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.

The prototype will now enter into a validation process by the Irish Health Services Executive (HSE), the country’s health regulatory body. This will technically only validate it for use in Ireland, which ironically looks relatively well-stocked for ventilator hardware, but it will be a key stamp of approval that could pave the way for its deployment across countries where there are shortages, including low-income nations.

Ventilator hardware in the U.S. is also likely to encounter shortages, depending on the progress of coronavirus spread in the country. On Wednesday, the White House enacted the Defense Production Act, which provides broad powers to the President for redirecting materials and private company production capacity to building much-needed supplies and equipment in a time of crisis.

During Wednesday’s White House briefing on the current COVID-19 situation, U.S. VP Mike Pence said that there are only 10,000 ventilators in the country’s strategic reserve, which, while it doesn’t take into account the stock of equipment in hospitals or healthcare facilities around the country, likely won’t address the overall needs of medical professionals in case some of the more serious projections about the infection come true.

The project could be one way to help address the shortfall, along with commitments by automakers including GM, Ford and Tesla to produce ventilator equipment should the need arise.

The group behind the ventilator also recently changed the focus of their Facebook community, renaming the group from the Open Source Ventilator Project to the Open Source COVID19 Medical Supplies community. They’re looking at expanding their focus to finding ways to cheaply and effectively build and validate other needed equipment, including protective gear like masks, sanitizer and protective face guards for front-line healthcare workers.

Android app reviews may slow to over a week due to COVID-19 impacts, Google warns developers

Google this week warned Android developers that Play Store app review times will be much longer than normal due to the impacts of the COVID-19 crisis. Developers should expect app reviews to take up to a week or even longer, the company informed its community by way of an alert on the Google Play Console.

This slowdown in moderation efforts isn’t something that’s just impacting Google Play.

Yesterday, YouTube announced it would more heavily rely on its automated systems during this time, which meant more videos will likely be taken down by machine learning-powered systems before they received a review from a human moderator.

In both cases, the slowdowns are related to the reduced in-office staffing levels — a result of the COVID-19 pandemic, which is impacting employee scheduling at Google and elsewhere.

Up until now, Google Play had a fairly quick app review process.

For years, the company differentiated its Play Store from Apple’s App Store by allowing developers to publish without a lengthy review. This, of course, led to issues as the store was over-filled with low-quality and sometimes even malicious apps. In 2015, Google revealed it had begun to utilize an internal team of reviewers to analyze apps for policy violations prior to publication.

Despite the change in process, apps were being approved within hours instead of days, Google said at the time.

That changed last year, however, as the company implemented a more stringent review. It then began to advise developers to plan for review times of at least three days between submission and the app going live. But the length was reduced for established, trusted developers who continued to see faster reviews, Google had noted.

Review times of a week or even longer are unprecedented, much like the COVID-19 crisis itself.

News of the increased app reviews was first reported by Android Police.

A Google spokesperson confirmed the delay to TechCrunch, saying: “Due to adjusted work schedules at this time, we are currently experiencing longer than usual review times. While the situation is currently evolving, app review times may fluctuate, and may take 7 days or longer.”

The delay is also confirmed in the Play Console’s Help documentation.

Oura raises $28 million for its health and sleep tracking ring

Smart rings are still a relatively young category in the wearable hardware world, but the Oura Ring seems to be a standout in terms of early success. The Oura Ring hardware is sleek and packed with sensors, allowing it to measure a user’s sleep patterns, take your body temperature and track activity, and now Oura has raised $28 million in Series B funding to bring on new key hires and product updates.

In a Medium post announcing the raise, Oura CEO Harpreet Singh Rai revealed that to date, the company has sold over 150,000 of its rings since launch (which was in early 2018) and that its team has grown to over 100 people globally. The Series B funding comes from Forerunner Ventures, which has a strong track record when it comes to direct-to-consumer product company investments, as well as from Gradient Ventures and Square.

Along with the investment, Oura gains two new board members, and one new board observer all with expertise in different aspects of the startup’s business: Forerunner’s Eurie Kim and Square’s hardware lead Jesse Dorogusker are the new board members, and Gradient partner (and former VP of engineering at Google) Anna Patterson joins as the observer.

