Although suited astronauts are currently cooled with a Liquid Cooled Ventilation Garment (LCVG), which can remove up to 85 percent of body heat, their effectiveness is limited because cooling must penetrate layers of skin, muscle, fat, bone, and tissue to reach the bloodstream, where its...

This invention relates to surface modification of porosified silicon (pSi) structures with poly(alkylene) glycols for the purpose of controlled degradation of the silicon matrix and tailored release of encapsulated substances for biomedical applications. The pSi structures are currently...

A microshutter array (MSA) has been developed for use as an aperture array for multi-object selections in James Webb Space Telescope (JWST) technology. Light shields, molybdenum nitride (MoN) coating on shutters, and aluminum/ aluminum oxide coatings on interior walls are put on each shutter for...

Hall thrusters utilize identical hollow cathode technology as ion thrusters, yet must operate at much higher mass flow rates in order to efficiently couple to the bulk plasma discharge. Higher flow rates are necessary in order to provide enough neutral collisions to transport electrons across magnetic fields so...

This week's Question: The European Organization for Nuclear Research, or CERN, reported that a neutrino beam fired from a particle accelerator near Geneva to a lab 454 miles away in Italy traveled 60 nanoseconds faster than the speed of light — a claim that potentially questions Einstein's 1905 special...

Boeing (Everett, WA) has delivered the first 787 Dreamliner to Japan's All Nippon Airways (ANA). The 787 Dreamliner is an all-new airplane featuring a host of technologies that benefit both airlines and passengers. It is the first mid-size airplane capable of flying long-range routes, enabling...

Marlow Industries (Dallas, TX) has introduced the EverGen series of thermoelectric-based energy harvesting devices, offering a zero-maintenance power solution for wireless sensor applications. EverGen thermal energy harvesters power wireless sensors without a battery, reducing replacement...

Two types of design tests for relays and relay systems that relate to the immunity of this equipment to repetitive electrical transients are specified. Test generator characteristics, test waveforms, selection of equipment terminals on which...

A conceptual design has been developed for a miniature laser magnetometer (MLM) that will measure the scalar magnitude and vector components of near-Earth magnetic fields. The MLM incorporates a number of technical innovations to achieve high-accuracy and high-resolution performance while significantly reducing the size...

The particle fallout limitations and periodic allocations for the James Webb Space Telescope are very stringent. Standard prediction methods are complicated by non-linearity and monitoring methods that are insufficiently responsive. A method for dynamically predicting the...
