Abstract: IMPROVED SYMBOLOGY DISPLAY METHOD                 FIELD OF THE INVENTION                ABSTRACT OF THE DISCLOSURE     In a digital display system (10) including a stroke scanning mechanism, a method which comprises the  steps  of  displaying  symbology  (100)  and increasing (116) or decreasing (108) the number of symbols  displayed,   including  the  null  symbol depending upon comparisons (104) of actual stroke time to a predetermined stroke time limit.   The symbology is initially displayed by stroke scanning.          The actual stroke time for displaying the symbology is  measured.    The  actual  stroke  time  is  then compared (102) with the predetermined stroke time limit to ascertain whether or not the time limit has been exceeded.   If the stroke time limit is not exceeded (104) and a null symbol is not present in the symbology displayed  (114),  a null symbol  is added  (116).   If the  stroke time limit  is not exceeded (104) and a null symbol is present in the displayed symbology (114), the number of symbols is increased  (116).   If the stroke timing limit is 0xceeded (104) and a null symbol is present (106) in the symbology displayed, the null symbol is removed (110).  If the stroke time limit is exceeded (104) and the null symbol is not present (106), a null symbol  is  added  (112) and  the  number  of  other visible symbols is decreased (108).

Patent CA-2038458-A1 (CA)
Inventor: TOMINAGA SUSUMU
IPC: H04L12/701
Filed: 1991-03-18
Abstract: In a network, a route which can be uniquely identified is constructed by selecting an arbitrary packet-switching node and an arbitrary transmission line in an arbitrary order from the network.   A route memory unit stores data indicating which route is involved in which transmission line within the network.   A congested state detecting unit detects a congested state of a transmission line accommodated within its own node.   The detected congested state is transmitted to another node by a congested state informing unit as congested state information.   A route identifying unit receives the congested state information from the other node and retrieves a route within a corresponding transmission line from the route memory unit to thereby identify the route accommodated within its node.    A route control unit carries out control of the congested state of the identified route on the basis of the received congested state information.   As described above, since traffic passing the transmission line is classified into "route" and grouped, an object whose congestion is to be supervised is limited and each node can regulated only the traffic passing the transmission line in which the congestion occurred in units of routes.

Title: Systemes de localisation de mobiles, a ligne de transmission ouverte
Inventor: HARMAN KEITH
IPC: H01Q13/20
Filed: 1991-02-20
Abstract: Un système de ligne de transmission ouverte permettant de localiser une entité (110) se déplaçant le long d'un chemin prédéterminé emploie des transmissions provenant d'un émetteur éloigné et indépendant (106), en particulier une station de radio ou de télévision payante. Le système comprend deux récepteurs, les deux étant accordés à la fréquence d'émission. L'un des récepteurs (101) reçoit des signaux en provenance directe de l'émetteur (106) par l'antenne (104). L'autre récepteur (102) reçoit le signal en provenance de l'émetteur (106) par une ligne de transmission ouverte (107). Un processeur (103) traite les signaux provenant des deux récepteurs pour détecter la présence de l'entité. Le système peut utiliser des émissions sur différentes fréquences provenant d'une pluralité d'émetteurs espacés les uns par rapport aux autres (402; 403; 404) afin d'assurer la fiabilité et pour minimiser les effets de signaux à chemins multiples. Le système peut employer une ligne de transmission ouverte à vitesse variable (507), comportant un moyen de conducteur central (1100) ayant un élément central perméable (1202) équipé d'un conducteur à enroulement hélicoïdal (1201). L'inductance du conducteur central, et par conséquent la vitesse de propagation de la ligne, est modifiée par un signal à variation périodique (Vm) appliqué au conducteur. L'entité provoque différentes variations de phase pour les vitesses de propagation différentes. Le processeur (103) compare ces variations de phase pour localiser l'entité.

Title: Compact hot melt applicator
Inventor: QUINN GERALD W
IPC: B05C5/04
Filed: 1991-10-23
Abstract: ABSTRACT               An applicator for dispensing hot melt adhesives has a receptacle for storing solid blocks of adhesive, along with a feeding mechanism having a movable arm for advancing a single block of adhesive toward a melting chamber.  A coil spring element is connected to the arm and unwraps as the arm is advanced in order to retain any remaining blocks of adhesive in the receptacle.  At the end of a dispensing operation, the spring exerts just enough force on the arm in a direction away from the melting chamber to relieve pressure against the advanced block, so that the tendency for unwanted molten material to drip from the applicator nozzle is reduced.
