Techshot, Inc. proposes continued research and development of an on-orbit cell counter culminating in a deliverable hand-held blood cell counter in the form of a "Microfluidic Multichannel Flow Cytometer". Crew health monitoring, the Human Research Program and research in Fundamental Biology will all benefit from the availability of on-orbit cell counters that can provide immediate and repeated b ...

Recovery of water from brine is critically important for future manned space exploration. Resupply of water is prohibitively costly for such extended missions. Water reclamation processes typically recover 90-95% of the water present in wastewater formed by combining urine, hygiene water, and humidity condensate with the remaining concentrated in brine. This concentrated brine contains a signif ...

A back-illuminated planar InGaAs photodiode tested to have 95% quantum effiiency (QE) at 1550 nm, area greater than 1 mm2, low capacitance (125 MHz) will be improved. Although the existing Phase I device exhibited bulk material dark current generation better than commercially available devices, the sidewall-generated dark current was found to dominate the noise equiva ...

This Phase II SBIR project will continue the development of an optical sorter that will be used to estimate drop sizes in sprays. The optical sorter will determine the size of drops in the 0.1 to 10 microns range. Drops in this size range are prevalent in the automobile industry, where the fuel injection pressures have increased tremendously over the past two decades. These newer injectors provide ...

A hollow reservoir cathode for use in ion and Hall thrusters which uses iodine as propellant. Reservoir cathodes have unique features not found in conventional impregnated cathodes. The critical barium reduction process occurs in the reservoir, not in the matrix, and this isolates that process from iodine poisoning. Also, the barium supply is 100 times greater than is available in conventional cat ...

For the purposes of supporting planned and future NASA missions and addressing an unmet NASA need for high-quality visible through shortwave-infrared telescope phase-correction optics manufactured and delivered quickly and inexpensively, Voxtel proposes a Phase II effort to develop a new class of three-dimensional freeform optics and to demonstrate the optical precision and size reduction possible ...

The nondestructivecharacterization of advanced composites, such ascarbon-fiber reinforced polymers (cfrp), by electromagnetic means iswell established [6]-[24]. What isneeded to advance the state of the art are sophisticated inversionalgorithms that allow layup and impact damage to be determined inlocalized regions, which means that the more traditional methods ofmodel-based inverse methods must ...

According to the decadal report titled, Life and Physical Sciences Research for a New Era of Space Exploration, a Report, "...the AHB Panel would be remiss if it did not strongly recommend an animal centrifuge capable of accommodating rats/mice at variable gravity levels." Furthermore, the panel stated, “...research on animal models will be constrained without the ability to manipulate the gravi ...

This SBIR system is a machine learning system that uses a very large database of airside and landside data to predict pushback and takeoff times of aircraft at a given airport. Airside data sources describe the state of the system after TSA security screening is complete, and includes information about the crew and passengers arriving at the departure gate, turnaround and pushback preparation, ra ...

Automatic Dependent Surveillance - Broadcast (ADS-B) has been mandated by the FAA for all aircraft that fly in Class A airspace in year 2020 and beyond. ADS-B will be the foundation of surveillance, and in this SBIR effort, we exploit the fact thta ADS-B data can also provide evidence of aircraft flying through known sources of aviation turbulence. Phase I R&D showed that moderate or greater leve ...
