Abstract
A display module which controls a sequence of lights, for interconnection with other modules of the same kind to form a display system. The module controls the intensity of each light in its sequence so as to display a time varying brightness pattern that moves at a selected rate along the sequence. The light pattern may be selected from multiple patterns generated by the module. The display module includes a parallel output for driving other modules so as to synchronously display the same pattern. There is also a serial output, whereby the light pattern, after moving through the sequence of lights associated with the display module, moves through a sequence of lights associated with another module.
Claims6
A display module for interconnection with modules of the same kind, each having a set of lights associated therewith, to form a display system, said module comprising:
- means responsive to control signals for controlling the intensity of each of a plurality of lights in a set associated therewith;
- means for generating said control signals capable of driving said controlling means so as to display a time-varying intensity pattern in the associated set of lights;
- input means for deriving said control signals for said controlling means from an external source, including from another module of the same kind;
- and
- parallel output means for driving a like module so as to synchronously display the same pattern.
A display module for interconnection with modules of the same kind, each having a sequence of lights associated therewith, to form a display system, said module comprising;
- means for controlling the intensity of each of a plurality of lights in a first sequence associated therewith;
- means for driving said controlling means so as to display a time varying intensity pattern moving along said first sequence of lights;
- input means for driving said controlling means from an external source, including from another module of the same kind;
- parallel output means for driving a like module so as to synchronously display the same pattern;
- and
- serial output means for driving a second module of the same kind to display said pattern in a second sequence of lights associated with the second module, in such a manner that the second sequence becomes a continuation of said first sequence.
A display module for interconnection with modules of the same kind, each having a sequence of lights associated therewith, to form a display system, said module comprising:
- means responsive to control signals for controlling the intensity of each of a plurality of lights in a first sequence associated therewith;
- means for generating said control signals capable of driving said controlling means so as to display a time-varying intensity pattern moving at a selectable speed along the associated sequence of lights, including means for selecting the displayed pattern from a plurality of patterns;
- input means for deriving said control signals for said controlling means from an external source, including from another mdoule of the same kind;
- parallel output means for driving a like module so as to synchronously display the selected pattern;
- serial output means for driving a second module of the same kind to display said pattern in a second sequence of lights associated with the second module in such a manner that the second sequence becomes a continuation of said first sequence;
- and
- means responsive to a modulating signal for controlling the intensity of all the lights in said first sequence in accordance with the modulating signal.
