One of the main heritage tools used in scientific and engineering data spectrum analysis is the Fourier Integral Transform and its high-performance digital equivalent — the Fast Fourier Transform (FFT). The Fourier view of nonlinear mechanics that has existed for...

The Lighting System to Improve Circadian Rhythm Control was designed and built to help regulate the sleep cycles of astronauts working on the International Space Station (ISS) and during long-duration spaceflight. In space, the lack of a...

High-intensity focused ultrasound (HIFU) is a rapidly developing medical technology that relies on focusing acoustic waves to treat remote tissue sites inside the body without damaging intervening tissues. HIFU can be used to treat benign and malignant tumors, dissolve blood...

A new method to screen the gastrointestinal (GI) tract for radiation sensitivity and radiation-induced gene damage has a number of applications. This technology could be used to assess radiation susceptibility in individuals, such as astronauts, nuclear reactor workers, those undergoing...

Supplemental oxygen delivery systems are vital to provide a critical life support respiratory function. Whether they are used for patients suffering from lung diseases or other illnesses, or astronauts donning an oxygen mask during a toxic spill or fire on a spacecraft, lightweight and portable...

The ability to distinguish between high and low levels of task engagement is important for detecting and preventing performance decrements during safety-critical operational tasks in the real world. Examples of such tasks include commercial aviation, monitoring for...

The microgravity conditions of space travel create unique physiological demands on the astronauts’ skeletal structures, resulting in a reduction in bone strength from restructuring of the micro-architecture and loss of key minerals. An ultrasound system was developed that is capable of...
