Title: Controlling cross machine profile in sheet making
Inventor: TRAN PETER QUANG
IPC: D21G9/00
Filed: 2001-05-14
Granted: 2010-01-26
Abstract: The CD (cross-machine direction) profile of a web of material being produced is monitored and controlled to update CD control settings on-line (i.e. while the processing is operating). Thus, changes in the operation of a machine manufacturing the web can be corrected before significant profile deviations from a desired CD profile target result. Detected variances in the CD profile that satisfy a search criteria initiate searches for improved CD control settings. A CD control performance indicator representative of effectiveness of a CD control is established, and CD mapping settings related to the CD control performance indicator are selected. Improved CD mapping settings are selected online, during sheet manufacture, which produce an improvement in said CD control performance. The CD control recognizes CD actuator mapping misalignments, determines improved CD control settings and applies the improved CD control settings to improve upon or correct mapping misalignments.

Abstract: When a network pages the temporary user mobile identifier of a mobile station, the mobile station sends a response to the network. Next, the network checks the authenticity of the user using a ciphering key, corresponding to the temporary user mobile identifier and a random number. If the temporary user mobile identifier is authenticated, a normal incoming call acceptance procedure is executed. If the mobile station is authenticated although the temporary user mobile identifier is wrong, the network reassigns a new temporary user mobile identifier to the mobile station and stops the current communication. In communication, the network and the mobile station mutually notify encipherment-onset time and negotiate about encipherment manner with each other. In addition, diversity handover is commenced upon a call attempt. Furthermore, if a branch replacement is necessary, the current branch is replaced by new branches capable of executing the diversity handover. Additionally, when a new call occurs to or from the mobile station capable of treating a plurality of calls simultaneously, the mobile station uses the same branch structure and the same communication frequency band for all of calls. Additionally, when a new call occurs to or from the mobile station capable of treating a plurality of calls simultaneously, a branch structure and a communication frequency band, which can continue all of the calls, are selected and used. Therefore, the mobile communications system is suitable for transmission of various sorts of data in accordance with the development of multimedia.

Title: Linear wavelength dwdm
Inventor: THIBAULT SIMON
IPC: H04J14/02
Filed: 2001-10-15
Granted: 2006-10-03
Abstract: The present invention concerns a linear wavelength DWDM that is compact and is adapted for use with fibre ribbons. The device of the present invention includes a first and second port in an optically transmissive medium. The first and second ports are in optical communication with each other through a first and second mirror and a diffraction grating. Preferably, the first mirror is located opposite the first port, and is off-axis with respect to the optical axis. The diffraction grating is located on the same side as the input port, and is in optical communication with the first mirror. The second mirror is located on the same side as the first mirror and is in optical communication with the diffraction grating. The output port is slightly off-axis with respect to the optical axis of the second mirror and is in optical communication therewith. The device of the present invention can be used as a multiplexer, where the second port is used as the input, or as a demultiplexer, where the first port is used as the input. The various parameters of the device are optimised so that the second port permits connection of a fibre ribbon.  The device compensates for the non-linear relationship between equally spectrally spaced wavelengths and physically spaced wavelengths once they have been diffracted.
