| 20110210187 | Automatic Sprinkler and Irrigation System - The present invention provides an irrigation system that allows user to input two soil moisture levels, i.e., the Dry Value and the Wet Value, by conducting a manual watering cycle, i.e., turning on the valves through a Controller when the soil needs watering and turning off the valves when the soil is sufficiently wet. The Controller keeps the soil moisture between the Dry and Wet Values by automatically turning on the valves when the soil moisture reaches the Dry Value, and turning off the valves when soil moisture reaches the Wet Value, at the user-determined desirable watering time periods of the day. In larger areas, the ground could be divided into multiple zones. The Controller could apply different Dry and Wet Values to different zones. The system's simplicity is further enhanced by the solar powered wireless moisture sensors. | 09-01-2011 |

The system comprises a plurality of sensors, preferably wireless, to control the sprinkler heads, either directly or through a controller. The system enables precise control over irrigation times for the areas covered by each sprinkler head. The system also enables each sprinkler head to control its on/off and duration decisions based on receiving data from a sensor within an irrigation zone of an automatic sprinkler system. | 02-24-2011 |
| 20080223950 | MULTI-ZONE SPRINKLER SYSTEM WITH MOISTURE SENSORS AND CONFIGURABLE SPRAY PATTERN - An irrigation system comprises sprinkler heads with an electrically configurable spray pattern, moisture sensors, and a controller. Based upon input signals from the moisture sensors, the controller dynamically configures the spray pattern of the sprinkler head to allow more water to fall on areas that need to be watered and less water to fall on areas that do not require additional water. The irrigation system can additionally comprise fire sensors. Based upon input from the fire sensors, the controller activates the sprinklers. | 09-18-2008 |
| 20120261487 | Computer-Operated Landscape Irrigation And Lighting System - A multi-zone landscape irrigation and lighting system includes a personal computer equipped with a detachable wireless remote, and a multi-station controller operating a plurality of irrigation valves and lighting circuits in accordance with schedules wirelessly transmitted to it by the computer through the remote. When detached from the computer, the remote can wirelessly operate selected irrigation or lighting zones manually. The computer has an intuitive graphic user interface capable of using actual zone photographs to identify individual zones in a strip of zone icons. The icon strip is movable past a lens-like window, the zone icon under the lens at a given time determining the zone currently programmable. A residential system can be operated by a contractor from the street, and the system can be programmed by e-mail from the contractor's shop. Fully automatic operation may be derived from data obtained over the Internet. | 10-18-2012 |

| 20120126026 | Moisture Probe and System - An advanced landscape irrigation control system that integrates a soil moisture probe with a timer-based controller which can be used to directly control a single irrigation zone without need for a separate timer-based controller. The invention is equally capable of being installed as a soil moisture sensor that operates under the control of a traditional timer-based controller. The moisture probe and system disclosed in this invention is fully buried in the soil and electrically connected to the water solenoid-valve(s), measuring temperature and soil moisture content using a capacitive-based probe in determining water solenoid-valve(s) operation. The device has no user settings and requires no calibration, including determining optimal soil moisture content by a unique method of recognizing soil signatures, or the unique electrical response of soils to water. | 05-24-2012 |
