This paper discusses the design of micro power Sigma-delta modulator with GA based oversampling technology. This Sigma-delta modulator design is paid special attention to its low power application of portable electronic system in digitizing biomedical signals such as Electro-cardiogram (ECG), Electroencephalogram (EEG) etc. [1]. A high performance, low power second order Sigma-delta modulator is more...
Millions of road users and pedestrians are killed in traffic accidents each year. The need to increase road safety is one of the major concerns, and the better way to increase safety is to develop systems which are able to automatically drive. The authors have tried to extract the information of sharpness of curves on the road and have presented the system which will provide the intelligent speed...
Limits to precision impose limits to the complexity of analog circuits, hence fuzzy analog controllers are usually oriented to fast low-power systems with low medium complexity. This paper presents a strategy to preserve most of the advantages of an analog implementation, while allowing a marked increment in system complexity. A digitally-programmable analogue fuzzy logic controller (FLC) is presented...
International statistics shows that a large number of road accidents are caused by driver fatigue. Therefore, a system that can detect oncoming driver fatigue and issue timely warning could help to prevent many accidents, and consequently save money and reduce personal suffering. In this proposed system security camera can be used that points directly towards the driverpsilas face and monitors the...
The international statistics shows that a large number of road accidents are caused by driver fatigue. Therefore, a system that can detect oncoming driver fatigue and issue timely warning could help in preventing many accidents, and consequently save money and reduce personal suffering. The authors have made an attempt to design a system that uses video camera that points directly towards the driverpsilas...
The VHDL-AMS based fuzzy logic controller for movement control systems is discussed here. The designs have been carried out in the digital domain with HDL. The basic components of the fuzzy logic controller are designed using VHDL-AMS. The proposed work focuses on control of speed with respect to input parameter such as Alignment & distance with triangular membership functions. This is beneficial...
This paper gives the information of Flexray protocol, Flexray is a new standard of communication between electronic modules installed in a vehicle. The protocol is based on mechanisms known from telecommunication networks coupled with real time requirements. Its architecture containing Series of FSMs, watchdogs, bus guardian block etc. This paper discusses FPGA implementation of Flexray controller...
