Abstract: Systems and methods are provided for identification and discrimination of subpopulations within a mixture of particles. The systems and methods implement continuous calibration of the classification of particles within the mixture to provide consistency in operation and to reduce inter- and intra-batch processing variation. The systems and methods produce advantageously sorted particle products.

Abstract: A system and method for collecting and redistributing rainwater by catching rainwater using a conventional roofing and guttering system, piping the rainwater into a collection vessel for storing the rainwater, pumping the rainwater from the collection vessel through a hose; and redistributing the rainwater from the collection vessel via the hose. The system can comprise a rainwater filter that provides one or more filtration stages to rainwater collected. The rainwater filter has a filter reservoir that includes one or more outlets to communicate filtered water to the collection vessel and one or more overflow ports. The filter may also include a shutoff valve to regulate flow of water into the collection vessel, and a filter reservoir drain to avoid stagnation of water in the filter reservoir.

Abstract: A connection station or unit for use with an in-ground water station housing and a drip irrigation system, a soaker hose system, or the like, the station having a cap, a threaded pipe segment, a connector, and a filter and pressure reducer unit. The connector can be a nipple connector suitable for use with a drip irrigation system, a threaded connector suitable for use with a soaker hose connector, or any other type of connector suitable for connecting the invention to an irrigation system. The station can be used as an original installation or as a retrofit for currently installed in-ground irrigation systems.
