Abstract: The present invention relates to an online mind-altering substance testing system. The system includes distributed mind-altering substance testing units for performing mind-altering substance tests. A server is provided for receiving results of the mind-altering substance tests. A database is provided for storing the results. A display is provided for displaying the stored results, preferably in a dashboard of graphs to facilitate rapid and intuitive evaluation of often large numbers of tests from various testing units. Advantageously, a reviewer may review live stored results from multiple testing units once the tests have been performed, which enables rapid risk assessment and corrective action to be undertaken. For example, the effect of failed tests may be more frequent at a certain site prompting a need for investigating a cause at that site.

Abstract: An operating device for operating at least one Hg low-pressure discharge lamp which has a first and a second electrode coil may include a unit for providing a variable that is correlated with the Hg vapor pressure in the at least one Hg low-pressure discharge lamp comprises at least one unit for capturing emission spectra of at least specifiable spectral ranges, wherein the unit for capturing emission spectra may include at least one light receiving unit which is arranged in the beam path of the at least one Hg low-pressure discharge lamp.

Abstract: A lamp envelope is provided with an alumina layer and a multilayer phosphor coating on the alumina layer. The phosphor coating includes a top phosphor layer with a first weight percent of rare earth activators and a middle phosphor layer with a second weight percent of rare earth activators. The second weight percent is less than the first weight percent so that a total amount of the activators in the coating is reduced while maintaining a required lamp brightness and color rendering index (CRI). Preferably, the second weight percent is about 50-60% of the first weight percent and the middle layer is about 30-50% of a total weight of the coating so that a total weight of the activators in the coating is no more than about 80% of a weight of the activators in the coating if the first and second weight percents were the same.
