Electrical and electronic circuits

The aim of this thesis is investigate and design a small antenna which can be embedded onto a Polyethylene substrate (used for making roof tiles). The antenna can be used to harvest ambient energy by connecting it to a rectifier. Due to the dimensional constraints of a roof tile as well as the materials used, there are limitations imposed on the antenna size, and thus the radiation efficiency and bandwidth often become a limiting factor in the overall performance of the system.

Modeling and simulation of dynamic systems is Pham Huy Hoang Electromotive force (emf) voltage (electromotance): is that which tends to cause current (actual electrons and ions) to flow, is the external work expended per unit of charge to produce an electric potential difference across two open-circuited terminals.

Sensor used in this project is MOC 7811 from Motorola. This is a slotted coupler/interrupter device. In each revolution as the beam is interrupted, the sensor generates a positive pulse. Microcontroller will execute interrupt routine, When a pulse occurs. Interrupt routine measures the total time taken for one revolution, divides it by 120, and stores the result into another timer, Configured in auto-reload mode. Now, the timer overflows after tiny intervals of time. Each time it overflows, next stored value is called from the lookup table, and displayed....
