Method and system for measuring the variation in speed of a moving body
First Claim
1. A device for measuring an acceleration of a moving body, the device comprising:
- a solid body having a moving part and an internal cavity capable of allowing for a free movement of said moving part, said solid body having two lateral parts and a central part, said central part having an opening formed therein that forms at least one part of said internal cavity, said central part being sandwiched between said two lateral parts;
said internal cavity having at least one wall capable of forming a sloping track, said sloping track having a surface allowing for the free movement of said moving part on said sloping track in said internal cavity between an initial position at rest and a distant position spaced from the initial position situated at an end of said internal cavity and reachable by said moving part during a variation in acceleration;
said moving part capable of moving from the initial position to the distant position in said internal cavity under an effect of the acceleration of the moving body; and
at least one detector capable of detecting a presence of said moving part at the distant position.

Abstract
A device and method measure an acceleration of a moving body. The device contains a solid body having a moving part and an internal cavity capable of allowing for a free movement of the moving part. The internal cavity has at least one wall forming a sloping track, the sloping track having a surface allowing for the free movement of the moving part on the sloping track between an initial position at rest and a distant position spaced from the initial position situated at an end of the internal cavity and reachable by the moving part during a variation in acceleration. The moving part moving from the initial position to the distant position in the internal cavity under an effect of the acceleration of the moving body. At least one detector is provide and is capable of detecting a presence of the moving part at the distant position.

13. A method for measuring an acceleration of a moving body, which comprises the steps of:
-
during an acceleration of the moving body, a movement occurs, in a closed cavity, of a moving part from an initial position at rest to a distant position, the moving part being capable of moving freely from the initial position at rest to the distant position from the initial position, the initial and distant positions being linked by a sloping, continuous track formed by a wall of the closed cavity and capable of allowing for the movement of the moving part between the initial position and the distant position on the sloping, continuous track, a solid body including the closed cavity having two lateral parts and a central part sandwiched between the two lateral parts, the central part having an opening formed therein that forms at least one part of the closed cavity; and detecting, via a detector, a presence of the moving part at the distant position. - View Dependent Claims (14)
