Abstract: An optical routing switch uses two liquid crystal cells that can produce offsetting rotations of the polarization of the input beam to provide fast, symmetrical switching. The input beam is first polarized and then passes through both liquid crystal cells in series. Both liquid crystal cells have two states (e.g., voltage-off and voltage-on) in which the beam polarization is rotated by predetermined angles (e.g., 0° and 90°), but in opposing rotational directions. A controller selectively rotates the LC cells through a sequence of steps, beginning with a “through” state in which both LC cells are in the first state. The polarization rotations provided by both liquid crystal cells offset one another so the beam polarization remains essentially unchanged. The LC cells can be rapidly switched to a “cross” state in which only one of the LC cells is changed to the second state and the polarization of the beam is rotated by a predetermined degree. The LC cells can then be rapidly switched back to the through state by changing both LC cells to their second state. Once again, the LC cells offset one another so that the beam polarization remains essentially unchanged. While remaining in the through state, both LC cells are allowed to return to the first state to complete the cycle. Both LC cells relax at the same rate and their offsetting polarization rotations cause the beam polarization to remain unchanged throughout the entire relaxation process. A polarization-dependent routing element (e.g., a polarized beamsplitter or birefringent element) routes the beam exiting the LC cells along either of two alternative optical paths based on the beam's polarization.

Abstract: A method of digitally printing reactive ink contained in a heat meltable ink layer comprising dyes or pigments or other colorants, using a thermal printer. The ink layer comprises compounds with functional groups capable of reacting with active hydrogen, and compounds with functional groups containing active hydrogen, or functional groups capable of conversion to active hydrogen containing groups. The reactive ink contains one or more blocking agents which prevent initiation of the reaction during thermal printing. An image is thermally printed onto a substrate, at a first temperature, so that the ink is not reacted during the process of printing on to the medium. The image is subsequently transferred or permanently fixed on the substrate by the application of heat and pressure, which removes the blocking agent and reacts the ink, bonding the colorant to the substrate.

Abstract: An optical equalizer for use primarily with an erbium-doped fiber amplifier has an initial polarizer that convert the input beam to a predetermined polarization, followed by a series of dynamically-adjustable sinusoidal filters that provide attenuation as a sinusoidal function of beam wavelength. Each of the sinusoidal filters has a first liquid crystal cell adjustably rotating the polarization of the beam from the preceding polarizer. This is followed by a second optical element that retards the beam as a sinusoidal function of beam wavelength. For example, the second optical element can be a birefringent crystal that provided a fixed degree of retardance to the beam and a second liquid crystal cell that provides a variable degree of retardance, thereby allowing adjustment of the center frequency of the sinusoidal function. Finally, a third liquid crystal cell adjustably rotates the polarization of the beam. A final polarizer provides amplitude control of the beam based on the polarization rotations introduced by the first and third liquid crystal cells. A controller provides control signals to the liquid crystal cells of each sinusoidal filter so that their combined sinusoidal attenuation functions produce a desired equalization curve.

Abstract: An improved acquisition scheme for a medical imaging and treatment system 100. According to one aspect of the invention, adaptive radiation detection, for determining when therapeutic or diagnostic radiation is being applied, is provided. The imaging device 124 acquires several test images during a preacquisition delay. The maximum intensity level from these test images is defined as the upper limit of a camera 122's response in the darkness. The standard deviation of the intensity distribution is also computed. The image intensity level of the subsequent test images are compared to a radiation detection threshold which is determined to be the upper limit of the camera's dark signal, plus twice the standard deviation of pixel intensity distribution of the dark test images. If the intensities of a statistically significant number of pixels exceeds the threshold, the radiation is considered to be on. According to another aspect of the invention, a single look-up table is used for both the test images and the actual acquisition images. The single look-up table is downloaded upon detection of power to a linear accelerator 101. According to still another aspect of the present invention calibration of a lower bound of a signal of interest occurs using a histogram based algorithm, so that only the histogram needs to be transferred from the imaging board to the host computer. Furthermore, the present invention is capable of automatically calculating the upper bound of a signal of interest. In addition, the present invention is configured for continuous image integration such that each acquisition cycle is repeated until the linear accelerator 101 is turned off. Thus, the final image is the integration of images from each acquisition cycle.

Abstract: An intermediate media having a transferable UV stabilizer receives a printed image. A transferable UV absorber and/or free radical scavenger is present. The image, or dye layer, and UV stabilizer are transferred to a final substrate during subsequent heat transfer and activation. Alternatively, the UV stabilizer may be heat transferred from the intermediate transfer media onto a previously transferred image. The UV stabilizer is resistant to laundering at elevated temperatures after transfer and imparts no hand to the final substrate. The intermediate transfer media may comprise multiple layers including a layer containing one or more UV stabilizers. A release layer may be applied beneath the UV stabilizer layer. The release and UV stabilizer layers may sit beneath a dye screening layer. One layer may be a liquid permeable, gas impermeable membrane.

Abstract: A color image is printed onto a first substrate, which acts as an intermediate medium, using lithography, intaglio, gravure, relief printing or other printing process which uses plates. The image is subsequently transferred from the intermediate medium to a final substrate, which may be a textile of natural fabric, such as cotton.Bonding and/or crosslinking of the color images are 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, such as isocyanate or epoxy groups. The second group comprises compounds with functional groups containing active hydrogen, or compounds with functional groups containing active hydrogen after a conversion process. The functional groups of one or both reactive chemical groups are protected either by chemical blocking with blocking agents or by physical barrier such as encapsulating agents. The blocking agents are removed by the application of heat during the transfer of the image from the first substrate to the final substrate.

Abstract: A liquid ink is produced for practicing a method of printing the liquid ink onto a medium for subsequent thermal transfer to a substrate. Insoluble heat activated dyes, such as sublimation or dye diffusion dyes, are heated to above their melting temperature to the same phase as the solvent, which is usually water. Additives and/or stabilizers are added to form micelle particles upon cooling of the material, without separation of the insoluble components, to produce the liquid ink.
