Serious fun: Corona, AR and handwashing

I have been concerned with health for as long as I can remember. In 2000 I wrote a book about a medicinal mushroom. My partner and I worked on a permaculture farm in Bali a few years ago. My diet is far from ideal, and I should exercise more, and work harder to be a vegetarian. Overall, though, my health is pretty good.

So... I am also very involved with AR... And, I wanted to test an idea, using a lighthearted approach to talk about the Corona situation. At breakfast I mentioned a few ideas to my mom, and an hour later, we had the result above.

Yes, it could be edited. The sound drops out. The camerawork is amateurish. The truth is that I didn't realize I was recording.

But there is a charm to the video, and a few concepts that I do not want to analyze too much.

The software is called FaceReplaced, and it is in beta. One result of this was that, at first, it appeared upside down when we put it on Facebook... Somehow, even that seemed appropriate for these times...

SB reading Volumetric Scan by Harleigh Shaw @ Scandy

I am definitely attending the Volumetric Filmmakers NYC Meetup on December 12.

I am also hoping to meet media companies, content producers, musicians, visual artists and anyone involved with AR, VR and volumetric filmmaking.

Interview with TIVA at the Video Show

(This post was originally created for the The Video Show in Washington DC, where the interview was recorded.)

As part of the Video Show fun, this unusual ebook guide to AR was on sale!

Although, in my presentations, I mention companies, no one is paying me to have their product or service mentioned. I am thrilled to say that Novaby is helping me with Bubiko, and that I have spent a little quality time with Tranzient and Scandy (listed below), but other than that, I am just sharing info gathered online and at trade shows/events.

What you see is a test I did with Bubiko. While I was in a car, I positioned her in the road ahead. We then drove forward. It is not clear, and I will redo this test.

But what happened is that Bubiko was in front, then she appeared in the car, and then we saw her in the road behind us. She did not move with/in relationship to the car.

This was using Facebook Spark AR. Technical support: the amazing Dana.

One style of point cloud rendering.

SLIDE 16

Another way to render a point cloud. There are many ways to create point clouds and they must be interoperable.

SLIDE 17

An example of an organization that has information that would be useful for AR in Detroit. Geographic Information Services… How much of what is under the road do they have records of? This info would be necessary for many AR services,

How do they make pointclouds-or do they even do this yet?

SLIDE 19

Another presentation from Magic Leap on how the total AR Cloud might look. They use the term "Magicverse".

SLIDE 20

A representation by the OARC on what the layers of the cloud would be. My suggested terms would be REAL1 (R1), REAL2 (R2) and REAL3 (R3). R1=the physical world. R2; the layer with few changes; buildings, landmarks, geography. R3 being the part of the AR cloud that changes the most, and has the most segmentation.

This system also lends itself to further classification. R2C22 , for example, could refer to a specific block in Chicago for example, and R2C22E could be the collective "channel" for all organizations utilizing traffic emergency communications for that area.

SLIDE 21

Microsoft Azure Spatial anchor systems. 'Anchor systems' refers to geoposing. There can be an endless number of clouds. Interoperability... Machines reading the world for humans... A browser...AI assisted browsers.

STEPHEN BLACK

Graduate of the Rochester Institute of Technology, director/writer/producer for Cartoon Network, Fox, Fuji TV and CNN, Stephen Black was involved with a $3.2M gaming startup, from 2002-7. He then became a writer/artist  while waiting for mobile spatial computing(AR/VR) to mature.

That time is now.

The ARphabet Tour will make presentations in large and not-so-large cities;  a great way to develop a market for Magic Leap on the grassroots level.

The ARphabet Tour was prompted by my last minute addition to the ARIA event at MIT next month.

Also, FWIW, I have many years of experience in Singapore, and surely we could arrange  some things there, as well as other cities in Asia.


Thank you very much, Magic Leap,  for your time and consideration. OnwARd,

SB & 3D (Why I’m excited to be in Eugene Soh’s virtual gallery project)

THIS post was written before SPOKEN started. SPOKEN is a project I am doing with Eugene Soh, an experiment in which art, text, virtual reality and social media intersect. Learn about SPOKEN here.

To enter gallery.sg and experience SPOKEN, click here.

