Abstract: A spray head (1) for a water faucet (2) having a water inlet (3), and at least one first water outlet (4), one second water outlet (5) and one changeover valve (6) for selectively activating a first water-conducting connection (7) from the water inlet (3) to the first water outlet (4) or a second water-conducting connection (8) from the water inlet (3) to the second water outlet (5), wherein the changeover valve (6) is connected to a setting means (9), which has a push button (10) and which is designed such that an actuation of the push button (10) makes it possible to change from the first water-conducting connection (7) to the second water-conducting connection (8) and vice versa.

Abstract: A vehicle surface analysis system includes a vehicle positioning unit, an optical image acquisition unit and an evaluation unit. The vehicle positioning unit includes a rotatable platform for supporting a vehicle. The image acquisition unit includes a plurality of individual image acquisition units, which operate with different wavelength work spectra and radiation energy levels to generate a number of recorded mages. The evaluation unit includes a difference value generation module, a difference value assessment module, an overall assessment module, and a generation module. The evaluation unit is constructed to provide a digital surface condition image of the vehicle.

Abstract: A laser scanning microscope (LSM) having variable light intensity and a control method for the same. The light intensity of a laser beam in an LSM has been controlled to date with high accuracy, but also high costs by means of an acousto-optic component (AOM, AOTF). According to the invention, such a component for beam modulation is to be omitted, without reducing the exposure accuracy of the sample. In an LSM, a directly modulated laser diode (10) is used with an electric control (12) for direct modulation. Said laser diode (10) has a turn-on delay of the light intensity that is dependent on the amount of the control variable when subjected to an electric control variable. The control (12) is designed such that the fluctuation width (??tV) of the occurring turn-on delay (?tV) is smaller than 1 ?s, particularly smaller than 0.5 ?s. Thus highly exact modulation without an acousto-optic component is possible.
