A system for airborne remote sensing comprises an array of remote sensing devices configured for being towed by an aircraft. Each of the array of remote sensing devices is configured for lateral separation in flight, to provide a large coverage area than any of the array of remote sensing devices can cover by itself. Onboard electronics comprise sensors, such as a forward imaging infrared camera for capturing data in flight. By analyzing the data collected by the remote sensing system, various types of information can be generated, such as hydrocarbon leak detection.

A UAV-carried surveillance and remote sensing platform is launched from a high altitude and flies over a target area, collecting remote sensing imagery before returning to earth. The UAV may be towed to a desired altitude by a powered aircraft or a balloon and then launched for cruising over a target area while capturing data. Instead of being piloted remotely, the UAV employs an autonomous flight control system.

A system for airborne remote sensing comprises an array of remote imaging sensors and supporting equipment configured for a combined larger field of view and provided by any of the array of remote imaging sensors alone. The array is mounted in a housing for attachment to a wing or elsewhere on an aircraft. Data collected by the array may be stitched together to provide an image of a larger area than can be acquired by any one of the remote imaging sensors. The data may be stored onboard the aircraft or transmitted to a ground receiver for analysis. The array of remote imaging sensors thus allows for more effective use of an aircraft for activities such as hydrocarbon leak detection and pipeline right-of-way monitoring.

Systems and methods for adjusting operation of a train are disclosed. A method may include: receiving one or more infrared images of a brake line of the train; detecting one or more leaks of the brake line based on the one or more infrared images; and adjusting a brake command based on the detected one or more leaks.

A method of testing for leaks within substantially the entirety of a piping system of a building or a section thereof. The method comprises isolation of a main of the piping system and removal of the building fixtures. Optionally, a line trace and/or a dye test may be implemented. The method further comprises purging the piping system to at least partially reduce or eliminate entrapped air. The method further comprises sealing the plumbing outlets of the piping system and filling the piping system up to a predetermined elevation above a highest fitting connection or up to the highest serviceable point of the system. The method further comprises inspecting the piping system for leaks after a predetermined period of time, which may be anywhere from immediately after filling the piping system to about twenty minutes thereafter.

A sensor for determining a liquid type, includes: a plano-convex lens; a lens holder configured to support the plano-convex lens via an edge of the lens; an outputting optical fiber that abuts against a plane surface of the plano-convex lens to output light; a light-receiving optical fiber that abuts against the plane surface of the plano-convex lens to receive light; a light-emitting unit connected to the outputting optical fiber; and a light amount measuring unit connected to the light-receiving optical fiber to measure a light amount. The outputting optical fiber is provided so that an end face of the outputting optical fiber is disposed on the edge of the plano-convex lens, and preferably, a central axis thereof at the end face thereof passes through the plane surface of the plano-convex lens.
