  2. Ping Project Objectives • Complete analysis of putter stroke • Velocity • Force • Trajectory • 3-D motion • Impact location • Club angles • Stand Alone Unit • Clips onto putter

  3. Ping Inc. Specifications • Angle Measurements: • Driver max angle = 540 • Putter max angle = 100 • + 0.5 - required • + 0.1 - desired • Speed Measurements: • Driver Max Velocity = 150 mph • Putter Max Velocity = 20 mph        • + 0.5 mph - required • + 0.1 mph - desired • Swing Weight Center of Balance: • 14” from top of shaft • Communication: • Wireless: 80.211B • Club Weight: • Putter Head Weight = 350 grams • Driver Head Weight = 250 grams • Device Weight: • < 10% of head weight

  4. Marketability • Ping Inc. • Will use this technology to customize clubs to meet individual needs • Compensation for swings • Weight • Clip On • Easy to use, can be used with any club • Natural enviroment provides best results • Less than $3000 makes it affordable to the avid golfer

  5. Current Progress • Determined photo sensors for impact location • IR Reflection Sensors • Obtained 3-D positioning system 3DM-G • Combonation of Accelerometers and Gyroscopes positions in 3-D • Initial prototype testing • Voltage Curves for IR • Positioning of 3DM-G

  6. Initial Design

  7. Communication System We plan on designing and implementing a wireless communication system to replace the cable link between the 3DM-G and the computer.

  8. Data-Flow Diagram 3DM-G Buffer Transmitter Computer Receiver

  9. 3DM-G • Contains: • Accelerometers (3) • Gyroscopes (3) • Processor • Power • 5.2Vdc min • 12Vdc max • 52mA current • Outputs: • RS-232 interface • 100Hz data rate • Acceleration vectors • Angles

  10. Buffer • Flash Memory • Used to store the data from the 3DM-G so that the data can be sent at a slower rate across the transmission channel. • Processor • Interface Control between 3DM-G, Buffer, and Transmitter

  11. Transmission Link • RF Transmitter/Receiver • Prefabricated Unit • Serial Port compatible • Frequency and Data Rates • Typically small for small units • Data must be stored and sent out at this slower rate

  12. Power Requirements • Small Power • Portable clip on system must be light • Small batteries should be used • Parts used should be light, low power units • Longevity • Must last a round of golf • On/Off switch to conserve power • Possible stand-by modes

  13. Projected Problems • Size and Weight constraints • Hard to design to not interfere with putter weight and feel • Data Rates • Synchronization between components • Education • Digital Signal Processing is a weakness for our group • Communications between departments • ME/Ping may change design specifications • Specifically, 3DM-G box may not be used in final project

  14. Contingencies • Data Rate • Once designed, changing the input (3DM-G) should have little consequence to overall outputs • Size and Weight • Prototype needs to be a proof of concept, and most components can be manufactured more compact • DSP • Use more knowledgeable resources

  15. Schedule

  16. Estimated Costs • Development Costs (per unit) • Parts: $2k • Labor: Students pay to work: ($8k) • Retail Costs • Parts: $1.5k • Manufacturing and Marketing: $500 • Suggested Retail Price Per Unit: $3.5k
