A method for mounting functional elements in a lens includes mounting the functional elements on a foil, applying a closed contour alignment surface of an alignment tool having a central opening surrounded by the closed contour on the foil portion opposite to the mounted function elements, applying underpressure on the central opening to maintain the foil portion with the mounted functional elements on the alignment tool, cutting a flap including the foil portion and supporting the functional elements out of the foil, positioning and aligning the flap through actuator, fixing the position of the flap against the adjacent foil surface, embedding the foil with the mounted functional elements in a predetermined distance to the front surface of a mould, and casting and curing the lens with the embedded foil.

An imaging system includes at least one laser light source having a wavelength in the visible spectral range and a beam guidance element with high solarization resistance at high beam power densities. The invention also relates to the use of the imaging system, in particularly in projectors and in material processing.

A device for day lighting the interior of structure deploys reflective louvers that are spaced apart in stacks. The louvers include a coating or multilayer structure that is operative to reflect visible light but transmit IR light through the louver. The louvers also have a retro-reflective structure to return the IR light by reverse reflection in the opposite direction of the incident light, which is back toward the sun. The interior of the structure is more uniformly illuminated with visible light while the louvers and interior are not heated by IR light or radiation from the sun.

Provided is a display device including a light guide plate; a reflective prism configured to reflect an imaging beam toward the light guide plate, wherein the imaging beam reflected by the reflective prism travels within the light guide plate at an angle greater than a critical angle of the light guide plate; and a diffraction grating configured to diffract the imaging beam traveling within the light guide plate to an angle less than or equal to the critical angle of the light guide plate, wherein the reflective prism includes a first surface in contact with the light guide plate, and a second surface configured to reflect the imaging beam.

A vehicular frameless interior rearview mirror assembly includes a mirror head and a mounting portion. The mirror head includes a mirror reflective element and a mirror casing. The mirror reflective element includes a glass substrate having a planar front side and a planar rear side. No portion of the mirror casing overlaps the planar front side of the glass substrate of the mirror reflective element. A camera is disposed within the mirror casing. With the mounting portion of the mirror assembly mounted at an in-cabin side of a windshield of a vehicle, the camera views a driver of the vehicle, and when the mirror head is moved by the driver of the vehicle to adjust the rearward view provided by the mirror reflective element to the driver, the camera moves in tandem with movement of the mirror head. The camera is part of a driver monitoring system of the vehicle.
