Neurofeedback is a machine-mediated noninvasive treatment modality based on the analysis and " feeding back" of electroencephalogram brainwaves, which has shown efficacy with a variety of central nervous system-based problems. It has special application where patients have adverse reaction to psychopharmacologic treatments and psychotherapy, cognitive behavioral therapy, and dialectical behavior therapy have proved ineffective. Treatment modalities include active forms based on operant conditioning, involving a subject's response to stimuli. Neurofeedback is strong in clinical confirmations of efficacy (case studies) and has thus far limited controlled studies in the peer-reviewed journals. © 2013 Elsevier Inc..

Package-on-Package (PoP) has many advantages, small foot-print, better performance, easier to debug, and better control over supply chain, etc. Recently PoP integration architecture based on fan out wafer level package (FOWLP) and through mold connection (TMC), demonstrated and many back-end manufacturing houses completed the qualification and migration to this architecture. Despite the cost and performance benefits with this new architecture, the assembly process is complex. Traditional SMT process for chip-Attach and die attach are being leveraged but require close monitoring. The registration and volume of screen-printed materials, solder paste and solder flux need stringent control. The accuracy requirement for die placement coupled with thin die handling challenges warrants continuous monitoring for this process step. Further, TMC formations, laser drilling, and bumping require close monitoring. To address these metrology challenges, Koh Young developed a versatile sensor, rapid area scan interferometer (RASI), an area scan interferometer that can measure thickness and volume on all kinds of materials, highly reflective, diffusive, opaque, semi-Transparent, and transparent materials. The sensor has measurement repeatability in nanometers at the same time RASI innovative instrumentation provides inspection speed that exceeds throughput requirements of IC package assembly line. © 2016 IEEE.

The challenges of in-mold labeling (IML) need to be addressed for a continued product security. Long and complex supply chain are involved in implementing an IML project. Multiple disciplines and companies are involved to develop a good plan for IML, which means early involvement of all the stakeholders. Because of the complex nature of designing and building a mold to accommodate IML, early collaboration by all the participating companies is essential for any project's success. The biggest challenge to the part and mold design, which also impacts the automation and label placement, is the gate location. Electric machines are generally preferable for IML applications since their components do not vary over time nearly as much as those of hydraulic machines. The automation considerations for IML include the shape of the labels, the materials from which the labels are made, and how to statically charge them.

Thin Solid Films | Year: 2010
Indium tin oxide (ITO) thin layers were deposited onto glass substrates by RF magnetron sputtering using different pressures. Subsequently, the films were annealed in a reducing atmosphere at 500 °C for 30 min. Electrical properties were measured by Hall Effect analysis and four-point probe measurements. Optical properties were determined by UV-Vis spectrophotometery. Film structures and compositions were analyzed by X-ray diffractometry and X-ray photoelectron spectroscopy, respectively. The effect of sputter pressure and additional anneals was investigated. The results revealed that the lowest resistivity of 1.69 × 10- 4 Ω cm was achieved at low pressure (1.2 Pa) and the highest transmittance of ~ 90% was obtained after a second anneal. However, the second anneal decreased the mobility and the conductivity especially for high sputtering pressures. This study also describes the effect of Sn defect clustering on electrical properties of the ITO films. © 2009 Elsevier B.V. All rights reserved.

Recently, there has been a large increase in the incorporation of nanoscale ingredients into polymers in order to increase performance. Use of clays for transport and food packaging applications are now commonplace, providing weight reduction and barrier properties. Carbon nanotube-based materials are also being developed, not just for light-weighting, but for applications using their ability to conduct a charge; hence fuel pumps and fuel lines for cars have appeared as early applications. There is a great deal of work now being carried out on graphene-based nanopolymers which heralds the next exciting phase in nanopolymer development. The patent situation and societal aspects in this field need to be addressed in a realistic and professional manner.

The Federal Aviation Administration (FAA) and Coast Guard recently adapted increases in the average passenger weight used to calculate load and conduct safety analysis and tests in multiple modes of transportation. The Federal Transit Authority (FTA) has proposed similar measures. The increased passenger weight requirements were created in response to the Center for Disease Control's (CDC) documented rise in weight among the country's citizens and followed crash or failure incidents in which a cause was overweight equipment. The current certification requirements under CFR 49, Part 567 state that Gross Vehicle Weight Rating (GVWR) of a motor vehicle shall not be less than the sum of the unloaded vehicle weight, rated cargo weight and 150 pounds (68 kg) times the number of designated seating positions. Actual occupant weight distributions versus certified weight per occupant seat causes a potential conflict between a vehicle's in-use weight versus its certified GVWR. A Monte Carlo method using a midsized bus example was conducted to determine the statistical probability that adult passengers and rated cargo would result in weight distributions that exceeded tire load capability, Gross Axle Weight Rating (GAWR), or GVWR. A discrete distribution of occupant weight modeled on the 2006 CDC anthropometric reference data was utilized. The analysis examined buses loaded with fewer occupants than seating positions by assuming a uniform probability that a seat would be occupied. Results demonstrated that load conditions and usage restrictions can be identified that decrease the probability of operating in a condition that exceeds a weight rating.

