A dark field projection display includes a light source, a spatial light modulator, and an optical system for directing light from the light source onto the spatial light modulator. The optical system includes a plurality of optical subsystems and a plurality of reflectors. Each of the optical subsystems has an input aperture and is arranged to image light from the light source, the subsystems forming a spatial distribution of source images whose relative positions are different from the relative positions of the input apertures. Each of the optical subsystems further includes a plurality of reflectors disposed at the relative positions of the source images. Each of the reflectors is arranged to reflect light from a respective one of the subsystems onto the spatial light modulator.

An optical device which is suitable for use in a projection display comprises a spatial light modulator, such as a liquid crystal device, with a microlens array disposed on its front surface. The microlenses are of convergent type, such as lenticules. The spatial light modulator is of the reflective type and comprises a plurality of rear reflectors, each of which has convergent optical power in at least one direction. The reflectors are arranged such that, for a given direction of illumination, each reflector forms an image of the aperture A of a microlens on the aperture B of another microlens or at a different position on the same microlens. When used in, for example, a projection display, light losses caused by vignetting are reduced.

A method and system for automatically holding and authenticating a configuration change payload job. An upgrade payload file can be transmitted to a rendering device as a rendering job via a print submission protocol. The upgrade payload file can be detected by a configuration change detection and hold module configured in association with the rendering device upon receiving the rendering job. The rendering job can be automatically held at the rendering device until an authenticated user releases the rendering job. The held rendering job can be also automatically deleted after a predetermined time period. The configuration change detection and hold module can be enabled and/or disabled by the authenticated user in order to prevent an unauthorized and accidental system upgrade and configuration change.
摘要:
A method for processing a print job includes: a) processing printer description language (PDL) image data for a select page of a print job to form raster image data for the select page, processing of the PDL image data and storing the raster image data in a RIP orientation; b) processing the raster image data for the select page to form bitmap image data for the select page, transforming the raster image data from the RIP orientation to a print orientation and storing the bitmap image data in the print orientation; and c) printing the bitmap image data arranged in the print orientation on a target substrate page to form a printed substrate page for the select page of the print job. A printing platform associated with the method includes a storage device, a RIP module, a rotator module, and a print engine.

摘要:
A method for processing a print job includes: a) analyzing printer description language (PDL) image data for a print job; b) determining a raster image processor (RIP) orientation for the print job based at least in part on the analysis of the PDL image data, the RIP orientation being selected from a landscape orientation and a portrait orientation; and c) processing the PDL image data for each page of the print job to form raster image data for each page in the RIP orientation and storing the raster image data in the RIP orientation. A printing platform associated with the method includes a parser module, a controller module, a storage device, and a RIP module.
摘要:
A method and apparatus for forming elongated composite structural members with a desired cross-sectional geometry as taken transverse to the length of the member. An apparatus may include a base with a substantially elongated mandrel mounted thereon. One or more rollers configured to at least partially complementarily engage the mandrel are configure to roll over and press a plurality of plies of composite material onto the mandrel. The rollers may be configured to form intermediate structures which partially conform to the mandrel prior to forming the final structure which substantially completely conforms to the geometry of the mandrel. The rolls serve to both form and debulk the structure. The present invention enables the formation of elongated structural members from resin impregnated materials while maintaining the materials in a substantially uncured state. The formed members may then be cocured with a skin or other composite structure.

A method and apparatus are provided for forming elongated composite structural members with a desired cross-sectional geometry as taken transverse to the length of the member. An apparatus may include a base with a substantially elongated mandrel mounted thereon. One or more rollers configured to at least partially complementarily engage the mandrel are configured to roll over and press one or more plies of composite material onto the mandrel. The mandrel may be disposed on a rotary table and configured to exhibit a curved elongated geometry to form at least partially curved or arcuate elongated members. The present invention enables the formation of elongated structural members from resin impregnated materials while maintaining the materials in a substantially uncured state. The formed members may then be cocured with a skin or other composite structure.

Interferometry apparatus which comprises a measurement light beam (2a, 2b) and a reference light beam (2c, 2d) which interact with each other to cause a spatial fringe pattern (24). An optical device (12) is provided which interacts with the spatial fringe pattern (24), such that light is spatially separated into different directions (30, 32, 34, 36). The intensity modulation in two or more directions of the spatially separated light is phase shifted. The optical device may comprise, for example, a diffractive device, a refractive device or a diffractive optical element.
