Abstract: An operational assistance method for a vehicle, in particular for a motor vehicle, is provided. A movement of an area of a body of a vehicle occupant is captured and sensor values representative of the movement are provided, sensor values for an area of the body of a vehicle occupant are weighted with one another and are combined to form an acceleration value, and the acceleration value is provided. A weighting factor for a respective sensor value, as the degree of the weighting of the sensor value in the acceleration value, is dependent on the magnitude of the sensor value.

Abstract: A motion sickness mitigation method for the purposes of mitigating motion sickness of a vehicle occupant travelling in a motor vehicle includes moving at least a portion of a backrest, a portion of a seat squab, a portion of a head restraint, a portion of an armrest and/or a portion of a footrest as a function of a detected and/or an anticipated driving situation of the motor vehicle, in each case proceeding from a starting position in at least one spatial direction. The movement is situational on the basis of an actual or anticipated trajectory of the motor vehicle.

Abstract: A system performs image stabilization of a display in a vehicle, in particular a motor vehicle. The system includes at least one display, in particular a monitor, for visualization; at least one sensor, in particular an acceleration sensor; and a computer unit, in particular an on-board computer. The system is designed to detect, by way of the sensor, a shock to the vehicle, in particular as a result of unevenness of the roadway, and to carry out on the basis thereof, a compensation calculation by use of the computer unit and to output a correction signal to the display, in order to stabilize the visualization on the display.

Abstract: A process and a reagent for the determination of ions in fluids, wherein the influence of these ions on the activity of an enzyme is measured. The ions for example are sodium, potassium, calcium, magnesium, manganese, lithium, lead, zinc, copper, iron or other heavy metals or non-metallic ions comprising chloride, bicarbonate, protons, ammonium and substances that give rise to ammonium. The enzymes which are used may be a transferase, a hydrolase, an oxidoreductase or a lyase. An essential feature is a method to exclude interferences by ions by masking the interfering ions with a binding agent.

Abstract: The invention concerns a new 6-phosphogluconolactonase which has an enzyme activity of at least 90% with respect to the initial activity after about 20 hours at pH 7.0 and 20.degree. C. In addition a process is described for the production of the enzyme from Leuconostoc. The enzyme is preferably suitable for the determination of ATP or reaction partners which can be converted into 6-phosphogluconolactone.

Abstract: The present invention provides a stabilized, NAD(P)H-dependent, soluble nitrate reductase of the assimilatory type, characterized by a molecular weight of about 90,000 D in the case of electrophoresis in the presence of sodium dodecyl sulphate and a residual activity after 3 weeks at 35.degree. C. of more than 60%, obtainable by preparing a suspension of the comminuted starting material in tris/tartaric acid buffer (pH 7-8.5), adding soluble polyethyleneimine thereto in such an amount that 10 to 20% of the nitrate reductase activity passes into the precipitation obtained, separating off the precipitate and working up the supernatant according to conventional biochemical methods of fractionation in the above-mentioned digestion buffer, dialyzing the enzyme solution obtained and lyophilizing in a zwitterionic buffer.
