A rotary variable resistor includes a resistance circuit module, a fixation frame, a brush assembly and a rotor shaft. The resistance circuit module has a circuit board, an output circuit, three input circuits and a resistance ring. The output circuit includes a brush contact port having an annular brush contact area and an output port extending out from the brush contact port. Each input circuit has a resistor contact end and an input port. The three resistor contact ends are evenly annularly separated. The resistance ring co-axially and annularly spaced to the brush contact port contacts the resistor contact ends. The fixation frame is fixedly mounted on the resistance circuit module. The brush assembly rotatably restrained by the fixation frame bridges the annular brush contact area and the resistance ring. The rotor shaft for driving the brush assembly is connected with the brush assembly.

A rotary position sensor configured to transmit the rotational motion from the outside to a rotating body with high accuracy, allowing inspection without affecting the shaft hole includes a rotating body including a cylindrical shaft body having a shaft hole and a flange continuously connected to the shaft body and extending outward in a radial direction of the shaft body, a housing including a bearing through which the shaft body of the rotating body is inserted, and a measuring unit configured to measure a relative position of the rotating body to the housing, wherein the flange includes an engaging portion on a periphery thereof.

In a method of manufacturing a cartridge of an electronic vaping device, wherein the cartridge includes a pre-vapor formulation storage element, an electrical resistor is physically manipulated to change a resistance of the electrical resistor from a first resistance value to a second resistance value, the second resistance value indicative of a pre-vapor formulation substrate contained in the pre-vapor formulation storage element. The electrical resistor is then mounted to a portion of the cartridge.

An impedance synthesis method for single and multi-probe high resolution slide screw impedance RF and microwave tuners employs a fast calibration algorithm, which creates appropriately distributed calibration points over the Smith chart and a second order interpolation algorithm between calibration points, optimized for best suitability to the natural behavior of the tuners. The fast tuning algorithm uses a general search in order to identify the closest calibrated points, followed by a gradient search using fine interpolation grid in order to reach the final target. The method is applicable, after proper data preparation, also to double and triple probe harmonic tuners. The method allows tuning accuracy as high as 60 dB, or deviation-from-target vector distance of 0.001 units on the Smith chart, whereas absence of the fine grid interpolation typically yields accuracies of the order of 20 dB, or a deviation-from-target vector distance of 0.1 reflection factor units.
