ECE 495 – Integrated System Design I

Sources of Information

• Inaccurate Information Gleaned from the Web Costs IT Departments Time and Money (CIO.com, 2008)

• Reported consequences of using inaccurate IT information:– 15% reported that a component didn't function properly – 3% reported complaints from customers – 15% reported bugs that were introduced to software – 5% projects that didn't get completed

Engineers need reliable information to do their jobs.

Note: This data is from a website. Do you believe it ?

Design Example – Head Impact Measurement System

• Safety of children heading the soccer ball– Concussion  a problem from heading the ball in soccer?– Does soccer ball heading cause retinal bleeding?

• It appears there is a need for a system that could monitor the forces that the head experiences during a soccer game.

Looks like we have identified a potential problem and customers for the solution (instrumentation to measure forces).Where would you start the design of such a system?

Research

• Your goal is to become an expert on the subjects relevant to your product design:– Basic scientific and engineering principles– Related technologies– Similar solutions and products

7ECE 495 – Integrated System Design I

Research Questions

• Has anyone done anything similar before?• What is the current “state of the art”?• How can I improve upon what has been done before?

What are the possible sources for this information?Where can I look for this information?

How Much Do I Trust a Source of Information?

• Journal (?)– Peer Reviewed, 4-5 expects attempt to find

errors and challenge results• Trade Magazine (??)

– Maybe the editor reviews and a peer review• Wikipedia (???)• Website (????)

– Based on the publisher or content owner – Reviewed by peers– Found in an online peer forum – Published in a periodical they trust

Finding Information - USPTO

• Patent Searches (uspto.gov)

Patent #: 5,613,681

Search terms: "tic tac toe" and strategy

A strategy game with the flavor of Tic Tac Toe embodied in both two dimensional(planar) and three dimensional (cubic) configurations. Each consists of a lattice type matrix forming a plurality of interconnected adjacent open cubes. The playing members are spherical and player differentiated by color. These player balls are inserted into the matrix alternately by the players and scoring is achieved by ball patterns; e.g., three in a row or nine in a single plane. The uniqueness in this game is the ability of the player balls to move from one cube to another in the matrix by the players forcing one ball against another. This capability dramatically increases scoring and blocking opportunities.
