Abstract: A system for determining the characteristics of a gas is described, comprising at least one beam of coherent and monochromatic light, detecting means of scattered light comprising at least one photo-detector, at least one measuring chamber within which the beam and the detecting means are operating, and control means operatively connected to the photo-detector for recording an amount of scattered light according to the Rayleigh scattering principle depending on the physical characteristics of the gas molecule and on a wavelength of the coherent and monochromatic light, the beam of coherent and monochromatic light being emitted by at least one laser with continuous wave. A method for measuring the characteristics of a gas through such system is further described.

Abstract: A system (1) for determining the characteristics of a gas is described, comprising at least one beam (10) of coherent and monochromatic light, detecting means (20) of scattered light comprising at least one photo-detector (21), at least one measuring chamber (30) within which the beam (10) and the detecting means (20) are operating, and control means (40) operatively connected to the photo-detector (21) for recording an amount of scattered light according to the Rayleigh scattering principle depending on the physical characteristics of the gas molecule and on a wavelength of the coherent and monochromatic light, the beam (10) of coherent and monochromatic light being emitted by at least one laser (11) with continuous wave. A method for measuring the characteristics of a gas through such system (1) is further described.

Abstract: An apparatus is for a scope assembly having a front scope section and a back scope section, and a firearm including a mounting rail having a front rail section and a back rail section. The apparatus includes a front scope guard frame configured to guard, at least in part, the front scope section of the scope assembly. A back scope guard frame is configured to guard, at least in part, the back scope section of the scope assembly. The front scope guard frame and the back scope guard frame are selectively positionable and movable, independently of each other, relative to the mounting rail. The front scope guard frame and the back scope guard frame are configured to selectively affix, independently of each other, once the front scope guard frame and the back scope guard frame are positioned just so.
