A power inlet socket includes a socket body; live and neutral terminals provided on the socket body, and each having a first pin connected to the power plug and a second pin soldered on the substrate. A polymerization process incorporating the present catalyst composition produces a high-stiffness propylene-based polymer with a melt flow rate greater than about 50 g10 min. Through the retrieval and filtering of business information, the business form includes dynamically generated business information data fields consistent with the filtered business information. The light gun is adapted to be capable of separately detecting a blue, red or green light pulse and the X-Y coordinates of the target shot position is determined on the basis of the colour detected by the light gun and the length of time which elapses between the start of the second vertical refresh cycle and the detection of the red, blue or green light pulse. Each patterned common electrodes includes a plurality of electrode branches, and at least one slit disposed between two adjacent electrode branches.
