BackgroundCar lanes next to youMust shoulder check, but

really?Drivers must be reminded

Motivation410,000 lane-changing related

accidents annually

Costs

All of us can relate to the danger

Vast number of cars

Good drivers want to drive more safely

6

Existing ProductsBlind spot mirror

2 mirrors to look at?

Only on very recent modelsNot widely available

Other similar products ~$500Too much

Our Solution

Increase road safety

Economical

Universal to personal cars

Accurate (rain/snow, night/summer)

Friendly toward all types of users

Sensors Wide angle (40 degrees) Should not detect past 3m (do not want to

sense vehicles 2 lanes over) Should be fairly inexpensive

Infrared , Laser, Photo Recognition, Sonar, Ultra Sound

Costly, narrow angle, range issues

13

Sensors Ultrasound Sensors meet our criteria (Wide angle +/- 20 degree,

short range 2m, low cost) Parking Sensor purchased , sensor and driver

used. Easily Installable Proven Field experience

Sensors Supposed to work up to 2.5m Reliable results at 1.5m to 2.0m Still works for most vehicles in the parallel

lane
