Abstract: A method of and apparatus for compensating optical non-linearity in optical devices and transmission systems. Two second order interactions are cascaded  in phase-mismatched second harmonic generation to accumulate a non-linear phase shift of a fundamental wave. The non-linear phase shift can be set to provide a desired amount of non-linearity compensation. Compensation takes place in a compensating medium having a negative effective non-linear refractive index at the design operating conditions of the compensating medium. Compensators incorporating these principles may be incorporated as passive or active components in optical transmitters, repeaters or receivers . Active components may be tuned by varying the operating condition of the compensating medium, for example by controlling temperature or applied stres s. Embodiments of the invention use the compensator as pre- or post-compensator s in an optical amplifier, to eliminate or reduce self-phase modulation in the  optical amplifier that occurs as a result of the Kerr effect.

Title: Manual knife sharpener with angle control
Inventor: FRIEL DANIEL D SR
IPC: B24D15/08
Filed: 2002-01-10
Abstract: A manual knife sharpener is provided with angle control structure. The structure includes a guide member having a guide surface which forms an angle with the abrasive surface of the sharpening member. When the blade is inserted into the space between the abrasive surface and the guide surface the blade presses against the guide surface to displace the guide surface linearly in a direction perpendicular to the guide surface so that the movement is a lateral movement in the same plane without any pivoting or twisting of the guide member. Thus, the angle between the guide surface and the abrasive surface remains constant regardless of the extent of displacement of the guide member.

Patent CA-2401907-A1 (CA)
Inventor: BANNAI VINAY K
IPC: H04L29/12
Filed: 2001-03-02
Abstract: A dual addressing mode is described in which reduced-length addresses (referred to as short addresses) are substituted for standard addresses (referred to as long addresses) for traffic whose source or destination is internal to a given virtual network topology. The required length of short addresses used for a given virtual topology is dependent on the number of devices reachable within the topology. For a virtual topology with less than 256 addressable devices, for example, 8-bit short addresses can be used. When a node within the virtual network sees a packet with a short destination address in the header, the node understands the address to be within the virtual network and routes the packet accordingly. If a source address is a short address, the virtual network can identify the source within the virtual network. For packets originating in the virtual network whose destination is also in the virtual network, both the source and destination addresses can be short addresses. Thus, devices within a virtual network topology are addressable in a dual manner on the data link layer and/or network layer by traffic flowing internal to, or private to, the virtual network. Also described is a technique for automatically assigning source addresses to devices within the virtual network.
