  • Patent number: 7980183
    Abstract: A railroad locomotive includes a naturally-aspirated reciprocating internal combustion engine, and a traction generator driven by the engine. A throttle position sensor produces a signal corresponding to the throttle position selected by the locomotive's operator. A load regulator receives a speed signal derived from the throttle position signal and outputs an excitation signal for the traction generator which is modified by a controller in response to air availability so that engine speed and load are controlled independently of the selected throttle position, so as to limit the exhaust smoke output of the engine.

  • Patent number: 7941707
    Abstract: Techniques for gathering information during runtime of a monitored system such that the information is available for facilitating diagnostics for the monitored system. In one embodiment, upon detection of a condition (such as an error condition) in the monitored system, a portion of the gathered information provides contextual information that facilitates gathering of diagnostic data that is relevant for the detected condition. This facilitates capturing of diagnostic data that is relevant for diagnosing the detected condition. The information gathered and stored during runtime may include information related to local variables, information related to tagged information (e.g., tagged functions/processes) executing in the monitored system, information related to potential impacts to the monitored system due to failures, metadata information, and other information.

  • Patent number: 7937623
    Abstract: A diagnosability system for automatically collecting, storing, communicating, and analyzing diagnostic data for one or more monitored systems. The diagnosability system comprises several components configured for the collection, storage, communication, and analysis of diagnostic data for a condition detected in monitored system. The diagnosability system enables targeted dumping of diagnostic data so that only diagnostic data that is relevant for diagnosing the condition detected in the monitored system is collected and stored. This in turn enables first failure analysis thereby reducing the time needed to resolve the condition detected in the monitored system.

  • Publication number: 20100242094
    Abstract: Methods, systems, and computer-readable media are disclosed for identifying telemetry data. A particular method scans a file and compares the file to at least one attribute to be used for telemetry collection. When the file is identified as a telemetry candidate, an offer to submit a sample of the file is sent to a server. A response to the offer is received from the server. If the response to the offer indicates an acceptance, a sample of the file is sent to the server.

  • Publication number: 20100211780
    Abstract: Apparatus, systems, and methods may operate to establish a secure communications tunnel between a server node and a client node, and to receive user requests from the client node at the server node via the secure communications tunnel. The user requests may be received in conjunction with a device verification token derived from nonces generated by the server node and transmitted to the client node as part of keep-alive response messages. The nonces may change according to a period of time established by the server node. Additional apparatus, systems, and methods are disclosed.

  • Publication number: 20100058132
    Abstract: A method and apparatus for power control of the re-transmission data packet in a wireless communication system is disclosed. A first wireless communication device is provided that receives (210) a data packet from a second wireless communication device and determines (220) if the data packet is correctly decoded. If the data packet is not correctly decoded, the first wireless communication device calculates (230) a first re-transmission power required for correctly decoding the data packet based on a signal to noise ratio (Eb/No) versus frame error rate (FER) relationship. And further calculates a power difference (240) between the calculated re-transmission power and the power of the received data packet and transmits the power difference (250) to the second wireless communication device. The second wireless communication device calculates (340) a second re-transmission power based on the received power difference and re-transmits (350) the data packet at the calculated re-transmission power.

  • Publication number: 20090105982
    Abstract: Techniques for controlling collection of diagnostic data in a monitored system. A set of flood control rules are configured for the monitored system for controlling the gathering of diagnostic data in the monitored system. The set of flood control rules may include one or more default flood control rules. The set of flood control rules are user-configurable enabling the user of the monitored system to set policies for dynamically controlling gathering of diagnostic data for the monitored system. In one embodiment, diagnostic data gathering is controlled based upon a number of previous occurrences of a condition in some predefined or user-configured time frame that triggers diagnostic data gathering and/or a number of previous executions of an action performed in some predefined or user-configured time frame responsive to the condition in the monitored system.
