NYU makes face shield design for healthcare workers that can be built in under a minute available to all

New York University is among the many academic, private and public institutions doing what it can to address the need for personal protective equipment (PPE) among healthcare workers across the world. The school worked quickly to develop an open-source face-shield design, and is now offering that design freely to any and all in order to help scale manufacturing to meet needs.

Face shields are a key piece of equipment for front-line healthcare workers operating in close contact with COVID-19 patients. They’re essentially plastic, transparent masks that extend fully to cover a wearer’s face. These are to be used in tandem with N95 and surgical masks, and can protect a healthcare professional from exposure to droplets containing the virus expelled by patients when they cough or sneeze.

The NYU project is one of many attempts to scale production of face masks, but many others rely on 3D printing. This has the advantage of allowing even very small commercial 3D-print operations and individuals to contribute, but 3D printing takes a lot of time — roughly 30 minutes to an hour per print. NYU’s design requires only basic materials, including two pieces of clear, flexible plastic and an elastic band, and it can be manufactured in less than a minute by essentially any production facility that includes equipment for producing flat products (whole punches, laser cutters, etc.).

This was designed in collaboration with clinicians, and over 100 of them have already been distributed to emergency rooms. NYU’s team plans to ramp production of up to 300,000 of these once they have materials in hand at the factories of production partners they’re working with, which include Daedalus Design and Production, PRG Scenic Technologies and Showman Fabricators.

Now, the team is putting the design out there for public use, including a downloadable tool kit so that other organizations can hopefully replicate what they’ve done and get more into circulation. They’re also welcoming inbound contact from manufacturers who can help scale additional production capacity.

Other initiatives are working on different aspects of the PPE shortage, including efforts to build ventilators and extend their use to as many patients as possible. It’s a great example of what’s possible when smart people and organizations collaborate and make their efforts available to the community, and there are bound to be plenty more examples like this as the COVID-19 crisis deepens.

We’ve come full rectangle: Polaroid is reborn out of The Impossible Project

More than a decade after announcing that it would keep Polaroid’s abandoned instant film alive, The Impossible Project has done the… improbable: It has officially become the brand it set out to save. And to commemorate the occasion, there’s a new camera, the Polaroid Now.

The convergence of the two brands has been in the works for years, and in fact Impossible Project products were already Polaroid-branded. But this marks a final and satisfying shift in one of the stranger relationships in startups or photography.

I first wrote about The Impossible Project in early 2009 (and apparently thought it was a good idea to Photoshop a Bionic Commando screenshot as the lead image), when the company announced its acquisition of some Polaroid instant film manufacturing assets.

Nederlanders execute plan to resurrect Polaroid film

Polaroid at the time was little more than a shell. Having declined since the ’80s and more or less shuttered in 2001, the company was relaunched as a digital brand and film sales were phased out. This was unsuccessful, and in 2008 Polaroid was filing for bankruptcy again.

This time, however, it was getting rid of its film production factories, and a handful of Dutch entrepreneurs and Polaroid experts took over the lease as The Impossible Project. But although the machinery was there, the patents and other IP for the famed Polaroid instant film were not. So they basically had to reinvent the process from scratch — and the early results were pretty rough.

But they persevered, aided by a passionate community of Polaroid owners, continuously augmented by the film-curious who want something more than a Fujifilm Instax but less than a 35mm SLR. In time the process matured and Impossible developed new films and distribution partners, growing more successful even as Polaroid continued applying its brand to random, never particularly good photography-adjacent products. They even hired Lady Gaga as “Creative Director,” but the devices she hyped at CES never really materialized.

Gaga was extremely late to the announcement, but seeing the GL30 prototype was worth it

In 2017, the student became the master as Impossible’s CEO purchased the Polaroid brand name and IP. They relaunched Impossible as “Polaroid Originals” and released the OneStep 2 camera using a new “i-Type” film process that more closely resembled old Polaroids (while avoiding the expensive cartridge battery).

Polaroid continued releasing new products in the meantime — presumably projects that were under contract or in development under the brand before its acquisition. While the quality has increased from the early days of rebranded point-and-shoots, none of the products has ever really caught on, and digital instant printing (Polaroid’s last redoubt) has been eclipsed by a wave of nostalgia for real film, Instax Mini in particular.

But at last the merger dance is complete and Polaroid, Polaroid Originals and The Impossible Project are finally one and the same. All devices and film will be released under the Polaroid name, though there may be new sub-brands like i-Type and the new Polaroid Now camera.

Speaking of which, the Now is not a complete reinvention of the camera by far — it’s a “friendlier” redesign that takes after the popular OneStep but adds improved autofocus, a flash-adjusting light sensor, better battery and a few other nips and tucks. At $100 it’s not too hard on the wallet, but remember that film is going to run you about $2 per shot. That’s how they get you.

It’s been a long, strange trip to watch, but ultimately a satisfying one: Impossible made a bet on the fundamental value of instant film photography, while a series of owners bet on the Polaroid brand name to sell anything they put it on. The riskier long-term play won out in the end (though many got rich running Polaroid into the ground over and over), and now with a little luck the brand that started it all will continue its success.

