Title: Papermaking fabrics with contaminant resistant nanoparticle coating and method of in situ application
Inventor: CHASE BUD J
IPC: B05D3/12
Filed: 2006-03-06
Abstract: A pape.pi.naking fabric is treated by applying a nanoparticle type coating to improve their resistance to contamination by foreign matter in the papermaking system. The coating is applied during fabric manufacture and cured during heat setting. Alternatively, the coating applied or renewed by utilizing an existing shower or locating a spray boom or other suitable coating application device in the dryer section to apply the coating to the fabric in a controlled, uniform manner. Prior to application of the coating, the fabric is first thoroughly cleaned such as by showering or spraying, and then dried.  Following controlled application of the coating, any excess material is removed by a suitable means, such as by vacuum, and the remaining coating on the fabric is then cured, either by utilizing the ambient heat of the dryer section or by a portable bank of heaters. In this manner, the fabric does not have to be removed from the machine in order to apply or renew the contaminant resistant coating.

Title: Optimized reconfigurable optical add-drop multiplexer architecture with mems-based attenuation or power management
Inventor: DARLING MICHAEL
IPC: H04B10/43
Filed: 2006-03-24
Abstract: A wavelength selective switch architecture (100) for ROADMs for switching the spectral channels of a multi-channel, multi- wavelength optical signal between input and output ports employs a biaxial MEMS port mirror array (106) for optimal coupling efficiency and ITU grid alignment, an anamorphic beam expander (110) for expanding input optical signals to create an elongated beam profile (146), a diffraction grating (112) for spatially separating the spectral channels, an anamorphic focusing lens system (116), an array (118) of biaxial elongated channel MEMS micromirrors, a built-in Optical Channel Monitor, and an electronic feedback control system. The biaxial channel micromirrors are rotatable about one axis to switch spectral channels between ports, and are rotatable about an orthogonal axis to vary the coupling of the spectral channel to an output port and control attenuation of the spectral signal for complete blocking or for a predetermined power level. The architecture affords hitless switching, near notchless operation, ITU channel alignment, high passband, stability over a broad temperature range, and minimum insertion loss through the optimal coupling efficiency enabled by the feedback control system.

At least two but no more than three cards are dealt to a first hand. At least two but no more than three cards are dealt to a second hand. A player wagers on either (i) the first hand having a score closer or equal to a predetermined high value than the second hand, (ii) the second hand having a score closer or equal to the predetermined high value than the first hand, or (iii) the first and second hands having the same score. The predetermined rules make the odds of the first hand having a score closer or equal to the predetermined high value more likely than the second hand having a score closer or equal to the predetermined high value.  Aspects include permitting a player to place an ante bet with a wager on the first hand having a score closer or equal to the predetermined high value than the second hand, collecting the ante bet from the player if the score of the first hand does not equal the score of the second hand, and paying the player an ante bet payoff if the score of the first hand equals the score of the second hand.
