Circular or pointed body e.g. skittle ball`s, linear path parameter determining method, involves detecting presence of body within sensor ranges, and determining parameter from point of time to which body arrives in and out of ranges

摘要

The method involves arranging three sensors, which are spaced from one another, in a plane. The sensors detect the presence of a circular or pointed body e.g. pendulum, within sensor ranges. Parameter of path is determined from point of time to which the body arrives in and out the sensor ranges of the individual sensor. The parameter of the path is determined by an approximation method.
