Abstract
The present invention discloses a tilt sensor including a container having a bubble on a surface of the conductive liquid as the conductive liquid is filled in the container, an electrode to provide a current to the conductive liquid in the container, and terminals to output the current provided from the electrode through the conductive liquid, thereby outputting a tilt sensing signal by the presence of an electric connection between the electrode and the terminals.
Claims18
A tilt sensor, comprising:
- a container of a predetermined dimension;
- a conductive liquid provided in said container, said conductive liquid including a nonconductive bubble on the surface thereof;
- an electrode mounted on an inner surface of and projecting to an interior of said container for providing an electric potential to said conductive liquid in said container;
- a plurality of terminals mounted on the inner surface of said container and having respective exposed portions spaced from said electrode, each of said plurality of terminals whose exposed portion contacts said conductive liquid outputting a current due to the electric potential provided from said electrode to said conductive liquid, thereby outputting a tilt sensing signal;
- and
- an insulating material coating each of said plurality of terminals except the respective exposed portions such that only the exposed portions may contact said conductive liquid.
