it is a smart wheelchair which uses voice and bluetooth commands . Also consists of temperature and heartbeat sensors for continuous monitoring by the doctor.
Nowadays the vehicle accident rate has been increasing as compared to the previous decade. This system proposes a solution to minimize the action time after an accident. It has the capability of ensuring the drivers safety along with the co-passengers and can easily be integrated with the car. The vehicle is connected to a hardware device that detects the collision with the help of a vibration sensor. The hardware device also consists of a fire sensor that senses fire breakouts. It communicates with an application in the Smartphone through Zigbee Bluetooth whenever collision or fire is sensed. If the driver doesnt want to communicate any information, he can cancel using the reset switch. Once the Bluetooth connection is established, the application would track and communicate the victims GPS location along with the patients entire medical report to their companions as well as the nearest hospital through an SMS. The application also checks the availability of the blood in the nearest blood bank and sends a notification back as soon as the availability of blood is ensured. A.

These slides use concepts from my (Jeff Funk) course entitled analyzing hi-tech opportunities to show how mobile devices are becoming more economically feasible for health care. Rapid improvements in electronics are enabling a wide variety of health-related attachments to become available for mobile phones. These attachments can analyze breath, blood oxygen levels, blood glucose, blood type, and urine and do ultrasounds. These advances will change the way health care is monitored and managed.
Patients having injuries and physical disabilities and with good mental health face a lot of difficulty when using the conventional hand powered wheelchair. This project enables an economic assembly in any existing wheelchair that enables a smart system for automated motion which can be controlled by any Smartphone. The concept particularly mentions ‘Smartphone’ which covers devices like any Android powered mobile phone which have inbuilt 3 axis accelerometer and Bluetooth Wireless technology. The functionality can be extended to other mobile devices using a suitable application. The other end of the system has a micro controller powers the DC motor for linear motion of the wheelchair. The DC motor connected to the rear wheels enables linear motion.

Medical Innovation- Top 5 Medical Technology Innovation For HealthCareDavid Stoffel
Medical healthcare technology is rapidly changing, Many in the industry have long felt overly burdened by what they consider to be an unnecessarily complex approval process. Here are five emerging technologies to watch in the year ahead.
Here we are making a project which just traces our vehicle location, in terms of its precise latitude and longitude and then send it to a mobile number (as per our requirement). This project consists of three main devices which are :- (i) Arduino UNO, (ii) GPS module (Neo-6M), & (iii) GSM- 900A.These all three devices will be going to be installed in the vehicle to which we want to trace. Initially what happened that we make a program in arduino (in C language) regarding interfacing the GSM device and GPS device. And we also set a mobile number in the program as per our need, on which we get the info regarding its (vehicle’s) location. First of all we make a call to the mobile number which has been installed in the GSM module and then after some specific delay (as per mentioned in the program) we get a sms regarding the exact latitude and longitude of the vehicle. It is done in a way that GPS device is continuously receiving the location of the vehicle from the satellite and then transferring to the arduino board, from where we send it to the required mobile no. And hence in this way we can easily get info regarding the exact location of the vehicle. Once the message has been sent to the predefined mobile no. the GSM gets deactivated and the GPS gets activated. Thus we can easily trace our vehicle. Vehicle Tracking System (VTS) is the technology used to determine the location of a vehicle using different methods like GPS and other radio navigation systems operating through satellites and ground based stations. This system is an important tool for tracking each vehicle at a given period of time and now it is becoming increasingly popular for people having expensive cars and hence as theft prevention and retrieval device.

The project we have undertaken is “Solar Inverter”. A solar inverter, or PV inverter, converts the direct current (DC) output of a photovoltaic solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-line electrical network.
A solar inverter, or PV inverter, converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. It is a critical component in a photovoltaic system, allowing the use of ordinary commercial appliances. Solar inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.
