A method for electrically activating a measurement stand with a movement of at least one measuring probe (26) from a starting position (31) into a measuring position (32) and also a measurement stand for supporting a measuring probe, in particular for measuring the thickness of thin layers, in which a motor (34) is activated by a control arrangement (25), which moves a ram (23) up and down via a drive arrangement (35), wherein a retainer (24) is provided on the ram (23), to which retainer the measuring probe (26) can be fastened, in which a freewheel is activated between the drive arrangement (35) and the ram (33) as soon as the measuring probe (26) or retainer (23) is set down in the measuring position (32) on an item to be measured (14) and the movement of the drive arrangement (35) is decoupled from the vertical movement of the ram (23), wherein a movement speed of the at least one measuring probe (14) from the starting position (31) into the measuring position (32) is reduced by mechanical damping or electrical damping before the measuring position (32) is reached.

A headlamp aiming tool includes a linear member and four legs, the first of which is connected with one end of the member and the second, third and fourth of which are adjustable relative to the linear member. The first and second legs of the tool are used to measure the distance between the headlamps of a vehicle and the height of the headlamps relative to the ground or floor. The tool may also be mounted on the vehicle via the first and second legs and a fastener connected with the third leg arranged between first and second legs. Lastly, the tool includes a laser device connected with the fourth leg which is also between the first and second legs. The laser device can be aligned with a centerline of the vehicle to direct a laser beam against a screen in front of the vehicle to indicate the vehicle centerline on the screen. The headlamp light and spacing measurements are used to provide headlamp center points on the screen and to determine the horizontal and vertical offset of the low beam light from each headlamp. The offset is used to adjust the headlamps so that they are properly aimed.

Method and system is described to enhance operations for managing the hydrocarbon release. The system utilizes an airborne detection device equipped with measurement components and communication components. The system may utilize various measurement techniques to determine the thickness of the oil slick. This remote detection method may provide a dedicated airborne detection device for each response vessel and that can identify the location and thickness of the oil slick.

The height measuring device is movably positioned on a scale surface, the height measuring device comprises: a bracket repeatedly attached to or detached from the scale surface; and a measuring unit assembled with the bracket, wherein the measuring unit includes a folding position and an extending position relative to the bracket, the measuring unit is close to the bracket in the folding position, and the measuring unit is perpendicular to the scale surface in the extending position. Then, it is convenient to accurately measure the height of users at kinds of objects with a scale surface.

A milling machine includes a milling rotor, at least one leg, a grade sensor, and a control circuit. The milling rotor is configured to engage a surface beneath the milling machine. The at least one leg is controllable to raise and lower the milling machine. The grade sensor is configured to sense a position indicative of a cut depth of the milling rotor, and the control circuit is configured to receive data from the grade sensor. The control circuit is also configured to: identify a distance from the milling rotor to the surface based on a selected position of the at least one leg; identify a value associated with a detected condition using the grade sensor while the at least one leg is at the selected position; and calibrate the grade sensor by associating the identified distance from the milling rotor to the surface and the identified value.
