Abstract:
Light guide structures that include a transparent plate having a first end and a second end; and a plurality of transparent light guide members, each transparent light guide member extending from the first end to the second end along one surface of the transparent plate and being configured to emit white light in response to light applied thereto are described.
Abstract:
A light emitting device, includes a light emitting diode unit on a substrate; a gas-generating species; an inert gas; a barrier; and a sealant; wherein: the sealant, barrier, and substrate define a protective chamber; and the light emitting diode unit, the gas generating species, and the inert gas are disposed within the chamber.
Abstract:
Printing apparatuses for detection of substrate alignment, methods for manufacture and use thereof, and substrates are disclosed. One printing apparatus may include a printing assembly having at least one conductive alignment sensor with a plurality of inductive coils configured to generate an electromagnetic field. The printing assembly may receive at least one substrate having at least one conductive portion and align the substrate such that the plurality of inductive coils and the conductive portion substantially overlap with each other to form an electromagnetic field having a direction from the at least one conductive alignment sensor to the at least one conductive portion. The direction of the electromagnetic field with respect to the conductive alignment sensor may form an angle. The conductive alignment sensor may be configured to detect a movement of the conductive portion when a change to the angle causes a current change through the plurality of inductive coils.
Abstract:
Methods, systems, caps, containers, and assemblies for a gecko-like container capping system are described. A gecko-like cap configured to cover an opening in a container may include an inner surface configured to mate with an opening surface of a container. Setae may be located on a surface of the cap and/or a surface of the container that are configured to oppose movement of the cap away from the container by creating an adhesion force between the inner surface and the opening surface. The cap may include one or more release mechanisms configured to deflect the inner surface away from the opening surface, thereby reducing the adhesion force such that the cap is removable from the container.
Abstract:
Methods and systems for controlling traffic pollution are disclosed. An environmental score and a financial incentive based on the environmental score may be provided. A vehicle having a pollution recording unit may be provided. The pollution recording unit may be configured to provide an environmental score based on the pollution behavior of the vehicle. A financial incentive may be determined based on the environmental score at a processing device communicatively coupled to the pollution recording unit. The financial incentive may be provided to an operator of the vehicle.
Abstract:
A backlight system includes a first light guide layer, first light sources, a second light guide layer and second light sources. The first light sources are configured to emit first light into the first light guide layer. The second light guide layer is arranged on a first surface of the first light guide layer. The second light guide layer contains light-excited fluorophores. The second light sources are configured to emit second light into the second light guide layer in synchronization with the emission of the first light sources.
Abstract:
Organic light emitting diodes (OLEDs) include a polymeric barrier coating that is a copolymer of ethylene and substituted vinyl constituents configured to protect the OLEDs from both oxygen and water. The substituted vinyl of the coating may be selected, in conjunction with the permeability properties provided by the ethylene, to include chemical structures, physical structures, and chemical functional groups that effectively and efficiently create a barrier towards both oxygen and water. Methods for producing and using the coatings are also disclosed.
Abstract:
Backlight systems including a core layer, configured to be flexible, and at least one light source are described. The core layer contains at least one light-excited fluorophore. The light source is arranged on an edge of one side of the core layer. Further, the light source is configured to emit first light into the core layer through the edge of the one side of the core layer. The core layer is configured to transmit the first light therein and to emit second light caused by the light-excited fluorophores irradiated by the first light from a first surface of the core layer.
