Abstract: An apparatus, a system and a method for the detection of an analyte in air comprising an air sampling system (1) comprising a mouthpiece (10) and a fan, a first enrichment stage (11) for enrichment of the analyte comprising a thermally regulated adsorption/desorption filter (20) creating a non-laminar gas flow for adsorption of the analyte, a heat source for heating the filter to evaporate the analyte, a second enrichment stage (30) for the further enrichment of the gaseous analyte comprising a cold trap (32) for condensing the analyte, extraction of the condensed material with a solvent, and collecting the solution, and analyzing the collected liquid sample with an analytical detection system, are disclosed. Further, an adsoption/desorption filter creating a non-laminar gas flow comprising a winding (21) of a resistance wire coated with an active material electric heating of the wire, is described. A specific application is detection of a gaseous component of explosives or mines, e.g. TNT, in air.

Abstract: A tool for chip-removing machining includes an insert holder and an insert that is mechanically connected with the holder via upper and lower interfaces. Each interface includes a pair of contact surfaces that extend at an obtuse angle relative to each other. Disposed centrally between one of those pairs of contact surfaces is a ridge, and disposed centrally between the other pair of contact surfaces there is a flute. Each of the recess and flute is defined by side surfaces that extend at an acute angle relative to each other. When the ridge engages the flute, a proper absorption of transverse forces acting upon the insert is guaranteed, whereby the insert is maintained essentially immovable in its position in order to guarantee a proper machining accuracy.

Abstract: A handoff system where handoff requests are initiated not only by a home or serving base station, but also by neighboring base stations. As in conventional handoff, a serving base station may initiate a handoff request when the signal strength of one of its mobile stations falls below a predetermined threshold. In addition, neighboring base stations monitor the signal strength of neighboring mobile stations and request that a neighboring mobile station be handed off when that signal strength reaches a predetermined level. Thus, a handoff request may come from the serving base station because of a poor call connection or from a neighboring base station because of a possible strong call connection.
