    摘要: In order to separate, within a fluid (1), certain particles (2) contained therein, this fluid is arranged in a corridor (C) partly defined by two faces which are close together and substantially parallel to each other and to the direction of separation E and an exciting field is simultaneously applied to the entire volume of fluid contained in this corridor, according to a direction having at least one component perpendicular to the direction E, which exciting field varies along the said direction in a curve consisting of a regular sequence of mutually identical asymmetric patterns, the mean of this field, taken at each instant along the direction E, being zero, and means are provided for repetitively varying the effect of the exciting field on the particles. The substantially parallel faces may be electrodes between which a potential difference source is connected for producing an electric field thereby exciting particles in the corridor (C). At least one of the electrodes has a corrugated surface with a sequence of asymmetric grooves transverse to the separation direction.

When the sensitive foil is a polarized piezo-electric foil, the shims are directly interposed between one of the electrodes and the corresponding external protective foil..]. .Iadd.An apnea monitor/alarm consists of an electronic monitor circuit to actuate an alarm responsive to the output of a sheet-like electromechanical transducer. The transducer consists of an electret or polarized piezoelectric foil responsive to pressure to generate corresponding electrical signals, two film electrodes, and two protective foils. Shims are glued to two of the foils for spacing. If an electret sensor foil is used, the shims are directly interposed between the sensitive foil and one of the electrodes.

    摘要: A smoke detector includes a drift chamber and an ionization chamber formed by a first electrode and a second electrode. Electric charges are generated by ionization of the air. The drift chamber separated from the ionization chamber by the second electrode. The smoke particles penetrates from the environment to a detector inside the drift chamber. The electrical potential of first electrode exceeds a critical electric potential value for generating a corona discharge in the vicinity of the first electrode. The second electrode has openings for the electric charges generated in the ionization chamber to move to the drift chamber. The electric potential of the second electrode allows the electric charges in the drift chamber to move from the second electrode to the third electrode. The electric field between the second and third electrodes is at least 100 times weaker than the electric field between the first and second electrodes.
