Abstract: For traffic routing in a walking zone in public buildings, complexes of buildings and traffic zones, which have a plurality of destinations interconnected by traffic routes there are arranged along the traffic routes continuous visual orientation lines which each are associated to one destination, end at the associated destination and can readily be distinguished from each other. The orientation lines are equipped with univocal indicator features pointing towards the associated destination. It is preferably effected by remote control that the orientation lines are composed of display devices which are selectively activated in sections. Remote control is performed in particular by a central control center via a network to which also the control units are connected, which activate the display devices.

Abstract: The concentration of substrates of enzyme reactions is measured by determining the current produced at an platinum or gold electrode by oxidizing an acceptor utilizing a measuring device comprising a measuring cell, an enzyme electrode in contact with the fluid sample and containing an platinum or gold electrode, an enzyme layer and a reference electrode in contact with the fluid sample. In this manner important physiological parameters, such as the concentration of lactate and glucose in fluid biological samples, can be measured quickly and accurately.
