Abstract: Design software in accordance with an implementation of the present invention is configured to provide believable three-dimensional representations of user selections in real-time.  Design elements that would otherwise be difficult to efficiently render three-dimensionally in real-time are prerendered for realistic visual effects, such as realistic shading, which correspond to various positions of the elements in a design space. Blanks of the visual effects for each position an then stored in a data store for visual effects. At run time, data associated with user design choices, as well as the blanks for any corresponding design elements are fed in one implementation to peripheral. processing hardware, such as a GPU, which sends the processed data to a display device. The user is therefore able to view complex visual data of certain design choices efficiently with added realism.

Title: Measurement of vaporized h2o2 using near infrared spectroscopy for sterilization
Inventor: TODD TERRY R
IPC: G01N21/3504
Filed: 1996-05-21
Abstract: Measurements of concentrations of hydrogen peroxide vapor in the presence of water vapor is made using near infrared (NIR) spectroscopy with fiber optic cables to transmit infrared radiation between, e.g, a sterilization chamber and the NIR  instrument.  Hydrogen peroxide absorbs selectively at about 1420 nm, where water vapor also absorbs, but the absorbance at 1420 nm can be corrected for water vapor measurements at remote wavelengths where H202 is transparent. The measurement process also may be incorporated into a control system assuring optimum hydrogen peroxide vapor concentrations for the sterilization procedure.

Title: Method and apparatus for directional drilling with variable drill string rotation
Inventor: HAMILTON JAMES F
IPC: E21B7/04
Filed: 2007-09-06
Abstract: Apparatus and methodology is provided for directional drilling which avoid the effects of static friction between the drill string and the borehole. The drill string is rotated continuously in one direction during rotating drilling and during steering. During steering, the rotary speed of the drill string is varied within a revolution and substantially similarly for each of a plurality of subsequent revolutions. The drill string is be rotated very slowly when oriented at or near the desired orientation to achieve the desired change in direction and then rotated much faster during the balance of each revolution. This angular velocity profile results in drilling at or near a desired orientation for a high percentage of the time it takes for each revolution. Changes in an effective tool-face orientation can be effected by shifting the phase of the velocity profile.
