摘要:
A shingle mask has width mismatched to maximum-eye-sensitivity spatial frequency at reading distance or closer, so the mask is tiled with minimal patterning. A second invention facet forms a grid of optimum width—it corresponds to maximum sensitivity only if seen from much farther than reading distance. A third facet forms a 2D mask with width 0.25 to 2 inches, better 0.375 to 1.5, ideally 0.5 to 1 (progressively further from maximum sensitivity; as further increases help little, this enables bandfree printing without very large masks). A fourth facet optimizes width in terms of distance in the image, for aesthetics, speed and economy. Another facet automatically forms a mask that time-varies nozzle-use modulation. Another prints nontext images by a multinozzle pen, modulating use; still others by plural pens each with a multinozzle array, refraining from use of certain nozzles e.g. to simulate dynamic pen staggering.

The fulfillment request is fulfilled according to a solution selected from the redetermined solution set.
摘要:
A system for proofing a product over a network comprising a first computing device (110) that receives a product from a user, an operation module (191) that analyzes the product for print intent parameters, and a second computing device (185) that allows a user to finalize the product through a three-dimensional visualization, in which finalization by the user of the product causes a contract to be established between the user and a selected print shop provider (115).
摘要:
The present invention is directed to an apparatus and method for the stabilization and fastening of two pieces of tissue. A single device may be used to both stabilize and fasten the two pieces of tissue, or a separate stabilizing device may be used in conjunction with a fastening device. The stabilizing device may comprise a probe with vacuum ports and/or mechanical clamps disposed at the distal end to approximate the two pieces of tissue. After the pieces of tissue are stabilized, they are fastened together using sutures or clips. One exemplary embodiment of a suture-based fastener comprises a toggle and suture arrangement deployed by a needle, wherein the needle enters the front side of the tissue and exits the blind side. In a second exemplary embodiment, the suture-based fastener comprises a needle connected to a suture. The needle enters the blind side of the tissue and exits the front side. The suture is then tied in a knot to secure the pieces of tissue. One example of a clip-based fastener comprises a spring-loaded clip having two arms with tapered distal ends and barbs. The probe includes a deployment mechanism which causes the clip to pierce and lockingly secure the two pieces of tissue.
摘要:
A medical fastener (18), preferably bioabsorbable, is used for repairing torn soft tissue, particularly meniscal tissue (16). The fastener (18) can have an enlarged head (22) at the proximate end to engage meniscal tissue (16) adjacent to a tear (14), and a pointed distal tip (21) at the other end to ease insertion of the fastener (18) into the meniscus (16). The shank (20) of the fastener (18) bridges across the tear (14). Opposite ends of the shank (20) are secured in the meniscal tissue (16) by a medical adhesive, preferably bioabsorbable, and preferably at locations remote from the tear (14) so as not to interfere with healing of the tear (14). The fastener (18) can have a blind bore (24) opening through the head (22) of the fastener (18) and extending through the shank (20) to a location close to the tip (21) and generally radial holes (26) communicating between the bore (24) and the exterior of the shank (20). The medical adhesive can be injected through the bore (24) for passage outward through the holes (26).
摘要:
Methods, systems and devices for increasing the reliability of solid state drives containing one or more NAND flash memory arrays. The methods, systems and devices take into account usage patterns that can be employed to initiate proactive scrubbing on demand, wherein the demand is automatically generated by a risk index that can be based on one or more of various factors that typically contribute to loss of data retention in NAND flash memory devices.

A method of displaying an image with a display system includes receiving image data for the image. The method includes generating a first sub-frame and a second sub-frame corresponding to the image data based on a geometric relationship between a hypothetical reference projector and each of a first and a second projector. The method includes projecting the first sub-frame with the first projector onto a target surface. The method includes projecting the second sub-frame with the second projector onto the target surface, wherein the first and the second sub-frames at least partially overlap on the target surface.
摘要:
Tools for directing a collection of light emitting devices toward pixel locations to make an image are disclosed. A pixel location is a light emitting device target at least twice during a given frame, and each light emitting device in the collection is directed toward at least two different pixel locations during the frame. Adjacent light emitting devices may be directed toward adjacent pixel locations or toward nonadjacent pixel locations.
