How an Alabama design and engineering company helped Regions Tradition go 3D on the tee – Alabama NewsCenter
Theyre noticeable to spectators in person and to viewers on TV: the unique 3D Regions Tradition tee markers in the shape of the banks iconic bike brand.
Forrest Satterfield created them in 2015 because, well, someone asked if it was possible. Thats what Satterfield likes to do take the ordinary and make it extraordinary.
When the Bruno Event Team (which coordinates the Tradition) first reached out to me, Id just received my first funding from an investor $25,000, Satterfield said. I had one 3D printer, one scanner, and I was running everything out of my apartment. I was terrified. I didnt know how I was going to pay the rent.
Six years later, Satterfield Technologies is flourishing, responding to a global pandemic by creating N95 face masks for front-line health care workers with a 3D printer.
Satterfield majored in biomedical engineering at the University of Alabama at Birmingham, where as an undergrad he learned to merge medicine, science and business. A key turning point was a class project focused on dune buggy races. He was tasked with creating a business model and made his first pitch atBarber Motorsports Park, where he came onto the radar of the Bruno Event Team that manages the Indy race there, as well as the Regions Tradition and the SEC Baseball Tournament.
Satterfield quickly pivoted, from business pitch to business partner for the Bruno team.
We havent turned down a project yet, Satterfield said. Our motto is: seek stories, solve problems.
When people ask for something unique, he produces.
For Birminghams Sidewalk Film Festival, Satterfield Technologies created the popcorn bucket trophies given to award winners. For the Tradition, he created a 360-degree immersive video one can use with a virtual reality device to get a feel for the Greystone Golf & Country Club course, where the PGA Tour Champions major is held each year.
Another project created a water filtration system, turning undrinkable water into clear, pristine liquid for safe consumption sans an actual filter.
And, at the onset of the global pandemic, Satterfield Technologies created the custom-fit, 3D-printed N95 masks for emergency room doctors and nurses.
Before, the masks came from overseas and the supply system was disconnected, he said. I wanted to dive into what made them work, strip away everything else, and it took about a month to develop. We were able to produce high-quality products in a 30-by-30 manufacturing room, and we believe they outperform all others on the market.
Satterfield Technologies calls itself a modular adaptive manufacturing company. While hes branched out in a dozen directions, the heart and soul of this small business remains the medical side.
Our main focus is on affordable medical devices, Satterfield said. Everything we do is through the lens of how it affects your health. So many things we use today have unintended negative consequences. Were changing that. By closing the gap, youre able to communicate between the hard science and the hard engineering. We solve the tough problems without sacrificing long-term health.

UCLA Engineering In-Flight Conversation with SpaceX Crew 2 aboard the International Space Station – UCLA Samueli School of Engineering Newsroom
Two UCLA mechanical and aerospace engineering students conducted a live interview today from Earth to space with aerospace engineering alumna and SpaceX Crew-2 mission pilot Megan McArthur 93 and mission commander Shane Kim Kimbrough.
The SpaceX Crew Dragon spacecraft Endeavour carrying four astronauts from three countries successfully launched on April 23 from NASAs Kennedy Space Center in Florida for a six-month mission aboard the International Space Station.
The 20-minute Skype interview by Anil Nair and Anneliese Peterson from UCLAs Laser Spectroscopy and Gas Dynamics Laboratory was livestreamed on NASA TV. A recording showing the interaction between students at the UCLA Samueli School of Engineering and the crew aboard the International Space Station can be viewed in this YouTube video.
We followed up with Nair and Peterson post-interview to get their thoughts on the out-of-this-world experience.
Q: How do you feel about speaking with McArthur and Kimbrough, the pilot and the mission commander of SpaceX Crew 2 respectively?Nair: I felt honored to have this unique opportunity to talk to Megan and Kim. Anneliese and I have both learned so much about space flight and travel in our classes, so it was great to hear about the astronauts experiences first-hand.
