Abstract: A backflow preventer for preventing a reverse flow of water in a plumbing system including a body having an inlet and an outlet. The body forms an intermediate zone between the inlet and outlet. An inlet check valve prevents the reverse flow of water from the intermediate zone through the inlet. An outlet check valve prevents the flow of water from the outlet into the intermediate zone. An inlet pressure sensor, an intermediate pressure sensor and an outlet pressure sensor provide readings for the respective zones. A controller monitors a pressure differential between the outlet pressure zone and the intermediate pressure zone to compare the pressure differential to a pre-set range. The controller generates a warning/error message when the pressure differential is outside the pre-set range. The controller can also monitor an inlet pressure in the inlet zone to generate a message if the inlet pressure varies inappropriately.

Abstract: Disclosed herein is a novel method to fabricate magnetic silica nanomembranes using thin polymer cores based on silica deposition and self-wrinkling induced by thermal shrinkage. These micro- and nano-scale structures have vastly enlarged the specific area of silica, thus the magnetic silica nanomembranes can be used for solid phase extraction of nucleic acids.

Abstract: In some aspects, a computing system may authenticate a user before blockchain functions may be performed and provide obstacles to prevent brute force attacks in decentralized computing systems or other distributed computing system environments. The computing system may use a smart contract to assist with authenticating a user. As authentication attempts fail, the computing system may increase a network usage cost associated with authentication. By doing so, the security of a computing system may be improved by making it cost-prohibitive for malicious actors to perform brute force attacks. Further, a computing system may use a variety of biometric information that may provide additional verification and security when authentication is performed.

The tamper switch is configured to detect a change in a position of the at least one shut-off valve and generate a tamper signal in the event the at least one shut-off valve is closed or partially closed. When a backflow discharge event occurs, a signal is sent to the fire panel triggering the building fire alarm as well as sending an alert to the local fire department and facility owner.
