Abstract: A near-eye display includes a display configured to display images, a memory device storing a compensation profile for compensating perceived brightness nonuniformity (e.g., brightness roll-off) of the display, and a display controller for controlling operations of the display. The compensation profile includes compensation values for modifying brightness in regions of the display to compensate the perceived brightness nonuniformity. The display controller is configured to control brightness of the display based on the compensation profile.

Abstract: An exoscope with enhanced depth of field imaging is provided. The exoscope includes first and second sets of optical devices, the first set having a fixed image plane, the second set having a variable image plane adjacent the fixed image plane of the first set. The second set includes at least one variable device configured to change the position of the variable image plane. A beamsplitter splits light from a combined optical path of the first and second set to respective image devices of the first and second set of optical devices. A controller controls the at least one variable device to change the position of the variable image plane relative to the fixed image plane, combines images acquired by the respective image devices, and controls a display device to render a combined image.

Abstract: Methods and systems for controlling a surgical microscope. Moveable optics of the surgical microscope are controlled using two sets of control parameters, to reduce jitter and image instability. Shifts in the image due to changes in temperature or due to the use of optical filter can also be compensated. Misalignment between the mechanical axis and the optical axis of the surgical microscope can also be corrected.

Abstract: The invention provides compositions and methods for modulating GDP-L-Galactose Guanyltransferase (also known as GDP-L-Galactose phosphorylase) activity; and/or GDP-D-Mannose epimerase activity; and/or ascorbate content in plants. The invention provides plants and plant cells with increased GDP-L-Galactose Guanyltransferase activity; and/or GDP-D-Mannose epimerase activity. The invention provides plants and plant cells with increased ascorbate content as a result of: over-expression of GDP-L-Galactose Guanyltransferase; over-expression of GDP-D-Mannose epimerase; or in particular over-expression of a combination of GDP-L-Galactose Guanyltransferase and GDP-D-Mannose epimerase.

Abstract: A colored glass frit with a specific surface area of less than 2 square meters per gram that contains from about 1 to about 80 weight percent of metallic element material and from about 30 to about 80 mole percent of glassy network forming oxide material. The frit has a transmission density per micron of thickness of at least about 0.1; when formed into a continuous film of 3 microns thickness and deposited onto a glass substrate, its transmission density is at least 0.3. The glassy network forming oxide material is homogeneously disposed in the flit, and the metallic element material is inhomogeneously dispersed within the glassy network forming oxide material. The metallic element material is in particulate form and has a particle size distribution such that at least 95 weight percent of its particles are smaller than 300 nanometers.

Abstract: An omni-directional aircraft with flight capabilities surpassing those of a regular VTOL or helicopter, being able to take full advantage of the simultaneous six degrees of freedom of motion possible in the atmosphere, undergoing any desired combination of translational and rotational movement, and keeping station in the air in any arbitrary attitude. In the preferred embodiment, the flying object comprises a cubic body on the six faces of which are mounted six propulsion units, such that the propellers on each pair of opposite faces are coplanar with each other and with the main axis passing through the centers of these opposite faces, and their thrusts act along the direction of another main axis, each of the three pairs of propellers acting along a different one of the cube's three main axes.

Abstract: A travel product inventory and rate management system includes a bulk inventory and rate database containing inventory and rate information related to individual travel products provided by a number of travel product suppliers The system can include a component bundler that selectively chooses at least two of the plurality of individual travel products and combines them into a vacation package. The system has a connection to a vacation package seller allowing the vacation package seller to select and reserve the vacation package. The component bundler may be a dynamic component bundler that chooses the individual travel components and combines them into a vacation package at the time when the vacation package seller selects and reserves the vacation package or may choose the individual travel components and combine them into a vacation package prior to the time when the vacation package seller selects and reserves the vacation package.

Abstract: The described systems and methods are directed at configuring a server based on a selected role. An installation application is configured to install core components in a server where these core components enable the server to perform the basic functions of a network computing device. A role management application is configured to enable a system administrator to select a role for the server and to automatically determine software components associated with the selected role. The role management application is then configured to build the software components and install the components on the server. The role management application is further configured to configure the components for the selected role. The automated installation process performed by the role management application enables a server to be efficiently configured for a particular role without installing other unnecessary components unrelated to the role.
