A leakage detection system is provided and includes a substrate provided between a first element and a second element, and at least one sensing unit provided on the substrate to generate an electrical signal when coming into contact with a leakage liquid. As such, warnings can be provided when coming into contact with the leakage liquid to avoid significant loss of assets.

An apparatus comprising a sleeve. The sleeve has an outer surface and a flange extending from the outer surface. The flange has a first surface for engaging an edge of first flexible hose and a second surface for engaging a union. The first surface of the flange has a radial length substantially equal to a thickness of the edge of the first flexible hose. The sleeve counteracts a deflection of the first flexible hose and the second flexible hose into a flow path created through the first flexible hose and the second flexible hose when the first flexible hose and the second flexible hose are coupled together using the union, the sleeve, and a pair of fittings.

A hose connector has: a cap, a connecting pipe and an assembly pipe. The cap has an inner ring and an outer ring, and the inner ring is provided with an inner threaded hole. The cap further has a socket hole connected with the inner threaded hole, the outer ring is provided with an outer threaded section. The connecting pipe has an inserting portion at one end and a first threaded portion at another end. The inserting portion has a neck section and a stopping ring. The inserting portion is disposed in the socket hole of the cap. The stopping ring comprises at least one protrusion facing the groove. The assembly pipe has a through hole and a convex ring at one end and a second threaded portion at another end. The second threaded portion of the assembly pipe engages with the inner threaded hole of the cap.

An adapter for putting two incompatible medical systems in fluid communication with each other. The adapter may have a continuous outer diameter and may include two segments: a first segment composed of a rigid material and including a first portion and a second portion, the first portion having a continuous outer diameter and the second portion defining one or more flanges, the first segment defining a first passage therethrough; and a second segment composed of a flexible material and coupled to the first segment, including a first portion and a second portion. The first portion of the second segment may have an inner surface configured to surround the flanges of the second portion of the first segment, and the second portion of the second segment having a tapered inner surface, the second segment defining a second passage therethrough that is continuous with the first passage.

Vacuum adapter apparatus, systems, and related methods for use with inflatable structures having relief valves are disclosed. An example vacuum adapter for a relief valve of an inflatable structure includes a first end portion adapted to connect with the relief valve, a second end portion adapted to connect with a vacuum fluid line, an intermediate portion coupled between the first and second end portions, a vacuum chamber extending through the intermediate portion between the first and second end portions such that a fluid is conveyable through the vacuum chamber from the relief valve to the vacuum fluid line, and a fluid seal positioned on the first end portion. The fluid seal is configured to engage an outlet portion of the relief valve to maintain a negative gauge pressure in the vacuum chamber that causes the relief valve to open during a deflating process of the inflatable structure.

A modular kinematic and telemetry system for an irrigation system includes a condition-based monitoring (CBM) system and a plurality of sets of modular foot assemblies. The CBM system has a housing and supports a plurality of kinematic and telemetry components. The plurality of sets of modular foot assemblies includes a first set and a second set that secure to the housing of the CBM system. The first set is configured to secure the CBM system to a first end gun configuration and the second set is configured to secure the CBM system to a second end gun configuration that is different from the first end gun configuration.

A pet watering system. The pet watering system includes a housing and a waterspout. The waterspout is connected to a water source and is configured to allow water to stream from the water source to the exterior of the housing. The pet watering system also includes a trough, where the trough is configured to receive water that has streamed from the waterspout. The pet watering system further includes a proximity sensor, where the proximity sensor is configured to allow a pet to control the flow of water from the reservoir to the waterspout.

An end-fitting and an unbonded flexible pipe, where the unbonded flexible pipe includes from the inside and out an internal pressure sheath, at least one armor layer and an outer sheath, the end-fitting further includes a sealing element. The sealing element includes a seal casing concentrically arranged around the internal pressure sheath, the seal casing includes a recess in which a first sealing element is concentrically arranged around the internal pressure sheath such that the surface of the first sealing element at least forms a line contact with the internal pressure sheath, and a second sealing element is concentrically arranged around the internal pressure sheath in the recess such that the surface of the second sealing element at least form a line contact with the surface of the seal casing and form a line contact with the surface of the first sealing element.

A garden hose has an inner tube for conveying water at domestic water pressure from a first coupler disposed at a first end of the inner tube to a second coupler disposed at a second end of the inner tube, the inner tube being waterproof and flexible, the first coupler adapted to threadedly connect to a conventional water faucet and the second coupler adapted to threadedly connect to a conventional garden appliance. The hose has a metal sheath disposed over the inner tube and extending from the first coupler to the second coupler, the flexible metal sheath having a first shoulder near the first coupler and a second shoulder near the second coupler, the metal sheath being flexible, and a fabric sheath disposed over the metal sheath and fixed to the metal sheath by a first constricting band disposed at the first shoulder and a second constricting band disposed at the second shoulder.
