    摘要： The device is able to detect the exceeding of a given threshold by a parameter, other than an electric voltage, capable of affecting the electrostatic force of attraction exerted between a charged electret and one, of two electrodes between which said electret is placed, said parameter being for instance an ionizing radiation. The two electrodes are at the same electric potential and the device also comprises return means for urging the first electrode and the electret permanently apart, and means for using the relative displacement of said elements, when it occurs, for desired detection purposes.

    摘要： The device detects variations in magnetic flux so that the passage through a given threshold by the amplitude of such a variation per unit time is manifested by the movement of an element adapted to trigger an action. It comprises a practically closed electrical circuit, such as a winding, arranged and mounted so that the variation in magnetic flux to be detected generates by induction at the terminals of this winding an electrical voltage V, two electrodes forming a capacitor, one of which is movable with respect to the other, an electret interposed between these two electrodes and whose charge produces a field exerting on these electrodes an electrostatic force H tending to bring them mutually together, means for forming a rectified voltage U from said voltage V and for applying this voltage U between the two electrodes in a direction such that the field which results therefrom is opposite that generated by the electret and hence tends to reduce the force H, and means urging the movable electrode scarcely reversibly in the opposite direction to the force H. The force G of these urging means and the charge of the electret are selected so that the overshoots by the voltage U of a predetermined threshold U.sub.o corresponding to the level to be detected of the magnetic flux-generating phenomenon cause swings of the movable electrode from its vigilance position to its active position, the triggering of said action being servocoupled to said swings.

    摘要： The invention relates to a device for measuring irradiation capable of modifying the charge of an electret. It is arranged in a portable cassette, between two electrodes held separated by a part and connected to a measuring circuit. A conductive shutter is movable parallel to itself and to the electret between this electret and than electrode, so as to alternately mask this electret with respect to this electrode and to render the electret visible to the electrode. The measurement exploits differences in charge of the electret read according to the movements of the shutter.

    摘要： A device for measuring quantities of electric charges, or other electric parameters whose magnitudes can be obtained from measurements of quantities of electric charges. The device includes a capacitor having a measuring plate and another plate or an intermediate element. The electrical parameter is applied to the capacitor so that a charge representative of its magnitude is induced on the measuring plate. This induced charge is modulated at a frequency f.sub.o and at a frequency f.sub.1, the frequency f.sub.1 being less than f.sub.o /2. An electrical signal representative of the modulation of the induced charge is generated. This signal has a first component of frequency f.sub.o whose magnitude represents the quantity of the induced charge and a second component of frequency f.sub.1 whose magnitude varies according to the distance between the measuring plate and the location at which the electrical parameter is applied to the capacitor. The second component can be used as a correction signal which reduces errors due to changes in the said distance.
