Abstract: Water leaks and other anomalies in irrigation systems may be detected by analysis of energy consumption data captured from a utility power meter, and particularly energy data from smart meters that service water pumps. Furthermore, water usage can be measured indirectly from the energy required to move it given an understanding of its operating condition that ties water flow and electrical power. Unlike existing solutions that use water meters or other sensors, embodiments of the present method described herein detect water leaks and other anomalies from the electrical load for the water pump(s) and track the operating condition of the pump.

Abstract: Described are apparatus and methods that automatically generate recommendations to growers. Using various different sets of data relative to a predetermined tract of agricultural land, typically including both imagery as well as electrical usage, they are processed together to make informed decisions regarding the state of the land, particularly with respect to water usage.

Abstract: Water leaks in irrigation systems may be detected by analysis of water pump energy consumption data captured from a utility power meter. Unlike existing solutions that use water meters or acoustic sensors, embodiments of the present apparatus and methods described herein detect water leaks based upon the electrical load associated with the water pump(s) in irrigation lines. These methods have the advantage of not requiring any extra hardware at the site of the irrigation system.

Abstract: A wavelength-selective optical switch for switching arbitrary wavelengths between optical fibers in mesh networks, using interference filters for separating optical wavelengths, and two-dimensional arrays of micromirrors for switching. Broadband switch inputs and outputs are provided for adding and dropping arbitrary wavelengths at each node of the network. A two-stage multiplexer and two-stage demultiplexer are provided to simplify the free-space demultiplexer and multiplexer. Mechanisms are provided that allows full non-blocking functionality in the presence of finite yield of the micromirror arrays.