Here is the extremely short version: from 2002 until 2008 I was involved with a visionary virtual reality project that combined educational practices with gamemaking and multimedia. However, the spiritual captain of the project was part Disney, part Microsoft and part Sex Pistols. An unexpected death, treachery, incompetence, inexperience, bureaucratic boondoggles and more made my life "interesting"... I have pages of notes about the events and the spirit of the times. We were doing things like Youtube and Second Life before they started. The project was so close... and yet so far away. (Actually, now that mobile technology has settled down, I hope that the lessons and products of that experience can be revitalized. But that's yet another story.)

In 2006, as a way of showcasing our technology,  I entered a gamemaking hackathon. A theme was given on a Thursday morning and the next day at five the results were judged.The theme was something about healthy eating, I think. Working with my programmer in Hong Kong, we made a game in which the viewer learned about the calorie count of certain foods. The player competed with an AI character.  It was fun to do. However, what I remember most was a team that made an incredible flash game. I don't remember if they won or not, but I do remember two guys on that team very well. George Parel and Eugene Soh were full of energy, knowledge and bursting with creative ideas. They still are.

I've been lucky to work with George and Eugene on a few projects since then. In 2008 I finally had to put the educational gamemaking project on hold while I waited for a programmer and the mobile device situation to stabilize.I put more time into writing and art projects. George and Eugene (that dude from Singapore) however, have kept on doing remarkably creative things with IT, art, design and more.

Virtual reality may seem to be an artificial place, but the gallery Eugene has created fills me with memories and hope. I am honored and very thankful for I Ate Tiong Bahru to be on display in gallery.sg

IATB in virtual gallery Cheers, Eugene! Cheers, George!

Ebooks: Born to Click (1 of 3)

