    Abstract: A system such as a vehicle may have windows with one or more conductive layers. The conductive layers may form part of an infrared-light-blocking layer or other layer. The infrared-light-blocking layer or other layer may be formed as a coating on a transparent structural window layer such as an outer or inner glass layer in a laminated window or may be embedded in a polymer layer between the outer and inner layers. Segmented terminals and elongated terminals that may extend past two or more segmented terminals may be coupled to the edges of the conductive layers. Using these terminals, control circuitry can apply localized ohmic heating currents and can make resistance measurements on the conductive layers to detect cracks.

    Abstract: Electronic device components that include a glass portion and a ceramic or a glass ceramic portion are disclosed. The ceramic or glass ceramic portions of the component may be located to provide desired performance characteristics to the component, which may be an enclosure component. In addition, regions of compressive stress may be formed within the glass portion, the glass ceramic portion, or both to further adjust the performance characteristics of the component. Electronic devices including the components and methods for making the components are also provided.
