Abstract: A head-mounted display includes two sets of mirrors. The head-mounted display also includes a rigid structure. The rigid structure supports an image source and supports the two sets of mirrors. The apparatus is worn on the head of a user. Each mirror set comprises three or more curved mirrors. In some cases, each set of mirrors includes a mirror at cheek level, a mirror at brow level, and a mirror in front of an eye. For each mirror set, light travels from the cheek mirror, to the brow mirror, to the mirror in front of the eye. Each set of mirrors rotates an image displayed by the image source and relays the image to an eye of the user. The image undergoes a net rotation of substantially ninety degrees between the image source and the eye.

Abstract: The disclosure relates to a process for making titanium dioxide, comprising: reacting titanium tetrachloride with oxygen by contacting the titanium tetrachloride with the oxygen in a vapor phase reactor under mixing conditions and at an elevated temperature to form a gaseous product stream containing titanium dioxide; separating the titanium dioxide from the gaseous product stream to form a process stream; analyzing the process stream to detect a concentration of titanium tetrachloride in the process stream; comparing the concentration of titanium tetrachloride detected in the process stream to an aim point concentration; and modifying the oxidation conditions to restore or maintain the concentration of titanium tetrachloride in the process stream at the aim point.

Abstract: A computer system may include a display and a user interface selection device. The computer system may display a first set of data associated with a first index of a data store in a first frame, and may receive a first selection signal indicative of the user interface selection device selecting a first item of the first set of data. In response to the first selection signal, the computer system may retrieve a second set of data from the data store associated with a second index of the data store, the second set of data being associated with the first item. The computer system may display the second set of data in a second frame distinct from the first frame.

Abstract: A system and method for low impact backup. In one embodiment, a method may comprise monitoring utilization of a system resource and a data management process selectively performing I/O operations dependent upon the monitored utilization of the system resource. The data management process may include functionality to backup desired data from a storage medium to a backup medium. In one particular implementation, the I/O operations may be allowed to be performed in response to the utilization of the system resource falling below a predetermined threshold. In another embodiment a method may comprise performing a plurality of I/O operations to complete a data management process executed by an application. The application separates said plurality of I/O operations with intermittent delays to achieve time-slicing of the data management process with respect to one or more other applications.

Abstract: A graphical user interface (GUI) is presented on a display including a parent window and a number of child windows rendered within the parent window according to a display scheme. When the size of one of the child windows is changed, the size of one or more of the other child windows is changed, so that the display scheme is maintained.

Abstract: Help functionality is described for integrating help information into a primary application in a just-in-time fashion. The help functionality can perform this task by providing a see-through panel which is presented on top of an application interface provided by the primary application. A user can move a mark on the see-through panel to identify features of the application interface concerning which he or she may have questions. The help functionality responds by presenting potentially context-sensitive help information to the user in audio mode and/or visual mode. If the visual mode is selected, the help functionality can present the help information on the see-through panel itself, and/or can dynamically move parts of the application interface to accommodate the display of the help information. The help functionality can supply the help information from a local source and/or a remote source, in an automated manner and/or a manual manner (e.g., using a remote human assistant).

Abstract: This invention provides a laser trimming method for tuning the frequency of a spiral resonator, and for improving the characteristics of a high temperature superconductor filter comprised of high temperature superconductor spiral resonators, by tuning the individual high temperature superconductor spiral resonators. This invention also provides a method for tuning the resonance frequency of a high temperature superconductor planar coil. This invention also provides a laser ablation process for creating high temperature superconductor circuit elements.

Abstract: A method for producing periodic nanometer-scale arrays of metal or semiconductor junctions on a clean semiconductor substrate surface is provided comprising the steps of: etching the substrate surface to make it hydrophilic, forming, under an inert atmosphere, a crystalline colloid layer on the substrate surface, depositing a metal or semiconductor material through the colloid layer onto the surface of the substrate, and removing the colloid from the substrate surface. The colloid layer is grown on the clean semiconductor surface by withdrawing the semiconductor substrate from a sol of colloid particles.

Abstract: A personal mobility vehicle having an accessory power system includes a drive wheel, an electric motor coupled to the drive wheel, a main power source connected to the motor, and an accessory power source energized by the main power source. The accessory power source provides an accessory output at a voltage that is independent of fluctuations in the voltage supplied by the main power source.
