Performance Characteristics of Digital Frequency Discriminators

Digital frequency discriminators are key components of instantaneous frequency measurement (IFM) receiver systems as well as many other complex electronic warfare (EW) systems. However, to obtain optimum results it is essential to match DFD performance levels to a specific application. DFDs are integral components of IFM receiver systems; they may also be imbedded into a wide range of military systems such as radar warning receivers (RWRs), electronic countermeasures (ECM) systems, and electronic support measures (ESM) platforms, where they help provide instantaneous frequency measurement capability.

Thermal Management Solutions for Medical Applications

Thermoelectric Assemblies (TEAs) offer precise temperature control for applications with tight space constraints and low weight requirements. Thermal management of medical electronic devices and systems is now more challenging. Power densities continue to increase while product form factors continue to shrink. Simple thermal management solutions, such as passive cooling (adding a fan and heat sink), are no longer typically viable to meet required performance and reliability specifications. In today’s complex medical operating environment, Thermo electric Assemblies (TEAs) are necessary to provide precise temperature control via cooling and heating in a variety of modular platforms.

Hybrid Solar System For Rooftop Hydrogen

Instead of systems based on standard solar panels, Duke University engineer Nico Hotz proposes a hybrid option in which sunlight heats a combination of water and methanol in a maze of glass tubes on a rooftop. After two catalytic reactions, the system produces hydrogen that can be stored and used on demand in fuel cells.
