Abstract: In a first embodiment, the present invention is a valve insertable into a sewage line in order to prevent backflow into a structure. The valve includes a mouth formed therein which corresponds to the size of an inlet of the sewage line and means for rotating for rotating the valve within the sewage line. Rotation of the valve to an open position aligns the mouth with the inlet of the sewage line to permit flow through the sewage line and rotation of the valve body to a closed position rotates the mouth away from the inlet of the sewage line to prevent flow through the sewage line. In a second embodiment, the present invention further includes a conduit adapter that replaces a converging section of the sewage line in order to retrofit the valve into a sewage line where the valve would otherwise not fit therein. Additionally, in either the first or second embodiment, the present invention provides for the simultaneous purging of the sewage line by attaching means for purging to the valve.

Abstract: An electronic device includes a compound designed to raise a surface tension of a water-based solution. The electronic device may include a vent feature to allow air to pass through the vent feature such that the air reaches a component in the electronic device. The vent feature may include a first vent structure and a second vent structure, both of which combine to confine the compound. When the water-based solution passes through an electronic device opening, the water-based solution may reach the first vent structure. If a surface tension is sufficiently low, the water-based solution may pass through the first vent structure. However, the water-based solution may then reach the compound causing the compound to dissociate, forming form positive and negative ions that attract molecules of the water-based solution. Then, the water-based solution surface tension increases and does not pass through the first vent structure or the second vent structure.

Abstract: By monitoring pressure transients in a liquid within a liquid distribution system using only a single sensor, events such as the opening and closing of valves at specific fixtures are readily detected. The sensor, which can readily be coupled to a faucet bib, transmits an output signal to a computing device. Each such event can be identified by the device based by comparing characteristic features of the pressure transient waveform with previously observed characteristic features for events in the system. These characteristic features, which can include the varying pressure, derivative, and real Cepstrum of the pressure transient waveform, can be used to select a specific fixture where a valve open or close event has occurred. Flow to each fixture and leaks in the system can also be determined from the pressure transient signal. A second sensor disposed at a point disparate from the first sensor provides further event information.