Q: Describe what it was like talking to people in space. How does it feel and sound differently or the same from calling someone on Earth?Peterson: Talking to the astronauts in space felt surprisingly similar to a regular video call, except that there was a slight delay because they had to uplink our audio from the ground to the Station. I loved how Megan wore a UCLA shirt for the occasion!
Q: What came to mind when you first saw McArthur and Kimbrough?Peterson: When their video first popped up on the screen and I saw them floating in microgravity I finally processed how unique the opportunity to speak directly with astronauts truly is. Their missions are so tightly scheduled that the fact that they took time to talk with us is incredibly generous, and we will remember this for the rest of our lives.
Q: What is the major takeaway from this interview?Nair: The interview was very inspiring, and it made me excited to be a part of the amazing growth in the space industry that Kim mentioned! I look forward to developing rocket engine technologies to help send future astronauts into space.
Q: What is the one question you wish you had asked but didnt get a chance to ask and why?Nair: I wish I got to ask the astronauts what their favorite microgravity trick is, and if they could demonstrate it for us. It was really impressive to see them doing tricks like flipping upside down during the interview!
Q: Anything else youd like to share with our audience?Peterson: It was incredible to hear that our question about how to redesign the ISS had never been asked before. Now I know if I ever get to design a new Space Station in a future job, I should add more storage space!
Anil Nair in the Laser Spectroscopy and Gas Dynamics Lab at UCLA, where rocket engine diagnostics are developed.Besides a shared passion for aerospace, Nair and Peterson have both been active leaders in the Rocket Project at UCLA, the student club that builds and launches liquid bi-propellant rockets out in the Mojave Desert.
Nair, a Ph.D. candidate in mechanical engineering and on his way to becoming a triple Bruin engineer, is currently doing research on detonation rocket engines and 3D-printed rocket engines. One of his goals is helping develop cutting-edge propulsion technology to enable future space travel. He served as Rocket Project president in his senior year and helped build the schools first liquid-fueled rocket. In his free time, Nair enjoys playing bass guitar and running on the beautiful UCLA campus.
Anneliese Peterson doing final engine checkouts before a hot fire of a LOx-Ethanol engine.Originally from the San Francisco Bay area, Peterson is the Rocket Project vice president and student ambassador tour guide for UCLA Samueli. A senior in aerospace engineering, Peterson is graduating this June and is considering working for Northrop Grumman at Space Park or SpaceX at Cape Canaveral as a launch engineer. Either way, Peterson plans to work as an engineer in the space industry. Shes even thought about her plans for retirement, hoping to teach physics or calculus. When shes not working with rockets, she loves painting, hiking and exploring Los Angeles.

Led by a Military Spouse and founded by a Military family, FLG is the leading educational courseware, content, and services provider powered by a global remote workforce. FLG entered the educational courseware industry in 2017 with a business model intentionally designed to fit the needs of Military Spouses and Veterans while keeping them competitive in their respective professional fields.
Today, FLGs social mission has expanded to include civilians because they, too, are experiencing drastic unemployment rates, largely due to COVID.
At FLG, teams of subject matter experts, project managers, and project directors work together to develop and review educational content based on the clients needs. The project-based work can range from weeks to months. Contributors are empowered with more control over their own schedule and are able to select projects seamlessly aligning with their calendar and capacity. There is a project at FLG for every phase of your career and every stage of your life.
Since inception in 2017, FLG is proud to have 69% of our workforce represented by women and 46% made up by Military Spouses. At a time when COVID has forced women out of the workforce, FLG has created a landing zone for those seeking portable, flexible, meaningful employment opportunities, especially in the STEM field.
As a Military Spouse and woman in engineering, after having my first child I found it difficult to continue a career in the profession that would allow the flexibility I needed. I started working as a subject matter expert with Freedom Learning Group while stationed in Germany. The companys flexible employment options allowed me to use the core engineering skills I mastered in problem solving, critical thinking, and project management to progress my career from subject matter expert to Executive Director. Employment with Freedom Learning Group has allowed me to have the career progression I desire without sacrificing the support I want to give my family.
