The predetermined region(s) is/are predetermined by a cross-section geometry of the product in the respective layer and is/are stored in the control device, and the curable material is applied in a plurality of consecutive layers to produce the three-dimensional product. The control device and the application device are further designed such that in the second mode of application one or more colors are applied to predetermined regions of a print substrate material connected to the substrate carrier device to produce a monochrome or polychrome print.

Composite fiber optic cables having exposed, conductive traces external to the cable jacket enable non-invasive, wireless electrical tone tracing of fiber optic cables. The cross sectional geometry of the fiber optic cable prevents conductive traces from short circuiting when abutting other cables or grounded conductive elements. Moreover, the structure allows convenient electrical contact to the conductive traces at any location along the longitudinal extent of the cable without requiring penetration of the cable jacket or removal of fiber optic connectors. Traceable fiber optic cables of various types are disclosed, including simplex, duplex and ribbon cables. Systems of traceable cables utilizing connectors with integrated electrical antenna elements attached to the conductive elements of cable and RFID tags for remote connector port identification are further disclosed.

Apparatus for sensing and characterizing particles (e.g., blood cells or ceramic powders) suspended in a liquid medium comprises a conduit through which the particle suspension is caused to pass simultaneously with an electrical current. According to the invention, the interior wall of the conduit effectively varies in resistivity along the length of the conduit to define a delimited central region of high electrical resistivity which is smoothly contiguous on its opposing boundaries to uninsulated distal elements of lesser electrical resistivity. The delimited central region of the conduit functions as a Coulter volumeter conduit. The uninsulated distal elements of the conduit are made to have a dimension along the conduit wall which is at least equal to the axial extent of the effective ambit electric fields of a traditional Coulter volumeter conduit having a cross-sectional geometry identical to that of the delimited central region of high resistivity in the improved volumeter conduit. According to a preferred embodiment of the invention, the delimited central region of the improved volumeter conduit is defined by a traditional Coulter conduit wafer, i.e., a dielectric wafer containing a central circular conduit, and the distal elements of lesser resistivity are defined by uninsulated, electrically conductive, circular collars attached to opposite sides of the conduit wafer. The conduit in the conduit wafer and the openings in the conductive collars collectively form a hydrodynamically smooth volumeter conduit, in which the electric and hydrodynamic fields of the traditional volumeter conduit are advantageously amended in the manner above noted.

The invention provides a technique of monitoring the void formation in a damascene interconnection process. According to the invention, a test structure is provided that includes at least two damascene structures that have at least one different cross-sectional geometric parameter. To monitor the void formation, the test structure is cut to expose a cross-sectional view to the damascene structures. The cross-sectional view is then inspected and the void formation is investigated in each of the damascene structures. The invention is particularly applicable to multi-level copper-based dual-damascene interconnection processes to monitor the voiding at the interface between barrier layers and bottom metal trenches. The invention allows monitoring of the void formation by locating only one structure on the chip and performing only one cut.
