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.

A display system for a vehicle includes a navigation database storing navigation data; a terrain sensor configured to gather terrain data; a processor adapted to receive the navigation data and the terrain data and operable to supply one or more image rendering display commands based upon the navigation data and the terrain data; and a display device. The display device is coupled to receive the image rendering display commands and operable, in response thereto, to render (i) a perspective view image representative of the terrain data and the navigation data and including terrain and (ii) at least one line on the perspective view image that extends at least partially across the terrain and represents at least one of a ground-referenced range to a fixed location on the terrain and a vehicle-referenced range from the vehicle to a fixed range away from the vehicle.

An aircraft synthetic vision system (100) is provided for increasing data input to a pilot (109) during approach and landing flight operations, and includes a runway assistance landing system (114) and a plurality of databases (106, 108, 110, 112) which may include, for example, a terrain database (106), an obstacle database (112); and a validated runway database (110). The processor (104) detects the likelihood of an error in determining the altitude from at least one of the runway assistance landing system (114), the plurality of databases (106, 108, 110, 112), and identifies the error. The processor (104) further determines augmented coordinates, and a processor (104) generates symbology commands to a first display (116) for displaying a runway environment in response to data provided to the processor (104) from each of the runway assistance landing system (114), the plurality of databases (106, 108, 110, 112), and the processor (104).

Embodiments of the invention generally relate to epitaxial lift off (ELO) thin films and devices and methods used to form such films and devices. In one embodiment, a method for forming a thin film material during an epitaxial lift off process is provided which includes forming an epitaxial material over a sacrificial layer on a substrate, adhering a non-uniform support handle onto the epitaxial material, and removing the sacrificial layer during an etching process. The etching process further includes peeling the epitaxial material from the substrate while forming an etch crevice therebetween and bending the support handle to form compression in the epitaxial material during the etching process. In one example, the non-uniform support handle contains a wax film having a varying thickness.

A system and method for displaying aircraft glide slope includes determining a glide slope deviation that is representative of a difference between a desired aircraft glide slope and an actual aircraft glide slope. A glide slope icon that is representative of the desired aircraft glide slope and a glide slope deviation icon that is representative of the determined glide slope deviation are simultaneously rendered on a display.

A method of dynamically displaying lateral deviation in formats on a display is provided. The method comprises assigning one or more positional boundaries for displaying the lateral deviation information, wherein the one or more positional boundaries define areas on a display. The method also comprises calculating display positions of a lateral deviation symbology and determining if each calculated display position is allowed based on where the lateral deviation display would be located, if displayed at each calculated position, in relation to the one or more positional boundaries. The method further comprises, displaying the lateral deviation symbology at the calculated positions when the calculated positions are allowed, and displaying a lateral deviation indicator when the calculated positions are not allowed.

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.
