Abstract: This application relates to a resistance measurement method and apparatus for an atomizer, an electronic atomization device, and a storage medium. The method includes: reading a resistance value of the atomizer at intervals of first preset time and obtaining a first preset number of first resistance values; starting the atomizer and continuing for second preset time; reading the resistance value of the atomizer at intervals of third preset time and obtaining a second preset number of second resistance values; and calculating an average value of the first resistance values and the second resistance values as an initial resistance value of the atomizer. Through this method, the accuracy of the initial resistance value measurement of the atomizer can be improved.

Abstract: A mold for synthetic resin products which are to be shaped while soft, includes a pair of elongated mold parts each having opposed complementary faces with contours at least partially conforming to at least parts of the product to be shaped. A support means on which the mold parts are mounted provide for moving at least one of the mold parts relative to the other mold part to effect removal therefrom of a finished product. The mold parts are constructed and arranged so as to be bendable along their longitudinal axes to effect a change in arcuate configuration, the mold parts being made of a material which facilitates sliding of the synthetic resin product through the mold, the support means supporting the mold parts in fixed spaced apart disposition as the product is moved longitudinally between the mold parts to thereby impart to the product an arcuate configuration corresponding to the arcuate configuration of the mold parts.

Abstract: A linear motor comprises an armature (14,15,16) and a stator (11,12) each adapted to provide a sequence of North and South poles along the length of the motor. The pole pitch of the stator magnets is different from that of the armature coils (15,16) such that with appropriate energisation of the coils this difference in pole pitch and stator can result in a net thrust of the armature relative to the stator in a desired direction at any location within a range of relative longitudinal positions of the armature and stator. The motor may be subject to closed loop velocity - and/or positional control and means are disclosed to achieve this. Several variations in pole configurations and means of controlling the coil energisation are disclosed.