Jill, Military Spouse and Executive Director
From home offices in 36 states and 10 countries, FLG contributors are furthering their career in their area of expertise while ensuring work-life balance. FLG was specifically founded to support a fully remote and flexible workforce not just because COVID forced us to operate this way.
I am a retired Naval Officer and a Military Spouse. As we moved to support my husbands career, I often had to trade meaningful work for a job while starting at the bottom of a company again and again. With FLG, I am able to stay competitive in my field of expertise even living in a spot with very limited job opportunities. My absolute favorite reason for working with FLG is the flexibility. It allows me to set a strong example for my daughters, as I can strike a work-life balance while supporting my familys needs.
Jenna, Veteran/Military Spouse and FLG Subject Matter Expert
FLG was founded on the unprecedented mission to provide more than just jobs but also connect its workforce to relevant career opportunities in their respective fields including science, technology, engineering, math and dozens of other disciplines.
Though fully virtual, the company culture is one based on bringing people together, creating hope, and inspiring change. And to inspire change, FLG is championing best practices for a remote, global workforce. To build the workforce of tomorrow, FLG has introduced Last Mile Training (LMT), focusing on retraining and upskilling subject matter experts while providing meaningful, multi disciplined career opportunities. FLGs LMT picks up where academia leaves off, advancing pathways to future career opportunities.
My experience with FLG is nothing but the right fit and a right on-time experience. Although every touchpoint has been virtual, I can sense the support and genuine relationships that are being shared. From day one, the FLG team made me feel welcome and made themselves and the resources that I needed available to me to be successful. In my upskilling and reskilling journey, in just three months, FLG has helped me build professional character by making me tap into unknown capabilities that I didnt know existed. Heres to an organization focused on ensuring that Military Spouses are hired and stay hired.
-Eudora, Military Spouse and FLG Salesforce Administrator
FLG will continue to create workforce-focused change for disconnected populations, especially women, leading to a path of economic freedom while challenging other companies to do the same.
Throughout May, FLG will celebrate Military Spouses and Veterans during Military Appreciation month. Be sure to connect with FLG on Facebook and LinkedIn to read our newly released White Paper on best practices for supporting a remote workforce to stay on top of new job openings.

Last month, we looked at rapid fire developments (RFD) in terms of flashover. This term encompasses occurrences such as flashover, backdrafts, and/or smoke explosions, but our focus is on flashover. We are going to continue our look at such phenomena with how we can aggressively cool the environment and the contents.
As a reminder, a flashover is the simultaneous ignition of everything within a room. It occurs when hot gases rise to the ceiling and spread out across the walls. These hot gases are what we call black smoke unburned particles of combustion. As it spreads out across the ceiling and the walls, it starts to heat up the items found within the room such as the paint on the walls, the furnishings, clothing, mattress, flooring material, etc., until they all reach their ignition temperature. Once they are all at their ignition temperature, a rapid fire development occurs, with everything becoming a big ball of fire. We are looking at temperature ranges between 1,000-1,500F, which requires a good amount of water to effectively cool it.

Flashover Strategy and Tactics
Firefighters Trapped in a Flashover
There are signs or indicators that are visible to us with our sight and with our tactile senses to warn us that flashover is impending. When these signs and indicators reveal themselves, firefighters must heed them and take aggressive action. These indicators are as follows:
Taking aggressive action against this particular RFD means to act in a smart way so that we gain the upper hand. There are two ways to effectively overcome and eliminate flashover: tactical ventilation and aggressive cooling with water.
Tactical ventilation will aid in the rapid removal of the unburned particles of combustion, the hot gases, the smoke and the heat. This can be accomplished in various methods with the most effective being vertical ventilation. As heat and smoke want to rise naturally, a vertical opening will allow them to rise and escape out of the structure. The key with vertical ventilation is placing the opening directly above the fire to create a direct chimney or travel path to the outside for the smoke and hot gases.
