-PC-Programmed irrigation control system (US7010395B1)
Resumen: A free-standing field irrigation controller is selectively programmed by a personal computer over a radio link. The computer is equipped with software that displays a screen with seven horizontal time bands representing one day each, arranged vertically to display one week's time. Box icons representing watering settings for a plurality of zones can be dragged and dropped onto the time bands, copied and modified thereon as desired, to form a freely selectable watering schedule. Other selectable screens allow odd-days or even-days watering, sophisticated interval watering, global watering time adjustment, and a variety of manual functions. Selectable portions of the main screen can be enlarged as desired. Based on the selected schedule, the computer calculates and displays the monthly cost of water. Selected zones can be temporarily disabled to deal with weather or maintenance issues. A handheld global shut-off and manual watering remote and/or a separate radio-linked computer may be used in field maintenance.

-Irrigation control system (US2006161309A1)
Resumen: An irrigation control system and method for controlling irrigation based on weather data. Weather data such as wind, temperature, solar radiation, humidity, and rainfall, may be collected at one or more weather stations for a region. The weather data may be compiled on a computer and transmitted to a paging broadcast service. The weather data may then be transmitted by the paging broadcast service to controller interfaces associated with irrigation systems throughout the region. The controller interfaces may adjust irrigation controllers associated with the irrigation systems based on the weather data such that the proper amount of water is applied. This allows the water to be used more efficiently and the health of the landscape to be improved.
