First Claim
1. A system for making measurements on moving objects said system comprising:
- a) a first sensor that can detect a movement of objects,b) a second sensor that can detect the movement of objects,c) a processor that acquires data from the sensors, calculates measurements related to the movement of the objects and reports the measurementsd) where the processor filters the raw data used in its calculation, said filters based upon both intrinsic information and data acquired by both of the sensors,e) where intrinsic information is at least one selected from;
i) a maximum speed for the objects,ii) a minimum speed for the objects,iii) the three dimensional location of the objects at a start of the movement,iv) the three dimensional location of the objects at an end of the movement, and,v) a time interval between the start of the movement and the end of the movement,f) where the measurements are at least one selected from;
i) the average speed of the objects,ii) the maximum speed of the objects,iii) acceleration of the objects, and,iv) a video of the objects during their movement.

Abstract
A sensor system and method of using the system synergistically to improve the accuracy and usefulness of measured results is described. The system is comprised of electronically linked components that act as markers to trigger events, producers that gather data from sensors and aggregators that combine the data from a plurality of producers using triggers from marker devices to select the data of interest. The system is shown to be applicable to selection of data regions of interest and to analysis of the data to improve accuracy. The analysis of the data of any particular sensor within the system makes use of extrinsic data, being data generated by other sensors and intrinsic data, that is data or data limits that are known to be true from nature, laws of physics or just the particular information the user wants to acquire. The system is demonstrated on the analysis of Doppler radar measurements of a thrown object.

8. A method for analysis of Doppler radar data said method including:
-
a) acquiring pulse data from a Doppler radar sensor, said pulse data indicative of a speed of an object within the field of view of the Doppler radar sensor b) preparing a histogram of the pulse data, said histogram comprising parsing the data into time buckets based upon the pulse width of individual pulse data points and the frequency of occurrence of data points within the time intervals, c) filtering the data to remove pulse data that is less than a preselected minimum speed, d) filtering the data to remove pulse data that indicates a speed greater than a preselected maximum speed, e) filtering the data to remove pulse data that occurs outside of a time interval said time interval defined by a second sensor, f) filtering the data to remove pulse data that indicates an acceleration outside of a preselected acceleration range, g) selecting a bucket from the histogram with the highest frequency of occurrence of pulse data, h) calculating a weighted average of the pulse data including the bucket with the highest frequency of occurrence of pulse data and a preselected number of neighboring buckets, i) reporting the speed of the object based upon the weighted average pulse width. - View Dependent Claims (9, 10, 11)

12. A communication system and protocol for acquiring data related to a sport activity comprising:
-
a) a marker device that includes an electronic sensor that detects an external event related to the sport activity said marker device sending a trigger signal when the sensor detects an external event, b) a producer device that includes an electronic sensor that detects an external event related to the sport activity and said producer device records in an electronic memory a signal from the electronic sensor in the producer device and transmits the recorded signal, c) an aggregator device that receives the trigger signal from the marker device and receives the transmitted recorded signal from the producer device and filters the transmitted recorded signal to include only data that corresponds to data recorded in a pre-selected time interval around the time of the trigger signal and displays the filtered data on an electronic display included in the aggregator device. - View Dependent Claims (13, 14, 15)
