Detecting movement characteristics of an object
First Claim
Patent Images
1. A method of determining a movement characteristic of an object, comprising the steps of:
- a) reflecting electro-magnetic energy off the object;
b) receiving the electro-magenetic energy reflected off the object at a sensor; and
c) determining a movement characteristic of the object based on the reflected electro-magnetic energy.

Abstract
System and method that measures and displays information about the conditions of a moving object, in particular a sports object such as a golf ball. In particular, the device measures the speed and direction of movement, as well as spin rate and spin axis orientation of the object by analyzing the data generated by one or more continuous wave radar sensors.
