    Abstract: A method is disclosed for calibrating a trigger unit which is connected via a trigger line to at least two sensors configured to be triggered. Each sensor is connected between two successive line portions of the trigger line. Each sensor has an input and an output, a controllable interrupter between the input and output; and a control circuit, which controls the interrupter. The interrupters of all sensors are initially open. The method comprises the following: transmitting a trigger pulse; in the sensor: receiving the trigger pulse and returning a response; in the trigger unit: receiving the response and calibrating the trigger unit; repeating the aforementioned steps, wherein each sensor reflects the trigger pulse, and the trigger unit measures the propagation times and is calibrated thereto.

    Abstract: A circuit assembly for plausibility checking of sensor signals, which can be generated by at least two separate sensor elements, includes at least one evaluation and control unit which receives the sensor signals via at least one interface unit and evaluates the received sensor signals for generating sensor data. A first evaluation and control unit is configured to receive the sensor signals of a first sensor element and to generate first sensor data from the first sensor signals. The first evaluation and control unit is configured to provide the generated first sensor data via at least one interface unit to a second evaluation and control unit, which receives and evaluates the sensor signals of a second sensor element to generate second sensor data. The second evaluation and control unit compares the generated second sensor data and the generated first sensor data to each other and inspects them for plausibility.

  • Patent number: 8868236
    Abstract: A method and apparatus for calibration of a robot on a platform and a robot, in relation to an object using a measuring unit mounted on the robot including placing CAD models so that the robot reaches the object, manipulating the CAD models to move the measuring unit to a pose in relation to the platform allowing measurement of a feature on the object, storing the pose, and generating a CAD model of the feature. The real robot is moved to the pose, the real platform is moved where measurements of the feature can be made, 3D measurements of the feature are performed and based thereon generating a second CAD model, performing a best fit between the CAD models, and calculating a 6 degrees of freedom pose difference between the CAD models, and instructing the mobile platform to move to compensate for the pose difference.

The system also includes a passive signal modification circuit. The passive modification circuit is configured to receive the signal and generate a modified signal based on the received signal. Additionally, the modified signal that is generated has a characteristic that it exceeds a threshold value for an amount of time greater than a second amount of time that the received signal exceeds the threshold value. The passive modification circuit is further configured to control the amount of time that the modified signal exceeds the threshold value.

  • Patent number: 8823400
    Abstract: A diagnostic method and system is described for diagnosing an operating condition of a conductive particulate matter sensor. The sensor has a substrate with electrical resistance that varies with temperature and two electrodes on the substrate adapted to collect particulate matter between the electrodes, thereby establishing an electrically conductive path through collected particulate matter between the electrodes that can be detected by measuring electrical resistance between the electrodes, Relect. The diagnosis is performed by heating the substrate in the area between the electrodes and using the resistance between the electrodes to determine detecting whether contamination is present on the surface of the sensor. Heat may be maintained on the sensor to attempt to burn off a detected contaminant, and a subsequent resistance reading may be used to determine if the contaminant was successfully burned off.

  • Patent number: 8794046
    Abstract: Self-diagnosis of a particle sensor may be used for determining a particle content in a gaseous stream. The particle sensor may include at least two interlocking, interdigital electrodes and a heating element. The heating element may be separated from the electrodes by an insulation layer. The particle sensor may be heated in a regeneration phase and a soot load on the particle sensor can thereby be removed. A semiconductive layer may be formed in the insulation layer directly beneath the electrodes by means of external doping or auto-doping. To perform a self-diagnosis, a measurement voltage may be applied at least periodically between the electrodes and a self-diagnostic current may be measured.