Dyson and Gtech answer UK call for ventilator design and production to support COVID-19 response

Companies around the world are shifting production lines and business models to address the needs of governments and healthcare agencies in their efforts to slow the spread of COVID-19. Two companies answering that call are Dyson and Gtech, both of which are working on ventilator hardware, leveraging their experience building vacuums and other motor-driven airflow gadgets to spin up new designs and get them validated and produced as quickly as possible.

Prisma Health develops FDA-authorized 3D-printed device that lets a single ventilator treat four patients

The impending shortage of ventilators for U.S. hospitals is likely already a crisis, but will become even more dire as the number grows of patients with COVID-19 that are suffering from severe symptoms and require hospitalization. That’s why a simple piece of hardware newly approved by the FDA for emergency use — and available free via source code and 3D printing for hospitals — might be a key ingredient in helping minimize the strain on front-line response efforts.

Flexport, Arnold Schwarzenegger and others launch a fund to get supplies to front-line responders

There’s a global shortage of available protective equipment (PPE) and medical supplies for use by front-line responders working to fight the spread of the novel coronavirus, and the Frontline Responders Fund wants to channel donations to help address that shortage. The fund, which is seeking public donations via GoFundMe, will use all proceeds to cover the costs of transportation of these crucial supplies to the hospitals, clinics and public agencies that need them most.

Flexport is facilitating the deliveries via their supply chain management platform and services, and is receiving donations via their grant-making partner Charities Add Foundation of America (CAF), which facilitates the acceptance of charitable donations for Flexport.org, Flexport’s NGO for social good projects.

Already, Flexport has been taking steps to get equipment where it’s needed most: last week, it got 60,000 surgical masks, 34,000 gloves, 2,000 surgical gowns and 50 thermometers from MedShare to San Francisco’s Department of Public Health. But the organization wants to do more, both for SF and for other cites in that are looking for ways to shore up their own supplies.

“My neighbor is on the board of supervisors and she told me the city really needed help,” Flexport CEO Ryan Petersen said via email earlier this week. “Naturally our team stepped in and applied our knowledge of supply chains and logistics plus a long standing partnership with MedShare.org to get them PPE quickly. Now we’re scaling that effort to get more supplies for SF as well as other cities and hospitals that are also in desperate need.”

The funds made available through this fundraising effort will go to securing not only PPE, but also “testing kits, thermometers, ventilators and medicines,” according to the project’s GoFundMe page, based on what medical service providers deem to be highest priority in terms of need.

Petersen says that effectively all of his time now is focused on logistics to support these ongoing efforts, and it looks like it’ll remain that way for the foreseeable future.

Other organizations, including Apple, and now SoftBank, have been donating large volumes of N95 respirators, a key piece of front-line protective equipment. Flexport’s work could facilitate continued supply, leveraging their supply chain relationships, to ensure that equipment makes its way to front-line staff as fast as it’s able to be produced.

Donations can be made directly through the fund’s GoFundMe page, and the total raised is sitting at just under $3 million as of this writing — helped in large part by sizable donations from Silicon Valley leaders including Paul Graham, Jack Dorsey and Ron Conway, as well as celebrities including Edward Norton and Arnold Schwarzenegger.

iPadOS

Apple releases iOS and iPadOS 13.4 with trackpad support

Apple has released software updates for the iPhone, the iPad, the Apple Watch, the Apple TV and the Mac. The biggest changes are on the iPad. Starting today, you can pair a mouse or trackpad with your iPad and use it to move a cursor on the display.

Apple unveiled trackpad support for iPadOS when it announced the new iPad Pro last week. While the company plans to sell a new Magic Keyboard with a built-in trackpad, you don’t need to buy a new iPad or accessory to access the feature.

When you pair a trackpad and start using it, Apple displays a rounded cursor on the screen. The cursor changes depending on what you’re hovering over. The cursor disappears and highlights the button you’re about to activate. It looks a bit like moving from one icon to another on the Apple TV.

If you’re moving a text cursor for instance, it becomes a vertical bar. If you’re resizing a text zone in a Pages document, it becomes two arrows. If you’re using a trackpad, iPadOS supports gestures that let you switch between apps, open the app switcher and activate the Dock or Control Center.

iPads become more laptop-like with the arrival of full mouse and trackpad support

In addition to trackpad support, iOS and iPadOS 13.4 add a handful of features. You can share an iCloud Drive folder with another iCloud user — it works pretty much like a shared Dropbox folder.

There are nine new Memoji stickers, such as smiling face with hearts, hands pressed together and party face. Apple has tweaked buttons to archive/delete, move, reply and compose and email in the Mail app.

Additionally, Apple added the ability to release a single app binary on all App Stores, including the iOS and Mac App Store. It means that developers can release a paid app on the Mac and the iPhone — and you only have to buy it once.

