Abstract: A non-invasive portable apparatus for analyzing the performance of gas-filled window glazing units is disclosed. The operation of the apparatus is based on discharging the spacing between the panels (2a, 2b) of the window glazing unit (1) by applying rapidly alternating electrical field to the spacing between the panels of the window glazing unit, on collecting and analyzing the emitted discharge light in different structural intervals. The discharge is created by a needle-like electrode (5), and the inner conducting layer (2a) of the glazing unit serves as another electrode. The localization of the discharge in the vicinity of the end of the needle-like electrode (5) makes it possible to collect the emitted light without routine adjustment of the optical system.

Abstract: Traffic load in a congested cell in a mobile communication system is controlled by handovers into nearby cells which are less congested. Parametrisation and signalling are reduced based on integration of the functionality in one network element.
