Power and Delay Analysis of Flip Flop Using Pulse Control Method
Full text linkThe past few years, increasing difficulty in integration can be solved by low power, which is very important and also choosing flip-flop solves the challenges like low power. In this paper, we design and compare the power problem of various indirect pulse triggered flip flop are examined. It can be attained by reconstructing the lower part of Single-ended Conditional Capture Energy Recovery (SCCER) design and by employing the control pulse scheme. The results after the simulation derives transistor count and power required are significantly reduced in the proposed design over existing design
Server Based Wireless Motion Detection System Using PIR Sensor
Full text linkDetecting human movement plays a vital in this industrial era where it can be effectively used in industrial sectors dealing with reactors and boilers. A server based automated system that allows only the authorized persons to enter into the hazardous zone that will avoid misguiding of the system by unknown persons. In this research article, a server based motion detection module involving PIR sensor and GSM is proposed. Here we use two modules one is digital image processing and another one is embedded system. It is used to detect any obstacle in within its field. Once obstacle will be detected camera will be on. Camera captured an upcoming image and check whether it is a human or animal, if it is a human it will compare with input database images, then easily find unauthorized person
Optimization of Classified Satellite Images using DWT and Fuzzy Logic
Full text linkThe image taken by a satellite can be enhanced in terms of its resolution based on the interpolation can be obtained by DWT. Using DWT, the image at the input is divided into several sub bands and the speckle noise is also removed. Thereafter, the high-level images and low-level image at the input can be combined, to produce a better image applying IDWT. An intermediate stage for approximating high level is proposed here. The variation in detection approaches for SAR images are done by using image fusion strategy and novel fuzzy clustering algorithm. To retrieve an enhanced image, wavelet fusion directives are considered to combine the wavelet coefficients. A fuzzy C-means algorithm is proposed for identifying the altered and unaltered regions in the combined difference image
Optimized Adaptive Huffmann Coding For Paper Reduction in OFDM Systems
Full text linkThe main defect of OFDM systems is its high peak-to-average power ratio (PAPR). To decrease PAPR, Adaptive Huffman coding is essential. Encoding is transferred by two encoding techniques Huffman coding and Adaptive Huffman coding at the transmitter side. Mapping is done by QAM 16 and PSK 16.The PAPR results of Huffman and adaptive Huffman coding with QAM 16 and PSK 16 is compared. Simulation results shows that the Adaptive Huffman coding along with QAM 16 produces fruitful results in comparison with Huffman coding and adaptive Huffman coding with PSK 16
Design and Analysis of Low Power Energy Efficient Braun Multiplier
Full text linkDesigning of Braun multipliers using various hybrid full adder circuits are described in this paper. In DSP and communication systems, multipliers are the main power consuming elements. Dynamic power dissipation contributes a lot to power consumption in CMOS logic. Braun multipliers employing Row bypassing techniques are designed to minimise the switching activities which aids in reducing dynamic power consumption. Full adders constitute a most vital part in multipliers. In this paper, Braun multiplier is designed using three different hybrid full adders .Area and power consumption of the resulting circuits are compared and analysed. The Braun multipliers are implemented and simulated using Tanner spice
Power Theft Identification Using Embedded System
Full text linkToday, power theft plays the key role in transmission losses of electricity from the generating station to the consumer end. About 30% of power produced is being theft. Though the electricity boards know that there is power theft in the area under their vigilance, they are not able to locate the area or location of theft. So, to identify the power theft and to communicate to the EB there needs a system to be developed. Here comes the system developed by us which will find the power theft if it happens and sends the information about the place of the theft to the nearby Electricity Board
CMRR Boosted Instrumentation Amplifier for Biomedical Application
Full text linkThis research paper discusses about a design of an amplifier for its use in an Analog Front End for Biomedical signal acquisition. The design of an AFE is also specific to the signal of interest. This paper deals with the design of an Analog Front End using 180nm process. An amplifier is a key component of an AFE. For instrumentation amplifier to satisfy theoretical results the OPAMP used must be close to ideal. The simulations are performed using TANNER EDA tool
Leakage Power Minimization Using Gating Technique In FPGA Controlled Device
Full text linkFPGA based controlled devices are widely used in integrated chip sector provided the power consumed by such devices should be low. Leakage power takes vital part in contributing towards the total power consumption. This research work concentrates in proposing a power gating technique based on look up table approach. The novelty of this approach is that common look up tables are employed for asynchronous architectures for each leaf node. Due to this the leakage power and the total area overhead can be minimized. The proposed architecture is simulated through M-Power analysis and simulator tool for leaf nodes and efficiently utilizes H-tree methodology to minimize area. The reduction in number of look up tables leads to 45% to 50% reduction in leakage power of FPGA device

The Wassily chairs are the mobile chairs that facilitate the movement of the user in pre-functioned places. This is an intelligent vehicle which has all the feasibility for the usage of the physically impaired. This mobile chair replaces the traditional gear system with the keypad system to reach the destined places and to locate the things in the destined places. This makes the vehicle smart and user-friendly augmenting the viability to carry out their day to day activities. It has an additional feature, the automatic airbag system which provides hip bone protections
An Intelligent Auto-Tracking Vehicle
Full text linkWith gas prices at historic highs and fuel-efficient cars in vogue, the time might be perfect to introduce the Smart Car. The chief goal of this paper is designing a smart car with transportation capabilities of a traditional car. The project introduces ways of making car to sense the environment and navigating on its own. The algorithm is implemented using a freescale’s32-bit MPC5604 microcontroller and CODEWARRIOR (IDE) software. It is based on Free Ranging on Grid Technology (FROG) which uses Automated Guided Vehicle Systems (AGV), which are driverless cars. An AGV is a robotic device that follows marks in the floor. The fundamental requirement for this smart car is to sense the given track in a most efficient and in a considerably very short time. The actuators used for lateral and longitudinal control were a servo and a D.C motor respectively. Thus a model car can be designed with electrical, electronic and mechanical systems and can be travelled in smoother and faster way in the track by electromechanical control. In such automated systems, vehicles are programmed to have various features to ensure smooth car navigation, traffic signal control, cameras to monitor and systems to maintain appropriate speed limits etc. Thus in future, this kind of smart cars acts as an intelligent transport system
