Abstract: Configurations of a stylus and controlling methods thereof are disclosed. The proposed stylus causes a touch panel to generate a signal by an electrical field generated by a magnetic field via one of a conductor and an electric plate, wherein the stylus includes a set of windings and a magnet, which can move towards each other and generate a current on the set of windings through interaction. The current flows through the conductor/electric plate on a tip of the stylus to generate one of an electric flux line and a magnetic flux line such that the touch panel can sense the movement of the stylus.

Abstract: A light-energy stylus with a light guide having a distal end disposed near a tip of a housing and exposed on a surface of the housing. Light enters the light guide from the distal end, travels through the light guide and is then collected at a proximal end of the light guide. A photovoltaic element converts the collected light into electrical energy. Accordingly, in addition to performing touch functions, the light-energy stylus may execute bi-directional data communication with a touch panel.

Abstract: A method for detecting errors in driving device of head light of vehicles utilizes a microprocessor control unit of a main circuit to detect the position of the driving shaft by checking the change of magnetic field or resistance of the driving member and the change of magnetic field or resistance is compared with a pre-set value to decide the position of the driving shaft. The motor is then commanded to drive the driving shaft to the pre-set position. The method detects the position of the head light before the drivers drive the vehicles on the road and if the head light is not in a desired position, the user can adjust the head light position to prevent potential risk on the road.
