Patent ID: 8638201

Claim:
A wildlife dislodging device comprising: a first oscillating circuit; a counter that counts pulse number of an output signal of said first oscillating circuit; a designated value-generating circuit that designates values to be counted by said counter; a second oscillating circuit that changes the designated value of said designated value-generating circuit at an interval of predetermined time; a comparator circuit that compares the count value of said counter with the designated value of said designated value-generating circuit, and outputs a pulse signal and resets said counter when said count value reaches said designated value; an output circuit that amplifies the pulse signal of said comparator circuit; sound transforming means for transforming the pulse signal of said output circuit into sound; a delay circuit that delays time of transmitting the designated value of said designated value-generating circuit to said comparator circuit; and an initial value-changing circuit that changes an initial value of said counter during said delay time.
