Abstract: A charging control circuit (23, 33, 43, 53), a charging apparatus (2) comprising the charging control circuit (23, 33, 43, 53), a charging control method and a charging method comprising steps in the charging control method. The charging control circuit (23, 33, 43, 53) and the charging control method can provide a variable current reference (Iref_g), and limit the variable current reference (Iref_g) to a minimum current value in a periodically triggered interrupt duration, so as to enable an output voltage (Vout) to be closer to a battery core voltage (V0) when the interrupt duration ends.

Abstract: Provided are a resistive touch panel detection method and apparatus. A resistance variance ratio of a Y plane relative to an X plane is calculated based on voltage detections before touching and after a two-point touch occurs; and then the inclination angle is calculated based on corresponding relationship between the inclination angle and the resistance variance ratio. To obtain a distance between the two points, the present invention the resistance variance ratio and a first ratio of a resistance variance of any one of the X plane and the Y plane relative to a total resistance of the any one plane are calculated; then a second ratio of an equivalent contact resistance at a midpoint relative to the total resistance is calculated; and the distance is calculated based on the resistance variance ratio, the first ratio, the second ratio, and a correlated relationship of the distance between the two points.
