Described is a device for machine tools or measuring apparatus for detecting the spatial position of a carriage movable in a coordinate axis along a guide with respect to a reference standard which is designed as a rectangular plate extending parallel to the guide of the carriage. The consumption information, along with real-time contextual information, may be used to generate collections of recommended multimedia content, including obtainable multimedia assets. The sharing instruction generating module generates a sharing instruction when a mobile device is sensed by the display terminal within a predetermined distance. The supporting salt contained in the electrolyte exists only in regions proximate a surface of the polarizing electrodes when the electrical double layer capacitor is fully charged. In the embodiment described the joining structure serves the additional function of acting as a floor panel for vertical loads carried within the well car unit. A second transistor is coupled to the first control terminal and has a second control terminal coupled to the output node.
