    Abstract: A process for printing images by means of an electrographic or electrostatic device using a toner that is cured by multiple applications of energy. The toner has energy-activated reactive components such as radiation-curable sites and reactive functional groups. An image is formed on a substrate by the toner without materially activating the reactive components. The reactive components are subsequently activated by applying a first energy source to adhere the image to the substrate by cross-linking and bonding the image permanently to the substrate, or by transferring the image to a second substrate. A second energy source is applied simultaneously with, or subsequently to, the first energy source, to promote cohesive strength of the image by cross-linking within the toner particles that form the image. The resulting image is permanently bonded to the substrate, yielding substantially enhanced image durability and fastnesses.

    Abstract: The present invention is a wavelength-selective optical transmission system that includes a first waveguide for transmitting a multiplexed optical signal therethrough. The system further includes a second waveguide coupled to the first waveguide wherein a least one of the first and second waveguides have a set of wavelength-selective Bragg gratings disposed near a coupling section between the first and second waveguides to reflect a reflecting optical signal back to the first waveguide and for transmitting a contra-directional optical signal and a co-directional optical signal having respectively a contra-directional selected wavelength and a co-directional selected wavelength corresponding to the Bragg gratings. One of the contra-directional and co-directional wavelengths is chosen as a designated wavelength, and the reflecting optical signal and one of the contra-directional or co-directional optical signals are outside of a predefined range surrounding the designated wavelength.

    Abstract: A non-isolated bridge-buck DC—DC converter has self-driven synchronous rectifiers Q5 Q6 in the buck circuits 28 30. Gate electrodes of the synchronous rectifiers Q5 Q6 are connected to midpoints 24A 24B of the bridge circuit. The voltage at the midpoints provides the necessary voltage waveform for switching the synchronous rectifiers Q5 Q6. In another aspect of the invention, voltage shift circuits 34 are provided between the midpoints and the gates of the synchronous rectifiers. The voltage shift circuits are necessary in some embodiments to make sure that the synchronous rectifiers are turned completely OFF when necessary. The present invention provides a more power efficient and less expensive technique for controlling the synchronous rectifiers compared to conventional external driver circuitry.

    Abstract: A reactive toner that is energy-activated is printed by means of an electrographic device such as a laser printer. The reactive toner is printed onto a substrate. Toner components that cross-link and bond the printed toner permanently onto the substrate, or another substrate through a transfer process, are activated by the application of energy to react after printing. Reaction of the energy-activated components may be inhibited with blocking or protecting agents. The image is permanently bonded onto the substrate when the protection provided by the protecting agents is removed by the application of energy to the printed toner. The toner may comprise energy-activated components, colorants, color enhancing polymeric materials, binder resins, internal and external additives such as waxes and charge control agents. The energy-activated components have multiple functional groups that react with active hydrogen, components that contain active hydrogen, or components that are capable of conversion to active hydrogen containing groups.

    Abstract: A method of printing using an ink or meltable ink layer which comprises dyes, pigments or other colorants. Bonding and/or crosslinking of the colorants is provided by the reaction between compounds selected from each of two chemical groups. The first group comprises compounds with functional groups capable of reacting with active hydrogen. The second group comprises compounds with functional groups containing active hydrogen, or compounds with functional groups containing active hydrogen after a conversion process. Either the first group or the second group is present in the ink, and an image is printed with the ink onto a substrate. The substrate comprises either the first or second group, as appropriate, to set up a later reaction with the ink. The reaction is delayed until the image is subsequently transferred to another substrate or is permanently fixed on the substrate, by the presence of protecting or blocking agents, which are removed by the application of heat or other energy. Upon reaction, the colorant is bonded to the substrate.