Preface This informal essay is my way of marking the end of a certain era in ebook history. It's part snapshot, part reference materials, part journal.At the end of this post are notes about me, my experiences and my books. Thanks to Doug Rolph for his insights on economics, Eric Hellman for his input and my dad for having taken care of our family by selling books. το πνεύμα του Ιανού After I finish writing eight books, I will begin marketing. Until then, I'll probably study the ebook world less and hopefully do more writing, arting and engaging with Life. When it does comes time for me to contribute to the marketing conversation, I hope I have something to say. For now, I present the following notes, quotes and thoughts as a means of punctuating a phase in the development of ebooks as I have seen and experienced it. This is an exciting time. The ebook delivery platforms are finally stable, self-publishing has proven to have great value and a number of services have recently appeared that shorten the distances between readers and authors. It seems to me that indie ebooks and ebook marketing are about to enter a new era. This blog post makes little mention of traditional publishing. This is simply because, as much as I would like to enjoy the benefits of being a Big 5/6 author, that fruit is not now within my reach. I am however, considering joining the Author's Guild. Although I've done almost no marketing, I have studied the environments in which ebooks are created, presented, bought and sold. Some observations: 1. Except for uploading, nothing about ebooks is easy. Writing is the anti-social social media, full of long, long hours of pressure-filled solitude. Assembling an error-free book is never simple. The social part, finding an audience, is an immense challenge. I respect all of the authors mentioned in this post for they have successfully met these challenges and more.
Talent is cheaper than table salt. What separates the talented individual from the successful one is a lot of hard work. Stephen King
Based on my experiences, the work breakdown of an 88,000 word novel looks something like this: 1000 words a day (88 days) or, more likely, 500 words a day (176 days). Call it 200 days to prepare something for a proofreader. Two months for corrections, art, and ebook conversion. So, a book takes about 300 working days to finalize. About... And then there are the thousands of actions needed to connect with readers... The title of Guy Kawasaki's excellent book says it all: APE, meaning Author, Publisher, Entrepreneur This document, by Mark Coker, the founder of Smashwords, is a data-based analysis of the ebook market. Highly recommended, it covers topics important for newbies and veterans. It touches upon issues like word count, pricing, marketing and more. For instance, his research shows that the average bestseller on Smashwords is 100,000 words, and the average romance is 112,195 words. (There are more links to resources at the end of this post.) Very few traditionally published authors became bestsellers; the same is true for ebook publishing. My goal is not to become a bestseller, but to connect with the largest possible community of people who enjoy the art of reading. 2. A great writer or a great marketer... ....or, the frustration of being caught between not doing enough writing and not doing enough marketing. A writer writes, a salesman sells. Self-publishing does not equal self-marketing. Spending money wisely on promotion money means income and time to write. (See the links below) Twitter, Goodreads, FB, LinkedIn and blogging? All have their advantages and disadvantages... 3. There are no independent, hugely successful ebook-only self-publishers. Note: Two days after this post went up, I became aware of this great piece by Dana Beth Weinberg on Digital Book World. Thank you Jacqueline Church! Amazon is huge, Apple is huge, Kobo and Smashwords are very big. Unless you are selling from your own website or the back of your car, you're not truly independent. OK, A bit of an attention grabber there...but the author's need for a partnership with Amazon and ebook distributors is a dependence that cannot be overlooked. These "automatic partners" will always protect their interests first. They call the shots. Amazon is a business, not an author. Amanda Hocking is a hugely successful author. At one point, the average daily sales figure of her self-published ebooks was 9000. Again: average DAILY book sales: nine thousand! Her success was based on hard work, technological first mover advantage and an indirect tie-in with Hollywood. Consider: -the successful and pioneering integration of ebook readers into tablets and mobile as well as the launch of the Kindle (2007) and the iPad(2010) -the large demographic of young women who bought readers and tablets - the fact that, having written many books, Hocking could quickly provide a new and large market with a variety of new titles - writing books about the paranormal when Hollywood is pushing the same cannot hurt. Twilight, the hugely successful series of movies about teen vampires began in 2008. Hocking's first book, My Blood Approves, began selling in 2010. E.L. James' book phenomenon began in the fan fiction chat rooms for Twilight. The characters in Fifty Shades of Grey were originally the characters from Twilight. Could Master of the Universe, as her series was originally called, have achieved its success without an existing network of thousands of Twilight fans? These two women made their mark upon society in two different ways. As shared, collective book-based experiences: WOW! However, the writing is..."not terrible" or worse
I remember SF/F authors complaining (back in 2011) that their readers hadn’t switched to e-books yet, casting jealous eyes at the outsized romance audience. But as readers did move across, we saw people like David Dalglish and BV Larson breaking out, and the rest of “genre” fiction soon followed. http://davidgaughran.wordpress.com/2013/10/22/amazon-makes-life-easier-for-authors-of-historical-literary-fiction/
There are "indie success stories" about authors who "rode into town" on the backs of traditional publishing. Funded by Big 6 money these "indies" were advertised and publicized, sent on book tours and given things like business cards. Possibly, audiobooks were made. Hundreds, if not thousands, of their books were given away, many to reviewers. As the 'first mover'possibilities of the ebook market became clear and realistic, these authors, knighted by the Big 6 and armed with credibility and connections, rode onto a battlefield with little opposition... Undoubtedly hard work was involved, but to label them as indies brings to mind the quip about George Bush: "...was born on third base and thinks he hit a triple." There certainly are "ebook only" indies connecting with many readers and enjoying sales. I just don't know of any. (FOUND SOMEONE: LINDSAY BUROKER Please tell me about others! them! Somewhat related to this, are there any "ebook only" awards? Here, authors talk about their sales experiences. 4. The ebook world evolves to reward the reader; the prepared author benefits from this. Fan fiction. Goodreads. Ebook readers on mobile phones. The mashup between big data and metadata. Entrepreneurs with vision who see ways to connect authors and readers in a new ways.

PPE: Notes on making Deaconness Face mask for Hospitals

It is now 12:39 PM April 3. I just started this post, and will be adding to it all day. Other posts about PPE can be found here.

The Deaconess mask has been approved by the CDC.

Following are notes that I have rewritten, based on Youtube comments.

In the video, it is stated that the mask could be reused so that the outside would later be used inside. NO! NEVER!

PATTERN: The pattern is here: https://www.sewitonline.com/. You cannot download it unless you give them your email address.

This is nearly the same pattern and is a simple download: https://hellosewing.com/wp-content/uploads/face-mask-pattern-v2.pdf

............

