| 20100196607 | SYSTEMS AND METHODS FOR FABRICATING DISPLACEMENT SCALES - Methods and systems for forming a displacement scale comprising TIR prisms on a substrate are described. A system for forming the displacement scale includes one or more rollers having a pattern of total internal reflection (TIR) prism features in negative relief. As the rollers are rotated, the scale is formed on the substrate. The rollers may also include pattern features in negative relief. Rotation of the rollers simultaneously forms the displacement scale and the pattern features on the substrate. The TIR prism features of the displacement scale may be oriented to provide measurement of one or more of lateral displacement, longitudinal displacement and angular displacement. | 08-05-2010 |

| 20110050678 | FAST TRANSITIONS OF LARGE AREA CHOLESTERIC DISPLAYS - A gray scale drive scheme for passive matrix displays, more specifically cholesteric liquid crystal displays. Prior to writing an image, the display can be given a black appearance by first driving the pixels to a homeotropic state, then driving the pixels to a focal conic state. The drive scheme then resets pixels by driving the selected pixels to a homeotropic state. Selecting and non-selecting row voltage signals are then used in combination with column voltage signals to write an image to the display. | 03-03-2011 |
| 20110292323 | MULTILAYER DISPLAY CONNECTION - The present disclosure generally relates to multilayer display connections, display devices using the display connections, and tiled displays, in particular tiled reflective cholesteric liquid crystal displays. The displays include substrates that have integral tabs for bringing the electrical connections from one major surface of the display to the opposite major surface of the display. The inactive region of a tiled display is thereby minimized by making the electrical connections to display drivers on the major surface opposite the viewing area. | 12-01-2011 |

| 20100037792 | Apparatus and process for transporting lithographic plates to a press cylinder - Transportation of a lithographic plate uses an indexer to load plates into pods for delivery to a press cylinder via a pod elevator or a pod cart. The plates are imprinted with a bar code, imaged, punched, bent, sheared, corner notched, and registered to a press cylinder. The plates are loaded into the indexer, which moves the loaded plates into a position in alignment with designated pod compartments, and loads the plates into each of the designated pod compartments by indexed movement of an elevator within the indexer. The pod elevator or the pod cart moves the pods proximate to a press cylinder where the plates are unloaded from the pod and loaded onto a press cylinder. A computing device, such as a PLC, directs the process. A vision system senses information from the indexer, pod, pod elevator, and the plate for feedback to a PLC, which initiates all of the foregoing operations. | 02-18-2010 |
