20100242765 | METHODS AND APPARATUS FOR INK DELIVERY TO NANOLITHOGRAPHIC PROBE SYSTEMS - Inkwells adapted for use in direct-write nanolithography and other applications including use of wells, channels, and posts. The wells can possess a geometry which matches the geometry of tips which are dipped into the inkwells. The channels can be open or closed. Hydrophilicity and hydrophobicity can be used to control ink flow. SEM can be used to characterize the inkwells. Ink flow can be monitored with video. Hydrophobic material layers can be used to prevent cross contamination. Microsyringes can be used to fill reservoirs. Satellite reservoirs can be used to prevent bubble formation. | 09-30-2010 |
20100294146 | Stamps with micrometer-and nanometer-scale features and methods of fabrication thereof - Stamps and methods of making stamps for applications in anti-counterfeiting and authentication. The stamps are relatively small in size and feature nanoscale and microscale identification regions and features. High throughput manufacturing and high resolution methods are used to make the stamps including electron beam lithography and optical lithography. Anti-fouling coatings can be applied. | 11-25-2010 |
20100294147 | Apparatus and methods for preparing identification features including pharmaceutical applications - Semi-automated or automated manufacturing of micro- or nanostructured identification features on objects and compositions, and especially pharmaceutical compositions. In particular, a motorized stamping apparatus capable of precise hot embossing with or without closed-loop control of the loading; a modular stamp head for a high-throughput parallel stamping apparatus that comprise an array of compact, error-tolerant, individually temperature-controllable stamping elements; inexpensive stamp holders for said elements, as well as associated methods. The inventive features do not reside in the method of making the stamps. | 11-25-2010 |
20100294844 | Identification features - Methods for providing pharmaceutical compositions and objects with identification regions and identification features which are difficult to detect. Microlithography, nanolithography, and stamping methods are used. The identification features can be positive protrusions or negative indentations with respect to the surface. The identification regions can comprise bar codes and holograms. DPN printing or other lithographies such as electron beam lithography, optical lithography, or nanoimprint lithography can be used to prepare stamps, which are then used to prepare the identification features. Redundant patterns can be formed. The invention is useful for counterfeit prevention. An apparatus for stamping the identification features is also described. | 11-25-2010 |
20100297027 | Overt authentication features for compositions and objects and methods of fabrication and verification thereof - Overt anti-counterfeiting features on objects and compositions, especially pharmaceutical compositions. In a preferred embodiment, a counterfeiting-proof overt feature that presents a visually distinctive optical variable or invariable effect is manufactured on a pharmaceutical composition using a purely physical process. Further preferred are counterfeiting-proof, overt features that comprise at least one engineered array of micro- or nanostructures. Also provided are methods and apparatus for the manufacturing of said overt features on said objects and compositions, including pharmaceutical compositions, and for verifying the authenticity of said features. The inventive features do not reside in the method of making the stamp or the instrument used for stamping. | 11-25-2010 |
20100297190 | IDENTIFICATION FEATURES - Methods for providing pharmaceutical compositions and objects with identification regions and identification features which are difficult to detect. Microlithography, nanolithography, and stamping methods are used. The identification features can be positive protrusions or negative indentations with respect to the surface.

20120100304 | MICROMETRIC DIRECT-WRITE METHODS FOR PATTERNING CONDUCTIVE MATERIAL AND APPLICATIONS TO FLAT PANEL DISPLAY REPAIR - A method for direct-write patterning comprises providing a cantilever having a cantilever end, wherein the cantilever is a tipless cantilever; providing an ink disposed at the cantilever end; providing a substrate surface; and moving the cantilever end or moving the substrate surface so that ink is delivered from the cantilever end to the substrate surface. A method for direct writing of conductive metal or metal precursor comprises providing a tipless cantilever having a cantilever end; providing an ink disposed at the cantilever end, wherein the ink comprises one or more metals, one or more metallic nanoparticles, or one or more metal salts; providing a substrate surface; and contacting the cantilever end and the substrate surface so that ink is delivered from the cantilever end to the substrate surface. | 04-26-2012 |
20120272845 | APPARATUS AND METHODS FOR PREPARING IDENTIFICATION FEATURES INCLUDING PHARMACEUTICAL APPLICATIONS - Semi-automated or automated manufacturing of micro- or nanostructured identification features on objects and compositions, and especially pharmaceutical compositions. In particular, a motorized stamping apparatus capable of precise hot embossing with or without closed-loop control of the loading; a modular stamp head for a high-throughput parallel stamping apparatus that comprise an array of compact, error-tolerant, individually temperature-controllable stamping elements; inexpensive stamp holders for said elements, as well as associated methods.
