Reconfigurable Electronics and Non-Volatile Memory Research

Investigating ways to make non-volatile memory devices smaller, lower power, more reliable, and radiation tolerant.The purpose of this research was to investigate non-volatile memory device technologies that could be applied to reconfigurable electronics applications to provide power reduction, radiation tolerance, smaller size, and improved reliability over existing non-volatile memory devices. The research encompasses: 1) materials and device design, and 2) fabrication and testing of the devices. The types of memory devices that were investigated are divided into three categories:

Energy-Filtered Tunnel Transistor: A New Device Concept Toward Extremely Low Energy Consumption Electronics

Device used to study energy-filtered cold electron transport at room temperature: (a) The device structure. (b) Energy diagram for energy-filtered cold electron transport. The quantum well is formed in the conduction band of the Cr203 layer through band bending and a quantum well state serves as an energy filter. Altering the thermal characteristics of semiconductors can prolong battery life.Excessive heat dissipation (or power consumption) of modem integrated circuits is an undesirable effect that imposes substantial limitations on the performance of many electronic devices. For example, the level of heat dissipation /power consumption of smart phones, tablets, and laptops is such that it prohibits a continuous and prolonged operation of these devices, requiring frequent recharging. Large power consumption of electronic devices requires large energy storage in batteries, increasing the battery weights that soldiers carry in their missions or the weights of remote controlled equipment such as unmanned aerial vehicles (UAVs). Therefore, technology that enables electronic devices to operate with extremely small energy consumption promises a broad range of commercial, military and space applications.

Simulation Software Improves Pilot Training

Simulation of a helicopter landing on a ship. (Chair of Helicopter Technology/TUM) Providing pilots with the best possible preparation for extreme situations is the goal of new simulation software. The program that combines flow mechanics and flight dynamics in real time. The numerical model is extremely flexible and does not depend on stored flow data. External conditions such as topography, global wind speeds, and aircraft type are input. During the simulation, the algorithms use that data to continuously compute the interacting flow field at the virtual aircraft’s current location.

High-Speed, Autonomous Surface Patrol Capability Demonstrated

A successful demonstration by Johns Hopkins APL and the Surface Targets Branch of the Naval Air Warfare Center Weapons Division involved six surface target boats operating together at high speeds, using hardware and software that APL developed and integrated with the reliable boat control system created by the Surface Targets Branch. (Photo: U.S. Navy/JHUAPL) After a year of internal research and development, the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, recently conducted a large, at-sea demonstration of swarming unmanned surface vessels (USV). The experiment — done in collaboration with the Surface Targets Branch of the Naval Air Warfare Center Weapons Division, Port Hueneme, California — was designed to advance the state of the art of collaborative, autonomous USV behaviors to higher speeds and a larger numbers of vessels.

Army Researchers Demonstrate 3-D Printed Drones

The 3-D printed On-Demand Small Unmanned Aircraft System, or ODSUAS, flies at speeds of up to 55 miles per hour. Although the lightweight shell and propeller arms are printed using additive manufacturing, the motors and propellers will be assembled using off-the-shelf equipment. (Photo: Angie DePuydt) Soldiers witnessed the innovation of Army researchers recently during flight testing of 3-D printed unmanned aircraft systems that were created on-demand for specific missions.
