Patent CA-2153514-C (CA)
Inventor: PLATT TERENCE CHRISTOPHER
IPC: B66B13/26
Filed: 1995-07-10
Granted: 2004-09-07
Abstract: In a lift installation in which a multi-beam curtain (primary beam) extends across a lift car door opening, auxiliary transmitters direct secondary beams towards a detection zone in front of landing doors. The multi-beam curtain is intercepted by a passenger entering the lift to prevent premature door closure. However, premature closure is also prevented when a passenger stands in front of the landing doors, thereby causing some of the secondary beam to be reflected onto auxiliary receivers. This provides a low cost solution to the problem of non-detection of an obstruction in the closing path of the landing doors, but not intercepting the primary beam system and also provides an increase in the passenger convenience of the lift, as the doors are held open for a passenger approaching the lift, but not yet interrupting the primary beams.

Abstract: A method is provided for accomplishing unified testing of a digital/RF system (10'), comprised of a digital controller (14), a base band processor (20), an RF transmitter (24) and an RF receiver (34). The digital portion of the digital/RF system (10'), including the digital controller (14) and the base-band processor (20), is tested by a digital test technique such as Boundary-Scan testing. Test patterns for the RF elements are down-loaded from the digital controller (14) to the base-band processor via a Boundary-Scan Test Access Port (TAP). Thereafter, the RF transmitter (24) and the RF receiver (34) are tested by applying the test patterns from the base-band processor to the RF transmitter for transmission thereby. The signal produced by the RF transmitter (24) in response to the applied test pattern is converted to a first digital signal stream for processing by the base-band processor (20) to determine the operability of the transmitter. The signal produced by the RF transmitter (24) is also received by the RF receiver (34) for demodulation thereby. The demodulated signal is then converted to a second signal stream for input to the base-band processor to determine the operability of the receiver.

Abstract: The phenomenon of electroendosmosis which occurs in electrophoretic separations and interferes with the efficiency, accuracy and reproducibility of the separations, is suppressed by the inclusion in the separation medium of a dissolved hydrophilic polymer which has been modified by amine groups covalently bonded thereto, in a controlled proportion relative to the polymer. This modified polymer suppresses electroendosmosis in both free zone electrophoresis and molecular sieve electrophoresis. When this modified polymer is used in a capillary, the reduction which it produces in the electroendosmosis is the same as that achieved by coating the capillary wall with a neutral polymer.

Abstract: A flat trapezoidal container provides a generally frustoconical single cavity for snugly sheathing a flower pot. The container is specifically dimensioned sheath a flower pot so as either (a) to leave therebeneath, a surplus of film in an transition zone which is concealable under the flower pot,or (b) form a hexagonal gusset in the bottom. The container is made from two flat panels of heat-sealable film, each shaped in the general form of a trapezium; or from a single web folded double. The lower portion of the container is ornamentally imprinted along a border extending beneath a generally lateral line above the longitudinal axis of the web; and, with a marker in the upper portion, identifies the contents, or provides instructions for their use or care. When the cavity is distended by being partially filled, the entire container, except for a transition zone, presents a smoothly arcuate surface of the frustum of a cone. The lower exterior portion is continuously printed with ornamental design elements without an interruption in the printing, such as is present as an elongated blank rectangle in prior art bags. The transparent upperportion is free from an elongated portion of the printed image near the edges, as in prior art containers. A method is disclosed for forming the printed container which method requires discarding the material for more than one-half of one container for each container made by thermally sealing the equally, but oppositely angulated sides of the trapeziums, and the shorter of the remaining parallel sides.

Abstract: On mesure l'impédance à l'écoulement d'un fluide dans une conduite d'alimentation en fluide. On utilise deux techniques en fonction du débit sélectionné. Pour des débits élevés, la pompe (18) est commandée de manière à faire varier le débit et la variation de pression est divisée par la variation d'écoulement afin de déterminer directement la résistance. Pour des débits faibles, un processeur (14) commande la pompe (18) afin de pomper des quantités de fluide en fonction d'un code binaire pseudoaléatoire. Le signal de pression résultant détecté au niveau de la conduite (22) est décodé suivant ledit code. Les pressions reçues pendant les périodes codées où il ne se produit pas d'écoulement sont soustraites des pressions reçues pendant les périodes codées où il se produit un écoulement. Tout écart de pression est également éliminé et on utilise une approche par estimation selon la méthode des plus petits carrés avec un modèle prédictif linéaire pour déterminer l'impédance. On utilise les coefficients déterminés grâce au modèle pour calculer la résistance à l'écoulement de fluide dans le système. Un superviseur de qualité contrôle le processus de détermination de la résistance et commande l'affichage (28) de la résistance en fonction de la qualité déterminée. Un affichage de résistance (28) affiche en continu la résistance du système.

Filed: 1998-04-30
Granted: 2003-12-30
Abstract: A multi-class digital network is described.      The network supports a plurality of digital services using dynamically-configured service bands to support various transport modes and qualities of service. A network control element receives traffic and network state information from the nodes. The network control element maintains a network topology and uses the network topology to compute route sets for the nodes. The network control element uses the traffic information to compute network size specifications. The switching nodes use rate controllers to divide the capacity of each link among the connection classes according to rules which ensure consistent service attributes for each band across the network. The rate controllers are adapted to support different transport modes and different packet sizes so that the deconstruction and reconstruction of packets at network edge devices is eliminated. The advantage is a flexible multi-class network which dynamically reconfigures to service traffic loads as service demands fluctuate.
