Abstract: Systems, methods, and devices of the various embodiments provide a hardware and software architecture enabling electrochemical impedance spectroscopy (“EIS”) to be performed on multiple electrochemical devices, such as fuel cells, at the same time without human interaction with the electrochemical devices. In an embodiment, a matrix switch may connect each cell of a fuel cell stack individually to an EIS analyzer enabling EIS to be performed on any fuel cell in the fuel cell stack. In a further embodiment, the EIS analyzer may be a multi-channel EIS analyzer, and the combination of the matrix switch and multi-channel EIS analyzer may enable EIS to be performed on multiple fuel cells simultaneously.

Abstract: In a computer system running at least a first virtual machine (VM) and a second VM on virtualization software, a computer implemented method for the second VM to provide quasi-lockstep fault tolerance for the first VM. The method includes enabling operations of the second VM to diverge from being in lockstep with operations with the first VM without resynchronizing the second VM with the first VM, if output of the second VM is not diverging from output of the first VM. The output of the second VM is compared with the output of the first VM to determine whether the output of the second VM has diverged from the output of the first VM. In response to a determination that the output of the second VM has diverged from the output of the first VM, a resynchronization of the second VM is executed.

Abstract: Embodiments of the present invention enable users to extract knowledge from testing scenarios performed during application development, and later employ that knowledge to interpret application usage scenarios to enhance serviceability of applications by expediting identification and solving of problems. In an exemplary embodiment, log data generated during simulation of test cases is analyzed to create one or more rules based on patterns in which one or more log entries appear in the log data. Later, log data may be analyzed to look for a pattern of log entries that matches a pattern-based rule, thereby facilitating faster identification and resolution of the problem.

Abstract: Techniques are provided to manage how router advertisement messages are forwarded for ultimate wireless transmission in a wireless network. In one embodiment, a multicast router advertisement message intended for a virtual local area network is converted into individual unicast router advertisement messages directed to specific wireless mobile client devices that are part of that virtual local area network. In another embodiment, router advertisement messages are routed between controllers according to the current location of a wireless mobile client device. In still other embodiments, techniques are provided to minimize the volume of the router advertisement messages sent over a wireless network, and to proactively send a unicast router advertisement message to a mobile client device that has performed a handoff, without waiting for a router solicitation message.

Embodiments of the present invention can be used to determine an optimal log analysis location and ensure that the log file is processed at the optimal location based, at least in part, on the log file size and available network bandwidth.

Abstract: A method of operating a transmission includes measuring an output torque, estimating a gearbox input torque using a model, and estimating gearbox component torques based on a detailed gearbox model. The model used to estimate the input torque varies depending on whether a torque converter is locked, open, or slipping. In some operating conditions, multiple estimates are available for gearbox input torque, impeller torque, or shift element torque in which case the models are adapted. When an estimated component torque is outside an expected range, a warning flag is raised and diagnostic data is saved. When an estimated torque approaches or exceeds a torque limit, the input torque command may be reduced to prevent component damage. A warning flag may also be raised and diagnostic data saved in response to a model parameter being adapted to a value outside of a predetermined range.

Abstract: Systems, methods, and other embodiments associated with a unit of work for incremental data processing are described. In one embodiment, a method includes selecting a unit of work key for a program that processes records in a source table. The unit of work key is selected such that modifications to a record having a certain unit of work key value will not affect the program's processing of records having a different unit of work key value. The selected unit of work key is associated with the program. When a record in the source table is created, modified, or deleted, a unit of work key value is identified for the record and a selected set of records having the identified unit of work key value is provided to the program. Thus, records in the data source that do not have the identified unit of work key values are not provided to the program.

A backup set comprising files to be backed up are then generated from the set of unique files and backup is scheduled in the order in which the files to be backed up are identified. Unique files are generated based on file sharing patterns and communications among users that enable generating a social network graph from which one or more communities can be detected and deduplication can be performed on the files hosted by client systems in these communities thereby conserving resources.

Abstract: The disclosure generally relates to detecting playback buffer underrun at a sink device to improve streaming media quality. More particularly, according to various embodiments, a media source device may establish a connection with the sink device according to a short-range wireless communication protocol (e.g., Bluetooth) and stream multimedia data to the sink device over the established connection. The sink device may then store the streamed multimedia data in a playback buffer, render the streamed multimedia data from the playback buffer, and send a signal to the source device to indicate a status associated with the playback buffer. Accordingly, the source device may increase local resources allocated to streaming the multimedia data to the sink device in response to the status signal indicating an underrun condition in the playback buffer at the sink device (e.g., where the buffered multimedia data stored therein has fallen below a threshold).

Abstract: Features are disclosed for performing speech recognition on utterances using a grammar and a statistical language model, such as an n-gram model. States of the grammar may correspond to states of the statistical language model. Speech recognition may be initiated using the grammar. At a given state of the grammar, speech recognition may continue at a corresponding state of the statistical language model. Speech recognition may continue using the grammar in parallel with the statistical language model, or it may continue using the statistical language model exclusively. Scores associated with the correspondences between states (e.g., backoff arcs) may be determined according to a heuristically or based on test data.
