Techniques for implementing and/or operating a system that includes an inner pipe segment disposed within an outer bore and a testing apparatus. The inner pipe segment includes tubing that defines a pipe bore through the inner pipe segment and a fluid conduit within a tubing annulus of the inner pipe segment. The testing apparatus includes a test fluid source fluidly connected to the fluid conduit defined within the inner pipe segment, in which the test fluid source injects test fluid into the tubing annulus of the inner pipe segment, and sensors disposed along the outer bore, in which the sensors determine sensor data indicative of a downstream parameter that results due to injection of the test fluid into the tubing annulus of the inner pipe segment to enable a potential location of a breach in the tubing of the inner pipe segment to be determined based on the downstream parameter.

Methods for testing the integrity of a containment sump in contact with a matrix with a testing apparatus are provided. The testing apparatus may include an underground fixture positioned in contact the matrix, a test chamber, a conduit structure providing fluid communication between the underground fixture and the test chamber, and a pressure source for exerting a pressure that is communicated to the underground fixture via the conduit structure. In some embodiments, a method may include: releasing a test media into the containment sump; generating a negative pressure within the testing apparatus for a time period; and testing for the presence of test media within the testing apparatus. In other embodiments, a method may include: releasing a test media into the testing apparatus; generating a positive pressure within the testing apparatus for a time period; and testing for the presence of test media within the containment sump.

Techniques for detecting a high gas pressure situation within a gas delivery system (e.g., for natural gas delivery to homes and businesses) are described. In one example, a device measures gas pressure. If a pressure over a threshold value is detected, a nearby device is messaged. The nearby device either confirms the over-pressure condition or indicates it may be more localized. If the condition is present within an area of the gas delivery system and/or within a group of devices within the gas delivery system, protective measures may be taken, such as closing valves providing gas to a number of service sites.

A hybrid structure ultraviolet dye for leak detection in an appliance includes a ceramic matrix defining pores, and fluorophores encapsulated in nanoparticles bonded to the ceramic matrix within the pores. Upon excitation, the fluorophores release energy and emit fluorescent light to be detected under an ultraviolet lamp. The hybrid structure ultraviolet dye can be included in the refrigerant of a sealed system such that upon refrigerant, the hybrid structure ultraviolet dye, or both exit the sealed system at a leak onto external surfaces of the components, the color emitted by the fluorophores can be detected via application of a UV light.

The invention concerns the field of container closure integrity (CCI) and the testing of CCI and relates to a device and a method for leakage testing of a connection between a rubber stopper and a corresponding drug container which can be used for storing drugs under sterile conditions and which is closed by said rubber stopper.

An information handling system may include an information handling resource, a liquid cooling system for providing cooling of the information handling resource, and a leak detection system for detecting a leak of fluid from the liquid cooling system, the leak detection system comprising a leak detection circuit having at least one moisture-sensitive portion configured to detect the presence of moisture proximate to the leak detection circuit and circuitry configured to communicate one or more electrical signals indicative of the presence or absence of moisture proximate to the leak detection circuit and a moisture wicking material mechanically coupled to the leak detection circuit and configured to transport moisture within the moisture wicking material to the at least one moisture-sensitive portion of the leak detection circuit.

The current document is directed to a leak-and-sealing-failure-detection sensor and a leak-detection system that incorporates the leak-and-sealing-failure sensor to detect leaks and sealing failures in a variety of different containers, packages, and products. The leak-and-sealing-failure-detection sensor produces a response signal when the leak-and-sealing-failure-detection sensor detects a difference between a local environment associated with the leak-and-sealing-failure-detection sensor and the environment external to the leak-and-sealing-failure-detection sensor and the container, package, and/or product to which the leak-and-sealing-failure-detection sensor is applied.
