Abstract: A cover for sealing floor penetrations formed from a unitary, continuous piece of thermoplastic material having a rim portion and a recessed portion. The rim portion forms a flange having an outer edge, and the recessed portion extends downward from the rim portion and defines a cavity. The flange portion extends past the floor penetration to contact and rest on the floor, and adhesive layers may be used to create a seal between the cover and the floor.

Abstract: A method of identifying at least one particular person of interest in a collection of digital images taken over time, includes providing the collection of digital images with each digital image containing one or more persons; storing in a digital database an appearance model having a set of features associated with the particular person of interest and a prior probability of the person of interest appearing in images by a particular photographer; and comparing the appearance model with features extracted from the digital images in the collection of digital images and using the prior probability and the appearance model to determine if the particular person of interest is in one or more digital images in the collection of digital images.

Abstract: The present invention relates to a low spatial frequency calibration arrangement for scanning systems. In the method and system of the present invention, calibration is performed to compensate for non-uniformities introduced when light scattering media is scanned. This calibration results in a non-uniformity mapping at each scanning pixel location.
