A process for finishing a wood or wooden board, in particular an MDF or HDF board, with an upper side and an underside. The process includes applying a sealing layer of melamine resin to the upper side of the board and printing a decoration onto the sealing layer. A protective layer is applied of melamine resin to the decoration and the board is pressed under the action of temperature until the protective layer and the sealing layer melt and bond to each other with the inclusion of the decoration printed on.

The invention provides a coating composition for an optical element, such as an ophthalmic lens. The coating composition includes a relatively rigid multifunctional monomer and a relatively flexible difunctional monomer. The rigid multifunctional monomer and the flexible difunctional monomer are capable of co-reacting to form an abrasion resistant coating on the optical element. The invention also provides a method of forming an abrasion resistant coating on an optical element, such as an ophthalmic lens. The method includes the steps of coating the optical element with a relatively rigid multifunctional monomer and a relatively flexible difunctional monomer, and polymerising the coating to form an abrasion resistant coating on the optical element.

Disclosed herein is an image display apparatus, including: a plurality of scanning lines extending along rows and configured to successively supply a control signal in synchronism with a horizontal period in order to perform line-sequential scanning over one field; a plurality of signal lines extending along columns and configured to supply an image signal in accordance with the line-sequential scanning; and a plurality of pixel circuits disposed at locations at which the scanning lines and the signal lines intersect with each other and configured to form a screen.

In one aspect, the present invention is directed to a technique of, and circuitry and system for enhancing the performance of data communication systems using receiver based decision feedback equalization circuitry. In one embodiment, the equalization circuitry and technique employs a plurality of data slicers (for example, two) to receive an analog input and output a binary value based on the reference or slicer level. The output of the data slicers is provided to logic circuitry to determine whether the analog input was a binary high or binary low. In those instances where the data slicers “agree” and both indicate either a high or a low, the logic circuitry outputs the corresponding binary value. In those instances where the data slicer do not “agree”—that is, where one data slicer indicates the input to be a binary or logic high value and the other data slicer indicates the input to be a binary or logic low value, in one embodiment, the logic circuitry outputs the complement of the previous binary value. In another embodiment, the logic circuitry selects the output from the slicer that changed its output from the previous binary value. In yet another embodiment where the slicers do not “agree”, the logic circuitry selects the decision of the data slicer with higher slicer value if the previous binary value was “high”, or selects the decision of the data slicer with the lower slicer value if the previous binary value was “low”. The data slicers employ slicer levels that may be fixed, pre-programmed, predetermined, preset, changed, modified, optimized, enhanced and / or programmed or re-programmed (for example, adaptively) before or during operation of the decision feedback equalization circuitry.

An apparatus for metering, mixing, and spraying liquids is provided. The apparatus includes a first storage chamber and a second storage chamber connected to one another via channels that permit the free flow of air between the first storage chamber and the second storage chamber so that the pressure in each of the chambers is equal. The channels are fitted with liquid flow limiting members for preventing the flow of liquid from the first storage chamber to the second storage chamber and from the second storage chamber to the first storage chamber. Liquid delivery tubes associated with each storage chamber permit liquid from the storage chamber to flow into a mixing chamber. In the mixing chamber, the two liquids combine to form a solution. The concentration of that solution is variably adjustable by means of a flow restriction member associated with the first storage chamber. There is a storage area for receiving the liquids in the storage chambers if the device is tipped onto its side or while moving the device through various angles during its operation.

A tunable dispersion compensator for the compensation of the chromatic dispersion experienced by a single-channel or multi-channel light signal. The compensator includes a plurality of optical structures such as chirped Bragg gratings or combinations thereof, each having a characteristic dispersion profile. An optical coupling arrangement successively propagates the light signal in each of these structures, so that it accumulates the dispersion compensation effect of each. A tuning device jointly tunes the dispersion profile of each optical structure by applying a same tuning force thereto, preferably a temperature gradient.
