Automated groundwater monitoring system and method

A method of monitoring the quality of water at a ground water sampling site without human intervention. Water at the sampling site is purged until at least one preselected purge criterion is satisfied. At least one water quality attribute is automatically measured at the sampling site, and the quality of water at the site is determined based on the measured water quality attribute. The method is performed by a system including a control unit which, in accordance with a computer program, controls the taking of water quality attribute measurements at the sampling site. The control unit may be equipped with a port for downloading data to a technician on site and with a transceiver for communicating data to a base station via a communications network.

Drainage system and method for artificial grass using spacing grid

A drainage system is provided for a synthetic grass turf assembly having a flexible and water permeable sheet backing for installation on a supporting soil substrate to provide a game playing surface. The draining system of the present invention prevents water from accumulating on the turf surface, which could cause the top-dressing layer to “float” and be moved by inundation. The draining system of the present invention includes a spacing grid disposed between the backing of the turf. The spacing grid is structured to permit water not only to be drained vertically through the spacing grid, but also to be drained horizontally through the spacing grid to the edges of the field. The spacing grid is made from one or more types of geotextile or plastics material with an adequate flexibility to improve the impact absorption capabilities and resilience of the synthetic grass turf assembly.

Systems and methods for water harvesting and recycling

ActiveUS20110174706A1Reduce sunken and uneven surface areaReduce water billsWater treatment parameter controlWater cleaningWater useSprinkler system
This disclosure describes a system for recycling and reusing water from sprinkler systems to water or irrigate a yard or an area of land. The system includes a water reclamation tank that stores water captured from beneath the area of land. When it is time to water the area of land, the sprinkler system draws water from the water reclamation tank. A portion of this water is then recaptured and supplied back to the water reclamation tank for further storage until the next time the sprinkler system is activated. This cyclical process occurs repeatedly and enables a significant reduction in the amount of freshly supplied water used to maintain the area of land.

Active pulse blood constituent monitoring

InactiveUS20050272987A1Ability to determinePreventing any perturbationMachine supportsConstructionsBlood componentOptical property
A blood constituent monitoring method for inducing an active pulse in the blood volume of a patient. The induction of an active pulse results in a cyclic, and periodic change in the flow of blood through a fleshy medium under test. By actively inducing a change of the blood volume, modulation of the volume of blood can be obtained to provide a greater signal to noise ratio. This allows for the detection of constituents in blood at concentration levels below those previously detectable in a non-invasive system. Radiation which passes through the fleshy medium is detected by a detector which generates a signal indicative of the intensity of the detected radiation. Signal processing is performed on the electrical signal to isolate those optical characteristics of the electrical signal due to the optical characteristics of the blood.

Hard reinforced concrete revetment slope biological repairing method

The invention discloses a hard reinforced concrete revetment slope biological repairing method, which is characterized by comprising the steps of: roughing a concrete revetment and constructing drainage ditches at set intervals; digging a water collecting tank on one side of the cross of the revetment and a road, reserving an opening at the joint of the drainage ditch and the water collecting tank, and constructing a watertight concrete overflow bank; filling gravels in the water collecting tank and the drainage ditches; and welding earthwork grids by high-density polyethylene stripes on the protection slope, laying gravel cushion coats in the earthwork grids, and finally pouring biological slurry. The method has the advantages that: the whole project is stable and safe; rain flows into the water collecting tank and passes through grave areas, non-watertight sand-free concrete, a slope cushion coat, plant roots and the like to seep into rivers, so water quality is improved to a relatively large extent; when rainfall runoff is overlarge, the rain overflows from the overflow bank and passes through the graves of the drainage ditches, so the water quality is also purified to a certain extent, meanwhile the slope is protected; the biological slurry poured onto the slope is prepared from biological materials, and has certain anti-erosion strength and can be used as a substrate for plant growth, so the cost is low and the operation is simple.
