Patent CA-2245753-A1 (CA)
Title: Quick release bow-to-cable connector for a covering system
Inventor: BREWER ROBERT RAY
IPC: B60P7/02
Filed: 1998-08-25
Abstract: A connector is provided between a bow end and a cable system that moves the bow across the opening of a container or truck box.  One end of the connector is adapted to mate with the end of the bow.  The other end of the connector has a bore through which the cable passes.  A first open slot in the connector communicates with the bore and is oriented transversely of the bore.  A second open slot extending through a first side of the connector communicates with both the bore and the first open slot and opens in a first direction relative to the connector.  A third open slot extending through a side of the connector opposite the first side communicates with both the bore and the first open slot and opens in a second direction relative to the first direction.  The connector may be conveniently attached to the cable by passing the cable through the first slot into transverse alignment with the bore to the point where it is parallel to the transverse slots.  Subsequent lateral rotation of the connector allows the cable to simultaneously pass through the second and third slots and to become longitudinally aligned within the bore.  Because the subsequent mating of the bow end with the opposite end of the connector restricts lateral rotation in the opposite direction, movement of the connector in a direction other than along the cable is prevented.  This construction permits the connector and associated bow to be readily removed and re-attached to the cable without disassembly of the cable system.

IPC: E21B43/38
Filed: 1998-09-25
Abstract: A downhole oil/water separation apparatus and process which separates solids from total production fluid prior to oil/water separation is disclosed. Production fluid is passed to a downhole solid/liquid cyclone which separates the fluid into a solids enriched stream and an oil/water stream.  The oil is then commingled with the solids enriched stream and brought to surface. The water is reinjected downhole. The method effectively removes solids from the disposal fluid and thus avoids injectivity impairment caused by solids plugging.

Title: Semiconductor device shielded by an array of electrically conducting pins and a method to manufacture such a device
Inventor: NORSTR M HANS
IPC: H01L21/761
Filed: 1997-03-21
Abstract: Low-resistant contacts (205) are made from the surface of a semiconductor component (201), down into the substrate (203) thereof, by means of etching a hole down into the substrate (203), which then, for example, by means of CVD deposition is filled with a metal, e.g. tungsten. Moreover, by further locating such substrate contacts at close distances around a component (201) or a block or a group of components, a very good electrical shielding against other components or blocks of components located on the same substrate is obtained.  Shielding can also be obtained vertically upwards by means of applying a metal layer on top of the component. The metal plugs obtained in this manner can also be used for lateral shielding of electrical signal conductors in a semiconductor structure.

Abstract: Dans un réseau téléphonique cellulaire (10) ARMT ou ARMC incluant plusieurs zones d'enregistrement (32), dans les cas de resélection de cellule de station mobile (16) entre une cellule (12) située dans une zone d'enregistrement et une cellule située dans une deuxième zone d'enregistrement, la station mobile effectue des mesures de puissance des signaux sur le canal de commande ou sur le canal pilote pour établir à la fois la valeur d'hystérésis de resélection classique (30) et une valeur d'hystérésis d'enregistrement additionnel (36). La resélection est effectuée par la station mobile lorsque la puissance des signaux sur le canal de commande ou sur le canal pilote mesurée (26) par rapport à la cellule de la deuxième zone d'enregistrement dépasse la puissance des signaux sur le canal de commande ou le canal pilote mesurée (24) par rapport à la cellule de la première zone d'enregistrement de la valeur totale des valeurs d'hystérésis de resélection et d'hystérésis d'enregistrement. Ceci rend plus difficile d'obtenir la resélection d'une cellule assignée à une zone entre enregistrements, ce qui contribue à atténuer la probabilité d'une consommation inutile de précieuses ressources d'interface cellulaires herziennes et de ressources du système qui résulte du transit d'aller-retour de la station mobile entre deux zones d'enregistrement.

Title: Technique for communicating digitally modulated signals over an amplitude-modulation frequency band
Inventor: CHEN BRIAN
IPC: H04H20/00
Filed: 1999-03-17
Abstract: In a communications system implementing an in-band on channel AM (IBOC-AM) (also known as "hybrid IBOC-AM") scheme, digitally modulated signals are transmitted in a 30 kHz digital band centered at an analog host AM carrier frequency f c. The host AM carrier is assigned to the geographic area served by the communications system for AM radio broadcast. It is likely that a similar IBOC-AM scheme is implemented in an adjacent area which is assigned a second analog host AM carrier having a frequency which is either 20 kHz higher or lower than f c. In that case, the transmission of the digitally modulated signals are interfered by a similar transmission in the adjacent area.      The interference is known as "second adjacent channel interference." To reduce such interference, selected power profiles in accordance with the invention are used to allocate the relative transmission power to the digitally modulated signals in the digital band.

Patent CA-2273519-A1 (CA)
Inventor: HOFMANN ROBERT J
IPC: H04L25/49
Filed: 1999-06-01
Abstract: Line coding mismatches on a transmission channel in a telecommunications network will manifest a constant error signature having a certain number of errored seconds, severely errored seconds, unavailable time and lost sync. errors upon the application of a test pattern comprising a sequence of a first, second and third octet, each repeated a prescribed number of times. The first and second octets remain constant regardless of the nature of the transmission channel, while the nature of the third octet varies according to the transmission rate of the DS0 under test and associated DS1 under test. The test pattern will reveal a line coding mismatch. In a B8ZS environment (64 Kbps clear channel capability), the pattern may be run on any DS0 channel within the DS1. In an AMI-with-ZCS environment (56 Kbps or 64 Kbps restricted), the pattern must run on either channel 1 or 24.
