Abstract: A method of additive manufacture suitable for large and high resolution structures is disclosed. The method may include sequentially advancing each portion of a continuous part in the longitudinal direction from a first zone to a second zone. In the first zone, selected granules of a granular material may be amalgamated. In the second zone, unamalgamated granules of the granular material may be removed. The method may further include advancing a first portion of the continuous part from the second zone to a third zone while (1) a last portion of the continuous part is formed within the first zone and (2) the first portion is maintained in the same position in the lateral and transverse directions that the first portion occupied within the first zone and the second zone.

Abstract: An apparatus and a method for powder bed fusion additive manufacturing involve a multiple-chamber design achieving a high efficiency and throughput. The multiple-chamber design features concurrent printing of one or more print jobs inside one or more build chambers, side removals of printed objects from build chambers allowing quick exchanges of powdered materials, and capabilities of elevated process temperature controls of build chambers and post processing heat treatments of printed objects. The multiple-chamber design also includes a height-adjustable optical assembly in combination with a fixed build platform method suitable for large and heavy printed objects.

Abstract: A method of aligning a chiral nematic liquid crystal (103), the method comprising depositing a first chiral nematic liquid crystal (103) onto a first substrate (102), positioning a second substrate (104) on top of the liquid crystal (103) to form an initial layer structure and then applying rolling pressure to at least one of the substrates (102, 104) of the initial layer structure to create a final layer structure in which the first chiral nematic liquid crystal (103) is aligned with a helical axis substantially perpendicular to a local plane of the first substrate (102). Aspects of the invention provide optical filter materials for laser protection applications, LED emission filtering and lighting, augmented reality display coatings.

Abstract: The invention is an optical system for up-conversion of SWIR images into visible images. The optical system of the invention comprises a liquid crystal optically addressed spatial light modulator (LC-OASLM), which acts as an optical valve, and two optionally GRADIUM lenses to reduce the size and complexity of the optical setup. In embodiments of the invention, the photosensitive layer is replaced by a photodiode or array of photodiodes and the liquid crystal layer is replaced by an array (film) of organic light emitting diodes which emit light at the VIS by collecting SWIR light or by a fluorescence layer with sensitivity in the SWIR range.

Abstract: According to an aspect, a substrate for a display apparatus includes: a first substrate; a translucent coloring layer that includes a plurality of color regions and that overlaps with the first substrate; a first translucent resin layer that overlaps with the first substrate at boundaries of the color regions; and a light shielding layer that overlaps with the first translucent resin layer on an opposite side to the first substrate side. A width of the light shielding layer in a direction parallel with the first substrate is equal to or smaller than a width of the first translucent resin layer in the parallel direction on a cross section vertical to the first substrate.

Abstract: A transmitter that is difficult to be affected by structural constraints is a transmitter that transmits a signal to a receiver by changing an amount of light emitted, and the transmitter includes: a control unit that generates a control voltage corresponding to a signal to be transmitted; a reflector that reflects sunlight; and a liquid crystal board that receives reflected light that is sunlight reflected by the reflector and changes, according to the control voltage, the amount of light emitted toward the receiver, by allowing the reflected light to pass through the liquid crystal board.
