Abstract: The invention relates to a textile item comprising a receptacle (20) for housing a portable electronic device (10), characterised in that the above also comprises a functional marking (21-24) on an accessible face (20) thereof, which comprises at least one code the distribution of which coincides with the control bodies of the portable electronic device, such that each code may be placed in correspondence with a control body on the portable electronic device (10) when the portable electronic device (10) is placed in the receptacle (20).

Abstract: The present invention relates to a method for characterizing at least one photorepeater and a same set of patterns implemented on several regions of a wafer, including the steps of making a standard reticle defining at least one first series of at least three identical reference patterns, which are not aligned; successively exposing several regions of a standard wafer by varying the illumination dose from one region to another; measuring the respective dimensions of the reference patterns reproduced on the different regions of the wafer to determine, for each illumination does, the mean dimension of the reference patterns; and performing a linear interpolation of these mean dimensions.
