Patent Images

1. A pre-programmed device for displaying images, comprising:

  • (a) a plurality of electrically powered light emitters in one or more generally continuous rows, the display device being capable of being moved in a path generally perpendicular with the row of lights;

    (b) at least one microprocessor, the light emitters being under direct control of at least one microprocessor;

    (c) at least one motion or speed sensor within the display device; and

    (d) a source of electrical power within, on, or connected to the display device; and

    (e) at least one input/output microprocessor pin on the microprocessor;

    wherein at least one input/output microprocessor pin drives at least one multicolor light emitting diode; and

    wherein at least one of the sensors enables the microprocessor; and

    the microprocessor turns individual light emitters on and off in a time-controlled manner, in order that graphics, words or messages are displayed when the display device is moved at or above a rate of speed sufficient to be viewed by humans.
