Abstract: A fluid ejector head, including a fluid ejector disposed on an ejector support, and a photodetector electrically coupled to the fluid ejector. The fluid ejector head also includes a photon source photonically coupled only to the photodetector. Photons emitted from the photon source interact with the photodetector and generate an activation signal. The activation signal in turn activates the fluid ejector ejecting a fluid away from the fluid ejector.

Abstract: Embodiments of the present invention include hybrid ink delivery systems which allow a flexible arrangement of free ink supplies to be connected to multiple printhead assemblies, while preventing printhead deprime or drooling during setup, and provide control and verification of ink supply replacement through the use of integral memory components on the in supplies.

Abstract: A protective device for attaching to and protecting at least one article includes a cover having an attachment surface and a display surface opposing the attachment surface. An adhesive coating is applied to the attachment surface of the cover to facilitate adhesion of the cover to an article. A removable backing is releasably attached to the adhesive coating and at least one relief notch is formed in the cover through the attachment surface of the cover and terminates beneath the display surface of the cover.

Abstract: An unbacked transport and conditioning printing system for printing a pattern on a fabric is disclosed. The system includes a fabric characterization and tension control subsystem for gathering information on variations in the fabric and an irregularity detection subsystem for detecting irregularities in the fabric, as well as, crease detection and removal. The fabric passes through a fabric drying and conditioning subsystem for characterization of the fabric. The system also includes a fabric control subsystem for advancing the fabric through a print zone, where a pattern is printed on an unbacked fabric. The fabric is transported through a drying and post-processing subsystem and a closed-loop color control subsystem.

Abstract: A filter for a display system is provided which includes a fluid chamber having a selectively moveable filtering fluid, plural electrodes being coupled with the fluid chamber to accommodate establishment of an electric field whereby the filtering fluid may be selectively positioned in an optical path.

Abstract: A method of manufacturing a bioactive fluid dose on an ingestible sheet, comprising the steps of advancing the ingestible sheet to a dispense position, and activating a fluid ejector to dispense essentially a drop of a bioactive fluid onto the ingestible sheet.

Abstract: A mixing apparatus that includes a drop on demand fluid dispenser for adding an additive fluid to a receiver liquid to produce a composite liquid that includes the receiver liquid and the additive fluid.

Abstract: A method of applying an orally-ingestible medicament to an orally-ingestible carrier comprising the steps of controlling a relative position between a fluid ejector and the carrier, and ejecting a plurality of drops of solution onto the carrier, wherein the plurality of drops includes a desired therapeutic quantity of the orally-ingestible medicament.

Abstract: A fluid-ejection assembly of one embodiment is disclosed comprising first and second arrays of fluid-ejection mechanisms, first and second service stations, and first and second drive mechanisms. The first array ejects fluid onto media; the first service station is to service the first array. The second array ejects fluid onto the media; the second service station is to service the second array. The first drive mechanism moves the first array between a first position to eject fluid onto the media and a second position at the first service station, while the second array ejects fluid onto the media in place of the first array. The second drive mechanism moves the second array between a third position to eject fluid onto the media and a fourth position at the second service station while the first array ejects fluid onto the media in place of the second array.

Abstract: Apparatus and methods are provided. Print-mark data corresponding to a print mark on a hardcopy of printed material is extracted from data corresponding to the hardcopy of printed material. The print-mark data is analyzed to quantify printing artifacts of the print mark resulting from printing variations occurring during printing of the hardcopy of printed material. The quantified printing artifacts are encrypted, and the encrypted printing artifacts are encoded into data corresponding to a machine-readable identifier. The machine-readable identifier is printed from the data corresponding to the machine-readable identifier on the hardcopy of printed material.
