A computer-implemented system and method for augmenting search queries using glossaries is provided. At least one search query of one or more search terms is received. A set of tagged documents each associated with a tag and a glossary for the tag is accessed. The glossary includes one or more terms selected from that tagged document, definitions for the terms, and aliases for the terms. The search query is compared to the glossaries in the set. One or more terms in at least one of the glossaries that are related to the search terms of the search query are selected for inclusion in the search query.

An energy storage system employing a reversible salination-desalination process includes an electrochemical desalination battery (EDB) unit including an anode and a cathode. The EDB unit runs a salination process while storing energy from a direct current power supply unit, and runs a desalination process while releasing energy to an electrical load. The energy storage system can store power from a variable output electrical power supply unit such as solar cells and wind turbines while running a salination process, and release energy, e.g., during peak energy demand hours while running a desalination process. Combined with a capacitive deionization (CD) unit, the energy storage system can generate fresh water by running desalination processes in the EDB unit and the CD unit while releasing stored energy from the EDB unit. The energy storage unit can function as a dual purpose device for energy storage and fresh water generation.

A single-pass imaging system utilizes a two-dimensional (2D) light field generator (e.g., one or more VCSEL devices) to generate a modulated two-dimensional modulated light field in accordance with image data for a single row of pixels, and an anamorphic optical system that concentrates the two-dimensional modulated light field in a process direction such that a one-dimensional scan line image extending in a cross-process direction is generated on an imaging surface. The VCSEL array is configured using a scan line image data group made up of pixel image data portions, with associated groups of light emitting elements aligned in the process direction being configured by each pixel image data portion. Gray scaling is achieved either by turning on some of the light emitting elements of the associated group, or by turning the light emitting elements of the associated group partially on, e.g. using a common drive current.

A system and method for generating labels to characterize message content are provided. At least one component, associated with a document, is extracted from a message. Words regarding the extracted component are extracted from the message as candidate labels. Those candidate labels that are discriminative of the document associated with the extracted component are identified by comparing the candidate labels for the component with other candidate labels extracted from other messages with at least one of a same and a different component. Content of the message is characterized using the discriminative candidate labels.
