Infrared Lighting Module

Vision Components (Ettlingen, Germany) has introduced the new VC Flash infrared area lighting for OEMs. The lighting module has been developed specifically for traffic surveillance applications. Fitted with 24 high power LEDs, it ensures optimal brightness in mobile and stationary ANPR/ALPR applications, red light enforcement, access control, and toll collection without a glare effect that could endanger drivers. VC Flash illuminates an area measuring 7.5 by 5.0 m from 20 m away. The module measures 195 x 80 x 20 mm, and operates with a central wavelength of 850 nm and a spectral width of 30 nm. Power consumption peaks at 36 W for the highest pulse duration and pulse frequency levels.

UAV Can Launch Aerial Missions from Underwater

Researchers at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, have developed an innovative unmanned aerial vehicle (UAV) that can stay on station beneath the water until needed, then launch into the air to perform a variety of missions. The Corrosion Resistant Aerial Covert Unmanned Nautical System — or CRACUNS — is a submersible UAV that can be launched from a fixed position underwater, or from an unmanned underwater vehicle (UUV). A team from APL’s Force Projection Sector worked with fabrication experts in the Research and Exploratory Development Department to create a new type of unmanned vehicle that can operate effectively in two very different arenas: air and water.

Detecting Radioactive Material from a Remote Distance

In 2004 British national Dhiren Barot was arrested for conspiring to commit a public nuisance by the use of radioactive materials, among other charges. Authorities claimed that Barot had researched the production of “dirty bombs,” and planned to detonate them in New York City, Washington DC, and other cities.

Tiny UAS Could Be Warfighters’ Eyes in the Sky

The basic small-unit fighting capability of the Army is the squad. One of its weaknesses is broad-area situational awareness, particularly in unfamiliar environments, according to Col. Phil Cheatham, deputy branch chief of the Electronics and Special Developments Branch at the Maneuver Center of Excellence (MCOE), Fort Benning, Georgia. A likely solution? A nano unmanned aerial system (UAS) with reconnaissance capability called the Soldier Borne Sensor (SBS).

Creating Simulated LIDAR Images of Human Poses in a Virtual Laboratory

LIDAR is a partial 3D standoff sensing method that illuminates a target with rotatory or flash laser beams, analyzes the reflected lights, and provides both the distance to the target’s surface and the target’s surface shape. An array of laser reflections can be used to map the facing-side surface of a target object as a partial point cloud. Unlike a 360° surface model generated by a traditional full body scanner, the partial point cloud from a LIDAR is a viewing angle dependent 3D representation of the target shape. The resolution of these maps depends on the density of the laser detector array; a good image of a human may require hundreds of detection pixels to capture enough detail to clearly detect changes in limb positions.

Advanced Sensors for Traumatic Brain Injury (TBI)

The objective of this work was to use miniaturized, state-of-the-art pressure/temperature sensors engineered at Lawrence Livermore National Laboratory (LLNL) to measure the immediate increases in intracranial pressure (ICP) combined with longer-term measurements of biological ICP and intracranial temperature. The experience gathered from this work provided valuable data on sensor placement, long-term brain tissue responses to implanted sensors, and sensor capability of dual measurement of biologic ICP and impact pressure transients.

Molecularly Imprinted Polymer (MIP)-Coated Microbeam MEMS Sensor for Chemical Detection

Monitoring trace gases is of great importance in a wide range of applications. Detecting a diverse range of chemical agents requires an adaptable sensor platform capable of identifying threats before they cause harm. Research and development in hazardous-materials detection technology focuses on increasing speed, sensitivity, and selectivity while reducing size and cost. Although the current state-of-the-art vapor detector (Joint Chemical Agent Detector) is lightweight, handheld, and easily attaches to a belt, it still provides added bulk to a soldier on foot. Recently, microcantilever-based technology has emerged as a viable platform due to its many advantages such as small size, high sensitivity, and low cost. However, microcantilevers lack the inherent ability to selectively identify chemicals of interest. The key to overcoming this challenge is to functionalize the top surface of the microcantilever with a sorbent layer (i.e., polymer) that allows for selective binding between the microbeam and analyte(s) of interest.

Next Generation FPGAs for Electronic Warfare Systems

Designers of virtually all electronic warfare system applications exploit CPUs and FPGAs, each offering unique strengths and advantages for handling a wide range of tasks. This diversity arises from fundamental differences in the devices. FPGAs consist of hardware logic, registers, memories, adders, multipliers and interfaces connected together by the user to perform a specific function. CPUs consist of ALUs, instruction execution engines, cache memory, dedicated I/O and memory ports all connected in a fixed architecture, whose resources are driven by program execution.
