  • SIMULATED RAIN WITH DYNAMICALLY CONTROLLED DRY REGIONS
    Publication number: 20150127177
    Abstract: A simulated rain enclosure includes a ceiling supporting a tightly packed two dimensional array of water ejecting ceiling tiles having a direct presence detector associated with each ceiling tile. Detection of one or more persons under one or more said water tiles by the direct presence detectors turns off water flow from each associated ceiling tile and to a defined region of the ceiling tiles adjacent to each associated ceiling tiles. Water flow is returned from any ceiling tile previously turned off but not currently in a defined region.