1. CUTTING: Use a tight weave cotton polyester fabric if available. To be on the safe side with shrinkage, pre-wash your fabrics at a high temperature like it will be washed by the mask owner. If A cotton poly blend is not accessible, not, use a tight cotton (such as a good quality sheet) a tea towel, a pillowcase, or linen, in that order.

2. Make sure your side A is all one fabric and your side B is the same fabric. She did not do that in the video on purpose so that we could see the seams well. The patterned side should face the patient and the solid side faces the health care provider.

5. SEWING so according to the video or follow these written instructions https://hellosewing.com/face-mask-sewing-pattern/

6. NOSE PIECE:  Note that there are many things you can use.

-Floral, Garden or jewelry wire

-Pipe cleaners, twist ties or Christmas ornament hangers.

WATCH the video to see how she attaches it.

7. Many things can be used to slip in and out of the sides as FILTERS. Vacuum cleaner bags are the very best followed by coffee filters, and other fabrics. 

8. Should you be unable to find any ELASTIC, you may use strings, shoe laces or ribbon of any kind. Thread through 36 inches of length. Tie the upper ribbon with a bow so that the user does not have to do so and leave the lower ribbon untied so they can custom fit it.

9. Try to collect fabric, elastic and nose materials from your friends and neighbors or ask them to please buy you a some cotton blend fabric. . Fabric stores allow you to order online and then do curbside pick up. 

1. PATTERN: if you cannot find the pattern, Print the nearly identical pattern from hellosewing.com/wp-content/uploads/face-mask-pattern-v2.pdf.  OR use the one given to you by your sewing group. MAKE a plastic or cardboard copy of an L, M and sized pattern based on the pattern blue, red or green. Start with L and then cut away to M and then cut away to S. This sturdier pattern will hold up better as you cut fabrics many times. 

2. Take care not to enlarge this pattern when you draw around it to make the sturdier one.

3.Label the patterns L – A and L– B etc. Side A will be the smaller one and side B will be 1 inch longer on the Right side.  This follows the video description. 

10.  Get SEWING and remember it is protection that we seek not perfection!

Let’s say we build twenty thousand ventilators in a World War II-style effort,” he said. “It could come down to, O.K., who is physically at the hospital to take delivery?” Or, “How does a doctor know that it’s O.K. to use these ventilators? Do you print a piece of paper saying ‘This has emergency F.D.A. approval’ and stamp it on each one?” He went on, “Can a doctor train up on this equipment in an hour?” And what if there are enough ventilators, but not enough doctors to operate them? What will we do then? ♦

MIT-based team works on rapid deployment of open-source, low-cost ventilator

http://news.mit.edu/2020/ventilator-covid-deployment-open-source-low-cost-0326

...............

A friend going into Crit Care recommended this after I said I’d have to manage an open ICU next yr as a hospitalist. My program only lets fellows and attendings touch the vents and doesn’t do all that much vent teaching.

I read this over three times in 2 weeks (short read) and can now explain vents to my co-residents. While you obviously still need the hands on, this book will give you all the tools you need to manage the vast majority of vent cases. It’s explained as simply as I can imagine, and really takes the mystery out of vents making you think “ Eh, vents aren’t that difficult.” Highly recommended for anyone who needs to know how to manage vents.

