Abstract: A battery power station including a top panel, a base, and side panels which define a structure, and a first removable end panel and a second removable end panel. The battery power station includes an electronics compartment within the structure including at least one printed circuit board, and a battery compartment within the structure configured to receive a battery pack module. The base includes lateral protrusions having a hook structure configured to interdigitate with corresponding hook structure of the side panels forming a seal between the base and the side panels. The first and second removable end panels include a shell having protrusions extending from an inner surface of the shell and around a periphery of the shell, the protrusions configured to create a seal with the structure forming a seal between the structure and the first and second removable end panels.

Abstract: A system for extracting information from text, the system including parsing functionality operative to parse a text using a grammar, the parsing functionality including named entity recognition functionality operative to recognize named entities and recognition probabilities associated therewith and relationship extraction functionality operative to utilize the named entities and the probabilities to determine relationships between the named entities, and storage functionality operative to store outputs of the parsing functionality in a database.

Abstract: A computer-implemented method for information extraction includes defining a stochastic context free grammar (SCFG) including symbols and rules applicable to the symbols, the symbols including at least one output concept. The SCFG is trained on a tagged training corpus so as to determine probabilities of the rules and of one or more of the symbols. A document is parsed using the rules and symbols responsively to the probabilities so as to extract occurrences of the at least one output concept from the document.
