Patent CA-2240707-A1 (CA)
Inventor: JASUNAS NICHOLAS J
IPC: H01R4/12
Filed: 1998-06-15
Abstract: A twist-on connector for electrical wires has a shell of insulating material and a metal coil inserted into an aperture in the shell.  The aperture extending from one end of the shell and has an outer tapered section which is threaded to engage the electrical wires.  A beveled section of the aperture extends inwardly from the outer tapered section to an intermediate tapered section.  The intermediate tapered section is formed by a threadless region which is proximate to the beveled section and a threaded region extending inward from the threadless region.  A closed end section of the aperture adjoins the intermediate tapered section.  The coil is frusto-conical with several turns at the larger end engaging the threadless region of the aperture and the smaller end engaging the closed end section of the aperture.  The middle coil portion is spaced from the shell.  Cooperation of the shell aperture sections and the coil enables the coil to be pressed directly into the aperture without having to rotated either component during insertion which was previously required to avoid thread damage.

Patent CA-2242091-A1 (CA)
Inventor: PETRUNKA ROBERT W
IPC: H04M3/51
Filed: 1997-11-27
Abstract: A network call center reduces terminating facilities for calls from customers (1110) to service agents (1200, 1300), and provides the service agents with great flexibility as to where they may locate to service the calls. The network call center includes a network switch (3010) and an Automatic Call Distribution (ACD) server (3020). The network switch receives calls from the customers, sends information regarding the call to the ACD server, and routes the calls to the service agents via local switches (2220, 2320). The ACD  server receives the information from the network switch, queues the customer calls, tracks service agent availability status, and controls the routing of the calls by the network switch. The ACD server instructs the network switch to route a call to one of the local switches only when one of the connected service agents is available to service the call.

IPC: A01K1/035
Filed: 1998-07-22
Abstract: An apparatus for housebreaking pets comprising an animal entrance installed in a standard door of a home and to which is removably secured an animal cage interior to the home.      The end of the cage opposing the animal entryway is affixed with a hinged panel to provide easy access to within the cage to provide food and water for the pet housed therein. As domestic pets wish to avoid contact with their own excrement, the pets quickly learn to go outdoors to take care of their bodily functions rather than do so in the cage where they are otherwise confined. After only a short time, the animals become housebroken and the cage may be removed from the door.

Abstract: Dans une unité de détection d'informations additionnelles SS, la détection d'une corrélation entre un signal d'imagerie Si superposé à un signal antiduplication à spectre étalé et une suite de codes PN est effectuée à chaque section verticale. Quand la valeur de corrélation entre le signal antiduplication qui est superposé au signal d'imagerie Si et dont le spectre est étalé, et un code PN d'inversion d'étalement ne dépasse pas un seuil prédéterminé, la valeur de corrélation calculée à chaque section verticale est ajoutée. On détecte le signal antiduplication à spectre étalé qui est superposé au signal d'imagerie en modifiant le seuil auquel la corrélation entre ce signal antiduplication à spectre étalé qui est superposé au signal d'imagerie Si et le code PN d'inversion de l'étalement est établie d'après un certain nombre de sections verticales constituant un objet de détection de corrélation. Le signal à spectre étalé peut par conséquent être détecté même quand il est dégradé.

Title: Information network access apparatus and methods for communicating information packets via telephone lines
Inventor: TERRY JOHN BRIAN
IPC: H04M11/06
Filed: 1996-09-11
Abstract: Access to a CSMA/CD (Carrier Sense Multiple Access with Collision Detection) network (10) is provided via a telephone line (12) by providing a master modem (34) at the head end and a slave modem (32) at the subscriber end of the line.  The master modem provides a CSMA/CD interface (36) to the network and controls half duplex communications with the slave modem via the line to avoid collisions of information packets on the line. The information packets are enveloped in frames on the line with error checking information; control information between the modems is contained in the same and/or in separate frames. The modulation method and signal bandwidth can be varied depending on errors to provide optimum communications capacity via any particular line, and a ratio of upstream to downstream information packets can be varied depending on buffer fills at the modems. The master modem can be multiplexed for multiple lines. The modulated signal frequencies are above telephone signal frequencies so that each line can be frequency diplexed for simultaneous telephone communications.
