Patent number: 8990023Abstract: An automated cell injection system and method are described, which can perform automatic, reliable, and high-throughput cell injection of foreign genetic materials, proteins, and other compounds. The system and method overcome the problems inherent in traditional manual injection that is characterized by poor reproducibility, human fatigue, and low throughput. The present invention is particularly suited for zebrafish embryo injection but can be readily extended to other biological injection applications such as mouse embryo, drosophila embryo, and C. elegans injections, capable of facilitating high-throughput genetic research at both academic and industry levels. A novel vacuum based cell-holding device is also provided.Type: GrantFiled: February 25, 2007Date of Patent: March 24, 2015Inventors: Yu Sun, Wenhui Wang, Xinyu Liu

Publication number: 20120116255Abstract: An optical fiber sensor (100) can be used to measure pressure with high sensitivity and fine resolution. As a (108) at the end of the sensor expands or contracts, the spectrum of a beam reflected from the end of fiber shifts, producing a change linked to pressure exerted on the sensor. Novel aspects of the present inventive sensor include the direct bonding of a silica thin film diaphragm (110) to the optical fiber with localized or confined heating and a uniform thickness of the diaphragm. The resulting sensor has a diameter that matches the diameter of the optical fiber. Because the sensor is all silica, it does not from temperature-induced error. In addition, the sensor can be very sensitive because the diaphragm can be very thin; it can also make highly repeatable measurements due to its very uniform thickness.Type: ApplicationFiled: June 29, 2010Publication date: May 10, 2012Inventors: Wenhui Wang, Xingwei Vivian Wang, Kai Sun, Nan Wu

Publication number: 20100036691Abstract: A software project management method uses templates from one project phase as inputs to their subsequent project phases. The project is organized in four phases, each phase having one or more steps and one or more attributes. Using XSL, a phase model is transformed into a starting point as input for the subsequent phase model. XSL-FO is used to generate PDF documents from any phase model to export a particular project deliverable. The information and data created within that phase still has meaning as input for the next phase. A model thus derived can be reused for another project as well as to transform into a model used by a subsequent phase within the same project.Type: ApplicationFiled: August 6, 2008Publication date: February 11, 2010Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: RICHARD BRADLEY BOULDIN, TAL FRIEDMAN, MICHAEL DOUGLAS JAMES SHIELDS, WENHUI WANG, KIRK WENDLAND
