Patent ID: 7065886

Claim:
A system for localizing an area in space in relation to a predetermined point on a surface of circular form, wherein the surface is divided into six equal main sectors, each sector being divided into three equal sectors and by two circles centered on the center of the surface so as to obtain nine zones of a first rank, each zone of a rank n, n being an integer number greater than 1, being divided successively in a same manner into nine zones of higher rank n+1, a predetermined respective number from 1 to 6 being attributed to each of said six main sectors, a predetermined respective number from 1 to 9 being attributed to each of the zones of first rank and to each of the zones of rank n+1 in the zone of rank n, a zone of rank n being localized by a zone reference sequence having n+1 digits containing the number of said zone, the respective numbers of all of zones of lower ranks n−1 to 1, and the number of the main sector, in which said zone is located, said system comprising: means for detenniing the zone reference sequence of a zone of rank n in which is located an area to be localized in the surface, n being the maximum value such that the surface of the area to be localized is included in said zone of rank n, and means for manipulating said zone reference sequence.
