    Bank security system
    (University of Management and Technology, 2014) Umair Mubashar; Hanan Ali; Abdul Mateen
    Safety always is the most important tool for proper and safe working. The benefits of maintaining a safe work environment are many, but first and foremost, safety is about what you can do to protect yourself and your workers; it’s the right thing to do. Safety was always the need but usually people don’t pay keep attention on it. The primary objective of this task is to plan and execute a bank security framework focused around microcontroller and GSM engineering which could be composed in bank, secured business locales and homes. In this framework just true individual might be recuperated cash from bank locker. We have actualized a bank security framework focused around microcontroller and GSM engineering containing all the cutting edge innovation utilizing microcontroller and GSM which can used to secure the banks by initiating them. The fundamental point of interest of utilizing principle controller and GSM is more secure than different frameworks. This framework comprises of microcontroller, vibration indicator, GSM modem, Laser, infrared, and Metal identifier, in this framework The Microcontroller controls the entire framework through GSM when any unsettling influence seems then microcontroller send the SMS to the validated individual portable number. By using this system we can manage to control the security issues automatically and efficiently.

    Switch mode 42V car battery charger system
    (University of Management and Technology, 2014) Omer Abid; Abdul Mateen; Haroon, Muhammad
    With advancement in technology loads and accessories in vehicles are significantly changing. Due to global warming and energy crises a system is required to improve fuel consumption and to regulate fuel emission. To overcome this problem power electronics can play an important role to improve vehicle’s architecture by establishing a higher voltage system of 42V using electrical components which draw less energy from the vehicle’s engine. Keeping this thing in mind, we decided to work on 42V vehicle battery charger system as our project for final year. Presently vehicle runs on 14V car battery system as this system seems to be vulnerable to support the heavy loads that are being installed with every new model of vehicle introduced in the market. Automobile industry has agreed to a new improved system that will deliver power to the heavy loads that they will require in modern vehicles. This idea was proposed after considering huge increase in the demand of new technology being installed in vehicles. Further, the true practical barriers to receiving of 42V have been designed and solved. Alternating Current is converted in to Dc with the help of switch mode power supply circuit. The circuit contains Metal oxide semiconductor field effect transistor for the switching at high frequency purpose and contains a pulse width modulation based feedback circuit that does not only drives the gate of MOSFET but also control the pulse width with any change in the input. The 42V system is designed and tested with the three batteries connected in the series.
