Patent number: 9805281Abstract: An apparatus and method for processing a captured image and, more particularly, for processing a captured image comprising a document. In one embodiment, an apparatus comprising a camera to capture documents is described. In another embodiment, a method for processing a captured image that includes a document comprises the steps of distinguishing an imaged document from its background, adjusting the captured image to reduce distortions created from use of a camera and properly orienting the document is described.Type: GrantFiled: June 8, 2015Date of Patent: October 31, 2017Assignee: COMPULINK MANAGEMENT CENTER, INC.Inventors: Minghui Wu, Rongfeng Li, Wenxin Li, Edward P.

Patent number: 8852078Abstract: The present invention provides a practical, non-invasive, and efficient method for cryopreservation of an in-vitro-produced porcine embryo. The inventive method treats the NP (such as IVF- or NT-derived) embryo at the one-cell or cleavage stage prior to compaction with high osmolality followed by high speed centrifugation. The high osmolality treatment enlarges the periviteline space, and with centrifugation, enables the separation of the lipids from the cytoplasm. The lipid-separated embryos after high osmolality treatment have been successfully cryopreserved and later recovered and transferred to produce live offspring.Type: GrantFiled: August 28, 2009Date of Patent: October 7, 2014Assignee: The Curators of the University of MissouriInventors: Randall S. Prather, Rongfeng Li, Clifton N. Murphy, Lee Spate
