This program will develop and calibrate an electronc sensor to verify the partial pressure of oxygen actually being delivered to aircrews at both high and low altitudes. it will read out continuously and in real timeand can be set to trigger an alarm if the oxygen partial pressure varies outside… More

Municipal waste treatment produces sludges rich in complex organic chemicals that should be considered as a chemical raw material and resource analogous to wood pulp, ag agricultural wastes, or petroleum. current disposal p practices of landfilling, ocean disposal and even incinerar ation disregard… More

The vapor space inside an aircraft fuel tank either is or is not flammable (or explosive) depending upon the percentage of fuel vapor and of oxygen of inert gas such as nitrogen or carbon dioxide. it is important to know these percentages when testing the efficacy of experimental inerting measures… More

A requirement exists to provide ocular protection to troops at risk from laser energy exposure and ballistic fragments while maintaining essential visual performance. since hostile laser beams may be at unexpected wavelengths, the usual notch filter is not a complete answer to the problem. this… More

A requirement exists to provide ocular protection to troops at risk from laser energy exposure and ballistic fragements while maintaining essential visual performance. optical filters based on holographic mirrors or thin film interference filters are effective in blocking laser beams but are fragile… More

The color filters currently used to convert black-and-white lcd displays to color displays severely limit the brightness of the displays because available color filter materials (dyes and glasses) are inherrently rather broadband. consequently, if they are dense enough to limit the transmitted light… More