Here are some standard settings used with a hospital ventilator when a patient is intubated:
INITIAL SETTINGS
* Volume per Breath = no less than 6 ml/kg of predicted body weight; no more than 8 ml/kg of predicted body weight
Predicted body weight is based on a patients height.
This is the chart to calculate predicted body weight:
http://www.ardsnet.org/files/pbwtables_2005-02-02.pdf
Volume per breath must be configurable by health care provider; increments of 100 ml is probably acceptable as long as volume per breath falls within 6-8 ml/kg
* Breaths per minute = 10 - 20 breaths/ minute
The must be configurable by health care provider. Increments of 1 breath per minute is required
Note: practioner’s goal is to deliver a total volume per minute (volume per breath x breaths per minute).
If the volume per breath is on the high end, the breaths per minute can be dropped to achieve the target volume per minute objective.
In other words there is some wiggle room that’s acceptable in both these settings for a particular patient because the other setting can compensate for it.
* Minimum air pressure provided to patient at trough of breathing (exhalation): 0 - 25 cmH2O (most common setting for Covid 19 appears to be starting at 5 cm H2O working up to 15 cm h2O)
Must be medical provider configurable, ideal would be in 1 cm H20 increments, 2.5 cm H2O would be the largest acceptable increment.
(This setting keeps “lungs” from “collapsing” during exhalation)
* need an oxygen intake port that can handle 40 - 60L oxygen at 100% concentration which is usually delivered from the hospital wall.
Oxygen at the source is always 100%.
100% oxygen can be mixed with atmospheric air, which is 21% oxygen, in ratio to get desired level of oxygen that the patient needs.
Oxygen concentration that the patient receives usually starts at 100% and dropped to the lowest level possible that provides adequate oxygen in the blood and adequate carbon dioxide range in the blood. A medical provider will draw blood approximately every 30 minutes when tweaking ventilator settings to get the settings right for the patient.
Hospital ventilators have two modes:
Mode 1: Dr sets the desired volume per breath, ventilator uses as much pressure as needed to deliver the volume. (A compromised lung will require more pressure to “inflate” than a healthy one). This is known as “volume mode”
Mode 2: Dr sets target pressure for ventilator to reach, regardless of volume per breath. This is known as “pressure mode”
volume based mode is used more often than pressure based mode.
A ventilator that delivers a fixed volume of air per breath must also have a sensor to indicated how much pressure was needed to deliver the breath.
This is important as both a safety and diagnostic tool.
This peak pressure used to deliver the inhalation breath if too high for too long can damage the lungs. If pressure needed to deliver a set volume is increasing this has diagnostic relevance to the doctor and is key to monitoring the patient
In volume based mode, the pressure needed to deliver the inhalation is a reporting feature.
In pressure based mode, the pressure level is a user configurable setting.
Safe level of peak pressure is general less than 35 cm H2O.
When pressure exceeds this level, it’s a sign to the practitioner that patient has too much volume per minute; and prompts practioner to verify this by X-ray and usually to reduce volume per breath, or breaths per minute.
Finally it is useful for practioner to know how much pressure the system has when the system is on hold. A system pause button is useful to pause the ventilator and to determine the pressure at the end of exhalation coming from the patient. This is a nice to have feature. The other features are more important.

Button mask info here.

These are comments and links about materials. I am constantly organizing and editing all of these, and the organization is improving, slowly.

Every day fabrics that you likely have at home:

You can use fine men’s shirting or high thread count sheets for fabric. You can use a third layer of cotton fabric in center if you can’t access HEPA quality fabric. Also you could use a non woven interfacing for that interior layer. The idea is that the three layers of woven fabric are offset from one another causing air when it migrates in or droplets when they migrate out to not have a straight path. If you use non woven interfacing even better because it is a complex matrix. The entering particulates collide so to speak with the fibers and are captured. Also you can consider a synthetic fabric for the middle layer since many polyesters and nylon are charged and can better capture charged cells. Instead of the pony holders I’ve used fold over elastic about 28 inches long to bind each short side of the mask. This leaves stretchy tails for tying (makes it easier to fit) as you just zig zag across folded over elastic from one end to the other. Many have also used garbage bag wires and plastic floral stems for the nose piece, you can sandwich it in duct tape so it stays waterproof. I suggest inserting it into a 4” casing made with fold over elastic sewn to the lining side of the mask. This way you can reinsert new wire as needed. Lastly after you turn it consider top stitching around to increase durability. Good work guys!

In Gainsville FL, nurses have been using the surgical fabric that is used under tools in surgery. It is 99% non permeable and we have a group that is promoting use of that fabric as opposed to cotton for homemade masks. For sewing groups in our MN area we are supplying the fabric to keep our front line workers safer. Anyone can buy the fabric, resources are on the site. maskarmy4heroes.weebly.com

Commercially available medical fabrics and filters

..........

It was shared with me that the product called Halyard H600 2 ply spun polypropylene is being made into masks with the support of the University of Florida. Dr. Bruce Spears a professor for anesthesiology the U of F College of Medicine recommeded the use of this product based on the manufacturer's recommendations. He stated that the masks are 4% more effective than the N95. This information is on the University of Florida website. I am a University of Iowa RN and have a BSN. I have been sewing many years also.

