Abstract
An illuminated sign system is comprised of independent sign modules that may be used individually or associated with additional sign modules to form a sign matrix of variable size and shape. Individual sign modules are independently capable of displaying text or graphics stored in the sign module's memory or as entered by a user. Larger signs can be easily created in the field by connecting multiple sign modules together into a matrix. Control circuitry in the modules detects the presence of adjacent modules and shifts control of the matrix display to the module in a master position. The text or graphics on the module in the master position is preferably resized to fit the size of the matrix. A user can control the entire matrix by controlling the module in the master position.
Claims23
A sign module, comprising:
- a display configured to display a message;
- a processor configured to control the display;
- and
- at least one communication port connected to the processor for communicating with a second sign module having a display;
- wherein the sign module, when used in association with a second sign module, is configured to determine whether to operate as a master sign module or a slave sign module relative to the second sign module;
- and if the sign module determines to operate as a master sign module, the sign module is configured to communicate with the second sign module to control the message on both its display and the display of the second sign module;
- and if the sign module determines to operate as a slave sign module, the sign module is configured to communicate with the second sign module and display a message received from the second sign module;
- otherwise when not used in association with a second sign module, the sign module is configured to control only the message on its display.
