each object (101) in the set (100) is neighboring at least one other object (101) in said set (100) so as to form a pair of neighboring objects that are capable of communicating with one another, has the following steps: activation (E1) of an initial object (101a) chosen among the objects (101) in the set (100); propagation (E2), from the activated initial object (101a), of a signal to each of the other objects in the set, said propagation being configured such that each of said other objects in the set has received, at the end of the step of propagation (E2), said signal from at least one neighboring object belonging to said set at least once.

Abstract: A generator of repetitive sets of spreading sequences includes an element for counting and for forming an address and a table containing L sets of S sequences. The address contains q+log2S bits. The q bits are used for selecting one set among L (L=2q) sets. The log2S bits are used for selecting one sequence among the S sequences in the set.

Abstract: The measurement method of the displacement speed of a moving element with respect to a fixed element is performed by means of an optic measuring device comprising a first reference sensor and a plurality of distinct second measurement sensors substantially aligned along the axis of movement of the moving element. The measurement method comprises determination of estimated speeds by correlation of the signals supplied by the reference sensor and each of the measurement sensors, and calculation of a mean speed of said estimated speeds.

Abstract: A process for synthesizing a reference image of an object by applying real image characteristic element data to characteristic elements of a descriptive (CAD based generated) image. The process includes preprocessing the descriptive image data by identifying characteristic elements of the object in the descriptive dam and determining the coordinates of the characteristic elements. The first format of the descriptive image data and the coordinates of the characteristic elements are subsequently changed to an equivalent descriptive image and equivalent coordinates of the characteristic elements having a second format.

Abstract: The process consists of producing a first binary image (104) from descriptive data of an integrated circuit (or another type of object) to be inspected, the data being stored in a data base (102). Real images of characteristic elements of the integrated circuit to be inspected are then acquired (200) and processed so as to be applicable (300) to the binary image, as a function of their associated positions. A this obtained synthesis image is considered as a reference image with which are compared the images of the circuits to be inspected. This process is applicable to numerous types of industrially produced objects requiring a very precise inspection.
