One Plug-In Sensor Does Work of Many

The sensor board can be plugged in to a wall outlet, eliminating the need for batteries.

Researchers have developed a sensor package that monitors multiple phenomena in a room using machine-learning techniques. The prototype contained 19 different sensor channels, including sensors that indirectly detect sound, vibration, motion, color, light intensity, speed, and direction. The sensor board is plugged in to a wall outlet, eliminating the need for batteries.

Pulsed Phase Noise Measurements: Challenges and Solutions

Thanks to advances in digital signal processing techniques, wireless communications and radar systems have become increasingly digital. Constraints have also been placed on packing more information into less bandwidth. For both systems, one of the key RF parameters that limits performance is phase noise.

Virtual Hardware ECU: How to Significantly Increase Testing Throughput

In Conjunction with SAE

Both the complexity and software content of automotive electronic systems are increasing rapidly. At the same time, the demand for more software and system testing is growing. This need is being driven by requirements from the ISO 26262 standard and the necessity to reduce software-driven recalls, which have been significantly rising over the past few years.

Connectivity Solutions - Keeping Pace with the Rapid Evolution of Embedded Computing Systems

Embedded Computing is seeing a rapid evolution in system design. New defense platforms and system upgrades are widely adopting open architecture standards like VPX in place of 20+ year old technologies. Defense-grade processors are now achieving 28Gbps data rates with significant I/O count, which drives increased functionality and enables computing hardware to shrink in size and weight.

Giant shipworm could reveal clues about human medicine, bacterial infections

Northeastern professor Daniel Distel and his colleagues have discovered a dark, slithering 4-foot-long creature that dwells in the foul mud of a remote lagoon in the Philippines. They say studying the animal, a giant shipworm with pinkish siphons at one end and an eyeless head at the other, could add to our understanding of how bacteria cause infections and, in turn, how we might adapt to tolerate or even benefit from them.

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).