Also, macOS 10.15.4 adds Screen Time Communication Limits, a feature that already exists on iOS. It lets you set limits on Messages and FaceTime calls.

When it comes to watchOS, version 6.2 adds ECG support for users in Chile, New Zealand and Turkey. Apple now lets developers provide in-app purchases for Apple Watch apps, as well.

All updates include bug fixes and security patches. Head over to the Settings app on your devices to download and update your devices if you haven’t enabled automatic software updates.

Kinsa’s fever map could show just how crucial it is to stay home to stop COVID-19 spread

Smart thermometer maker Kinsa has been working on building accurate, predictive models of how seasonal illnesses like the flu travel in and among communities — and its fever map is finding new utility as the novel coronavirus pandemic grows globally. While Kinsa’s US Health Weather Map has no way of tracking the spread of COVID-19 specifically, as it looks only at fevers tied to geographic data, it could provide easy-to-grasp early indicators of the positive effects of social distancing and isolation measures at the community level.

FluSense system tracks sickness trends by autonomously monitoring public spaces

One of the obstacles to accurately estimating the prevalence of sickness in the general population is that most of our data comes from hospitals, not the 99.9 percent of the world that isn’t hospitals. FluSense is an autonomous, privacy-respecting system that counts the people and coughs in public spaces to keep health authorities informed.

Every year has a flu and cold season, of course, though this year’s is of course far more dire. But it’s like an ordinary flu season in that the main way anyone estimates how many people are sick is by analyzing stats from hospitals and clinics. Patients reporting “influenza-like illness” or certain symptoms get aggregated and tracked centrally. But what about the many folks who just stay home, or go to work sick?

We don’t know what we don’t know here, and that makes estimates of sickness trends — which inform things like vaccine production and hospital staffing — less reliable than they could be. Not only that, but it likely produces biases: Who is less likely to go to a hospital, and more likely to have to work sick? Folks with low incomes and no healthcare.

Researchers at the University of Massachusetts Amherst are attempting to alleviate this data problem with an automated system they call FluSense, which monitors public spaces, counting the people in them and listening for coughing. A few of these strategically placed in a city could give a great deal of valuable data and insight into flu-like illness in the general population.

Tauhidur Rahman and Forsad Al Hossain describe the system in a recent paper published in an ACM journal. FluSense basically consists of a thermal camera, a microphone, and a compact computing system loaded with a machine learning model trained to detect people and the sounds of coughing.

To be clear at the outset, this isn’t recording or recognizing individual faces; Like a camera doing face detection in order to set focus, this system only sees that a face and body exists and uses that to create a count of people in view. The number of coughs detected is compared to the number of people, and a few other metrics like sneezes and amount of speech, to produce a sort of sickness index — think of it as coughs per person per minute.

A sample setup, above, the FluSense prototype hardware, center, and sample output from the thermal camera with individuals being counted and outlined.

Sure, it’s a relatively simple measurement, but there’s nothing like this out there, even in places like clinic waiting rooms where sick people congregate; Admissions staff aren’t keeping a running tally of coughs for daily reporting. One can imagine not only characterizing the types of coughs, but visual markers like how closely packed people are, and location information like sickness indicators in one part of a city versus another.

“We believe that FluSense has the potential to expand the arsenal of health surveillance tools used to forecast seasonal flu and other viral respiratory outbreaks, such as the COVID-19 pandemic or SARS,” Rahman told TechCrunch. “By understanding the ebb and flow of the symptoms dynamics across different locations, we can have a better understanding of the severity of a novel infectious disease and that way we can enforce targeted public health intervention such as social distancing or vaccination.”

Obviously privacy is an important consideration with something like this, and Rahman explained that was partly why they decided to build their own hardware, since as some may have realized already, this is a system that’s possible (though not trivial) to integrate into existing camera systems.

“The researchers canvassed opinions from clinical care staff and the university ethical review committee to ensure the sensor platform was acceptable and well-aligned with patient protection considerations,” he said. “All persons discussed major hesitations about collection any high-resolution visual imagery in patient areas.”

Similarly, the speech classifier was built specifically to not retain any speech data beyond that someone spoke — can’t leak sensitive data if you never collect any.

The plan for now is to deploy FluSense “in several large public spaces,” one presumes on the UMass campus in order to diversify their data. “We are also looking for funding to run a large-scale multi-city trial,” Rahman said.

In time this could be integrated with other first- and second-hand metrics used in forecasting flu cases. It may not be in time to help much with controlling COVID-19, but it could very well help health authorities plan better for the next flu season, something that could potentially save lives.

Open-source project spins up 3D-printed ventilator validation prototype in just one week

In a great example of what can happen when smart, technically-oriented people come together in a time of need, an open-source hardware project started by a group including Irish entrepreneur Colin Keogh and Breeze Automation CEO and co-founder Gui Calavanti has produced a prototype ventilator using 3D-printed parts and readily available, inexpensive material. The ventilator prototype was designed and produced in just seven days, after the project spun up on Facebook and attracted participation from over 300 engineers, medical professionals and researchers.
