چکیده
This paper presents a study on the effect of glittering and reflective objects with different colors to the output voltagedistance characteristics of Sharp GP2D120 IR Sensor, which operates by employing the principle of single point triangulation. The study was conducted by using a compact disk and plastic materials with four different colors, in which the distance for each of them was measured by a Sharp GP2D120 IR Sensor mounted on a constructed experimental setup. The results obtained shows the output-voltage-distance characteristics which indicate that; the white color plastic is having the highest level of reflectivity, followed by gray, transparent and black color objects, and compact disk as a glittering object is seemed to be having the lowest level of reflectivity.

Conduction and Dead-Time Voltage Drops Estimation of Asymmetric Cascaded H-Bridge Converters Utilizing Level-Shifted PWM Scheme
Linear AC power supplies can be replaced by their nonlinear switching counterparts due to the lower voltage drops and higher efficiency and power density of switching-mode inverters. Multilevel cascaded H-bridge (CHB) converters are the preferred inverter structure because of modular configuration, control, and protection. The output voltage quality in CHB converters depends on the number of ou...
