Abstract: A convenient, water-saving and labor-saving FROG irrigation controller and system are provided, which determine the appropriate water budget and schedule for the property's landscaping based on evapotranspiration data for the geographic area, any regulation data, and property-specific data, with consideration given to reduction in watering days, increase in soil watering depth, and day of year. Once set, the FROG controller provides incremental adjustments over the course of the year; the homeowner no longer needs to re-set the watering program seasonally to automatically comply with local mandated and voluntary watering restrictions. One aspect provides a web-based wizard that is used to determine a customized water budget/schedule which is input into the FROG controller. Another aspect provides an integration of a network of FROG controllers with a central command unit.

Abstract: A safety system for mining equipment is provided having a proximity-based system with a marker field generator in an explosion-proof housing. The generator has a resonant circuit with an inductive reactance that is provided by a ferrite rod wound with an electrical conductor. Also provided is an RF receiver to receive information about the strength of the generated marker field from a sensing device used by a worker. The system provides for a personal alert device, carried by personnel to be kept at a safe distance from the mining machine, the personal alert device being capable of detecting the marker field. Also disclosed is a geosteering system that stops the cutting of a continuous miner when the cutter reaches an interface between a mineral being mined and an adjacent formation that is not to be mined.
