A method for manipulating a quantum system comprises at least one mobile charge carrier with a magnetic moment. The display panel has an active area. At least each first folded edge includes a groove through one rim and a hooking projection on an opposite rim. The roller nips are spaced a uniform distance apart. The pivot locations in the four bar linkage create a mechanism that simultaneously controls rotational and translational movement of the upper segment during flexure of the lumbar. Each vector is specified at a pixel center in an image defined at the time between the first and second images.