A study into the effectiveness of home made face masks done by I think it was Cambridge University in the UK showed that any more than 2 layers of fabric made negligible effects on the effectiveness of the mask. On particles the size of SARS2 nCoV, no matter the number of layers, woven cotton rarely blocked more than about 50-60% of the air born particles. This style of mask only really shows it's effectiveness when everyone wears them and uses them as a method of slowing the spread rather than a method of protecting the wearer from infection. But as the aforementioned study left in it's foot notes "A mask is better than no mask".

Thank you for posting this. On a related note, existing face masks can be treated with polyethelyneamine and or catechin, an African plant, to create an effective viral blocking mask; Here are some selected citations; "Studies published by Tiliket et al. and Catel-Ferreira et al. in 2015 demonstrated a cellulose based material for airborne virus filtration in which a low-cost non-woven cellulose material (Kimwipes) were chemically modified by coating them with polyethylenimine (PEI) or grafting in an antiviral agent; catechin." "The filtration efficiency of the modified filter media was first tested on aerosolized T4D viruses (Enterobacteria phage T4, Doermann’s strain T4D). Then the treated filter was inserted inside a commercial medical mask in place of its cellulose layer and the reconstructed mask was challenged with TD4 aerosols to evaluate its virus removal efficiency." "Both treatments significantly improved the virus capture factor (ratio of upstream to downstream PFU contents) of KW cellulose wipes and of reconstructed commercial masks when compared to original masks and to masks reconstructed with untreated wipes." Tiliket, Ghania & Ladam, Guy & Nguyen, Trong & Lebrun, Laurent. (2016) published "Polyethylenimine surface layer for enhanced virus immobilization on cellulose." Search for that article online. Polyethylenimine (PEI) is a polycation, which is readily adsorbed by the cellulose matrix from a 0.1% w/v solution in NaCl 0.2 M (ca. 100 ng cm−2). Further PEI adsorption steps at higher PEI concentrations induce a linear growth of the PEI films, suggesting that free adsorption sites still exist after the initial adsorption. The adsorbed PEI chains are resistant to variations of the ionic strength up to NaCl 1 M. "Promisingly, the adsorption of T4D bacteriophages are 15-fold more efficient onto the PEI-treated fabric, compared to the native regenerated cellulose films, as measured by QCM-D. This confirms the strong affinity between the negatively charged viruses and PEI, even at low PEI concentration, probably governed by strong electrostatic attractive interactions. This result explains the remarkable improvement of the affinity of medical masks for virus droplets when one of their cellulose layers was changed by two-PEI-functionalized cellulose-based filters." Polyethylenimine is commercially available. This should be of interest to DIY mask makers.1REPLY

Olson Mask instructional videos and notes

Updated April 2, 11:32 AM EST.

www.blacksteps.tv/ppe-open-source-plans/ (ventilators, 3D printing +)

Plans for masks with buttons. (More comfortable, a bit more complicated.)

 Olson masks: easy to make and no special instruments are needed. They have a special filter pocket. This mask can be washed and reused. If the fabrics do not match it is fine. The point is to have no frayed edges or missed seams.

The pattern is here: https://northmemorial.com/wp-content/uploads/2020/03/north-memorial-health-homemade-healthcare-masks.pdf

This is the same pattern and instructions, but has more photos: https://www.regmedctr.org/webres/File/OlsonMask_wPattern_v3-USE%20THIS%20ONE.pdf

DO NOT leave your home to purchase any supplies. Please only use what you have on hand in your home.

BELOW ARE COMMENTS that are not necessary to read. The video and the instructions above are very good!

If you can find out what kind of filter insert the hospital is using, do so, and adjust accordingly.

.............

Ball point machine needles are not the best. They are designed for knits, and if used on regular fabrics, they make bigger holes and may cause the motor of the machine to overheat.

...........

Joann Fabrics is giving out kits for making masks. Once they're made, you can bring them back to Joann and they will then distribute the masks to medical centers and hospitals in need. Call your local Joann Fabrics to see if they are participating in this program.

......

