The device is mainly used for protecting a welding area during welding.

The invention relates to a method (2) for detecting leaks in a water pipe network, which comprises: acquiring georeferencing data of a water pipe network and indicative georeferencing data from secondary cosmic radiation measurements carried out in a region of the Earth's surface where said water pipe network extends (block 21); processing the acquired data and generating, from the processing carried out, a georeferencing digital map imaged with the water supply network and soil moisture in the region where said water supply network extends (block 22); and detecting and locating one or more leaks in the water pipe network on the basis of the generated georeferencing digital map (block 23).In particular, the processing of acquired data includes estimating soil moisture in the area where the water supply network extends from indicative data from secondary cosmic radiation measurements carried out in said area, using correction factors for the measurements which take into account: the effects of radial sensitivity and anisotropy of the georeferenced secondary cosmic radiation measurements carried out; values ​​of air humidity, atmospheric pressure and intensity of incident secondary cosmic radiation detected simultaneously with the execution of said measurements in the area where the water pipe network extends or in positions on the earth surface where said measurements are carried out; effects related to the presence of vegetation and / or artificial or natural moisture.

An eyepiece for a head-mounted display includes one or more first waveguides arranged to receive light from a spatial light modulator at a first edge, guide at least some of the received light to a second edge opposite the first edge, and extract at least some of the light through a face of the one or more first waveguides between the first and second edges. The eyepiece also includes a second waveguide positioned to receive light exiting the one or more first waveguides at the second edge and guide the received light to one or more light absorbers.

The present invention is based in part on the present inventors' appreciation that certain sequences within an HIV genome are more likely to successfully detect HIV across a breadth of HIV variants. The ability to detect and / or quantify the presence and / or load of HIV in a subject is important to, among other things, the diagnosis and treatment of infected individuals. The present invention is based, in part, on the discovery of oligonucleotide reagents that detectably amplify sequences from a greater breadth of HIV samples than certain prior reagents and / or that generate amplicons from HIV genomes from which certain prior reagents would not have generated amplicons. Oligonucleotide reagents as described herein provide unexpected benefits in the detection and / or quantification of the presence and / or load of HIV in a subject, and thereby in the diagnosis and treatment of HIV.
