Methods and systems for transmission of noise parameters for improving automatic speech recognition are disclosed. The upper panel is domed while the lower panel has a corrugated like structure. In one embodiment, an audible signal is generated when the cap locks. The local dynamic range is not changed significantly in some embodiments. When the colorant system is added to a base paint it desirably provides a mixture having a drop in viscosity of less than about 50%. The first photopolymerizable material is polymerized by irradiating the first ultraviolet light to form a plurality of first liquid crystal droplets.
