Patent CA-2317132-A1 (CA)
Inventor: BERTONI JONATHAN L
IPC: G06F9/54
Filed: 1998-12-03
Abstract: A scalable single system image ("S3I") operating system architecture for a multi-processing computer system having separate service (16) and computational (18) processors and wherein a unique distinction exists between the processors but both have shared, common access to all of the computer system memory. The computational processors have no input/output ("I/O") devices mapped directly onto them while the service processors have full I/O capability. A single operating system software image presents a single system application programming interface to application programs across all of the processors and a communication mechanism between the computational and service processors allows multiple requests to the service processors and fast, asynchronous interrupt responses to each request. A computational scheduler executes on each computational processor and provides the interface to the service processors where the operating system software executes.

Inventor: YENNER DANIEL LLOYD
IPC: F01N1/06
Filed: 2000-09-14
Abstract: A device for reducing sound emitted by the air intake of a internal combustion engine is provided. The device includes a dampening chamber formed of a one piece construction by rotational molding. Included as part of this mold are two tubular pipe-like sections designating both an inlet and an outlet whereby air is directed into the engine through the inlet and sound emitted by the engine is dampened as it enters the outlet of the silencer. The inlet and outlet are each formed within a pocket constructed in the mold that assists in creating the flow path for air as it moves throughout the chamber. The arrangement of the inlet and outlet in relation to one another assists in defining the sound reduction capability of the instant design and construction.

Patent CA-2329097-A1 (CA)
Inventor: CHAUVIN JEAN GUY
IPC: H04Q11/00
Filed: 2000-12-20
Abstract: The invention allows the checking of the internal performance of a cross-connect for optical networks with respect to both signal performance and proper connections. In a network comprising a number of interconnected cross-connect devices a spare output line of each cross-connect device is arranged to monitor the input port used by a connection within the cross-connect device. This output is coupled to a Performance Monitor (PM) which determines the bit-rate, type of signal (protocol), and further determines the integrity of the signal. By comparing the results of connection monitoring between a series of cross-connect stages, it is possible to deduce or infer the behaviour of the equipment involved in the connection.

Title: Method for producing contact between two circuit layers separated by an insulating layer
Inventor: MARTIN PHILIPPE
IPC: B23K20/10
Filed: 2000-04-25
Abstract: The invention relates to the methods which make it possible to establish contacts between two conductive layers separated by an insulating layer.It consists in pressing the complex (101) formed by these three layers between a sonotrode (105) excited by ultrasound perpendicular to the plane of the complex and an anvil (106) whose face in contact with the complex has protruding ridges (107). Under the effect of the pressure and the ultrasound, the ridges deform the complex and make the insulating layer flow. When the conductive layers come into contact, after contraction of the insulating layer, they become welded to one another under the effect of the ultrasound.It makes it possible to obtain, at low cost, completely ohmic contacts between these two conductive layers.

Abstract: An end user / station can dynamically control the service levels to/from a second user / station (i.e., locally or remotely controlling service levels). The service levels being provided over packet based networks (which may include Internet Protocol (IP) networks). Dynamic control may be provided for either or both of the service level (e.g., priority of transmission, class or type of service, bandwidth, etc.) and allocation of the costs associated with the service levels provided to users of the embodiments. In some embodiments, users, subscribing to a level of service (e.g., a set bandwidth and/or type of service) can request and obtain a different (e.g., better or worse) level of service (e.g., higher bandwidth access, higher priority of transmissions, etc.) for each call or session between the user and a called station over the packet network. Moreover, the level of service provided for the upstream direction (i.e., transmissions from the user) can be different from the level of service provided for the downstream direction (i.e., transmissions to the user). Further, the settlement procedures for the costs of these services can be allocated to the user, to the station called by the user, or a third station.
