Abstract:
Embodiments of the present invention comprise systems, methods and devices for increasing the perceived brightness of an image. In some embodiments this increase compensates for a decrease in display light source illumination.
Abstract:
An insulating end cap for a cylindrical electrolysis cell the type comprising at least two tubular electrodes with a cylindrical membrane arranged co-axially between them, comprises a first annular section with first and second axial ends, having at its first axial end a circular seating or one end of an outer cylindrical electrode and at its second end a circular aperture, of smaller diameter than the circular seating and co-axial therewith, to accommodate one end of the membrane. A second annular section of the end cap is detachably secured to the first and has a central circular aperture of smaller diameter than the central aperture of the first section and co-axial therewith, to accommodate one end of the inner cylindrical electrode. The two part construction of the end cap facilitates the assembly of the cell, and reduces the likelihood of breakage of the fragile ceramic membrane.

Abstract:
A drywall-joint fixture has a drywall-joint cover (1, 33, 37, 42) that can be attached to a drywall arch, wall flat or other drywall structure after a first sheet (3) and a second sheet (4) of drywall of the drywall joint are positioned on wall framework (5, 35, 39) of a building. A paper face (49) that is resistant to sanding is positioned on the drywall-joint cover. The drywall-joint cover includes a first side (6), a second side (7) and an attachment flange (8). The attachment flange is extended orthogonally from an inside surface of either the first side or the second side and is longer than a side opposite from which it is extended for receiving fastener shanks (12) that are stuck through sheets and into a wall framework. A selection of shapes are provided for differing wall structures. A method includes using the attachment flange to maintain the drywall-joint cover in place.

Abstract:
The present application provides a scalable system for managing requests for compute resources using a cloud computing architecture. The system estimates the total processing time of each computation in advance and monitors the progress of each computation to provide a more accurate estimate of remaining processing time. In this way, a determination may be made as each new computation request is received as to whether an additional resource is required or whether an existing resource would be suitable.
Abstract:
The method, system and apparatus embodiments of the present invention provide for rendering original images having high dynamic range into display images having lower dynamic range while retaining a visual quality of rendered images comparable to the original or reference images. Tone-mapping parameters are applied to the display images and are iteratively adjusted in order to reduce the differences between the conditioned original image and the conditioned display image.
Abstract:
An infrared emitter, which utilizes a photonic bandgap (PBG) structure to produce electromagnetic emissions with a narrow band of wavelengths, includes a semiconductor material layer, a dielectric material layer overlaying the semiconductor material layer, and a metallic material layer having an inner side overlaying the dielectric material layer. The semiconductor material layer is capable of being coupled to an energy source for introducing energy to the semiconductor material layer. An array of holes are defined in the device in a periodic manner, wherein each hole extends at least partially through the metallic material layer. The three material layers are adapted to transfer energy from the semiconductor material layer to the outer side of the metallic material layer and emit electromagnetic energy in a narrow band of wavelengths from the outer side of the metallic material layer.
