| 405037000 | Control means responsive to sensed condition | 10 |
| 20080219768 | Foundation Watering System - A foundation watering system is provided having a water supply, a water distribution system, a hygrometer and a controller that allows water from the water supply to flow into the water distribution system based upon data from the hygrometer. | 09-11-2008 |
| 20080298896 | Method and Device for Waterproofing and Draining Off Infliltrated Water in Hydraulic Structures - A sheathing of elastically deformable waterproofing sheet material ( | 12-04-2008 |
| 20090185862 | Flood control system - A system for controlling flooding comprises a fitting coupled to a preexisting drain pit in a building, a pipe connected to the fitting and having a portion extending upwardly therefrom, and a first drainage line extending from the pipe to a drainage area for discharge of water from within the drain pit. The fitting may be sealingly coupled to the preexisting drain pit. According to one aspect, the fitting may at least partially extend into the drain pit. For example, the fitting may extend at least four inches into the drain pit. Further, a cap may be attached to an open end of the pipe remote from the fitting. In some instances, the system may further comprise a pump within said drain pit underlying the fitting pump. This pump may be a sump pump or a removable pump. Even further included may be a control for operating the pump. | 07-23-2009 |
| 20090252556 | DEGASSING APPARATUS FOR GOLF COURSE WATER DRAINAGE SYSTEM - Improved golf course drainage systems ( | 10-08-2009 |
| 20100296870 | SUBIRRIGATION SYSTEM - A subirrigation system | 11-25-2010 |
| 20120243940 | APPARATUS FOR CONTROLLED RELEASE OF WATER FOR PLANTS - An apparatus for controlled release of water for plants includes a chamber; a damper that allows the water into the chamber; and a float having a drain tube. The float is adapted to rise with the water level in the chamber to a predetermined upper level, sink, and substantially release the water through the drain tube. The chamber is positioned inside or adjacent to a grow bed. Water from a fish tank may be pumped into the grow bed through a conduit in the chamber, and the apparatus periodically drains a measured amount of water back to the fish tank. | 09-27-2012 |
| 20130223934 | DEVICE, SYSTEM, AND METHOD OF IRRIGATION - An irrigation system for irrigating a plant having a root comprises: a valve to begin irrigation from a water source at a first time-point; a moisture sensor to sense moisture at a second, subsequent, time-point, said moisture sensor being located underground at an insertion depth between ground surface and a maximum depth of the root; a water drainage speed calculator to calculate a water drainage speed based on the first time-point, the second time-point, and the insertion depth of the moisture sensor; and a target drainage time calculator to calculate a remaining time for irrigation, based on the calculated water drainage speed and further based on a difference between the insertion depth and the maximum depth of the root. | 08-29-2013 |
| 20130272791 | MOISTURE RESPONSIVE IRRIGATION METHOD AND APPARATUS - An irrigation device comprising a moisture responsive barrier is provided. At least a portion of the barrier has perforations, at least some of the perforations are associated with a water swellable material. The perforations are configured to open as the water swellable material loses moisture and dries out and are configured to close as said water swellable material is exposed to and absorbs water, such as during a watering step. According to another aspect the irrigation method includes the steps of positioning a perforated barrier between a source of irrigation water and an area to be irrigated, wherein the perforations are associated with a water swellable material; exposing the water swellable material to water to cause the water swellable material to swell to close the perforations; and permitting the water swellable material to dry, to open the perforations, whereby the opening and closing of the perforations regulates the amount of irrigation water being applied across the barrier in the irrigation method. | 10-17-2013 |
| 20150147119 | TWO-WIRE CONTROLLING AND MONITORING SYSTEM FOR IN PARTICULAR IRRIGATION OF LOCALIZED AREAS OF SOIL - The present invention relates to a method for providing watering or non-watering of a specific area of soil through a first plurality of irrigation valves ( | 05-28-2015 |
| 20160048135 | AUTOMATED FLOOD IRRIGATION SYSTEM AND METHOD OF USING THE SAME - A method for flood irrigation includes releasing water from a riser valve for flooding a portion of a field through a control of a corresponding riser device of a plurality of riser devices, wherein the corresponding riser device is deployed at a location proximate to the riser valve, receiving a wireless signal from a corresponding sensor device of a plurality of sensor devices for a detection of a flood condition, wherein the corresponding sensor device is deployed at a location proximate to where the water from the riser valve is expected to flood; and stopping the release of the water from the riser valve. | 02-18-2016 |
