Abstract: Line components of raster data obtained by scanning an original map are digitized to thereby provide vector data for an electronic map. To automatically verify the accuracy of this vector data it is transformed into raster data using a desired algorithm, such as the Bresenham algorithm, and then the edges of the line components are transformed into sawtooth-shaped edges. This saw-tooth-shaped raster data (upper right, fig 4) is then XORed with the original raster data (upper left, fig 4). The remaining noise is then removed using a filter having a desired size eg of 2x2 pixels, thereby enabling the accuracy of the electronic map to be verified.

Abstract: Procédé de traitement d'un appel de service en réseau intelligent dans un point de commutation de service (SSP) qui comporte un processeur DTMF et est relié à l'échange local/de transit émetteur pour fournir un service en réseau intelligent. Le SSP reçoit un chiffre de l'autre échange dans un mode de signalisation R2MFC pour traiter un signal interurbain à partir de l'autre échange en générant une demande d'établissement de la ligne interurbaine à partir de l'autre échange. Le SSP analyse le chiffre reçu pour vérifier si un appel provenant de l'autre échange est un appel normal ou un appel de service en réseau intelligent dans lequel l'information du souscripteur doit être reçue en cours de service. Si l'appel provenant de l'autre échange est l'appel de service en réseau intelligent, le SSP recueille un numéro d'appel et une catégorie d'appels à partir de l'autre échange, déclenche le mode de signalisation R2MFC et forme un circuit de conversation avec l'autre échange pour communiquer directement avec un utilisateur de service. Ensuite, le SSP actionne le processeur DTMF et un dispositif d'émission d'annonce pour commander à l'utilisateur de service de ...

Abstract: The method initially involves forming a buried collector (2), collector thin film (3), and collector sink on a semiconductor substrate. On the collector structure are formed a silicon oxide film (8), a polysilicon film (9) for a base electrode, a nitride film, and an oxide film. The silicon oxide film is photolithographically exposed and an insulating spacing layer formed on the exposed region side, thus limiting an active region. Then the collector thin film is exposed, using the existing structure as a mask, and a lateral auxiliary film formed for component separation. An ion implantation of a dopant forms a selective collector region (10) in the active region. Then the auxiliary film is removed, the exposed part etched, and a separating, flat trough (17) is formed. Then a side polysilicon film (18) and a self aligning base are formed. A heat treatment after th formation of the collector sink follows which provides an oxide film on its upper section and activates dopants within the collector sink.
