Abstract: Systems, apparatus and methods are provided for the real-time positional manipulation of stereoscopic (3D) subtitles in a stereoscopic viewing environment. A stereoscopic subtitling workstation is provided for creating stereoscopic subtitling content for use with stereoscopic video content in which stereoscopic subtitling content can be manipulated and adjusted in real-time in a stereoscopic viewing environment to set the desired viewing position and appearance parameters for the stereoscopic subtitling content. The stereoscopic subtitling workstation may further automatically analyze the stereoscopic video content and automatically generate optimal viewing parameters for the stereoscopic subtitling content, including its 3D offset, according to desired appearances and interaction between such content. The automatically generated stereoscopic subtitling content parameters could then use the real-time manipulation features of the workstation to further fine tune the automatically generated stereoscopic subtitling content parameters.

Title: Methods for beating pulp, methods for treating process waters, and methods for producing pulp and paper
Inventor: GOTO SHISEI
IPC: C02F1/00
Filed: 2006-02-09
Abstract: A method for preparing bulky pulp at freeness levels comparable to that obtained by mechanical treatments while suppressing fiber damage and internal fibrillation comprises generating cavitation in the pulp suspension. Preferably cavitation is generated by a liquid jet and resulting fine bubbles are introduced to adjust the pulp suspension to a desired freeness by the impact force induced by collapse of the fine bubbles. Process water containing up to 50% by weight based on total solids, of long pulp fiber fractions is treated by the generated cavitation and returned to the process for stripping contaminants deposited on pulp fibers and/or inorganic particles to reduce contaminates and adhesion, and decrease microorganisms.

Title: Method for improving waterflood performance using barrier fractures and inflow control devices
Inventor: SIERRA LEOPOLDO
IPC: E21B43/30
Filed: 2010-08-17
Abstract: The present invention is directed to a method of hydrocarbon production from a hydrocarbon reservoir. The method includes providing a substantially horizontal wellbore having at least one productive interval within a hydrocarbon reservoir and forming at least one non- conductive transverse fracture in the reservoir along the substantially horizontal wellbore. An injection well is also provided. A fluid is injected into the reservoir through the injection well to displace hydrocarbons within the reservoir toward a production portion of the substantially horizontal wellbore. Hydrocarbons are drained from the reservoir into at least one production interval of the substantially horizontal wellbore. Fluid production from the at least one production interval into the substantially horizontal wellbore flows through an inflow control device that can restrict the fluid flow. A non-conductive transverse fracture can form a barrier within the reservoir to divert injected fluids to increase sweep efficiency and reduce the influx of injected fluids into the production interval.

Title: Process for making a laminated sheet
Inventor: ARBESMAN RAY
IPC: B32B7/08
Filed: 2012-06-18
Abstract: A process is provided for making stiff, lightweight laminate materials. At least one sheet of textured lamina having raised pointed structures is forced against a softer plain lamina so as to embed the structures therein. The pointed structures raised from grooves carved into the surface of the sheet material by means of a set of teeth carried on a knife element. The pointed structures may pierce through the softer lamina such that the protruding tips may be bent over or clinched to prevent their easy withdrawal. Two such texturized lamina may be used to sandwich and pierce through the softer lamina and are co-clinched by the other. In this way a light and stiff laminate is created.
