Patent number: 11933932Abstract: This invention is useful for determining the permeability of a geological formation using 1H NMR diffusion measurements acquired in the laboratory and using downhole 1H NMR well logging. The current technology for obtaining formation permeability downhole using NMR is not adequate for low-permeability, unconventional source rock formations with high organic content. This new method uses laboratory 1H NMR diffusion measurements for creating continuous downhole well logs of the mobile-hydrocarbon permeability of the hydrocarbon-filled pore space of downhole geological formations.Type: GrantFiled: April 6, 2021Date of Patent: March 19, 2024Assignee: VINEGAR TECHNOLOGIES LLCInventors: Harold J. Vinegar, Philip M. Singer, George J. Hirasaki, Zeliang Chen, Xinglin Wang, Eva Vinegar

Patent number: 11921069Abstract: The following invention is used for determining the relative permeability of a fluid in a rock for three different phases: water, oil, and gas, in both conventional and unconventional formations. The permeability of a phase describes how much it can flow in porous media given a pressure gradient and is useful in evaluating reservoir quality and productivity. The following invention is a method to determine the three-phase relative permeabilities in both conventional and unconventional formations using NMR restricted diffusion measurements on core with NMR-active nuclei, combined with centrifugation of the core. In addition, the tortuosity, pore size (surface-to-volume ratio), fluid-filled porosity, and permeability is determined for each of the three phases in a rock.Type: GrantFiled: April 6, 2021Date of Patent: March 5, 2024Assignee: Vinegar Technologies LLCInventors: Eva Vinegar, Philip M. Singer, George J. Hirasaki, Zeliang Chen, Xinglin Wang, Harold J. Vinegar

Patent number: 7640434Abstract: A system identifies undesirable content in responses sent to a user, such as in e-mail or in downloadable files, from an Internet or intranet site. The system utilizes a redirection program that identifies content requests from a user to a target server. The redirection program redirects the request to a proxy server that sends the request to the target server. Upon receipt of the response from the target server, the proxy server scans the response, which includes any attachments, for undesirable content, such as junk e-mails, computer viruses, pornographic material, and/or other undesirable content. The proxy server then acts upon the response, and any undesirable content, in accordance with default or user-defined parameters, such as removal of the undesirable content. The proxy server may then send the response, as modified, or a notification message to the redirection program forwarding to the user.Type: GrantFiled: January 11, 2002Date of Patent: December 29, 2009Assignee: Trend Micro, Inc.Inventors: Frank Lee, Jeremy G.

Patent number: 7496960Abstract: An apparatus and method for providing real-time tracking of virus information as reported from various computers on a distributed computer network. Each client computer on the distributed network contacts an anti-virus scanning site. The site provides a small program or applet that resides in temporary memory of the client computer. The client-user invokes the scan with supplied pattern updates for detecting recent viruses. When the scan has been completed, the user is prompted to supply a country of origin. The name of the virus, its frequency of occurrence, and the country are forwarded as a virus scan log to a virus tracking server, which receives the virus information and thereafter stores it in a database server, which is used to further calculate virus trace display information. A tracking user contacts the virus tracking server and receives map information, which traces the virus activity.Type: GrantFiled: October 30, 2000Date of Patent: February 24, 2009Assignee: Trend Micro, Inc.Inventors: Eva Chen, Jimmy Sun, Terrence Chou, Steven Deutsch, Mark Havran

Patent number: 6119165Abstract: In an Internet or Intranet environment, a proxy server (or router or intelligent switch or firewall) which supports a number of clients (e.g. web browsers) has additional functionality which allows it to deliver a software module to a particular client depending on characteristics of that client. This downloaded module is then executed by the client which sets up a bidirectional communications link between the proxy server and the client. This bidirectional link allows for instance a status display at the client, by use of a window on the client platform, indicating the current status of proxy server activity such as virus scanning, content filtering, bandwidth usage, etc. In other applications the downloaded module allows provision of a organizational bulletin board, news channel, or provider of common software patches.Type: GrantFiled: November 17, 1997Date of Patent: September 12, 2000Assignee: Trend Micro, Inc.Inventors: Bobby Li, Eva Chen

Patent number: 5960170Abstract: The iterative detection and treatment of viruses using virus detection objects and virus treatment objects is disclosed. Pursuant to a request for a virus scan, a virus detection object is produced by a server and is transmitted to a client for execution. The client receives and executes the virus detection object, and the results are transmitted to the server. The server uses the results to produce an additional virus detection object which is also transmitted to the client and executed so that the results can be transmitted to the server. The iterative production and execution of virus detection objects is continued until a determination is made as to whether the targeted file or data includes a virus. Upon a determination that a targeted file or data includes a virus, a vaccine specifically tailored to the conditions presented at the client and the type of virus detected is produced, preferably in the form of a virus treatment object.Type: GrantFiled: March 18, 1997Date of Patent: September 28, 1999Assignee: Trend Micro, Inc.Inventors: Eva Chen, Steven Yuen-Lam Lau, Yung-Chang Liang

Patent number: 5889943Abstract: The detection and elimination of viruses on a computer network is disclosed. An apparatus for detecting and eliminating viruses which may be introduced by messages sent through a postal node of a network electronic mail system includes polling and retrieval modules in communication with the postal node to determine the presence of unscanned messages and to download data associated with them to a node for treatment by a virus analysis and treatment module. A method for detecting and eliminating viruses introduced by an electronic mail system includes polling the postal node for unscanned messages, downloading the messages into a memory of a node, and performing virus detection and analysis at the node.Type: GrantFiled: March 29, 1996Date of Patent: March 30, 1999Assignee: Trend Micro IncorporatedInventors: Shuang Ji, Eva Chen, Yung-Chang Liang, Warren Tsai

Patent number: 5623600Abstract: A system for detecting and eliminating viruses on a computer network includes a File Transfer Protocol (FTP) proxy server, for controlling the transfer of files and a Simple Mail Transfer Protocol (SMTP) proxy server for controlling the transfer of mail messages through the system. The FTP proxy server and SMTP proxy server run concurrently with the normal operation of the system and operate in a manner such that viruses transmitted to or from the network in files and messages are detected before transfer into or from the system. The FTP proxy server and SMTP proxy server scan all incoming and outgoing files and messages, respectively before transfer for viruses and then transfer the files and messages, only if they do not contain any viruses.Type: GrantFiled: September 26, 1995Date of Patent: April 22, 1997Assignee: Trend Micro, IncorporatedInventors: Shuang Ji, Eva Chen
