The widespread use of airborne vehicles and its growing applications in various domains can be attributed to their ability to operate in inaccessible areas, thus decreasing the human loss in major accidents, and making access easy to dangerous conditions. These pilotless airborne vehicles with some remote sensing techniques involved in it, are emerging as a new technology. The airborne vehicles are enduring, cost effective and also provide a reliable platform for surveying. Consequently, small airborne vehicles, here Quad copter, equipped with sophisticated components can capture and transmit the image or video to the Data Base. They are sent for processing and made accessible to the Geographical Information System (GIS), where further analysis is done for the proceedings of the rescue operation. This application finds a great utility predominantly in industries and military.

BACKGROUND OF THE STUDYReaction time is the time taken to respond to a stimulus or change in the environment. It is a method to assess the time taken from the perception of a stimulus followed by mental processing for a motor response. Reaction time in various day to day activities as in driving a car is very important. Brake reaction time (BRT) is the time taken for the driver to respond to visualize an object and to press the brake pedal. It is affected by many features like age, gender, neuromuscular disorders. OBJECTIVE OF THE STUDYStudy has been undertaken to compare the BRT in male and female drivers and to analyze the effect of sex difference on Brake reaction time. MATERIALS & METHODSMale and female subjects between the age group of 25 -35 years with driving license were included. Study is conducted in a stationary car. An in-house built; braking timer is fixed to the electric circuit of the braking system in the car. This device is wirelessly connected to the reaction time software installed in the laptop. The subject is instructed to press the brake pedal when the light changed from red to green in the laptop screen. 5 readings are taken and the mean BRT is recorded. STATISTICAL ANALYSIS & RESULTSStatistical analysis done with unpaired student t test indicates that the BRT was more in the females than the males and was statistically significant (p value -0007). CONCLUSIONGender difference has a significant effect on BRT and reaction time in female is longer than for the males.HOW TO CITE THIS ARTICLE: Ashok J, Suganthi V, Vijayalakshmi I.
