摘要： A sequential activation control for selective sequential switching of at least two power circuits including: direct current power supply means to provide direct current source of power at selected voltage, clock means to provide output timing pulses at selected intervals, counter means, with counter controller means to receive the clock pulses having multiple electrical output means wherein a portion of the output means are serially activated by the counter controller in response to a selected number of clock pulses until a selected number of output means have been activated to provide a first activation cycle, multiple switch means, at least one switch means for each output means to be operated by selected output means, reset means to deactivate all of the switch means at selected time after the last output means has been activated so the clock means initiates a new activation cycle where the switch means are adapted to activate associated cooperative power circuits.

摘要： The present invention provides a broad spectrum frequency variable horn arrangement which includes a power supply means, at least two electronic signal generating means driven by said power supply means, with each signal generating means adapted to provide square wave pulsed voltage output of selected amplitude and different frequency periods. Mixing means are provided to additively mix the instantaneous output of each of the signal generating means and means to supply the mixed signal to an audible sound generator means where the amplitude and frequency of the generated audible sound corresponds to the signal received by the mixing means.
