Abstract

Objectives: This paper describes the method of measurement of glucose concentration in the human blood non-invasively using the near infrared optical technique. Methods/Analysis: In recent medical practice, the concentration of glucose in blood is measured using an invasive techniques which generally involves puncturing finger. In generic few ml of blood whereas in recent practice less than a drop of blood is taken out and passed through the standard chemical tests to measure glucose concentration. These methods are expensive as well as painful. The frequent finger puncturing causes calluses on the skin and also increases the risk of spreading infectious diseases. Findings: So, the development of a non-invasive blood glucose measurement system will be boon to the diabetic patients. This paper describes the method of blood sugar measurement in the human blood non-invasively using the painless near infrared based optical technique. The designed system consists of LED emitting signals of 940 nm wavelength. These optical signals are sent through the fingertip and reflected signals are detected by phototransistor placed beside the LED. The glucose concentration in the blood is determined by analyzing the variation in the intensity of received signal obtained after reflection. The results obtained from the designed system shows the feasibility of using NIR based non-invasive method for the measurement of blood glucose. Applications/Improvements: The described system is majorly useful for diabetic patients. The measurement accuracy of the proposed system can be improved by incorporating it with noise filtering techniques.

Abstract

In modern day scenario due to heavy traffic, it is always significant to find a free parking slot to park a vehicle in crowded area. The main motto of this project work is to find the available parking slot to park the vehicle and the current status of free parking slot should available on user mobile application even before visiting the parking area. In this paper the image processing technics is adapted to find the free parking slot. Camera captures the image of parking lot and the image is analyzed to find the possible number of free parking slot. Contour method is implemented to find coloured circle on parking lot which indicate the availability of slot. The various modifications like converting RGB images to HSV are performed on Open CV platform which is installed on Raspberry pi. As Raspberry pi is used it is easy to bridge image processing task and internet connectivity over server. It is efficient to send data over internet in small duration of time. This system provides the proficient way for the user to park vehicle without any guide. This system can be implemented in any public parking place, shopping complex, corporate offices etc. This method can be easily implemented in a short period of time and does not require regular maintenance.