Have you folks sent this to the CDC for recommendation? Your Olson design is clearly superior to the "Deaconess" one everyone else is making. I'm being a thorn in the side of the Mask Making group in my county, because they're all on board with the Deaconess, just because it went to the CDC. We've been hearing that the elastic people are using in the inferior masks is degrading during sanitation, and your design doesn't require permanent installation of elastic. I hate that people are doing a ton of work making those inferior designs and they're turning into one use disposables anyway.

........

Just a thought. I know of some nurses that have been told to reuse the N95. so they are using the handmade mask to cover a new N95 to keep the N95 clean to reduce the chances of infecting them selves when they take it off and on. Then sending the handmade down to be stabilized for the next day or shift. I hope this helps in some small way or at the least gives you another idea. God bless and stay safe.

............

Also I would like to add, on the center seam of this mask, are holes created from the stitch, you should put a separate piece of backing (attach it to the facing side) to block those holes, set that piece of fabric between the self and facing.

.........

https://www.mask-match.com/ connects makers with those who have needs.

Hint- If you are making a number of these at the same time you can save a ton of time by sewing all of one section at the same time, ie all the mouth piece seams, etc. , rather than one whole mask and then another whole mask. Also run the pieces together one after the other without cutting the threads,( just have a basket or bin ready to catch the pieces if you have enough to fall behind the sewing machine.) If you get them close enough together you can cut them apart with just one snip! Stack them up and do the next step.

...........

I have experimented with a design similar to this and decided that the seal above the cheeks was not sufficient. When leaning forward it pulls away. It can be given elastic ribs which prevent this but it adds almost 5 minutes to the manufacturing of each mask which is already high considering the complexity of the mask shape. I have found that a much better mask to make is a standard, pleated surgical mask with one long stainless steel ridge along the top. I was testing one of said masks out at the supermarket 2 days ago and was pleasantly surprised when taking it off only to smell a strong smell of perfume from the person next to me. A smell that the mask had been preventing me from smelling. In addition to the fact that they make for a better seal, they are also much quicker and simpler to manufacture. I have just finished making 50 today to donate to my local doctors surgery who is still waiting on their PPE care package from the NHS over here in the UK. An additional piece of information that you may find useful in shrinking production time.

.......

Just made my first one. If making for general use, 6" of elastic at each side works for average female. Side edges of mask were turned under 1" to make the elastic casing. Used 5" of craft wire with ends bent in, then inserted in mask, centered and sewed around wire by make a running stitch below and at sides. Any breathable additional inside layer would most likely help to some degree -may try interfacing even. Please realize these are not intended for medical use unless modified by health experts, ie the tape, etc.

.........

Tips from someone who sews regularly: 1.) Fold your material for double layer and you only need 1 of each piece because it makes a mirror image for 2nd piece. For lots of masks, glue stick the pattern to a piece of cardboard to trace around your fabrics. 2.) If you want a moldable nose piece, you can use gardening tie wire doubled up to about 2 1/2 to 3 inch length. You can tack it in place by hand or enclose it in a separate strip of fabric and as you sew your edge it catches your strip. If you expect to wash it over and over again, I would enclose it. For me I used the tack method for masks that were already made and for new masks I enclose them in fabric that kinda looks like the paper over a straw but smaller. Or, you could tack it and hide under your top stitch hem. 3.) If you happen to have an overlock machine/serger you can save time and get a better product by overlocking all of your major seams which will prevent any fraying and sew the seams at the same time. Then use a regular machine for the final top stitching if you choose to top stitch. If you don't have an overlock machine, I would fold the edges of the mouth piece edges twice, iron and then top stitch. This way your fabric won't fray. 4.) I happened to have a roll of elastic that was much thicker than I needed. I simply trimmed it down to thinner pieces. 5.) You do not need to leave a section open to turn inside out. Your mouth piece opening can be used to turn right side out.

i‘m sewing very similar masks, but only out of 3 pieces. it‘s actually not necessary to sew 2 pieces completely together to get a mask with a good shape that lies flat around nose and chin. sewing out 2 triangles („abnäher“ in german) does the trick. this actually makes the process even faster

.............

