Given that these went straight to backers, and would have required the final die cast parts to test in the thermal chamber, they probably had not gone to an NRTL at the point the article had been written.
This product is about at the point of DVT in development flow, and therefore would be sent to testing about now. But, instead, being sent to backers.
PS, not a hypothetical circumstance for me. I've previously certified a number of luminaires under UL and CB Scheme. I was the technical chair of ANSI C136.37 for several years, and on the working groups of several other standards.
There are a number of pressureless casting techniques available. Investment casting is widely used, for instance. https://www.harmonycastings.com/ is a fancier example.
For this specific application, the manufacturing method determines the porosity of the material, and therefore the heat transfer.
CNC prototype parts will have better heat transfer than pressure die cast, and the pressure die cast will perform better than pressureless cast parts.
We changed the entire family diet in part to help him not develop any complexes around food.
We would like to get him in the 5's, and I believe we'll get there. He was below 6.5% every checkup so far except the most recent one.
Between honeymooning and growth hormones, it's difficult to keep him in range from 10pm to 3am, while also not triggering a low after his stomach is empty.
1. Insulin helps get sugar into cells. Glucagon gets stored sugar out of the liver into the blood. Diabetes management in 2025 only deals with supplying external insulin.
2. There are several variants of diabetes. Type 1 is an autoimmune disorder where the body attacks the cells that make insulin.
3. Too much insulin equals all the sugar getting sucked out of your blood and lymph and into cells. This is really bad in an acute way. Your brain cannot run without sugar. Accidentally give yourself too much insulin for the sugars and wind up dead or in a coma in short order.
4. Highs are also bad, but generally in a less acute way. There are exceptions, but being too high with blood glucose for a period of time doesn't have the acute risks of being too low. Diabetics (or their caregivers) carry around quick absorbing sugar sources to help against a low.
5. The peak action (fastest reduction in blood glucose level) of the common insulin, in the way we dose it, peaks 90 - 120 minutes after the dose. The long tail is about 5 total hours of action from the point of dosing. So you should give insulin in advance of when you expect digestion to move glucose into your bloodstream. This is tricky. Also, as insulin ages, the peak of the action happens later. If a new vial is 90 minutes, an nearly empty vial might be 120 minutes after dosing for peak action.
6. CGMs, the on-body instrument in question here, are both flakey and amazing. There's a novel of good and bad here. I'm glad they exist, they can be cantankerous. They are a tiny potentiostat, if that is something you happen to be familiar with.
7. Very high blood sugar is treated with extra insulin to overcome the osmotic pressure of having too much glucose in the bloodstream. There's also a lot of chemistry here (glycocalyx to get you started). If your blood sugar is high you generally need more insulin to get past the hysteresis effects. Once the blood sugar starts to come down, that extra insulin is still around, and can cause a dramatic low. CGMs let you observe this, and "catch the low" by eating sugar to replenish the baseline sugar trapped in circulation.
8. Diabetes management is challenge every day, multiple times a day. Especially with small child who doesn't communicate to you about what they believe about their blood sugar. This is my personal circumstance.
9. Endocrinologists have suggested some wild stuff to my wife and I. For instance, keep a tube of cake icing around, as you can administer it rectally to a child who is passed out (or worse) from a deep low blood glucose. This is how poor the standard of care can be.
Father of 4.5 YO son with Type 1 diabetes, and materials engineer by education.
Our almost 5 year old has had T1D for two years. We ended up going the way of a controlled lower carb diet for our entire family. Other than the greatly increased cost to eat this way, it has been transformative for diabetes management of our son, the amount of sleep we get, and the lessened risk of aggressive lows.
We've managed to keep our sons A1C in the 6-7% window after we changed our diet to be heavily carb controlled.
Most smaller firms will require a retainer. $5k is fairly common. I've been able to work with several large firms for work, and several smaller firms for personal stuff.
Personally, I much prefer the larger firms. In general their work product, responsiveness, and timeliness is well ahead of small firms. They aren't even that much more expensive for some things. Unfortunately I don't know what the retainer $$ would be, if any, for a larger firm.
As the (non lawyer) who fell into managing all US legal firm interactions for my day job, I support this list.
If you are comfortable with legal documents; have a law dictionary to understand what specific language means; and read historical case law on the topic in question, you will be well prepared to have a seat at the table with your attorneys.
Helmholtz absorbers have been used for some time in built spaces. Look for a pattern of slats or holes like perfboard, often on the rear wall of the space. Lecture halls, museums, performing arts, and the like.
Son of a COBOL dev... All this virtualization mess, minus the extra Java layer, started back in the 90s, courtesy of Unisys. I remember my dad pulling his hair out when I was in High School, though I did not understand why back then.
BACnet allows multiple PHY implementations, including 802.3
I suspect that 802.3.cg is also kosher, but haven't looked in detail. It's been 5 years since I looked seriously at whether BACnet was the correct solution for a product family.
Practical examples from a US perspective, where the existing customer has a strong anchor for timely delivery:
1. McMaster-Carr couriers tons of stuff to industrial and commercial facilities. Partner with one of their exist carriers.
2. Local automotive repair shops need parts delivered.
3. Durable medical equipment delivery.
4. Overflow capacity on your local contract FedEx routes.
5. Emergency runs for event or wedding planners.
6. Fresh produce, greens, and fish for restaurants.
7. Airport to hotel lost luggage courier.
