A mirror for a head-up display, in particular for a head-up display for transportation is disclosed. A head-up display comprising such a mirror is also disclosed. The mirror has a base body with a planar region and a rib arranged at a periphery of the planar region. A mirror layer is arranged on the planar region wherein the rib has an anti-reflective structure.

A rear backup system for a vehicle includes a rear backup video camera and a display device including a video display screen operable to display video images viewable by a driver of the vehicle. When a transmission of the vehicle is shifted into reverse gear to commence a backup event, video backup images derived from image data captured by the rear backup video camera are displayed at the video display screen of the display device. Display of the video backup images continues after shifting of the transmission out of reverse gear. Display of the video backup images at the video display screen ceases once a threshold condition is met. The threshold condition may include a threshold period of time elapsing after the transmission has been shifted out of reverse gear. The rear backup video camera continues to capture image data at least until the threshold condition is met.

A multi-camera vision system for a vehicle includes a plurality of cameras viewing exterior the equipped vehicle and at least one non-visual sensor sensing exterior of the equipped vehicle. Captured image data and sensor data are provided to a central data processor. At the central data processor, image data is fused with sensor data and processed in order to detect vehicles that are present external the equipped vehicle. The central data processor includes a digital signal processor operable to process data at a data processioning speed of at least 30 MIPS. Via processing at the central data processor of image data and sensor data, a potential hazard present exterior the equipped vehicle is determined to exist. The potential hazard arises from presence of rear-approaching traffic in at least one of (i) a side lane to the equipped vehicle and (ii) a rear lane to the equipped vehicle.

A fabrication process includes: 1) forming an object by 3D printing; 2) smoothing the object by applying a gel to the object to coat at least a portion of the object with a film of the gel; 3) subjecting the object coated with the film to vacuum; and 4) curing the film to yield the object coated with the cured film.

Methods of infiltrating a three-dimensional part with a resin are disclosed. The methods include designing a part to be printed, the part having at least one inlet and an infill pattern. The methods include using three-dimensional printing to print the designed part. The methods further include infiltrating the printed part using a resin delivered to an interior of the part via the at least one inlet to surround the infill pattern with the resin. The methods additionally include allowing the infiltrated resin to cure.

A printing system for printing a three-dimensional optical component, including a printing unit having a print head with ejection nozzles for ejecting droplets of printing ink, a measurement unit to measure optical properties of a pre-structure of the three-dimensional optical component, wherein the measurement unit includes at least one light source and at least one light detector, further including a process control unit for determining the difference between the measured optical properties of the pro-structure and target optical properties of the pre-structure. The present teachings further relate to a corresponding method.

An adjustable rearview device, especially a side-view mirror for a motor vehicle, has a mirror head, a mirror base and at least one joint device. The joint device is arranged between the mirror head and mirror base and includes at least one elastomeric element and an axis of rotation around which the mirror head can move. The mirror head is configured to move, particularly by rotating or folding relative to the mirror base, from a first functional position to at least one second functional position. In the first functional position, the elastomeric element holds the mirror head. In at least one second functional position, the elastomeric element is stretched or compressed. The adjustable rearview device has at least one electrical conductor, which extends at least between the mirror base and mirror head. The electrical conductor is elastically deformable at least in the direction of its longitudinal dimension.

A polygon mirror made of plastic is provided. The polygon mirror has a plurality of reflecting surfaces, a first surface intersecting the plurality of reflecting surfaces at a first side, a second surface intersecting the plurality of reflecting surfaces at a second side opposite to the first side, with a through hole provided to extend through the first surface and the second surface at a center of the polygon mirror. The polygon mirror includes a plurality of gate marks of injection molding. When viewed from an extending direction of the through hole, the gate marks are located on straight lines passing through the center and vertices of the first surface, and are rotationally symmetric with respect to the center.

A plastic reflective waveguide is manufactured using a soft transfer stamp formed in a first mold using a liquid injection molding process to provide the stamp with parallel wall surfaces having a zero degree draft angle. The soft transfer stamp is placed as an insert in a second mold utilized in a multi-stage thermoplastic injection molding process. A first thermoplastic injection molding stage molds a base part of the plastic reflective waveguide having parallel wall surfaces with a zero degree draft angle. The soft transfer stamp is removed from the second mold and a partially-reflective coating is applied to the base part. A second thermoplastic injection molding stage is utilized to create a secondary part of the plastic reflective waveguide. The raw plastic reflective waveguide is ejected from the second mold and subjected to additional manufacturing processes to realize a finished part meeting design requirements for size and form factor.

An interior rearview mirror assembly for a vehicle includes a mirror stay configured to attach at an in-cabin portion of a vehicle equipped with the mirror mounting system. The mirror stay is formed by injection molding a thermoplastic polymeric molding resin using a gas assist molding process. The thermoplastic polymeric molding resin includes a reinforced polyamide polymeric molding resin. A mirror head is pivotally mounted at a pivot element of the mirror stay. The mirror head includes a mirror reflective element and a mirror casing.
