Patent CA-2273778-A1 (CA)
Inventor: AINA STEFANO
IPC: H04B10/29
Filed: 1999-06-09
Abstract: Optical telecommunications system, comprising a transmission station generating of transmission signals (1A, 1B) at a minimum of two predetermined wavelengths, a wavelength division multiplexer (3A, 3B) for sending the said transmission signals along an optical fibre line, and at least one power amplifier (5A, 5B), a station for receiving the said transmission signals, comprising at least one preamplifier (7A, 7B) of a device (8A, 8B) for the selective separation of the signals and a receiver (2A, 2B) of the said transmission signals, a plurality of stations (6A, 6B) for amplifying the optical signal, disposed along an optical fibre line which connects the transmission station to the receiving station, and a control unit (18) disposed within each line station.

Patent CA-2278081-A1 (CA)
Inventor: KAWASAKI BRIAN
IPC: G02B6/32
Filed: 1999-07-20
Abstract: The present invention relates to an optical coupling employing an optical element for direct adhesive coupling to an additional optical element. One of the optical elements includes a coupling end face adapted for mating contact with a coupling end face of the second optical element having a continuous groove spaced from an outside edge of the coupling end face defining a peripheral securing surface for receiving adhesive, the groove surrounding a transmission window through which a transmitted signal is coupled into the additional optical element in use. The present invention has found that the planar coupling end faces of the optical elements can be contoured to have an annular groove providing a barrier between a transmission window, where no adhesive disrupts the optical coupling and a peripheral securing surface for providing an adhesive join between the elements. The burner provided by the groove prevents adhesive from migrating and obscuring the transmission window. The direct coupling of planar ferrule and lens surfaces of the present invention provides the advantages of alignment and tuning control. Other optical elements such as multiple lenses, or lenses and filters etc., may also advantageously be coupled in accordance with the invention to provide reliable coupling with an unimpeded transmission area. If the surface contact means used is adhesive, such as epoxy, metal solder, glass solder, molten glass, pressure activated adhesive or the like, between the planar surfaces of the optical elements, surface tension makes it relatively easy to maintain the transmission window free of adhesive for unimpeded transmission. It is also possible to adjust the position of the elements to tune different alignment configurations.

The system includes remote access servers and a remote access server policy manager. Two configurations are practical. In a first configuration, the remote access server is connected to the broadband packet network by an interface that coverts broadband transport protocol to time division multiplexed (TDM) protocol and the remote access server receives the TDM data. In the second configuration, the remote access server includes an integral interface that permits the remote access server to be connected directly to the broadband packet network. In either configuration, data may be passed directly from the remote access server to a gateway to the data network using the broadband packet network. The advantages include, reduction in equipment and trunking infrastructures; flexible allocations of modem terminations across a network; and, economy afforded by an infrastructure shared by a plurality of unrelated service providers.

Patent CA-2299022-A1 (CA)
Inventor: CHAPMAN ALAN STANLEY JOHN
IPC: H04L12/56
Filed: 2000-02-18
Abstract: The present invention relates to a transmission device implementing a flow control mechanism for aggregate trunks. The transmission device can be implemented as a router that includes an input for receiving aggregate traffic streams, an output for releasing the aggregate traffic streams to a destination point and a control unit capable to regulate the rate of release of packets from the output. Specifically, the flow control operation effected by the control unit is dependent on receipt of acknowledgement messages issued at the destination point, each acknowledgement message confirming the receipt of one or more particular packets at the destination point. The control unit will continuously increase the packet sending rate until a packet is lost in the network between the transmission device and the destination point. On detection of packet loss, based on the lack of one or more corresponding acknowledgement messages from the destination point, the control unit will reduce the packet sending rate.

Inventor: CHILMAN JOHN ALFRED
IPC: F16D41/07
Filed: 1998-05-13
Abstract: The invention relates to a directional clutch with a drive element (10-120) and an output element (11;101, 102;130, 131) between which clamping elements (13, 14, 110) are arranged. Said clamping elements are connected to the output element in such a way that they turn without moving in relation to the direction of rotation of the output element both in a free-running position and in a torque transmitting position. The clamping elements are moved in a ring-shaped guide element (12) of the driving element in the free-running position and are blocked in said guide element (12) in the torque transmitting position. According to the invention, the output element consists of radial guides or borings (17;103, 104) each containing a projecting clamping body pin (15,16;111). In the first-mentioned case, the output element can be adjusted in an off-center position relative to the driving element. When adjusted in an offset position the clamping elements cyclically pass through a torque transmitting load path and a load-free path and transfer the occurring torque as they pass from the load-free path to the arched load path through non positive and/or positive engagement with the driving element.
