Abstract: A vehicle monitoring device includes a camera or other optical sensor configured to be disposed at a trailing end of a first vehicle system. The camera or other optical sensor is configured to output one or more images or video of a field of view behind the first vehicle system. The monitoring device also includes a controller configured to receive output from one or more sensors and to activate the camera or other optical sensor to output the one or more images or video based on the output from the one or more sensors. The output from the one or more sensors indicates one or more of a change in movement of the first vehicle system, a temperature, an acoustic sound, or movement of a second vehicle system.

Abstract: A system and a method include an onboard communication system configured to be disposed onboard a vehicle system and comprising one or more processors. The one or more processors may generate a session key that includes a shared secret key that is known by the onboard communication system and an off-board communication system, generate one or more encryption keys by hashing the session key with an identifier based on a cycle time that is known by the onboard communication system and the off-board communication system, generate one or more encrypted messages by encrypting one or more messages associated with one or more of the vehicle system or a route over which the vehicle system moves based on the one or more encryption keys, and communicate the one or more encrypted messages from the onboard communication system to the off-board communication system.

Abstract: A vehicle control system receives a proximity signal at a sensor assembly from a vehicle system. The proximity signal indicates that the vehicle system is approaching a location of the sensor assembly. A sensor of the sensor assembly is activated responsive to receiving the proximity signal. One or more characteristics of the vehicle system are sensed as the vehicle system moves by the sensor assembly. A sensor signal that represents the one or more characteristics of the vehicle system is communicated to an onboard controller of the vehicle system and/or an off-board system to control operation of the vehicle system based on the one or more characteristics of the vehicle system.

Abstract: A system and method determine that a vehicle system is beginning rearward movement based on one or more characteristics of the vehicle system that are monitored by a movement sensor. A warning device is controlled to sound a notification to one or more locations off-board the vehicle system. The warning device is prevented from controlling the warning device to generate the notification while the vehicle system is moving in a direction other than the rearward movement. The warning device is permitted to generate the notification responsive to determining that the vehicle system is beginning the rearward movement.

Abstract: A system may include a controller with one or more processors. The controller may determine the wheel size of a wheel of a vehicle during a trip. The one or more processors may communicate a message associated with the wheel size to an off-board device when the wheel size is below a threshold size.

Abstract: A computer implemented method, apparatus, and computer usable program code for updating multiple concurrent versions of shared artifact libraries. Shared artifact libraries are associated with a consuming application for establishing shared artifact libraries upon which the consuming application has a dependency for artifacts. A snapshot of the shared artifact libraries associated with the consuming application in an active session is created in response to starting a session. The shared artifact libraries are updated in response to new versions and updates of the shared artifact libraries becoming available. Artifacts are dispensed from the shared artifact libraries to the consuming application based on the snapshot of the session.

Abstract: When a data object is sent from one application to another, the marshaling code includes type information with transmission of the data object. When the data object is converted to the transmission format, type information for the data object is added to the transmission format element. The unmarshaling code uses the type information to obtain schema information for converting the transmission format element back to the data element.

Abstract: A mechanism is provided for converting after image data into a delta level change. An after image business graph is first transformed into a generic after image business graph. Another transformation is performed transforming the generic after image business graph into a second after image business graph, using delta information from another enterprise information system is used to create a delta business graph. A final transformation is performed to convert the delta business graph into a generic delta business graph.

Abstract: A method, system, and computer usable code is provided for using a templated pattern to define part types on a web service definition language (WSDL) interface. Applying the templated pattern enables peer services to define a transparent contract between specific WSDL part types. The templated pattern is used to wrap the original business object with the enriched business graph schema. The templated business graph is created by extending the business graph complex type that is provided by the business object framework runtime and adding an element delegating to the original business object.

Abstract: A method in a data processing system for a generic symbol referencing mechanism. A reference to a symbol is received for resolution. The symbol is identified using a data structure. The data structure comprises a set of symbol space instances, each symbol space instance contains a set of name space registry instances, each name space registry instance contains a set of name space instances, each name space instance contains a set of name instances, each name instance corresponds to a referencable symbol instance, and the referencable symbol instance corresponds to the symbol.

Abstract: Schema information is provided with transmission of a data object. When a data object is converted to a transmission format, schema information for the object type is added to the transmission format element. The unmarshaling code uses the schema information to update a schema registry at the receiving end. The schema registry may then be used as a tool for converting the transmission format element back to the data element. The next time an object of that object type is sent to the recipient, the schema information is not added to the transmission format element.

Abstract: A method, apparatus, and computer usable code for locating artifacts. A query is received from a client to locate an artifact, wherein the request includes a set of criteria for the artifact. A request is sent to a set of locators based on the set of criteria in the request in response to receiving the request, and a reply is returned to the client, wherein the reply includes a pointer to the artifact in response to receiving a positive response from the set of locators.

Abstract: An apparatus, system, and method are disclosed for facilitating dynamic modification of existing software objects defined in a strongly-typed programming language. The apparatus includes an invocation framework, an embedder, a reference component, and a development reference component. The invocation framework is configured to pass a loosely-typed base object between a source component and a destination component. The embedder embeds a business object within the base object. The business object is defined at least in part by a type definition having a set of attributes and a name value uniquely associating the type definition to the business object. The reference component references the base object such that typing requirements of the business object are not explicitly enforced in a runtime environment. The development reference component references the type definition within a development environment such that typing for the business object is fixed during source code development and deployment.
