Patent number: 7733311Abstract: A gray scale bistable electro-optic display is driven by storing a look-up table containing data representing the impulses necessary for transitions, storing data representing at least an initial state of each pixel of the display, storing data representing temporal and gray level prior states of each pixel, receiving an input signal representing a desired final state of at least one pixel of the display; and generating an output signal representing the impulse necessary for a transition, as determined from the look-up table, dependent upon the temporal and gray level prior states. Other similar methods for driving such displays are also disclosed.Type: GrantFiled: June 21, 2006Date of Patent: June 8, 2010Assignee: E Ink CorporationInventors: Karl R. Amundson, Robert W.

Patent number: 7705824Abstract: A first apparatus for displaying drawings comprises a housing having an aperture, a drawing sheet comprising electro-optic material movable through the aperture between closed and open positions, and a writing device for writing on the sheet as it moved between its closed and open positions. A second apparatus comprises a display member having a viewing surface, support means for supporting this display member above a floor, an electro-optic medium disposed on the display member, and a movable writing head for writing on the electro-optic medium. Another display comprises an optic medium with two display states visible through a viewing surface. A touch screen is disposed on the opposed side of the optic medium from the viewing surface, and the optic medium is deformable such that pressure applied to the viewing surface will be transmitted to the touch screen.Type: GrantFiled: December 22, 2005Date of Patent: April 27, 2010Assignee: E Ink CorporationInventors: Allan Scott Baucom, Ara N.

Patent number: 7688297Abstract: A bistable electro-optic display has a plurality of pixels, each of which is capable of displaying at least three gray levels. The display is driven by a method comprising: storing a look-up table containing data representing the impulses necessary to convert an initial gray level to a final gray level; storing data representing at least an initial state of each pixel of the display; receiving an input signal representing a desired final state of at least one pixel of the display; and generating an output signal representing the impulse necessary to convert the initial state of said one pixel to the desired final state thereof, as determined from said look-up table. The invention also provides a method for reducing the remnant voltage of an electro-optic display.Type: GrantFiled: February 27, 2006Date of Patent: March 30, 2010Assignee: E Ink CorporationInventors: Robert W.

Patent number: 6662099Abstract: A wireless, in-road traffic sensor system using sensors that are small, low-cost, and rugged. The sensors may be capable of measuring the speed of passing vehicles, identifying the type of passing vehicle and measuring information about roadway conditions, e.g., wet or icy. The sensor includes a wireless transmitter and may be configured for installation beneath a roadway surface. The sensors may be configured as a traffic sensor system including distributed sensors across a roadway system, concentrators for receiving the sensor broadcasts and a central computer for accumulating and organizing the sensed information. The sensed information may also be made available responsive to user requests via the Web through such reports as traffic delays, alternate route planning and travel time estimates. Alternatively, the sensed information may also be used to control traffic through a traffic control means, such as a traffic signal.Type: GrantFiled: May 22, 2001Date of Patent: December 9, 2003Assignee: Massachusetts Institute of TechnologyInventors: Ara N.
