An electronic device may have a housing with a display. A protective display cover layer for the display may have an image transport layer such as a fiber optic plate. The fiber optic plate may be formed from fibers. An extruder may form fiber bundles that each include a respective plurality of fibers distributed in binder material. The fiber bundles from the extruder may be fed directly to a block forming die. The block forming die may receive the fiber bundles from the extruder and output a unitary fiber block. The fiber bundles may remain heated in the block forming die such that the binder material of the fiber bundles seamlessly merges during formation of the unitary fiber block. A cutter can be used to cut off a layer of the unitary fiber block. This layer may be machined and polished to form the fiber optic plate.

A light pipe such as a fiber ribbon may be formed from fibers joined by binder such as extruded binder. The fiber ribbon or other light pipe may have bends. A light source may provide light to an input of a fiber ribbon that is guided by the fiber ribbon to a corresponding output. The output may be located in an interior portion of an electronic device or may be positioned so that light from the output exits the electronic device and illuminates external objects. The light source may have light-emitting devices on a substrate. The light-emitting devices may be vertical cavity surface-emitting laser diodes or other lasers and/or may be light-emitting diodes. Light-emitting devices may be arranged in discrete clusters corresponding to the locations of fiber cores in the fiber ribbon.

An optical device. The optical device includes a fibre optic plate having an input surface and an output surface, the fibre optic plate including a plurality of optical fibres; and a colour filter array including a plurality of colour filters formed on at least one of: the input surface, the output surface of the fibre optic plate.

A system, apparatus and method of improved measurement of the SPF factor of sunscreen compositions. In one embodiment, a method of measuring the protection of a sunscreen composition includes exposing skin to a known intensity of light, measuring the amount of remitted light from the skin, applying sunscreen to the skin, exposing the skin to which the sunscreen has been applied the known intensity of emitted light of the spectrum of light from which the sunscreen is intended to protect the skin, measuring the amount of light remitted from the skin, and calculating a UltraViolet-A Protection Factor (UVA-PF) of the sunscreen by comparing the amount of light remitted from the skin with the sunscreen to the amount of light remitted from the skin without the sunscreen.

An electronic device includes a housing and a display. The housing defines an interior cavity and includes an optically-transmissive housing component. The display is disposed in the interior cavity and is viewable through the optically-transmissive housing component. An optoelectronic component is disposed in the interior cavity. An optical fiber extends between a first end positioned adjacent the optoelectronic component and a second end positioned adjacent the optically-transmissive housing component. The optical fiber defines a non-linear optical path between the first end and the second end. At least a portion of the optical fiber is laterally offset from a lateral edge of the display.

A filtering apparatus formed by a plurality of channel systems. Each of the channel systems include an inlet port formed on an inlet side of the plate; no more than one outlet port formed on an outlet side of the plate; and a channel formed in the plate, the channel coupled to the inlet port and to the outlet port, wherein the ratio of the product of the capture area of the inlet ports of a channel system with the first transmissivity associated with the inlet ports to the product of the capture area of the outlet ports of a channel system with the second transmissivity associated with the outlet ports is greater than one. The channel system is configured to interact with objects of interest on a scale which is smaller than a value several orders of magnitude larger than the mean free path of an object of interest. Some plate embodiments are configured to interact with particles, such as air molecules, water molecules, or aerosols. Other plate embodiments are configured to interact with waves or wavelike particles, such as electrons, photons, phonons or acoustic waves.
