Abstract

A system for determining the relative displacement of a rigid object is described herein. In one embodiment, the system includes three data sources positioned on an object. The data sources are configured to transmit data relating to positional displacement of the object. Each data source has predefined movement parameters based on the position of each data source on the object. In one embodiment, the system further includes a receiver unit configured to display positional information relating to the object based on the data received from each data source. The positional information represents a single valid solution set generated in part by eliminating positional movements that exceed the predefined movement parameters.

Claims

1. An apparatus for determining the relative displacement of a golf putter, comprising:

a transmitter unit; and

a receiver unit;

wherein the transmitter unit is removably attached to a putter shaft, the transmitter unit includes a first, a second, and a third light emitting diode for transmitting positional data relating to the putter to the receiver, the first diode is positioned above the second diode such that a line defined by the center of the first and the second diodes is vertical to each other, the third diode is positioned along an arm extending outward from the putter shaft and backward in a direction generally away from the direction of data transmission so as to be farther from the receiver than the first and second light emitting diodes, the diodes having predefined movement parameters based on the position of each diode on the golf putter; and

wherein the receiver unit includes;

an optical receptor to collect the data from each diode; and

a processor for processing the data to provide a single valid solution set generated in part by eliminating positional movements that exceed the predefined movement parameters

a display for viewing the valid solution set for the purpose of at least stroke analysis.

2. The apparatus of claim 1, further comprising:

three data sources positioned on an object, the data sources configured to transmit data relating to positional displacement of the object, each data sources having predefined movement parameters based on the position of each data source on the object; and

a receiver unit for receiving the data relating to positional displacement from each data source, and

a processing means for processing the data to provide positional information representing a single valid solution set generated in part by eliminating positional movements that exceed the predefined movement parameters.

3. The apparatus of claim 2, wherein the receiver unit is configured to display positional information relating to the object.

4. A method for determining the relative displacement of a golf putter, comprising the steps;

providing the apparatus of claim 1;

providing three data sources to transmit data relating to the positional displacement of an object;

providing a receiver to receive the data transmitted by the data sources;

positioning the data sources on the object;

predefining movement parameters of the data sources based on the positioning of the data sources on the object;

transmitting the data from the data sources;

receiving the data from the data sources be the receivers;

eliminating data that exceeds the predefined movement parameters so that a single valid solution set representing the positional displacement of the object remains; and

displaying information relating to the remaining positional displacement data.
