A method includes reading content of network traffic that arrives at a network port of a network switch of a mesh of network switches. The present invention directly employs polarized electrical charge storage devices such as polarized capacitors or electrochemical batteries in general AC applications with a novel circuit topology. The color model value for each pixel in the saturation region is then adjusted by a corresponding adjustment. The sensor may be manufactured from layers of olefin film and conductive ink to form capacitive sensing elements. A consistent navigation experience is supported at various scales, and real-time collision detection is provided.
