摘要： A measurement device for frequency control of a heart pacemaker based on the level of blood oxygen saturation contains a measuring probe which includes a light transmitter and a light receiver. The light receiver receives the light emitted by the light transmitter and reflected by the blood. The light transmitter and the light receiver are connected in parallel to an evaluation circuit via two common lines, this evaluation circuit charging the measuring probe with a constant current or with a constant voltage. A resistor is arranged in series with the light receiver. A transistor is arranged parallel to this series circuit, the base thereof being connected to the junction of the resistor and the light receiver. By means of this arrangement, the measurement sensitivity given deposits on the probe is maintained at a higher level. In an alternative embodiment, this can also be achieved using a resistor in series with the light transmitter with a transistor controlled by the light receiver connected in parallel therewith.

摘要： A sensor arrangement for controlling an implantable device, such as a heart pacemaker, has a number of individual sensors connected to an evaluation circuit through a catheter having at least two leads. The sensors are respectively activated in chronological succession by a shared control circuit, with both the sensors and the control circuit being arranged in the catheter. The corresponding measured signals are transmitted via the same leads, and also being offset chronologically. The arrangement permits a number of sensors to be connected to a catheter while maintaining only two lines in the catheter, so that the flexibility and reliability of the catheter, which are best with the fewest possible leads, remain unimpaired.

摘要： In order to be able to automatically locate and map ammunition over a large area without endangering the searching crew, ground-scanning sensors are mounted on a relatively light-weight, unmanned, remote-controlled vehicle which then travels over the area contaminated with ammunition. The controlled vehicle is controlled from, and the sensor signals are evaluated in, a second vehicle which is generally disposed in the immediate vicinity of the area being examined. The controlling vehicle, which is preferably armored, also accommodates the operating crew.
