Abstract: In some embodiments, a multistate memory cell includes; a storage loop comprising one or more superconducting devices and one or more inductive devices, the storage loop configured to maintain a quantized magnetic field representing a stored state of the multistate memory cell, the stored state from among a set of three or more distinct digital states; and at least three address lines each inductively coupled to the storage loop, wherein, in response to currents applied to the at least three address lines, the inductive couplings of the at least three address lines combine to force the quantized magnetic field to represent a particular one of the three or more distinct digital states.

Abstract: The system and method of the present invention provides comprehensive design and installation management for agricultural water management systems. Maps and grade profiles are created from data collected by Global Positioning devices in the field. Latitude, longitude, and elevation are triangulated from GPS data to develop contour, grade, and profile maps, used to design drainage systems in real time. Customer billing information and vendor pricing information are produced from map and grade profile data. Interfacing and machine control for machines used to install drainage and/or irrigation systems are generated from contour, grade and profile data. Data is exported and imported in common file formats for efficient data exchange.
