  16. Sail Away The Challenge • Design a sailboat that… • Has the smallest sail area possible,but still • Travels the length of the trough in less than 5 seconds, and • Support a payload of 200g

  17. Sail Away Test Procedure Goal 1: Smallest Sail Area Possible. Goal 2: Travel Time < 5 seconds. (without sinking!)

  18. Actividad 3:Biométrica de la Mano(Hand Biometrics) Measurement and biometric technologies for identificationand security applications Christopher LesterCoralí Ferrer

  19. Hand Biometrics Objectives • Learn about biometrics technology • Learn about engineering product planning and design • Learn about meeting the needs of society • Learn about teamwork and working in groups

  20. Hand Biometrics What is a biometric? • Measurement of a physical characteristic • Examples include: • Fingerprints • DNA • Retinal pattern • Hand dimensions

  21. Hand Biometrics Properties of a biometric • Universality – each person should have the characteristic. • Uniqueness – how well a biometric separates individuals from others. • Permanence – how well a biometric resists aging, variance over time. • Collectability – ease of acquisition, measurement. • Performance – accuracy, speed, and robustness of technology used. • Acceptability – degree of approval of a technology. • Circumvention – ease of use of a substitute.

  22. Hand Biometrics Why use a biometric? • Biometrics are used to match an unknown sample to a database of known samples • Criminal investigations • Biometrics are used to authenticate identities • Fingerprint computer login

  23. Hand Biometrics Your Turn • Create a database of 4 known samples from measurements of your hands • Develop a rule or algorithm by which you can: • …accpect an unknown sample and match it to an entry in your database; or • …reject the unknown sample as not appearing in the database at all

  24. Hand Biometrics Procedure – Part 1 • Work in groups of 4 • Each person gets their hand measured 2 times • You measure your own right hand • Another teammate measuresyour right hand • 1 “Testing” sample, 1 “Database” sample • DO NOT SWAP FORMS! Database Sample A___ B___ C___ D___ Testing Sample A___ B___ C___ D___

  25. Hand Biometrics Measuring a hand Medida A:Desde la punta del indice hasta el nudillo

  26. Hand Biometrics Measuring a hand Medida B: Ancho del dedo anular medido a traves del nudillo superior

  27. Hand Biometrics Measuring a hand Medida C: Ancho de la palma a traves de los cuatro nudillos inferiores

  28. Hand Biometrics Measuring a hand Medida D: Ancho de la palma desde el nudillo medio del pulgar a traves de la mano

  29. Medida B: Ancho del dedo anular medido a traves del nudillo superior Medida A:Desde la punta del indice hasta el nudillo B A C Medida D: Ancho de la palma desde el nudillo medio del pulgar a traves de la mano Medida C: Ancho de la palma a traves de los cuatro nudillos D

  30. Hand Biometrics Procedure – Part 2 • Set aside all 4 white “Testing” forms • Looking at just the 4 pink Database samples, develop a mathematical and/or logical rule that can be used to match an unknown sample to an entry in the “Database” Database Sample A___ B___ C___ D___ Database Sample A___ B___ C___ D___ Database Sample A___ B___ C___ D___ Database Sample A___ B___ C___ D___

  31. Hand Biometrics Example Rule • Let Sn=An+Bn+Cn+Dn Database Sample A___ B___ C___ D___ Compute Sn for each entry in “Database” Compute S for unknown test sample Choose Database sample with least error < 0.5 cm, Else state “No Match” S1 = 22.1cm Testing Sample A___ B___ C___ D___ Database Sample A___ B___ C___ D___ S2 = 25.3cm Database Sample A___ B___ C___ D___ S3 = 20.5cm S = 24.7cm Database Sample A___ B___ C___ D___ S4 = 24.9cm Error = 0.2cm MATCH

  32. Hand Biometrics Procedure – Part 3 • Combine “Testing” samples for entire table (8 samples) • Mix and shuffle “Testing” samples • Each group picks 2 random Testing samples • For each sample, use your RULE to determine if there is a match in your “Database” and, if yes, which entry matches

  33. Hand Biometrics Procedure – Part 3 • Fill in worksheet

  34. Actividad 4:¡Clasifícalo!(Sort It Out!) The engineering behind industrial sortingprocesses Christopher LesterCoralí Ferrer

  35. Sort It Out Objectives • Learn about engineering systems • Learn about coin manufacturing processes • Learn about teamwork and working in groups

  36. Sort It Out Sorting through History • Miners panning for gold • Quality control in food and other industries • Bottle sorting for recycling

  37. Sort It Out Different Types of Sorting • Image Processing:Off-the-shelf cameras, frame grabbers, and image-processing software used todevelop a casino-coin sorting system Digital I/O & Network Connection Frame Grabber Lighting Camera & Optics PC platform Inspection software Part Sensor

  38. Sort It Out Different Types of Sorting • Material Properties of Coin: • Current run through left coil, creates magnetic field. • Magnetic field passes through and is attenuated by coin • Right coil receives magnetic field, creates measurable current with different value depending on the coin Coin in Center Transverse line represents direction of magnetic field

  39. Sort It Out Why Coin Sorting is Needed • Mixed coins come from a variety of sources and must be sorted out before they can be redistributed • Coins from vending machines • Coins from parking meters • Also helpful to identify fake or foreign coins

  40. Sort It Out Why Coin Sorting is Needed • Mixed coins are • Sorted • Rolled • Re-circulated through banks and businesses

  41. Sort It Out Your Turn • Groups of 2 • You are a team of engineers hired by a bank to develop a machine to sort coins that are brought in by customers. • Must mechanically sort mixed coins into separate containers: • 10 x $1 • 10 x $2 • 10 x $5 • 5 x $10

  42. Sort It Out Your Turn How good is it? • 1: “Distance” performance index: • A coin that does not get sorted has maximum Derror = 3 $1 $2 $5 $10 $2 $2 $2 $5 $5 $1 $1 $2 $10 $1 $2 $2 $5 $5 $1 $10 $2 $5 $10 $2 Distance from correct binhere, Derror = 2 bins

  43. Sort It Out Your Turn How good is it? • 2: “Percentage” performance index: $1 $2 $5 $10 $2 $2 $2 $5 $5 $1 $1 $2 $10 $1 $2 $2 $5 $5 $1 $10 $2 $5 $10 $2

  44. Sort It Out Your Turn • Materials: • glue, tape, paper or plastic plates, cardboard, scissors or hole punch, foil, paper, cardboard tubes • one sample of each coin to be sorted • Design (draw) a mechanical sorter that can separate the $1, $2, $5, and $10 coins • Input: either • Parallel – all coins are inserted at start of your sorter together; or • Serial – coins are inserted at start of your sorter one at a time • Output: Each denomination of coin in its own physical container

  45. Sort It Out Your Turn • At your table, choose 2 groups to build a parallel sorter; the other 2 groups will build a serial sorter • You will have 45 seconds to allow your sorter to operate • Predict the value of the two performance indices for your design • Construct your sorting mechanism • Test it! • Can you do better?

  46. Sort It Out Conclusion • Did your sorting mechanism work? If not, why did it fail? • What were your performance index values? • What levels of error would be acceptable in: • Medical Equipment manufacturing? • Nail manufacturing? • What redesigns were necessary when you went to construct your design? Why?
