Engineering Design Project Summary

Technology students researched, designed and constructed a cell phone transmission detection / warning system for integration into a prototype dashboard.  Whenever a cellular transmission is detected from the driver while the vehicle is engaged in any gear, the unit interrupts the audio system, beeps and provides a heads up warning message to look ahead. The specially designed antenna located near the steering column has a range of only 24 – 30 inches, which allows other passengers in the vehicle to text and use their cell phones at will.   The microprocessor controlled system, programmed by the students, monitors the electro-magnetic radiation detector circuit for cellular transmissions from the driver only.  This only occurs when the transmission is engaged in any gear except Park.  When in park, the detector is disabled.  The desired goal is not to prevent or block cellular use, but to eventually make the driver conform to good driving habits by constant interruptions of the audio system and warning messages.  A digitally programmed message plays over the speakers in the dashboard once triggered.  The message states “Heads UP! Please look ahead…  Cell phone use while driving can result in serious injury and death to you and your passengers.  Judges at Seven Springs were highly impressed by this innovate, creative and highly technical project. This message was conveyed to the students. 

Electronics research and Experimentation

The goal is to experiment with ultrasonic waves and how they can be used to help visually impaired persons navigate through a public building.  A solution summary is as follows.  A portable clip on unit was designed for the impaired person to clip onto a belt, etc.   When the unit is turned on, an ultrasonic wave is emitted at a soft frequency of 12K hertz, so the individual knows the unit is activated but it is unlikely to be heard by others nearby.    As the individual walks through a public building,  ultrasonic receivers mounted in wall  units are strategically located at the entrance,  the beginning and end of hallways,  etc, that will provide an audio map of the vicinity to guide individuals to offices, classrooms,  restrooms,  nurse,  gymnasium,  cafeteria etc.  Once the person is within 10 feet proximity of a wall mounted unit, the ultrasonic wave is detected and triggers a digitally stored preprogrammed message to be played through an amplifier for the individual.  The units use transceivers to send and receive ultrasonic waves that can’t be heard by others.   Experimentation involved controlling frequency of ultrasonic waves, controlling distance of ultrasonic waves, determining the reflection distance off walls,  and determining the divergence angle of emitted waves  for the purpose of  placement of the wall mounted units.
