1. A remote radio control system for actuating special effects devices comprising:
- (a) a special effects device mounted in a first location;
(b) first and second radio receiver circuits mounted adjacent said special effects device, said first and second receiver circuits being tuned to receive first and second radio signals, respectively;
(c) said first receiver circuit being connected to said second receiver circuit so as to activate said second receiver circuit only when said first signal is received by said first receiver circuit;
(d) a radio transmitter, said transmitter including means for generating and transmitting said first and second radio signals to said first and second receiver circuits; and
(e) circuit means connected between said second receiver circuit and said special effects device for actuating said device when said first and second signals are simultaneously received by said first and second receiver circuits, respectively.

18. A remote control system for actuating theatrical special effects devices comprising:
-
(a) at least one theatrical special effects device selected from the group comprising a confetti-filled device, a lighting device, and a pyrotechnic device; (b) a transmitter, said transmitter including means for generating and transmitting first and second signals; (c) means mounting said theatrical special effects device at a location remote from said transmitter; (d) first and second receiver circuit means mounted adjacent said theatrical special effects device at said remote location; (e) said first and second receiver circuit means being receptive to only said first and second signals, respectively; (f) said first receiver circuit means being connected to said second receiver circuit means for activating said second circuit means only upon receipt of said first signal; and (g) said second receiver circuit means including means for activating said theatrical special effects device only when said second circuit means has been activated by said first receiver circuit means and said second receiver circuit means receives said second signal. - View Dependent Claims (19, 20)
