A crossed light beam position indicator includes orthogonal arrays of paired light emitters and detectors for covering a display surface with crossed light beams and scanning means coupled to the emitters and detectors for electronically scanning the orthogonal arrays such that a single emitter at any one time is emitting light. Improved initialization means detect the first occurrence of an interrupted light beam and in response to the first detection, reset the scanning means to the initial reset position to thus avoid transmitting an address that migh...


In a scanning system for scanning a display surface with light beams including a plurality of paired light emitting sources and oppositely positioned light detectors adjacent respective opposite edges of a display surface and scan means for sequentially activating said emitting sources and oppositely positioned detectors in predetermined patterns to scan said display surface with light beams emitted by said sources and impinging on said detectors, the improvement comprising: means responsive to the first detection by one of said detectors of an interrupt...
