Title: Method and apparatus for die jam protection/anticipation and correction
Inventor: LUKAS DANIEL G
IPC: B21C51/00
Filed: 1998-03-04
Abstract: A method and apparatus for protecting a die (1) from damage due to material jams in the material stamping equipment, wherein the material is advanced through the die by press feed rollers (6) powered by a drive motor (5). The position error, of the rollers (6) is monitored by the resolver (11), and the torque, of the drive motor (5) is monitored by a strain gauge (10), during the advance of the material through the die. The monitored position error or torque of the motor (5) is compared to the expected position error or the expected torque. If the monitored position error or torque deviates by more than a tolerance value from the expected position error or torque then the material is moved backwards to a previous position, typically the position at which the material was last stamped. The operation of the material stamping equipment may be stopped after the material is moved back if desired.

Abstract: A water injection plasma arc torch having a nozzle assembly positioned adjacent the discharge end of the electrode of the torch, wherein the torch is capable of operating at a current of 200 amperes or less. The nozzle assembly comprises an inner nozzle mounted adjacent an outer nozzle wherein both inner and outer nozzles have concentric bores for passage of the arc and the plasma gas flow to a workpiece. In addition, the inner nozzle is spaced from the outer nozzle to define a water passage therebetween for directing a flow of water to surround the plasma arc. A gas flow velocity of between about 40 times and about 110 times the water flow velocity provides constriction of the plasma arc, without unduly cooling the plasma arc, and produces good quality straight and bevel cuts in thin section workpieces.

Title: Multi-chip data detector implementation for symmetric differential phase shift keying modulation formats
Inventor: CHAN ANDY
IPC: H04L27/233
Filed: 2000-06-08
Abstract: A multi-chip data decoder implemented for symmetric differential phase shift keying (SDPSK) or symmetric differential quadriphase shift keying (SDQPSK) modulation formats which uses multiple-chip observation intervals to improve performance over conventional symbol-to-symbol differential detection. Input phases .PHI.k, .PHI.k-1 .PHI.k-2,and.PHI.k-3 are detected by comparing a received vector of data bits and parity bits, which contains phase transition information over multiple chips, to the set of ideal vectors of data bits and parity bits, which contain all phase transition possibilities over that set of chips in a noiseless environment.  The multi-chip data detector for decoding incoming modulated data comprises a phase-difference encoder (10, 100) arranged to encode phase-differences .PHI.k-2 - .PHI.k-3 .PHI.k-1 - .PHI.k-2 .PHI.k-.PHI.k-1-.PHI.k-.PHI.k-2 .PHI.k-1-.PHI.k-3 and .PHI.k-.PHI.k-3 of the incoming modulated data during a multiple-chip observation interval to produce a received vector of a predetermined number of data bits and parity bits; a decoder (20, 200) arranged to decode the received vector to produce multiple bit decisions by mapping the received vector with a set of ideal vectors; and a majority voter (30, 300) arranged to choose a bit estimate from the multiple bit decisions by way of a majority rule to produce a final detected symbol from the incoming modulated data during the multiple-chip observation interval. The multi-chip data detection technique performs multiple-chip comparisons in an efficient manner, providing a significant performance and implementation improvement over conventional symbol-to-symbol differential detection while realizing design gate savings of up to 90%.

Title: Establishing connections with a pre-specified quality of service across a communications network
Inventor: GIBSON MARK
IPC: H04L12/56
Filed: 2000-06-29
Abstract: On receipt of a request for a communication session over a communications network, such as an Internet Protocol communications network, a method of establishing a path for this session which provides a guaranteed quality of service is described. In a preferred example the communications network is an MPLS network and the method uses a modified version of the SIP messaging protocol. A number of possible paths for the communication session are identified and ranked according to factors such as traffic levels. Bandwidth along a chosen path is reserved and a messaging protocol such as CR-LDP used to establish this reserved path for the communication session. An advertising mechanism is used to provide entities in the network with information about topology and traffic levels. This enables the ranks to be determined effectively. The communications network has an overlay network of high capacity paths established on it. By arranging for communication sessions to preferably be established using these predetermined high capacity paths the complexity of the topology information required is reduced.

Title: Method and system for creating customized products
Inventor: LEEDS GARY
IPC: G11B27/032
Filed: 2000-07-04
Abstract: A method for creating a customized production using an internet communications system includes providing electronic access through the internet communications system to an archival database. More specifically, the digitized database includes a plethora of individually accessible excerpts which are presorted according to their milieu, such as audio works, visual works and audio/visual works. Additionally, the digitized excerpts are categorized within their respective milieus according to subject matter, and they are further sub-divided within each category according to topic. A customized production can then be created by first choosing a milieu, followed by selection of a category and, then, retrieval of topical excerpts from one or more categories. The retrieved excerpts are then collated, redacted and converted from their digitized format into a predetermined media form (such as a videotape, audiotape, compact disk or DVD). The result is the customized production. Also, one retrieved excerpt can be overlaid with another to create a composite excerpt for use in the customized production.

Particularly, the dispersion shift optical fiber has an incident end to which the signal light is incident and an emission end from which the signal light is emitted, has a dispersion whose absolute value is not larger than 5 ps/nm/km for a light with a wavelength of 1550 nm and a cut-off wavelength longer than the wavelength of the signal light at a fiber length of 2m. The mode elimination device is so constructed as to suppress the optical power of a higher order mode to 1/10 or smaller, more preferably to 1/40 or smaller, of the basic mode optical power in order to satisfy single mode condition in relation to the fiber length.
