In various embodiments, the invention provides a clock generator andor a timing and frequency reference using an LC-oscillator topology, having a frequency controller to control and provide a stable resonant frequency, which is integrated with other, second circuitry such as a processor or controller. The antenna loop is positioned opposite a ground plane of a PCB. The process can refine the polypropylene backing polymer and face fibers of post industrial edge trim selvage, whole carpet construction post industrial scraps and pieces, as well as whole carpet post consumer scraps and pieces and in particular mixtures there of. The coded V-cut bittings are at a respective angle and are located at a respective vertical level. The keyboardmouse switching circuit and the USB bridge unit are selectively connected, whereby a switching of bridging channels is provided between at least two computers.
