The work solves the problem of task and motion planning of a self-reconfigurable fixture system. A feasible solution is a key requirement for the viability of such systems, which have raised hopes of overcoming the deficiencies that more traditional fixtures are recognized to have in the dynamic conditions of modern manufacturing, with its increasing emphasis on flexibility, adaptability, and a...

Traditionally, fixtures have been required to be redesigned and remanufactured for every new product or manufacturing operation. Although this kind of fixturing practice might be economical for mass production, it would cause long lead times and high (fixture) manufacturing costs in small batch production. In today's flexible automation approach to small batch production, reconfigurable fixture...

The circuit board manufacturing community is now ready to embrace the concept of moving probe in-circuit test systems, also known as Flying Probers. This is due not only to the ability of Flying Probers to eliminate the cost of fixturing, but also to their new ability to satisfy the overall test requirements. This opens up the opportunity to test a new class of boards that are not cost effectiv...

This case study provides a comprehensive look at Talecris 1 Biotherapeutics' approach to PAT and automation followed by examples of PAT deployed on a bioprocess. It introduces the concept of integrated and scalable automation, provides a comparison of automation concepts, and explains how the selected automation effectively supports initiatives like PAT. Figure 1. PAT model for the Talecris Cla...

The article contains the rationale for the development of the computer-aided fixture design system (CAFD). The place of the CAFD among other automated systems is considered and the data flows are found between them. The structure of the CAFD system is suggested, which is distinguished by the module of optimization and allows to select the optimal fixture for the given production conditions. The...

This paper presents the characterization of a PCI-express test fixture that was created to passively probe a x16 link on a PCB. This fixture plugs into the 48-pin, midbus footprint which has been adopted by as the industry standard for observing PCIexpress links on a PCB. This fixture is used to observe signals and pass them to a piece of test equipment (TDR, VNA, or oscilloscope). Engineers re...

OBJECTIVE To investigate microbiological biofilm contamination of retrieved bone-anchored hearing aids. MATERIALS AND METHODS Nine failed, retrieved bone-anchored hearing aids and 16 internal screws were examined by scanning electron microscopy. A fixture from a failing implant, which had been removed and disassembled under aseptic conditions, was cultured. Finally, an internal screw from a n...

This paper presents basic reliability evaluation techniques needed to evaluate the reliability of distribution systems which are applied in distribution system planning and operation. In this paper we consider seven different alternatives and examined on distribution system. Basically the reliability study can also help to predict the reliability performance of the system after quantifying the ...

The purpose of this paper is to present an automated design methodology for analog blocks. This method focuses on analog blocks design parameters automatic generation according to specific design constraints. This method is based on analog circuits’ mathematical models. These models are generated thanks to a “Design Of Experiment” (DOE) technique. The DOE technique takes as input electrical sim...
