Abstract: A composite is provided to include an elastomer substrate comprising methyl groups. The composite may also include a layer of glass comprising SiO2 formed over the elastomer substrate. A method of fabricating the composite is provided. The method may include diffusing an ozone-rich gas into the substrate of an elastomer substrate comprising methyl groups. The method may also include exposing the elastomer substrate to UV radiation for a period of time. The method may further include converting a surface portion of the elastomer substrate into a layer of glass formed over the elastomer substrate.

Abstract: An electronic device may have input-output devices such as keyboard keys or other buttons. Components such as cameras and other devices may have trim structures. A housing may be used to form an enclosure for the components. Keyboard keys, trim structures, and/or other device structures such as housing structures may be provided with wear-resistant coatings. For example, a keyboard key may have a glyph such as an alphanumeric character formed from patterned layers of ink. To prevent wear to the key and glyph, the glyph may be coated with a wear-resistant coating. The wear-resistant coating may be formed from a polymer with embedded mineral particles such as aluminosilicate particles.

Abstract: An electronic device may be provided with input-output devices and other components such as optical components that emit light and optical components that detect light. An optical component covering structure may be interposed between an interior region of the electronic device and an exterior region that surrounds the electronic device. The optical components may be formed in the interior region of the electronic device. The optical component covering structure may overlap the optical components. The optical component covering structure may be configured to exhibit a flat visible light transmission spectrum. This neutral light transmission characteristic allows the overlapped optical components to emit and/or receive light through the optical component covering structure without imposing an undesired color cast. The optical component covering structure may include first and second layers with complementary light transmission characteristics.

Abstract: This disclosure is directed to an electronic identification card or electronic card having various features. The electronic card may include an integrated circuit and a contact plate for electrically interfacing with the integrated circuit. The contact plate may include an array of terminal electrodes that are offset with respect to the edges of the contact plate. The electronic card may be coated with a coating layer that extends at least partially over a ferromagnetic element or film. The electronic card may also include a metal substrate having exposed chamfer portions that may provide a visual contrast to the coating layer and also improve the handling and use of the electronic card.

Abstract: This application relates to self-profiling friction pads for computing devices. In particular, the embodiments discussed herein describe self-profiling friction pads that have a naturally dome-shaped profile. In some embodiments, the self-profiling friction pads can be used as device feet for a computing device. Additionally, the self-profiling friction pads can be used to seal certain areas of the computing device such as a display or ventilation system. The self-profiling friction pads are configured to be deposited in a liquid state and form into a dome shape as a result of the material properties of the deposited liquid and the properties of the surface to which the liquid is deposited.

Abstract: Techniques and apparatus to provide improved visibility to user input devices, such as keys, are disclosed. In low light conditions, keys can be difficult to distinguish. For example, often keys have legends on them to visually distinguish them from one another, but in low light conditions it can be difficult for users to visually distinguish the different keys. The legends can be textual and/or graphic. Hence, according to one embodiment, light from a nearby display device can be used to provide illumination to the user input devices (e.g., keys). More particularly, in one embodiment, some light from the nearby display device can be directed towards and reflected from the user input devices (e.g., keys) to enhance visibility of the keys or the legends thereon.
