Inventor: CLARE WILLIAM K
IPC: H04M3/51
Filed: 1995-05-23
Granted: 2007-04-03
Abstract: An agent supervising system is used in a telephone call management and distribution system having a plurality of telephone stations assigned to a plurality of agents. The agent supervising system displays agent activites using distinctive color highlighting and text or icon depictions corresponding to agent identification, location and status information on a map representation and in a directory listing graphically represented on a display at the supervisor's station. The agent supervising system also interacts with an agent locating system for locating agents and displaying the agents on the map representation on the supervisor's display. The prediction of pending abandonment of queued calls and color alarms indicating such pending loss of calls are also provided and the potential financial impact of pending loss of calls are determined and displayed.

Abstract: L'invention concerne un modulateur optique de type Kerr et dispositif de récupération toute optique d'horloge par blocage actif de modes d'un laser à fibre en boucle comprenant un tel modulateur. Le fonctionnement est indépendant de la polarisation des signaux présentés sur l'entrée signal (longueur d'onde de .lambda. s). La longueur d'onde du signal d'horloge fourni par le dispositif est de .lambda. c. Le modulateur est composé d'un nombre pair de tronçons, et dans une réalisation préférée quatre tronçons (T1 , T2 , T3 , T4) de fibre à maintien de polarisation, de longueurs optiques équivalentes, reliés optiquement entre eux par trois épissures (E1,E2,E3) en trois endroits. Aux premier et troisième épissures, les axes neutres de propagation de la fibre à maintien de polarisation sont tournés de 90À. Selon une variante avantageuse de l'invention, à la deuxième épissure, il est inséré dans la boucle un convertisseur de modes, qui comprend un démultiplexeur et un multiplexeur optiques, ainsi que deux chemins optiques à maintien de polarisation les connectant. Le démultiplexeur divise les deux signaux optiques présents dans la boucle du laser à fibre (.lambda. s et .lambda. c) respectivement sur lesdits deux chemins.  Sur le chemin véhiculant le signal d' entrée (.lambda. s) , il est effectué une épissure avec rotation de 90À des axes neutres de maintien de polarisation. Sur l'autre chemin, il n'y a pas de rotation des axes. Ledit multiplexeur recombine ensuite les deux signaux (.lambda. s et .lambda. c).  Application aux télécommunications longue-distances via fibre optique.

Abstract: L'invention porte sur un procédé, ainsi que l'appareil correspondant, permettant de détecter l'emplacement d'une défaillance naissante dans un système électrique isolé. Ce procédé comprend l'application d'une tension d'excitation à une ligne électrique dans le but de produire une impulsion de signalisation de décharge partielle à l'endroit d'une défaillance (34) sur la ligne électrique. On explore la surface de la ligne électrique au moyen de deux détecteurs espacés axialement (30, 32) et adjacents à la surface de celle-ci; ces détecteurs détectant l'impulsion de signalisation de décharge partielle et produisant des impulsions détectées discrètes. On combine ces impulsions détectées pour produire un signal combiné dont le niveau d'amplitude atteint une valeur extrême lorsque la défaillance est située à équidistance des détecteurs. On déplace ceux-ci le long de la ligne électrique jusqu'à ce que la défaillance soit localisée pratiquement à équidistance des détecteurs comme en témoigne le niveau d'amplitude extrême du signal combiné.

Abstract: An adaptive processor (50) which uses the successive range and Doppler outputs of a conventional matched-filter (58)  to improve the signal-to-noise ratio for non white noise/clutter.  The adaptive processor minimizes the output for a given range and Doppler cell with the constraint that the response to signals returning with specified range and Doppler offsets, with respect to the center of the range-Doppler cell,  each have specified values.   Weights are derived (64) which can be applied to range-Doppler outputs in the neighborhood of the range-Doppler cell to minimize its output subject to the constraints.  The weights depend on an estimate of the cross-covariance matrix (60) of the various outputs of the range-Doppler cells that are to be weighted.  The constraint parameters are specified in terms of the ambiguity function of the transmitted waveform. Synthetically  generated  covariance  matrices  (60')  or combinations of measured and synthetic matrices can also be used to produce desired modifications to the resulting range-Doppler response of the adapted process.

Abstract: A handle for rotating an actuator on a railway switch stand about an actuator axis, through an arc of approximately 180° between a first position and a second position. The handle has a connector for connecting it to the actuator, a curved grip and an intermediate portion extending between the connector and the curved grip. A weight is secured to the handle between the connector and the curved grip. The handle has a handle axis generally perpendicular to the actuator axis, the handle axis being generally horizontal when the switch stand is in the first or second position. The curved grip extends from opposite sides of the handle axis in a direction generally radial to the actuator axis. The curved grip has a span with a breadth sufficient to allow grasping above the handle axis when the handle is in the first and second positions while avoiding interference with an underlying surface and allowing relatively easy grasping through an intermediate position approximately mid-way between the first and second positions.

Abstract: Apparatus for measuring gravitational fields comprising a superconducting string (1) fixed at both ends and forming part of a closed superconducting loop inductively coupled to two driving solenoids (L d1, L d2). Displacement of the string in response to a gravitational field is sensed by two magnetic flux transformers each comprising a signal coil and two pick-up coils (L p1, L p2). Pairs of pick-up coils lie in two perpendicular planes providing two independent channels of measurements. The two arms of each flux transformer are balanced to convert only the amplitudes of the string's antisymmetric natural modes into an output voltage. The output voltage of each channel is used to produce a feed-back current distribution (I y1, I y2 ) proximate and parallel to the string. By adjusting the feed-back current, the effectiv e relaxation time and resonant frequency of the first antisymmetric mode of the string ca n be adjusted, while leaving the symmetric modes unchanged, thus increasing the apparatus' sensitivity to gravity gradients.

Abstract: An upper cross member and a lower cross member are formed integrally together to include a cross member having the shape of a box in cross section, and to the front and rear sides thereof are joined floor panels of an automobile.  A trunk room or storage space is formed between right and left side frames to which are joined both ends of the cross member.  A lid for opening and closing an opening located in space between a front seat and a center seat of the automobile is pivotally supported by the cross member that forms a portion of the upper wall of the trunk room.  The lid is normally locked to the floor panel by a locking mechanism having a grip.
