Abstract: When cold and in the non-coated state, the aerodynamic profile is substantially identical to a nominal profile determined by the Cartesian coordinates X,Y, Zadim given in Table 1, in which the coordinate Zadim is the quotient D/H where D is the distance of the point under consideration from a first reference plane P0 situated at the base of the nominal profile, and H is the height of said profile measured from the first reference plane to a second reference plane P1. The measurements D and H are taken radially relative to the axis of the turbine, while the X coordinate is measured in the axial direction of the turbine.

Abstract: An energy recovery ventilator (“ERV”) connecting an outside air intake to an outside air supply for an AHU or an interior space. The ERV includes a damper for controlling the outside air inflow to the AHU or the interior space. A humidity sensor and a temperature sensor can be mounted within the inlet air path proximate the damper to monitor the temperature and humidity of outside air approaching the ERV through the outside air intake. The damper can be positioned to according to the measured temperature and humidity of the outside air to control the outside air being supplied to the AHU or the interior space.

Abstract: The present relates to a seal for an energy recovery wheel. The seal comprises a main body defining an inner surface, and a pair of lateral walls extending from each lateral side of the main body. Each lateral wall respectively comprises a free edge defining a lip. The inner surface and lateral walls define a space therebetween. The seal provides for air travelling from one section of the energy recovery wheel to another to turbulate within the space. The inner surface is generally flat and the space may comprise a cavity. The lateral walls may be flexible or rigid. The present also relates to a combination of the seal with the energy recovery wheel.

Abstract: An improved ghost-artifact detection and removal method for high-dynamic range (HDR) image creation and related apparatus are described. A binary ghost map is first generated for each image of the multiple input images by a ghost-artifact detection process, where one of the binary values indicate ghost pixels and the other indicates non-ghost pixels. Each binary ghost map is smoothed to generate a continuous-tone ghost map, by changing the pixel value of each non-ghost pixel of the binary map to a ghost value between the two binary values. The ghost value is calculated using a monotonous function of the distance between the non-ghost pixel of the binary map and the nearest ghost pixel. Ghost pixels in the binary ghost map are kept as fully ghost pixel in the continuous-tone ghost map. This method helps to reduce visibility of artifacts at ghost boundaries without losing small detected ghost regions.

Abstract: In high dynamic range (HDR) image creation, a ghost artifact detection method divides the images (brackets) into multiple tiles, and selects one bracket for each tile as the local reference bracket. The local reference brackets are selected via optimization of an objective function which includes both a component that measures exposure quality of individual tiles and a component that measures correlation between neighboring tiles. The minimization can be realized by constructing a graph for the objective function and calculating a minimum cut of the graph using a graph cut algorithm. Graph examples for three and four image sets are given. Ghost artifact detection is then performed on a tile-by-tile basis by using the local reference bracket for each tile. Ghost maps are generated this way and used for HDR image creation. This method minimizes artifacts due to inconsistencies in local reference bracket selection in areas involved in ghost-inducing objects.

Abstract: A method for detecting ghost artifact in multiple images during high dynamic range (HDR image creation. For each pair of images, multiple individual consistency maps are generated by calculating a consistency function using moving windows of different sizes. The individual consistency maps are combined into a combined consistency map and then binarized. When combining the multiple individual consistency maps, they are first binarized using predetermined threshold values that are window-size-specific. The threshold values are developed beforehand using training images and machine leaning. The final binarized consistency map indicates whether the pair of images are consistent with each other at each pixel location. Then, a ghost-weight map is generated for each image based on the multiple final consistency maps. The ghost-weight map indicates the likelihood of each image pixel being ghost-inducing. The HDR image is generated using the set of images and the corresponding ghost-weight maps.

Abstract: A method for selecting an optimum subset of images from a larger set of images for optimal HDR image creation. For each of the set of images, an exposure quality map is computed by assigning, to each pixel of the image, an exposure quality value based on the pixel brightness value of that pixel. A suitable exposure quality function, typically reflecting the properties of the imaging device, is used for this purpose. Then, for each possible subset of images, the exposure quality maps for the images in the subset are combined using a max operation to generate a combined exposure quality map for the subset. An average pixel value of the combined exposure quality map of the subset is then calculated and serves as a quality score. The subset of images processing the highest quality score are used to generate the HDR image.

Abstract: An apparatus for balancing a tubular cylinder roll having an inner annular face comprises an annular body defining inner and outer faces. These annular body is outwardly biased so as to provide the outer face thereof to sufficiently engage the inner annular face of the tubular cylinder roll so as to stay in position. Weight receiving elements are disposed on the inner face of the annular body for removably receiving balance weights. When the apparatus is mounted to the cylinder roll, the balance weights can be selectively and removably mounted thereto thereby balancing the cylinder roll.

Abstract: Various systems and apparati as well as devices and structures are provided which may be used or incorporated into air handling systems (e.g. (air) ventilation systems and apparati) for the manipulation or control of air in a enclosure such as a building, a room of a structure such as a residence, and the like. Such air handling systems (e.g. ventilation apparati or systems) may for example include an element for the transfer of heat from warm exhaust air (taken from inside an enclosure e.g. a building) to cooler exterior fresh air (drawn into the enclosure e.g. building).

Abstract: The present invention relates to an apparatus for ventilation systems which include an element for the transfer of heat from warm exhaust air (taken from inside a building) to cooler exterior fresh air which is drawn into the building. The present invention in particular provides an apparatus whereby, during a defrost cycle, interior air may circulate through both of the fresh air and exhaust air paths for delivery back into the building, i.e. the warm interior air, used as defrost air, may be able to circulate from the interior of the building into the ventilation apparatus and back to the interior of the building. The apparatus can thus use interior air as defrost air while diminishing or avoiding the creation of a negative air pressure in the building.
