Abstract: A method for determining the portion of an electrochemically detectable substance in a gas sample includes the steps of introducing the gas sample into an electrochemical measuring cell 1 and generating a measurement curve i(t) by the electrochemical conversion of the substance in the measuring cell 1. The measuring curve i(t) increases from a reference line to a maximum value i.sub.max and drops back again to the reference line. Then, the maximum value i.sub.max and an area A below the measuring curve i(t) are determined. The area A is proportional to the portion of the substance in the gas sample. The method is improved in that a new measurement value is made available after a short time. This is achieved in that the maximum value i.sub.n max and the area A.sub.n of a previous measurement are compared to each other and a proportionality factor K.sub.n is determined. The proportionality factor K.sub.n is given by the ratio of the area A.sub.n to the maximum value i.sub.n max and, for a new measurement, a new maximum value i.sub.n+1 max is determined and the portion of the substance in the gas sample is computed for the new measurement from the new maximum value i.sub.n+1 max and the proportionality factor K.sub.n of the previous measurement.

Abstract: The invention is directed to a measuring cell for an electrochemical gas sensor having an electrolytic chamber and a measuring electrode as well as a counter electrode. In the direction facing the ambient, the measuring electrode includes a diffusion membrane as well as a diffusion barrier. The diffusion barrier is made of a material which is a good conductor of heat and is provided with a plurality of passages. A temperature-sensitive element is provided in the immediate proximity of these passages and faces toward the ambient. With this configuration, the temperature dependency of the diffusion capacity of the gas sample passing through the diffusion barrier can be included in the processing of the signal indicative of the measurement.

Abstract: The invention is directed to an apparatus for sensing a gaseous component in air and includes a housing having a flushing chamber through which an air sample can flow via a closeable inlet and a closeable outlet. The sensor is mounted in a measuring chamber above the flushing chamber and is hermetically sealed from its ambient not only during the time that the flushing chamber is flushed with the air sample; rather, and most important, during the measuring operation itself in order that any influences from a diffusion of the ambient air into the measuring chamber is prevented. For this purpose and to determine the sample quantity diffusing into the measuring chamber at the beginning of a specific period of time, the inlet as well as the outlet of the flushing chamber is closed while at the same time the diffusion passage interconnecting the two chambers is opened. After the time period has run, the diffusion passage is again closed.

Abstract: The invention is directed to an arrangement for blocking the operation by an intoxicated operator of a machine or a motor vehicle. The arrangement has a measuring apparatus which determines the blood alcohol content of the operator and an evaluation unit connected to the machine or motor vehicle. The evaluation unit receives measurement data supplied by the measurement apparatus and enables the machine or motor vehicle when the measurement data satisfies at least one predetermined condition. The arrangement is improved in that the sobriety of the operator is recognized before the starting operation of the machine or motor vehicle without it being necessary to supply a breath sample. The measuring apparatus includes a gas sensor which is a sensor for measuring the blood alcohol content via permeation through the skin of the operator. The measuring apparatus is configured so that it can be worn by the operator preferably on the leg or arm.

Abstract: A closed cycle respirator is disclosed which includes a respiration air cycle having a breathing bag and a carbon dioxide absorber with connecting lines between the breathing bag and absorber and to a junction adapted for use by the user of the equipment. A pressurized oxygen bottle is provided with a controllable valve for supplying oxygen to the cycle in case the oxygen drops below a selected value in the breathing bag. In case of failure of the controllable valve, a separate oxygen supply connection is provided to the breathing cycle with a valve which senses a reduction of pressure in the breathing cycle and opens the connection to the oxygen bottle for emergency supply of oxygen to the cycle.
