Frequent natural calamities like avalanches, landslides, earthquakes are always leading to the untimely collapse of flyovers, bridges, roads, and buildings. It further results in causalities. Similarly, there are numerous reasons for drowning also. The possibility of human fatalities has inspired much recent technological advancement with the B Tech in Electronics and Communication Engineering (ECE course) in the expanding field of human safety.
Electronic sensing devices advocate strongly being more effective, reliable, cheap and user-friendly and locating people buried under vast water bodies. Innumerable technologies by the students of the list of engineering colleges in Jaipur have enhanced the safety to the full range of senses. However, these include a surveillance system that never blinks and sensors that can hear a cry for help. Undermentioned are some upcoming electronic sensing techniques that locate buried and drowning people.
TPL is an extremely efficient and sensitive rescue tool that makes use of leading-edge technology. It is used for technical rescue operations using seismic technology to listen for signs of life by the students of B Tech College in Jaipur. The device detects the presence of buried victims and identifies their exact location using wireless and/or wired ultra-sensitive seismic sensors.
Students of Top Engineering Colleges in Jaipur have introduced various scientific methods to locate buried victims. One of the most important methods is to identify and locate variations in the surface like depressions or small hills. However, a new device uses a probe that is slightly thicker than a human hair. It probes the soil, detects ninhydrin-reactive-nitrogen (NRN) in its vapor phase to collect air pockets around grave soil.
At present only probing hardware is portable, but engineers of Top 10 Engineering Colleges in Jaipur are working on making the processing end portable too so that the whole system can be used in the field.
Microwave radar technology is sensitive to identify the unique characteristics for the students of Engineering Colleges in Jaipur of human breathing pattern and heartbeat from that of other living creatures. NASA has recently developed a microwave-based radar technology known as FINDER. However, it can detect a human heartbeat buried beneath 9.14m (30-feet) of crushed material or hidden behind 6.09m (20-feet) of solid concrete. Testing has proved successful in locating people buried in nine meters of mixed concrete, rebar and gravel rubble from a distance of over nine meters.
This is a secret outdoor perimeter intrusion detection sensor. Buried sensor cables generate an invisible detection with the assistance of the professionals of Best Engineering Colleges in Jaipur. It also monitors to detect and locate intrusions. Being invisible, it offers the lowest vulnerability to the defeats of any outdoor perimeter intrusion detection sensor while ensuring site aesthetics.
The system uses ported coaxial sensor cables in order to create an invisible electromagnetic detection field. Equipment within the cables makes it possible to transmit energy from the transmitting cable by the corresponding parallel receiving cable.
In conclusion, electronic devices are currently used to search for drowning people to work with microphones and cameras. These can only help locate entrapped people who are capable of making sounds or are visible beneath ruins.
In the future, scientists or experts of B Tech Colleges in Jaipur wish to complement these resources with advanced electronic-cum-chemical sensors. It can detect buried and drowning human beings to rescue them alive. For this, it makes use of drones and robots equipped with electronic-cum-gas sensors. Also, it allows difficult-to-reach or inaccessible areas also to be searched.
