摘要:
The present invention provides a method for making colored silicone hydrogel contact lenses. The method of the invention comprises the steps of: (a) applying a color coat to at least a portion of at least one of molding surfaces of a lens mold with an ink, wherein the ink comprises at least one colorant, a binder polymer, an adhesion promoter, and optionally a diluent, wherein the binder polymer is a copolymerization product of a polymerizable mixture including (i) at least one hydrophilic vinylic monomer; (ii) at least one functionalizing vinylic monomer containing at least one functional group selected from the group consisting of hydroxyl group —OH, amino group —NHR (wherein R is hydrogen or C1 to C8 alkyl), carboxylic group —COOH, epoxy group, amide group —CONHR, and combinations thereof; (iii) at least one silicone-containing vinylic monomer or macromer, and (iv) optionally one or more components selected from the group consisting of a polymerization initiator, a chain transfer agent, and a solvent, wherein the mold has a lens-forming cavity between the molding surfaces, wherein the colored coat contains a first surface exposed to the interior of the lens-forming cavity and a second surface in contact with the molding surface; (b) curing the ink printed on the mold; (c) dispensing a silicone hydrogel lens-forming material into the lens-forming cavity of the mold; (d) curing the lens-forming material within the lens-forming cavity to form the contact lens, whereby the colored coat detaches from the molding surface and becomes integral with the body of the contact lens.

A prepolymer is prepared by reacting a mixture containing (a) at least one multifunctional compound, (b) at least one diisocyanate, and (c) at least one diol. The diol has a weight average molecular weight of at most 6000. The prepolymer, when reacted with an excess of water, forms a hydrogel polymer. The mixture of the prepolymer and water may be reaction molded, and used to form a contact lens.

A method, system and program product for modeling an environment containing a collection of items are disclosed. In accordance with the method, an environmental hierarchy describing a model environment, a product catalog containing data describing a plurality of items that may be utilized to populate the modeled environment, and a configuration library containing data describing a spatial relationship between first and second items among the plurality of items in the product catalog are created. The modeled environment is then populated by storing, in a database, data representative of the spatial relationship between the environmental hierarchy and a collection of items including the first item.

A drywall repair apparatus and method. The apparatus includes a plastic puck that is dimensioned to fill a hole in damaged drywall. The apparatus is anchored inside the wall. The apparatus may have an integrated plastic puck mounted on a plastic plank. The device mounts inside the wall and the puck fills the ½″ deep void, leaving only 1/16″ to be filled with joint compound. There is no time-consuming multiple layering required. There is no need for broad feathering to hide the repair and the repair is as solid as the original wall before damage.

摘要:
A different adaptive control method is used to control a motor during each of two or more phases of motor operation. Thus, in a first phase of motor operation the motor is controlled using a first adaptive control method, in a second phase of motor operation the motor is controlled using a second adaptive control method, and so forth. The motor can be controlled in this manner in any number of phases, in which the motor is used for any of a number of corresponding purposes. The method used in each phase can be optimized to suit that type of operation without compromising operation during other phases.

An inkjet nozzle array includes a plurality of nozzles. Each nozzle includes a chamber having an input aperture adapted to receive ink into the chamber and an output aperture through which ink is ejected from the chamber. Each chamber further includes a window adapted to receive electromagnetic radiation and operable to heat ink in the chamber responsive to the electromagnetic radiation and eject an ink droplet through the output aperture.

A multifunction image processing apparatus is disclosed. The apparatus includes a communications module, a scan subsystem, a print subsystem, and a digital signal processor (DSP) block. The communications module is used to communicate with a host computer to send and receive image data files. The scan subsystem is used to scan images. The print subsystem is used to print images. The DSP block includes at least two digital signal processors. The digital signal processors can be programmed to symmetrically multiprocess portions of an image data file to process it more quickly. Alternatively, digital signal processors can be programmed to simultaneously process the image data for the scan subsystem and image data for the print subsystem.
