Patent number: 10459337Abstract: The present invention relates to photoresist compositions comprising a base resin such as a monomer capable of radical polymerization upon photoinitiation, and photoinitiator molecules such as a diketone, and multicolor photolithography methods. Photoresist compositions comprise photoinitiator molecules that are exposed to a first radiation source, thereby exciting the photoinitiator molecules from a ground state to a pre-activated state. The pre-activated state molecules are then exposed to a second radiation source in selected locations, thereby deactivating the pre-activated state molecules in the selected locations. Any remaining pre-activated state molecules are exposed to a third radiation source, exciting such remaining pre-activated state photoinitiator molecules to an activated state. Polymerization of the base resin is then initiated.Type: GrantFiled: December 13, 2016Date of Patent: October 29, 2019Assignee: University of Maryland, College ParkInventors: John T. Fourkas, Daniel E. Falvey, Zuleykhan Tomova, Steven Wolf, Katie Brennan

Patent number: 7452207Abstract: The present invention provides methods and devices for determining an axis of upper and lower jaw articulation of a patient and modeling jaw movement about such an axis, particularly with the use of computerized visual images. The methods comprise providing digital data sets of tooth and bite configuration information which may be used to determine an estimated condylar axis of rotation for a patient. A number of data sets may be acquired and utilized for such estimations. Data sets may be obtained with the use of bite registers. Such registers may be formed by a number of methods and device designs of the present invention. The resulting digital data sets and axis of articulation may then be utilized to generate animated visual images of a patient's jaws in various bite configurations throughout a given rotation around the determined axis.Type: GrantFiled: April 25, 2005Date of Patent: November 18, 2008Assignee: Align Technology, Inc.Inventors: Ross J. Miller, Eric Kuo, Daniel E. Falvey, Andrew H. Trosien

Patent number: 7144700Abstract: Methods, employing a polycyclic hydrocarbon or a polycyclic heteroaromatic compound as sensitizers, are provided to increase the efficiency of removing, by irradiation, photolabile protecting groups that mask reactive sites on synthesis intermediaries. Preferred groups of photolabile protecting moieties include: ((?-methyl-2-nitropiperonyl)-oxy)carbonyl (MeNPOC), ((Phenacyl)-oxy)carbonyl (PAOC), O-(9-phenylxanthen-9-yl) (PIXYL), and ((2-methylene-9,10-anthraquinone)-oxy)carbonyl (MAQOC). In conjunction with using the sensitizers and protecting groups described above, a method of forming, from component molecules, a plurality of compounds on a support, each compound occupying a separate predefined region of the support is provided. These resulting solid-phase arrays are useful, for example, to assay for the presence of biochemical products in biological samples.Type: GrantFiled: July 21, 2000Date of Patent: December 5, 2006Assignee: Affymetrix, Inc.Inventors: Glenn McGall, Daniel E. Falvey, Jacqueline A. Fidanza, Brian M. Feldman
