Publication number: 20130194279Abstract: A system for performing graphics processing is disclosed. A dependency graph comprising interconnected nodes is accessed. Each node has output attributes and the dependency graph receives input attributes. A first list is accessed, which includes a dirty status for each dirty output attribute of the dependency graph. A second list is accessed, which associates one of the input attributes with output attributes that are affected by the one input attribute. A third list is accessed, which associates one of the output attributes with output attributes that affect the one output attribute. An evaluation request for a requested output attribute is received. A set of output attributes are selected for evaluation based on being specified in the first list as dirty and being specified in the third list as associated with the requested output attribute. The set of output attributes are evaluated.Type: ApplicationFiled: September 6, 2012Publication date: August 1, 2013Applicant: DreamWorks Animation LLCInventors: Martin WATT, Alexander P. Powell

Publication number: 20120027520Abstract: A device for damming and diverting liquid on a spill surface has an elongated, pliable dike having a first end, a second end and an exposed surface. The exposed surface is inherently tacky so that it is adherable to the spill surface to prevent flow of liquid past the dike. The dike is preferably made from a substance, such as polyurethane, that is inherently tacky. The device provides improved tear resistance by one or more additions to the construction of the device. Some of the additions to the construction also improve UV resistance and/or chemical compatibility. A method for creating a liquid control zone on a spill surface utilizing the dike of the present invention is also disclosed.Type: ApplicationFiled: January 24, 2011Publication date: February 2, 2012Applicant: NEW PIG CORPORATIONInventors: Beth P.

Patent number: 7937245Abstract: Embodiments are directed to modifying an existing scheme for providing translucent illumination in order to take account of subsurface scattering. The color of a selected point of a translucent object can be determined using existing methods. The existing methods need not take subsurface scattering into account. Then, a contribution to the color at the selected point due to subsurface scattering may be calculated. The contribution due to subsurface scattering may be calculated based on a photon map. Embodiments of the invention also include the use of different types of photon maps. In some embodiments, a standard photon map may be used. In other embodiments, a photon map may be defined in a manner similar to a depth map. Thus, the entries of a photon map may be defined in terms of an angle from a light source and a distance between an object's surface and a light source.Type: GrantFiled: April 2, 2008Date of Patent: May 3, 2011Assignee: Dreamworks Animation LLCInventors: Bruce Nunzio Tartaglia, Alexander P. Powell

Patent number: 7722708Abstract: An indoor air purification apparatus and method includes a watertight chamber including a top portion having a water inlet, a first air portal, a second air portal, a bottom portion, and a plurality of shelves mounted between the top portion and the bottom portion. Water continuously flows from the water inlet at the top of the chamber, typically falling over the shelves to a reservoir. Typically, a water pump returns the water to the water inlet at the top portion of the chamber through at least one conduit leading from the reservoir. An air pump typically drives the room air through the chamber from one air portal to the other and back into the room. The room air is purified as it mixes with the water cascading over the shelves.Type: GrantFiled: December 1, 2005Date of Patent: May 25, 2010Inventors: George P. Powell, Jr., William E. Keeter

Publication number: 20070070130Abstract: The present invention provides systems and methods for providing colorant to a colorant cup apparatus that is adjacent to a pad printing cliché. The fluid colorant is fed from a colorant container through a feed conduit to the cup and an inline viscometer external to the colorant container measures the viscosity of colorant within the feed conduit. A control mechanism can dispense colorant solvent into the colorant container based upon a viscosity measurement performed by the inline viscometer. The disclosed systems, colorant cups and methods are useful in the preparation of tinted contact lenses.Type: ApplicationFiled: September 27, 2005Publication date: March 29, 2007Inventors: Michael Widman, Joseph Ryan, Aiden Flaming, P.

Patent number: 7142659Abstract: A cellular telephone subscriber who wishes directory assistance services is connected in the conventional manner to an operator who identifies a destination telephone number desired by the subscriber. As in the prior art, the operator then initiates a call connecting the subscriber to the destination telephone number. In a preferred embodiment, the operator locates a desired destination telephone number in a computer database, and can select automatic dialing of the located number. Further, rather than dropping all further involvement with the call, the preferred embodiment of the present invention continually monitors the connection thereby established for a predetermined DTMF signal issued by the customer, such as that obtained by pressing the “*” button. If such a signal is detected, the customer is transferred to a directory assistance operator, who can then provide whatever further assistance is needed (e.g. redialing a busy number, or providing further directory assistance).Type: GrantFiled: October 15, 2003Date of Patent: November 28, 2006Assignee: Metro One Telecommunications, Inc.Inventors: Patrick M. Cox, Adrian P. Powell, Paul W. Filliger, Michael A. Kepler
