Patent number: 8304537Abstract: Heterocyclic compounds incorporating a [1,3]oxazine ring may be used to make chromogenic materials. These molecules switch from a colorless state to a colored form upon addition of either acid or base. In both instances, the [1,3]oxazine ring opens in response to the pH change forming an indolium cation, after the addition of acid, or a phenolate anion, after the addition of base. Alternatively, the switch may occur in response to a change in electrical current or potential or a change in temperature. Chromophores absorb in the visible region of the electromagnetic spectrum. Hence, their formation translates into the appearance of color. These processes are fully reversible and the original colorless state can be regenerated by switching the pH back to neutral. Thus, these halochromic compounds can be used to develop displays, filters, indicators, lenses, sensors, switches, or windows able to switch their color in response to pH changes.Type: GrantFiled: October 17, 2008Date of Patent: November 6, 2012Assignee: The University of MiamiInventors: Massimiliano Tomasulo, Francisco M.

Patent number: 8252209Abstract: We have designed a molecular switch based on the photoinduced opening and thermal closing of a [1,3]oxazine ring. A substituted [1,3]oxazine compound described as having a general (i.e., unsubstituted) structure with fused indoline and benzooxazine fragments such that they share a common bond in the [1,3]oxazine compound: (i) the bond connecting positions 1 and 2 of the indoline fragment and (ii) the bond connecting positions 2 and 3 of the benzooxazine fragment. Irradiation by light of suitable wavelength and intensity of this photochromic compound induces cleavage of a [C—O] bond of the [1,3]oxazine ring to form a phenolate chromophore. The photogenerated (e.g., colored) isomer may revert thermally to the starting (e.g., colorless) oxazine. Alternatively, the switch may be between isomers of the compound that absorb at different wavelengths. Reversible coloration of silica or polymeric materials and switching optical signals may involve many cycles of interconversion between different colored states.Type: GrantFiled: August 6, 2010Date of Patent: August 28, 2012Assignee: The University of MiamiInventors: Francisco M.

Patent number: 8129673Abstract: A method for logging a subsurface formation includes acquiring neutron capture data using a pulsed neutron tool at a plurality of locations along a borehole penetrating the subsurface formation, wherein the plurality of locations include a formation zone that contains water; comparing an apparent water salinity or an apparent water sigma value estimated from the neutron capture data acquired in the formation zone that contains water with a water salinity or water sigma value of a water sample from the subsurface formation to produce a calibration parameter for the neutron capture data; and correcting the neutron capture data, based on the calibration parameter, to produce corrected neutron capture data. The method may further include determining a water saturation from the corrected neutron capture data.Type: GrantFiled: June 26, 2009Date of Patent: March 6, 2012Assignee: Schlumberger Technology CorporationInventors: John F. Vaeth, Charles F. Morris

Patent number: 8048974Abstract: The invention relates to a acrylated-based optical coating composition containing an organic peroxide initiator which presents a low yellowness level. The initiator has a range of free radical energy that is below a predetermined level. The cure process is controlled by the use a catalyst and a low energy initiator to avoid deleterious reactions that can increase yellowness. The composition is well suited to be applied to a lens and cured in the mold to form a coating with reduced yellowness having high adhesion and abrasion-resistant properties. A dye can be introduced into the composition to form a tinted lens.Type: GrantFiled: June 19, 2008Date of Patent: November 1, 2011Assignee: Essilor International (Compagnie Generale d'OptiqueInventor: Ronald Berzon

Patent number: 8044141Abstract: The present invention provides a method for tinting an optical substrate. The method includes the steps of applying a coating composition containing: a polymerisable monomer having a polyoxyalkylene backbone containing at least four contiguous oxyalkylene units, and an abrasion resistant agent and/or a high crosslinking polymerisable monomer to the optical substrate, polymerising the coating composition to form an abrasion resistant coating layer, and introducing a tinting compound into the coating layer to thereby tint the optical substrate. The invention also provides a coating composition and an optical substrate that is tinted according to the method of the invention.Type: GrantFiled: June 17, 2010Date of Patent: October 25, 2011Assignee: Carl Zeiss Vision Australia Holdings LimitedInventor: David Robert Diggins
