Abstract: The present invention is directed to an intelligent water management irrigation system for monitoring the total water usage for a billing site and preventing cumulative water usage from exceeding a water budget by adjusting the amount of water used for irrigation. Irrigation zone priority values are selected for each irrigation zone that specify a percentage of the full water need that the foliage in the zone can survive and are saved in an intelligent water management irrigation (IWMI) controller. The IWMI controller receives water usage information originating from a property's water meter and compares the measured water usage with the allowable water budget. Water usage is tracked separately for the household use and landscape use (irrigation). Prior to each irrigation cycle, the IWMI controller estimates the amount of water that will be needed by the landscape and for household use during the remainder of a billing cycle; household use is given precedence over landscape use.

Abstract: The present invention is directed to an irrigation controller, method and software program product for generating valve control signals for energizing a valve. The irrigation controller includes a valve actuation control module selectively coupled each of plurality of control nodes and generating a valve actuation control signal thereon. The valve actuation control signal is a continuous control voltage over a plurality of control signal periods for selectively energizing the selected irrigation valve. Also integrated in the irrigation is a valve chatter module for selectively coupled each of plurality of control nodes and generating a valve chatter control signal thereon. The valve chatter module selectively and, intermittently, energizes the selected irrigation valve. The irrigation controller may further include a remote controller of remotely controlling the irrigation controller.

Abstract: An improved methodology is implemented in a computer network comprising a plurality of computers connected to a corresponding plurality of network controllers. Each network controller is assigned a unique identification number. In turn each network controller is coupled to a corresponding device. The device is an input/output peripheral, typically a printer, plotter or modem. Bidirectional communication may occur between any one of the computers through the network buffers with any one of the device to allow integration of the output device and the software application running the computer, according to the status and type of device, such as occurs in computer assisted design software, which provides output to plotters and queries the plotter for different operational parameters. Bidirectional communicatiton also occurs in the instance where a modem is used as one of the devices.
