Title: High performance nozzle
Inventor: SHARKEY DOUGLAS ALLAN
IPC: A62C31/02
Filed: 2004-06-03
Abstract: What is new about this nozzle is its ability to extend the reach of a fluid stream from a pressurized hose by means of low-friction design and nozzle aperture extension. The combination of low friction design and aperture extension produces an effect which is superior to that which might be anticipated by adding an extension to a hose. The nozzle is made of strong, lightweight, rigid materials. The extended stream reach exceeds the length of the long nozzle itself.

Filed: 2003-04-03
Abstract: L'invention concerne un procédé et un système permettant d'éliminer des contaminants de traitement animal ainsi que des huiles et des graisses, de grands volumes d'eaux usées. Dans ce procédé, un flux d'eaux usées contenant des contaminants est traité à l'aide d'un composé polymère oxydant chimique et d'un coagulant pour créer une particule présentant un diamètre supérieur à 50 microns. Les eaux usées traitées passent à travers une membrane de microfiltration qui sépare physiquement la particule de contaminant des eaux usées. Des membranes de microfiltration disponibles dans le commerce, présentant une taille de pore comprise entre 0,5 et 10 microns, peuvent être utilisées. Le débit des eaux usées traitées à travers les membranes de microfiltration peut aller d'au moins 200 gallons par pied carré de membrane par jour (<= GFD >=) à plus de 750 GFD. Les solides sont éliminés de la surface membranaire par circulation inverse périodique des membranes de filtration et par le drainage de la cuve de filtration à l'intérieur de laquelle sont situées lesdites membranes. La matière solide délogée à l'intérieur de la cuve de filtration est évacuée dans un réservoir de maintien pour un traitement ultérieur des solides. Le produit de déchet solide peut être incorporé à des produits à consommer par une espèce différente.

Title: Methods and apparatus for providing context and experience sensitive help in voice applications
Inventor: COOPER ROBERT S
IPC: G10L15/26
Filed: 2005-01-18
Abstract: Systems and techniques for improved user prompting in the event of voice recognition failures. A system according to one aspect of the invention includes a central server hosting various modules employing voice recognition in order to interpret user inputs. When a module fails to recognize an input, it invokes a help application that selects an appropriate help prompt. The help application has access to user information including information indicating the user's experience with each function of each module. The help application receives notification of the module and function being used when the unrecognized input was received and examines the user information to determine the user's experience with the module and function. The help application categorizes a user as belonging to an experience category, such as novice, intermediate and expert based on the user's experience with the function and selects a help prompt associated with the user's experience with the function.

IPC: G09G3/32
Filed: 2003-09-09
Abstract: A display for an electronic device may be calibrated and corrected for pixel-to-pixel variations in intensity. Radiation-sensing elements used for the calibration are not incorporated as circuit elements within the pixel circuits and may lie outside the pixels. Waveguides, reflectors, or the like may be used to optically couple the radiation-emitting elements of the pixels to the radiation-sensing elements.