This must be coupled with aggressive cooling and application of water. This is where a handline, minimum 1 inches flowing a minimum of 150 gpm, should be used to effectively cool down the ceiling, walls, floors, and contents all at once. Having the proper nozzle is going to help with thisthis is where we could consider looking at smooth bore vs. automatic nozzles, but thats a topic for another time.
Aggressive cooling involves using a straight or solid stream of water from the nozzle. We do not want to use a fog pattern of any type when facing preflashover conditions. A straight or solid stream of water is going to allow us to effectively knock down the fire while at the same time reducing the heat inside from the extreme high temperatures to a much lower temperature. An example of this is with the UL FSRI tests conducted in February and March, where temperatures were recorded to have been reduced by about 1,300F with an aggressive attack with a smooth bore nozzle.
So how do we aggressively cool? We need to move the nozzle in a pattern that will hit the ceiling, the walls, and the floors all in a sequential and consistent fashion. Sweeping across the ceiling then straight down to the floor is one method, as well as sweeping the ceiling and also sweeping the floor. No matter what style chosen, it will involve movement, not a static application of water.
It also involves applying water to cool off the ceilings, walls, floors, and contents as we advance into the structure. This will require us to apply water to black fire, the unburned particles of combustion. Remember, they are contributing to the radiant heat against the ceiling, walls, floors, and contents. The black fire needs to be cooled a as well as the container that it is influencing. This will sound overly aggressive and will go against everything taught for the last number of years we never spray water at smoke. However, with the change in technology and with science, we need to spray water at the smoke to effectively cool it and render it weak in terms of contributing to a flashover.

Two security researchers detailed how they managed to remotely access parked Tesla vehicles, finding vulnerabilities in the systems open-source software component (ConnMann).
The duo published their findings on May 4, explaining how they were able to compromise parked Teslas, and control their infotainment systems over WiFi through the use of a drone. They said they could also open the EVs' doors and trunk, change the seats' positions, and the steering and acceleration modes, but they could not directly control the driving system of the car.
Essentially, they were able to press all the same buttons a driver could, just not actually switch the vehicle into drive mode.
The team consisted ofRalf-Philipp Weinmann of Kunnamon, Inc., and Benedikt Schmotzle of Comsecuris GmbH. They called their exploits TBONE, with the hope of sharing what they discovered at last year'sPWN2OWN contest. When that contest didn't take place due to COVID-19 closures, Weinmann and Schmotzle instead decided to directly contact Tesla to inform the company of these vulnerabilities, and then publish their findings online.
Before publishing the information, though, Tesla had the time to address the vulnerabilities, which can no longer pose a problem for the company's EVs.
For example, ConnMann released a new version in February 2021, and patches in the Git repository have been checked.
What's fascinating about this discovery is that everything could be done remotely, which is why Weinmann and Schmotzle used a drone to remotely access the Teslas the duo didn't even have to see the vehicles to hack into them, let alone be near them.
Explaining their motive, the two researchers said "Our mission at Kunnamon is to bring the power of cloud computing and emulation for testing embedded automotive systems, at scale."
It's not unheard of for people to find vulnerabilities in systems, especially when they're new or have recently seen software updates. Last year, someone managed to hack into their own car from a laptop, for instance.
Companies releasing new software, and products largely welcome such information. A number of bug bounty programs have circulated far and wide, which encourage hackers and tech enthusiasts to try and hack into or to discover vulnerabilities in systems by offering them money in exchange for their information.
In Tesla's case, in 2019 the company even offered one of its Model 3s to anyone who managed to hack its car.
Other good examples of bounty programs wereSony offering prizes of $50,000 or more to anyone who managed to find bugs in its new PS4, and Apple offering millions back in 2019 for anyone who could find vulnerabilities in its new systems.
Let's see if Weinmann and Schmotzle get anything from Tesla in return for their discovery, but if anything, they already gain recognition just for revealing their discovery.
