    摘要： A polarization independent optical spectrum analyzer comprises a diffraction grating, input and output slit means and polarization-maintaining multi-pass optics for directing a light beam to and fro across the diffraction grating while maintaining its linear state of polarization. The optical spectrum analyzer further comprises a polarization control unit for decomposing a light beam for analysis into first and second beams having mutually orthogonal states of polarization (SOPs) and then adjusting one or both SOPs so that they are parallel to each other and to one of the dispersion plane of the diffraction grating which is rotated to select different wavelengths of the first and second light beams. The first and second light beams are passed across the diffraction grating repeatedly by multi-pass polarization-maintaining optics and are outputted and detected separately.

    摘要： Methods and apparatus are provided for interactively building flight paths for entry into an aircraft flight management system (FMS). The apparatus comprises a database containing map information, a display for presenting the map information, a user controlled cursor and selection buttons, all under the control of a graphics processor. The processor presents the map information with included navigation features on the display, correlated with the aircraft position and cursor location. When the cursor overlies a navigational feature (airways, waypoints, etc.), the processor highlights the feature. Feature ID information may also pop up when the feature is highlighted. Using a mouse button or equivalent, the user selects the highlighted feature or ID, whereupon the processor sends the information associated therewith to the FMS. By successively highlighting and selecting features or IDs an entire flight path can be identified and entered automatically into the FMS without the need for individual text entry.

    摘要： An on-line self-calibrating system where prior calibration information is updated by combining prior stored calibration information with current sensor reading information to simulate the introduction of a known calibrating sample and to generate new calibration information. A preferred embodiment of the present invention is in a laser spectral absorption system for determining the concentration of a particular gas in a gaseous sample by sensing a characteristic narrow spectral pulse in the absorption characteristics of the sample, the area or spectral integration of the pulse being proportional to the concentration of the particular gas. The disclosed technique effects on-line recalibration of the system based on current operating parameters of the system to compensate for time or usage induced degradation in system accuracy without introducing a sample of a known concentration of the gas into the system.

    摘要： Methods and apparatus are provided for converting electromagnetic radiation, such as solar energy, into electric energy with increased efficiency when compared to conventional solar cells. In one embodiment of a photovoltaic (PV) device, the PV device generally includes an n-doped layer and a p+-doped layer adjacent to the n-doped layer to form a p-n layer such that electric energy is created when electromagnetic radiation is absorbed by the p-n layer. The n-doped layer and the p+-doped layer may compose an absorber layer having a thickness less than 500 nm. Such a thin absorber layer may allow for greater efficiency and flexibility in PV devices when compared to conventional solar cells.
