The invention relates to a radome having an essentially planar front panel which is of transparent design at the front and which is provided with a non-transparent layer on the rear, in particular for a radar sensor for a motor vehicle.

An optical element for a lighting device of an automotive vehicle. The optical element includes a first portion configured to transmit electromagnetic (EM) radiation therethrough, the EM radiation including visible wavelengths and an ablation process wavelength. Also included is a second portion configured to absorb at least the ablation process wavelength, the second portion being in contact with the first portion to define an ablation process boundary which separates a surface of the first portion from an adjacent surface of the second portion. A patterned optical coating is provided on the optical element such that the optical coating material is provided on at least a part of the surface of the second portion, but not provided on the surface of the first portion.

An optical illusion device and method of production is described. The method comprises producing a digital sculpt. A rendered visual image and a thinned digital sculpt are then produced from the digital sculpt. Next a digital thickness shell is produced from the thinned digital sculpt. Finally, the rendered visual image is employed to impart a lithophane depth map onto the digital thickness shell. The overall result is an optical illusion device comprising a negative image forming surface with a registered lithophane image imparted on thereon. When the optical illusion device is viewed from various angles (and with a light source placed behind it), the negative image forming surface appears to the viewer as a positive or convex model with a photographic image applied to the profiled surface. The illusion created is of a panning, three-dimensional photographic image, complete with improved detail due to the presence of the lithophane depth map.

Ophthalmic device molds made from a first portion of a molding surface formed from a first polymer and a second portion of the molding surface formed from a second polymer are described. When combined, the first portion and the second portion of the molding surface form an entire molding surface suitable for molding an entire surface, such as an anterior surface or a posterior surface of an ophthalmic device. Methods of manufacturing ophthalmic devices using these molds, including contact lenses, are also described.

Manufacturing a pre-molded stack of one or more lenses to be installable on a curved substrate such as a vehicle windshield includes placing a moldable stack of one or more lenses and adhesive layer(s) on a mold, applying heat and pressure to the moldable stack to produce a pre-molded stack of one or more lenses from the moldable stack, and removing the pre-molded stack from the mold. The pre-molded stack may have a compound curvature, which may match a curvature of the curved substrate. The mold may be formed using three-dimensional shape data derived from the curved substrate, such as by optically scanning the curved substrate.

A molded plastic part having a clear or translucent overmold and a substrate typically has a hard plastic substrate that can be opaque, translucent, or clear. The overmold is clear or translucent. Careful selection of materials provides for a substrate that retains its form after the thermoplastic overmold material, hot enough to flow, flows into the mold. A smooth area on the substrate provides a position for placing artwork.

The invention relates to a radome having an essentially planar front panel which is of transparent design at the front and which is provided with a non-transparent layer on the rear, in particular for a radar sensor for a motor vehicle.

Disclosed is a two-color molded front cover of a vehicular lamp. The front cover includes a light transmissive resin portion, and a black resin portion integrally molded on a part of a peripheral edge portion (first surface) of the light transmissive resin portion. A cover portion formed by a part of the black resin portion is formed on a peripheral side portion (second surface) of the light transmissive resin portion which is adjacent to the peripheral edge portion. Since a non-uniform black resin portion is not formed on the peripheral side surface of the light transmissive resin portion, the appearance of the light transmissive resin portion of the front cover is improved.

A transparent polyester film has low visible light transmittance of 5-50% by JIS K7705 testing standard and a high infrared-blocking rate of at least 90% by JIS R3106 testing standard, which is extruded from a kind of polyester resins obtained from 5-40 wt % of nanoparticle-based thermal insulation slurry and/or 0.005-0.1 wt % of nanoparticle-based black pigment slurry by weight of and to react with the polymerization materials to completely perform an esterification and a polycondensation, wherein the thermal insulation nanoparticle has a chemical formula of Cs.sub.XN.sub.YWO.sub.3-ZCl.sub.C with an average particle size of 10-90 nm and the nanoparticle-based black contains carbon black particles having a particle size of 20-80 nm.

A wafer-level method for packaging a plurality of camera modules includes (a) overmolding a first housing material around a plurality of image sensors to produce a first wafer of packaged image sensors, (b) seating a plurality of lens units in the first wafer above the plurality of image sensors, respectively, and (d) overmolding a second housing material over the first wafer and around the lens units to form a second wafer of packaged camera modules, wherein each of the packaged camera modules includes one of the image sensors and one of the lens units, and the second housing material cooperates with the first housing material to secure the lens units in the second wafer.
