Abstract
The invention provides an instrument responsive to acceleration forces. In the preferred embodiment, a body of magnetic material is positioned in a cavity such that it moves to a central position in response to a magnetic field and moves along a preselected path in response to acceleration forces. Means is included permitting the position of the body of magnetic material to be determined. The position of the body of magnetic material relative to the structure of the instrument is an indication of the acceleration force applied to the instrument.
Claims5
An instrument responsive to acceleration forces, comprising in combination:
- (a) a body of magnetic material;
- (b) spindle means adapted to support said body of magnetic material
- (c) a supporting structure having an outer perimeter and a cavity therein, said supporting structure also including channel means adapted to cooperate with said spindle means to support said body of magnetic material in said cavity such that said body of magnetic material is selectively movable along predetermined paths defined by said channel means;
- (d) magnetic means affixed to said supporting structure and adapted to produce a magnetic field in said cavity such that the position of said body magnetic material has a predetermined relationship to said magnetic field and the acceleration forces to which said instrument is subjected such that said body of magnetic material changes positions as said acceleration forces vary.
An instrument responsive to acceleration forces comprising in combination:
- (a) a supporting structure having an outer perimeter and a cavity therein;
- (b) first means for providing a magnetic field in said cavity, said first means including first and second permanent magnets positioned on opposed sides of said cavity;
- (c) a body of magnetic material;
- (d) a spindle having first and second ends and adapted to support said body of magnetic material;
- (e) second means for supporting said body of magnetic material within said cavity, said second means including first and second channels supported on opposite sides of said cavity, said channels being adapted to mate with said first and second ends of said spindle such that said body of magnetic material moves in a predetermined manner within said cavity in response to acceleration forces.
