A method of fabricating a dielectric piece which includes metal compound dots is provided. For example, whether an operation of waving the controller has been performed is determined based on at least one of a pointed position on a display screen by the controller and acceleration. The anisotropic light-diffusing film is a film formed by melt-extruding a mixture of at least two thermoplastic resins incompatible with each other. A finite-state automaton is generated from the input rules. The compositions comprise calcium; magnesium; selenium; manganese; zinc; potassium; vitamin E; vitamin A; alpha-lipoic acid; Allium sativum extract; Afecicago satiia extract; Chondrus crispus extract; L-cysteine; L-glutamic acid; glycine; and glutathione. In an embodiment, the motherboard includes remote fan speed control module and a signal module, each to be coupled with a fan over a communication medium.
