A system for remote quantitative detection of fluid leaks from a natural gas or oil pipeline by use of an airborne platform; including at least one laser light source for nearly simultaneous illuminating two or more target fluids and a background, wherein the two or more target fluids are characterized by two or more absorption wavelengths, and wherein the background has a different wavelength than either of the two or more target fluids. The illumination source is pointed based on a positioning system while in a geometric area along a path two or more target fluids are scanned for using the illumination sources. A signal detector detects the two or more target fluids using quantitative signal processing. Also included are a controller, a path planning and path finding tool for the positioning of the airborne platform, and a communicator for communicating the presence of the detected leak.

A key mechanism for actuating a circuit board includes a housing whereon an opening is formed, a key button installed inside the opening of the housing, and a waterproof structure installed between the key button and the circuit board for preventing fluid from leaking into the circuit board via an interface of the housing and the key button. A space is formed between the waterproof structure and the key button for containing the fluid leaking from the interface of the housing and the key button. The space is lower than the interface of the housing and the key button.

A hydraulic hybrid vehicle includes elements such as a hydraulic pump driven by an internal combustion engine and arranged to draw in low pressure fluid and pump the fluid at high pressure to an accumulator. A hydraulic motor is powered by the pressurized fluid. Safety processes are provided for detecting and addressing a number of conditions that may arise in the operation of the hydraulic hybrid vehicle, including an initialization procedure for start-up of the vehicle, a shut-down procedure, and procedures for detecting and responding to failure of the pump or motor, internal and external fluid leaks, and non-responsive actuation and mode control systems.

Disclosed are acid fracturing methods for subterranean siliceous formations employing a viscous dissolving fluid to create a permeable conduit that bypasses the near wellbore damage. The viscous dissolving fluids used according to the invention are acid-fracturing treatment fluids containing a dissolving agent viscosified with a material such as a viscoelastic surfactant, and the fluid is injected into a sandstone formation at a pressure sufficient to create a hydraulic fracture. Also, the viscous dissolving fluid leaks off into the faces of the fracture thus “stimulating” the formation. Hence when the hydraulic fracture has closed there is a part of the formation that has been effectively stimulated, creating a pathway for fluids to preferentially flow to the wellbore. The formation may then be flowed back to produce a substantial volume of the treatment fluid.

Systems and methods are provided for detecting and preventing fluid leaks. A rate of flow of a fluid through a conduit over a period of time is monitored. A determination is made whether the rate of flow of the fluid over the period of time indicates a leak in the conduit. If the rate of flow of the fluid over the period of time indicates a leak, then the flow of the liquid through the conduit is stopped, and a determination is made whether the pressure in the conduit indicates a pressure drop. If the pressure in the conduit indicates a pressure drop, then an indication is provided that a leak has been detected.
