An airborne measurement system with an onboard computer for data processing and recording that does not require constant radio communication for inspection and maintenance is presented. It detects, locates, and quantifies methane leaks using a gimbal-mounted sensor. A model that correlates wind speed with drone attitude is presented and compared to measurements made with an anemometer. The quantification of methane emissions was evaluated in a laboratory setup and at an open-area test site.

This paper examines the new study of hand orientation as a substitute for computer-mouse movement and is evaluated based on ISO/TS 9241 part 411:Ergonomics of human–system interaction. Two pairs of hand-orientation candidates were evaluated, pitch–roll and pitch–yaw, to substitute up–down and left–right mouse-cursor movements. The empirical findings in this study provide a new suggestion for a suitable level of difficulty when using an inertial sensor to emulate the movement of a mouse cursor.
