An alternative has been developed to direct measurement for determining the density of the atmosphere of the Saturn moon Titan as a function of altitude. The basic idea is to deduce the density versus altitude from telemetric data indicative of the effects of aerodynamic torques on the...

Many atmospheric research aircraft use a standard canister design to mount instruments, as this significantly facilitates their electrical and mechanical integration and thereby reduces cost. Based on more than 30 years of airborne science experience with the Microwave...

A collection of documents provides further detailed information about an optoelectronic instrument that measures the pH of an aqueous cell-culture medium to within ±0.1 unit in the range from 6.5 to 7.5. The instrument at an earlier stage of development was reported in “Optoelectronic Instrument Monitors...

A report discusses the development of a Mars surface, laboratory-based solar simulator to create solar cells that can function better on Mars. The Mars Optimized Solar cell Technology (MOST) required defining the surface incident spectrum, developing an appropriate laboratory solar...

VESGEN is a newly automated, userinteractive program that maps and quantifies the effects of vascular therapeutics and regulators on microvascular form and function. VESGEN analyzes two-dimensional, black and white vascular images by measuring important vessel morphology...

To reject solar radiation photons at the front aperture for large telescopes, a mosaic of large transmission mode filters is placed in front of the telescope or at the aperture of the dome. Filtering options for effective rejection of sunlight include a smaller filter down-path near the focus of the...

SiGe is an important semiconductor alloy for high-speed field effect transistors (FETs), high-temperature thermoelectric devices, photovoltaic solar cells, and photon detectors. The growth of SiGe layer is difficult because SiGe alloys have different lattice constants...

PYROFAST is a needle-free injection system with pyrotechnical gas propulsion that provides accurate and comfortable drug delivery through the skin for intra-dermal, subcutaneous, and intra-muscular injections of liquid and solid (lyophilized) drugs. The needle-free injection occurs within...

EU RoHS, China RoHS, Korea RoHS, California RoHS, ELV, REACH – the list of environmental regulations for reducing hazardous substances in products keeps growing. What, exactly, are the costs if your products fail to comply? Missed customer requirements, blocked shipments, costly redesigns, and scrapped parts are...
