Night Vision Displays

Daisy Data Displays
York Haven, PA

United States Coast Guard officials required night-vision goggle compatibility for the flat panel display systems used in the Lockheed C-130 military aircrafts. To meet the requirement, they recently purchased Fleetmate 7171CA Series thin client flat panel displays with night-vision technology manufactured by Daisy Data Displays.

Fuel Flow Meters

Hoffer Flow Controls
Elizabeth City, NC

Hoffer Flow Controls, Inc. recently received a new contract to supply 575 fuel flow meters as a part of the U.S. Navy’s H-53 heavy lift helicopter fleet upgrade. The most powerful helicopter in the U.S. Military, H-53 helicopters perform many tasks within the U.S. Military including heavy lifting, transport of supplies, combat search, rescue missions and mine sweeping to clear vital shipping lanes. The current H-53 helicopter fleet is slated to remain in service until mid-to-late 2020’s.

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.

Multifunctional Core-Shell and Nano-Channel Design for Nano-Sized Thermosensor

This work focused on developing novel nano-sized thermal sensors based on a multifunctional core/shell and nano-channel design that can be used to measure temperature and retaining thermal history of the biological agents experienced during the testing of agent-defeat weapons.

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.

Armed Forces Are Developing Laser Weapons

Responding to lawmakers' questions about how close the Army is to developing offensive and defensive directed-energy weapons, Mary J. Miller responded: "I believe we're very close." Miller, deputy assistant secretary of the Army for Research and Technology, testified before the House Armed Services Committee's Subcommittee on Emerging Threats and Capabilities recently regarding the Army's Science and Technology (S&T) Program for fiscal year 2017.

Electric Patch Holds Promise for Treating PTSD

An average of 30 years had passed since the traumatic events that had left them depressed, anxious, irritable, hypervigilant, unable to sleep well and prone to nightmares. But for 12 people who were involved in a UCLA-led study — survivors of rape, car accidents, domestic abuse and other traumas — an unobtrusive patch on the forehead provided considerable relief from post-traumatic stress disorder.

Robotic Falcon Captures and Retrieves Renegade Drones

Michigan Technological University is developing a drone catcher that could pursue and capture rogue drones that might threaten military installations, air traffic, sporting events — even the White House. It’s a deceptively simple system: a launcher that shoots a big net attached to a large drone by a string. The system can be autonomous, controlled by a ground-based human pilot, or a combination of the two.
