A Simple Phase Shifting Technique for an Injection Locked Oscillator

Autor: M. Abdul-Niby, H. Baitie, Mamoon Alameen

Publikováno v: Engineering, Technology & Applied Science Research, Vol 6, Iss 6 (2016)
Engineering, Technology & Applied Science Research, Vol 6, Iss 6, Pp 1303-1306 (2016)

In Self Oscillating systems, locking of the oscillators can take place for injected signals close in frequency to nth harmonics of the free-running frequency. In this paper, we present a simple design for digital phase shift control by using a harmon

A Hands-Free Obstacle Detection and Avoidance System

Autor: M. Abdul-Niby, H. Mourtada, Mamoon Alameen, M. Baidoun, O. Irscheid

Publikováno v: Engineering, Technology & Applied Science Research, Vol 5, Iss 3, Pp 801-804 (2015)
Engineering, Technology & Applied Science Research, Vol 5, Iss 3 (2015)

In this paper, we present a low cost hands-free detection and avoidance system designed to provide mobility assistance for visually impaired people. An ultrasonic sensor is attached to the jacket of the user and detects the obstacles in front. The in
