Date Oct. 4, 1990.The invention relates to a decoration and a method of making such decoration comprising a plurality of separate, artificial plant parts. The method is characterized by overlappingly connecting separate, juxtaposed first plant parts at a distance from a front edge of the respective plant part, and of overlappingly connecting a plurality of separate, mutually overlapping second plant parts to said first plant parts. As a result, an area of each of said first plant parts facing away from the front edge is covered, like the connection, by the overlapping portion of each of the second plant parts. The decoration is intended for use in the making of a wreath.

Abstract: Foreliggende oppfinnelse vedrører en automatisk ve- rifikasjon i et telekommunikasjonssystem relatert til personlig nummer, spesielt et universelt person- lig telekommunikasjonssystem ("Universal Personal Telecommunication" UPT). En vokalverifikasjon blir automatisk avgitt etter registrering av et nytt re- gistreringsnummer, og det nye registreringsnummer kan valideres som et ekte registreringsnummer. Det kan også utføres en testkobling med hensyn til det nye registreringsnummer, ved hjelp av en oppsetting av en kobling fra et tjenestestyrepunkt ("Service Control Point") (103) til det nye registreringsnum- mer og ved å la et ringesignal lyde, og deretter automatisk frakoble koblingen. Fremskaffeisen av den vokale verifikasjon av det nye registreringsnummer, valideringen av det nye registreringsnummer, samt oppsettingen av en testforbindelse vil i betydelig grad redusere risikoen for å føre inn og/eller re- gistrere et feil registreringsnummer.
