A method and structure for adjusting the wavelength output of a semiconductor device is described. It is the object of the invention to provide a system of sliding element comprising a base body and a counter-body which has a reduced mass with a sufficient strength and which achieves improved properties of friction and wear. The absorbent structure further comprises particulate superabsorbent polymer which can either be blended with the particulate discrete acquisition cells in the absorbent laminate, or provided in a separate absorbent layer of the absorbent structure. The notification message specifies information related to the detected change according to a predetermined format that can be processed by the first node. The second thickness being less than but not within 10% of said transition thickness.
