The two Remote Back-flow Detection and Shut-off Systems that are developed by this patent narrows the possible 12 month time span for contaminating back-flow by detecting and shutting off the back-flow while not changing the current installation or inspection methods of the double check valve assembly.

A detection system is provided for a distributed water infrastructure to determine a human health or lifestyle state from detected water usage patterns. The system receives signals indicative of water usage from at least one sensor upstream of a plurality of appliances, and determines from the signals a current water usage pattern. The system accesses a database of a plurality of stored water usage patterns, associated with a human health or lifestyle state, compares the pattern with stored water usage patterns and, based on the comparison, identifies a human health or lifestyle condition reflected by the current water usage pattern.

A method for determining the bacterial charge in a liquid or semi-liquid product, including: preparing a quantity of liquid or semi-liquid product to be analyzed; keeping that quantity of liquid or semi-liquid product at a preset measuring temperature (T.sub.m) and deriving values () representing an angle of electrical impedance of the liquid or semi-liquid product at predetermined time instants; deriving an indication of the presence of a bacterial charge in the liquid or semi-liquid product as a function of the time trend of the values () representing the angle of the electrical impedance.

Sampling devices for sampling an aqueous source (e.g., field testing of ground water) for multiple different analytes are described. Devices include a solid phase extraction component for retention of a wide variety of targeted analytes. Devices include analyte derivatization capability for improved extraction of targeted analytes. Thus, a single device can be utilized to examine a sample source for a wide variety of analytes. Devices also include an isotope dilution capability that can prevent error introduction to the sample analysis and can correct for sample loss and degradation from the point of sampling until analysis as well as correction for incomplete or poor derivatization reactions. The devices can be field-deployable and rechargeable.

Oil spill detection is crucial, both from an environmental perspective and the associated economic losses. Current optical oil sensing techniques, such as underwater microscopy and light scattering methods, mainly focus on detecting the properties of particles or organisms in water and often require costly equipment and sophisticated data processing. Recent studies on graphitic foam show its extraordinary pollutant absorbing properties, with high absorption weight ratios. Here we propose to produce a graphene foam based ultra-light material that changes its optical properties on absorbing oil species. The results demonstrate clear changes in optical transmission and scattering properties of graphene foam when exposed to various oils. The effective graphene foam sorbent can be easily integrated with optic fibers systems to detect the optical property variations and also to monitor oil presence/spillages remotely. Such sensors can also be used for underground oil exploration.

The present invention discloses a metal strip winding continuous reinforced thermoplastic composite pipe. The present invention adopts a method designed for grouping the winding metal strips to rationally distribute the winding mode of the metal strips, and at the same time, increases the hoop strength and axial strength of the pipe by using the feature of high strength of the metal strips, thereby improving the compressive capacity of the pipe; there is no bonding between the metal strip reinforcement layers, which improves the flexibility of the composite pipe and reduces the relative slippage between the metal strip layers; the production process is simple, and requirements for the equipment investment are small, thereby greatly reducing the manufacturing cost and ensuring the flexibility and seismic resistance of the pipeline.
