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.

Techniques are described herein that are capable of selectively scanning objects for infection by malware (i.e., to determine whether one or more of the objects are infected by malware). For instance, metadata that is associated with the objects may be reviewed to determine whether update(s) have been made with regard to the objects since a determination was made that the objects were not infected by malware. An update may involve increasing a number of the objects, modifying one of the objects, etc. Objects that have been updated (e.g., added and/or modified) since the determination may be scanned. Objects that have not been updated since the determination need not necessarily be scanned. For instance, an allowance may be made to perform operations with respect to the objects that have not been updated since the determination without first scanning the objects for infection by malware.

In one embodiment of the invention, a memory system includes non-volatile-memory-devices (NVMDs) coupled to memory channels to share busses and a memory controller coupled to the memory channels in communication between the plurality of NVMDs. Each NVMD independently executes a read, write, or erase operation at a time. The memory controller includes channel schedulers to schedule control and data transfers associated with the read, write, and erase operations on the memory channels; and high priority and low priority queues coupled to the channel schedulers. The channel schedulers prioritize operations waiting in the high priority queues over operations waiting in the low priority queues. The channel schedulers further prioritize read operations waiting in either the high priority queue or the low priority queue over write and erase operations waiting in each respective queue.

Techniques that enable a user or customer at a system site to review and, if desired, modify data identified at the system site for transmission to a diagnosis site prior to the transmission. The identified diagnostic data may be modified such that data that the user does not want to be sent to the diagnosis site (e.g., sensitive data) is excluded from the data communicated to the diagnosis site. The data may be modified by removing or excluding the sensitive data from the data that is communicated to the diagnosis site or replacing the sensitive data with non-sensitive data. The modified data may then be communicated from the system site to the diagnosis site in the form of a package.

A method for improving train performance, the method including determining a rail car parameter for at least one rail car to be included in a train, and creating a train trip plan based on the rail car parameter in accordance with one or more operational criteria for the train.

Methods and systems are provided for an engine. A condition of the engine may be diagnosed based on a combustion torque profile of the engine estimated using signals from a generator operationally connected to the engine and/or other signals associated with the engine. Different types of degradation may be distinguished based on discerning characteristics within the estimated combustion torque profile data. Thus, a degraded engine component may be identified in a manner that reduces service induced delay.

The present invention provides a mobile device cradle for a vehicle. The cradle may include docking members for receiving a mobile device of a driver of the vehicle. The cradle may also include a face recognition means for periodically capturing a face of the driver, environmental conditions, and traffic conditions. Further, the cradle may include an authentication unit for authenticating the mobile device and the face of the driver captured by the face recognition means and for providing an authentication signal for starting the vehicle to an electronic engine control unit (EECU). Furthermore, the cradle may include an information collection unit for collecting dynamic information associated with the driver and the vehicle from monitoring units. Moreover, the cradle may also include a communication unit for communicating the dynamic information to back office system(s) communicatively coupled to the mobile device via a wireless communication network.

摘要:
An infrastructure is provided for gathering diagnostic data that is relevant to an error or other conditions detected in a monitored system. A diagnosability framework is provided that automates the gathering of relevant diagnostic data upon occurrence of the condition in the monitored system. In one embodiment, context data is determined for the condition detected in the monitored system. A rule-based engine is provided that is configured to automatically determine one or more actions to be performed for the condition detected in the monitored system based on the determined context data. The actions may include performing tasks that gather diagnostic data that is relevant to the detected condition, store the gathered diagnostic data in a repository, recommend one or more diagnostic actions to a user, and other diagnostic related actions.

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.
