Toughened glass

Toughened or tempered glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the inner surfaces into tension. Such stresses cause the glass, when broken, to crumble into small granular chunks instead of splintering into jagged shards as plate glass (aka: annealed glass) creates. The granular chunks are less likely to cause injury.

As a result of its safety and strength, toughened glass is used in a variety of demanding applications, including passenger vehicle windows, shower doors, architectural glass doors and tables, refrigerator trays, mobile screen protectors, as a component of bulletproof glass, for diving masks, and various types of plates and cookware.

Properties

Toughened glass is physically and thermally stronger than regular glass. The greater contraction of the inner layer during manufacturing induces compressive stresses in the surface of the glass balanced by tensile stresses in the body of the glass. For glass to be considered toughened, this compressive stress on the surface of the glass should be a minimum of 69 megapascals (10,000 psi). For it to be considered safety glass, the surface compressive stress should exceed 100 megapascals (15,000 psi). The greater the surface stress, the smaller the glass particles will be when broken.

Console (video game CLI)

A console is a command line interface where the personal computer game's settings and variables can be edited while the game is running. Consoles also usually display a log of warnings, errors, and other messages produced during the program's execution. Typically it can be toggled on or off and appears over the normal game view.

The console is normally accessed by pressing the backtick key ` (frequently also called the ~ key; normally located below the ESC key) on QWERTY keyboards or the ² on AZERTY keyboards, and is usually hidden by default. In most cases it cannot be accessed unless enabled by either specifying a command line argument when launching the game or by changing one of the game's configuration files.

History

A classic console is a box that scrolls down from the top of the screen, and is found in most computer games. This style was made popular with Quake (1996). There are other forms of console:

Impulse (software company)

Impulse, Inc. is a software company responsible for making several 3D modeling and rendering applications. Most notably TurboSilver and Imagine for the Amiga computer. They were originally located in Minneapolis, Minnesota and later moved to Las Vegas, Nevada. After moving to Las Vegas they became more and more involved in creating software for casino video slot machines.
