Handicapped Parking Space Sensors

Some students from the Instituto Tecnológico de Hermosillo have developed an alarm that will sound when someone parks in a handicapped parking space. Handicapped people will be the only ones with the transmittors to turn off the alarm which will sound 13 seconds after someone parks in the handicapped space.
The city is hoping within the next 20 months to install these sensors in the downtown handicapped parking spaces. The first one has been placed in front of the Consejo de Discapacitados.
If I understand correctly there was some kind of contest and the students of the eighth semester of careers in Industrial Engineering and Engineering Systems were the winners and they also competed at a regional level and won that also.

A good idea in my mind as long as they are not vandalised.
