Patent number: 11947884Abstract: An industrial CAD system is supplemented with features that allow a developer to easily convert a mechanical CAD model of an automation system to a dynamic digital twin capable of simulation within a simulation platform, including simulation of fluid dynamics throughout the system. The features allow the user to label selected elements of a mechanical CAD drawing with “aspects” within the CAD environment, and to add fluid models representing fluids that travel through or are processed by the system. Based on these aspect labels and fluid models, the CAD platform transforms the mechanical CAD model into a dynamic digital twin that can be exported to a simulation and testing platform to facilitate simulation of both machine operation and fluid dynamics.Type: GrantFiled: December 22, 2022Date of Patent: April 2, 2024Assignee: Rockwell Automation Technologies, Inc.Inventors: Ian McGregor, David Dawkins, Adam Davidson

Patent number: 11775749Abstract: The embodiments present a new class of content masking defenses against the Portable Document Format (PDF) standard. The defenses can identify attacks that cause documents to appear different than the underlying content extracted from the documents. A content masking defense method can include identifying a content masking attack by scanning a document file to extract a character code of a character appearing in the file. Next, the character is rendered based on a font that is embedded in the document file. Optical character recognition can be performed on the rendering, and a content masking attack can be identified based on a comparison of a result of the optical character recognition against the character code of the character.Type: GrantFiled: December 29, 2020Date of Patent: October 3, 2023Assignee: UNIVERSITY OF SOUTH FLORIDAInventors: Yao Liu, Zhuo Lu, Ian Davidson Markwood, Dakun Shen

Patent number: 10878186Abstract: The embodiments present a new class of content masking attacks against the Portable Document Format (PDF) standard. The attacks cause documents to appear different than the underlying content extracted from the documents by information-based services. The first attack allows academic paper writers and reviewers to collude via subverting the automatic reviewer assignment systems in current use by academic conferences. The second attack renders plagiarism detection software ineffective, targeting specific small plagiarism similarity scores to appear natural and evade detection. The final attack places masked content into the indexes for various search engines, which renders as information entirely different from the keywords used to locate it. The final attack enables spam, profane, or possibly illegal content to go unnoticed by these search engines but still be returned in search results.Type: GrantFiled: September 18, 2018Date of Patent: December 29, 2020Assignee: University of South FloridaInventors: Yao Liu, Zhuo Lu, Ian Davidson Markwood, Dakun Shen

Publication number: 20200200942Abstract: A downhole logging tool includes a tool body housing an opto-electronics assembly. The opto-electronics assembly includes a circuit board and an opto-electronics module coupled to the circuit board and receiving control signals from the circuit board. The opto-electronics module includes a light source, a reference detector, a measurement detector, and a first beam splitter positioned with respect to the light source and the reference detector. The first beam splitter directs a first portion of light emitted from the light source into the reference detector and a second portion of the light emitted from the light source into an optical conduit. The opto-electronics module also includes a second beam splitter positioned with respect to the optical conduit and the measurement detector. The second beam splitter directs at least a portion of light received from the optical conduit into the measurement detector.Type: ApplicationFiled: December 19, 2019Publication date: June 25, 2020Applicant: Baker Hughes Oilfield Operations LLCInventors: Andrew Main, Stephen Day, Ian Davidson, James David Ratcliffe
