20100205608 | Mechanism for Managing Resource Locking in a Multi-Threaded Environment - A mechanism is disclosed for implementing resource locking in a massively multi-threaded environment. The mechanism receives from a stream a request to obtain a lock on a resource. In response, the mechanism determines whether the resource is currently locked. If so, the mechanism adds the stream to a wait list. At some point, based upon the wait list, the mechanism determines that it is the stream's turn to lock the resource; thus, the mechanism grants the stream a lock. In this manner, the mechanism enables the stream to reserve and to obtain a lock on the resource. By implementing locking in this way, a stream is able to submit only one lock request. When it is its turn to obtain a lock, the stream is granted that lock. This lock reservation methodology makes it possible to implement resource locking efficiently in a massively multi-threaded environment. | 08-12-2010 |

20080291391 | HYBRID CONTACT LENSES PREPARED WITH EXPANSION CONTROLLED POLYMERIC MATERIALS - A hybrid contact lens includes a substantially rigid center portion and a substantially flexible skirt portion connected to the center portion. The skirt portion is formed using xerogels compatible with diluents comprising at least one selected from polylactic acid, polyglycolic acid, lactide, glycolide, a polyacetal, a cyclic acetal, a polyketal, a cyclic ketal, a polyorthoester, a cyclic orthoester, di-t-butyl-dicarbonate, tris(trimethylsilyl)amine, and 2,2,2-trifluoroacetamide. These diluents are formulated to function as a stand-in for water in the xerogel polymer, allowing the xerogel to form and bond to the rigid center portion in its fully expanded state. Upon hydration of the hybrid lens, substantially little dimensional change, and thus substantially little distortion, is obtained in the skirt portion. The diluents of the present invention further preserve the mechanical integrity of the xerogel, allowing the xerogel to be machined to final shape, improving the dimensional tolerances which can be achieved in the hybrid lens. | 11-27-2008 |

20090028585 | Interactive visual card-selection process for mitigating light-area banding in a pagewide array - Preferably, test-patterns print on separate, multiple print-medium cards, each including a ramp with colors graded along a certain direction—and, superimposed on the ramp, a candidate add-on colorant. Ramps preferably are printed in so-called “customer colors”, common in snapshots and particularly snapshot regions that include sky. Positions or amounts of the candidate add-on colorant canvass a likely range of values that optimize camouflaging or suppression of a banding artifact (due to seams in the pagewide array) that is extended along the same certain direction. For each seam and each “customer color” used, an operator holds up several cards for comparison, selecting the best one to three. Operators thus can evaluate candidate colorant patterns in context of many different tones of the sky and other customer colors. Preferably banding suppression is integrated with linearization: at each seam a series of linearization tables is smoothly interpolated between measurement-based tables for adjacent inkjet dice. | 01-29-2009 |

20130006283 | FISTULA TREATMENT DEVICES AND RELATED METHODS - Disclosed herein are implantable fistula treatment devices and related methods. In some embodiments, a distal anchor for an implantable fistula treatment device may comprise a suture and a plurality of foldable members including at least a distal-most foldable member and a proximal-most foldable member. The distal-most foldable member may comprise a suture attachment structure. The distal-most foldable member may comprise a distal first average dimension substantially parallel to the longitudinal axis of the suture, a distal second average dimension orthogonal to the distal first average dimension, and a distal third average dimension orthogonal to the distal first and second average dimensions. The distal first average dimension may be no greater than 30% of the greater of the distal second and third average dimensions. The proximal-most foldable member may be configured to couple to a surface of a body lumen at a distal opening of a fistula. The proximal-most foldable member may also be configured to occlude the fistula at the distal opening and may also be configured to slide along the suture attached to the suture attachment structure. The proximal-most foldable member may comprise a proximal first average dimension substantially parallel to a longitudinal axis of the suture, a proximal second average dimension orthogonal to the proximal first average dimension, and a proximal third average dimension orthogonal to the proximal first and second average dimensions, where the proximal first average dimension may be no greater than 10% of the greater of the proximal second and third average dimensions. | 01-03-2013 |
