Patent number: 11821996Abstract: Systems and methods for tracking entities and objects in an environment can include an entity-mounted instrumentation (EMI) and an object-mounted instrumentation (OMI). The OMI can include a first IMU array to detect the object orientation, and a TOF pulse transmitter to transmit a TOF pulse. The EMI can include a second IMU array to detect the entity orientation, a GPS receiver, and an array of TOF sensors to receive various versions of the TOF pulse. The EMI can determine a location and orientation of the entity using GPS data and orientation data generated by the second IMU array. The EMI can determine a relative location of the object using the various versions of the TOF pulse, and can determine a location of the object using the relative location of the object and the location of the entity. The EMI can determine the object orientation using data provided by the first IMU array.Type: GrantFiled: September 28, 2020Date of Patent: November 21, 2023Assignee: LOCKHEED MARTIN CORPORATIONInventors: Peter F.

Publication number: 20230288772Abstract: An electrophoretic display includes an electrophoretic medium having a non-polar fluid and two sets of charged pigment particles dispersed in the non-polar fluid and movable through the non-polar fluid under influence of an electric field. The two sets of charged pigment particles have different optical characteristics from each other. The display also includes a light-transmissive electrode on one side of the electrophoretic medium, a rear electrode on an opposite side of the electrophoretic medium, and a dielectric layer having a dielectric constant greater than 5 between the electrophoretic medium and the light-transmissive electrode or between the electrophoretic medium and the rear electrode configured to reduce electrode electrochemical degradation and buildup of remnant voltages in the display.Type: ApplicationFiled: April 27, 2023Publication date: September 14, 2023Inventors: Cristina VISANI, Stephen J.

Patent number: 11675244Abstract: Layered dielectric materials for use in controlling dielectric strength in microelectronic devices, especially as they relate to electrophoretic and electrowetting applications. Specifically, a combination of a first atomic layer deposition (ALD) step, a sputtering step, and a second ALD step result in a layer that is chemically robust and nearly pinhole free. The dielectric layer may be disposed on the transparent common electrode of an electrophoretic display or covering the pixelated backplane electrodes, or both.Type: GrantFiled: April 30, 2020Date of Patent: June 13, 2023Assignee: E Ink CorporationInventors: Cristina Visani, Stephen J.

Patent number: 10282033Abstract: A method for rendering drawing events on an electro-optic display such that a stylus (pen) stroke is perceived as actually writing on the electro-optic display. Typically, a first line segment is detected and its area is updated using a first drive scheme having faster waveforms. Then a second line segment is detected and its area is updated using the first drive scheme. Thereafter, the areas of both line segments are updated using a second drive scheme different from the first drive scheme, typically involving slower waveforms.Type: GrantFiled: May 17, 2018Date of Patent: May 7, 2019Assignee: E Ink CorporationInventors: Kenneth R.

Patent number: 9996195Abstract: A touch screen electro-optic display is arranged such that upon a touch being detected on the display surface, the display surface surrounding the touch “blinks” by being driven to a different optical state, then back to its original state. A second method uses a display having a pen or stylus which can draw lines upon the display. A first line segment is detected and its area updated using a first drive scheme having short waveforms. The area of a second line segment is updated using the first drive scheme. Thereafter, the areas of both line segments are updated using a second drive scheme different from the first drive scheme.Type: GrantFiled: October 28, 2016Date of Patent: June 12, 2018Assignee: E Ink CorporationInventors: Theodore A.

Patent number: 9620067Abstract: An electro-optic display uses first and second drive schemes differing from each other, for example a slow gray scale drive scheme and a fast monochrome drive scheme. The display is first driven to a pre-determined transition image using the first drive scheme, then driven to a second image, different from the transition image, using the second drive scheme. The display is thereafter driven to the same transition image using the second drive scheme; and from thence to a third image, different from both the transition image and the second image, using the first drive scheme.Type: GrantFiled: November 23, 2015Date of Patent: April 11, 2017Assignee: E Ink CorporationInventors: Demetrious Mark Harrington, Theodore A.
