    1480193 Measuring moisture SAINTGOBAIN INDUSTRIES 16 April 1975 [19 April 1974] 15688/75 Heading G1N [Also in Divisions H2 and H5] A window pane 1 for a motor vehicle is provided on its internal face with a network 2 of electrically resistive strips printed on to the pane, and with a humidity detector Ha having two terminals one of which is connected to the network. Preferably the detector has a pair of inter-digitated electrodes of which one connects to a tab 2a formed on the uppermost resistance strip of the network. The detector forms with a resistance 23 a voltage divider for the signal generated by a multivibrator 11. The presence of moisture on the pane reduces the voltage supplied to the diode 15 whereby transistor 17 is blocked. Thus transistor 18 is enabled to act via the relay S to supply current to the network for heating the pane. In an alternative embodiment Fig. 2 (not shown) two humidity detectors are provided (Ha, Hb) coupled to the control circuit through respective capacitors (21a, b). The heater element may be energized in response to a bi-metallic strip (T) when the passenger compartment temperature is so low that there is a risk either of frost on the detector or of ice on the external face of the pane.

    FIG. 1 shows the functional scheme of the device with one or two parallel sensors located in the middle of the glass; in fig. 2 Also with two sensors, located on both sides of the heated glass.
    On the inner part of glass 1 there are placed heating elements made in the form of conductive tapes 2.1-2.5 (Parallel and connected to tires 3.1 and 3.2 pita, which is located on both sides of the glass 1, the humidity sensors consist of two pins 4.1-4.4 and 5.1-5.4, respectively, in the form of cable combs, one of which is connected either to the upper tape 2.1, or to the bus ZL,
    The system is printed on glass by
    silk screening method and welded before applying, contact 5.1 and two oCal contacts, namely the supply contact 6 of the bus 3.1 connected to the negative pole of the power supply av avtomobil, 8 as a battery 7 and contact 8 of the tire 3.2, connected to the switch 9 through output contact 10, controlled by winding 11, contact 11.1, and input contact 12 of the control unit. The heating elements are supplied with a constant voltage of 12 V, the control unit consists of a pulse generator assembled according to one multivibrator: a torus on two transistors 13 and 14, forewarning a power amplifier on a transistor 15, a detector assembled on a diode 16 and a capacitor 17, a dc amplifier on a transistor 18, a power amplifier on a transistor 19 in the power supply circuit of the winding 11 of the relay. A multivibrator operating with a frequency from 0/1 to 2 kHz and a preamplifier are interconnected by two capacitors 20 n 21 connected at the output of a resistor 22, Contact 5.1 of the humidity sensor is connected to the input terminal 23 of the control unit and connected to the capacitor connection point 20 and 21, due to which the sensor is passed to the input from the constant components of the signal at the output of the multivibrator and the input of the preamplifier. This sensor together with the resistor 22 forms a voltage divider for the alternating signal: Multivibrator ode. The voltage accumulated by the capacitor 21 on the base of the transistor 15, and: 1 month in the direction opposite to the specific conductivity of the casket.
    The drawings also show resistors 24.1-24.3, ensuring the operation of the pulse generator, resistors 25-31 and capacitors 32 and 33, ensuring the operating modes of the remaining device nodes, Fuse 34i is on the power supply circuit of the heating elements

    Sensors can be connected to the control unit and through capacitors 35 and 36 using input terminals 37 and 38 (FIG. 2). In this case, each of the sensors is connected to the output of the pulse generator through a capacitance formed by one capacitor, for example, 35, and the input of the preamplifier is through a capacitor formed by capacitors 35 and 21. The device has an additional thermal element 39, for example, a bimetallic plate grounded through the capacitor 40, shorting the humidity sensors when the temperature in the cabin is SHKOM low
    The device operates as follows, pa 3 ohm,
    When not covered by steam, and therefore has an increased impedance of about 1 MΩ, the variable component of the signal from the output of the multivibrator is amplified by the pre-amplifier, detected by the detector and opens the transistor 18, Under these conditions, the transistor 19 is blocked, and the winding 11 of the relay not fired, and glass heating does not occur.
    If the sensor is covered with parsm, then
    .. the resistance decreases to about 100 kOhl and the perpendicular component, rectified diode cm 16, is not sufficient to unlock the transistor 18. Under these conditions, the transistor 19 becomes conductive and causes the contact 11.1 to close, and this causes the heating glass It is also possible to introduce a feedback circuit between transistors 18 and 19 to compensate for the effects of fluctuations, in order to cause an oscillation to occur at a time when the voltage in the heating network changes. The humidity sensor has a base that is stretched or has a contact plate that allows the connection to be galvanized. The upper part of the sensor has a groove and is located at a sufficient distance from the edge so that the steam cannot
    It should be grounded, T1ri case can be added, the second sensor with contacts 4.2-5.2 (Fig, 1), Both sensors are located vertically on the symmetrical axis of the glass, динin - above the upper tape 2.1, the other - above the lower flax 2.5, The combined use of two sensors makes it possible to eliminate the effect of random disturbances emanating from the airflows that occur in an automobile. These air flows
    0 contributes, like electric heating, to the removal of steam, but usually they do not act equally on all glass, since the intensity, and often the area of action, depends on
    5 many factors, such as type
    autosmobile, window opening and ventilation openings, speed, number of passengers and T.fli Therefore, it is clear to connect contact 5.2 and contact 23, and you can also disconnect both sensors to avoid a possible asymmetric network (Fig. 2).
    A similar circuit is obtained by electroplating silver with silver by electroforming. Equivalent elements in this chain have the same numbers. The sensors are located on both sides of the glass, with contacts 4.3 and 4.4 of the sensors, respectively, connected to one of the tires 3.1 and 3.2 of the heating elements, and contacts 5.3 and 5.4 to two input contacts 37 and 38 of the control unit.
    Each of the sensors is separately developed by a capacitor, respectively, 35 and 36, and thus is separated from any constant component. The switching on of the pulse generator and the preamplifier occurs predominantly with psmsvda capacitor 21 at the output of the resistor 22. The operation of the device under the conditions that are foreseen in FIG. 2. Similar to the one described above, however, heating is caused by grounding the variable component through one or the other sensors, i.e. when there is steam on the glass, or through the bimetallic plate of element 39, when (the switch 9 is turned on by the driver of the car)
    The cabin cabin is still quite low in order for the sensor to be hoarfrost or to ice on the outside of the glass.
