Devices, systems and methods for leak detection are provided herein. Also provided are devices, systems and methods for monitoring and/or measuring fluid usage. In some aspects, a system comprising a sensor, a processing system, and a platform are provided. In some aspects, the sensor may be coupled to a spinning device. The sensor can be configured to detect fluid data, which can comprise, for example, displacement data of liquid and/or movement data associated with the liquid in a container and/or flow data associated with a flow of fluid in a conduit. The processing system can be coupled with the sensor and configured to communicate the fluid data. The platform can comprise an application communicatively coupled to one or more databases storing evaluation data (e.g., known pattern data) and configured to receive the fluid data and determine if there is a leak.

A water heater includes a tank assembly that defines an insulation cavity between an inner storage tank and an outer jacket. The water heater includes a bottom pad that supports the tank assembly thereon. The bottom pad is disposed in a bottom pan. Gaskets are disposed between the bottom pad and the bottom pan of the water heater. The bottom pad and at least one of the gaskets include apertures that are configured to internally route a leak sensor assembly of the water heater from the bottom pan to a controller of the water heater through the insulation cavity while preventing a leak of insulation material from the insulation cavity to the bottom pan. The water heater also includes a mounting bracket that is coupled to the inner storage tank to securely hold and route a portion of the leak sensor assembly disposed in the insulation cavity to the controller.

Systems, methods, and computer program products for infrared (IR) image operations are provided. An example imaging system includes a first IR imaging device configured to generate first IR image data and a second IR imaging device configured to generate second IR image data. The system further includes a computing device that receives the first IR image data from the first IR imaging device and receives the second IR image data from the second IR imaging device. The computing device further determines a first feature representing a position of a gas plume based upon the first IR image data and a second feature representing a position of the gas plume based upon the second IR image data and determines a disparity between the first and second features. The computing device further determines a distance between the imaging system and the gas plume based upon the determined disparity.

An assembly is provided for an aircraft. This aircraft assembly includes a fuselage and a second system. The fuselage includes a wall and a hatch configured to close an opening in the wall. The sensor system includes an optical fiber, a transmitter and a receiver. The optical fiber is arranged at an interface between the hatch and the wall. The transmitter is configured to transmit first electromagnetic radiation into the optical fiber. The receiver is configured to detect second electromagnetic radiation received from the optical fiber to provide receiver data. The sensor system is configured to detect fluid leakage across the interface between the hatch and the wall based on the receiver data.

The present technology is generally directed to assembling and testing ampoules, and associated systems, devices, and methods. Each ampoule can include a body portion configured to carry a marking material within an interior of the body portion, and a base portion configured to couple to the body portion to seal the interior of the body portion. The ampoules can be assembled and/or tested in an inverted orientation. In the inverted orientation, the ampoule can include a gap between the marking material and the base portion. For example, the ampoule can be positioned within a leak detection system and the ampoule's gap can be aligned with one or more leak detection components configured to analyze the gap for leak-related indicia.

A facility-equipment temperature control system allows for controlling the surface temperature of the facility equipment at a low cost and reduction in workload. The facility-equipment temperature control system includes a non-fixed image-capturing device and an image-processing device. The image-capturing device captures the image of the surface of facility equipment to obtain a visible image and a thermal image. Based on the shape information of the common reference part existing in the first visible image and the second visible image, the image-processing device sets a comparison area at the same position and in the same range on the first visible image and the second visible image. In addition, the image-processing device corrects the deviation of the field angle in the comparison area of the first thermal image and the second thermal image and displays the temperature-difference-information, which was obtained by comparing the corrected thermal images on the display screen.

Mechanical, electronic, algorithmic, and computer network facets are combined to create a highly integrated advanced gas sensor. A sensor is integrated into switchgear housings. These sensors integrated into high voltage switchgear products, deployed by electric utility end users in replacement and expansion cycles, function to detect and mitigate atmospheric pollution caused by leaking SF.sub.6. As its associated gas insulated tank is charged with 10 to 350 lbs. of SF.sub.6, each gas sensor monitors its local cache of gas, accurately sensing and computing fractional percentage losses (emissions) and gains (maintenance replacement) in SF.sub.6 mass, storing data in onboard data logs, and communicating data when triggered by detection events or in response to remote requests over a hierarchical communications network, a process that continues without labor until a fractional leak is automatically detected and reported creating the opportunity for early leak mitigation.

The present invention provides a method for leakage testing of an electrostatic chuck. The method for leakage testing of an electrostatic chuck comprises: a mounting step of mounting the electrostatic chuck on a test stage of a testing chamber; a loading step of loading a dummy substrate in an upper surface of the electrostatic chuck; a decompression step of decompressing an interior of the testing chamber; a tracking fluid supply step of supplying a tracking fluid with visibility to a flow path of the electrostatic chuck; a photographing step of photographing the electrostatic chuck; and a determination step of determining whether a leakage occurs in the flow path by examining an image photographed in the photographing step.

Example aspects of a thermal monitoring system are disclosed. The thermal monitoring system can comprise a cryogenic storage container comprising an external wall and an internal wall, wherein a cold cryogenic liquid is housed within the internal wall, and wherein a vacuum is formed between the external wall and the internal wall; a thermal imaging camera configured to measure temperatures within a region of interest, wherein the cryogenic storage container is oriented within the region of interest and the thermal imaging camera measures an external temperature of the outer wall of the cryogenic storage container, the thermal imaging camera further comprising camera software configured to generate a thermographic video of the external temperature; a display device displaying the thermographic video; and an alarm unit configured to activate an alert when the external temperature of the cryogenic storage container drops below a pre-selected trigger temperature.