The current certification requirements under CFR 49, Part 567 state that GVWR of a motor vehicle shall not be less than the sum of the unloaded vehicle weight, rated cargo weight and 150 pounds times the number of designated seating positions. Actual occupant weight distributions versus certified weight per occupant seat causes a potential conflict between a vehicle's in-use weights versus its certified GVWR. Population weight distributions were developed based upon The Center for Disease Control's (CDC) publication of 2007 - 2010 anthropometric reference data and publically available weights of a special population from high school football teams. For five buses from small (18-seat) to large (55-seat), key parameters were measured. The weight distributions and bus parametric data were combined in a probabilistic analysis to explore the probability that passengers and rated cargo would result in weight distributions that exceeded tire load capability, Gross Axle Weight Rating (GAWR), or Gross vehicle Weight Rating (GVWR). The scope of the paper does not investigate whether increasing the required weight per seat would produce net benefit, but, given historical usage and understandings and recent requirements for objective test criteria, an objectively derived and, if judged necessary, updated occupant weight per seat requirement is suggested. Results demonstrated that load conditions and usage restrictions are identifiable that decrease the probability of operating in a condition that exceeds a tire or vehicle weight rating. The analysis of this paper supports that a median unclothed adult weight of at least 79.3 kg (175 pounds) which would represent an equal male and female population of all race and ethnicity in the United States of America should be considered.

This work directly addresses a technology of interest listed in Section 9, sub-section H1.01 In-Situ Resource Utilization, specifically "Highly efficient reactors for carbon monoxide/carbon dioxide (CO/CO2) conversion into methane (CH4)."The proposal will investigate combining recent work that demonstrates outstanding CO2 sorption by third generation ionic liquids (ILs) without an increase in viscosity (even in the presence of water) with adaptations of recently developed methodology for electrochemically reducing and polymerizing CO2 in an aqueous IL to polyethylene. The intention is to demonstrate that this methodology is an excellent candidate for creating a highly efficient reactor for carbon dioxide conversion to methane. Unlike conventional electrolytes, ILs generally have very low vapor pressures. This will make it possible for them to be used in the much lower pressure Martian atmosphere without the problem of evaporation.Our goal is to build on the results achieved by other research groups by using our own knowledge and years of experience working with ILs, including electrochemistry, to efficiently reduce CO2. We will prepare the task-specific 3rd generation ILs and then measure their electrochemical properties; i.e., conductivity, electrochemical window, etc. These are currently unknown but are important in order to ascertain whether these ILs are suitable for this application. Anticipating this will be the case, we will then test various electrodes, including TiO2 and silver cathodes, to determine which gives the most selective reduction of CO2 to methane. The efficiency of the process (including power requirements) will be quantified and compared to the Sebatier and Fischer-Tropsch processes.

The objective of this work is to determine the optimal process for manufacturing lightweight linerless cryogenic storage tanks using ionic liquid epoxy composite material that can compete with metallic tanks currently in use.Ionic liquids, because of their unique properties such as low volatility, low flammability, and flexibility of chemical design are showing promise as the next generation of chemical reagents. Mechanical and chemical testing to date has shown that this IL epoxy monomer, when cured with a commercial aromatic diamine curing agent, yields a polymer resin with high tensile strength, excellent bond strength to aluminum and steel, high toughness, low CTE, and low moisture permeability. Performance comparisons of the ILE to several commercial epoxies showed the ILE had superior tensile and bond strengths. Of particular importance is that these properties of the ILE were even better at cryogenic temperatures because of the low crystallinity inherent in the polymer as a consequence of the chemical nature of ionic liquids.In this Phase I effort, a battery of tests will be carried out at room and liquid nitrogen temperatures on coupons prepared preferably on a filament winder using the wet winding technique. Hand layup may also be used to make small defect-free samples. Samples for tensile, lap-shear and bend (for interlaminar shear strength) will be cut from these. Potholing or surface degradation, microcracking and delamination will be reported and quantified if found.
