Top 5 Design Considerations for Human-Machine Interfaces > ENGINEERING.com | Colored Polycarbonate Sheet

Here’s a top-of-the-line X-Lite X-802 Carlos Checa replica helmet. Part of the decal is still on the sheet in the water bath:

Boiling heat transfer is used in many applications, including the production of electricity, chemical processing, and high-heat flux thermal management. Due to its prevalence, and the important role it plays in numerous industries, the enhancement of boiling heat transfer has been studied for decades. During boiling, heat is transferred from a hot surface to a cooler fluid by (1) evaporation across liquid-vapor interfaces, (2) transient conduction, and (3) the micro-convection generated by the nucleation, growth, and departure of vapor bubbles1,2. The efficiency of boiling is quantified by the heat transfer coefficient (HTC), defined as the ratio of the surface heat flux to the superheat temperature, the temperature difference between the solid and the saturated fluid. During boiling, there is a finite rate at which heat can be dissipated from any surface. This maximum is the critical heat flux (CHF). CHF, also referred to as the boiling crisis, occurs when the production of vapor cannot be adequately balanced by the amount of liquid returning to the heated surface. When this occurs the surface undergoes dry-out, where an insulating layer of vapor blankets the solid surface. This leads to an immediate, uncontrollable, and drastic increase in surface temperature with dangerous and potentially catastrophic consequences, such as the destruction of electronic components or the meltdown of a nuclear reactor.

The split, sliding front center armrest allows row-one occupants to individually adjust each half of the armrest to their liking, and concealed underneath it is a cubby with a cupholder and additional storage space. Another cupholder is located under a flush-fitting cover next to the rotary transmission controller.

“I couldn’t be happier with the situation that ended up out of this cool old building. For someone who hasn’t gotten to do this before, it was a dream to do it,” he said.

Once the helmets are molded, they are staged and ready for sanding, painting or decals. Notice that all of the “holes” in the helmet are ready for vents and other parts; this is done in the molding process:

An array of advanced driver-assistance systems (ADAS) are fitted as standard or offered as optional equipment and designed to make every journey in the Range Rover Velar safer and more comfortable.

We drove around the building’s perimeter. “This is something that Steve cared about passionately,” Ive said. “There is a bittersweetness here, because this is obviously about the future, but every time I come here it makes me think of the past as well—and just the sadness. I just wish he could have seen it.” We went to have lunch with Newson, in a twenty-thousand-square-foot room built as a miniature test run of the future campus cafeteria. ♦

Hours after the joint committee’s vote, Womack and U.S. Rep. John Yarmuth, D-Ky., introduced the Bipartisan Budget and Appropriations Process Reform Act of 2018. It contains "the Joint Select Committee’s bipartisan recommendations relevant to the House of Representatives," the lawmakers said in a joint news release.

Even though it’s not exactly the widest out there, Honor 8C’s notch looks just as bad as that of any other similar smartphone. It houses the earpiece (with a notification LED hidden behind it), the usual array of sensors, and of course, the front-facing lens. If Huawei had to put a notch, I would’ve preferred one with the ‘waterdrop’ style. But at least you can mask the notch via a simple option under the smartphone’s settings, so you don’t have to live with it.
