  • Patent number: 7139690
    Abstract: Object level conflict detection is provided. In an optimistic concurrency embodiment, when an object is to be updated, the database system is checked to determine whether any data related to fields of the object have changed since the object was read. This can be accomplished by storing a copy of the data when the initial object read function is performed and subsequently comparing the initial copy with the database data as it stands when the update is to be performed.

In an exemplary embodiment, sensor values from an actual engine plant are input to an engine component quality estimator which generates performance estimates of major rotating components. Estimated performance differences are generating by comparing the generated performance estimates to a nominal quality engine. The estimated performance differences, which are indicative of component quality, are continuously updated and input to a real-time model of the engine. The model receives operating conditional data and the quality estimates are used to adjust the nominal values in the model to more closely match the model values to the actual plant. Outputs from the engine model are virtual parameters, such as stall margins, specific fuel consumption, and fan/compressor/turbine efficiencies.

A non-violation event filter determines whether the vehicle approaching the traffic signal is actually performing a non-violation action. Non-violation events may include a variety of actions performed by the vehicle, and are fully configurable to meet the needs and policies of various specific intersections and jurisdictions. When the non-violation event filter determines that the vehicle is performing a non-violation action, it causes some number of resources that may have been allocated to recording the non-violating vehicle, and/or prevents further resources from being allocated to such recording.

  • Patent number: 6950788
    Abstract: A computer-implemented system and method for simulating the movement of motor vehicle and bicycle traffic in an environment. Among other things, the system and method scan all traffic signals in the environment over a predetermined time interval, and then update parking activity, pedestrian movement, and motor vehicle and bicycle movement in the environment. The system and method also check whether any parking activity was generated for the predetermined time period, and simulates pedestrian movement in the environment. Finally, the system and method simulate motor vehicle and bicycle movement in the environment using predetermined acceleration and deceleration rates, a motor vehicle following model, and a lane changing model.

  • Patent number: 6947881
    Abstract: A shared vehicle system includes a central facility, at least one vehicle distribution port facility and a plurality or fleet of vehicles, each having a vehicle subsystem. In general, the central station and port facility and the vehicle subsystems communicate in a manner to allow a user to enter information at a port facility. That information is then communicated to the central facility, where the information is processed to select a vehicle from the fleet to allocate to the user at the port facility. Selection of a vehicle for allocation to a user may be based on selecting an available or soon to be available vehicle according to various algorithms that take into account the vehicles state of charge.

  • Patent number: 6947875
    Abstract: A system for developing a design of an environment such as an aircraft cockpit. A processor generates body models describing a percentage of a body population potentially to be accommodated by the environment. A processor-user interface displays an environment design relative to the body models. The interface accepts user changes to the design and the body models. The processor modifies the design and the body models in accordance with user changes. The system allows a designer of an airplane cockpit to rapidly visualize, analyze and assess its accommodation of a desired percentage of pilots.

  • Patent number: 6944580
    Abstract: A method for designing an engine case static structure of a gas turbine engine includes creating signals representing an engine case static structure knowledge base of information. The knowledge base has a plurality of design rule signals with respect to a corresponding plurality of parameter signals of associated elements of an engine case static structure, wherein the knowledge base comprises at least one data value signal for each of the plurality of design rule signals. A desired data value signal is entered for a selected one of the plurality of parameter signals of an associated element of the engine case static structure and compared to the corresponding data value signal in the knowledge base for the corresponding one of the plurality of design rule signals. Signals representative of a geometric representation of the selected parameter signal may be created.

  • Patent number: 6941249
    Abstract: A computerized method of virtual flowbench simulation of fluid flow interaction with an object described in at least one design file includes receiving user-defined input via a user interface, the user-defined input including a specification of the at least one design file, accessing the at least one design file, and accessing a generic template describing basic geometries of the object, and modifying the basic geometries of the object with the at least one design file. Automatically, surface and volume mesh are generated in the object, and fluid flow interaction with the object is simulated. Predetermined data parameters are measured and stored during simulation. The method automatically checks the predetermined data parameter measurements to determine whether steady state has been reached and whether a predetermined maximum number of time steps has been reached.

  • Patent number: 6937968
    Abstract: A system and method for orbital planning allows iterative calculations of orbital parameters to be accomplished in an automated way with one parameter solution serving as input to the next parameter's calculation. A software program employs a graphical user interface (GUI) to allow a space mission analyst to set up a series of sub-problems of any desired level of complexity. The program then implements the series automatically and sequentially, incorporating the solution to one sub-problem into the input to the next.

  • Patent number: 6931368
    Abstract: A flight control display shows a representation of terrain, the horizon, an aircraft with a fuselage and aircraft wings, and a gamma ladder. The observer has a viewing direction at least in a predefined attitude range, which viewing direction is directed along the momentary flight path. The aircraft is therefore rotated depending on its momentary angle of incidence and angle of yaw with respect to the observer's viewing direction. The representation of the terrain is obtained from the relative position of a geodetic system of coordinates XG, YG, ZG and an aerodynamic system of axes of the airplane, in which case a reference line of the gamma ladder coincides with the horizon.
