  • Publication number: 20180188196
    Abstract: 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.

  • Publication number: 20110027092
    Abstract: An arrangement for axial locking of rotating blades in a rotor is provided. The arrangement includes a shaft collar, a projection, plate-like sealing elements, and a blocking element. The sealing elements are provided for axially securing the rotating blades. At least one sealing element has an opening for securing the sealing elements against displacement in the circumferential direction. The blocking element is inserted in a recess from the end side of the shaft collar and blocks the displacement path of the sealing element. In order for the blocking element to be secured against unintentional releasing, the blocking element is fastened on the rotor disk using plastic deformation.

  • Patent number: 7520718
    Abstract: A seal plate system adapted to fit between axially adjacent turbine blades and turbine vanes is disclosed. The seal plate system may be formed from a plate adapted to position a turbine blade in a rotor assembly and lock the turbine blade into the rotor assembly. The plate may also function to seal a cooling system in the turbine blade. In at least one embodiment, the plate may be configured to accomplish both of these tasks together once installed into a mini disc of the rotor assembly.

  • Patent number: 7428753
    Abstract: 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.
