bit selection algorithm suitable for High Volume Production of sram puf
Hardware-Oriented Security and Trust, 2014Co-Authors: Kan Xiao, Md Tauhidur Rahman, Domenic Forte, Yu Huang, Mei Su, Mohammad TehranipoorAbstract:Physically Unclonable Functions (PUFs) are impacted by environmental variations and aging which can reduce their acceptance in identification and authentication applications. Prior approaches to improve PUF reliability include bit analysis across environmental conditions, better design, and post-processing error correction, but these are of High cost in terms of test time and design overheads, making them unsuitable for High Volume Production. In this paper, we aim to address this issue for SRAM PUFs with novel bit analysis and bit selection algorithms. Our analysis of real SRAM PUFs reveals (i) critical conditions on which to select stable SRAM cells for PUF at low-cost (ii) unexplored spatial correlation between stable bits, i.e., cells that are the most stable tend to be surrounded by stable cells determined during enrollment. We develop a bit selection procedure around these observations that produces very stable bits for the PUF generated ID/key. Experimental data from real SRAM PUFs show that our approaches can effectively reduce number of errors in PUF IDs/keys with fewer enrollment steps.

High Volume Production of low loss sapphire optical fibers by saphikon efg edge defined film fed growth method
BiOS '98 International Biomedical Optics Symposium, 1998Co-Authors: Jeremiah J Fitzgibbon, Joseph M CollinsAbstract:Sapphire fibers grown using the Saphikon EFG technique have proven to be effective delivery systems for Erbium:YAG and Erbium:YSGG laser energy. A special emphasis has been given to the hard tissue dental application following the FDA approval of this procedure in May of 1997. A range of sensor applications also utilize these EFG sapphire fibers. Through the latter half of 1997, Saphikon has successfully transitioned the process from a research/pilot scale level to High Volume Production. Fiber losses as low as 0.2 dB/meter with an average of 1.5 dB/meter, which were first demonstrated on a research level in which tens of meters were produced, have now been sustained over thousands of meters in full scale Production. Use of sapphire fibers in non-medical applications, erbium laser dentistry, and other medical procedures is discussed.

a novel technology for the High Volume Production of intelligent composite structures with integrated piezoceramic sensors and electronic components
Sensors and Actuators A-physical, 2013Co-Authors: Andreas Weder, Sirko Geller, Thomas Tyczynski, Werner Hufenbach, Andreas Heinig, Wolf-joachim FischerAbstract:Abstract The automated High-Volume Production of lightweight and intelligent composite parts is one of the key technologies for the automotive industry. Modern concepts introduce intelligent parts by integrating sensor networks into the composite. These networks record different physical signals and can even work as active components. A popular application scenario is the permanent structural health monitoring. This paper presents a novel High-Volume Production technology that addresses the integration of large piezoceramic sensor and actuator elements in glass fibre polyurethane composite parts using the Multi-Fibre-Injection (MFI) spraying technology. By directly integrating the piezo fibres, this technology combines sensor Production and part Production into one single step. First experiments showed that such piezoceramic sensors are functional. Other experiments demonstrated the successful integration of different electronic components and batteries into composite parts.

Process Chain Modelling and Analysis for the High-Volume Production of Thermoplastic Composites with Embedded Piezoceramic Modules
Smart Materials Research, 2013Co-Authors: Werner Hufenbach, Maik Gude, Niels Modler, Th. Heber, Anja Winkler, T. WeberAbstract:Active composite structures based on thermoplastic matrix systems are Highly suited to applications in lightweight structures ready for series Production. The integration of additional functional components such as material-embedded piezoceramic actuators and sensors and an electronic network facilitates the targeted control and manipulation of structural behaviour. The current delay in the widespread application of such adaptive structures is primarily attributable to a lack of appropriate manufacturing technologies. It is against this backdrop that this paper contributes to the development of a novel manufacturing process chain characterized by robustness and efficiency and based on hot-pressing techniques tailored to specific materials and actuators. Special consideration is given to detailed process chain modelling and analysis focusing on interactions between technical and technological aspects. The development of a continuous process chain by means of the analysis of parameter influences is described. In conclusion, the use of parameter manipulation to successfully realize a unique manufacturing line designed for the High-Volume Production of adaptive thermoplastic composite structures is demonstrated.

on the yield of millimeter wave bond wire antennas in High Volume Production
IEEE Transactions on Antennas and Propagation, 2013Co-Authors: U Johannsen, A B SmoldersAbstract:For the development of Highly integrated millimeter-wave front-end modules, a low-cost and High-performance antenna technology is of paramount importance. Here, standard wire-bond technology is a very attractive candidate due to its widespread availability, computationally efficient modeling options, and promising performance as an antenna. A concern often stated with respect to antennas in this technology, however, is its expected low yield in High Volume Production. This concern is addressed in this communication by means of a dedicated, computationally efficient antenna model in conjunction with standard deviations of state-of-the-art wire-bonders. The results indicate a possible yield of larger than 99.9% for operating frequencies of up to 250 GHz.
