Abstract: A single still input image is converted into a decomposition video that, when played, appears to be a close facsimile of the input image. Each frame of the decomposition video has a subset of the pixels of the input image that is disjoint from the subset of pixels selected for any other frame. A union of the subsets, represented by each decomposition video frame, contains all the pixels of the input image. To preserve sufficient brightness, a decomposition video generally needs to contain a relatively small number of frames. To achieve effective and efficient blocking, of the content of the input image as it appears in each frame of a decomposition video, the present invention focuses upon a spatial filtering strategy and, preferably, a two-tiered strategy. A first tier focuses upon the obscuring of relatively high frequency spatial frequencies, while a second tier focuses upon the obscuring of relatively low frequency spatial frequencies.

Abstract: An externally mounted bracket system for disc brakes, as especially associated with the drive trains of heavy duty vehicles, wherein a generally T-shaped bracket plate may be secured to the housing of either a transmission or a rear axle, and a fluid pressure brake cylinder and associated braking calipers are mounted to the bracket plate, whereby the bracket system is readily installed adjacent a rotor disc, and is easily accessible for adjustment or repair.
