A network of throwable cameras is disclosed. Nanodispersion formulations of embodiments of the invention include a taxane, an oil, a non-ionic surfactant, a non-aqueous solvent, and an organic acid component, wherein the organic acid component is soluble in the non-aqueous solvent and the amount by weight of non-ionic surfactant is equal to or greater than the amount by weight of non-aqueous solvent. Additionally, the maintenance cycles can be adjusted to be approximately the same in the image forming apparatuses. Information gauges can be realized through use a memory that stores a plurality of images comprising views of an information gauge of interest showing a variety of different readings. When the setting of various types of components necessary for photographing other than the lens groups has finished, even if the zoom lens groups are moving to their home positions, the digital camera is in a state in which photographing is possible. The individual detectors may be of different rectangular shapes and mounted on a motherboard.
