  9. Catch-a-Buzz • This system is designed for users to participate in games like a quiz bowl. Users would be able to hit a button on a remote unit that would transmit the response wirelessly to a center console that indicates who responded and keeps track of a scores. Alternately user can respond to a multiple choice question, the console would then indicate the correct answer and score. • Buzzer system • Allows for 1 to N remote units • Master console that indicates responses and team scores • Two operation modes: • First unit to respond • Correct answer multiple choice • Display team scores either on LCD or TV out • Why is this a good project? • Large target market: schools, organizations, weddings • Easy to use for people, simple remote interface • Utilizes the skill of each team member fully

  11. RF controlled Belaying Machine • The RF controlled belaying machine is a device intended for use by rock climbers in an indoor rock climbing facility. The primary objective of this device is to substitute the use of a human belayer through the safe use of a belaying machine. • The key performance aspect of this device is that it eliminates the use of a belayer when indoor rock climbing. It delivers all control to the climber through a simple RF module which controls the various modes in which the machine can be used. • The base/motor drive is powered by a typical 120V power outlet. The remote unit is Li-polymer powered and is recharged through a unit positioned on the base/motor drive. The user interface consists of a pushbutton type user interface with confirmation LED’s for each command. The user interface controls the different modes of operation: belay, slack adjustment, stop and rappel. • This project is a good fit for the team due to it’s interesting and practical nature. An RF controlled belaying machine does not exist, it would be the first of it’s kind. It’s marketability is very plausible for all indoor rock climbing centers.

  13. Enroute - Overview • Transit Notification System • This system consists of units at each bus stop that communicate with a remote on every running bus. This allows a bus to only stop at a bus stop if notified by the unit at the station. The users notify the bus via push buttons on the station transceiver. Both Transceivers are programmable via a keypad on their respective units. The station transceiver also contains a taxi call but that sends a request to a server via a network interface.

  14. Enroute - Features • Station Transceiver Unit • Ability to request different busses via push buttons • Programmable via keypad • network interface for taxi notification and confirmation • Powered by 120V transformer • Bus pickup notification • Bus Transceiver Unit • LCD display for stop notification • Communicates with stations via RF transceivers • Programmable via keypad • Powered by 12V DC to DC transformer • Post-pickup cancellation

  16. Enroute - Justification • Why is this a good project? • Large target market: useful in any city with a public transit system. • No competitive products exist: Unique to the transportation market • Easy to use for people, simple interfaces on both ends • Reduces ride time and thus money • Convenience of notifying taxies • Fully utilizes the skill of each team member

  17. Enroute - Product Selection Process • Major Risks • Too many blocks - overly complicate design • Why were other projects rejected? • Other projects were not as closely related to our individual expertise • Mechanical challenges with the Belaying machine • Lack of marketability for the Catch-A-Buzz product • Product Selection • Project selection was unanimous
