    • A device to carry out a bioelectrical interaction with an individual by means of electrodes 29, 29a whereby an on-demand verification of the integrity of the electrical contact of the electrodes is implemented. The device 20 comprises a control unit 22 arranged to determine an occurrence of the predefined event related to a quality of a measured signal. In case the predetermined event is detected, the control unit 22 actuates the testing means 24. The testing means is arranged to generate the test signals, I1, 12 and to apply them via a coupling circuit 23, 23a to the electrodes. In case it is desired that cumulative information about the contact integrity is obtained, is it sufficient to apply a single test signal per electrode. In case it is required to determine which of the electrodes has lost its contact, a sequence of test signals is generated by the sequencer 24b. The response signal from the electrodes 29, 29a is forwarded to the input filter 26, which is preferably also used for a normal signal analysis. The signal from the input filter 26 is directed via the input impedance 25, 25a to the input amplifier 28. The amplified response signal is forwarded to the signal processing means 30 which is arranged to analyze the response signal. Preferably, an amplitude analysis is done. The signal from the signal processing means 30 is supplied to the analog-to-digital converter (ADC) 32 after which a digital processing of the response signal is carried out by means of a further processing unit 34. In case the further processing unit 34 determines that the integrity of the contact is below the allowable level, the lead-off indicator 36 is actuated.

    • The invention concerns a procedure to ascertain a concentration of sooty particles in an exhaust gas system of an internal combustion engine or a depletion of an emission control system of the internal combustion engine due to the loading of sooty particles, whereby the sooty particle concentration in the exhaust gas system is determined by means of a collecting particle sensor, which emits a sensor signal and whereby the depletion of the emission control system due to the loading of sooty particles is determined from the sooty particle concentration.The task is thereby solved, in that the sensor signal is corrected by means of predetermined corrections with regard to a sensor temperature and/or an exhaust gas temperature and/or a flow velocity of the exhaust gas and/or a voltage applied at the particle sensor. Transverse sensibilities of the particle sensor can thereby be taken into account during the evaluation; and the determination of the accumulated loading of sooty particles and the determination of the sooty particle concentration in the exhaust gas system are improved. In the process, the sensor temperature enters into the correction to the extent that a temperature dependence of the electrical resistance of the loading of sooty particles is determined in a preparation phase and can be taken into account during the evaluation of the sensor signal.
    • 本发明涉及一种确定内燃机的排气系统中的煤烟颗粒的浓度或由于烟灰颗粒的装载引起的内燃机的排放控制系统的耗尽的过程,由此烟灰颗粒浓度在 排气系统通过采集颗粒传感器确定,该传感器发射传感器信号,并且由烟尘颗粒浓度确定由于烟灰颗粒的装载引起的排放控制系统的耗尽。 因此解决了这个任务,因为传感器信号通过关于传感器温度和/或废气温度和/或排气流速和/或施加在颗粒处的电压的预定校正来校正 传感器。 因此可以在评估过程中考虑粒子传感器的横向敏感性; 并且改善了排烟系统中煤烟颗粒的积累负荷的确定和烟尘颗粒浓度的测定。 在该过程中,传感器温度进入校正,使得在准备阶段确定了烟尘颗粒的负载的电阻的温度依赖性,并且在传感器信号的评估期间可以被考虑。