Oura will be revamping its website and adding a new web-based portal for Oura Ring users that offers “actionable insights,” the company says, and it’s going to be doing more in terms of collaborating with academic researchers on ensuring its products measurements and guidance remain as accurate and useful as possible.

Oura prioritizes the role of sleep in terms of its contribution to health, and has also recently ventured into the realm of meditation, but it acts as a general fitness tracking device as well. It has attracted a number of fans among the plugged-in tech elite, too, including Twitter and Square CEO Jack Dorsey. The company deserves kudos for delivering a solid, attractive and feature-rich gadget in a category that seemed like a tough sell in the early offing, and this new funding is a good vote of confidence.

Immutouch wristband buzzes to stop you touching your face

In the age of coronavirus, we all have to resist the urge to touch our faces. It’s how the virus can travel from doorknobs or other objects to your mucus membranes and get you sick. Luckily, a startup called Slightly Robot had already developed a wristband to stop another type of harmful touching — trichotillomania, a disorder that compels people to pull out their hair.

So over the last week, Slightly Robot redesigned their wearable as the Immutouch, a wristband that vibrates if you touch your face. Its accelerometer senses your hand movement 10 times per second. Based on calibrations the Immutouch takes when you set it up, it then buzzes when you touch or come close to touching your eyes, nose, or mouth. A companion app helps you track your progress as you try to keep your dirty mitts down.

The goal is to develop a Pavlovian response whereby when you get the urge to touch your face, you don’t in order to avoid the buzzing sensation. Your brain internalizes the negative feedback of the vibration, training you with aversive conditioning to ignore the desire to scratch yourself.

“A problem the size of COVID-19 requires everyone to do their part, large or small,” says Slightly Robot co-founder Matthew Toles. “The three of us happened to be uniquely well equipped to tackle this one task and felt it was our duty to at least try.”

The Immutouch wristbands go on sale today for $50 each and they’re ready for immediate shipping. You can wear it on your dominant hand that you’re more likely to touch your face with, or get one for each arm to maximize the deterrent.

We’re not looking to make money on this. We are selling each unit nearly at cost, accounting for cost of materials, fabrication, assembly, and handling” co-founder Justin Ith insists. Unlike a venture-backed startup beholden to generating returns for investors, Slightly Robot was funded through a small grant from the University of Washington in 2016 and bootstrapped since.

We built Immutouch because we knew we could do it quickly, therefore we had the obligation to. We all live in Seattle and we see our communities reacting to this outbreak with deep concern and fear” Slightly Robot co-founder Justin Ith tells me. “My father has an autoimmune disease that requires him to take immunosuppressant medication. Being in his late 60’s with a compromised immune system, I’m trying my best to keep the communities around him and my family clean and safe.”

How to calibrate the Immutouch wristband

Based on a study using wearable warning devices to deter sufferers of trichotillomania from ripping out their hair, Immutouch could potentially be effective. University Of Michigan researchers found the vibrations reduced long and short-term hair pulling. Ith admits you have to actually heed the warnings and not itch to instill the right habit, and it doesn’t work while you’re lying down. The Immutouch stops short of electrically shocking you like the older gadget called Pavlok that’s designed to help people quit smoking or opening Facebook.

Perhaps smartwatch makers like Apple could develop cheap or free apps to let users train themselves using hardware they already own. But until then, Ith hopes that Immutouch can gain some initial traction so “we can order larger quantities, reduce the price, and make it more accessible.”

Modern technologies like Twitter for rapidly sharing information could encourage people to take the right cautionary measures like 20-second handwashing to slow the spread of coronavirus. But having phones we constantly touch — before, during, and after we use the restroom — and then press against our faces could create a vector for infection absent from pandemics of past centuries. That’s why everyone needs to do their part to smooth out the spike of sickness so our health systems aren’t overrun.

Ith concludes, “Outbreaks like this remind us how we each individually affect the broader community and have a responsibility to not be carriers.” 

Tempo reveals $17M-funded $2000 weight lift training screen

Tempo wants to be the Peloton of barbells. It’s a 42-inch tall screen with 3D machine vision that tracks and teaches you as you workout. The giant upright HD display makes it feel like your personal trainer is right there with you while you compete with others in live and on-demand classes.

