By using a spectral reflectance of a projection plane or color information under a light source, which is stored in wall color storage means 4, matrix calculation means 5 calculates a conversion matrix, and mixing amounts R, G, B of primary colors of an input image are converted into corrected mixing amounts R\u2032, G\u2032, B\u2032, and they are projected by means of a projector. More specifically, the system includes one or more portable network devices operable to support the seamless operation of a self-initializing, self-healing, adaptive portable network. During execution, when one of the breakpoints is hit, the debugger determines whether the corresponding method is being called from the user-specified location in the code. The lights can be similarly provided with a variety of other headgear types including rigid safety hats and rigid fire fighters helmets to name a few. The at least one token-based rule indicates a timeout associated with the unsecured device. Such a wake control device, with or without pivoting about the second axis, may also be secured directly to an outboard drive as well.
