Abstract:
A method for preventing a driver of a motor vehicle from using a cellular telephone while said motor vehicle is in one of a forward motion and a reverse motion, said method comprising the steps of:(a) determining a position of a gear shift lever disposed in a first predetermined location on said motor vehicle; (b) generating a first signal when said gear shift lever is moved to and remains in a position, determined in step (a), which will allow said motor vehicle to move into said one of said forward motion and said reverse motion; (c) transmitting said first signal, generated in step (b), to a means disposed in a second predetermined location on said motor vehicle for generating a reverse phase signal; (d) generating said reverse phase signal when said first signal, transmitted in step (c), is received by said means for generating said reverse phase signal; (e) transmitting said reverse phase signal, generated in step (d), for a predetermined radius from said second predetermined location while said position of said gear shift lever, detected in step (a) remains in said one of said forward motion and said reverse motion; and (f) preventing any cellular telephone transmission substantially within said predetermined radius while said reverse phase signal is being transmitted in step (e).
