A vehicular precipitation sensor which detects precipitation on a vehicle window includes an imaging array sensor directed at the vehicle window from inside the vehicle, and a control operable to detect precipitation at a surface of the vehicle window in response to an output of the imaging array sensor. The organic layer has a polymer of a vinyl compound represented by the following formula : wherein R1 and R2 are the same or different, each representing a hydrogen atom, a halogen atom, an alkyl group or an alkoxy group. A first pipeline structure carries a part of the heat exchange fluid from the heat gaining device to the heat releasing device. The specific gravity of the inner core is preferably less than the density of the outer core. The digital representation of the look is stored as a recipe for generating the creative alteration, and communicated from the production stage to at least one of the subsequent laboratory and post-production stages for applying the look to the captured motion picture footage during subsequent laboratory and post-production stages. Finally the removal of the organic phase of water-in-oil-in-water double emulsion enables the harvest a plurality of liposomes.
