Publication number: 20180188196Abstract: A multi-component fluid composition and concentration sensor system and method. The system can be configured with multiple sensing elements whereby each specifically responds to different combinations and concentrations of multiple fluid component mixtures. Because these responses can be captured and committed to a lookup table during an initial calibration sequence, subsequent measurements of unknown mixtures of the same gases will match known states found in the lookup table and the fluid concentrations can be deduced. The number of sensing elements with unique responses to the fluid mixtures should equal the number of unknown fluids that are active on the sensing surfaces, similar to how solving for multiple variables requires no fewer equations than there are unknowns, i.e. “3 equations and 3 variables.Type: ApplicationFiled: June 16, 2016Publication date: July 5, 2018Applicant: Multicore Photonics, Inc.Inventors: Christian Adams, Darren T. Engle, Robert S. Ryan, Jody W. Wilson

Patent number: 7428753Abstract: A system and method to ensure that a remote computer making a VPN connection complies with network security policies. Server driven security checks may be configured to verify compliance with each access level before access is granted at that level. The security checks may be selected based at least according to the information received from the remote computer. After the server determines that the remote computer complies with the security policy for the requested access level, the server may pass a token to the remote computer, or may grant VPN access to the remote computer. If the remote computer does not comply with the security policy associated with the requested access level but is in compliance with a security policy corresponding to a lower access level, the server may grant the remote computer access to the lower access level.Type: GrantFiled: September 6, 2006Date of Patent: September 23, 2008Assignee: Lehman Brothers Inc.Inventors: Michael T. Engle, Frederick Nwokobia, Bradley D. Noack, Jerzy Makowiecki
