    Abstract: PROBLEM TO BE SOLVED: To decode an incident pulse signal of the ultra wideband type through digital processing. SOLUTION: The incident pulse signal of the ultra wideband type conveys digital information encoded by using pulses in a known theoretical shape. A decoding device is equipped with an input means which receives the incident signal and sends a base signal out, a preprocessing means which is so adapted as to receive the base signal and sends out an intermediate signal representing the code of the base signal with respect to a reference, a means which samples an intermediate ISN signal and sends a digital signal out, a synchronizing means, a decoding means, and a digital processing means which is so adapted as to correlate the digital signal with a reference correlation signal corresponding to a theoretical base signal arising from the reception of the theoretical pulses having the known theoretical shape.

    Abstract: The invention concerns a device for processing a digital image comprising at least one contour region, including sharpness processing of the contour region. The sharpness processing includes converting data of the level of pixels of the contour zone into initial main data (step 2), ranging between a minimum value, for example 0 and a main value based on the amplitude of the contour, a sharpness sub-processing performed on said initial main data so as to obtain final main data (steps 3 to 10), and converting the final main data into final data of levels (step 11).

    Abstract: A device is provided for calculating mutual phase shift of first and second incident signals. The device includes a first pair of blocks associated with the first incident signal, a second pair of blocks associated with the second incident signal, checking circuit, and post-processing circuit. Each of the blocks has storage elements for storing a predetermined set of samples of the corresponding incident signal. In the presence of minimum samples or maximum samples of both incident signals, the checking circuit stores a first set of samples relating to the first incident signal in one of the blocks of the first pair and a first set of samples relating to the second incident signal in the counterpart block of the second pair, and then stores the following sets of samples of each incident signal alternately in the two blocks of each pair. The checking circuit delivers a block validation signal when a set of samples has been completely stored in the storage elements of one of the blocks. The post-processing circuit determines the phase shift of the first and second incident signals when two block validation signals are delivered for two counterpart blocks of the two pairs. Also provided is a digital disc reader that includes such a device.

    Abstract: Procedure in which the base length of the signal (1T) is first determined for an impulse (SMP) signal where all impulses last for a multiple of the base length signal. This is carried out in an initialization phase in which reference values (1T-14T) are determined. A correction procedure is also followed for a current distance and a comparison error is generated. An Independent claim is made for a device for reading binary data from a CD-ROM or a DVD disk.

    Abstract: L'invention porte sur un procédé de traitement d'une image numérique qui comporte au moins une zone de contour, comprenant un traitement de netteté de la zone de contours. Le traitement de netteté comporte une conversion des informations de niveau de pixels de la zone de contour en des informations principales initiales (étape 2), comprises entre une valeur minimale, par exemple 0 et une valeur principale fonction de l'amplitude du contour, un sous-traitement de netteté effectué sur ces informations principales initiales de façon à obtenir des informations principales finales (étapes 3 à 10), et une conversion des informations principales finales en des informations finales de niveaux (étape 11).
