Smartphone’s camera, flash can measure blood oxygen up to 70% at home

Published

A team of US researchers has found that smartphones are capable of detecting blood oxygen saturation levels down to 70 per cent — the lowest value a pulse oximeters should be able to measure.

The proof-of-principle research by University of Washington (UW) and University of California San Diego researchers involved participants placing their finger over the camera and flash of a smartphone, which uses a deep-learning algorithm to decipher the blood oxygen levels.

When the team delivered a controlled mixture of nitrogen and oxygen to six subjects to artificially bring their blood oxygen levels down, the smartphone correctly predicted whether the subject had low blood oxygen levels 80 per cent of the time.

“Other smartphone apps that do this were developed by asking people to hold their breath. But people get very uncomfortable and have to breathe after a minute or so, and that’s before their blood-oxygen levels have gone down far enough to represent the full range of clinically relevant data,” said co-lead author Jason Hoffman from University of Washington.

“With our test, we’re able to gather 15 minutes of data from each subject. Our data shows that smartphones could work well right in the critical threshold range,” Hoffman said in the study published in npj Digital Medicine.

Another benefit of measuring blood oxygen levels on a smartphone is that almost everyone has one.

“This way you could have multiple measurements with your own device at either no cost or low cost,” added co-author Dr. Matthew Thompson, professor of family medicine in the UW School of Medicine.

This would be really beneficial for telemedicine appointments to be able to quickly determine whether patients need to go to the emergency department or if they can continue to rest at home and make an appointment with their primary care provider later.

To gather data to train and test the algorithm, the researchers had each participant wear a standard pulse oximeter on one finger and then place another finger on the same hand over a smartphone’s camera and flash.

The researchers used data from the participants to train a deep learning algorithm to pull out the blood oxygen levels. The remainder of the data was used to validate the method and then test it to see how well it performed on new subjects.

“The camera records how much that blood absorbs the light from the flash in each of the three colour channels it measures: red, green and blue,” said senior author Edward Wang, assistant professor at UC San Diego.

The team hopes to continue this research by testing the algorithm on more people.

Tesla To Open First Charging Station In Mumbai Next Week: All Details

Published

on

US-based electric car maker Tesla will open its first charging station in India next week in Mumbai, the company announced on Friday.

The station will have four V4 Supercharging stalls for DC charging and four destination charging stalls for AC charging.

The Superchargers will offer a peak charging speed of 250 kW, priced at Rs 24 per kWh, while the destination chargers will provide 11 kW at Rs 14 per kWh.

“This will be the first of the eight Supercharging sites that were announced during the launch in Mumbai, with more planned across the country, to provide the optimal cross-country experience,” the company added.

Tesla said this will be the first of eight Supercharging sites announced during its Mumbai launch last month, with more planned across the country to make cross-country travel convenient for Tesla owners.

The company had entered the Indian market in July with the launch of its Model Y, priced from Rs 59.89 lakh, along with its first experience centre at Maker Maxity Commercial Complex in Bandra Kurla Complex in Mumbai.

The BKC facility offers both fast-charging and regular options, catering to the needs of different EV users.

According to Tesla, the Model Y can gain up to 267 kilometres of range in just 15 minutes using its Superchargers — enough for five round trips between Mumbai’s Chhatrapati Shivaji Maharaj International Airport and the Gateway of India.

“Model Y can add up to 267 kilometres of range in just 15 minutes with Tesla Superchargers, enough for 5 return trips between Chhatrapati Shivaji Maharaj International Airport, Mumbai and Gateway of India,” the US-based carmaker said.

As part of its customer offer, Tesla will also provide a free wall connector with every new car purchase, which will be installed at the buyer’s residence.

Tesla’s First India Showroom To Open In Mumbai On July 15: All Details

Published

on

As Elon Musk-owned affordable satellite internet service Starlink gets prepared to finally launch its services in India, his other venture, electric car company Tesla, is also stepping closer to kick-off its operations in the country from this month.

Although not manufacturing in the country at the moment, the company is set to open its first showroom in Mumbai on July 15.

Called an “experience centre”, the Tesla showroom in the financial capital is situated in a 4,000 square feet retail space, which is closer to US tech giant Apple’s flagship store in the city.

This move comes as part of Tesla’s broader expansion strategy in India. In June, the company leased a commercial space in Mumbai’s Kurla West, which is expected to serve as a vehicle service facility.

Tesla now has four commercial properties in India, including an engineering hub in Pune, a registered office in Bengaluru, and a temporary office near BKC.

Tesla India Motor and Energy Private Ltd had leased a 24,500-square-foot space in Mumbai’s Kurla West to set up a service centre, located close to its upcoming showroom in BKC.

This move marks a significant step in Tesla’s plans to enter the Indian electric vehicle (EV) market, although the company does not currently intend to manufacture vehicles in the country.

According to real estate documents sourced by CRE Matrix, a property data analytics firm, Tesla signed a lease and license agreement with Bellissimo in City FC Mumbai I Private to rent the space in Lodha Logistics Park.

The agreement is for five years, with a starting monthly rent of Rs 37.53 lakh. Throughout the lease, Tesla will pay nearly Rs 25 crore in total, including a security deposit of Rs 2.25 crore, as per the documents.

Tesla has made it clear that its current interest lies only in selling its vehicles in India, not in manufacturing them at the moment.

“They are not interested in manufacturing in India,” Union Heavy Industries Minister HD Kumaraswamy said last month.

He added that Tesla is planning to open showrooms in India purely for sales.

The government has notified guidelines for its forward-looking EV scheme to enable fresh investments from global manufacturers in the electric cars segment and promote India as a global manufacturing hub for e-vehicles.

New Delhi, July 5: In just 10 years, the country have seen 88 new airports — nearly one new airport every 40 days — and added 60 additional flights every hour, Civil Aviation Minister Ram Mohan Naidu has said.

According to the minister, flying in India today is more accessible, more available and more affordable.

“Under the leadership of Prime Minister Narendra Modi, Indian skies are more connected, competitive and collaborative, said Naidu, reiterating the ministry’s commitment to collaborative, state-specific strategies for achieving inclusive aviation growth.

He was speaking at the ‘Northern Region Ministers’ Conference on Civil Aviation 2025’ in Dehradun, organised by the Ministry of Civil Aviation

“Through this strategic initiative we aim to identify the regional opportunities and unlock the vast potential of Tier 2 and 3 cities. If we look at the sector through numbers, then we can clearly see the scale of the opportunity that exists,” Naidu told the gathering.

At the event, Uttarakhand Chief Minister Pushkar Singh Dhami underlined the pivotal role of aviation in enhancing regional connectivity, enabling tourism, and supporting socio-economic development in the state.

He appreciated the phenomenal growth in the aviation sector and highlighted the prime importance of ensuring safety in the aviation operations, including helicopter operations in the hilly terrain of the state for which “the state government and the Ministry are deeply committed”.

A series of presentations was made by the Ministry on opportunities for the states in the aviation sector.

The plenary session provided an overall outlook emerging from the day-long conference, where Naidu outlined the Ministry’s strategic priorities for the region, including the development of heliport infrastructure, expansion of UDAN routes, strengthening of Flying Training Organizations and MRO hubs, and creating synergies between the Centre, states and industry stakeholders.

The Minister also reflected on key outcomes from the one-on-one meetings held between the Ministry and state delegations, and parallel sessions between state governments and aviation industry leaders, and assured all support from the Central Government in taking the aviation sector forward.
