Abstract: Disclosed herein includes a drug delivery system comprising at least one peptide and a targeting ligand for bone fracture and/or for bone healing. Some embodiments include a peptide delivery system comprising at least an acidic, basic, hydrophilic, hydrophobic or neutral peptide linked to an acidic peptide or nonpeptidic polyanion for use in targeting the aforementioned attached peptide to a bone fracture surface. In some embodiments, a conjugated peptide expresses an anabolic function that acts through PTH receptor 1, and various formats of targeting ligands guide the drug to raw hydroxyapatite.

Abstract: Apparatus to capture aerosols, fluid jetting apparatus, and aerosol diverters are disclosed. An example aerosol capture apparatus includes a corona wire to generate ions, and a reference plate positioned below the corona wire and above a substrate on which a fluid is to be deposited, the reference plate to provide a reference potential to direct the ions toward the reference plate to force aerosol particles associated with the fluid toward the reference plate.

Abstract: A method of dispensing a single ligament of fluid includes ejecting a first quantity of fluid from an inkjet dispenser toward a substrate, and ejecting a second quantity of fluid from the inkjet dispenser toward the substrate, wherein the second quantity of fluid is ejected from the inkjet dispenser at a frequency sufficient that the second quantity of fluid catches the first quantity of fluid thereby forming a single ligament of fluid prior to contacting the substrate.

Abstract: A method for configuring and evaluating documents is described. A printing device accesses data that describes a document which includes one or more user designation areas. The printing device prints a first version of a document with user designation areas. The user completes the user designation areas and the printing device determines which user designation areas have been completed. The printing device accesses data from the computer where printed information is generated based on the completed users designated areas.

Abstract: Solid freeform fabrication systems, powder supply bins for solid freeform fabrication systems, and methods of solid freeform fabrication are disclosed. One exemplary solid freeform fabrication system includes a powder supply bin, a build bin, a roller, and a print head disposed above the build bin that deposits a binder onto the powder in the build bin in a preselected pattern, the supply bin and/or the build bin translating in a x- and/or y-direction relative to the print head.

One exemplary solid freeform fabrication system includes a removable powder supply bin, a build bin, a roller, and a print head disposed above the build bin that deposits a binder onto the powder in the build bin in a preselected pattern.

Abstract: A printer that includes a multi-colorant print cartridge is described. The printer can determine if a level of a most depleted colorant in the multi-colorant cartridge and a level of a least depleted colorant in the multi-colorant cartridge meet predetermined criteria. The printer can, if the criteria are met, perform a default printing procedure to print the document. The printer can, if the criteria are not met, perform an alternative printing procedure to print the document. The alternative printing procedure uses more of the least depleted colorant to print the document as compared to the default printing procedure.
