Ramekar Brothers Obtain International Patent for Preparation of Fog Driving Device

Staff reporter

Smiraj Ramekar, a 19-year-old student with his younger brother Samruddha, a 14-year-old from Adilabad, Telangana (originally from Nagpur) received an international patent from Germany. They received the patent for the design of a device called “Fog Safe Anti-collision System” to prevent vehicle accidents on the road in a foggy and sandstorm climate. They completed the project under the guidance and assistance of “Patent Man of India” Ajinkya Kottawar along with Dr. Raju Ramekar, Radiologist, father of Smiraj and Samruddha.

Places with cool climates and hilly regions with dense fog on the road are major hot spots for road accidents for two-wheelers and four-wheelers. Maneuvering a vehicle in any type of weather can come with its own set of challenges and limitations. Maneuvering a vehicle in conditions that limit visibility, such as mist, fog, or desert storm, can be even more difficult and even dangerous.

However, several accidents can be seen during the foggy season and the driver also finds it difficult to drive the vehicles smoothly which leads to delays. In view of the foregoing discussion, it is clearly disclosed that there is a need for a vehicle fog safe anti-collision system.

Smiraj and Samruddha told ‘The Hitavada’: “We have found a vehicle anti-fog collision avoidance system, the system includes at least one camera installed in the front of a vehicle to capture real-time video of the area in front of the vehicle.A number of sensors coupled to the vehicle to detect nearby vehicles, objects and people at a predetermined distance from it and a control unit to display clear video on a head-up display and to alert a driver of the vehicle’s proximal distance to vehicles, objects and people to avoid collisions and accidents, with the captured video being pre-processed by the control unit to display a clear image.”

The system includes a PIR (Passive Infrared Sensor) and an ultrasonic sensor to detect nearby vehicles, objects and people at a distance of approximately 5m to 10m. The driver is alerted by a speaker built into the vehicle and the intensity of the alert increases to warn the driver of the collision. The system includes a crash detection sensor placed in a vehicle to identify the crash and thereby a current location along with a crash alert is sent to one or more registered numbers for assistance, the recorded numbers including parent, police, rescue team, nearby hospital. The system helps to detect the current location using a GPS module and the current location along with the accident alert is sent to one or more registered numbers through one of the GSM or GPRS modems. The system includes a storage memory in the vehicle to store video captured during an accident, so that the driver can prove the reason for the accident. Preprocessing of the captured video includes changing the brightness and contrast level settings to clearly see the object that is present from afar in a low visibility area, with contrast adjustment achieved using time noise removal real world using a neural network to obtain the necessary levels of visibility. The camera is capable of capturing wide-angle videos, ranging from 180 to 270 degrees. The camera lens is coated with an anti-fog film to prevent fog buildup on the camera lens.

The present invention generally relates to a vehicle anti-fog collision avoidance system comprising at least one camera installed on a front side of a vehicle for capturing real-time video of the area in front of the vehicle; a number of sensors coupled to the vehicle to detect nearby vehicles, objects and people at a predetermined distance therefrom; and a control unit for displaying clear video on a head-up display and alerting a driver of the proximal distance of the vehicle to nearby vehicles, object and person to avoid collision and accidents, the captured video being preprocessed by the control unit to display the clear image.

This device gives clear vision during foggy weather while driving a car. It shows the clear outside vision using a camera with defog setting and sensor. Help insurance companies in case of misrepresentation. Prevent theft. Provide a fast and cost-effective anti-fog anti-collision system for the vehicle to receive accidental vehicle alerts.
