Patent number: 8154804Abstract: A lens is presented in which the lens includes a substrate and an electrode layer. The electrode layer is positioned upon the substrate. The electrode layer has radially alternating rings of electrodes and resistive material. When voltage is applied across two adjacent electrodes the profile of the electric field therebetween is linear. When voltage is applied to the rings of electrodes, the optical phase profile of the lens closely approximates the optical phase of ideal spherical aberration correction.Type: GrantFiled: March 25, 2009Date of Patent: April 10, 2012Assignee: e-Vision Smart Optics, Inc.Inventors: Joseph Thomas McGinn, Dwight P. Duston, Anthony Van Heugten

Publication number: 20090120901Abstract: Aspects of the present invention provide patterned electrodes with substantially reduced or removed residue. Aspects of the present invention for removing residue are applicable to any fabricated structure including transparent electrodes. By substantially reducing or removing residue typically associated with methods used to form patterned electrodes, an improvement in performance can be realized by ensuring that the deposition of subsequent materials onto a substrate is not adversely affected by any such residue. In turn, better interconnects can be formed and better coverage of subsequent layers can be achieved. The method for producing patterned electrodes with substantially reduced or removed residue in accordance with the present invention can be used in conjunction with any known method for patterning conductors or electrodes.Type: ApplicationFiled: October 7, 2008Publication date: May 14, 2009Inventors: Lawrence Keith White, Joseph Thomas McGinn

Patent number: 7416902Abstract: An apparatus for airborne particle sorting is provided comprising a charging system adapted for applying an electrostatic charge to the particles, such that particles of at least a first group are deflected to a greater extent than particles of a second group are deflected. A focusing system is adapted for electrostatically focusing substantially at least the particles of the first group into a focused stream that is narrower than the input air stream. A deposition system is adapted for substantially depositing the particles of the first group from the focused stream upon a target surface, where the target surface may be transported to an analysis system capable of analyzing the particles deposited thereon.Type: GrantFiled: September 20, 2004Date of Patent: August 26, 2008Assignee: Sarnoff CorporationInventors: Timothy Allen Pletcher, Peter James Coyle, Joseph Thomas McGinn, David Keller

Publication number: 20040179322Abstract: The invention is directed to a corona charging device having a powder feed with an outlet. The device has an internal charging cavity having an inlet and a charged powder outlet. The powder feed outlet is positioned at the internal charging cavity inlet. The device is adapted to guide a powder stream downstream from the powder feed outlet to the charged powder outlet. The device also includes a corona charger having one or more needle projections (each having a tip) positioned and adapted to facilitate a corona ion flow from the needle projections and intersecting the powder stream. The device also includes a rotating ground electrode adapted to be charged or grounded to attract the corona flow from the needle projections, and to rotate segments of the ground electrode between the internal charging cavity and a ground electrode cleaner.Type: ApplicationFiled: March 11, 2003Publication date: September 16, 2004Applicant: Sarnoff Corporation Delsys PharmaceuticalInventors: Timothy Allen Pletcher, David Keller, Wen Ho, Eugene Samuel Poliniak, John Paul Furda, Joseph Thomas McGinn, Donald Chester Pultorak, Mortaza Kashef

Patent number: 6611241Abstract: Large visual displays are comprised of an array of smaller display devices or modules, each of which displays a portion of the image to be displayed so that together the array of smaller display devices displays the complete image. Unlike conventional large displays which necessarily seek to minimize the edge areas of the smaller display elements that do not display an image so as to minimize the “seams” or gaps between the image portions, the present display device projects image portions scanned from less than the entire display area of the smaller display devices in an array to create an image on a substantially flat panel that is substantially free of visual “seams” or gaps between the image portions. Thus the display device may employ display elements that do not have narrow edges and that are not contiguous to generate overlapping sub-images.Type: GrantFiled: November 25, 1998Date of Patent: August 26, 2003Assignee: Sarnoff CorporationInventors: Arthur Herbert Firester, Donald Barry Carlin, Herschel Clement Burstyn, Dennis John Bechis, Bawa Singh, Joseph Thomas McGinn

Patent number: 6578607Abstract: A diffuser comprises a conduit having a cross-sectional area that increases in a direction fluid flow. In one embodiment, the diffuser is used to reduce the incidence and severity of flow fluctuations that occur in an electrostatic deposition apparatus. In some embodiments, the diffuser includes one or more flow control features. A first flow-control feature comprises one or more appropriately-shaped annular slits through which fluid having a greater momentum than a primary fluid moving through the diffuser is injected into the “boundary layer” near the wall of the diffuser. A second flow control feature comprises one or more annular slits or, alternatively, slots or holes that are disposed at appropriate locations around the circumference of the diffuser through which a portion of fluid flowing in the boundary layer is removed. Boundary-layer flow removal is effected, in one embodiment, by creating a pressure differential across such annular slit or slots.Type: GrantFiled: December 10, 2001Date of Patent: June 17, 2003Assignee: Delsys Pharmaceutical Corp.Inventors: Kerry Dennis O'Mara, David Keller, Joseph Thomas McGinn

Patent number: 6397840Abstract: A dry powder, for example, a medicament for an inhaler, comprises elongated particles with an aspect ratio sufficient to cause the particles to be bound to a preferably metal or non-metallic sheet material substrate at the particle tips by electrostatic deposition and for aligning a plurality of particles with their major axes aligned normal to the, substrate and oriented tip-to-tip. Particles deposited form a low density, high relative void deposition to minimize attractive forces between the particles. This minimizes agglomeration and bonding forces to the substrate facilitating the release of a powdered medicament in an inhaler. Medicament dosages in a substrate pocket are covered by a sealing layer. An embodiment of a drug dosage inhaler substrate and inhaler is disclosed.Type: GrantFiled: June 6, 2000Date of Patent: June 4, 2002Assignee: Delsys Pharmaceutical CorporationInventors: Suggy S.
