GUARD Preventing Blind Spot Accident using Arduino

GUARD Preventing Blind Spot Accident using Arduino

According to the code written, every time an obstacle is detected and its position is displayed on the LCD screen, the whole screen is erased. Due to this the screen appears as if it flickers frequently. It was one of the constraints of this module. There are possibilities of cross talk when using multiple ultrasonic sensors. The ultrasonic sensors may read the signal from other sensor hence producing a wrong output [20].

Auto Range Resistor Sorter

Auto Range Resistor Sorter

automated resistor sorting machine that can function as a device for measuring and sorting the resistors that are used in laboratories with minimum human interference and increased accuracy. It appealed to us because we felt it would give us a chance to combine different fields of engineering: mechanical, electronics and computer. Essentially, herein, the concept voltage drop across a resistor is bootstrapped with the mechanical movements of servos to produce the required output. Our project provides two functions, namely- sorting and measuring of resistors which can be selected using an LCD screen and a mobile app. It accepts resistors, and sorts them into predefined bins or measures, displays the value and returns it to the user.

APPLICATION OF HMI TECHNOLOGY IN AUTOMOTIVE SECTOR.

APPLICATION OF HMI TECHNOLOGY IN AUTOMOTIVE SECTOR.

To overcome these safety problems with existing LCD screen, we propose a concept that combines human voice recognition technology with service details i.e. if driver is busy in driving then he can just click on an icon on LCD screen and there after he will get to know the service details of various parts of vehicle with human voice and there is no need for him to look at the screen. This will definitely help in decreasing the number of accidents. Currently in the proposed idea, the driver needs to give the date on which service has been carried out as a input to the system. Further in the future there is a scope that, the driver intervention can be completely removed by using some other means of automation.

Evaluation of the Factors which Contribute to the Ocular Complaints in Computer Users

Click here to download PDF version of the article !

headache (42.66%),diminution of vision for distance (34%) and watering (32%) among the asthenopic complaints in the com- puter workers of our university. A high prevalence of asthenopic complaints (46.3%) in the computer operators was also reported in a similar study [3]. A study which was performed on 385 bank workers of Italy reported the prevalence of such ocular com- plaints to be 31.9% [4]. Another study which was done in Spain found this prevalence to be as high as 68.5% [5]. In our study, the major ocular complaints which were reported in the descend- ing order were eyestrain, headache, diminution of vision for dis- tance, watering, redness, itching, burning and double vision. In our study, the female subjects used computers for lesser time periods than the males, as well as, most of them maintained a proper viewing distance from the computer screen, but we did not find any significant association with the age and gender of the subjects with these complaints.Such ocular complaints were correlated with the age and gender of the subjects in one such study [4]. The visual symptoms scores in the visual display termi- nal operators were found to be higher among the females than among the males in a Japanese study. However, they did not find any difference with respect to the age [6]. While considering the duration of the computer use, the review of literature revealed mixed pictures as far as the occurrence of the ocular complaints was concerned. One of the studies found a significant difference in such complaints and in the daily hours of the visual display ter- minal work between the workers who worked less than 6 hrs daily and those who worked more than 6 hours daily [7].
