Abstract: An apparatus for allowing display modules to communicate information about themselves to other display modules in the same display panel, comprising a module-based display panel wherein each face of the panel comprises a plurality of display modules, wherein the transmitters, receivers and/or transceivers are configured so that each transmitter or transceiver on a given display module is adjacent to a receiver or transceiver on an adjacent display module, wherein the transmitters or transceivers on a given display module transmit information about that display module to the adjacent receivers or transceivers, wherein the receivers or transceivers on a given display module receive information about the adjacent display module from the adjacent transmitters or transceivers, and wherein the information is used by the display modules and/or a main controller to determine the location of the display module within a display panel.

Abstract: A hand-held apparatus and process for measuring the gap and mismatch of two adjacent surfaces. The apparatus includes two strobe lights positioned within a hand-held housing. An optical interface within the housing directs a portion of the light generated by each light source into substantially parallel planes which are projected out of the opening of the housing at converging angles onto the surfaces to be measured. A camera within the housing captures the resulting image and generates a signal corresponding to the image. A signal processor which includes a frame grabber card processes the signal generated by the array of detectors to thereby calculate the amount of gap and mismatch between the surfaces being measured.
