3. Problem Statement General Background: • Auto-Closing Garage Door System • Convenience for homeowner • Home security Technical Issues: • Remote transmitting • State of the Garage Door • Signal Processing • Operation of Garage Door Opener • External Lighting Circuit

4. Operating Environment • Located Inside Garage • Operational at (–) 40 to 120 Degrees Fahrenheit Conditions • Used with Chain or Screw Drive Openers • Residential Systems Only • Two-Door Garages

5. Intended Users/Uses Intended Users: • Home Owners • Family or Neighbors Intended Uses: • Automatic Closure of the Garage Door • ON/OFF Capabilities • NOT intended for Commercial or Industrial Use

6. Assumptions and Limitations Assumptions: • Installed on Residential Grade Openers Only • Power Source Maintained by the End User • Obstruction Sensors Previously Installed Limitations: • Door Opener must have external contacts • Maximum of Two Garage Doors

7. End Product Description Features: • Rail-type Residential Grade Garage Door Systems • Adjustable timer for Automatic Closure • Two Garage Door Operation • Override mode for leaving door open without timer • Can be retrofitted for state-controlled openers

8. What Has Been Done? Accomplishments: • Defined the Problem • Determined the Technical Design • Located and Received all Parts • Finished all Necessary Documentation • Implementation of the Design • Testing • Final Documentation • Oral Presentation to Industrial Review Panel

9. Possible Approaches • Building a Transmitter/Receiver from scratch vs. Buying a Fabricated Unit • Building a “Hard-Wired” Logic Circuit vs. Signal Processing • Different Types of Sensors for Input • Pressure Pad for Tire • Contact Limit Switches • Magnetic Switches • IR (Obstruction) Sensor • Light Sensor • Using Openers with Exterior Contacts vs. Determining the Internal Circuitry

10. Solution Approach Scenarios: • Leaving Garage • Returning Home • Desire to have the Garage Door Open Sensing: • Contact Switches • Light Sensors

11. Final Project Definition Functionality: • Operative in any environment • Timers • Door Timer • Lights Timer • Safety and Environmental • Light Sensor • Contact Limit Switches • Signal Processing • Micro-Controller (HC11) • Power Relays • Four-button Controller • Transmitter/Receiver • Wall Mounting

12. Research Activities Research: • Internet and Advisors • Transmitter/Receiver – located and purchased online • Relays – located and purchased online • Micro-controllers – used ISUs HC11 • Sensors – Door Store, Previous Lab Projects Free Door Opener: • Sears 1/3 H.P. Rail type - Chain driven • Manufactured in 1992 • Not Compatible with Recent Obstruction Sensors

13. Technical Approach • Garage Door Scenarios: • Hard Wired Logic Circuit vs. Micro-Controller • Design vs. Purchasing a Transmitter/Receiver Unit

18. Implementation Activities Problems Encountered: • Downloading Code to Motorola HC11E9 EVBU Board • Switched to Motorola F1HC11 Board that was used in Cpr E 211. • Important Part of Magnetic Sensors Missing • Part Built into Genie Systems. Changed to Contact Limit Switch. • Obstruction Sensors Not Compatible with Door Opener • Eliminate Obstruction Sensor as input to SGDS because of FCC Regulation in 1993.

19. Testing and Modifications Testing: • SGDS Broken into 7 Different Individual Tests • Tested as whole afterwards Test 1 – Transmitter and Receiver: • Apply Power, Measure Output at Relay Test 2 – Momentary Push Buttons: • Figure out Wiring Scheme Test 3 – Relays: • Apply 5V to Coil and use Ohmmeter to test the resistance between NO and the Com terminals

20. …Testing and Modifications Test 4 – Garage Door Opener: • Power Opener and Determine Terminal Functionality Test 5 – Light Detection Circuit: • Build Circuit from Schematic and test with a flashlight to see if the Voltage Signal disappears when incandescent light is visible. Test 6 – Contact Limit Switch: • Wire a series circuit and make sure the NO circuit changes to closed the the contact is closed. Test 7 – Micro-Controller: • Download the program to the hardware, send in input signals with a source to different pins and check the output for a signal.
