Patent CA-2393648-A1 (CA)
Inventor: SMITH ANTHONY VERNON WALKER
IPC: H04J14/02
Filed: 2002-07-17
Abstract: A connection between a source node and a destination node is automatically routed and switched in a WDM photonic network 1, on receipt of a connection request. A switching and routing mechanism selects a plurality of valid link paths using a path tree, where invalid branches are eliminated based on constraints received with the connection request, and on a link and path cost functions. A regenerator placement tree 25 is used for determining a plurality of viable regenerator paths for each valid link path. On the regenerator placement tree 25, non-viable branches are eliminated based on constraints received with the request and on regenerator availability at the intermediate nodes along the respective path. Next, the switching and routing mechanism assigns a set of wavelengths to each viable regenerator path, and estimates the performance of the path using a Q calculator 39. The regenerator paths are ordered according to their performance and the switching and routing mechanism 30 attempts to setup a path to serve the request.

Title: Method of shifting an image or paper to reduce show through in duplex printing
Inventor: CONROW BRIAN R
IPC: H04N1/12
Filed: 2002-08-20
Abstract: The relationship between first and second side images is evaluated to determine how the position of the paper and/or the size and arrangement of an image can be manipulated to compensate for paper shrinkage caused by fusing. Show through is reduced by performing setup to adjust a pixel clock frequency and/or a photoreceptor speed, determining a residual magnification error, determining margin shifts to compensate for the residual magnification error, and applying the margin shifts. Paper shrink effects on registration can be compensated for using determinations made during a typical printer setup. Show through errors can be reduced without using a paper conditioner to pre-shrink or re-wet the paper. In simplex and duplex printing, the show through errors worsen as the image moves away from the registration edge. Using information obtained during setup, a margin shift is determined that results in a significant reduction in the maximum show through for each image.

Title: Multi-stage lookup for translating between signals of different bit lengths
Inventor: BROWN DAVID A
IPC: H04L12/46
Filed: 2001-03-15
Abstract: A method and apparatus is provided for translating an L-bit input signal to a W-bit output signal such as a virtual network identification signal to an internal virtual network signal. The translation is performed using a multi-stage lookup. The input signal is portioned into a plurality of subsets of bits. A first index to a first stage is provided by combining a portion of bits and a first delta subset of bits. A second index to a second stage is provided by combining data stored at the first index in the first stage and the second delta subset of bits. The corresponding output signal is stored at the last index in the last stage. The use of the multi-stage lookup instead of a single-stage lookup reduces the memory required to perform the translation.

Title: Plasma arc cutting process and apparatus using an oxygen-rich gas shield
Inventor: SOBR JOHN
IPC: H05H1/34
Filed: 1992-03-09
Abstract: A plasma arc torch (10) has a secondary gas flow (46) that is extremely large during piercing of a workpiece (36). The secondary flow (46) exits the torch immediately adjacent the transferred plasma arc (34) and is an extremely uniform, swirling flow. A swirl ring (60) is located in the secondary gas flow path (50) at the exit point. A prechamber (58) feeds gas to the swirl ring (60), which is in turn fed through a flow restricting orifice (56). For certain applications the secondary gas (46) is a mixture of an oxidizing gas and a non-oxidizing gas in a flow ratio of oxydizing to non-oxidizing in the range of 2:3 to 9:1. A network (44) of conduits and solenoid valves (SV1-SV17) operated under the control of a central microprocessor (90) regulates the flows of plasma gas (42) and secondary gas (46) and mixes the secondary gas (46). The network (44) includes valued parallel branches (78,80,84,86) that provide a quick charge capability and a set of venting valves (SV11-SV14), also electrically actuated by the microprocessor (90), to provide a quick discharge. In a preferred high-definition embodiment, a nozzle (28) with a cut back outer surface and a large, conical head (28b) allows a metal seal and enhanced cooling.

Inventor: PHAM BAO
IPC: G06F1/00
Filed: 2001-05-18
Abstract: An interface circuit replaces a selected IDE command received from a host computer with an invalid command and routes the invalid command to a data storage device. In this manner, the interface circuit provides convenient, cost-effective technique for preventing a selected IDE command sent by the host computer from reaching the data storage device. Moreover, by replacing the selected command with an invalid command, rather than merely blocking the selected command, the data storage device can respond with an error message rather than leaving the data storage device and the IDE bus in a non-deterministic state that might require user intervention. The interface circuit is particularly well-suited for preventing a host computer from writing to an IDE hard disk drive in a gaming machine.
