Patent number: 8612091Abstract: An analysis tool which extracts all the available parameter identifications (i.e. PIDS) from a vehicle's power train control module for diagnostic decisions. This is done by checking these PIDS and other information (e.g., calculated PIDS, Break Points, charts and algorithms) in three states; key on engine off, key on engine cranking, key on engine running. In all three modes the tool is comparing the live data from PIDS and voltage to the other information (e.g, Break Points). If any of this data are outside the programmed values a flag is assigned to the failure or control problem. The relationship between a particular PID and its associated preprogrammed value(s) may be indicated by a light. The depth of the problem (if any) is conveyed by the color of the light. Also included are tests/charts for fuel trim, engine volumetric efficiency, simulated injector, power, catalyst efficiency, and engine coolant range.Type: GrantFiled: April 16, 2012Date of Patent: December 17, 2013Inventors: Bernie C.

Patent number: 8589133Abstract: Interdependencies between pairs/groups of individual systems are evaluated in determining the composition of a universal system of interdependent systems. Data tables reflecting the interdependencies are contained in a central database resident in a server's memory.

Patent number: 8589131Abstract: This procedure proposes the appropriate equations that determine the rotor movement in order to obtain the aerodynamic actions for each blade in each iteration (the forces that are transmitted to the helicopter and the moments with respect to the articulations), and they are resolved by discretizations made in the rotor disc, such that that the blade elements of the partition are connected to the disc, which does not rotate, instead of to each blade. The blades pass through an azimuth range in each iteration, making a division of each blade longitudinally into ne elements, and the rotor disc into na sectors, corresponding to divisions of the range of azimuth angles. Therefore, partitions are made on ne·na blade elements, identifying each blade element by means of its distance to the rotor axis and its azimuth angle.Type: GrantFiled: August 16, 2007Date of Patent: November 19, 2013Assignee: Indra Sistemas, S.A.Inventor: Miguel Gonzalez Cuadrado

Patent number: 8489373Abstract: A method of computer simulation of an aerodynamic behavior of an aircraft in flight close to the ground includes generating a volume mesh of a three-dimensional geometric domain. The volume mesh is at least partly delimited by a three-dimensional geometric model of the aircraft and by a plane modelling the ground. The volume mesh defines a computational domain. The method also includes imposing a uniform boundary condition on the plane comprising a predetermined speed vector with a non-zero tangential component and a non-zero normal component, and solving a discrete numerical model of the Navier-Stokes equations by computer on the volume mesh with the uniform boundary condition imposed on the plane to obtain a numerical solution of a fluid flow inside said computational domain.Type: GrantFiled: April 13, 2010Date of Patent: July 16, 2013Assignee: Airbus Operations S.A.S.Inventor: Benoit Calmels

Patent number: 8484002Abstract: Systems and methods for, inter alia, geographically based analyses of traffic being carried over a wide scale traffic network. The systems integrate geographical information systems (GIS) with traffic simulation processes to allow a user to analyze traffic patterns and loads at specific geographic locations of regions. Additionally, these systems allow for traffic analysis over a wide scale traffic network that may encompass the traffic network that exists within a geographic region and can include, as examples, the traffic networks that span across a city, that interconnect cities, that interconnect states and that run across multiple states. To this end, the systems include traffic simulators that can adaptively or controllably select between multiple traffic simulation models for simulating traffic across different segments of the traffic network. The different models provide varying levels of granularity for measurements of geographical location of a vehicle traveling over the traffic network.Type: GrantFiled: December 21, 2006Date of Patent: July 9, 2013Assignee: Caliper CorporationInventors: Qi Yang, Howard Slavin, Kjarran Stefansson, Andres Rabinowicz, Simon Olsberg, Mary LaClair, Jonathan Brandon

Patent number: 8473266Abstract: In a method for simulating a physical property of a component model in the form of a computer accessible construction model of a technical structure, a mesh of a component model is automatically generated. The component model is first described by a fine mesh of finite elements, and, based on the fine mesh, the natural oscillation behavior of the component model is determined. Based on the natural oscillation behavior, at least one area of the component model is determined, whose finite elements are less deformed than those of another area of the component model. The determined area of the component model is then described by a coarser mesh of finite elements.Type: GrantFiled: September 15, 2009Date of Patent: June 25, 2013Assignee: Bayerische Motoren Werke AktiengesellschaftInventor: Christian Guist
