The complexity of aerospace and defense software has grown manyfold. For example, the U.S. Air Force F-22 Raptor jet fighter, consists of about 1.7 million lines of software code, while the F-35 joint strike fighter has about 5.7 million lines of code to operate its onboard systems. Boeing’s new 787 …

Free-space optical communication (FSO) is an optical communication technology that uses light propagating in free space to wirelessly transmit data for telecommunications or computer networking. “Free space” means air, outer space, vacuum, or something similar. FSO operates on the Line-of-Sight phenomenon, consisting of a LASER at source and detector at …

One of the most common functions in all electronic circuitry is switching. Switching has a wide range of uses. Engineers in industries ranging from telecommunications to military/aerospace need high-performance RF/microwave switching as part of their test setups. An RF switch or microwave switch is a device to route high frequency …

Neuroscience research promises huge benefits for the world. For countries with rapidly aging populations, advances in the field will be integral to managing and alleviating chronic pain, mental illness, and neurocognitive degenerative conditions such as dementia. Dementia alone was estimated to cost the United States as much as $215 billion …

UAVs have evolved into increasingly capable platforms deployed for a wide variety of applications. The capability to fight effectively in urban areas against widely dispersed forces, while minimizing collateral damage and achieving information superiority has enabled the UAVs to play a greater role in critical missions. The UAVs have become one …

Atmospheric balloons are balloons that are used for scientific research and meteorological observations. These balloons are typically large and made of materials that can withstand the high altitudes and extreme temperatures of the upper atmosphere. Atmospheric balloons are used to carry scientific instruments and equipment, such as cameras, sensors, …

Since fully autonomous UAS are still far off, the US Army has developed concept of Manned-unmanned teaming (MUM-T) for operation in A2/AD environments. Through MUM-T operations they expect to combine the strengths of manned and unmanned platform to increase situational awareness, allowing the armed forces to conduct operations that include …

A DC-to-DC converter is an electronic circuit or electromechanical device that converts a source of direct current (DC) from one voltage level to another. It is a type of electric power converter. Power levels range from very low (small batteries) to very high (high-voltage power transmission). In most of …
