Abstract: A glass-based assembly includes a glass or glass-ceramic substrate comprising a surface. The surface has flaws, such as a population of small cracks extending into the surface, whereby the substrate is weakened relative to ideal strength thereof. The assembly further includes a coating coupled to the substrate and overlaying at least some of the flaws. Ultimate strength of the substrate with the coating coupled thereto is greater than that of the substrate alone, without the coating.

Abstract: Techniques for capturing spoken user inputs while a device is prevented from capturing such spoken user inputs are described. When a first device becomes incapable of capturing spoken user inputs intended for a system, a second device, for capturing such spoken user inputs, may be identified. The second device may be identified based on the second device being connected to a same vehicle computing system as the first device. The second device may be enabled to capture spoken user inputs, intended for the system, until the first device is again able to capture such spoken user inputs.
