A method and system for generating a spatial signature for a frame of a video object. The nut and body are adapted to be threadably coupled together by relative rotation therebetween. The openings are aligned in the same direction and expose at least a first sidewall and a fourth sidewall of each of the two bond pads. The apparatus includes a main component body including an umbilical comprising hoses for lining and air components and electrical power and signals, an impingement block for mixing the liner and remotely controlled by a termination rod. It discloses several aspects of the light pipe element aimed at improving the illumination of the targeted area for the aforementioned purpose, including the shape of the light pipe ends, the use of a refracting coat on the back of the light pipe and the shaping of the light pipe front surface to focus the light rays on the target surface. The electrical socket may be a power cable receiver on an electrical appliance, or a power supply socket.
