Measurement of object acceleration using a black sphere mounted in the center of a cube by three pairs of springs with integral light emitter and photocell pairs so that changes in cell resistance can be linked to acceleration

摘要

Sensor comprises a cube with a black sphere mounted in its center using three pairs of springs along each of three coordinate axes. Light emitter-photocell pairs are also integrated in the cube along each of the coordinate axes. If the sphere accelerates the resistance of the photocells changes and can be measured. The cube is attached to the surface of the object whose acceleration is to be measured.
