Patent CA-2216434-A1 (CA)
Title: Arcing fault detection system
Inventor: BROOKS STANLEY J
IPC: H02H3/16
Filed: 1997-01-31
Abstract: A system to detect arcing faults in an electrical distribution system with a line conductor connected to a utility power transformer. The system monitors the rate of change of electrical current in the line conductor and produces a signal which represents the rate of change. The system produces a pulse each time the rate-of-change signal exceeds a selected threshold, filters the rate-of-change signal and/or the pulses to substantially eliminate a signal or pulse which represents changes in the electrical current outside a selected frequency range, monitors the remaining pulses to detect when the number of pulses that occur within a selected time interval exceeds a predetermined threshold, and generates an arc-fault-detection signal in response to the occurrence of a number of pulses which exceed the threshold within the selected time interval.

Inventor: MARANDO RICHARD A
IPC: B62D21/11
Filed: 1997-12-10
Abstract: A method of manufacturing a hollow vehicle frame component having at least one relatively sharp bend may include the initial step of pre-forming a generally linear, hollow member into a desired configuration.  The hollow member may be expansion shaped by a hydroforming process.  Next, a section of the hollow pre-formed member is removed at a location where it is desired to provide a relatively sharp bend.  The section is removed along a portion of the pre-formed member so as to divide it into two sections, thereby forming a hinge-like structure therebetween.  The two sections are then bent toward one another such that the edges adjacent the removed section are moved toward one another.  Finally, the adjacent edges are secured together to form the vehicle frame component.  Portions of the edges may abut one another or overlap one another for securement.  A plurality of such bends may be formed in the hollow member.  The ends of the hollow member may extend within a single plane or within different planes.  The magnitude of the angle formed in the member is dependent upon the sized of the section which is removed therefrom.

Title: Method and apparatus for providing speaker authentication by verbal information verification
Inventor: ZHOU QIRU
IPC: G10L15/14
Filed: 1998-05-29
Abstract: A method and apparatus for authenticating a proffered identity of a speaker in which the verbal information content of a speaker's utterance, rather than the vocal characteristics of the speaker, are used to identify or verify the identity of a speaker. Specifically, features of a speech utterance spoken by a speaker are compared with at least one sequence of speaker-independent speech models, where one of these sequences of speech models corresponds to speech reflecting information associated with an individual having said proffered identity. Then, a confidence level that the speech utterance in fact reflects the information associated with the individual having said proffered identity is determined based on said comparison. In accordance with one illustrative embodiment, the proffered identity is an identity claimed by the speaker, and the claimed identity is verified based upon the determined confidence level. In accordance with another illustrative embodiment, each of a plurality of proffered identities is checked in turn to identify the speaker as being a particular one of a corresponding plurality of individuals. The features of the speech utterance may comprise cepstral (i. e., frequency) domain data, and the speaker-independent speech models may comprise Hidden Markov Models of individual phonemes. Since speaker-independent models are employed, the need for each system user to perform an individual training session is eliminated.

Filed: 1998-06-24
Abstract: This invention relates to a mold design, injection molding machine and a method for forming a multi-layer plastic article by over molding where the second layer of the article includes a portion having a different geometrical profile than the first one. The novel injection mold and injection molding machine for producing over-molded articles comprises an array of one or more cores which engage arrays of one or more first cavity and arrays of one or more composite cavities. Each composite cavity is formed from the combination of a second cavity and a cavity extension which carries at least a portion of the different geometrical profile, such as a thread. In one embodiment, the cavity extension comprises a pair of cavity portions which are mounted adjacent the core to laterally moveable slides on a movable plate, that can be a stripper plate. During molding of the first layer, the cavity extension elements are moved "out" of alignment with the first cavity and during molding of the second layer the cavity extension elements are moved "in" to form the composite cavity with the second cavity so that only the second layer replicates the geometrical profile of the composite cavity. In another embodiment of the invention, the cavity extension is a single element which is moved between a disengaged position wherein the core can be inserted into the first cavity and an engaged position wherein the core is inserted into the composite cavity.

Patent CA-2249148-A1 (CA)
Inventor: GRASZER MATTHEW
IPC: B21F45/16
Filed: 1998-10-01
Abstract: A clip and collected assembly thereof are provided and including a method of forming the clip and clip assembly. The clip is formed with at least one slotthat has at least one projection for keeping a resilient cord press fit in the slot therein against forces tending to shift it out therefrom. Preferably, two parallel slots are provided for receiving two cords therein with there being two opposingprojections extending into the slot opening from either side of the slot. The slot projections provide an attendant manufacturing benefit as the punches of the diepress apparatus that punch slugs from the blank fed thereto will not suffer fromslug pulling problems because of the presence of corresponding projections extending into the die cavity openings from either side thereof. In addition, while the clearances between the projection of the die cavity and the punches are at normal tight tolerances, the clearance between the cavity sides and ends and thepunches are oversized so that burrs are formed on the corresponding clip slot sides and ends for gripping the cord and providing additional resistance to shifting in the slot. Improved configurations for the cords are also provided to meet the tolerances required for the press fit in the slots and to be readily severed by an application tool. Special shapes for the slot ends can be provided so that as the cords are press fit therein, areas of weakness will be created in the cords to assist in the severing thereof. Preferred cord materials include those that will not bead when run through spring tempering heat treat ovens, such as nylon and PBT.

Abstract: Afin qu'un panneau décoratif (112) d'une table, du type utilisé dans les bars et les établissements de restauration rapide, puisse être changé facilement suivant la saison, la mode en matière de jeux, etc., l'un des rebords (108) existant autour du bord de la table (100) est conçu pour être détachable du reste de la table, laissant à découvert le bord latéral du panneau décoratif (112). Selon certains modes de réalisation, le panneau (112) est reçu par coulissement dans des rainures (110) formées dans les rebords (108), alors que suivant d'autres modes de réalisation, le panneau est collé à la surface du dessus de la table au moyen d'un adhésif double face (126). Lorsque le panneau est retenu au moyen de rainures, le retrait du rebord détachable (108) permet de faire coulisser le panneau pour le retirer et le remplacer. Par contre, lorsque le panneau est fixé au dessus de la table au moyen d'adhésif double-face (126), le retrait du rebord détachable laisse à découvert un bord du panneau, facilitant l'application de l'action de levier nécessaire pour annuler la force d'adhésion de l'adhésif et désolidariser le panneau de la table, ce qui permet de le remplacer par un autre. Si on le souhaite, des chevilles de verrouillage spéciales (114) à manipuler au moyen d'outils spéciaux, peuvent être utilisées dans la fixation des panneaux pour empêcher tout retrait non autorisé du panneau.
