Granted: 2008-12-02
Abstract: A system for communicating with a card distribution center (40) for selectin g, ordering, and sending social expression cards (120) using a personal computer (5). The user can enter names (130) and addresses (135) of card recipients into the system wherein the inf ormation is maintained in a recipient database (90). The system displays digitized im ages of the cards (figures 8 and 9) on a display screen (10) which are retrieved from a card database (110). From the cards displayed, th e user can select cards for designated recipients and en ter personalized messages (1055) and a digitized signature (1070). The user may then send the order to a card distribution center (40), which processes the order, retrieves and prints the selected card images, includin g any user messages or user signature, and mails the car ds to designated recipients or customers (figure 11). The system maintains a datab ase of all recipients (130), addresses (135), associated occasions and dates (100), card preferences (145), relationships (111, 112) and order history (105).

Title: Separation of touching characters in optical character recognition
Inventor: JAMALI HAMADI
IPC: G06V30/10
Filed: 1996-12-04
Granted: 2000-04-04
Abstract: Method and apparatus for separating touching characters within an optical character recognition (OCR) computer (1). An input document (20) is scanned by scanner (2), forming a set of scan lines (3). A segmentation process (4) is performed on the scan lines (3) to create a set of segmented image boxes (5).      Candidate characters within the image boxes (5) are classified by a classification module (6), based upon a library of stored models (7). When the candidate characters have high degree of confidence, they are classified and coded into a binary form (8), such as ASCII. Those candidate characters that are not classified are processed by a touching character decision module (9) to determine whether a series of separation modules (10-14) is to be invoked. The execution of modules (10-13), followed by the reexecution of modules (4) and (6), may or may not cause all of the touching characters to be separated. Any touching characters that remain are subjected to one or more reprocessing cycles. The reprocessing can entail examination (14) of adjacent scan lines (3), shifting of separation threshold T by separation threshold determination module (10), or re-execution of deconvolution step (12) with changed parameters or structure.

Abstract: A device for measuring metal purity, comprising a receptacle for holding a sample of molten metal, the receptacle being made, at least internally, from an insulating refractory material and having a bottom wall provided with a hole containing a filter element. The bottom wall is substantially impermeable to air except at the hole. An enclosed collection vessel is positioned below the receptacle for collecting molten metal which passes through the filter element from the receptacle, the collection vessel having an opening permitting extraction of gas from within the vessel to enable a vacuum to be generated within the vessel during use of the device. A leak-tight seal is established between-the receptacle for molten metal and the collection vessel to permit vacuum generated in the collection vessel to draw molten metal into the collection vessel from the receptacle through the filter. The receptacle for molten metal has a heat diffusivity value that is sufficiently low that, in use, the temperature of the molten metal in the receptacle does not fall below the liquidus temperature in a period of time required for the vacuum to draw a fixed amount of molten metal sufficient for metal purity testing purposes through the filter and into the collection vessel from the receptacle. The invention also relatesto a corresponding method, and to novel parts of the device.

Abstract: Cette invention concerne un système montable sur des fixations qui sont elles-mêmes montées sur un système de glisse sur neige ou de planche laissant un sillage, lequel système comprend des sangles et s'adapte à la chaussure de l'utilisateur. Lorsque l'on détache une extrémité de chaque sangle de la fixation, lesdites extrémités détachées peuvent être fixées à une barre (11) s'étendant entre les sangles. Un levier de fermeture (10) est monté en un endroit prédéterminé de cette barre d'espacement (12, 14), et offre ainsi un avantage mécanique prédéterminé. Une butée de fermeture (30) possédant une tige rentrante (32) est montée à proximité de l'extrémité avant de la fixation (33), tandis qu'une talonnière de fermeture (20) comportant un verrou (26) est montée à proximité de l'extrémité arrière. Le levier de fermeture entre tout d'abord en contact avec la tige rentrante (32), puis avec le verrou (26), ce qui a pour effet de déplacer la barre d'espacement vers le bas et de serrer les sangles autour de la chaussure. Lors de la première insertion, il peut être nécessaire de régler la tension des sangles; lors des insertions ultérieures, un tel réglage n'est plus nécessaire. Le levier de fermeture (10) peut être libéré du verrou afin de relâcher suffisamment les sangles et de pouvoir ainsi retirer la chaussure. Le verrou peut comporter un système de déclenchement â câble et un blocage de sécurité (28) pour êmpecher le levier de fermeture de se désolidariser du verrou.

Abstract: A fiber array module using soldering, and a fabrication method thereof, are provided. This method includes the steps of forming holes into which optical fibers can be inserted, in a silicon wafer or a ceramic substrate at predetermined intervals, forming a metal layer on the walls of the holes and the entire surface of the substrate, to allow the walls of the holes and the entire surface of the substrate to be plated with a solder alloy material, plating the walls of the holes and the entire surface of the substrate with the solder alloy material, inserting metal-coated optical fibers into the holes plated with the solder alloy material, positioning the optical fibers at the centers of the holes using the surface tension of the solder alloy material, by heating the resultant structure, fixing the optical fibers, inserted into the holes of the substrate, to the substrate by pouring epoxy curable by heat or ultraviolet, to fabricate a fiber array module capable of being accurately attached to an optical waveguide device, and polishing the end of the optical fiber module formed of optical fibers protruding through the holes, to give optical luminance. Accordingly, the environmental characteristics and reliability of a device package are improved upon the connection of the optical fibers. Also, the fiber array module is simply manufactured, and the ends of loaded optical fibers are easily polished, thus fabricating a cheap connection module. Furthermore, the optical fibers are accurately arrayed by the self-alignment using the surface tension of the solder material.
