This Project proposes a vehicle-to-vehicle communication protocol for cooperative collision warning. Emerging wireless technologies for vehicle-to-vehicle (V2V) and vehicle to-roadside (V2R) communications such as DSRC (Dedicated Short Range Communications) are promising to dramatically reduce the number of fatal
roadway accidents by providing early warnings. One major technical challenge addressed in this Project is to achieve low-latency in delivering emergency warnings in various road situations. Based on a careful analysis of application requirements, we design an effective protocol, comprising congestion control policies, service differentiation mechanisms and methods for emergency warning dissemination. Simulation results demonstrate that the proposed protocol achieves low latency in delivering emergency warnings and efficient bandwidth usage in stressful road scenarios

An accident is a deviation from expected behavior of event that adversely affects the property, living body or persons and the environment. Security in vehicle to vehicle communication or travelling is primary concern for everyone. The work presented in this article documents the designing of an accident detection system. The accident detection system design informs the police control room or any other emergency calling system about the accident. An accelerometer sensor has been used to detect abrupt change in g-forces in the vehicle due to accident. When the range of g- forces comes under the accident severity, then the microcontroller activates the GSM modem to send pre-stored SMS to a predefined phone number. Also a buzzer is switched on. The product design was tested in various conditions. The test result confirms the stability and reliability of the system

Advanced Rural Transportation Systems (ARTS) provide information about remote road and other transportation systems. Examples include automated road and weather conditions reporting and directional information. This type of information is valuable to motorists travelling to remote or rural areas. This has been widely implemented in the United States and will be a valuable asset to countries like India, where rural areas are widely distributed

In the hospitals when any major operation is performed, the patient must be in anesthetize condition. If the operation lasts for a long time, say for suppose for 5 or 7 hours, complete dose of anesthesia cannot be administered in a single stroke. It may lead to the patient’s death. If lower amount of anesthesia is administered, the patient may get up in midst to avoid this, the anesthetist administers few milliliters of anesthesia per hour to the patient. If the anesthetist fails to administer the anesthesia to the patient at the particular time interval, other Allied problems may arise.To overcome such hazardous problems the design of an automatic operation of an anesthesia machine based on a micro-controller is effective. In this system provided syringe infusion pump along with the microcontroller . The anesthetist can set the level of anesthesia in terms of milliliters per hour to administer anesthesia to the patient. After receiving the signal from the temperature sensor heart beat sensor and respiration sensor , the microcontroller controls the signal to the desire level and fed into the stepper motor to drive the infusion pump in proper manner. The anesthesia is administered to the patient according to the stepper motor rotation.This particular paper will be very much useful to physicians to see the current position of anesthesia of the patients. If the level of anesthesia is decreased to lower level (set value), the alarm will be initiated to alert the physician to refill the anesthesia in the Syringe Pump to continue the process

SixthSense is a wearable, gestural interface that augments our physical world with digital information, and lets us use natural hand gestures to interact with that information. SixthSense brings intangible, digital information into the tangible world, and allows us to interact with this information via natural hand gestures. SixthSense frees information from its confines, seamlessly integrating it with reality, thus making the entire world your computer. The SixthSense prototype comprises a pocket projector, mirror, and camera worn in a pendant-like mobile device. Both the projector and the camera are connected to a mobile computing device in the user’s pocket. The system projects information onto the surfaces and physical objects around us, making any surface into a digital interface; the camera recognizes and tracks both the user's hand gestures and physical objects using computer-vision-based techniques. SixthSense uses simple computer-vision techniques to process the video-stream data captured by the camera and follows the locations of colored markers on the user’s fingertips (which are used for visual tracking). In addition, the software interprets the data into gestures to use for interacting with the projected application interfaces. The current SixthSense prototype supports several types of gesture-based interactions, demonstrating the usefulness, viability, and flexibility of the system. The current prototype system costs approximately $350 to build.

This paper presents a hardware efficient architecture for generating sine and cosine waves based on the CORDIC (Coordinate Rotation Digital Computer) algorithm. In its original form the CORDIC suffers from major drawbacks like scale-factor calculation, latency and optimal selection of micro-rotations. The proposed algorithm overcomes all these drawbacks. We use leading-one bit detection technique to identify the microrotations. The scalefree design of the proposed algorithm is based on Taylor series expansion of the sine and cosine waves. The 16-bit iterative architecture achieves approximately 4.5% and 6.7% lower slice-delay product as compared to the other existing designs. The algorithm design and its VLSI implementation are detailed.

Now-a-days various Digital Signal Processing systems are implemented on a platform of programmable signal processors or on application specific VLSI chips. Coordinate Rotation DIgital Computer (CORDIC) algorithm has turned out to be such kind of programmable signal processor. In recent times, it has been a widely researched topic in the field of vector rotated Digital Signal Processing (DSP) applications due to its simplicity. This paper presents the design of pipelined architecture for coordinate rotation algorithm for the computation of loop performance of complex Digital Phase Locked Loop (DPLL) in In-phase and quadrature channel receiver. The design of CORDIC in the vector rotation mode results in high system throughput due to its pipelined architecture where latency is reduced in each of the pipelined stage. For on-chip application, the area reduction in proposed design can is achieved through optimization in the number of micro rotations. For better loop performance of first order complex DPLL and to minimize quantization error, the numbers of iterations are also optimized.

The purpose of the project was to design and build a 1/5th scale Segway cart. The cart was modeled after a two wheeled transportation device that uses sophisticated electronics to balance. The cart was designed to follow a line as fast as possible while still keeping a load balanced atop. The cart was limited to several maximums; a height of 6 inches, a mass of 1-kg, wheel diameters between 0.5 and 6 inches, and removable handlebars from 7-9 inches. The cart also had to support a cylindrical mass with specifications of, a mass up to 2-kg, and a diameter of up to 6-inch. The cart was designed to rock on its wheels over a range of 60 degrees forwards and backwards as well as to follow a black electrical tapeline on a light colored floor. The cart was expected to be self-contained including the power source. With the above design constraints, the cart was then designed to be lightweight, structurally strong enough, inexpensive, and to follow the specified path. The cart was constructed of hollow aluminum tubing, which made up the frame. The tubing was soldered together. The cart used a spinning hanging mass attached to a potentiometer to sense the angle of tilt. By measuring the change in voltage in the potentiometer as the cart tilted, the balancing of the cart was regulated. Photo sensors were implemented for detecting the black electrical tape and to start the cart in motion

The chair will also sense the obstacles in front of it and gives a beep sound.

This paper presents a new approach for the high performance and hardware efficient design of coordinate rotation digital computer (CORDIC) processor structure. The proposed design approach completely eliminates the ROM requirement of constant arctangent values. Furthermore, efficient designs of carry look ahead adders (CLAs), exploiting one input as constant, in the angle adder/subtractor datapath speeds-up the computation while maintaining regularity. The proposed architecture is implemented in FPGA as well as in 180nm standard cell library. The proposed implementation has about 39% delay improvement in FPGA and about 34% delay improvement in standard cell technology as compared to basic structure. About 47% power savings has been achieved in the proposed structure.