Tempo’s Microsoft Kinect-esque motion sensors scan you 30 times per second and notify you if your form is wrong. It’s all housed in a sleekly designed free-standing cabinet that neatly stores the included barbells, dumbbells, attachable weights, workout mat, recovery foam roller, and heartrate monitor.

Tempo opens for pre-orders today for $1995, requiring a $250 deposit and $39 monthly content subscription before shipping this summer.

Every single product in the market took a piece of equipment out of a gym and slapped a screen on it” says Tempo CEO and co-founder Moawia Eldeeb. “You need to be able to see a user to actually be able to give them guidance so they can work out safely. We wanted to build a fitness experience from the ground up with training and form feedback at the core of it.”

I demo’d Tempo this week and found the in-home convenience, motivational on-screen personal trainers, and the real-time posture corrections gave me the confidence to lift weights without the fear of injury. It might not feel quite as fun and addictive as Peloton, but it offers a facsimile of personal training that’s more affordable than in-person classes that cost $100 or more.

The idea of democratizing access to trainers is what convinced Eldeeb and the Tempo team to stretch its initial $1.8 million in seed funding for four years. While collecting data from its SmartSpot in-gym weight lifting assessment device, Tempo survived long enough to build this prototype.

“Most investors had given up on us. We built this product and had just $700,000 left” Eldeeb recalls. But once people could try Tempo, “we pitched 10 investors and got 9 term sheets. It got very competitive.” The startup recently walked away with a $17.5 million Series A round from Founders Fund, DCM, and Khosla Ventures. Now Tempo will pour that cash into marketing, retail distribution, R&D, and content production.

A founder’s journey out of homelessness

Tempo’s mission is to change people’s lives for the better like personal training did for Eldeeb. “Training is what took me out of a homeless shelter and got me to where I am I today” he reflects.

Tempo co-founder, CEO, and CPO Moawia Eldeeb

Eldeeb’s family immigrated to the US from Egypt when he was nine. But after an explosion leveled their building, they wound up in a homeless shelter. Eldeeb eventually dropped out of middle school to work in a pizza parlor and help pay the bills. But personal trainers at a local YMCA took him under their wing. He eventually paid his way through a computer science degree at Columbia University by working as a personal trainer to his eventual co-founder and CTO Josh Augustin. “Having trainers say you’re getting stronger taught me I could do something for myself.”

While at school, Eldeeb was developing an idea for a physical therapy wearable while Augustin was building 3D sensors for guiding robot perception. They soon realized that a combination of these ideas “offered us the possibility to deliver on the promise of guiding your form and tracking your progress accurately.”

In 2015, they started a company called Pivot to build SmartSpot — a similar looking upright screen that was designed for gyms. It could track users, but only output raw data about their form, like how bent a user’s knees were during a squat. It then worked with trainers to annotate the data to determine what movement patterns were safe and which were dangerous.

Gym owners bought in because it let them track which trainers were actually helping customers improve. “It held trainers accountable. If you weren’t delivering results, it’d be obvious” Eldeeb tells me. The company built up a dataset of over from over 1 million 3D tagged workouts, from hundreds of gyms, overseen by thousands of trainers. That formed the basis of the artificial intelligence that would let Pivot pivot into Tempo.

Pumping Iron With Tempo

At first, Tempo’s giant screen and black or white armoire can feel a bit daunting. The thing is about six feet tall, though it only takes up as much room as a large chair. It makes efficient use of space, with the barbell and dumbbells racked on the back, an internal shelf for the foam roller and mat, and a soft-closing cabinet on the front with the rubber-coated weight set. Keeping everything together means you won’t have to go digging in your closet to start a work out.

Tempo walks users through an initial computer-vision fitness assessment to understand your strength and flexibility so it can set base levels for its exercises. If you have an injury it needs to nurse, Tempo connects you to a human personal trainer that helps customize your workout plan. Otherwise, it uses your goals and data to set out a progressive regimen that gets a little tougher each day. It even blocks you from jumping into later classes so you don’t strain yourself.

Your workout plan begins with tutorial sessions that teach you to do the exercises with safe and proper form. When I was hunching forward during my squats, Tempo’s computer vision would ding me with instant feedback to keep my knees back and chest up. Then once I’d corrected the issue, it congratulated me with little green checkmarks. “Any product that doesn’t offer that is no better than a DVD or YouTube videos” Eldeeb remarks.

