    摘要: A solid imaging apparatus and method employing sub-pixel shifting in multiple exposures of the digitally light projected image of a cross-section of a three-dimensional object on a solidifiable liquid medium. The multiple exposures provide increased resolution, preserving image features in a three-dimensional object and smoothing out rough or uneven edges that would otherwise be occur using digital light projectors that are limited by the number of pixels in an image projected over the size of the image. Algorithms are used to select pixels to be illuminated within the boundary of each image projected in the cross-section being exposed.

    摘要: A telephone apparatus enables the approximate simultaneous transmission and reception of audio interleaved with image and graphical annotation signals, in data packet form, over an analog line which connects the apparatus to a switched telephone network. The audio data packets are transmitted at a periodic rate, during a first time interval, and the image and annotation data packets are transmitted during a second time interval, following the first time interval, enabling the simultaneous output of voice, image and annotation data at the receiver site. Control data packets, as needed, are also transmitted during the second time interval for end-to-end apparatus control. One feature enables the transmission of audio data packets at a first periodic rate, when in an image transmission mode, and at a second periodic rate, faster than the first periodic rate, when not in the image transmission mode.

    摘要: A pneumatic door closer with a protective external telescoping cylinder and angled handhold. Such a closer is generally outfitted with a structural tubular support that follows the telescoping and collapsing of the closer's piston and that has sufficient stiffness to limit the stresses imposed on the piston throughout its extension. The support provides a resistance to perpendicular force. Moreover, when the piston is collapsed within the exterior chamber, the support pivots to the exterior chamber with bushing(s) fixed to the end of the support that travel along the length of the exterior column as the closer telescopes or collapses, to permit continued smooth sliding motion throughout the extension stroke.

    摘要: A solid imaging apparatus and method employing build material transfer means effective to transfer solidifiable liquid build material from a first side of a radiation transparent build material carrier to a receiving substrate without entrapping air bubbles in layers of transferred solidifiable liquid build material and to cleanly separate the solidified build material from the radiation transparent build material carrier as each layer is formed during the layerwise building of a three-dimensional object. An expandable membrane forming an arcuate dome and a reciprocatible flexible film are employed to effect transfer of the solidifiable liquid build material.

    摘要: A solid imaging apparatus is provided that includes a replaceable cartridge containing a source of build material and an extendable and retractable flexible transport film for transporting the build material layer-by-layer from the cartridge to the surface of a build in an image plane. An operator using the device needs merely to remove a spent cartridge and replace it with a fresh cartridge to continue solid imaging virtually uninterrupted. The apparatus also includes the capability of withdrawing and inserting an imager without the operator having to perform a separate alignment step. A brush attached to the transport film and forming part of the cartridge provides for intra-layer removal of excess uncured build material. If desired, the apparatus can produce a fully reacted build. A high intensity UV source cures the build between layers. An injection molded build pad is designed to hold a build in an inverted position for improving the build. The invention also provides for tilting the build elevator to reduce air entrainment and for releasing the build from the image plane.
