Abstract: Methods and systems are presented for identifying user accounts selectively authorized to modify at least respective first and second fields of a data table, obtaining field-dependent validation rules selectively applicable to the respective fields, transmitting spreadsheet files to devices associated with the respective user accounts, filtering user-modified spreadsheet files so that the first field is selectively accepted from the first device and the second field is selectively accepted from the second device, allowing the values of the first and second fields to be edited contemporaneously, and recording an edited version of the data table.

Abstract: An automatic irrigation and sprinkling system for applying irrigation water or airborne dispersed water to a particular area. A precipitation sensor is included for incrementing a counter based upon the sensed precipitation. During a scheduled irrigation event, power is applied to the system to open one or more solenoid valves to control the flow of water. This main power signal would flow uninterruptedly to the solenoid valves only if the counter was at a predetermined value. A value greater than this predetermined value during a scheduled irrigation event would cause the power to be interrupted to the solenoid valves and would allow the counter to begin decrementing. If the value of the counter reaches this predetermined value during the scheduled irrigation event, power would again be supplied to the solenoid valves, thereby supplying water to the predetermined area.
