RLE Industries: Celebrating the New Era of Lumenera | Led Aluminum Architectural Profile

In a perfect world, these extruded profiles and brackets would behave like the LEGO bricks of our hey-day. In that world, profiles and brackets would only fit together in a limited range of configurations–each of which guarantees some sort of constrained relationship between those parts. Put better, as MIT Media Labs’ founder [Prof Gershenfeld] would say, “the metrology comes from the parts“. [Gershenfeld’s] best example of this concept is with LEGO bricks. Since each brick is properly dimensioned and only accepts certain configurations by which other bricks can connect to it, we can predict the sizes our our Lego configurations just by keeping track of all parts we used and how each part connects to the other. (Of course, this concept assumes that bricks are manufactured “ideally,” which , for all intents and purposes of the folks out there playing with LEGO, we’ll assume is true.) In that world, we wouldn’t need to measure anything, or, as [Gershenfeld] would say, “you don’t need a ruler to play LEGO.” Why? Because simply by inherent nature of the part metrology, assembling parts together would preserve an ideal geometric relationship between them. As a result we’d get two benefits: first, our components would fit together only in a limited number of configurations; second, once we assembled our components, their dimensions would directly reflect the CAD model.

In other words, those ESPN logos you see burned in to the screens at your local sports bar would not be covered.

Internally, the DA2 is where it really sets itself apart from other cases. While the vast majority of cases have dedicated bays for components which makes builds fast and easy, it tends to limit the usable space and limit flexibility. The DA2 uses what they call a ‘universal bracket’ with a track that is integrated into the frame. This design allows the brackets to fit anywhere along the sides of the frame. Other than the motherboard and expansion card (able to be flipped) components are able to be repositioned anywhere along the tracks improving customization and flexibility. Streacom says if it physically fits inside the case, there is going to be a way to mount it.

Leachables are trace amounts of chemicals originating from packaging, containers, medical devices or process equipment that end up as contaminants in medicinal products or food resulting in exposure to patients or consumers.

Those who join them are well rewarded. A political action committee supporting Chris McDaniel, the polarizing Mississippi Senate candidate, received $750,000 from Mr. Uihlein. Mr. McDaniel called Dick Uihlein “instrumental in the conservative movement,” adding, “there’s no way to overstate his importance.”

The prevailing wisdom has been that UV-C-band (generally 180–280 nm) LEDs still lacked the maturity for broad commercial deployment, although the potential for use in sterilization applications is extremely exciting. But LED manufacturers have struggled to produce UV-C LEDs with lifetimes longer than 10,000, or even 5000, hours. And power output and cost challenges remain.

While the world had to wait quite an unusual amount of time for the cause of death to be announced, there was plenty of speculation over what, exactly, caused the sudden death. Was it possibly related to the health issues that caused the band to cancel a majority of their 2017 European tour dates, blamed on "medical reasons associated with a back problem" on the band’s website, and all of their subsequent North American dates when it was deemed her recovery had not progressed far enough to allow her to participate? Nine months after her passing, on September 6, it was finally revealed that she’d died by drowning, the result of a "tragic accident," BBC News reported. With a blood alcohol level of over four times the legal limit for driving, she’d simply sedated herself, with no evidence of injuries or self-harm.

Related hired the firm, but at a meeting with Thomas Woltz, the owner of N.B.W., Ross asked for a new landscape. “I said, ‘Throw those plans out!’ ” he recalled. He described Woltz’s face falling, and added, “Nice young kid.”

The rastered laser and the argon purge available in the Z analyzer allows measurement of less than 1% of Fe in aluminum alloys. Averaging of multiple test locations is highly critical, as iron clustering is seen in some cases. If reference standards in the target concentration range are used, the Z is capable of quantifying Fe content down to 0.05%.

Here, this profile was chopped with a chop saw. Unfortunately, since I can’t control the tilt angle of my chop saw, all parts chopped with this tool will have a slight deviation from 90-degrees at their chopped end. If I fixture the profile end to the surface of the bottom profile, I’m effectively using the cut end as a reference. Since my reference is slightly off from the nominal 90-degrees, so too will my profile when it’s fixtured this way.
