Publication number: 20070285385Abstract: A system for centrally controlling and messaging electrically active displays distributed at a single site or at multiple sites. A process for creating an electronically addressable display includes multiple printing operations, similar to a multi-color process in conventional screen printing. In some of the process steps, electrically non-active inks are printed onto areas of the receiving substrate, and in other steps, electrically active inks are printed onto different areas of the substrate. The printed display can be used in a variety of applications. This display can be used as an indicator by changing state of the display after a certain time has elapsed, or when a certain pressure, thermal, radiative, moisture, acoustic, inclination, pH, or other threshold is passed. In one embodiment, the display is incorporated into a battery indicator. A sticker display is described. The sticker is adhesive backed and may then be applied to a surface to create a functional information display unit.Type: ApplicationFiled: August 21, 2007Publication date: December 13, 2007Applicant: E INK CORPORATIONInventors: Jonathan Albert, Russell Wilcox, Holly Gates

Publication number: 20060245038Abstract: Disclosed herein are novel electrophoretic displays and materials useful in fabricating such displays. In particular, novel encapsulated displays are disclosed. Particles encapsulated therein are dispersed within a suspending, or electrophoretic, fluid. This fluid may be a mixture of two or more fluids or may be a single fluid. The displays may further comprise particles dispersed in a suspending fluid, wherein the particles contain a liquid. In either case, the suspending fluid may have a density or refractive index substantially matched to that of the particles dispersed therein. Finally, also disclosed herein are electro-osmotic displays. These displays comprise at least one capsule containing either a cellulosic or gel-like internal phase and a liquid phase, or containing two or more immiscible fluids. Application of electric fields to any of the electrophoretic displays described herein affects an optical property of the display.Type: ApplicationFiled: June 27, 2006Publication date: November 2, 2006Applicant: E INK CORPORATIONInventors: Jonathan Albert, Barrett Comiskey, Joseph Jacobson, Libing Zhang, Andrew Loxley, Robert Feeney, Paul Drzaic, Ian Morrison

Publication number: 20050284515Abstract: A flexible solar module is provided sufficient rigidity for use in construction, and comparable rigidity to a glass based solar module, by incorporation of a metal backing to the module, preferably in the laminated module. The rigidity of the construction is enhanced by the inclusion of a corrugation, either in the metal backing, or in a structure that is affixed to the backing. The resulting structure is a modular unit that has connection points and does not need to be connected to other modules to operate. A connection point is provided by an integrated junction box that allows for a simpler installation and the use of standard building techniques for the installation on a roof or wall.Type: ApplicationFiled: June 6, 2005Publication date: December 29, 2005Inventors: Gary Stevens, Milfred Hammerbacher, Glen Crossley, Jonathan Albert

Publication number: 20050122284Abstract: An electro-optic display includes an electro-optic medium, a pixel electrode for applying an electric field to the medium and a column electrode associated with the pixel electrode. To reduce power consumption, when it is necessary to change the voltage on the column electrode from a first value to a second value to change the optical state of the electro-optic medium, the column electrode voltage is first changed to a third value intermediate the first and second values to permit charge to flow to or from the column electrode, and thereafter the column electrode voltage is changed from the third voltage to the second voltage.Type: ApplicationFiled: November 24, 2004Publication date: June 9, 2005Applicant: E INK CORPORATIONInventors: Holly Gates, Robert Zehner, Jonathan Albert

Publication number: 20050122306Abstract: An edge-addressable electronic display is provided including a row electrode in electric communication with a first termination and a column electrode in electric communication with a second termination. The row and column electrodes intersect at a pixel. Both the first and second terminations are disposed proximate to a first edge of the display, and as a result, the pixel may be addressed along the first edge of the display. The display may further include a removable driver circuitry for addressing the pixel in electric communication with at least one of the first and second terminations.Type: ApplicationFiled: October 29, 2004Publication date: June 9, 2005Applicant: E Ink CorporationInventors: Russell Wilcox, Jonathan Albert, Holly Gates

Patent number: 6200508Abstract: Printing techniques are used to build three dimensional structures by depositing successive layers of the device onto a substrate. The layers and/or portions thereof are different materials, e.g., conductors and insulators, which provide the desired functional characteristics of the device. The substrate may be used only to provide a support for the printing process, in which case it will usually be removed after the device is fabricated, or may instead be a functioning part of the fabricated device.Type: GrantFiled: October 27, 1997Date of Patent: March 13, 2001Assignee: Massachusetts Institute of TechnologyInventors: Joseph M.

Patent number: 5961804Abstract: An application-ready electrophoresis material includes a carrier and a dispersion of microcapsules therein, the microcapsules each containing a plurality of phases therein. At least some of the phases contrast visually and and exhibit differential responsiveness to an electric field, such that application of the field determines the visual appearance of the microcapsules. The material exhibits stability such the visual appearance persists despite removal of the field. In one aspect, the invention provides for enhanced stability of the visual appearance. In another aspect, the reflectivity of at least one of the phases is enhanced. In another aspect, one of the phases is particulate in nature and emits visible radiation.Type: GrantFiled: March 18, 1997Date of Patent: October 5, 1999Assignee: Massachusetts Institute of TechnologyInventors: Joseph Jacobson, Barrett Comiskey, Jonathan Albert

Patent number: 5814144Abstract: For paints and the like, an aqueous tinter which does not block dispensing nozzles and which has a viscosity of from 0.05 to 1.5 Ns/m.sup.2 (20.degree. C.) and which contains pigment particles, water, micellising dispersant and a non-micellising auxiliary material. The weight ratio of dispersant to pigment must exceed the ratio which would be present at the Daniel Flow Point for a notional tinter consisting only of the pigment, water and the dispersant. The amount of auxiliary material must be sufficient to enable the tinter to be expelled through a bore 2 mm in diameter and 15 mm long by a pressure of not more than 320 MN/m.sup.2 after storage in the bore at 25.degree. C. for 18 hours under a relative humidity of 50%. Preferred dispersants comprise long chain hydrophilic and long chain hydrophobic moieties which may be poly(alkylene glycol) esters of long chain fatty acids or hydrophobic backbone copolymers with pendant poly(alkylene glycol) moieties as hydrophilic side chains.Type: GrantFiled: August 3, 1995Date of Patent: September 29, 1998Assignee: Imperial Chemical Industries PLCInventors: Jennifer Ruth Coutts, Jonathan Albert Graystone, Trevor Stephen Beverley Sayer
