Abstract
The present invention is a cant angle sensor assembly which senses the amount of tilt of an object in the longitudinal, transverse and oblique directions and which effectively exhibits a damper action in all directions by a single magnetic damper means.
Claims11
A cant angle sensor assembly comprising:
- non-magnetic, conductive cup-shaped member;
- pendulum means suspending said non-magnetic, conductive cup-shaped member in a manner to freely rock in all directions;
- at least two magnet means;
- magnetic damper means with a stationary side along one face side of said cup-shaped member, said magnetic damper means including said at least two magnet means arranged on said stationary side along one face side of said cup-shaped member through a gap, said at least two magnet means having polarities opposite to each other with respect to said cup-shaped member;
- and
- photo-sensor means for sensing the rocking state of said cup-shaped member in said all directions, said photo-sensor means includes an optically reflective pattern formed on the bottom of said cup-shaped member and a photo-sensor disposed at said stationary side of said magnetic damper means in a position to face said optically reflective pattern and to coact with said optically reflective pattern to sense the rocking state of said cup-shaped member in said all directions.

A cant angle sensor assembly comprising:
- non-magnetic, conductive cup-shaped member;
- pendulum means suspending said non-magnetic, conductive cup-shaped member in a manner to freely rock in all directions;
- a magnetic means;
- magnetic damper means for exerting a magnetic force upon said cup-shaped member, said magnetic damper means including said magnetic means arranged on a stationary side of said magnetic damper means along one face side of said cup-shaped member through a first gap;
- a magnetic force assisting member arranged on said stationary side of said magnetic damper means at the other face of said cup-shaped member through a second gap;
- and
- photo-sensor means for sensing the rocking state of said cup-shaped member in said all directions, said photosensor means includes an optically reflective pattern formed on the bottom of said cup-shaped member and a photosensor disposed at said stationary side of said magnetic damper means in a position to face said optically reflective pattern and to coact with said optically reflective pattern for sensing the rocking state of said cup-shaped member in said all directions.
