Abstract: Optical systems that can produce digitally switchable optical power, optical pathlength, or both. It can apply to reconfigurable wide-angle optical systems that are compact, light-weight, and light-efficient. Architectures that increase pathlength can utilize polarization splitters to produce an additional round- trip of one or more optical cavities. Changing the focus distance of synthetic imagery in augmented/virtual reality systems is an example of an application where the techniques taught herein are particularly well suited. Passive double-cavity systems can be used to increase the throughput and decrease the stray-light/ghosts in polarization-based compact wide-angle lenses.

Abstract: A head-up display device (10) includes: a light source (12); a liquid crystal display device (13) that controls a transmittance of light from the light source (12) and displays an image on a display member (15); an illuminance sensor (18) that measures an environmental illuminance; and a control circuit (20) that uses a measurement result of the illuminance sensor (18) to control a brightness of the light source (12). The control circuit (20) controls the brightness of the light source (12) to prevent a border caused by a difference between a black brightness of a display area displayed on the display member (15) by the liquid crystal display device (13) and a black brightness of a background around the display area from being visually recognized.

Abstract: A composite article having a conductive layer on at least a portion of a flexible substrate. Electrical connectivity between various portions of the substrate can be obtained through this conductive layer. The conductive layer comprises a conductive surface, and there is a patterned layer on at least a portion of a first region of the conductive surface. The patterned layer comprises a conductive material having a surface roughness, and is in electrical contact with the conductive surface. An overcoat layer is present on at least a portion of the first region, such that the overcoat layer has a thickness less than the surface roughness, such that the conductive layer within the first region is covered by the overcoat layer, and such that at least a portion of the patterned layer substantially protrudes above the overcoat layer. The protruding portion permits electrical contact with the patterned layer, and via the conductive layer to other parts of the patterned layer and/or electrically conductive connectors to external electronic devices. Methods for forming the composite article are also disclosed. Methods of making such composite articles are also disclosed.
