Four dimensional (4D) energy-field package assembly for projecting energy fields according to a 4D coordinate function. The 4D energy-field package assembly includes an energy-source system having energy sources capable of providing energy to energy locations, and energy waveguides for directing energy from the energy locations from one side of the energy waveguide to another side of the energy waveguide along energy propagation paths.

A light-emitting device includes a board, a light-emitting element mounted on a surface of the board, a support member on which the board is placed, and a cover having a plate shaped main cover body covering the light-emitting element and a tubular portion which receives a light guide body that guides light emitted from the light-emitting element. The main cover body includes a base, a protrusion protruding from the base toward the board, and a ridge disposed on a protruded end of the protrusion. A step is formed by the protrusion and the ridge, and the protrusion and the ridge extend in a same direction along the base.

Devices utilizing holographic 4D plenoptic capture and display technologies to generate a light field function to provide glasses-less vision correction for observers with imperfect vision, and to project an image according to the generated light field function, and methods for calibrating a four-dimensional light field for a user with an uncorrected visual acuity.

The present disclosure provides an aerosol delivery device comprising a control device that is connectable with a cartridge and that can include one or more additional elements for improving one or both of visible indications of use to a user and resistance to infiltration of liquid into the control device. More particularly, the control device may include a light guide configured for transmitting to a window from a light source that is off-set from the window and a controller configured to direct a varying level of light from the light source. The control device may include one or more elements that are configured to limit infiltration of liquids into the control device and thus may be consider to be water-resistant or water-proof.

Embodiments described herein relate to a system for positioning indicator lights of a network device. The system may include a circuit board, which may include a circuit board edge positioned behind a front panel of the network device, two surfaces; and a side of the circuit board edge positioned between the two surfaces. The system may also include a hole through the circuit board near the circuit board edge, a cutout extending from a portion of the hole to the side of the circuit board edge, a LED coupled to the surface of the circuit board and adapted to emit light into the hole, and a lightpipe disposed in the hole to receive light emitted from the LED into a first end of the lightpipe. The lightpipe may direct the light from a second end of the lightpipe toward an opening in the front panel of the network device.

A light element for a bodywork component is provided. The light element includes at least one light source and a light guide, where the light guide forms a profile of an open cross-section, comprising: a first element made of injection-molded transparent polycarbonate, defining, along substantially the entire length of the profile, a zone (ZT) that is transparent to the light emitted by the light source; at least one second element made of injection-molded black polycarbonate, defining, along substantially the entire length of the profile, a zone (ZO) that is opaque to the light emitted by the light source;
the light source emitting light from inside the profile toward the transparent and opaque zones.

A vehicle includes a roof, an opening in the roof, and a window that is located forward from the opening, wherein the window has an upper end and the window is free from non-translucent structures near the upper end. A movable panel is connected to the roof for movement forward and rearward relative to the roof between a closed position and an open position. A seal is connected to the movable panel. The seal engages the window when the movable panel is in the closed position and the seal is disengaged from the window when the movable panel is in the open position.

The present disclosure provides an image capturing apparatus, including: a light source module configured to emit an incident light, wherein the light source module has a first surface and a second surface opposite to each other; an LCD module having a first surface and a second surface opposite to each other, wherein the second surface of LCD module faces the first surface of light source module, an air gap is formed between LCD module and light source module, and LCD module comprises a scattering layer for scattering the incident light; a light-transmitting cover plate having a first surface and a second surface, wherein first surface of the light-transmitting cover plate is configured to contact with an object to be captured, and second surface of the light-transmitting cover plate faces first surface of LCD module; and a sensor module configured to collect incident light reflected by light-transmitting cover plate.
