A light beam forming module, in particular in the vehicle external lighting system, is in the form of a monolithic body formed of a plurality of contiguous cross-sectional segments, each of which includes an entrance surface facing the light source, an exit surface, and a first total internal reflection surface and at least another total internal reflection surface. A first total internal reflection surface is positioned downstream of the entrance surface, and at least one further total internal reflection surface has a shaped optical structure formed thereon.

A light harvester or collector collects solar radiation from an unshaded location adjacent a growing plant. The light harvester can be either imaging (e.g., parabolic reflectors) or non-imaging (e.g., compound parabolic concentrator). The concentrated solar radiation is projected into a light transmitter that conducts the light through the plant's outer canopy and into the inner canopy to a diffuser which disperses and reradiates the light into the inner canopy. The diffused light transforms a non-productive, potentially leafless zone of the plant into a productive zone so that more fruit can be produced per volume of land surface. The system can prevent transmission of infrared into the inner canopy so that the inner canopy zone is not heated and the amount of water lost to transpiration is reduced. The system can also modify other spectral components to affect plant development and to control pests and diseases.

Disclosed are transparent energy relay waveguide systems for the superimposition of holographic opacity modulation states for holographic, light field, virtual, augmented and mixed reality applications. The light field system may comprise one or more energy waveguide relay systems with one or more energy modulation elements, each energy modulation element configured to modulate energy passing therethrough, whereby the energy passing therethrough may be directed according to 4D plenoptic functions or inverses thereof.

Disclosed are systems and methods for manufacturing energy relays for energy directing systems and Transverse Anderson Localization. Systems and methods include providing first and second component engineered structures with first and second sets of engineered properties and forming a medium using the first component engineered structure and the second component engineered structure. The forming step includes randomizing a first engineered property in a first orientation of the medium resulting in a first variability of that engineered property in that plane, and the values of the second engineered property allowing for a variation of the first engineered property in a second orientation of the medium, where the variation of the first engineered property in the second orientation is less than the variation of the first engineered property in the first orientation.

A mirror assembly can include a housing, a mirror, and a light source. In certain embodiments, the mirror includes a light pipe configured to emit a substantially constant amount of light along a periphery of the mirror. In some embodiments, the mirror assembly includes a sensor assembly. The sensor assembly can be configured to adjust the amount of emitted light based on the position of a user in relation to the mirror. Certain embodiments of the mirror include an algorithm to adjust light based on the position of a user relative to the mirror, the level of ambient light, and/or the activation of different light modes.

A light beam emission system includes: a blower that forms a flow path in which aerosol flows; and an emitter that emits a light beam. At least part of the light beam propagates along the flow path of the aerosol.

A daylight redirecting window film formed by a flexible multi-layer film laminate with a total thickness of less than one millimeter and configured to be applied to an indoor-facing window surface of a building facade. The window film includes a pair of outer film substrates flanking a light redirecting core layer. The core layer includes a parallel array of channels defining total internal reflection (TIR) surfaces and linear optically transmissive structures protruding transversely thought the core layer and bonded to the outer film substrates. A light output surface of the outer film substrate which is disposed on an indoor-facing side of the laminate includes a two-dimensional pattern of light scattering microstructures which are configured to spread light at least in a plane that is perpendicular to the channels. The TIR surfaces intercept and reflect a portion of sunlight propagating through the core layer such that the window film redirects that portion of incident sunlight towards a plurality of divergent directions, forming relatively high bend angles.

This invention provides a system and method for sterilizing an ISO 594 female Luer fitting and an attached catheter using UV light. An optical plug can be inserted into a female Luer fitting, and UV-C light or a combination of UV-C and UV-A light can be radiated through the optical plug and into the female Luer fitting and attached catheter, thereby sterilizing the fitting and catheter. A sterilizer device can be used to hold the female Luer fitting and catheter, with an optical plug inserted into the female Luer fitting. The sterilizer device can include a UV light source that radiates UV light through the optical plug and into the female Luer fitting and attached catheter. A protective cover can be placed over the optical plug before inserting the optical plug into the female Luer fitting. The protective cover can be disposable.

First optical emitters are arranged to face the outer or inner circumferential edge. Second optical emitters are arranged to face the channel. A first optical receiver is arranged to face the outer or inner circumferential edge. A second optical receiver is arranged to face the channel.
