US 2006/0145707 A1 · Device for generating electrical signal corresponding to change in position or posture

Abstract

[Problem] To provide a compact device for generating an electrical signal corresponding to a change in position or posture, which can be used in such as posture control of a ship, a motor vehicle, aircraft, or the like, and detection of action or posture of various parts of a human body. [Means for Resolution] A device for generating an electrical signal corresponding to a change in posture includes: a container which is formed of an electrical insulating material and is fixed to an electrode holder formed of an electrical insulating material and in which a fluid dielectric is sealed with a volume ratio sufficient to have an angle of inclination with respect to a free surface of the fluid dielectric; a plurality of pairs of peripheral electrodes disposed at positions which are symmetrical about a central point of a cross section of the container at a predetermined interval with an inner peripheral surface of the container; and a pair of counter electrodes which are electrically insulated from each other and are respectively disposed at an upper surface of the electrode holder which serves as a bottom of the container and at a lower surface of a ceiling of the container at the central point of the cross section of the container, a voltage being applied to the pair of counter electrodes.

A device for generating an electrical signal corresponding to a change in posture comprising:

a container (2) which is formed of an electrical insulating material and is tightly fixed to an electrode holder (1) formed of an electrical insulating material and in which a fluid dielectric (B) is sealed with a volume ratio sufficient to have an angle of inclination with respect to a free surface of the fluid dielectric;
a plurality of pairs of peripheral electrodes (4) disposed at positions in such a way that each of said plurality of pairs of peripheral electrodes are symmetrical arranged perpendicular to the electrode holder in respect of a central point of a cross section of the container so as to be apart from an inner peripheral surface of the container with a predetermined interval therefrom;
and
a pair of counter electrodes (3), being electrically insulated from each other, which are opposed each other along an imaginary line perpendicular from a central point of the cross section of the container, each of said pair of counter electrodes being perpendicular to an upper surface of the electrode holder, serving as a bottom of the container, or perpendicular to a lower surface of a ceiling part of the container, characterized in that an external voltage is applied to the pair of counter electrodes so that an electrical signal corresponding to a change in posture can be generated.
