Abstract: This invention relates to a device with function for measuring volumetric changes in a substance. In particular, the device with function for measuring volumetric changes in a substance comprises a sensor that detects the amount of light intensity produced by a light source aligned with said sensor when passing through a column of two liquids which are immiscible among each other contained in a transparent tube, wherein the sensor and the aligned light source are mounted on an arm that travels on a vertically arranged rail, wherein the arm is attached to a strap which acts by means of a first and a second pulley causing the movement of said arm, wherein the movement of said pulleys comes from a motor and a gearbox and the entire mobility system is mounted on a frame. The device further comprises data acquisition means which record the change of light intensity and control the arm movement.

Abstract: A visor assembly structured to effectively shade a viewing screen of a monitor of the type utilized in a personal computer or like equipment to the extent of at least partially shading light from a viewing screen of the equipment thereby preventing unwanted glare appearing thereon. The visor assembly is adjustably mounted along an upper periphery of a housing of the viewing screen and adjustable longitudinally to accommodate monitors or screen housings of various sizes and outwardly in angularly overlying relation to the viewing screen for optimum positioning to prevent glare thereon.
