Granted: 1998-07-07
Abstract: A fault indicator operable from an internal battery for indicating the occurrence of a fault current in a monitored electrical conductor of an AC power distribution system.  Upon occurrence of a fault current a reed switch in magnetic communication with the monitored conductor momentarily closes to connect the internal battery to a capacitor, which is charged by the battery during the switch closure.  The capacitor is connected to the display electrodes of a high impedance liquid crystal display, which displays an "F" to indicate fault occurrence.  The fault indication may be reset either by the slow discharge of the capacitor, by discharging the capacitor through a second reed switch  manually actuated by a magnetic reset tool from outside the fault indicator housing, or automatically upon restoration of power in the conductor.

Title: Fiber optic connection system and method
Inventor: YURTIN JOHN A
IPC: G02B6/40
Filed: 1991-07-04
Granted: 1995-04-18
Abstract: A fiber-optic connection system comprises three interfitting plastic parts.  A two-piece cable terminal includes a cable receiving body and a terminal body.  The terminal body has two spaced projections which mount the fiber ends and has a pair of converging cable guide walls.  The cable receiving body has walls with gripper teeth complementary to the guide walls. When two cable strands are introduced and the bodies are interconnected to form the terminal connector, the walls trap the cables.  The fiber ends are finished by hot plate melting.  The terminal connector is inserted into a header having pockets to mount electro-optical devices.  The pockets have integral spring rails to force the devices into contact with the projections containing the fiber ends upon assembly.  A series of integral lock tangs and shoulders retain the component parts interconnected to prevent inadvertent disassembly.

Title: Simulator using a neural network
Inventor: ONO KAZUTERU
IPC: G05B17/02
Filed: 1992-09-25
Granted: 1996-04-16
Abstract: A simulator includes a modelling simulate section in which properties of an apparatus to be controlled are modelled.  In addition, this simulator includes a neural network in which learning is performed depending on a real control quantity for the apparatus to be controlled.  A correction value relative to a simulation control quantity for the modeling simulate section is calculated in the neural network based on a process quantity output from a controlling unit.  Thereafter, the simulation control quantity is corrected depending on the calculated correction value.  In practice, learning is performed in the neural network by changing a synapse load based on a real quantity for the apparatus to be controlled.   As a result of the foregoing correction, the simulator can simulate the real apparatus more accurately.

Title: Selective radiation of pathological material
Inventor: CYRULNIK REUVEN AVRAHOM
IPC: H01J35/06
Filed: 1991-04-26
Granted: 2002-06-25
Abstract: Radiation of specific material within a subject (30) is accomplished by use of a beam (54) of x-radiation modulated at a microwave frequency. The beam (54) with its modulation is directed at the subject (30) wherein the material interacts with the beam (54) to extract a portion of the radiant energy carried by the beam (54).  In the interaction, an electric field at the modulating frequency appears at the material. By selecting the modulated frequency equal to a resonant interactive microwave frequency of the material, a photon at the microwave frequency is absorbed by the material to alter its physical and chemical properties.

Abstract: L'invention est un système ou une méthode servant à traduire un premier code programme en un second code programme et à exécuter ce second code programme tout en conservant l'atomicité des états des instructions du premier code. Le premier code programme est exécutable sur un ordinateur ayant une première architecture adaptée à un premier ensemble d'instructions et le second code programme est exécutable sur un ordinateur ayant un état de mémorisation et d'enregistrement et une seconde architecture adaptée à un second ensemble d'instructions de taille réduite comparativement au premier ensemble d'instructions. Un premier ordinateur traduit les instructions du premier code en instructions du second code correspondantes selon un code de configuration qui définit les instructions du premier code en fonction de celles du second. Les instructions du second code correspondant à chaque instruction du premier code sont organisées sous la forme d'une suite d'instructions granulaires. Un second ordinateur est adapté à la seconde architecture pour exécuter le second code programme. Durant l'exécution du second code programme, un dispositif dénombre les occurrences de chaque événement asynchrone au cours de cette exécution et les occurrences des conflits d'écriture dans la mémoire occasionnés par un autre processeur, si un tel processeur est connecté à la mémoire. Dans les situations décrites ci-dessus,  l'atomicité et la granularité des instructions du premier code sont au besoin conservées par une interruption complète ou partielle de l'exécution de la suite d'instructions du second code en vue d'une tentative de relance, ou par le retardement du traitement d'une interruption d'événement asynchrone jusqu'à ce que l'exécution de la suite d'instructions du second code soit terminée.

Title: Constrained natural language interface for a computer system
Inventor: LAMBERTI DONNA M
IPC: G06F17/27
Filed: 1993-05-13
Granted: 1998-12-15
Abstract: A  user/computer  interface  is described  that  employ  a constrained  natural language-form  input.   The  computer employs a feedback method to reinforce a user's confidence and knowledge  that  the  computer  comprehends  a  query  or instruction.  The user interface initially parses a user's natural language-form input into a case frame.   The case frame is then filtered into a goal-expression that comprises a verb  and  remaining  syntactical  portions  of  the  input query/instruction.    The   system   then   paraphrases   the goal-expression into constrained natural language-form and communicates the paraphrase to the user for confirmation that the computer system has correctly interpreted the user input.  The computer also compares the goal-expression with prestored goal-expressions to determine a match and then performs an action in response to a match being found.
