Abstract: A compensation method for an induced amount in a touch sensor and a touch panel thereof are provided. The compensation method uses a fake finger circuit to simulate the situations when a user touches the sensing nodes of the touch sensor with a finger, and obtains the gain coefficient of each of the sensing nodes, which are used to compensate for the induced capacitance generated by the sensing nodes as a result of being touched by an external object. In this way, the extra effects caused by the difference in basic capacitance can be eliminated by the gain coefficient.

Abstract: A method for tracking and positioning a magnetic catheter and a structure of a magnetic catheter are disclosed for facilitating tracking and positioning of catheters in human bodies without using electromagnetic induction as conventionally used. When electromagnetic induction and remote magnetic control are used together, their respective magnetic fields may mutually interfer, increasing the risk of operational errors of the magnetic catheters they are working on. The disclosed magnetic catheter has an elastic unit. While the magnetic catheter bends, inductance variation caused by elastic deformation of the elastic unit is measured for calculating an actual bending angle of the magnetic catheter. Then the motion of the magnetic catheter can be amended accordingly. By using calculation instead of electromagnetic tracking, mutual interference between different magnetic fields can be prevented.
