The Ultimate Gift: Saving Mom's Life

Original image

There is a select group of people who have achieved lifetime Mother's Day credits by saving Mom's life. However, being the kind of people they are, they will probably honor her on Sunday anyway. We hope your mother is never in the position the moms in these stories found themselves in. I'm sure your mother will appreciate flowers and a card.

First Aid

Ten-year-old John Kearney of Cumberland, Maine was hiking with his parents when his mother, April Kearney, fell 30 feet down a hill and struck her head on a rock. She suffered a seizure and was bleeding from a gash on her head. After wrapping her wound, John's father ran over two miles to get help. Meanwhile, John put his Boy Scout skills to work, keeping pressure on the wound and preventing his mother from losing consciousness. Two hours went by before help arrived, and John was still working to help April. She was airlifted from the mountain and recovered. For his life-saving work, John was honored with the the Meritorious Action Medal from the Boy Scouts, presented to him by the governor of Maine. See a video of the award presentation.

Ten-year-old Madisyn Seyferth of Sheboygan, Wisconsin, was a big fan of Grey's Anatomy. That came in handy last year when her mother Kandace had an unusually severe asthma attack. Madisyn directed a friend to start chest compression while she performed mouth-to-mouth breathing, which she learned from the TV show. Paramedic were there within minutes, and said that the CPR probably saved Kandace's life.

Eleven-year-old Keith Corbett of Orangeville, Ontario was the only family member around when his mother Genene began to choke on a piece of chocolate. Keith saw that she couldn't speak and asked her for a thumbs up if she needed the Heimlich maneuver. She gave a thumbs up and her son gave her only two thrusts before the chocolate was dislodged. Genene and her husband Dale are both advance care paramedics, and had trained both their sons in the Heimlich maneuver and other life-saving techniques -which paid off big time. Keith is now considering becoming a paramedic when he's older. Photograph by Chris Halliday.

And there are many, many stories of young children who saved their mothers' lives by calling 911. They are all heroes.

Fire

Gina VanDeWalle of Davenport, Iowa, was severely burned by an exploding firepot last year. The flaming fuel gel from the firepot stuck to her body, but her 16-year-old son, Randy Cook-McPhee, quickly took his shirt off and smothered the flames. VanDeWalle suffered burns over 20% of her body and required surgery and an extended hospital stay. Cook-McPhee took care of his younger siblings while his mom recovered.

Defense

Paul R. Newman rented a room from a woman in Bellingham, Washington. He came home drunk one day last year and began to choke his landlady. The homeowner's 11-year-old son Kobe Sturgeon went to his mom's defense. He grabbed a wooden board and hit Newman, then shot him in the face with a BB gun. Police arrested Newman, who suffered non-life-threatening injuries, for assault.

The end of the story was much sadder for 19-year-old Derwin "DJ" Watts of Chesapeake, Virginia. Charles Collins, Tanisha Watts' ex-boyfriend, had sneaked into her apartment and was waiting when she arrived home with her current boyfriend Michael Temple last month. Collins shot Temple and then held Watts and her son DJ and DJ's girlfriend in the home. The police and the SWAT team surrounded the home while Tanisha Watts tried to calm Collins down. As the standoff continued, DJ Watts made a sudden jump toward Collins and shoved his mother to the door -but was shot by Collins. The SWAT team jumped in and shot Collins, who survived. Both DJ and Michael Temple died. DJ was a senior at I.C. Norcom High and was set to graduate this month.

Kidney Donation

Katie McKissick's mother needed a transplant when her kidneys failed in 2003, and no one in the family was both a match and healthy enough to donate. Katie wanted to be tested, but doctors said no because she was under 21. Her mother waited for a kidney for a year, and when Katie's birthday approached, she was found to be a match. The transplant took place in 2004, only a month after Katie turned 21. Her mother recovered, welcomed two new grandchildren just days after the surgery, and went back to teaching.

Kristi Nelson, a news anchor at NBC-5 in Dallas-Ft. Worth, Texas, donated a kidney to her mother Helen at Baylor University Medical Center. The TV station live-tweeted the surgery last August.

Erica Liepmann, an editor at the Huffington Post, donated a kidney to her mother Terry in 2007. Twenty-two potential donors were tested, and Erica was the only viable match that was healthy enough to donate, which was surprising, considering that Erica was adopted. Erica's college classes were put on hold when her mother's condition deteriorated, but the transplant worked and gave her a new life.

Aakash Belkhade of Mumbai, India is serving a life term in prison for murder, but was granted bail to donate one of his kidneys to his ailing mother in 2010. Since then, his remaining kidney has begun to fail. He is in the process of seeking a temporary parole to get the medical care he needs, but the courts are arguing that medical care in prison is sufficient.

Dr. Asim Syed is a transplant surgeon at Hammersmith Hospital in London, England. He never knew how his work would come home until his mother Dilshad suffered kidney failure. She endured five years of dialysis in Doncaster, South Yorkshire, but last year needed an immediate transplant. Dr. Syed was not a good match, but arranged a chain of donations, in which he donated to a patient with a good match, whose relatives in turn donated to others they matched, until a willing donor in the chain was matched with Dilshad. A total of three transplants were performed on July 31st of 2011 through such an arrangement.

