Abstract: A stable ophthalmic pharmaceutical composition for relief, treatment, control, alleviation, or prevention of a pathological ocular condition of the eye comprises: (a) a first polymer, a viscosity of which changes with a change in a concentration of an electrolyte, such as a salt, when added to said first polymer; (b) a second polymer that is different from the first polymer and can modify the viscosity of the first polymer; and (c) an oil. In some embodiments, the composition further comprises a non-ionic surfactant. The composition can form a stable oil-in-water emulsion on storage, but separate into an oil phase and a water phase when applied in the eye. The emulsion can comprises an ophthalmic active pharmaceutical ingredient dissolved in the oil or water phase. The emulsion can provide enhanced stability to said active pharmaceutical ingredient.

Abstract: A composition for providing relief to a discomfort of an eye comprises a pharmaceutically acceptable carrier and a polysaccharide extracted from a plant source. In certain embodiments, such a polysaccharide can be extracted from mushrooms, such as from the Tremella fuciformis species. The composition is administered to an affected eye to provide such relief or discomfort.

Abstract: A real-time data management system which uses data generated at different rates, by multiple heterogeneous incompatible data sources. In one embodiment, the invention is as an airport surface traffic data management system (traffic adviser) that electronically interconnects air traffic control, airline, and airport operations user communities to facilitate information sharing and improve taxi queuing. The system uses an expert system to fuse data from a variety of airline, airport operations, ramp control, and air traffic control sources, in order to establish, predict, and update reference data values for every aircraft surface operation.

Abstract: A data management system and method that enables acquisition, integration and management of real-time data generated at different rates, by multiple, heterogeneous incompatible data sources. The system achieves this functionality by using an expert system to fuse data from a variety of airline, airport operations, ramp control, and air traffic control tower sources, to establish and update reference data values for every aircraft surface operation. The system may be configured as a real-time airport surface traffic management system (TMS) that electronically interconnects air traffic control, airline data and airport operations data to facilitate information sharing and improve taxi queuing. In the TMS operational mode, empirical data shows substantial benefits in ramp operations for airlines, reducing departure taxi times by about one minute per aircraft in operational use, translating as $12 to $15 million per year savings to airlines at the Atlanta, Georgia airport.
