Title: Delayed data transmission system
Inventor: SCHNEIDER HOWARD
IPC: H04M11/00
Filed: 1991-03-25
Abstract: Delayed Data Transmission System Abstract The delayed data transmission system disclosed by the present invention consists of a local electronic transmission system, a physical media for storing facsimile and other data and an inter-city media transportation system. Facsimile users telephone the local electronic transmission system portion of the delayed data transmission system of the present invention in their city. The local electronic transmission system within a given city accumulates on a physical media the facsimile transmissions it is receiving. After accumulating a certain amount  of  transmission  data,  or  perhaps  at  periodical intervals,  the physical media  is transported by physical transportation means to another city. The local electronic transmission system in that city reads the data present on the physical media and transmits the facsimile and other data present on the physical media to the designated destinations via the local telephone system in that city.

Title: Earstem for eyeglasses
Inventor: JANNARD JAMES H
IPC: G02C3/00
Filed: 1990-10-19
Abstract: Earstems (20) for eyewear are configured to define a lateral distance between the earstems which is greater than the width of the head in the anterior temple region so as to prevent any contact of the earstems and the head in that region.  Preferably, the earstems include a diverging section (22), a transition section (24), a converging section (26) and a retaining section (28), wherein the transition section defines the greatest lateral distance between the earstems. The retaining section extends posteriorally from the converging section so as to provide an interfacing surface between the eyewear and the head. The retaining section may be configured so as to accommodate the traction device so as to enhance the retention of the eyewear about the head by increasing the coefficient of static friction between the eyewear and the head.

Title: Optical character recognition system and method
Inventor: HIGGINS RAYMOND L
IPC: G06K9/50
Filed: 1991-08-23
Abstract: A system and method are disclosed for optical scanning and recognition of alphanumeric characters of different sizes and fonts such as E13B, OCRA, OCRB, and Farington 7B type fonts recorded on documents such as bank drafts and checks.  The system comprises an optical scanner, a microprocessor, a read-only-memory (ROM), a random-access-memory (RAM, with a stored program) for storing data and a plurality of predetermined character-identification patterns (templates).  Each template includes three configurations:  an actual pixel pattern (bit configuration) of a character, a configuration representing significant portions of the character which remain the same and do not change despite changes in size of the character, and a configuration representing portions of the character which are given added weight in distinguishing between similar characters.  The scanner optically scans each document and produces a plurality of gray-scale pixel values which are stored in the RAM under control of the microprocessor.  The microprocessor processes the stored pixel values, and effectively locates and segments each character on the document.  The microprocessor then converts the segmented-character pixel values to binary data corresponding to the intervals, and selects, from the plurality of templates, the template that matches the binary data, the matching template serving to identify (recognize) the segmented character.

Abstract: Embouchure de perfursion (10) destinée à une implantation, adaptée pour permettre un accès répété à un tissu spécifique d'un patient, et communiquant avec le tissu par un cathéter interne implanté (52). Les embouchures de perfusions de l'invention comprennent un orifice d'entrée élargi (13) présentant une cavité intérieure en forme d'entonnoir, laquelle va en rétrécissant jusqu'à un passage de diamètre réduit (18). Une valvle de cathéter d'articulation (24) est ménagée à l'intérieur du passage, et elle empêche normalement l'écoulement de fluides par la valve, mais elle laisse passer un filament introduit de l'extérieur (32) tel qu'un cathéter. Après implantation, un filament extérieur (32) introduit dans l'embouchure (10) est guidé par la cavité intérieure de l'embouchure en registre avec la valve du cathéter (24). L'amenée continue du filament (32) provoque le passage du cathéter dans la valve (24). Par la suite, lorsqu'un cathéter (32) est inséré, les agents thérapeutiques perfusés dans le patient ou des liquides organiques peuvent être prélevés. D'autres versions font état de valves de concepts variés (56), et de moyens permettant de changer la direction d'un filament introduit au moyen du présent dispositif de perfusion. D'autres versions d'écrivent également comment laver l'intérieur du dispositif avec un agent antimicrobien (98) afin de prévenir les infections, de même que différentes approches pour relier correctement un cathéter interne (52) à une embouchure de perfusion

IPC: G01F11/24
Filed: 1991-12-04
Abstract: ABSTRACT          A dispensing device, which made be fitted in place of a lid on the mouth of a jar of coffee or other granular material, allows dispensing of the material in measured amounts.  The device has a cylindrical body which houses a rotor with a series of compartments.  The volume of the compartments may be adjusted by the installation of one or more inserts into those compartments.  The rotor is rotated by means of a handle which connects to an axle holding the rotor within the cylindrical body.  After installation of the device on a jar mouth, the jar and device may be inver-ted such that both rest on a planar surface of the device. Almost one-half of the rotor may extend into the jar mouth, allowing a corresponding reduction in the size of that por-tion of the device that sits outside of the jar mouth.
