Abstract: Material conveyance devices with actively powered Radio Frequency Identification (RFID) tags are described herein. The material conveyance devices motion is converted to electrical energy which is used to either recharge the RFID tags energy storage device or directly power the RFID tag.

Abstract: Systems and methods for verifying a materials processing path on a work piece are described. In one embodiment, a system for verifying a material process path on a work piece includes a processing unit operable to receive processing instructions to control a motion of a machine tool device relative to a work piece. A tool holder of the machine tool device retains a tool path tracing assembly that applies a mark to a surface of the work piece as the assembly is moved along the material process path.

Abstract: A hydraulic subassembly is preassembled outside the vehicle into which it is later installed, using an assembly tool. The components of the subassembly are fastened in predetermined positions on the assembly tool, following which hydraulic connections are made between the components. The completed subassembly is fastened to a pickup tool and then disconnected from the assembly tool, allowing an assembly operator to lift the subassembly away from the assembly tool and carry it to the vehicle for installation. The pickup tool is also used to position and hold the subassembly within the vehicle while the subassembly is being connected to hydraulic systems on the vehicle. Following installation of the subassembly, the pickup tool is unfastened from the subassembly and removed from the vehicle.

Abstract: A system for certifying laser projection beam accuracy includes a certification fixture having a test pattern and a color background. The certification fixture is configured so that any portion of the laser projection beam reflected from the color background is reflected with a color contrasting to that of the laser beam or of the test pattern. Contrast can be further enhanced by making the pattern of a material that absorbs the laser beam color. Failure of the test is indicated by the presence of any of the laser beam light reflecting from the background. Passage of the test is indicated by the laser beam striking only the test pattern. A functional test pattern tests for both laser beam width and positioning accuracy. A method is provided to use a calibration test pattern to test laser beam width and length projection accuracy independently of one another.

Abstract: A method is disclosed for aligning a laser projection device with a subject article. The method comprises the utilization of specially adapted mounts to secure reflective targets to specific geometric features of such a subject article. By mounting the laser target devices to the subject article itself, tooling jigs are not necessary and the targets can be easily positioned at various locations to avoid laser beam obstruction concerns and to ensure accurate alignment.

Abstract: A device for securely clamping a drill motor to a drill plate in order to drill precisely positioned holes in a workpiece includes an annular mandrel and annular collet concentrically disposed about the cutting element. A first end of the collet includes a plurality of longitudinally extending fingers while the mandrel has a tapered end portion having a larger external diameter than the center cylindrical portion of the mandrel. A pneumatically-actuated piston is also coaxially disposed about the cutting element to extend and retract the mandrel and the collet. Once extended, the longitudinally extending fingers of the collet overlie the center cylindrical portion of the mandrel. Thus, the clamping device may be inserted through an aperture defined in a drill plate. Following its retraction, the longitudinally extending fingers of the collet overlie the tapered end of the mandrel and are correspondingly expanded.

Abstract: A grommet installation device consisting of an installation tool and a backup tool. The backup tool incorporates a retractable rod for guiding and aligning the grommet sleeve throughout installation. The installation tool flares and swages the grommet sleeve over a grommet spacer, affixing the grommet assembly in the workpiece aperture.
