Abstract: A system such as a vehicle may have adjustable structures such as adjustable windows. Adjustable windows may have adjustable layers such as adjustable tint layers, adjustable reflectivity layers, and adjustable haze layers. Adjustable window layers may be incorporated into a window with one or more transparent structural layers such as a pair of glass window layers. Adjustable components such as adjustable reflectivity layers, adjustable haze layers, and adjustable tint layers may be interposed between the pair of glass window layers. Fixed partially reflective mirrors, fixed tint layers, and/or fixed haze layers may be used in place of adjustable tint, haze, and reflectivity layers and/or may be incorporated into windows in addition to adjustable tint, haze, and reflectivity layers.

Abstract: A window may have a structural window layers such as an inner glass layer and an outer glass layer. The inner glass layer may be a layer of tempered glass. The outer glass layer may be a laminated glass layer. The inner and outer glass layers may be separated by an air gap. One or more reflection suppression layers such as antireflection layers and/or circular polarizers may be incorporated into the window to suppress reflections of light from within the interior region off of the window back towards the interior region. The antireflection layers may be formed on one or both surfaces of the inner glass and one or both surfaces of the outer glass. An electrically adjustable layer such as a guest-host liquid crystal light modulator layer or other electrically adjustable optical component layer may be interposed between the outer glass layer and the air gap.

Abstract: Light-control panels including layered optical components are described in this application. An example of a light-control panel includes a first glazing layer, a second glazing layer, a third glazing layer, and a fourth glazing layer, a first switchable component extending between the first glazing layer and the second glazing layer, a thermal coating extending between the first glazing layer and the first switchable component, and a second switchable component extending between the third glazing layer and the fourth glazing layer. The second glazing layer and the third glazing layer have an air gap therebetween, such that the air gap forms a space between the second glazing layer and the third glazing layer.

Abstract: Various embodiments relate to sensing defects associated with a window. Furthermore, various embodiments relate to performing image processing to produce a corrected image of a scene based at least partly on data corresponding to the detected defects. In some examples, one or more lighting modules may be used to illuminate the window to facilitate detection of the defects by one or more sensor devices.

Abstract: A laminated glazing includes a first glass layer, a second glass layer, and a third layer between the first glass layer and the second glass layer. The third layer has an optical property that differs in a first region as compared to a second region, the first region being within five inches of one side of the laminated glazing and the second region extending from the first region toward another side of the laminated glazing.

An example of a light-control panel includes first and second glazing layers and first and second switchable components extending between the first and second glazing layers. The light-control panel also includes a thermal coating extending between the first switchable component and the first glazing layer and a filter extending between the first and second switchable components.

Abstract: An electronic device may include conductive structures having a visible-light-reflecting coating. The coating may include a seed layer, transition layers, a neutral-color base layer, and an uppermost layer that forms a single-layer interference film. The neutral-color base layer may be opaque to visible light. The interference film may include silicon and may have an absorption coefficient between 0 and 1. The interference film may include, for example, CrSiN or CrSiCN. The composition of the interference film, the thickness of the interference film, and/or the composition of the base layer may be selected to provide the coating with a desired color near the middle of the visible spectrum (e.g., at green wavelengths). The color may be relatively stable even if the thickness of the coating varies across its area.

The color may be relatively stable even if the thickness of the coating varies across its area.

Abstract: An electronic device may be provided with a display. The display may have a display cover layer. The display may have an active area with pixels and an inactive area adjacent to the active area. A reflective layer or a reflective portion of the cover layer may be formed in the inactive area and may have a reflectivity that matches a reflectivity of the active area of the display. The reflective portion may include texture or particles embedded in an ink layer. A PVD layer may be formed on the reflective layer and may have a color that matches a color of the active area. A polarizer layer may also extend across the active areas and inactive areas. In this way, an appearance of the inactive area may match an appearance of the active area when the display is off.

Abstract: An electronic device, such as a watch, has a housing to which a carrier is attached. The carrier has a first surface interior to the electronic device, and a second surface exterior to the electronic device. A set of electrodes is deposited on the exterior surface of the carrier. An additional electrode is operable to be contacted by a finger of a user of the electronic device while the first electrode is positioned against skin of the user. The additional electrode may be positioned on a user-rotatable crown of the electronic device, on a button of the electronic device, or on another surface of the housing of the electronic device. A processor of the electronic device is operable to determine a biological parameter of the user based on voltages at the electrodes. The biological parameter may be an electrocardiogram.

Abstract: An electronic device can include a housing component that can define an interior surface and an exterior surface of the device, a metallic film deposited on the interior surface and extending at least partially onto the exterior surface, and a ceramic film deposited on the exterior surface and at least partially over a portion of the metallic film on the exterior surface. The ceramic film can be in electrical communication with a portion of the metallic film deposited on the interior surface to form an electrical pathway from the exterior surface to the interior surface.

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.
