A dynamically configurable logic gate includes an input summer for receiving a first input signal and a second input signal to generate a summed input signal. This structure solves difficulties of mini-motors such as difficulties of handling the motor, difficulties of mating those elements each other, and time-consuming bonding action. 1% to about 20%, by weight of the composition, of solubilized, water-soluble, uncomplexed cyclodextrin and an effective amount of at least one ingredient to improve the performance of the composition selected from the group consisting of: cyclodextrin compatible surfactant; cyclodextrin compatible antimicrobial active; and mixtures thereof. Then, an estimate of antenna pointing error at a particular time going forward is predicted based on the learned model of the periodic behavior of the antenna pointing error. These complexes may enhance the pharmacodynamic properties of biologically active moieties. The apparatus and method enables a magnitude of a magnetic field to be cyclically modulated when a substrate to be treated is etch processed.
