For more than a decade, engineers have been eyeing the finish line in the race to shrink the size of components in integrated circuits. They knew that the laws of physics had set a 5-nanometer threshold on the size of transistor gates among conventional semiconductors, about one-quarter the size of high-end 20-nanometer-gate transistors now on the market. But some laws are made to be broken, or at least challenged.

# T-rays Will “Speed Up” Computer Memory By a Factor of 1,000

The figure shows the spin and lattice structure of thulium orthoferrite (TmFeO₃) on the left and the T-ray-induced transitions between the energy levels of thulium ions (Tm³⁺), which trigger coherent spin dynamics (memory switching), on the right.

Together with their colleagues from Germany and the Netherlands, scientists at the Moscow Institute of Physics and Technology (MIPT) have found a way to significantly improve computer performance. They propose the use of so-called T-waves – or terahertz radiation – as a means of resetting computer memory cells. This process is several thousand times faster than magnetic-field-induced switching.

Our improvements to data handling and compression will hopefully go on to save many lives in the future. This award will help garner the attention of potential licensees and build interest in this advancement. We are very grateful to NASA Tech Briefs and the judges for their consideration.” This NASA-developed data-compression technology is capable of encoding massive amounts of data into a package more than 1,000 times smaller than with standard compression, which can transform the use of digital terrain maps (DTMs) in restricted environments such as tablets, smartphones, and embedded systems. Created at NASA’s Armstrong Flight Research Center, the software system integrates innovative encoding and decoding algorithms to provide a 5,000:1 compression ratio and rapid/continuous decompression in constrained computing situations. It enables users to access and create customized DTMs from a variety of data sources using a single graphical user interface.

Part of the increased demand is due to an aging population with more chronic conditions. These smaller portable units requires devices with smaller footprints. By the same token, smaller devices need to provide adequate levels of care to ensure patient safety and comfort. Thus, functionality cannot be sacrificed for space.

# Developing and Testing Electronic Control Units for Electric Drives

Air framers are looking to build more eco-friendly and economical aircraft, and they are turning to electric drives. One growing trend is to build more electrical aircraft by replacing pneumatic and hydraulic systems with electric actuators. Electric drives, therefore, will play an important role in the aircraft of the future. This paper examines the current state of technology for developing and testing electric drives.

# A High-Efficiency Power Module

Innovators at NASA’s Glenn Research Center have developed a microwave power module to power radar, communications, and/or navigation interchangeably. This high-efficiency, all-solid-state microwave power module (MPM) is based on a multi-stage distributed-amplifier design, which is capable of very wideband operation. This MPM is extremely durable and can last a decade or longer. Already more compact and lightweight than conventional designs, Glenn’s patented technique offers further size reduction by eliminating the need for either a traveling-wave tube amplifier or its accompanying kV-class electronic power conditioner. The performance of this MPM is exceptional, with much higher cut-off frequency and maximum frequency of oscillation than metal-semiconductor field-effect transistors offer, and the distributed amplifier’s wide bandwidth also results in much faster pulse rise times. Finally, Glenn’s design allows the module to operate in both pulsed and continuous wave modes, so it can single-handedly drive exceptional performance for radar, navigation, and communications.
