  1. PROJECT P08005 ARC Communication Board

  2. Team Members • Cortney Ross (ME) – Project Manager • Kirk Marquard (ME) • Achilles Tziazas (CE) • Amy Koster (ID) • Rachel Lepkowski (ID) • Elizabeth DeBartolo (ME) – Project Guide • Daniel Phillips (EE) – Project Guide • Stan Rickel (ID) – Project Consultant

  3. Team Organizational Chart

  4. Project Overview • Our customer, Donna, is a mentally handicapped young adult who is in a motorized wheelchair. She has speech disabilities so she needs a special way to communicate with people who don’t know her well. She currently uses a book full of pictures that she and the staff that helps her is familiar with. Last year, a SD project designed a touch screen audio device to help her communicate with new people.

  5. Safety • Customer Safety • No Interference With Wheelchair Controls • Easily Be Able To Get Out of Way of Customer • Low Obstruction of Vision • Custom Enclosure • Product Safety • Fixed to Wheelchair • Adequate Product Size • Adequate Product Weight • Durable and Robust • Weather Resistant • User Friendly • Graphical User Interface • Picture Based • Flow of Components on Wheelchair (Overall System) • Customer Requests • Female Voice Output • Colorful and Girly Case • Convenience • Battery • Easily Charged • Able To Plug In and Recharge • Long Battery Life • System Must Be Fast • Customer • Left Hand Design • Antiglare Screen • Volume Adjustment for Staff • Upgradable By Staff Customer Needs

  6. Current Design: “Big Pink Box”

  7. Embedded Computer • Computer of choice: EBC-7040 • Reasons: • Cheap ($370) • Small size • Robust construction (absorbs vibrations, cushioned design, fanless operation) • ARM9 class processor (high performance & “ultra-low” power consumption) • Ready “out of the box” • Can come with both Windows CE or Debian Linux • Supports up to 1280x1024 resolution • Integrated Audio • Only weights 0.4kg • USB port for LCD Touch Screen

  8. Embedded Computer Issues: • Slow response time from Embedian.com affects buying all other components (Taiwan) • Embedian mentioned in their most recent e-mail that their Windows CE is “not mature yet” • There is still the option for Linux for this box though • Time is running out! • Backup plan: ARK-1370 by Advantech

  9. LCD Touch Screen LCD chosen: Caltron 12.1 inch Open Frame LCD (FBT-12120) • Reasons: • Choice of USB or Serial (chosen USB  Plug & Play) • Specs allow for 85% humidity • Thin design (only 1.45 inches thin) • Option of Resistive vs Acoustic Wave (chosen Resistive because of the ease of operation and it is also cheaper) • Satisfies desired resolution of 800x600 • Weight is O.K. : 1.4kg = 3.3lb • Price is around $600 before their educational discount • Has drivers for Windows CE and for “popular Linux distributions”

  10. LCD Touch Screen • Issues: • Caltron is out of these LCDs • New shipment coming in approximately 10 days without counting any other delays like issues at the customs  More delays • If we have to go back to using Linux, the drivers do not specify which Linux distributions are supported • Backup Plan: Use the LCD that is in the “big pink box”

  11. BatteryPower Requirements • Using: • h = 16 hours • EBC-7040: Needs a 12V, 32,000 mAh battery • LCD Touch Screen: Needs a 12V, 46,720 mAh battery • A 12V battery should provide the necessary currents. • Issues: • Should I add 32,000+46,720 to come up with the desired mAh? • Not an electrical engineer  Need more help with electrical engineering aspects of the project (already visited Dr. Slack)

  12. Operating System • Reasons: • Easier for the current developer to code using Visual Studio  Using previous knowledge • .NET is very popular and easy to program • Data from companies that develop embedded systems benefit Windows CE • Need less developers per project • Less “time-to-market” for Windows CE (number of months from design to first shipment) • Issues: • Issues with Embedian’s Windows CE

  13. Cable connector • Current decisions: • Looked into using a parallel cable to carry: • Audio (sound) • Video • Power • USB to the front panel • Results: • The only way to find out if it works is to actually implement this ASAP even without having the components (Dr. Slack’s suggestion) • Might face issues if a parallel cable is used, due to the reason that video is a high speed signal (Dr. Slack & Dr. Reddy) • It can be done but the only way to find out is to try it out

  17. Hand Sketched Case Designs

  18. Hand Sketched Case Designs

  19. Hand Sketched Case Designs

  20. SolidWorks Case and GUI Design

  21. Shock Mounting • What needs to be shock mounted? • Computer to wheel chair • Batteries to wheel chair • POSSIBLY LCD touch screen to casing • Already be accounted for in arm design

  22. Shock Mounting

  23. Thermoforming • CJK is aware of our project and is willing to work with us to make a successful case • http://www.youtube.com/watch?v=WL-h0HAcdFA • Demonstration at Miller Plastics in PA • Awaiting response on what type of plastics that can be thermoformed • Looking into polycarbonate, delrin and UHMW polyethylene • Need to finalize CAD design to send over to them

  24. Our BIGGEST Concern: OUR WEBSITE IS GONE!!!

  25. Questions.. Comments.. Concerns???
