    Abstract: A non-transitory computer readable medium (107, 127) stores instructions readable and executable by at least one electronic processor (101, 113) to perform a suspect device configuration detection method (200). The method includes: extracting a fleet configuration transactions database (130) of device configuration transactions (132) from device log data (108) and/or system configuration files (112) of a fleet of devices (120) wherein each configuration transaction includes one or more support data fields (134), a parameter identifier (136), and its value (138); constructing a configuration outlier detector (140) to identify outlier configuration transactions in the fleet configuration transactions database; detecting one or more suspect configuration transactions (150) by applying the configuration outlier detector to configuration transactions extracted from one or more devices of interest; and generating at least one of an alarm (160) and a report (170) when the one or more suspect configuration transactions are detected.

    Abstract: An alert monitoring method includes receiving alerts generated by one or more medical systems, each alert being timestamped and associated to the medical system that generated the alert; segmenting a displayed time span into discrete time units whose size depends on the displayed time span; generating a timeline representing the alerts over the displayed time span, the timeline comprising a two-dimensional grid of blocks with each block having a corresponding discrete time unit and a corresponding alert source for the one or more medical systems, and each block being color coded based on a fraction of the corresponding discrete time unit over which the corresponding alert is critical; displaying, on a display device, the timeline representing the alerts over the displayed time span; and in response to receiving a user input adjusting the displayed time span, displaying an updated timeline representing the alerts over the updated displayed time span.

    Abstract: Analysis of a log pattern for use in diagnosing a medical imaging device operates on log data including log events and service calls, each associated with a subset of log events within a service call time frame of a call time of the service call. Preprocessing (64) generates normalized log events (66) by removing or replacing content of the log events and linking each normalized log event with one or more service calls. Pre-analysis (68) identifies a test set of normalized log events that match a log pattern (40) and a test set of service calls (42) linked with the test set of normalized log events. The test set of service calls is analyzed (74) to identify hit service calls (46) each belonging to the test set of service calls and for which the log pattern under analysis has a hit.

    Abstract: Automatic generation of questions and evaluation answers about a media item is provided for a system such as a video on demand system. A virtually unlimited number of questions can be generated without the need for subjective information. Questions about a media item are generated by selecting a media segment of the media item. At least part of the media item within the selected media segment is shown to a user. The user is asked to indicate a position within the media item where the user thinks that the segment is located. The indicated position is compared to the actual position of the segment to evaluate the answer.

    Abstract: A non-transitory computer-readable medium stores instructions readable and executable by at least one electronic processor (10, 12, 14) to perform a log pattern analysis method (300) by applying a log pattern to log data undergoing analysis comprising log events which are time stamped and which are defined by values for a set of fields. The log data undergoing analysis are stored on a server (30) accessible by the at least one electronic processor via an electronic network (31). The log pattern analysis method includes: constructing a retrieval query to select log events that are in a time interval and that also satisfy at least one additional constraint associated with the log pattern and defined on one or more filter fields of the set of fields; downloading a sub-set of the log data undergoing analysis from the server to the at least one electronic processor via the electronic network, wherein the sub-set is selected from the log data undergoing analysis by the retrieval query; applying the log pattern to the downloaded sub-set of the log data undergoing analysis to identify log pattern hits in the log data undergoing analysis; and controlling a display screen (16) to display a report of the log pattern hits in the log data undergoing analysis.
