A medication delivery apparatus and method for a continuous positive airway pressure (CPAP) system such as used in emergency treatment of severe respiratory distress. The apparatus of the invention includes a 3-port Tee fitting, one port of which is connected to the inlet port of a CPAP face mask operable at an elevated pressure. A second port is connected to a CPAP gas conduit supplying an oxygen-containing gas at a pressure above atmospheric. The third port is connected to a flexible tube receiving aerosolized medication from an upper outlet of an openable/refillable lightweight nebulizer. The flexible tubing is only long enough to bend vertically downward to support a lightweight nebulizer in a vertical attitude, whereby full nebulization takes place, no medication is spilled, and the tubing length is minimized for maximal transfer of medication to a patient. In addition, cutting of the CPAP gas supply tube and placement of a T fitting between the cut ends, with its concomitant wastage of condensed medication, is avoided. The patient head does not need to be in an upright position. The patient's airway is continuously maintained at an elevated pressure to maintain an open airway and oxygenate the patient, permitting repeated doses of nebulized medications at independently controlled nebulization rates, minimizing downtime of both the pressurized oxygen and aerosolized medication.

A new class of algorithms has been developed to estimate spectral reflectance in remote sensing imagery. These algorithms are called Surface Prior Information Reflectance Estimation (SPIRE) algorithms and estimate surface spectral reflectance using prior spatial and spectral information about the surface reflectance. This paper describes SPIRE algorithms that employ spatial processing of single channel data to estimate local changes in spectral reflectance under spatially and spectrally varying multiplicative and additive noise caused by variations in illumination and atmospheric effects. Rather than modeling the physics of the atmosphere and illumination (using a physics-based code such as ATREM), or using ground truth spectra at known locations to compensate for these effects (using the Empirical Line Method), prior information about the low spatial frequency content of the scene in each spectral channel is used instead. HYDICE VNIR-SWIR hyperspectral data were used to compare the performance of SPIRE, ATREM, and ELM atmospheric compensation algorithms. The Spatial SPIRE algorithm performance was found to be nearly identical to the ELM ground-truth based results, while Spatial SPIRE performed better than ATREM overall, and significantly better under high clouds and haze.

A high-energy laser weapon system in which the high-energy laser beam itself is used to correct for atmospheric fluctuations thereby replacing a separate beacon illuminator system. The high-energy laser is turned off (negative pulse) periodically for a very short period giving a wavefront sensor an opportunity to measure the return of the high-energy laser beam from the target. A wavefront sensor drives a deformable mirror based on this return signal avoiding wavelength anisoplanatism. In addition, the high-energy laser weapon can be snapped ahead of the path of the target during the negative pulse to avoid tilt anisoplanitism.
