In this paper we have presented a two dimensional photonic crystal based biosensor. The structure of biosensor consists a linear waveguide with nanocavity which is used for sensing purpose, their refractive index change according to sensing material. Plane wave expansion method use to find out a bandgap. For the purpose structure band gap is 1339 to 1981nm and input wavelength is 1550nm. The simulation results have analyzed by using the finite difference time domain (FDTD) method.

Present Automobiles are being developed with more electronics for efficient operation of vehicles. Earlier vehicles were built with an analog driver-vehicle interface for indicating various vehicle status like speed, fuel level, engine temperature etc. The driver-vehicle interface provides an interaction of driver with the dashboard for monitoring various parameters of the vehicle and it is designed in a way to help the driver to drive safely and comfortably. There are two types of driver-vehicle interface i.e, analog and digital. In the existing analog driver-vehicle interface, it is tough to build an automated driving system because most of the processing for decision-making regarding vehicle control uses digital electronic devices (like microprocessors etc) and requires data to be handled in digital format. Hence there is need to develop digital driving system that uses digital data throughout the processing there by making the decision process more transparent as well as easy for design. The automated driving system built using digital interface allows the driver to switch from manual mode to cruise mode (semi-autonomous), so that the vehicle adjust itself with respect to other vehicles in motion, thereby helps in safe driving. The paper develops and implements the digital driving system for a semiautonomous vehicle to improve the driver-vehicle interface. It uses an ARM based data acquisition system that uses ADC to bring all control data from analog to digital format and visualize through LCD. This paper is based on CAN which uses embedded networking for efficient data transfer. It also takes feedback of vehicle conditions like Vehicle speed, Engine temperature etc, and are controlled by main controller. Additionally this unit equipped with GSM which communicates to the owner during emergency situations.
