A method for detecting a hot target on the Earth by a satellite is disclosed. The satellite includes a sensor for acquiring data in spectral channels in the IR spectrum, and a navigation system for detecting position and orientation data of the satellite. The method includes the steps of subjecting the acquired data to a system correction by radiometric and geometric calibration files stored on the satellite; detecting a hot target on board from the system-corrected data by multi-channel thresholding; geo-referencing the hot target by the position and orientation data of the satellite and the geometric calibration files; temporarily storing the geo-referenced hot target on the satellite; and transmitting the temporarily stored hot target by a transmitting unit to a receiving unit on the Earth.

A process and a device for the joining of fastening elements on a mask frame of picture tubes by welding using laser beams is applicable to the production of color picture tubes for television sets and computer monitors. After positioning the fastening elements, the elements are welded by laser beams from at least one laser source. The laser source is located outside the mask frame, and the laser beam is guided through a glass wall of a screen to weld the fastening elements.
