摘要： An apparatus for electrochemically determining the partial oxygen pressure pO.sub.2 in a liquid measuring medium includes a measuring sensor having a working electrode and a counter-electrode. The electrodes are manufactured in thin-film technology and are arranged on a substrate in a measuring channel, to which the measuring medium and a rinse medium can be supplied in alternation. The measuring channel connects a device which controls the flow rate of the measuring medium to a lumen of a double lumen catheter. The rinse medium is suppliable to a second lumen of the double lumen catheter with reversible flow direction. Both lumens have a common orifice which can be introduced into the measuring medium. So-called poisoning of the electrodes in this arrangement is suppressed because the electrodes are flooded in alternation by the measuring medium in a measuring phase and by the rinse medium in a regeneration phase.

摘要： A measuring canal is provided which is connected to a catheter. The canal includes a measuring sensor and a reference sensor. The catheter includes several lumens that have a common opening to the liquid measuring medium. The flow direction of an infusion solution at the opening is reversible. A second lumen of the catheter is connected to the measuring canal which is provided with at least one measuring sensor and with at least one reference sensor as well as with a device for setting the outflow of the apparatus to a predetermined velocity. The flow of an infusion fluid and the liquid medium alternates in such a fashion that during a first time interval the measuring sensor is coupled to the liquid medium and the reference sensor is coupled to the infusion solution. In a second interval the situation is reversed so that the original measuring sensor is coupled to the infusion solution and the original reference sensor is connected to the liquid medium. The unique arrangement is effective for blood examination. Drift problems and toxicity problems cannot occur and no electrochemical reference electrode is required.

摘要： A radio-interrogated, surface-wave technology current transformer for high/medium-voltage systems includes a magnetosensitive element connected to a surface-wave structure of a surface-wave configuration as a termination of the surface-wave structure. A response signal of the surface-wave configuration is information regarding current strength/direction and phase of the current instantaneously flowing through the system, which is evaluated by a ground station. By virtue of the radio transmission, there is no electrical insulation problem, and the use of a radio-interrogated surface-wave configuration makes that part of the overall current transducer which is at high potential into a passive element of the same.

摘要： A device for determining the angular position of an object uses an MR sensor which is set up in a magnetic field, where one magnetic field component (H or H.sub.g) and a reference axis of the MR sensor can rotate relative to one another in a plane of rotation through an angle of rotation (.THETA. or .phi.) which has an unambiguous correlation to the angular position of the object; and the electric resistance of the MR sensor is an unambiguous function of this angle of rotation (.THETA. or .phi.). The MR sensor is designed with a giant MR layer system that contains at least one measurement layer with magnetization (M.sub.M) that can be rotated through the magnetic field (H or H.sub.g); the giant MR layer system also contains at least one biasing layer with a constant magnetization (M.sub.B); and the resistance of the giant MR layer system is a function of the angle (.alpha.) between these two magnetizations (M.sub.m and M.sub.B).

摘要： The magnetizations of the bias-layer parts of several sensor elements interconnected to form a bridge are to be set using the present device. These sensor elements are arranged on a common substrate and display an increased magneto-resistive effect. The present device has several conductive-track parts in such an arrangement that, with a predetermined position of the conductive-track parts with respect to the sensor elements of the bridge circuit, in each case one conductive-track part is associated with at least one sensor element. A set current of a predetermined direction and strength is conducted over each conductive-track part in such a manner that a predetermined direction of orientation of the magnetization can be set in fixed manner in the bias-layer part of the corresponding associated sensor element.
