Abstract: A computer implemented method of creating a clustering model used for clustering a plurality of log messages comprising using one or more processors for receiving a plurality of training log messages, performing the following for each of the plurality of training log messages: calculating a string distance between a textual content of the respective training log message and a representative string pattern of each of the plurality of clusters, associating the respective training log message with a respective one of the plurality of clusters in case the string distance is within a predefined threshold and adding a new cluster to the plurality of clusters for associating respective training log message in case the string distance exceeds the predefined threshold, and outputting the clustering model.

Abstract: A method, system and computer program product for database search enhancement and interactive user interface therefor. Database records are ranked by a match score, calculated using a plurality of criteria for determining a match level between values of a record and a search query, and using a plurality of priority parameters for aggregating the match level determined. A plurality of top-ranking records is selected, and a diversity measure is calculated therefor, using at least one class label assigned to records therein. If a sufficiency condition is not met by the diversity measure, at least one reference set of records sharing a class label in common is extracted from the plurality of top-ranking records and analyzed for determining at least one modification to the search query in improvement of the diversity measure, the scoring computational operator is accordingly redefined, and the process reiterates; otherwise, the plurality of top-ranking records is outputted.

Abstract: A weapon sight, including a photon energy harvesting device configured to accept photon energy from light surrounding the weapon sight, an electrical energy storing element configured to store electrical energy from the photon energy harvesting device in the form of an electric field, a load configured to be powered by the electrical energy storing element, a voltage regulator configured to limit the release rate of current from the electrical energy storing element to power the load.

Abstract: A method, system and computer program product for enhanced database and user interface incorporating predicted missing data. A reference record in a database comprising a plurality of values divided into a plurality of categories is received. A comparison computational operator for calculating similarity score is defined using criteria for determining a level of match between values of the reference record and a record compared thereto in each of the plurality of categories. Top ranked records according to the similarity score are selected, and for values included therein in a category of the plurality of categories, a frequency score comprising a count aggregated per similarity score of containing records is calculated and according thereto a set of missing values in the reference record is selected for enhancement of the reference record and/or presentation via a user interface.
