Abstract: A method and device for ascertaining movement authority for track-bound vehicles allow interference with a driving operation resulting in special operational situations or disturbances to be kept as low as possible. The position of the vehicle is determined and used to check whether the vehicle is located completely in an axle-counting section of an axle-counting system. The number of axles of the vehicle is compared with the number of axles located in the relevant section according to the system. If the vehicle is located completely in the relevant section and the number of axles of the vehicle matches the number of axles located in the section according to the system, a movement authority is ascertained for the vehicle. The part of the relevant section in front of the vehicle in the driving direction is assumed to be free of other vehicles when ascertaining the movement authority.

Abstract: Methods related to communication between and within nodes in a high performance computing system are presented. Processing time for message exchange between a processing unit and a network controller interface in a node is reduced. Resources required to manage application state in the network interface controller are minimized. In the network interface controller, multiple contexts are multiplexed into one physical Direct Memory Access engine. Virtual to physical address translation in the network interface controller is accelerated by using a plurality of independent caches, with each level of the page table hierarchy cached in an independent cache. A memory management scheme for data structures distributed between the processing unit and the network controller interface is provided. The state required to implement end-to-end reliability is reduced by limiting the transmit sequence number space to the currently in-flight messages.

Abstract: A portable eye tracker device is disclosed which includes a frame, at least one optics holding member, and a control unit. The frame may be adapted for wearing by a user. The at least one optics holding member may include at least one illuminator configured to selectively illuminate at least a portion of at least one eye of the user, and at least one image sensor configured to capture image data representing images of at least a portion of at least one eye of the user. The control unit may be configured to control the at least one illuminator for the selective illumination of at least a portion of at least one eye of the user, and receive the image data from the at least one image sensor.

Abstract: A development system with methodology for run-time restoration of UML model from program code is described. In one embodiment, for example, in a computer system, an improved method is described for developing and executing an application, the method comprises steps of: creating a model describing business objects and rules of the application; creating source code for the application, including representing the model within the source code itself; compiling the source code into an executable application; running the executable application on a target computer in conjunction with a run-time framework that provides services to the executable application; and while the executable application is running, reconstructing the model from the executable application and making it available to the run-time framework.
