Abstract: A balanced energy and energy producing system is composed of an input device with a driven generator connected thereto. The signal of the generator actuates a controller having multiple grading parameters and battery monitoring parameters. The controller supervises the generator to supply the electrical energy needed for the battery and also, based on the strength of the generator signal, drives an output device up to a predetermined power rating according to the multiple grading parameters so as to establish an uprated power source management system applicable to hybrid power source electro mobiles, including bicycles, and domestic power generation thereby achieving efficient energy utilization.

Abstract: A warp knitted fabric for a zip mounted thereon has a base fabric having first threads, second threads and third threads, wherein the first threads are extended along a warp-wise orientation of the base fabric to form wales and are lapped to form crochets and the second and the third threads are extended along the warp-wise orientation of the base fabric and are repeatedly and cross lapped over two of the wales. The base fabric has a rare portion, which is a region of the base fabric having less of the third threads than the other region thereof. The base fabric further has fourth threads, which is made of a material with a well elasticity, to form an elastic portion. The elastic portion has a side overlapped with a portion of the base fabric on which the third threads are knitted to form an overlapped portion.