From there I could choose between a variety of class styles and lengths, ranging from high intensity interval training circuits to isolated sessions focused on particular muscle groups. In each, you watch a near life-size personal trainer doing the routines right in front of you while they demonstrate form and drop inspirational quotes.

Tempo is producing seven live classes per day from its San Francisco studio which you can also watch on-demand. You can compete against friends or strangers, and Tempo compares you rep for rep so it’s more about perfect form than reckless speed or weight. The live trainers can actually see all your data and your mistakes on a dashboard as they lead classes, and can call you out for screwing up (though you can deactivate this shame mode). Eldeeb says “knowing the trainer can possibly see your numbers will motivate you to actually do this right.”

The class selection interface is suspiciously similar to Peloton’s, though that at least will make it familiar for some. Over time, you build up an immense collection of data on your performance in each work out, excercise, and muscle. Unlike hitting the gym by yourself, you’ll never struggle to remember how much weight to use or whether you’re improving. Classes are soundtracked with dancey remixes sourced from a partnership with Feed.fm to avoid the royalty issues with original songs that slapped Peloton.

Tempo gives feedback when you’re doing exercises wrong, and when you correct yourself

For a 14-person startup, Tempo is trying to do a ton and that can leave some rough edges. The bluetooth armband heartrate monitor can have connectivity issues and the computer vision doesn’t always register every rep, especially if your posture is off. Classes also fail to include enough stretching to prevent strains, instead devoting the start of classes to warmups that ease you in but might not protect your muscles well enough. My quads were destroyed after my demo.

Tempo still achieves its primary objective: it makes weight lifting accessible. No need to drag yourself to the gym or be beholden to a trainer’s schedule, where I’d always end up arriving late and wasting 25% of my session. The form feedback fixes my core complaint about remote personal training app Future I’ve been using for nine months, which can’t see you. That’s led to minor injuries from bad sit-up posture and other incorrect movements. Tempo can’t catch everything, but it can nip some of the most common mistakes in the bud.

Eldeeb was blunt when asked why Tempo is better than well-funded competitors like $3000 Tonal’s wall-mounted resistance cable-based training system or the $1500 Mirror’s massive screen.

“The biggest problem with Tonal is two-fold. Cables and motors do not last. I want this product to be in your house for 10-plus years. [Tempo] is in gyms running 24/7 in for 3 years and it’s still working. The second biggest thing is just feedback.” While Tonal does include a camera and microphone it might employ in the future, it’s not scanning you to detect when you’re lifting weights crooked like Tempo.

As for Mirror, “What is the difference between ClassPass Live and Mirror? It doesn’t come with any equipment, and there’s no training. It’s just a two-way mirror and a Samsung LED panel behind it with an arduino board” Eldeeb rails. He claims it can’t actually monitor your workouts and that his team’s tests found Mirror would say they’d burned 500 calories when they were literally just sitting on their couch in front of it.

Eldeeb demos Tempo

If the software proves to have high retention so people actually recommend Tempo to friends, the biggest hurdle will be its price. You can buy a couple dumbbells for $50 or get a barbell weight bench for a few hundred. Even if Tempo’s $55 per month financing option plus $39 subscription makes it cheaper than a single personal training session or on-par with a gym membership, it could still seem like a serious commitment.

That feeling is magnified by how all of its equipment and classes and data can feel a bit overwhelming. The startup might have to spend a fortune on retail establishments that can guide users through their first Tempo experience. There’s also no mobile version yet, so you can’t bring the work outs on the road with you.

Eldeeb seems guinely motivated to keep improving the product so it’s better than commuting to work out. “Getting to the gym or class is often half the battle. By bringing the gym to you and structuring the classes to be as efficient as possible, Tempo not only makes improving your health more convenient, but it gives you back your most precious resource: time.”

For those comfortable lifting the cheap weights they have at home or hitting up a budget gym, Tempo might seem needlessly overwrought and expensive. But for anyone who needs more instruction or wants to get a Barry’s Bootcamp-worthy workout at home, Tempo might be just their speed.
