Title: Aerated flooring systems
Inventor: LARIMORE MARK
IPC: E04F15/024
Filed: 1998-12-09
Abstract: The invention relates to an aerated flooring system for use in athletic arenas or gymnasiums. The flooring system includes a top layer that provides a surface for the activities to be conducted on the floor. The system also includes at least one ventilation device. The ventilation device covers an air flow shaft within the flooring system, helping to prevent debris from falling in the air flow shaft, but allowing air to flow through the ventilation device. The ventilation device allows air to ventilate out of the flooring system. A support layer below the top layer provides support to the flooring system. A ventilation layer below the flooring is sized to allow air movement through the layer. The air flow shafts allow air to travel from the ventilation layer to the ventilation device. A base is below the ventilation layer and provides support for the flooring system above. A blowing device is controlled by a computer system that monitors the system using sensors. The blowing device can provide air circulation through the flooring system by creating air flow through the ventilation layer, through the air flow shafts, into the ventilation device, and out the flooring system. The aerated flooring system can also be adapted to existing conventional flooring systems without the need to tear up and remove the old flooring.

IPC: B41J21/00
Filed: 1998-12-21
Abstract: A system for blending graphical objects using planar map representations is described.  A page description representation of an input document's graphical objects is converted, at least in part, into a planar map representation.  A color is assigned to each region in the planar map as a function of the region's associated paths' transparency characteristics.  In one embodiment, if the graphical processing system exhausts its memory during processing, those paths already converted to planar maps are rasterized.  Any subsequent processing of graphical objects is thereafter performed in raster format.  In another embodiment, an output page is divided into tiles where each tile may be rasterized independent of the other tiles.  In yet another embodiment, graphical objects are processed in reverse order compared to their arrangement in the page description language representation.

Inventor: DOBRESKI DAVID V
IPC: A44B19/16
Filed: 1997-08-14
Abstract: A plastic bag comprises first and second opposing panels, a reclosable zipper, and a slider. The first and second opposing panels are fixedly connected to each other along a pair of sides and a bottom bridging the pair of sides. The reclosable zipper extends along a mouth formed opposite the bottom.    The zipper includes a first track with a first profile and a second track with a second profile. The first and second profiles are releasably engageable to each other. The slider is slidably mounted to the zipper for movement between a closed position and an open position. The first and second profiles are engaged to each other while the slider is in the closed position, and the first and second profiles are disengaged from each other in response to movement of the slider from the closed position to the open position. To prevent the slider from going past the ends of the zipper and to provide adequate end strength that resists stresses applied to the profiles during normal use of the bag, end terminations in the form of posts pass through the male and female tracks adjacent to the ends of the zipper. To retain the posts on the zipper, each of the posts includes enlarged heads at its opposing ends.

IPC: H04B10/572
Filed: 1997-10-09
Abstract: L'invention se réfère à un procédé et à un appareil de traitement de signaux optiques, destinés à produire une boucle de rétroaction de bruit employant le bruit existant à l'intérieur d'un système optique pour saturer une chaîne d'amplificateurs situés après l'unité de branchement, en vue de prévenir une suramplification de canaux d'informations dans un signal multiplexé en division de longueur d'onde contenant des canaux vides, lors du passage de ces canaux à travers des amplificateurs situés en aval. Ce procédé et cet appareil emploient un amplificateur à extraction existant, qui émet un bruit d'émission spontanée amplifiée (ASE) comme effet secondaire. Un coupleur permet de connecter le bruit ASE à un filtre. Le bruit ASE filtré est introduit dans un amplificateur de réseau existant au moyen d'un second coupleur. L'amplificateur de réseau accroît le gain en direction du bruit ASE filtré à un niveau suffisant pour saturer la chaîne d'amplificateurs, sans recours à un dispositif externe producteur de bruit.

Title: Inspection of container mouth using infrared energy emitted by the container bottom
Inventor: SHEPHERD WILLIAM T
IPC: G01N21/90
Filed: 1999-06-07
Abstract: Apparatus and method for inspecting a container having an open mouth and a closed bottom spaced from the container mouth, while the container is hot from its manufacture, includes a light sensor disposed with respect to the container to view the container bottom through the container mouth. Infrared light energy emitted from the container bottom that travels through the container mouth is directed onto the light sensor, and the inside diameter of the container mouth is measured as a function of the light energy directed onto the sensor. The light sensor preferably comprises an area array sensor for developing a two-dimensional image of the container mouth, and the infrared light energy is directed onto the sensor by a telecentric lens arrangement. The area array sensor is disposed within a camera that has an entrance pupil and the telecentric lens arrangement has one focus at infinity directed toward the container bottom and a second focus at the entrance pupil of the camera. The area array sensor is coupled to image processing electronics for determining or calculating a circle of greatest diameter that will fit into the two-dimensional image (FIG. 2) of the container mouth, and treating such circle as indicative of the effective inside diameter of the container mouth.

Title: Printing machine architecture
Inventor: LOFTHUS ROBERT M
IPC: G03G15/16
Filed: 1999-10-13
Abstract: A single pass, multi-color electrophotographic printing machine architecture uses a vertically oriented photoconductive belt. Transfer of the toner powder images occur at the lowermost portion of the photoconductive belt. The photoconductive belt is elliptically shaped, having a major and a minor axis. N image recording stations are positioned adjacent an exterior surface of the photoconductive belt on one side of the major axis thereof. N-1 image recording stations are positioned adjacent the exterior surface of the photoconductive belt on the other side of the major axis thereof. The image recording stations record electrostatic latent images on the photoconductive belt. This architecture optimizes image registration while minimizing the overall height of the printing machine.
