Capture plate assembly for braille display
The present disclosure relates to tactile displays, for example electro-magnetic Braille displays. In certain disclosed embodiments, tactile displays may comprise capture plate assemblies. Such capture plate assemblies may be removable from tactile displays to facilitate cleaning and/or maintenance of the tactile display.
1. A tactile display, comprising:
a capture plate assembly including one or more display dots;
a top assembly including one or more braille dots, wherein said top assembly is in mechanical communication with the capture plate assembly, and
a membrane positioned between the capture plate assembly and the top assembly, wherein said membrane physically separates said one or more display dots of said capture plate assembly from said one or more braille dots of said top assembly so that said display dots do not contact said braille dots.
2. The tactile display of claim 1 , wherein the capture plate assembly comprises an insulator top plate.
3. The tactile display of claim 1 , wherein the capture plate assembly further comprises an actuator.
4. The tactile display of claim 3 , wherein the actuator comprises a dot.
5. The tactile display of claim 4 , wherein the dot comprises a Braille dot.
6. The tactile display of claim 1 , wherein the capture plate assembly further comprises a stator.
7. The tactile display of claim 6 , wherein said stator comprises a steel top plate.
8. The tactile display of claim 1 , wherein the capture plate assembly further comprises a touch-sensitive surface.
9. The tactile display of claim 1 , wherein the capture plate assembly comprises a foam.
10. The tactile display of claim 1 , wherein the capture plate assembly defines one or more openings.
11. The tactile display of claim 10 , wherein said one or more openings comprise openings for screws, dots, Braille dots, or graphics dots.
12. The tactile display of claim 1 , wherein the capture plate assembly further comprises one or more fasteners.
13. The tactile display of claim 12 , wherein said fasteners are not visible to a user.
14. The tactile display of claim 1 , wherein said capture plate assembly is removable from the tactile display.
15. The tactile display of claim 14 , wherein said capture plate is assembly is reversibly removable from the tactile display.
16. A method for cleaning a tactile display comprising the acts of:
removing a capture plate assembly including one or more display dots from the tactile display, wherein said tactile display includes a top assembly comprising one or more Braille dots;
cleaning said capture plate assembly; and
replacing said capture plate assembly on the tactile display, wherein said capture plate assembly is positionable atop said top assembly so that said top assembly is in mechanical communication with said capture plate assembly.
17. The method of claim 16 wherein cleaning said capture plate assembly includes washing or wiping the removed capture plate assembly.
18. A method for cleaning a tactile display comprising the acts of over-driving one or more actuators.
19. The method of claim 18 , wherein the over-driving of one or more actuators moves debris to a location where it can be removed from the tactile display.
