Patent number: 10379914Abstract: In accordance with an embodiment, described herein is a system and method for achieving specific behaviors by intercepting file access calls in a mainframe application rehosted in a mainframe rehosting platform. A custom file handler can include a custom version of each of a plurality of default file operation application program interfaces (APIs) available in the mainframe rehosting platform, and can be invoked by the rehosted mainframe application. Each custom file operation API can perform one of a plurality of specific behaviors comprising changing a file access mode, appending a specific data field at the end of each record or line of a file, and performing one or more special post-handling actions. If the rehosted mainframe application cannot detect the existence of a custom file handler, a file access call can be directed to one or more of the plurality of default file operations APIs.Type: GrantFiled: December 21, 2016Date of Patent: August 13, 2019Assignee: ORACLE INTERNATIONAL CORPORATIONInventors: Weixuan (Wade) Zhang, Zhaoyong Zhang, Wei (David) Pan

Publication number: 20180264179Abstract: An ocular implant is provided for an intraocular delivery of a therapeutic biologic agent. The implant may be used intracamerally or intravitreally. The implant may include a sustained-release biodegradable core and a biodegradable shell, wherein the shell has a longer biodegradable half-life than the core. The core may include a biodegradable gel medium, an active therapeutic biologic agent, and a biologic stabilizer. Upon insertion into the anterior chamber or vitreous body of an eye, the therapeutic biologic agent is released over an extended period, that may range from one day to one year. The therapeutic biologic agent may be, for example, tissue-plasminogen activator, an anti-VEGF agent, or another biopharmaceutical. The biodegradable implant may completely dissolve after implantation and need not be removed.Type: ApplicationFiled: March 19, 2018Publication date: September 20, 2018Inventors: David PAN, Brian W.

Publication number: 20070020004Abstract: Embodiments use an apparatus comprising a media path that is adapted to transport media sheets within the printing apparatus. Fuser rolls are positioned along the media path, and the fuser rolls are adapted to fuse marking material on the media sheets as the media sheets pass the fuser rolls. A heating belt is positioned to pass a first location between the fuser rolls and to pass a second location separate from the fuser rolls. A heater is positioned in the second location, and the heater is adapted to heat the heating belt. In addition, an iso-thermalizing roller is in contact with the heating belt. In some embodiments, the elements can be positioned in any order. In other embodiments, the elements are positioned such that the heating belt passes the elements in the following order: the heater, the fuser rolls, and then the iso-thermalizing roller.Type: ApplicationFiled: July 21, 2005Publication date: January 25, 2007Inventors: Gerald Domoto, Nicholas Kladias, David Pan

Publication number: 20060228639Abstract: Toners including a low melt wax and a carnauba wax are described. The toners include at least one binder, at least one colorant, at least one wax having a melting point of 135° C. or less, and a compatibilizer wax (e.g., carnauba wax). The low melt wax is preferably polyethylene wax. Images may be formed with the toners in an image forming process including steps of depositing the toner onto a latent image of an imaging member to form a toner image, transferring the toner image to an image receiving substrate, and fusing the toner image. During the fusing, the at least one wax and the compatibilizer wax exude from the toner, forming a stripping enhancing layer upon the toner image. Thus, fuser roll stripping performance is enhanced.Type: ApplicationFiled: April 12, 2005Publication date: October 12, 2006Applicant: Xerox CorporationInventors: Eugene Young, David Pan, Robert Pawlik, Robert Tuchrelo, Billy Stojanovski, William Hollenbaugh, Michael Grande, Hui Chang, Mark Mang

Patent number: 5981720Abstract: Isolation of the salivary basic glycoproteins CON-1 and CON-2 in high purity and without substantial loss of activity was achieved in a method utilizing two denaturing steps which limit proteolysis. Cloning of CON-1 and CON-2 from the PRB2 and PRB1 genes also provides a recombinant source of the proteins, which are useful inhibitors of alpha-glucosidases in the treatment of diabetes and in preventing retroviral infection. Subfragments of CON-1 and CON-2 having alpha-glucosidase inhibitory activity are identified which can be prepared synthetically in commercial-scale quantities.Type: GrantFiled: September 8, 1997Date of Patent: November 9, 1999Inventors: Edwin A.
