Abstract: In one example, a proxy server acts as a gateway to a website and modifies the traffic between a web browser on a user device and the website server, as necessary to request protection by providing step-up authentication and/or transaction verification. The proxy server blocks transactions when protection is required but has not occurred (either because the authentication was not proper or due to the detection of another problem). Associated methods and systems are also provided.

Abstract: A procedure for igniting a combustion chamber of a turbine engine, the chamber being fed with fuel by injectors and including an igniter mechanism igniting the fuel injected into the chamber. The procedure includes an initial stage during which fuel is injected into the chamber at a constant rate while simultaneously exciting the igniter mechanism, and in event of non-ignition of the chamber at an end of the initial stage, a second stage during which a rate at which fuel is injected is increased rapidly by 20% to 30%.

Abstract: A turbomachine combustion chamber in which a chamber end wall presents an opening for receiving a pre-vaporization bowl, and including a device for injecting air and fuel mounted on the axis thereof, the bowl being floatingly mounted relative to the chamber end wall to move in a predetermined radial direction and flaring downstream so as to form a collar, a deflector forming a thermal shield being made integrally with the bowl beside the chamber end wall so that the floating movement of the bowl-and-deflector assembly takes place in a sliding plane situated between the deflector and the chamber end wall.

Abstract: A method and apparatus for protecting communication of information through a graphical user interface displays a graphical user interface that includes a trusted interaction window. In one example, the method includes continuously determining whether information has been overlayed on top of at least a portion of the displayed trusted interaction window and then disabling an operation being requested when an overlay condition has been determined. In one example, the trusted interaction window is maintained to be the top most window when it is called by an application, for example, during an online transaction, or any other suitable action. The trusted interaction window may be generated via a browser, or operating system, or any other suitable application. As such, the trusted interaction window detects when another window is overlayed on top of it, such as a chromeless window, thereby preventing an unscrupulous party from tricking the user or obtaining sensitive information.
