    Diseño y construcción de un dispositivo para la alerta de obstáculos (DAO)
    (2014-04-18) Herrera-Velásquez, A. (Alejandro); Jaramillo-Morales, R (Roberto)
    This paper presents the development of a portable electronic device for blind people. It is composed of an ultrasonic pair (emitter-receiver), and lead by a microcontroller. First, an emitter block generates ultrasonic waves that are reflected after they had collided with an obstacle. The reflected signal is captured by the receiver. The signal is then amplified, and after a threshold comparison is made by the microcontroller, an output is carried to the motor of a vibrator located in the patient’s waist.The systems block diagram, the programming logic, the mechanical design, and the electrical circuit schematics are presented.
