Personalized Healthcare Calls for Innovative Wearables and Medical Devices

Because the world population is aging, chronic diseases are on the rise and healthcare costs are reaching unsustainable heights, it is essential to detect pathologies early. The Internet of Things (IoT) is now poised to transform the healthcare industry by providing wireless connectivity and sensing. Body-worn electronics and implanted devices, equipped with tiny sensors that continuously monitor vital parameters and securely report anomalies to appropriate physicians, will improve patients’ quality of life while delivering timely medical help. Personalized healthcare is making medicine participatory, personalized, predictive and preventive (P4 Medicine). Medical device and high-tech companies are joining forces to satisfy a growing demand that might reach 20 billion medical connected devices by 2020. Successful medical device and pharmaceutical companies are using engineering simulation to develop systems that ensure high reliability, provide data privacy and achieve regulatory compliance quickly. Learn how platform-based engineering simulation maximizes the IoT opportunities for personalized medicine.

The Ins and Outs of Spaceflight Passive Components and Assemblies

RF and microwave components deployed in space flight applications can experience hundreds of degrees of temperature variation, massive amounts of radiation, and can be expected to operate at an elevated level for sometimes decades. The demands of operating in a space environment bring many unique challenges and unforgiving reliability requirements; therefore, designing passive components to meet these rigorous operation criteria necessitates a high level of design expertise, qualifications/certifications, and testing capability.

How the Automotive and Ground Transportation Industry is Accelerating with Pervasive Engineering Simulation

Consumers are demanding efficient, reliable, safe, environmentally friendly, smarter, connected and increasingly autonomous vehicles. Regulators continue to demand improvements in safety and emissions. The automotive industry must deliver these increasingly complex products to market faster, in the face of increasing competition from traditional sources, new geographies and new entrants and with continued pressure to reduce cost. Failure of any magnitude can result in significant, and even irreparable, financial and brand impact.

Imaging Detonations of Explosives

Using high-speed camera pyrometers to measure and map fireball/shock expansion velocities.

An effort has been made within the US Army Research Laboratory (ARL) to extract quantitative information on explosive performance from high-speed imaging of explosions. Explosive fireball surface temperatures are measured using imaging pyrometry (2-color 2-camera imaging pyrometer; full-color single-camera imaging pyrometer). Framing cameras are synchronized with pulsed laser illumination to measure fireball/shock expansion velocities, enabling calculation of peak air-shock pressures. Multicamera filtering at different wavelengths enables visualization of light emission by some reactant species participating in energy release during an explosion. Measurement of incident and reflected shock velocities is used to calculate shock energy on a target.

Laser Integration on Silicon Photonic Circuits Through Transfer Printing

New fabrication approach allows the massively parallel transfer of III-V coupons to a silicon photonic target wafer.

The purpose of this project was to develop a transfer printing process for the massively parallel integration of III-V lasers on silicon photonic integrated circuits. Silicon has long offered promise as the ultimate platform for realizing compact photonic integrated circuits (PICs). That promise stems in part from the material's properties: the high refractive-index contrast of silicon allows strong confinement of the optical field, increasing light-matter interaction in a compact space—a particularly important attribute for realizing efficient modulators and high-speed detectors.

Determining Detection and Classification Potential of Munitions Using Advanced EMI Sensors in the Underwater Environment

Electromagnetic induction could be used to locate and characterize potentially dangerous sunken metallic objects.

Hazardous ordnance items are present along coastlines and in rivers and lakes in waters shallow enough to cause concerns for human recreational and industrial activities. The presence of water makes it difficult to detect and remove these hazardous legacies induced from wars, military training and deliberate disposal. Various techniques have been proposed to detect and characterize Unexploded Ordnances (UXO) and discarded military munitions (DMM) in the underwater environment including acoustic waves, magnetometery, and electromagnetic induction (EMI).
