  • Publication number: 20180328301
    Abstract: A control apparatus includes a first controller configured to generate control signals for controlling an engine or other machine, a second controller configured to generate the control signals for controlling the machine, a transfer circuit, and an arbiter circuit. The transfer circuit is coupled between the machine and the controllers, and is configured to switch from a first state, where the transfer circuit passes the control signals from the first controller to the machine, to a second state, where the transfer circuit passes the control signals from the second controller to the machine, responsive to receiving a first failure signal from the first controller. The arbiter circuit includes three (or more) arbiters, and is configured to control the transfer circuit from the first state to the second state responsive to any two of the three arbiters generating second signals indicative of failure of the first controller.

  • Patent number: 9475564
    Abstract: A method of determining fuel limits for an engine includes measuring an actual fuel value for the engine and creating a plurality of engine speed points. The method further includes calculating respective static fuel limit points for each of the engine speed points utilizing the actual fuel value. The static fuel limit points define and limit a rated power of the engine.

  • Publication number: 20160201591
    Abstract: A system is provided that includes one or more sensors configured to monitor operating parameters of engine components and a controller. The controller is programmed to perform operations that include displaying test details on a display screen that are specific to a selected test to be performed on the engine components. The test details include pre-conditional parameters of the engine components that are necessary prior to starting the selected test. The operations also include receiving the monitored operating parameters of the engine components from the one or more sensors and determining whether the monitored operating parameters satisfy the pre-conditional parameters. The operations further include, responsive to receiving an indication to start the selected test and determining that the measured operating parameters satisfy the pre-conditional parameters, performing the selected test on the engine components.

  • Patent number: 6954792
    Abstract: A system and method for providing pluggable authentication and access control in computer systems and services are described. The authentication and access control process may be categorized into three components: an authentication protocol, a user repository and an access control model. In one embodiment, the authentication and access control mechanism may be implemented as three pluggable modules: an authentication protocol handler module for the authenticator side, an authentication protocol handler for the side to be authenticated, and an access control context module on the authenticator side. The pluggable modules may be exchangeable to support a variety of authentication types, user repositories, and access control models. The authentication protocol handlers provide symmetrical methods to handle requests and responses in the authentication process that reflect the symmetrical nature of the authentication process.

  • Patent number: 6175364
    Abstract: Methods, software and data structures for installing a component in a container suitable for display on a display screen as part of a graphical user interface are disclosed. In one embodiment, a name and desired location for a component are provided. Both the desired component and a component object table that is to be associated with the component are then created. The component object table is arranged to identify both the location and identity of the component. The component object table is then referenced in a container lookup table arranged to associate the component object table with a container at the desired location. In a preferred embodiment, the container is a sliding panel associated with a window suitable for display on the monitor. The sliding panel is capable of supporting a plurality of handles that act as independent sub-containers.

  • Patent number: 6085228
    Abstract: A system allows an administrator to edit, from a client, property files that reside on a server. The client issues a request to the server for property information for an application program. After receiving the property information, the client passes it to a configuration portion of the application program, where the property information is edited by the administrator. The client receives the edited property information and sends it to the server, where it is stored.
