    摘要: A system for leak detection and containment is disclosed. The system comprises an impermeable containment casing comprising of a solid extruded material wherein the containment casing encompasses a pipeline deployed therein. The system may further comprise a plurality of separating strips to create an annulus between the pipeline and the containment casing forming one or more flow channels, such that during a leak material leaked from the pipeline flows along a predetermined direction within the one or more flow channels. The containment casing prevents movement of the material leaked from the pipeline to an environment external to the casing. The system may further comprise a plurality of sensors to provide notification of the leak to a user device.

    摘要: This application relates to a leak detector device (100) for detecting an internal leak in a fluid path. The leak detector comprises a housing (110) with a flow passage (120) extending through the housing (110), one or more pairs of temperature sensors (130, 140) for detecting a temperature difference between an outside of the housing (110) and the flow passage (120), one temperature sensor of each pair being arranged towards an outer surface of the housing (110) and the other temperature sensor of the pair being arranged towards an innersurface of the housing (110) that faces the flow passage (120), and an array of electrically conductive wires (150, 160) that extend across the flow passage (120). The array of electrically conductive wires (150, 160) comprises one or more positive polarity wires and one or more negative polarity wires. The application further relates to a corresponding method of leak detection.

    摘要: A gas leak detector providing an improved detection of any leaking LPG (Liquid Petroleum Gas) container. There is disclosed a gas leak detector (100) for detecting a leak of gas from a gas container valve unit (111) and/or a leak of gas between a gas container valve unit (111) and a gas cylinder (104) and/or a leak of gas through a wall or a joint in the gas container (104). The gas leak detector has a housing (106), which can be moved relatively to an external surface (107). The housing (105) has a top part (112), a bottom part (114) and a side part (113), the top part (112) and the bottom part (114) can be movable relative to each other. The gas leak detector (100) further has an air flow generator (160) for providing and moving a mixture of air and any leak of gas within a closed loop for improving detection of a gas leak.

    摘要: Composite sensors that exhibit four deformation modes decoupled from each other are disclosed. The modes include tension, compression, bending, and torsion. In one exemplary embodiment, the sensor includes a substrate and six unit sensors. The unit sensors are paired such that each pair includes two unit sensors disposed on opposite surfaces of the substrate, the sensors being substantially opposed to each other. Two of the pairs include longitudinal axes that are substantially parallel to each other, and the third pair includes a longitudinal axis that is substantially perpendicular to the other two longitudinal axes. The substrate is constrained along one of its edges. The composite sensors can be used in many contexts, such as part of a flow- driven, soft robot that passes through a pipe and detect links. Methods of detecting leaks are also described.

    摘要: Water leak detection to protect flight critical equipment from failed water distribution lines. The system uses a reference sensor and an additional sensor in order to measure voltage across a circuit when both sensors are in contact with a conductive fluid. The system also provides a water shut off protocol that can protect the equipment from a leak during flight, while allowing unaffected galleys and lavatories to remain functional.

    摘要: The present application provides an apparatus comprising a radio frequency identification (RFID) sensor comprising: an antenna configured to receive an interrogation signal from a reader and to transmit a response signal to the reader; at least one integrated circuit (IC) connected to the antenna; and at least one sensing element. The apparatus further comprises a channel for directing transmission of signals between the antenna and the reader, wherein the RFID sensor is attached or directly adjacent to a first end of the channel. The sensing element is responsive to a change induced by its environment to switch from a conductive state to a non-conductive state, or from a non-conductive state to a conductive state. The present application further provides a method for monitoring the integrity or the change in environment of a buried structure using the RFID sensor-containing apparatus.
