Loop Thermosyphons

Two-phase cooling has been utilized in the electronics cooling industry for many decades, with possibly the most well-known adaptation being the heat pipe. Heat pipes are capillary-driven, two-phase devices that rely on the boiling and condensation of a working fluid to transfer heat significant distances with minimal temperature gradient. The flow of the working fluid inside of a heat pipe is facilitated by a capillary wick structure that relies on surface tension to return the condensed liquid to the heat generating components. Heat pipes have found their way into a large number of industries and applications because of their high performance, high reliability, and low cost. Unfortunately, as the electronics industry’s insatiable quest for smaller, higher-powered devices soldiers on, the discrete cooling power of the heat pipe approaches obsolescence.

CompactPCI Serial Space

There are a few open specifications in the embedded industry that have been used in the extreme environments of space over the years. These include VME, CompactPCI, OpenVPX, and MicroTCA. But, prime contractors such as Airbus and others desired a high performance and versatile architecture that was relatively simple and cost-effective. The CompactPCI Serial Space specification was ratified in 2017 to address these requirements, resulting in a compelling architecture for defense and space-based projects.

Designing With MIL-STD-1553B Components

The interconnected backbone of a MIL-STD-1553B vehicle depends on the electrical and mechanical reliability of the components, the design, and the installation. With the vast array of MIL-STD-1553B specified sub-assemblies, there are factors that can go overlooked for passive components such as couplers, cables, and connectors. Often built with kilometers of wiring, aircraft in particular can be difficult to troubleshoot and must be inspected frequently for potential failures such as intermittent connections, shorts, and corrosion. Still, these passive components that make up the network can be individually assessed to operate with a high level of integrity.

University Researchers Give Self-Driving Vehicles a Boost

While the future of vehicles may be driverless, West Virginia University is steering the technology in the right direction. More and more cars being sold today include semi-automated features ranging from self-parking to lane departure to automatic braking, but fully automated vehicles are on the horizon. WVU’s researchers are working to improve vehicle and smart infrastructure technology that underpins their development and their benefit to communities in areas such as safety, energy, traffic, economic opportunity and more. One of those researchers is Victor Fragoso, an assistant professor in the Lane Department of Computer Science and Electrical Engineering, whose research is focused on improving the artificial intelligence of autonomous agents, which includes driverless vehicles.

Antenna Basics

The antenna is the most intrinsic component of all RF systems, yet the principles of antenna design and wave propagation are rarely discussed outside the entry level engineering classes. Rohde & Schwarz has developed an educational white paper on Antenna Basics to reteach the basic principles in a simplified manner.

Sensitivity Simulation of Compressed Sensing Based Electronic Warfare Receiver Using Orthogonal Matching Pursuit Algorithm

Electronic Intelligence Receiver (ELINT) is an important component in electronic warfare (EW) and layer sensing. The information it provides by constant surveillance can be used to detect, track and classify signals across the electromagnetic spectrum. The proper identification and reaction to the threat can avoid disaster and assure spectrum dominance for Air Force systems.
