  1. Eagle-Eye Golf Ball Finder James Valfre Paul Brunner Krystal Lucas Anne Grigals

  2. Problem Situation • Missing golf balls require expending energy and time to find • Lost golf balls cause a monetary expense to the player for replacement • Lost golf balls result in penalty strokes and frustration with the game • Golfers searching for missing golf balls cause a slow-down in play and less course throughput Eagle-Eye Golf Ball Finder

  3. Requirement Creation • Budget • Schedule • Technology availability • Interface • Standards • Consistency across terrains • Reproducibility • Time Required to find Ball • Physical Damage to Ball • System Availability • Reliability • Safety • Justifiable Customer Cost/Maintenance • Short Training Time Eagle-Eye Golf Ball Finder

  4. Schedule Requirements Creation 8/2 Document 6 9/10 Document 2 9/24 Document 3 10/1 Document 5 10/15 All Documents 12/10 Eagle-Eye Golf Ball Finder

  5. Concept Exploration • (1) Sound-emitting ball • (2) Brightly colored ball • (3) Dog Chaser • (4) Golf Lessons • (5) Fixed Sensors on Course • (6) GPS ball • (7) RF ball • (8) Do Nothing Eagle-Eye Golf Ball Finder

  6. Concept Evaluation(using Sum Combining Functions) Final Score .70 .68 .71 .74 .65 .60 .81 .73 Concept 1: Sound Emitting Concept 2: Brightly colored Concept 3: Dog Chaser Concept 4: Golf Lessons Concept 5: Sensors Concept 6: GPS Concept 7: RF Tag Concept 8: Do Nothing Eagle-Eye Golf Ball Finder

  10. Sensitivity Analysis 64/36 Resource Performance Eagle-Eye Golf Ball Finder

  11. RF System • Built-in, spherical, semi-active RF tag • Handheld locator device • Handheld transmits a set RF frequency and receives a return signal from golf ball • Handheld indicates correct direction Eagle-Eye Golf Ball Finder

  12. Eagle-Eye RF System Ball lost in rough. Handheld transmits at set frequency. Ball absorbs power from magnetic field and transmits back to hand- held. Player knows direction to walk. 2.4 GHz RF Signals at set frequency

  13. RF Schematic Diagram of signal and data flow. Shows how battery is recharged. Battery in Tag power-boosts the return signal to allow system to function over an approximate range of 100 meters.

  14. 1.68” 0.75” 0.75” RF Ball Prototype Research Indicates Coin-Size RF tags with integrated thin-film rechargeable battery are feasible.

  15. Requirements Validation & Verification Requirement Consistency Across Terrains Operator Reproducibility Time to Locate Ball Physical Damage to Ball Availability Reliability Method D T T T/I A A Method Legend: D = Demonstration T = Test I = Inspection A = Analysis Eagle-Eye Golf Ball Finder

  16. Requirements Validation & Verification Requirement Safety Conformity to USGA Cost of Design/System System Design Time Operating and Maintenance Selling Price Training Time Method A T/D/I A A A A D Method Legend: D = Demonstration T = Test I = Inspection A = Analysis Eagle-Eye Golf Ball Finder

  17. Test Plan • Golfer will hit ball into three coverage areas: heavy trees, tall grass and sand • Five golfers hit a ball and record their search time • Pro golfer will try to hit a target. This is compared against his precision and accuracy with a standard ball. Eagle-Eye Golf Ball Finder

  18. System Implementation • Research yielded potential designs • Trade Study indicated appropriate concept • Tests developed to support concept decision • System could be ready to build summer 2004 Eagle-Eye Golf Ball Finder

  19. Lessons Learned • Team could work on a project successfully despite not being at same site • Customer requirements do drive the concept design decision Eagle-Eye Golf Ball Finder

  20. Conclusion • Team determined RF tag concept was the best alternative • Eagle-Eye Golf Ball Finder would meet customer’s needs Eagle-Eye Golf Ball Finder