So... I experimented with a few different materials for the nose piece and the BEST one so far is PAPER CLIPS! even better is you use the ones that are already covered with plastic so they will not get as damaged by water when washing. I cut one paper clip in half with pliers, then interweave it into a piece of fabric, then I use double sided fabric adhesive to attach it to the bridge of the nose on the "wrong side" of the filter holder (the mouth piece of the pattern). For the elastic I was thinking a few things would work if you wanted something that goes behind your head instead of over the ears- those replaceable bra straps work pretty well, but elastic or just ribbon with a cord lock is great. You can get cord locks from Amazon for like 6 or 7 dollars.

Dear friends, doctors, and colleagues, CustomSurgical has decided to focus all our attention on the current COVID-19 crisis. Therefore, we are open to help prototype and print all the ideas from anyone involved in the healthcare domain that would help this crisis. The first solution in our MedSHIELD-19 project started with Dr. David Kohn and Dr. Cristian Muniz, who designed a 3D connector to attach to a snorkeling mask together with an HME filter. This mask set can be used for virus protection at a time when there is a lack of medical masks and any options are much needed! ⚠️⚠️⚠️You can download the 3D model FOR FREE at https://lnkd.in/gEpp6F2 If you don't have a 3D printer or another type of mask, send us a message through the webpage form and let us know about the specifics so we can help customize a solution. Custom Surgical engineers are open to receiving your calls and emails at info@customsurgical.de, and to help design and print your requests for FREE. We want to help during this world crisis and therefore we will be working from home to support you in any way needed.

Sincerely,

Federico AcostaCEO at Custom Surgical UG

-Seems like very interesting low tech enhancement of simple masks or DIY fabric masks. One issue - they stated that "The stability of salt coating on PP fibers was tested under harsh environmental conditions. Incubation at 37 °C and 70% relative humidity (RH) for 1 day did not cause any significant difference in filtration efficiency" - but what about breathing ? It raise the RH inside the mask and by this dissolve the salt crystals. Maybe this process still can be applied to masks with breath-out valves to get the desired effect.

  • The key component is polysorbate20. Without that, all you have is a salted mask with fibres that have been compromised by water.
  • Ingredients
  • DI water
  • 99.99% NaCl (good quality pool salt
  • Polysorbate20 (tween20)

 Ratios
To 100ml DI add
29gm NaCl
1.5ml polysorbate

Method
Heat water to below boiling
Gradually add salt, agitating to max suspension
Cool
Add polysorbate20
Shake
And thats it

Increase in filtration efficiency between 40-70%

Filtration efficiency increase 40-70%
Eg 3M F1 is 80% of 0.3 micron
Increase to between 88-94%

Mechanical: polysorbate alters mask fibre from Hydrophobic to hydrophillic, meaning static charge is redundant requirement, now reliant on impact of droplet to filter
Droplet now wicks along fibre, NaCl makes direct physical contact with pathogen
Viral HA inactived within 5 minutes
Effect occurs via recrystalisation of salt

We have made almost a thousand of these so far for multiple hospitals, animal shelters and dentist offices. They have been approved by the hospitals and don't have an open top. They use a simple 3 hole punch and a rubber band or zip tie to adjust the sizing. Around 11g of filament.

  •  I now have what I mentioned on thingverse.. I also got approval today direct from a hospital trial.. they asked for a TON more. If you want the 2 piece design, please print one and test before printing a ton. I put in a V4 file for a secondary option. I'm a design engineer. If V3 doesn't work for you, and V4 male end doesnt work for you.. let me know and I will custom make one for your printer. I am making 9 every 5 hours on my markforged printers. https://www.thingiverse.com/thing:4249139
  • Post prototypes here to get clinical testing: https://3dprint.nih.gov/collections/covid-19-response
  •  I modified the file to be printed in 22 minutes with provided settings on stock Ender3 https://www.thingiverse.com/thing:4253431

If you have a 3d printer and want to help with the Coronavirus Outbreak, now is the time to shine.

I am working in the Houston area with TX/RX Labs and with the University of Houston to help mass produce face shields. There are 2 parts to the face shield, 1 3d printed upper part and 1 laser cut polycarbonate shield. We're also looking to start sewing face masks within the week. If you can help, and are still in Houston, please fill out https://forms.gle/kU559a2kn1zT7jtm7
If you need masks and you are a hospital, contact bsli@uh.edu and I'll forward it to the right people.

If you can, donate. https://www.gofundme.com/f/txrx-manufactures-protective-med…
