Abstract: Disclosed are substance detection and identification devices, and methods of using them for detection and identification of substances in ambient surroundings, on surfaces of objects, inside closed items or in fluids. A substance detection and identification device may comprise a housing, an opening in the housing for passage of sample material therethrough, a sensing unit located in the housing and an array of sensing elements configured and operable to interact with sample material in the vicinity thereof for detecting one or more specific substances and generating sensing data indicative thereof. A sample path defined in the housing between the opening and the sensing unit is used for facilitating flow of the sample material towards the sensing unit.

Abstract: A sensing unit is presented for use in identifying at least one foreign substance in a region of interest. The sensing unit comprises at least one measurement unit, which comprises one or more sensor elements each configured and operable to be responsive to at least one foreign substance in the vicinity thereof. Each sensor element is mounted in its own compartment having an inlet and an outlet thus defining an environmental region in the vicinity of the sensor element separated from the surroundings of the compartment.

Abstract: A cryosurgical instrument, in which a separator is installed in a central feeding lumen and/or in a cryotip to separate gaseous and liquid components of a cryogen.

Abstract: A source multidimensional data model is associated with a target multidimensional data model, for purposes of, for example, copying or linking data between the source and the target. Individual dimensions are mapped from the source to the target. Within each mapped dimension, individual dimension members are mapped from the source to the target. The resulting association may be stored and utilized to generate executable statements for copying or linking data between the source and the target.

Abstract: Importation of data records organized within tables from a source system to a target system while preserving relationships among data records of the tables when record identification values identifying each data record have been changed during importation includes, using the same database query on an entire table to update each record identification references that refers to a data record in another table.
