Abstract: A fluid ejection and scanning system includes a fluid ejection assembly. The assembly includes a first plurality of photosensors, and a first plurality of ejection elements. Each of the ejection elements is configured to cause fluid to be ejected when the ejection element is activated. Each one of the photosensors in the first plurality is coupled to a respective one of the ejection elements for activating the ejection element. A second plurality of photosensors captures image data to generate a digital image of a media. A first light source of the system emits a light beam. A control system scans the light beam across the printhead assembly and selectively illuminates the photosensors in the first plurality, thereby activating the ejection elements coupled to the illuminated photosensors.

Abstract: A system and method for adhering a fabric to a backing substrate is disclosed. The system includes at least one roll of a reusable backing substrate, wherein the reusable backing substrate supports the fabric during a printing process. The system also includes at least one roll of fabric and a lamination system for removably adhering the fabric to the backing substrate. A print zone is configured for receiving the backed fabric and prints a pattern on the backed fabric. After the pattern is printed, the fabric is removed from the backing substrate and the backing substrate may be reused in another printing process. The invention is also directed to a method for printing a pattern on a layer of fabric using a reusable backing substrate and a laminated backing substrate used in the disclosed system and method.

Abstract: The present invention provides test trays and test tray systems for assessing the response of a biological sample to a compound or combination of compounds. The compounds or combinations are arranged in a factorial design in wells of the test tray, thereby facilitating the identification of optimal compound combinations and concentrations. The invention also provides methods of fabricating the test trays including the use of programmably controllable fluid dispensing devices. In addition, the invention provides methods of using the test trays and test tray systems to identify a preferred compound or compound combination, e.g., an optimum compound or compound combination.

Abstract: A replaceable printer component includes an array of fluid ejection elements. Each of the fluid ejection elements is configured to cause fluid to be ejected when the fluid ejection element is activated. The component includes optical activation means for activating the fluid ejection elements based on a received light beam.
