Abstract. Arithmetic operations are important and most commonly used functions in VLSI applications. 1-single bit full adder digital circuit is the building block that performs the operations such of addition, subtraction, multiplication, etc. Designing, Implementation of single bit full adder circuits in nm submicron process and 45nm deep submicron process are evaluated in this paper. Three adder circuits considered are Conventional adder, Mirror adder and transmission gate logic adder are evaluated in this paper. Schematic and Layout of all three adder circuits in both micron process are administered with D.C and pulse inputs. Evaluation of powerdelay product, parasitic capacitance and comparison between performance of adder circuits in both process are asserted. The adders are Modeled using EDA-Electric tool and LT spice simulation software.

Sanitization with human efforts is not an easy task. Chances of contracting infections increases which leads to additional spread of bacteria. Currently, normal cleaning robots are used in most of the places but looking at the current situation the sanitization techniques need to be improved. The robot uses radiation of UV rays to kill the microrganisms. It gives a live video streaming of its surrounding using a Wi-fi based camera. With the help of Bluetooth module and android mobile, we can control the movement of the robot inside the room without being physically present. It is built with PIC Microcontroller and Ultraviolet-C (UVC) Sanitization LED. UV-C has bandwidth range of 200-280nm and is most powerful when it comes to killing pathogens in the room. This allows us to sterilise the room effectively. By killing the germs, the UV light restricts their multiplication by destroying their reproductive system. Thus use of this robot lowers the threat of infection, cost of traditional cleaning and sterilisation and increases security in medical facilities. Thus, we are trying to implement a more efficient way of sanitization by building a Low cost UV sanitization Robot which can be used in small clinics and for household purpose.

Wakefulness of a driver is an extremely important factor that needs to be continuously monitored.. A drowsy driver can be a cause of several mishaps and accidents on highways which could lead to loss of money, physical injuries, and the most important, loss of human life. Drowsiness detection system is a car safety technology that helps to prevent and thus reduce accidents caused by the driver getting drowsy. The system is designed for four-wheeler vehicles (or more) wherein the driver’s fatigue or drowsiness is detected and alerts are generated. The proposed method will use a USB camera that captures the driver’s face and eyes and processes the images to detect the driver’s fatigue. On the detection of drowsiness, the programmed system cautions the driver through an alarm to ensure vigilance. The proposed method consists of various stages to determine the wakefulness of the driver.
