Abstract: The present invention is a method and system for determining the range of an RFID tag from an origin using radio-frequency identification (“RFID”) tags. An RFID tag with a unique numerical identifier is secured to an object. The RFID tag transmits its unique numerical identifier using RF signals, wherein the numerical identifier further comprises an array of extensions. The strength of each of the RF signals corresponds to an extension of the array of extensions. A receiver reads the RF signals and determines the unique numerical identifier and extensions being transmitted. An information processor interconnected with the receiver analyzes the unique numerical identifier and extensions from a predetermined index, and the information processor determines the range of the identity and range of the RFID tag from an origin.

Abstract: The present invention is an irrigation method and system for providing a user-defined flow rate to a field using variable sized orifices. The irrigation method and system includes providing a source of irrigation water. A first discrete area to be irrigated is defined and the volume of irrigation water to be disbursed to the first discrete area is determined based on the type of crop. A length of continuous irrigation conduit is provided so that the irrigation conduit is in fluid communication between the source of irrigation water and the first discrete area. The required diameter of each orifice is calculated based on the user-defined flow rate. Each orifice is made in the irrigation conduit as the conduit is installed in the field so that the irrigation water is disbursed to the first discrete area in an amount approximate to the user defined flow rate.
