Presented herein are systems, methods, and apparatus related to relocatable tower technologies that facilitate on-site deployment and provide improved stiffness in order to minimize motion at a tower top in a manner that existing approaches, which focus on survivability, do not contemplate. In particular, relocatable tower technologies described herein can be deployed rapidly and at low cost, at outdoor sites, to, e.g., provide a vertical mast upon which equipment can be mounted. In certain embodiments, features of relocatable towers described herein allow the vertical mast to survive and remain rigid while being exposed to outdoor elements, such as wind gusts (e.g., up to 110 Mph). Advantages of relocatable tower technologies described herein are particularly well suited where (e.g., scanning based) imaging and/or detection equipment is mounted at a top of the tower, and/or where towers are deployed at sensitive sites such as hydrocarbon production, storage and processing facilities.

Presented herein are systems and methods directed to a multispectral absorption-based imaging approach offering improved detection, localization, and quantification of gas emission. The imaging technology described herein utilizes an optical sensor and broadband illumination in combination with specialized reflector installments mounted about the site. The optical sensor detects light (e.g., reflected) from locations along the reflector installment. Lines-of-sight from the optical sensor to locations along the reflector installment sweep out an 'optical curtain' partially enclosing and/or forming a boundary near various assets to be monitored. Optical absorption signatures from leaking gas crossing the optical curtain can be used to detect, localize, and obtain quantitative measures characterizing the leak. Measurements from reflector installments can be combined with measurements obtained via reflection of ambient light from background materials in a hybrid approach that expands monitoring capabilities and offers improvements in detection.

Systems and methods for leak monitoring via measurement of optical absorption using tailored reflector installments

Presented herein are systems and methods directed to a multispectral absorption-based imaging approach that provides for rapid and accurate detection, localization, and quantification of gas emission from within a site to be monitored. The imaging technology described herein utilizes an optical sensor and broadband illumination in combination with specialized reflector installments mounted about the site. The optical sensor detects light (e.g., reflected) from a plurality of sampled locations along the reflector installment, for example by imaging multiple sampled locations at a time and/or scanning an instantaneous field of view (ifov) of the optical sensor. Lines-of-sight from the optical sensor to sampled locations along the reflector installment sweep out an 'optical curtain' partially enclosing and/or forming a boundary near various assets to be monitored. Optical absorption signatures from leaking gas crossing the optical curtain can be used to detect, localize, and obtain quantitative measures characterizing the leak.

Presented herein are systems and methods directed to a multispectral absorption-based imaging approach that provides for rapid and accurate detection, localization, and quantification of gas leaks. The imaging technology described herein utilizes a scanning optical sensor in combination with structured and scannable illumination to detect and image spectral signatures produced by absorption of light by leaking gas in a quantitative manner over wide areas, at distance, and in the presence of background such as ambient gas and vapor. Moreover, the specifically structured and scannable illumination source of the systems and methods described herein provides a consistent source of illumination for the scanning optical sensor, allowing imaging to be performed even in the absence of sufficient natural light, such as sunlight. The imaging approaches described herein can, accordingly, be used for a variety of gas leak detection, emissions monitoring, and safety applications.

A gasket for a compressed gas cylinder arranged to operate with a gas cylinder having a neck with a top surface around a gas outlet and a side surface extending downwardly from the top surface. The gasket may include an upper portion arranged for positioning on the top surface of the cylinder and for making a seal with the top surface, and a lower portion extending downwardly from the upper portion and around the side surface of the neck of the cylinder, such that the lower portion is arranged to make a seal with the side surface of the gas cylinder. Face and gland seals may be established by the gasket with an opening that receives the gasket and an associated cylinder neck.

Sound bar audio speaker

Acoustic transducers may, in certain aspects, include a curved diaphragm and an actuator coupled to the curved diaphragm to cause movement of the curved diaphragm. In certain embodiments, the curved diaphragm has at least one free edge. The left and right edges of the curved diaphragm may be associated with auxiliary supports. The acoustic transducer can be a multi-pole loudspeaker wherein a curved diaphragm radiates the sound energy in a modified dipole pattern. The curvature of the radiating surface of the transducer reduces sound cancellation from sound energy reflected by nearby surfaces.

A disposable differential pressure pneumotachometer includes an inlet chamber having an air inlet, an outlet chamber having an air outlet, and a resistive element disposed between the inlet and outlet chambers. Air flow across the resistive element results in a pressure gradient which is measured to provide air flow rate. According to one aspect of the invention, the pressure port through which the static pressure in the inlet chamber is sensed is disposed in the outlet chamber. According to a further aspect of the invention, the resistive element comprises a bacterial filter material. Also described is a pneumotachometer in which at least one pressure port is covered with a bacterial filter material.