Daniel Autumn is a student at Heriot-Watt University in Edinburgh, Scotland. His mother, Carolyne Douglas, is suffering from kidney failure. Autumn is the best donor match for his mother, and plans to donate so Douglas can stop dialysis, which is taking so much of her time that she had to quit her job. However, Autumn was depending on working this summer to pay his tuition bill, and now won't be able to, as donating a kidney requires weeks of recuperation.

Liver Transplant

Chen Xuemei of Guangzhou, China, suffered from hepatitis and needed an immediate liver transplant last fall. Her husband Peng Hui contacted their son, 22-year-old Peng Si, who was studying at the University of Colorado. Peng Si immediately agreed to donate part of his liver to his mother, but she refused, saying her son needs to continue his education. Peng Si flew to China, but Chen still said no to the transplant plan. But then she fell into a coma, and Pen Hui signed the transplant agreement for his wife. The surgery saved Chen's life.

Anthony Figueroa was 29 years old when he died on Christmas Eve of 2010. He was thrown down a flight of stairs during a fight. His mother, Laure Hom of Staten Island, New York, had been waiting for a liver transplant for a year by then. Figueroa's liver was transplanted into Hom, who said, "I've got a piece of him still."

Kathy Goodnough contracted hepatitis C in the 1980s while working as a nurse. By 2005, her liver was failing. Her daughter Meaghan volunteered to donate part of her liver to her mother, and was found to be a match. In 2006, the transplant took place. Both women were left with partial livers, and it took six months for the organs to grow to full-size, functioning livers. It wasn't the first selfless effort on Meaghan's part, as she and her family have been hosting an annual blood drive for the Red Cross for fourteen years.

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning

Jacques Mattheij made a small, but awesome, mistake. He went on eBay one evening and bid on a bunch of bulk LEGO brick auctions, then went to sleep. Upon waking, he discovered that he was the high bidder on many, and was now the proud owner of two tons of LEGO bricks. (This is about 4400 pounds.) He wrote, "[L]esson 1: if you win almost all bids you are bidding too high."

Mattheij had noticed that bulk, unsorted bricks sell for something like €10/kilogram, whereas sets are roughly €40/kg and rare parts go for up to €100/kg. Much of the value of the bricks is in their sorting. If he could reduce the entropy of these bins of unsorted bricks, he could make a tidy profit. While many people do this work by hand, the problem is enormous—just the kind of challenge for a computer. Mattheij writes:

There are 38000+ shapes and there are 100+ possible shades of color (you can roughly tell how old someone is by asking them what lego colors they remember from their youth).

In the following months, Mattheij built a proof-of-concept sorting system using, of course, LEGO. He broke the problem down into a series of sub-problems (including "feeding LEGO reliably from a hopper is surprisingly hard," one of those facts of nature that will stymie even the best system design). After tinkering with the prototype at length, he expanded the system to a surprisingly complex system of conveyer belts (powered by a home treadmill), various pieces of cabinetry, and "copious quantities of crazy glue."

Here's a video showing the current system running at low speed:

The key part of the system was running the bricks past a camera paired with a computer running a neural net-based image classifier. That allows the computer (when sufficiently trained on brick images) to recognize bricks and thus categorize them by color, shape, or other parameters. Remember that as bricks pass by, they can be in any orientation, can be dirty, can even be stuck to other pieces. So having a flexible software system is key to recognizing—in a fraction of a second—what a given brick is, in order to sort it out. When a match is found, a jet of compressed air pops the piece off the conveyer belt and into a waiting bin.

After much experimentation, Mattheij rewrote the software (several times in fact) to accomplish a variety of basic tasks. At its core, the system takes images from a webcam and feeds them to a neural network to do the classification. Of course, the neural net needs to be "trained" by showing it lots of images, and telling it what those images represent. Mattheij's breakthrough was allowing the machine to effectively train itself, with guidance: Running pieces through allows the system to take its own photos, make a guess, and build on that guess. As long as Mattheij corrects the incorrect guesses, he ends up with a decent (and self-reinforcing) corpus of training data. As the machine continues running, it can rack up more training, allowing it to recognize a broad variety of pieces on the fly.

Here's another video, focusing on how the pieces move on conveyer belts (running at slow speed so puny humans can follow). You can also see the air jets in action:

In an email interview, Mattheij told Mental Floss that the system currently sorts LEGO bricks into more than 50 categories. It can also be run in a color-sorting mode to bin the parts across 12 color groups. (Thus at present you'd likely do a two-pass sort on the bricks: once for shape, then a separate pass for color.) He continues to refine the system, with a focus on making its recognition abilities faster. At some point down the line, he plans to make the software portion open source. You're on your own as far as building conveyer belts, bins, and so forth.

Check out Mattheij's writeup in two parts for more information. It starts with an overview of the story, followed up with a deep dive on the software. He's also tweeting about the project (among other things). And if you look around a bit, you'll find bulk LEGO brick auctions online—it's definitely a thing!
