Mangalore, Jun 12: Students of Electronics and Communication in the Canara Engineering College have come up with three innovative projects with the support and guidance of their professors. All three projects have immense potential for practical use.

Semi Automated Fire Extinguisher

In day to day life we encounter a lot of fire accidents leading to miserable damages. There are accidents involving high risks to human life and also there are cases where the fire extinguishing process is beyond the human reach due to congested space and complexity of the situation. Madhukar Nayak K, Prashanth Prabhu B and Ashish Raveendran Govindan have successfully built a Semi Automated Fire Extinguisher with Graphic User Interface ' to tackle such situations.

The purpose of this project was to provide an ease of operation to the firemen and eliminate the life risks associated with fire accidents. This 3.5feet in high robot is equipped with a camera to capture live video and upload it to the web server using Wi-Fi technology. The robot is also capable of detecting the spots of highest fire intensity and extinguishing fire in these places with highest priority. The robot is controlled through RF communication by an operator located at a safer distance. Since there is a live video upload on the website, any skilled person around the world can have a look at the scenario of the accident, judge the criticality of the situation and suggest suitable measures that can be taken to the operator.

The project was done under the guidance of Dr. Shantharama Rai C.,HOD ECE Dept. and Mr. Padmahasa M., Asst. Professor ECE Dept. Prof. Subramanya Bhat,Associate professor ECE Dept. was the project coordinator.

Heart Rate and ECG monitoring system

The second project, implemented by Anjali Kamath, Bamini Shenoy, Chethana Prabhu and Meghana Shenoy is a Heart Rate and ECG monitoring system '. Heart diseases continue to be the leading cause of mortality in India in an era of Industrialization, changing lifestyles and dietary habits. The mortality rate reported in government hospitals shows an increase in death due to heart diseases, and this trend is expected to continue into the next decades. Since heart disease is increasingly affecting human lifestyles, rehabilitation and practical devices are being carried out and created in order to reduce the disability from heart diseases.

The purpose of the experiments they conducted was to monitor the heart rate and ECG of a remote patient and help diagnose the problem which integrates RF technology. The results show that implementation of wireless technology in the existing ECG monitoring system eliminates the physical constraints imposed by hard wired link and allows users to

conduct own check up at anytime anywhere. Their experiment is also concerned with finding the optimum position to place the electrodes so as to have efficient results

This project was done under the guidance of Prof Jayashree K ,Assitant Professor, Department of E & C, it was also supported by Prof. Subramanya Bhat, Associate professor and Dr. Shantharama C Rai HOD E&C Department.

Buck boost converter

The third project was a simulation and implementation of buck boost converter '. This project was implemented by the students ashwini shenoy, joythi kirthi K Raman Maashree Amin under guidance of Prof Subramanya Bhat, Associate Professor.The project work was supported by Dr. Shantharama C Rai HOD E&C Department

Using buck boost converter it is possible to convert one DC voltage to other DC voltage. This converter is very useful in cases where a variable input voltage needs to be converted to a fixed output voltage. Here the output obtained from solar panel (8-20V) Is converted using the designed circuit to run the loads such as DC fan ,DC LED lights which requires constant 12v DC. This project finds its application to provide electricity in rural areas using renewable resources.

All three projects have been appreciated by Prof.T.N.Shanubhogue, principal and Management of Canara Engineering College, Mangalore.

SHRIMP.jpg

Mangaluru, Dec 7: A rare bamboo shrimp has been rediscovered on mainland India more than 70 years after it was last reported, confirming for the first time the presence of Atyopsis spinipes in the country. The find was made by researchers from the Centre for Climate Change Studies at Sathyabama Institute of Science and Technology, Chennai, during surveys in Karnataka and Odisha.

The team — shrimp expert Dr S Prakash, PhD scholar K Kunjulakshmi, and Mangaluru-based researcher Maclean Antony Santos — combined field surveys, ecological assessments and DNA analysis to identify the elusive species. Their findings, published in Zootaxa, resolve decades of taxonomic confusion stemming from a 1951 report that misidentified the species as Atyopsis moluccensis without strong evidence.

The shrimp has now been confirmed at two locations: the Mulki–Pavanje estuary near Mangaluru and the Kuakhai River in Bhubaneswar. Historical specimens from the Andaman Islands, previously labelled as A. moluccensis, were also found to be misidentified and actually belong to A. spinipes.

The rediscovery began after an aquarium hobbyist in Odisha spotted a shrimp in 2022, prompting systematic surveys across Udupi, Karwar and Mangaluru. Four female specimens were collected in Mulki and one in Odisha, all genetically matching.

Researchers warn the species may exist in very small, vulnerable populations as freshwater habitats face increasing pressure from pollution, sand mining and infrastructure development. All verified specimens have been deposited with the Zoological Survey of India for future reference.

Bengaluru: 'Nati koli saaru' (country chicken curry) considered one of Chief Minister Siddaramaiah’s favourites along with steaming hot idlis was on the breakfast menu at Deputy CM D K Shivakumar’s residence on Tuesday, according to official sources.

The spread also included 'nati koli' fry, vada and pongal, among other items, they said.

In an apparent show of unity, Siddaramaiah visited Shivakumar’s residence for breakfast, just days after the two leaders shared a meal amid a simmering power tussle in the state Congress.

Siddaramaiah drove to the Deputy CM’s residence in Sadashivanagar, where he was received by Shivakumar and his brother D K Suresh, who is a former Congress MP.

Suresh and Kunigal MLA H D Ranganath, a relative of Shivakumar, joined them for breakfast, which featured a mix of vegetarian and non-vegetarian dishes.

Speaking to reporters later, Siddaramaiah said Shivakumar had invited him during his visit to the CM’s residence for breakfast on Saturday.

Asked about the difference between the two meals, the chief minister said, "At his (Shivakumar’s) house it was non-veg, while at my house it was veg. He is a vegetarian, I am a non-vegetarian. I had not prepared non-veg. I told DK to get chicken from the village as you won’t get the original in Bengaluru."

Shivakumar said he had initially invited Siddaramaiah to his residence, but the CM had suggested visiting his place first and reciprocating later. "It was a vegetarian breakfast at the CM’s house on Saturday," he noted.

"Today, I invited him (the CM) to my house. He enjoyed the breakfast, which had his Mysuru taste," Shivakumar added. At this point, Siddaramaiah remarked that Shivakumar’s wife is also from Mysuru.

Saturday’s breakfast at Siddaramaiah’s official residence, held as part of efforts by the Congress high command to ease tensions in the leadership dispute between the two, reportedly included idlis and sambar, according to official sources.
