Abstract: Color management and color-managed workflow concepts are applied to lighting apparatus configured to generate multi-colored light, including lighting apparatus based on LED sources. In particular, color management principles are employed to facilitate the generation of variable color light from a given lighting apparatus based on any of a number of possible input specifications for a desired color. A transformation between an arbitrary input specification for a desired color and a lighting command (182) processed by the lighting apparatus is accomplished via the use of a source color management profile ( 180) for the input specification of the desired color, a target color management profile (172) for the lighting apparatus, and a common working color space. Colors defined in the common working color space may be reproduced or approximated by one or more lighting apparatus.

Title: High efficiency radiant burner with heat exchanger option
Inventor: STEPHENS D REDWOOD
IPC: F23D14/00
Filed: 2006-08-07
Granted: 2016-04-12
Abstract: A radiant burner (10) and optional heat exchanger (90) arrangement where the radiant burner (10) has a generally enclosed cavity (24) defined, at least in part, by fuel gas impermeable surroundings (12,14) and a lower surface (62) of fuel gas permeable burner element (60), wherein cavity (12) preferably has two opening (16a,16b) exposed to an oxidizer source. Sealingly coupled to openings (16a,16b) are mix tubes (50a,50b), each having respective first ends (52a,52b) and second ends (54a,54b), wherein first ends (52a,52b) occupy openings (16a, 16b) and second ends (54a, 54b) extend into and are exposed to cavity (12).  Fuel gas injectors (48a,48b), which during use are in fluid communication with fuel gas (100), are positioned to introduce fuel gas into mix tubes (50a,50b).  Pre-combustion gasses migrate to upper surface (64) and are available for ignition. A thermal fuel flow interrupt may be positioned between fuel gas (100) and gas injectors (48a,48b) to isolate the fuel gas in the event of an overheat malfunction. Because burner (60) functions as a radiant body, increased thermal transfer efficiency over the prior art can be achieved by exploiting this fact, such as by creating a dedicated heat exchanger arrangement (90) for containers (70) placed on or proximate to burner (60).  Exposed surfaces (80,82,84) are established to exploit the relative slow velocity of heated combustion gasses, thereby increasing heat transfer flux into container (70).

Title: Methods and systems for determining reservoir properties of subterranean formations with pre-existing fractures
Inventor: CRAIG DAVID P
IPC: E21B49/00
Filed: 2006-10-02
Granted: 2011-12-13
Abstract: Methods and systems are provided for evaluating subsurface earth oil and gas formations. More particularly, methods and systems are provided for determining reservoir properties such as reservoir transmissibilities and average reservoir pressures of formation layer(s) using quantitative refracture-candidate diagnostic methods. The methods herein may use pressure falloff data from the introduction of an injection fluid at a pressure above the formation fracture pressure to analyze reservoir properties. The model recognizes that a new induced fracture creates additional storage volume in the formation and that a quantitative refracture-candidate diagnostic test in a layer may exhibit variable storage during the pressure falloff, and a change in storage may be observed at hydraulic fracture closure. From the estimated formation properties, the methods may be useful for, among other things, determining whether a pre-existing fracture is damaged and evaluating the effectiveness of a previous fracturing treatment to determine whether a formation requires restimulation.
