Abstract: An inkjet printer assembly includes an inkjet carriage assembly having a plurality of side walls and an end wall, the inkjet carriage assembly including a pen guide track extruding from at least one of the side walls and a plurality of datum features formed in the inkjet carriage assembly, and an inkjet dispenser pen having a body, the inkjet dispenser including one or more datum extrusions formed on the body, wherein the one or more datum extrusions are associated with the datum features to assure proper loading of the inkjet dispenser pen into the inkjet carriage assembly.

Abstract: A print cartridge includes a cartridge body having a lower portion and a vertical wall. A printhead is attached to the lower portion of the cartridge body. A contact array having a first pair of columnar arrays of contact areas and a second pair of columnar arrays of contact areas is disposed on the vertical wall of the cartridge. The columnar arrays extending along at least one half of the height of a region occupied by the contact array. The columnar arrays of each pair of columnar arrays converge toward each other in a direction toward the lower portion of the cartridge body.

Abstract: An electrically powered compressor designed for providing high pressure ratio at low flow rate, yet having low power consumption. The compressor is designed for optimizing efficiency in fuel cell systems. The inventive compressors are however not limited to fuel cell system applications.

Abstract: An interconnect system for a device stall adapted to receive an inkjet device having a first set of electrical contact surfaces on a device surface. A second set of electrical contact surfaces is provided in a device stall. Respective ones of the first set and the second set are in facing alignment when the device is installed in the stall. An elastomeric layer is disposed between and in contact with the first and second sets of electrical contact surfaces, having a plurality of isolated conductive filaments or wires disposed therein between a first layer surface and a second layer surface. Conductor ends are exposed at the first and second layer surfaces, providing isolated electrical continuity between respective ones of the first set and the second set of electrical contact surfaces.

Abstract: An improved electrical test probe has a electrically conductive strain relief adapter mounted on a substrate for accepting a conductive cable having a central conductor and an outer shielding conductor separated by a dielectric layer. The conductive cable is inserted into the strain relief adapter with the outer shielding conductor in electrical contact with the adapter. The substrate is disposed within an electrically conductive elongate hollow body with the body being deformed proximate the location of the strain relief adapter to secure the substrate in the body and to provide electrical continuity between the outer shielding conductor and the substrate and the outer shielding conductor and the hollow body. The adapter further provides strain relief for the center conductor of the conductive cable and mechanical support for the substrate.
