  3. Team 5: Expertise & Experience • Gideon • Shee Tong • Nathan • Kong • Naser Aldaihani • Expertise: soldering and testing Experience: internships @ Milwaukee Electronics, and Rockwell Automation. • Expertise: None Experience: None • Expertise: hydraulic electronic control Experience: GS Hydraulics 3 yrs. • Expertise: Instrumentations Experience: Oscillators, timers, and microcontrollers • Expertise: None Experience: None

  4. Team 5: Total Resources Estimation • 800 Manhours expected • $200 or key part availability for material and prototyping • As individuals, we are dedicated to making the most from the class and as a team we are pretty excited working together and contributing to each others success.

  5. Selection Matrix – Average team scores 0-100

  6. Projects under consideration Fish Tank Feeder

  7. Projects under consideration Fish Tank Feeder • There are three possible operations desired. • The fish tank project is a position sensing apparatus through IR, that once sensed, the feeders will then dispense food controlled through proper timing. • The objective of the Water Institute is to collect data that supports there understanding of fish activity.

  8. Projects under consideration Smart-Bot

  9. Projects under consideration Smart-Bot • A Smart-Bot is one that makes movement based on the programming of the interpretation of sensors. • This fully automated robot may also be used in tracking and following sensors detected on a person to cart personal belongings.

  10. Projects under consideration Room Temperature Control

  11. Projects under consideration Room Temperature Control • This project is geared towards temperature control. • Is able to moderate the temperature of an environment using a thermocouple and fans as temperature makes slight changes. • The controlling centre would be used through remote digital operation to set and shut down the system.

  12. Proposed Selection Photo Sensing Blinds !

  13. Proposed Product Summary Photo Sensing Blinds ! • The blinds will be able the detect changes in sunlight from the inside and out, and adjust there direction by the use of servo motors. • The blinds will operate under direction of the CPU with proper interruption from a remote controller. • The blinds are to be fully automated to operate in timed intervals that may be set from an RF controller (optional).

  14. Proposed Product Summary Photo Sensing Blinds ! • The product will operate off of three photo sensors positioned on or around the blind. • The primary benefit of the product is to control the opening and closing of the blind and also to provide a glare free environment at low cost. • The user friendly remote control will be made available for manual operation so that all may enjoy!

  15. Proposed Product Summary Why we chose the Photo Sensing Blinds Project ? • Overall, this project incorporates the expertise available of all of the group members. • The project completion is obtainable within the allotted time for the class. • This project was ideal because of the possibility of funding from the “Discovery World” and the chance upon completion, display of the project at there facility.

  16. Major Risks taken • Having made agreements with “Discovery World”, gives a sense of obligation that will be a challenge. • Added product reliability and durability for display. • Programming limitations may prohibit our final prototype’s range of ability. • We must provide a precise cost determination due to funding and might not get a second chance.

  17. Project Selection Why we rejected other ideas ? • Other projects required more understanding of resources that were beyond our present scope (i.e. smart-bot and the fish tank). • Repetition. • No funding was available. • The other projects just didn’t offer a large enough range of product use and availability.

  18. System Level Requirements Performance Requirements: • Auto mode: consistent updates from the light intensity read sensors which cause specific angle adjusts to be made on the motors through proper programming. • Manual mode: fast responsive user interface through remote control†, with push-button user settings to change orientation of the blinds. • Sleep mode: goes into hibernation to the extent of timers manual setting. • Off mode: option for the user to turn off the blind control system completely † Radio Frequency remote control is optional.

  19. System Level Requirements Standard Requirements: • Temperature: -40°F -> 85°F • Humidity range: 0-100% • Input voltage: 120V • Power: 20W

  20. Block Diagram Description † Radio Frequency remote control is optional.

  21. Block Interface Signals • Power Supply – Shee Tong Lee Convert from a 120VAC @ 60Hz source into a 12 VDC Output +/- 12 V and +5 to the sensor and controller Output – 12 V to the DC Motor

  22. Block Interface Signals Controller – Kong Meng Yang - Analog input from photo resistor circuit, make computations, and output a signal to the motor (PWM). - Digital inputs from remote user interface, make decisions, and give output to display and motors.

  23. Block Interface Signals • Motors – Nathan Schultz • A digital input of 12Vdc nominal from the power supply will drive the motor op. • Wiring from the main PCB will determine Bi-directional operation. • PWM supplied output will be supplied from the MPU and interfaced trough a H-bridge to operate the motor. Closed-loop Control

  24. Block Interface Signals • Inputs from H-bridge will control through PCB trace on remote location. • Power cable from supply to drive H-bridge. • Closed-loop Control operation trough wiring to MPU.

  25. Block Interface Signals Photo Sensor (Block 4) – Gideon Afolayan Block 4 senses the intensity of the light and sends an analog signal to the controller To that effect. Block 4 gets an input of 5V and 12V from the power supply (Block 1). Block 4 has an output interface with the input of the MPU (block 2) and supplies an analog voltage supply within the range of 0V and 5V Photo Sensor / MPU

  26. Block Interface Signals • Remote User Interface – Naser Aldaihani • Powered by 9v DC battery • Digital output to MPU • Analog output from the remote to the circuit board

  31. Ethics & Intellectual Property Ethical or Societal Issues • User may not be harmed or injured if the product failed. • User should be cautious of body parts on and around equipment. • Injury or harm due to product failure can be prevent by doing adequate safety testing directly in the product design. • Faulty or flawed Engineering may resulted in public harm. • Faulty or flawed engineering can be prevented by insuring that the product designs comply with maximum safety standards. • Engineering of product reliability and durability is crucial for display atmosphere.

  32. Three applicable patents: • Patent number:07/753,811 Title: Russel J. Jacobs Date: September 3, 1991 • Patent number:09/610,066 Title: Gary E. Will Date: July 5, 2000 • Patent number:06/248,223 Title: Jean Bullat Date: March 27, 1981
