Abstract: A mobile apparatus is provided for exchanging data objects over several network. The mobile apparatus exchanges data objects of a first data format over a first network and exchanges data of a second data format over a second network. The mobile apparatus comprises configurable processing means. When configured, processing means converts data of the first format received from the first network to data of the second format. Processing means then forwards converted data to the second network.

Abstract: A plasma picture screen fitted with a phosphor layer comprising a red phosphor activated by Eu3+ shows an improved red color point (x≧0.64 and y≦0.35) and shorter decay times &tgr;1/10 as compared with the standard phosphor (Y,Gd)BO3. The phosphor according to the invention has a lattice in which the activator Eu3+ occupies a location which has no inversion symmetry.

Abstract: The invention relates to a method of and a device for determining the position of a medical instrument (4), introduced into the body of a patient (2), relative to a periodically moving organ (3) of the body, which method includes the steps of: a) determining the spatial position (c, r) of the medical instrument (4) and of a reference probe (6) while acquiring at the same time a periodic motion signal (E2) which relates to the periodic motion of the body organ (3), b) selecting a 3D image data set (p) from an image data base which contains 3D image data sets (p) of the body organ (3) which have been acquired pre-operatively and simultaneously with the same motion signal (E1) and are associated with individual motion phases (e1, e2, . . . ), in such a manner that that 3D image data set (p) is selected which is associated with the motion phase (e1, e2, . . .
